We present a review of literature on the overview of the poultry sector in Vietnam. The review highlights main findings on poultry production and consumption trends, smallholder chicken production and productivity, and marketing of poultry products. It also summarizes the contribution of smallholder poultry production to household nutrition, the ro...

The content of intramuscular fat (IMF), that determines marbling levels is considered as one of the vital factors influencing beef sensory quality including tenderness, juiciness, flavour and colour. The IMF formation in cattle commences around six months after conception, and continuously grows throughout the life of the animal. The accumulation o...

This study aimed to investigate the effects of enzymatic antioxidants superoxide dismutase (SOD) and catalase supplementation on semen quality of multi-spurs chicken during liquid storage up to 48 h at 4oC. Pooled semen of twelve Vietnamese multi-spurred roosters was randomly divided into 7 experimental groups: control without supplement; SOD suppl...

This review provides an overview of the availability, nutritive value, and possible strategies to improve the utilisation of rice straw as a ruminant feed. Although, rice straw is the most abundant agricultural by-product and can consider as a sustainable source for ruminant feed in Vietnam, only a small proportion of rice straw is fed to ruminants...

Background and Objectives: Rice straw is the most abundant crop by-product in Vietnam, but research on fresh rice straw (FRS) silage is very limited. The objectives of this study were to investigate the effects of ensiling additives and durations on organoleptic characteristics and chemical compositions of FRS silage and to determine the suitable s...

The current review provides an overview ofomega-3 long chain polyunsaturated fatty acids (n-3 LC-PUFA) health benefits and the recent progress in using alpha linolenic acid (ALA) rich sources derived from oilseeds to enhance productive performance, n-3 PUFA profiles and sensorypropertiesof lamb for human consumption. In general, the supplementation...

We investigated the effect of various dietary polyunsaturated fatty acid (PUFA) sources on the fatty acid profiles of muscle, liver, heart and kidney of Australian prime lambs. Seventy-two White Suffolk x Corriedale first-cross lambs weaned at 6 months of age were randomly allocated to the following six treatments: (1) Control: Lucerne hay only; wh...

The correlations between growth and wool traits in response to canola and flaxseed oil supplementation were evaluated in Australian prime lambs. Sixty dual-purpose prime lambs including purebred Merino and crossbred lambs were allocated to one of five treatments of lucerne hay basal diet supplemented with isocaloric and isonitrogenous wheat-based p...

The Australian dairy sheep industry is small and mostly based on a natural grass grazing system, which can limit productivity. The current study tested different plant oil-infused and rumen protected polyunsaturated fats and their interactions with sire breeds to improve lactation traits and body condition scores (BCS) of ewes grazing low quality p...

The enhancement of health-beneficial omega-3 long–chain (≥C20) polyunsaturated fatty acid (n-3 LC-PUFA) contents in the muscle, liver, heart, and kidney of Australian prime lambs through pasture grazing and supplementation with oil infused pellets was investigated. Forty-eight first-cross prime lambs were randomly assigned into a split-plot design...

This study investigated live animal performance and carcass characteristics of Australian prime lambs fed oil based polyunsaturated fatty acid (PUFA) enriched pellets in a feedlot system. The tested hypothesis was that supplementation of lambs with a variety of dietary oil based PUFA enriched pellets would enhance growth and carcass characteristics...

This study investigated the effect of different plant oil-infused and rumen-protected wheat-based pellets containing eicosapentaenoic acid (EPA, 20:5n-3) and docosahexaenoic acid (DHA, 22:6n-3) on n-3 long-chain (≥C20) polyunsaturated fatty acid (LC-PUFA) content, fatty acid recovery, and sensory attributes of ripened cheese from dairy sheep. Durin...

In this report, an overview of the health benefits of omega-3 long-chain (≥C20) polyunsaturated fatty acids (n-3LC-PUFA) and recent progress in using alpha linolenic acid (ALA) rich sources derived from oilseeds to enhance productive performance, n-3 PUFA profiles and sensory properties of lamb for human consumption is reviewed.Omega-3 LC-PUFA can...

This study investigated the impact of supplementing dairy ewes in mid lactation with rumen‐protected (RPO) pellets containing eicosapentaenoic acid (EPA, 20:5n‐3) and docosahexaenoic acid (DHA, 22:6n‐3) or pellets infused with 50 ml/kg DM of either canola (CO), rice bran (RBO), flaxseed (FSO) or safflower (SFO) oils on enhancing the concentration o...
