This research analyzes the determinations of household land use strategy in the context of the rapid rural changes due to the industrialization and urbanization in Vietnam. The mechanism that turns land to livelihood from both productive and non-productive processes is investigated to understand the different land use strategies of smallholders in Red River Delta region. Based on the presence of migrating members, the total selected 191 households in Hai Duong province were divided into 3 different groups to do the surveys. The research results show that local land use strategies are various in which 79.06% of surveyed households maintain the allocated land for agricultural production while 65.97% of households leave land idly at least once a year. The factors from productive process such as small landholding, high production cost and overall downward income from agricultural production meantime the greater opportunities from non-farm jobs are the main socio-economical determinations of agricultural land abandonment or less effective use. The security questions of shifting livelihood between farming and non – farming sectors, the inter-household arrangements, the social supports and the institutional constraints are non-productive elements that make the exchange and other forms of commercializing agricultural land are less prominent. The complexity of household land use strategy and its determinations not only reflects the dynamism and flexibility of peasant’s livelihood adaptation but also explain why the land concentration does not proceed faster in Red River Delta region of Vietnam.

Economic evaluations of animal health surveillance systems are critical components of the assessment of their long-term sustainability and the improvement of their cost- effectiveness. Social costs and benefits of health information release through the surveillance systems are fundamental determinants of the acceptability and efficacy of surveillance and are often neglected in the evaluation process. This study presents the evaluation of social costs and benefits of Highly Pathogenic Avian Influenza (HPAI) surveillance in Vietnam. Three field studies were conducted in the South and North of the country. Data on animal health information flow networks and social costs and benefits were collected using participatory approaches. Non-monetary costs and benefits were quantified using a newly developed tool based on stated choice method and participatory techniques. The study showed that private actors incur many transaction costs in reporting the information. However social costs mainly arise from price drops due to information release on market which has strong influences on the decision to disclose sanitary information. This applies at all levels including farmers and veterinary authorities. Private actors of the poultry sector valued information on occurring disease outbreaks, which is perceived as a social benefit. However avian influenza information is scarcely disclosed in private networks as stakeholders fear its potential impact on markets. [less ▲]

This study was carried out at the animal farm of Hanoi University of Agriculture, Vietnam to evaluate the growth performance and meat quality of stress negative Piétrain pigs. The study concerns the body weight (BW) of 116 pigs at 7.5 months of age and the ultrasound measurements on 83 live animals in order to determine backfat thickness, longissimus muscle depth and lean meat percentage (LM). Meat color (C.I.E L*, a* and b*), peak shear force (SF), pH at 24h (pH24) and at 45 minutes (pH45) post mortem were measured on 31 meat samples. Meat chemical composition (dry matter, protein, lipids and ash) was determined on 23 meat samples. All the data were analyzed according to a linear fixed model including gender effect (female and intact males) and Halothane genotype (CC and CT). The interaction between gender and genotype was not observed and therefore it was ignored from the final model. The results show that BW and LM were not significantly different between genotypes (P>0.21) while females were heavier than males (101.11 vs. 93.85 kg, P=0.0011). LM of female and male were respectively 63.27 and 63.56%. Gender and genotype didn’t affect meat quality and chemical composition (P>0.05) except pH24 (P=0.0011), a* (P<0.0001) and lipids (P=0.0012) for gender effect. The pH45 (6.50 and 6.45 for females and males) and pH24 (5.34 and 5.49 for females and males) were in the range corresponding to a normal meat. The obtained results show that stress negative Piétrain pigs have high lean meat percentage and satisfactory meat quality under tropical climatic conditions in Vietnam. [less ▲]

The study was carried out on purebred nucleus herd of stress negative Piétrain pigs raised at Dong Hiep farm, Hai Phong province (HP) consisting of 18 males (13 CC and 5 CT) and 45 sows (31 CC and 14 CT) and at Animal farm of Hanoi University of Agriculture (HN), including 9 males (3 CC and 6 CT) and 21 sows (11 CC and 10 CT) from May 2010 in April 2013 to evaluate the effect of halothane genotype of boars (CC and CT) and halothane genotype of sows (CC and CT) on reproductive performance. The results showed that reproductive performance was not significantly different between boars CC and CT (P>0 .05). Body weight of piglets born from sows CT (1.54 kg) was higher than those from CC (1.42 kg) at birth, however at weaning this trend was opposite (6.46 kg vs. 6.00 kg). Reproduction performances of CC and CT boars were similar under opening and closing farm conditions. However, using of CC sows can improve the body weight of piglets at the weaning; in particularly, CC sows in the closing farm condition. [less ▲]

In Northern Vietnam, the livestock production sector has been strongly encouraged to develop by the government for many years as an important livelihood strategy to alleviate household poverty. Over the last few decades, it has been developed quickly, but remained unsustainable. This study aims to identify the dynamics of livestock production systems during the economic transformation period and their current constraints as the basic for setting up sustainable development policies. A survey, which is based on participatory and retrospective approaches, was conducted at 38 households in two communes of Hai Duong province in 2010. The results indicated a significant evolution of livestock production systems from a traditional small-scale production system into a specialized intensive one due to the land law and the rice land conversion program in 1990s and the industrialization and urbanization process in 2000s. The intensification of livestock production system, which is accompanied by the increasing dependence on imported inputs and the limited knowledge and skills in adequate techniques and disease management, poses a huge difficulty to producers in developing their livestock production systems. Therefore, the priority of development policies should be given to the promotion of the local resource utilisation as feed for animals and to the improvement of farmers’ ability to manage their production through not only government supports but also participation of social organisations and farmers.

The study was carried out at 3 pig farms in Hai Duong and Hung Yen from March 2011 to January 2013 to evaluate growth rate and carcass quality of F1(Landrace x Yorkshire) (F1(L x Y)) sows mated with F1(Piétrain x Duroc) (PiDu) boars with Pietrain ReHal genetic constitution (25, 50 and 50%: PiDu25, PiDu50, PiDu75). The results showed that these crossbreds obtained high growth rates and low feed conversion ratio (FCR) (829.42 g/day and 2.31 kg/kg; 797.78 g/day and 2.33 kg/kg; 765.79 g/day and 2.38 kg feed/kg weight gain, respectively). Lean meat percentage of PiDu25 x F1(L x Y), PiDu50 x F1(L x Y) và PiDu75 x F1(L x Y) were 54.66, 56.32 and 59.97%, respectively. Lean meat percentage of PiDu75 x F1(L x Y) was higher than that of PiDu25 x F1(L x Y) and PiDu50 x F1(L x Y). The meat quality traits in terms of pH, colour drip loss, and firmness of 3 crossbreds were normal. Crude protein of musculus longissimus dorsi of crossbreds was 21.53, 22.18 and 22.63%. The research suggests that using crossbed boars PiDu25, PiDu50, PiDu75 to mate with F1(L x Y) sows helps to obtain high performance in pig farms [less ▲]

This study was carried out on 10 stress-negative Piétrain boars including 3 pigs of halothane genotype CC and 7 of CT at the pig breeding farm of Hanoi University of Agriculture in order to evaluate effects of season (Spring, Summer and Autumn) and halothane genotype (CC and CT) on the production performance and semen traits. The results showed that the difference in daily average gain was not significant between CC (559.57 g/day) and CT boars (546.31 g/day). The halothane genotype did not affect semen traits (P>0.05) except ejaculation volume (P<0.001). Ejaculation volume of CC genotype (270.95ml) was higher than that of CT (220.82ml). Season had significant effect on ejaculation volume, sperm concentration and pH of semen (P<0.001) as well as total number of sperms moving straight ahead per each ejaculation (P<0.05). Semen volume was highest in autumn (293.02 ml) followed by summer (195.00 ml) and spring (190.86 ml) while this tendency was inverse for sperm concentration. Total number of sperms moving straight ahead per each ejaculation was highest in Autumn (47.15 billion) followed by Spring (45.20 billion) and lowest in Summer (36.74 billion). Semen traits of the stress-negative Piétrain boars were in accordance to the standards of technical criteria for animal breeding accoprding to the DecisionNo. 1712/QĐ-BNN-CN (Ministry of Agriculture and Rural development, Vietnam), except sperm motility and growth performance were lower than specified.

A study was carried out from December 2011 to August 2012 to evaluate reproductive performance of nucleus herd of stress negative Piétrain (Piétrain) and Duroc pigs raised at the experimental farm of Hanoi University of Agriculture. A total of 35 gilts, including 21 Piétrain (11 with halothane genotype CC and 10 with CT) and 14 Duroc CC gilts were monitored for their reproductive performance. Piétrain boars (3 CC and 5 CT) were mated to Piétrain and Duroc gilts to produce Piétrain purebred and crossbred Piétrain x Duroc pigs. Results showed that genotype of the boar and the sow affected body weight and litter weight at birth and at weaning (P<0.05). Total number of pigs born, number born alive, number alive to weaning, individual bodyweight at birth, individual bodyweight at weaning, litter weight at birth, litter weight at weaning, survival rate at birth, survival rate to weaning were 9.91, 9.26, 8.11 piglets, 1.4, 6.4, 12.97, 51.96kg, 94.32 and 88.55%, respectively. Body weight and litter weight at birth and at weaning of piglets from Piétrain CC boars were higher than those of piglets from Piétrain CT boars (P<0.05). Reproductive performance was highest for Duroc CC sows, followed by Piétrain CC and lowest for Piétrain CT sows (P<0.05). Reproductive performance of the nucleus herd could be improved by using Piétrain CC boars mated to Piétrain CC sows and Duroc CC sows. [less ▲]

The presence of antibacterial in 97 pork and 83 chicken meat samples, randomly collected from 3 different representative provinces (Hanoi, Hai Duong and Thai Binh) of the Red River Delta, was determined by a screening step using in parallel 2 microbiological methods (Premi®-test and New Two Plate Test). In total, 27% of all samples displayed a positive response in at least one of both tests, from which 11 (13% of chicken samples) are chicken samples and 38 (39% of pork samples) are pork samples. The 33 samples from the Thai Binh which were screened positive were then submitted to post-screening tests specific for tetracyclines and (fluoro) quinolones (Tetrasensor® dipstick for tetracyclines and an ELISA for quinolones), two groups of antibiotics widely used in animal production in this region, and confirmed by liquid chromatography coupled to mass spectrometry. Tetracyclines and (fluoro)quinolones residues were found, using a post screening test, in 23 and 5 samples, respectively. Ten (all pork) and 4 samples (1 pork, 3 chicken) were confirmed containing tetracyclines (chlortetracycline, oxytetracycline, tetracycline, doxycycline) and (fluoro) quinolones (nalidixic acid, enrofloxacin and ciprofloxacin) respectively, from which 1 and 3 pork samples were found to contain enrofloxacin and tetracycline residues , respectively, with a concentration higher than their respective MRLs. This study shows the good performance of the proposed strategy to identify non-compliant meat samples (microbiological screening, tetracyclines and quinolones targeted post-screening and confirmation), which allows to obtain conclusive results in 82% of the cases.

In Vietnam where epidemics occur regularly in animal production, the farmers consider antibiotics as one of the solutions to fight against livestock diseases, thus the risk of abuse, even illegal use of antibiotics in livestock is very high. However, this is a recent issue and has not yet been thoroughly investigated. A cross-sectional study on the use of antibiotics in pig and poultry production as well as the farmer’s knowledge on the danger of the antibiotic use in three different animal production systems (farm household, semi-industrial and industrial) was conducted from July 2009 to March 2010 on 270 entities, in 3 representative localities of the Red River Delta (RRD). The results showed that a large volume of antibiotics was used arbitrary in all animal production systems. Animals were not only treated for acute diseases, but also for disease prevention, and for growth promotion. At least 45 antibiotics of more than 10 classes were used. Fifteen antibiotics were used in pig and poultry feed. For diseases treatment and prevention, antibiotics were used abusively and even illegally (e.g. chloramphenicol) by both farmers and veterinarians. The findings of this survey will permit developing new strategies for prudent use of antibiotics in livestock in Vietnam. These results will help not only to strengthen issues such as veterinary networks; antibiotics use guidance, residues monitoring systems and food safety, but also to improve awareness and ethics of producers and veterinary drug sellers.

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 ▲]
