Effects of Stocking Density in Group Cages on Egg Production, Profitability, and Aggressive Pecking of Hens.

There is an increasing concern about welfare issues related to battery cages, which are commonly used in Vietnam, and requires a modified cage that improves hen welfare while retaining its economic and management advantages. We combined adjacent conventional cages to form group cages to examine the effects of stocking density on egg production, economic returns, and aggressive pecking of hens. The control group included triplicate conventional cages with four birds/single cage (12 hens per three cages) or 450 cm area per hen.

Mapping the pork value chain in Vietnam: a systematic review.

In Vietnam, pork is the most commonly consumed type of meat, and the demand is expected to rise even further. Nevertheless, food safety is a major concern, as the country bears a high burden of food-borne diseases, including these caused by pork products. Knowledge of the flows of pigs and pork from producers up to the consumers is important; however, up to now, a comprehensive overview is lacking.

Incentive mechanism to promote corn stalk return sustainably in Henan, China.

Corn stalk return (CSR) can manage agricultural residues on the spot to avoid field open burning and protect the environment. However, the implementation of this measure encounters reluctance from farmers which hinders its sustainability. This study combined the economic (cost) and technical (return amount, crushing quality, and decomposition of corn stalk) aspects to examine the factors affecting farmers' willingness to participate in the CSR by using a logistic regression model.
