Estimating the non-commercial-commercial feed gap in China and its impact on future world demand for soybeans
… on meat consumption and the transition effect on feed usage in animal production. The income effect has been studied intensively by previous researchers, and more animal products are believed to be consumed. The transition effect, however, has yet received enough attention. This study shows that …

Strategies to maximize feed quality and poultry performance
… in nature and may be directly implemented in the commercial poultry industry to improve production. Many commercial feed mills utilize low mixer-added fat (MAF) to increase ingredient binding opportunities and pellet quality, but this technique may decrease feed nutrient digestibility. In Chapter …
