A cross between the ISA-Brown industrial strain and an Algerian local (Kabyle) breed was compared with the Algerian local (Kabyle) hen. The comparison during the egg production period was done in individual cages, in a ventilated henhouse without any particular isolation. The same commercial diet has been provided over three time periods (35 to 36 weeks, 50 to 51 weeks and 65 to 66 weeks of age). Egg number and body weight at first egg was significantly lower in the Kabyle local breed. Mortality was almost equal during the breeding period and the egg production periods for the two genotypes. The Kabyle hen eggs, in spite of a weight which was lower (43.70 to 53.37 g according to the age), gave yolk to albumen ratio similar to the ISAKAB cross (0.52 to 0.58 according to age). Finally, the ISAKAB cross was better in terms of egg production and egg quality than the local hen, in test conditions. [less ▲]

The objectives of this work were to evaluate the optimal body size variable, and to determine mathematical model that best fits echocardiographic measurements to body size in the equine species. 150 horses of various breeds, aged 1 week to 17 years old, body weight (BW) 38 to 890 kg, and free from cardiac disease were used in this study. Based on their age (i.e. younger or older than 2 years), animals were separated into 2 groups. In each horse, the body weight (BW), height at withers (HT), thoracic circumference (TC) and the body length (BL) were measured, the body surface area (BSA) was calculated, and a standard two-dimensional and M-mode echocardiography was performed allowing classic cardiac measurements to be taken. Correlations between each echocardiographic measurement and each of the anthropometric variables were assessed via a Pearson’s product-moment analysis and using linear, logarithmic, and power regression analysis in all animals and within the 2 groups. The dimensional, but not the functional, echocardiographic measurements showed a close correlation with all body size variables, especially during growth. The relationship between cardiac measurements and body size was best described using power regression models with TC as the anthropometric variable, but the relationship was also very accurately described using BW, BSA, or BL. In the equine species, dimensional echocardiographic reference values should be established using power regression equations on TC. Such a correction for body size could increase the diagnostic value of echocardiography in equine cardiology. [less ▲]

Pulmonary diseases are common in horses and have a major economic impact on the equine industry. Some of them could be associated with an inadequate immune response in the lung, but methods to evaluate this response in horses are lacking. The aim of this study was to develop and validate an experimental model that could be applied in several physiological and pathological conditions to assess the innate immune response of equine pulmonary cells. Equine alveolar macrophages (AMs) obtained from bronchoalveolar lavages were isolated from other cells by adhesion. TLR2, 3, and 4 expression in AMs was studied and their responses to commercial ligands (respectively FSL-1, Poly(I:C), and LPS) were evaluated after determination of the appropriate dose and time of incubation. TLR responses were assessed by measuring cytokine production using (1) gene expression of TNFalpha, IFNbeta, Il-1beta, and IFNalpha by qPCR (indirect method); and (2) cytokine production for TNFalpha and IFNbeta by ELISA (direct method). TLR 2, 3, and 4 were expressed by AMs. TLR 2 stimulation with 10ng/mL of FSL-1 during 3h significantly increased IL-1beta and TNFalpha gene expression. TLR 3 stimulation with 1000ng/mL of Poly(I:C) during 1h increased IFNbeta, IFNalpha, Il-1beta and TNFalpha expression. TLR 4 stimulation with 100ng/mL of LPS during 3h increased TNFalpha, IFNbeta, and Il-1beta expression. Results obtained by ELISA quantification of TNFalpha and IFNbeta produced by AMs following stimulation during 6h were similar: FSL-1 increased TNFalpha production but not IFNbeta, Poly(I:C) and LPS increased production of IFNbeta and TNFalpha. In conclusion, pulmonary innate immunity of horses can be assessed ex vivo by measuring cytokine production following stimulation of AMs with TLR agonists. This experimental model could be applied under several conditions especially to improve the understanding of equine respiratory disease pathogenesis, and to suggest novel therapeutic opportunities.

This study was conducted to evaluate the effects of genetic background and season on growth performance and semen quality of boars. Five genetic groups were evaluated, including stress-negative Piétrain boars with CC (PiCC) or CT (PiCT) halothane genotypes, and Piétrain x Duroc hybrid boars with various compositions (25% (PiDu25), 50% (PiDu50) or 75% (PiDu75) of Piétrain origin). The results showed that genetic group has a significant effect on growth performance and semen quality. The hybrid boars PiDu25, PiDu50 and PiDu75 had better growth rate, but lower lean <br />meat in comparison with pure stress-negative Piétrain, except PiDu75 boars. PiDu25, PiDu50 and PiCC boars demonstrated high semen quality. A season effect was observed on most of semen quality traits of pure stress-negative Piétrain as well as hybrid boars with different genetic constitution. Sperm concentration was lower in Summer and Autumn, higher in Winter and Spring. The Piétrain x Duroc hybrid boars, especially PiDu75 seem to be promising as terminal boars. [less ▲]

The objective of the present study was to compare Duroc (DU) and stress-negative Piétrain (PI) as terminal sires mated to F1(Large White x Mong Cai) sows (F1) on productivity, carcass characteristics, meat quality and meat chemical composition under household conditions in Hai Duong province, Vietnam. The reproduction performances were based on 74 litters of 42 F1 sows from 12 households and the semen from 11 Duroc and 10 Piétrain boars. Data on production and carcass traits were collected from 76 DUxF1and 67 PIxF1 crossbred fattening pigs. Longissimus dorsi samples from 55 and 37 of DUxF1 and PIxF1 respectively were analyzed to determine meat quality and meat chemical composition. The results show that household affected production, carcass, and meat quality traits (P<0.05) as well as reproduction (weights at birth and weaning, P<0.01). Inversely, boar breeds did not influence (P>0.06) on reproduction traits (except individual weight of born alive pigs and weaned pigs, P<0.01), production traits, meat chemical composition and meat quality (except pH at 4 days post mortem, P<0.05) while lean meat percentage of Piétrain-sired pigs was higher than those of Duroc-sired pigs (P<0.05). The utilization of Piétrain boars does not affect reproduction performances, growth rate and meat quality while improving lean meat percentage in comparison to Duroc boars. This suggests that the use of stress-negative Piétrain boars as terminal sires would improve lean meat percentage under household conditions in North Vietnam. [less ▲]

Little is known about the effect of various animal's signalment variables on echocardiographic reference values in the equine species. This study was performed to evaluate the effect of sex, breed, age and body weight (BW) on echocardiographic measurements in the equine species. Echocardiography was performed on 212 ponies or horses of various breeds, aged from 1 day to 37 years old (mean ± SD: 7.8 ± 5.8 years), BW 38-890 kg (mean ± SD: 421 ± 133 Kg), and free of cardiac disease. Fifty of those animals aged from 2 months to 35 years old (mean ± SD: 11.6 ± 6.4 years old); BW 77-662 kg (mean ± SD: 436 ± 135 kg) were also examined using the pulsed-wave Doppler mode. Standard two-dimensional and M-mode echocardiography were performed on all animals. Standard pulsed-wave Doppler examination of each cardiac valve was performed on the 50 first examined animals. Data were analysed using a general linear model including the effect of sex, age, breed and BW after logarithmic transformation of the data. Therefore, the same analysis was performed separately on animals aged  2 years-old and on older animals. All dimensional echocardiographic measurements were significantly affected by BW and most of them were significantly affected by breed, but not by sex. Only the aortic and the pulmonary artery internal diameter were significantly affected by age. None of the Doppler measurements were significantly affected by the tested variables. In conclusion, in the equine species, dimensional echocardiographic reference values should be established using regression equations as a function of BW, which could increase the diagnostic value of this leading technique in equine cardiology. Breed could also have an effect on those measurements. [less ▲]

The objective of the present study is to investigate the reproduction, production and semen traits of the stressnegative Piétrain line of pigs in the north of Vietnam, as well as to identify various factors (halothane genotype, generationorigin, parity, sex and month of the year) acting on these traits. The experiment was carried out on a purebred nucleus on Dong Hiep farm, Haiphong province in Vietnam. The reproduction performances and the sperm quality measures were based on 12 sows and 5 boars imported from Belgium as well as on 29 sows and 14 boars born in Vietnam, while the production performances were recorded only from 251 animals born in Vietnam. No significant differences were observed between halothane genotypes of sows for reproduction traits (P>0.0578). At the age of 7.5 months, bodyweight, backfat thickness and longissimus depth (7.5) of homozygous-dominant pigs were higher (P<0.05) than in heterozygotes. Homozygous-dominant boars had higher total number of spermatozoa than heterozygote boars (P < 0.05); similarly, Vietnam boars also presented higher total number of spermatozoa values than Belgium boars (P < 0.001). Vietnam sows had longer duration of pregnancy, more piglets born alive and heavier litter weight of weaning than Belgium sows (P < 0.01). Bodyweight at birth, at weaning, at 2, 5.5 and 7.5 months of age increased from the first to third parity (P < 0.05). Gilts had more lean meat than intact boars (P < 0.01). Compared with observations made in temperate countries, the reproduction and production performances, sperm concentration and total number of spermatozoa of stress-negative Piétrain pigs were reduced, whereas lean meat percentage was not affected. This might be due to the different climate, although improving values for animals born in Vietnam might indicate adaptation of the animals and/or of the technicians with that breed. The results support the interest of the use of this new Piétrain line in tropical countries with ecological and climatic conditions similar to Vietnam. [less ▲]

Data recorded between 2008 and 2012 from Dong Hiep pig farm, Vietnam, was used to stimate genetic parameters for weights at birth (WB), weaning (WW) and 60 days (W60) of stress negative Piétrain pigs using restricted maximum likelihood methodology. WB, WW and W60 were recorded from 1146, 839 and 610 animals respectively. The data were analyzed according to a mixed model including 4 fixed effects, parity, season, sex, and interaction between halothane genotype and country of origin (Belgium and Vietnam) of sows. Additionally, 3 random effects (maternal common environment for litter, direct and maternal additive genetic) for WB and 2 random effects (maternal common environment for litter and direct additive genetic) for WW and W60 were included in the model. Estimates of direct heritability and proportion of the maternal common environmental variance for WB, WW and W60 were 0.20, 0.13; 0.22, 0.21 and 0.19, 0.30 respectively. In addition, the estimate of maternal heritability for WB was 0.14. These genetic parameters suggest that WB, WW and W60 could be improved by selection using both direct and maternal effects.

La race Koundoum, un des rares moutons à laine du Sahel, est victime des croisements avec d’autres races plus productives et de la dégradation de son biotope originel, le fleuve Niger. Cette race possède des qualités intéressantes d'adaptation au milieu et de production de laine, qui justifient la mise en œuvre d’un programme de conservation de ce patrimoine génétique original. Dans cette optique, notre étude vise à la caractérisation de la race Koundoum afin d’établir les fondements d’un plan pour sa conservation. Il a ainsi été procédé à la caractérisation morpho-biométrique de moutons de race Koundoum auprès de 26 éleveurs, principalement de la commune de Kourteye. Au total, l’étude a porté sur 147 sujets (45 mâles, 102 femelles), dont 56 de moins d’un an. La couleur de robe noire domine (62,6%), suivie de la couleur blanche (27,9%). Les pendeloques sont présentes chez 40,0% des mâles et 26,5% des femelles. Presque tous les béliers portent des cornes (95,6%) contre 3,9% des brebis. Le périmètre thoracique a été retenu pour l’estimation d’une équation barymétrique en raison de sa forte corrélation avec le poids (R2 = 0,88). Des formules de prédiction du poids ont pu être proposées selon le sexe et l’âge. En dépit du manque de contrôle des croisements par la majorité des éleveurs inclus dans l’étude, l’échantillon a révélé des caractéristiques relativement homogènes. La détermination d’une formule barymétrique pourra venir en soutien d’une sélection incluant un objectif de croissance. [less ▲]

This study was carried out in Dong Hiep pig farm, North of Vietnam in order to evaluate the semen quality of stress negative Piétrain and Duroc boars. A total of 722 ejaculates from 13 homozygous (CC), 7 heterozygous (CT) stress negative Piétrain and 10 Duroc CC boars was collected between 2008 and 2012. The sperm quality was assessed on each ejaculate using ejaculate volume (VOL), spermatozoa motility (MO), sperm concentration (CO) and total number of spermatozoids (NT). Genetic type of boars, season, year and (season x year) as well as (genetic type x year) interactions were included in the model as fixed factors. The results show that the semen quality was influenced by all studied effects (p<0.05) except VOL for season (p=0.45) and season x year (p=0.55), and CO for genetic type (p=0.93). VOL and NT (291.74ml and 103.37×109spz) of Piétrain CC were higher than those (241.40ml and 84.58×109spz) of Piétrain CT and (228.05ml and 77.15×109spz) of Duroc (p<0.001) although the values of the 3 genetic groups are in the range of normal semen. MO, CO and NT tend to be higher in cold than in hot season (p<0.001). These results suggest that semen from Piétrain and Duroc boars could be used in tropical climatic conditions (particularly Piétrain CC) and that the semen quality could be improved through reduction of heat stress.

Due to positive externalities and the need to work on a large scale, animal breeding is usually carried out by breeders associations or states. In Algeria, racehorse breeding is in the hands of unorganized breeders-owners. Through a survey conducted with 461 owners-breeders between 2009 and 2011, this study investigates their perceptions, objectives and practices regarding selective breeding. Racehorse breeding is a full-time professional activity for a third of interviewees. The holdings are small-sized with 77% owning one or two mares. The regular practice of insemination could categorize breeders according to their professionalization (38.4% professional vs. 61.6% occasional breeders). Seniority in the sector was also used to classify breeders, considering as “young” the breeders under 10 years experience (38.8%) and as “senior” those above 10 years (61.2%). More than professionalization, seniority shows a significant impact on practices and objectives. Thus, seniority influences breed choice (young breeders tend to specialize while senior own both Arabian and Thoroughbreds; p<0.001), age at first foaling (sooner among senior breeders; p<0.01), information sources considered for selecting stallions (senior use more diversified sources; p<0.01), the importance granted to the price of insemination (greater for the young breeders; p<0.001), the importance granted to the ranking compared to earnings (the ranking being more important to young breeders, p<0.001), and the priority given to breeding (young breeders give rather priority to a buy-race-resell activity; p<0.001). Finally, racehorse breeding in Algeria is poorly professionalized, the only financial goal being cost coverage. Despite inappropriate practices, an interest for selection is noticed. [less ▲]

Selective breeding of Arabian horses in Algeria is not yet well developped. No accurate estimation of the breeding values of racing horses is carried out untill now. The estimation is based on one or several measurable traits, linked to race performance. To allow for an accurate estimation, it is important to determine the part of the phenotypic variability that is due to non-genetic factors (environmental). This first study estimates phenotypic correlations between the recorded traits in order to deduce to what extent the different measures bring different information on animal performance. Then it estimates the influence on performance of non-genetic factors such as sex, age, year of performance and the interactions between these various factors. From 1995 to 2007, the data related to flat racing was collected. The General Linear Model was used to identify and quantify the non-genetic factors affecting racing performances. Three traits were used: two earnings traits (the logarithm of annual virtual earnings: LAEV and the logarithm of average annual virtual earnings per start: LAEV/S), and one ranking trait (the ranking transformed and normalised: PERF). Significant high positive correlations was observed between the three traits (p<0.001), which thus give account of similar informative aptitudes. The effects of sex, age, year as well as the interactions between age and sex and between age and year turned out to be significant for the three traits (p<0.05). These results indicate the need to adjust the earnings and ranks traits in order to use them as criteria of selection of racing Arabian horses. [less ▲]

La poule Ardennaise est une race emblématique de la biodiversité avicole belge. Dans un contexte mondial favorable à la conservation des races locales d’animaux domestiques, cette étude est consacrée à la comparaison de deux variétés de la race Ardennaise (Noire dorée et Noire Argentée). La comparaison est réalisée par le biais de trois études: (1) caractérisation morpho-biométrique des deux variétés; (2) caractérisation de la croissance et de la qualité de la carcasse et de la viande; (3) suivi du taux de ponte pendant 52 semaines et l’étude de la qualité des œufs à 30, 45, 60 et 75 semaines d’âge. Des différences significatives ont été enregistrées au niveau des poids corporels, du grand diamètre du tarse, de la longueur du tarse et de la taille de la crête des deux variétés. La variété de la poule Ardennaise n’influence pas significativement les caractères quantitatifs et qualitatifs de production de viande (rendement, poids après abattage, pH, couleur de la viande). Elle influence cependant significativement le poids de l’œuf entier, le poids du blanc, le pourcentage du blanc, le pourcentage du jaune, le rapport jaune/blanc et le pH du blanc (p<0,05). Pour plusieurs caractères morphologiques, d’engraissement et de ponte, les deux variétés ne présentent aucune différence significative. Il serait intéressant de compléter cette étude par une analyse moléculaire permettant de préciser le degré de similitude génétique entre les deux variétés et éventuellement avec les autres variétés de la race.

La Kabylie est une région côtière montagneuse du nord-est algérien. Ce poster présente les principales espèces et races élevées dans cette région. Les ovins sont représentés par la race Tazegzawt, répertoriée récemment. Elle est reconnaissable à ses tâches noires à reflets bleuâtres, son nom kabyle signifiant bleu. Son poids peut dépasser 30 kg à 6 mois. La population locale de chèvres n’a pas fait l’objet de descriptions. Toutefois, la chèvre locale est adaptée aux massifs montagneux. Elle est de petite taille avec un poids vif d’environ 25 kg. Elle présente de longs poils et différentes couleurs de robe. La race bovine locale est issue de l’adaptation de la race brune de l’Atlas à un climat tempéré. Elle possède un petit gabarit (de 250 à 300 kg) et une robe grise ou allant du fauve brunâtre au rouge-brun. Par l’industrialisation de la production de volailles, les poules locales ont subi une érosion génétique sévère. Elles présentent ainsi une grande variabilité phénotypique et sont de taille moyenne (autour de 1,5kg). Le lapin local connaît une situation similaire et présente un poids de 2 à 3 kg. Il existe une tradition apicole importante en Kabylie. Les types d’abeilles exploitées ne sont toutefois pas encore caractérisés. Toutes les races citées ici sont menacées par le croisement ou l’abandon. Leur caractérisation génétique et zootechnique est nécessaire pour l’amélioration des systèmes de production familiaux, plus particulièrement en régions montagneuses, et la conservation de la biodiversité.

Quality variations of retailed eggs are widely reported. This study aims at assessing the quality of eggs according to the marketing channel in the department of Bejaia (Algeria). In spring and summer 2012, a total of 3330 eggs were bought in 30 stores divided into 3 categories: 10 supermarkets (1146 eggs), 10 public markets (1048 eggs), and 10 shops (1136 eggs). The eggs weights differed significantly with the marketing channel with 58.9±0.14, 61.2±0.13 and 62.8±0.13 g for public markets, shops and supermarkets, respectively (p<0.001). Although the shell thickness was similar for all marketing channels, the proportion of damaged eggs was higher in public markets (9.0%), intermediate in shops (7.3%) and lower in supermarkets (5.7%; p<0.05). The yolk/albumen ratio was significantly higher for eggs from supermarkets (48.1%) compared to the other channels (around 47.4%; p<0.05). The freshness of the eggs, measured by the Haugh method, was lower in public markets (74.3 units), intermediate in shops (77.6 units) and higher in supermarkets (79.9 units; p<0.05). The price of eggs, expressed in Algerian Dinar (AD) per kg, was significantly lower in public markets (124 AD/kg) compared to the two other channels (around 131 AD/kg; p<0.05). One can conclude that egg quality in Basse Kabylie differs significantly between marketing channels with higher quality observed in supermarkets. The lower quality of eggs in public markets is associated with lower price. Eggs from shops present an intermediate quality. A one-year study would allow studying both the potential seasonal effect and compare intrinsic variability across marketing channels. [less ▲]

Background Pulsed wave (PW) Doppler echocardiography has become a routine non invasive cardiac diagnostic tool in most species. However, evaluation of intracardiac blood flow requires reference values, which are poorly documented in goats. The aim of this study was to test the repeatability, the variability, and to establish the reference values of PW measurements in healthy adult Saanen goats. Using a standardised PW Doppler echocardiographic protocol, 10 healthy adult unsedated female Saanen goats were investigated three times at one day intervals by the same observer. Mitral, tricuspid, aortic and pulmonary flows were measured from a right parasternal view, and mitral and aortic flows were also measured from a left parasternal view. The difference between left and right side measurements and the intra-observer inter-day repeatability were tested and then the reference values of PW Doppler echocardiographic parameters in healthy adult female Saanen goats were established. Results As documented in other species, all caprine PW Doppler parameters demonstrated a poor inter-day repeatability and a moderate variability. Tricuspid and pulmonary flows were best evaluated on the right side whereas mitral and aortic flows were best obtained on the left side, and reference values are reported for healthy adult Saanen goats. Conclusions PW Doppler echocardiography allows the measurement of intracardiac blood flow indices in goats. The reference values establishment will help interpreting these indices of cardiac function in clinical cardiac cases and developing animal models for human cardiology research. [less ▲]
