The Kabyle goat breed represents 10.52% of the total Algerian market (3.8 million heads). A survey of 69 farmers has been carried out in order to characterize it and its breeding in the District of Chemini. The questions focused on household agricultural activities, including breeding of goats, cattle, sheep, rabbits, chicken, turkeys, honeybees and the production of olive oil and figs. The goat morpho-biometric characterization was based on 18 corporal measurements. The Hierarchical Cluster Analysis (HCA) of the farm structures defined four groups of farms, variance between groups accounting for 55.7% of total variability. The average number of goats in groups 1 to 4 was 7.2±2.8, 11.1±3.5, 22.3±1.4 and 3.4±1.0, respectively. Group 3 (n=6), showed the greatest number; it consists of older farmers (67 years old or over) not practicing arboriculture. They also have the largest numbers of sheep (48.67), rabbits (50.83), chicken (48.33) and turkeys (42). Group 4 (n=9), with the lowest number of goats, was the group of young farmers (39 years old or less), more dedicated to cattle breeding (~52 heads) and the production of olive oil (~207 trees) and figs (~47 trees). The 18 morpho-biometric variables were significantly higher in males than in females (p<0.05). The Kabyle goat is small (Height at withers: male: 68.23±0.97cm and female: 65.41±0.55cm) with long hair (male: 12.24±0.51cm, and female: 9.51±0.29cm). Its ears are drooping, its convex profile has a slightly pronounced nasal split and its dress color ranges from dark brown to black. This adapted genetic resource should be key in the development of a local production, based on a strong commitment of farmers inside a breed association, for the production of specimens corresponding to a standard, to be determined collectively.

The purpose of this paper is to examine the viewpoints of stakeholders in the management and conservation of farm animal biodiversity in Niger. The research applies Q methodology in order to reveal consensual and divergent discourses. After the development of the set of items on the topic of biodiversity (Q sample), the statements were sorted by the respondents through a 7-grade scale, from −3 to +3. The analysis of Q-sort data with the qmethod package under the R software highlighted three distinct stakeholder viewpoints on the importance of biodiversity in agriculture and animal husbandry, the balance between progress and preservation and the effectiveness of different methods of conservation. The study shows an apparent consensus on the importance of biodiversity that is obviously a promoted topic in the country. Behind the consensus, different discourses are defined that all appear divided by the same dilemma between conservation and economic development. Understanding the different answers and weight attributed to each of the components of the dilemma will guide awareness-raising campaigns and help to pinpoint divergent interests among stakeholders.

Strong increase in demand for animal products could benefit local producers in developing countries. This development opportunity particularly concerns suburban livestock. In Burkina Faso, the suburban area of Ouagadougou is a place for the setting up of an increasing number of breeders. Due to its importance in religious traditions, spurring its consumption in whole West Africa, mutton is a major part of this suburban production. In order to characterize sheep farming in the suburban zone of Ouagadougou, in terms of motives, practices, and economic performance, and to better understand the dynamic at play in the sheep sector, a survey has been conducted among 80 sheep farmers around Ouagadougou. The results show that suburban sheep keeping is a highly dual sector. Nearly half (42.5 %) of farms may be described as traditional livestock, while 50% are evolving towards intensification. These two groups essentially differ in terms of animal genetic and feeding management, farm infrastructure, and farmer education level. Economically, the whole sample tends to indicate a lack of profitability of the activity in terms of monetary income. Several factors contributing to this situation are pinpointed, namely feed and animal health constraints, flock and production management, and the market conditions. [less ▲]

In Niger, the growth in local demand for milk and meat makes it necessary to consider a genetic improvement of indigenous cattle. In Toukounous breeding station, the Azawak zebu has undergone over 50 years of line breeding for milk and meat production traits. To understand the diffusion potential of improved Azawak sires in Niger, this study proposes to estimate the values that cattle keepers ascribe to different breeding criteria. In a first participatory stage, the breeding criteria used by cattle keepers were first listed and their relative importance was semi-quantified in three different production zones: agricultural, peri- urban and pastoral. The willingness-to-pay (WTP) for chosen breeding criteria have then been estimated through stated preference methods with 150 breeders. From participatory surveys, the most important attributes in sire choice were reproductive performance, feeding requirements, and docility. The criteria considered for conjoint analysis were feeding requirements, docility, meat or dairy type, reproductive performance, coat color, and tail length. The WTP was 149 € for low feed requirements, 139 € for docility, and 132 € for a long tail. The meat or dairy type of the sire showed a lesser importance in the decision-making. [less ▲]

The diffusion of highly productive breeds across developing countries goes along with a neglect of indigenous breeds, which are well suited to their environment but often show low yields. Thus, in Niger, the flock of Koundoum sheep are rapidly decreasing. The Koundoum is one of the few wool sheep breeds of Africa and shows important adaptive feature to its native environment, i.e. the humid pastures on the banks of the Niger River. To characterise the breed and to understand its production context, a survey has been conducted in 104 herds in four communes along the Niger River (Kollo, Tillabery, Say and Tera). Nine body measurements, including live weight, were taken on 180 adult sheep (101 females and 79 males). The herds varied from 2 to 60 heads, with a median size of eight animals and two thirds of the herds having less than 10 animals. Mainly fed on natural pastures, 85.6% of the herds received crop residues. Only natural mating was practiced. Veterinary care was restricted to anti-helminthic and some indigenous treatments. The frequent affiliation of breeders to professional unions appeared as favourable to the implementation of a collective conservation program. The Koundoum sheep were white or black coated, with the black colour being most frequent (75.6%). Wattles were present in both sexes at similar frequencies of around 14%. All biometric variables were significantly and positively correlated between them. The thoracic perimeter showed the best correlation with live weight in both males and females. Three variables were selected for live weight prediction: thoracic perimeter, height at withers and rump length. From the present study, it is expected that the in situ conservation of the Koundoum sheep will be highly problematic, due to lack of market opportunities for wool and the willingness of smallholders to get involved in pure Koundoum rearing.

Facing growth in demand, dairy production in peri-urban areas of developing countries is changing rapidly. To characterise this development around Bamako (Mali), this study establishes a typology of dairy production systems with a special focus on animal genetic resources. The survey included 52 dairy cattle farms from six peri-urban sites. It was conducted in 2011 through two visits, in the dry and harvest seasons. The median cattle number per farm was 17 (range 5–118) and 42% of farmers owned cropland (8.3± 7.3 ha, minimum 1 ha, maximum 25 ha). Feeding strategy was a crucial variable in farm characterisation, accounting for about 85% of total expenses. The use of artificial insemination and a regular veterinary follow-up were other important parameters. According to breeders’ answers, thirty genetic profiles were identified, from local purebreds to different levels of crossbreds. Purebred animals raised were Fulani Zebu (45.8 %), Maure Zebu (9.2 %), Holstein (3.0 %), Azawak Zebu (1.3 %), Mere Zebu (0.5%) and Kuri taurine (0.1 %). Holstein crossbred represented 30.5% of the total number of animals (19.0% Fulani-Holstein, 11.2% Maure-Holstein and 0.3% Kuri-Holstein). Montbéliarde, Normande and Limousin crossbreds were also found (6.6 %, 0.7% and 0.3 %, respectively). A multivariate analysis helped disaggregate the diversity of management practices. The high diversity of situations shows the need for consideration of typological characteristics for an appropriate intervention. Although strongly anchored on local breeds, the peri-urban dairy systems included a diversity of exotic cattle, showing an uncoordinated quest of breeders for innovation. Without a public intervention, this dynamic will result in an irremediable erosion of indigenous animal genetic resources. [less ▲]

This work investigates laying performances and egg quality of 200 quails during 266 laying days. The first collected 240 eggs, for the periods: 12, 16, 20, 24, 28, 32, 36, 40, 44 weeks were used in this study. The average laying rate calculated over a period of 37 weeks is 74.44 %. All studied eggs quality parameters were significantly (p<0.001) influenced by the age of the quail. The average weight of the whole egg (13.66 g), yolk (3.99 g) and shell (2.28 g) reach their maximum value at the 40th week. The maximum albumen average weight (7.45 g) was observed at 32nd week. Albumen (12.02) and yolk (48.72) indices recorded their highest values at the 12th and the 16th weeks, respectively. The eggs freshness, expressed here by Haugh units decreased with age. They range from 89.56 at the 12th week to 83.71 at the 44th week of age. Yolk color registered values with irregular fluctuations (7.12 to 9.33) in a colorimetric scale of 15 ladders. Highly significant and positive correlations (p<0.001) and were recorded between the whole egg weight and the weight of albumen, yolk and shell. To conclude, the quail age affects significantly the various egg quality parameters. [less ▲]

La fièvre catarrhale ovine (FCO) est une arbovirose qui affecte les ruminants domestiques et sauvages. Depuis sa récente apparition en Europe du Nord, cette épizootie virale a engendré des pertes économiques considérables. Les vecteurs biologiques du virus de la FCO sont des moucherons piqueurs appartenant au genre Culicoides (Diptera : Ceratopogonidae). Plusieurs campagnes de piégeage lumineux de ces moucherons adultes ont été réalisées précédemment en Belgique au sein d’exploitations bovines et ovines, mais aucune à l’intérieur des exploitations porcines. Cette étude vise donc à évaluer, au moyen de pièges lumineux, les populations de culicoïdes éventuellement présentes à l’intérieur de deux porcheries belges au cours de l’automne et de l’hiver 2008. La présence des espèces (potentiellement) vectrices du genre Culicoides a ainsi été mise en évidence à l’intérieur de ces bâtiments durant l’automne : 8 et 749 spécimens appartenant à 2 et 7 espèces ont ainsi respectivement été piégés au sein des porcheries, avec une majorité de femelles du complexe Obsoletus. L’ouverture des bâtiments semble fortement influencer leur présence. L’observation du statut alimentaire des femelles laisse supposer que ces moucherons sont susceptibles de se nourrir ou de pondre au sein des porcheries, même si le sang de porc n’a pas pu être identifié dans l’abdomen des femelles gorgées et que le lisier n’a pas révélé la présence de larves. Les porcs pourraient ainsi intervenir dans le maintien des populations d’espèces potentiellement vectrices du virus de la FCO, ou du nouveau virus dénommé virus Schmallenberg. [less ▲]

The objective of this study was to evaluate the effects of the inclusion of Urtica dioica leaves meal in diets on growth performances and carcass characteristics of broiler chicken. The study was conducted from May to June 2014 in the area of Chemini (Algeria). In a completely randomized design, a total of 100 one-day-old broilers (industrial strain) were divided into 2 groups and 2 repetitions with 25 chickens each. Group 1 was the control group fed a standard commercial diet based on corn and soybean purchased on the local market, whereas the birds in group 2 were fed the nettle diet (control diet with addition of 2% of nettle). The animals were housed inside in experimental pens and fed ad libitum. The results showed that nettle inclusion significantly promotes growth performance of broilers at 42 days of age (1644.8 ± 45.5 vs. 1565.1 ± 45.5g; P<0.05). The broilers fed the nettle diet had higher thigh yield (26.0 ± 0.3 vs. 25.2 ± 0.3%; P<0.05) but lower abdominal fat yield (4.39 ± 0.16 vs. 3.90 ± 0.16%; P<0.05). No significant effect of the diet was observed for carcass yield (around 71.1%) and breast percentage (around 32.40%). The overall mortality was not significantly different (P>0.05) for any of the dietary regimens (around 20%). Feed conversion ratio of the two groups were very close (around 2.17). This experiment showed that dietary inclusion of Urtica dioica has positive effects on growth performance and carcass quality of broilers. [less ▲]

The livestock sector plays a dynamic role in the economic development of rural areas in Algeria. Due to its adaptation to harsh environments, goat breeding is practiced in many areas of the country. To the north, it is confined to mountainous areas, but the bulk of the workforce is left in the steppe and semi-desert areas. The goat population in Algeria reached 3.8 million heads, ranking second after sheep. The present work contributes to a better characterisation of local goat in Kabylie for production and reproduction traits. The study was conducted in the regions of Chemini (Bejaia province) and Bouzeguene (Tizi-Ouzou province). A survey was conducted in 29 herds. The results revealed that the overall mean of goats per households was 6.69 ± 2.97. The purposes of keeping goat in Chemini and Bouzguene was private consumption of milk (82.76%) and meat (68.97%) as well as for commercial exchange (62.07%). The Kabyle goat is small (male: 62.23 cm and female: 58.41 cm) with long hair. Its ears are drooping, its convex profile has a slightly pronounced nasal split and its coat colour ranges from dark brown to black. However, the crossbreeding with exotic breeds (mainly with Saanen goat), controlled or uncontrolled, increased the frequency of white coat. The average age at puberty in males was 6.93 ± 1.04 and 7.38 ± 0.94 months in females. The reported age at first kidding and kidding interval were 13.03 ± 0.87 months and 7.83 ± 1.29 months, respectively. [less ▲]

This survey, conducted with 461 racehorse owners-breeders in Algeria between 2009 and 2011, 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 mating is here used to categorize breeders according to their degree of professionalization (38.4% professional vs. 61.6% occasional breeders). Experience in the sector was also used to classify breeders, considering as “junior” the breeders under 10 years experience (38.8%) and as “senior” those above 10 years (61.2%). More than professionalization, experience shows a significant impact on practices and objectives. Thus, experience influences breed choice (junior breeders tend to specialize while senior own both Arabian and Thoroughbreds), age at first foaling (sooner among senior breeders), information sources considered for selecting stallions (senior use more diversified sources), the importance granted to the price of mating (greater for junior breeders), the importance granted to the ranking compared to earnings (the ranking being more important to junior breeders), and the priority given to breeding (junior breeders give higher priority to a buy-race-resell activity). Finally, racehorse breeding is poorly professionalized, the only financial goal being cost coverage. Despite inappropriate practices, an interest for selection is noticed. [less ▲]

Despite its importance in Mali’s economy, camel breeding in the country remains poorly documented, impeding effective policy-making in this regard. This study consisted in a 3-month survey and aimed at characterising camel breeding systems in Ansongo, in the region of Gao, Mali. It highlights the diversity of strategies adopted by breeders and their evolutions. Supplementary feeding and veterinary care were seldom practised. In zones close to the Niger River, cattle were substituted to camels. Transhumance routes also are modified but mobility keeps its vital role in the breeding system. Important differences within the study region in the classification of camel breeds have been reported that will influence the implementation of a collective action for animal genetic improvement. The improvement goals should take the actual management, including mobility and the mixed nature of the herds into account. [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 ▲]

Quality variations in retail 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, 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). Egg weights differed significantly between marketing channels 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 shell thickness was similar for all marketing channels, the proportion of damaged eggs was higher in public markets (9.0%), intermediate in food shops (7.3%) and lower in supermarkets (5.7%; p<0.05). The yolk/albumen ratio was significantly higher for eggs from supermarkets (48.0%) compared with 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 with the two other channels (around 131 AD/kg; p<0.05). It is possible to conclude that egg quality in Bass Kabylie differs significantly among 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 ▲]

The Ardennaise breed is emblematic of the Belgian poultry diversity. We compared two varieties of the breed, the golden black and the silver black. The comparison encompassed: (i) the morphology of adult birds, (ii) the growth, carcass characteristics and meat quality of broilers 22 weeks old, (iii) the laying rate during 52 weeks and the egg quality. Significant differences were observed in the size of mature males and females: body weight, diameter and length of the tarsus, size of the comb and wattles. The two varieties did not differ concerning the carcass and meat quality traits. The golden black has a higher laying rate and a higher yolk / albumen ratio, but lays lighter eggs. It could be interesting to complete this study by molecular markers analysis to evaluate the degree of genetic diversity between the two varieties. [less ▲]
