OBJECTIVE
In order to assess the safety of genetically modified crops, the anti-nutrients were determined in these novel crops and compared with their parental lines.
METHODS
Five kinds of crops (rice, maize, soybean, cottonseed and rapeseed) from domestic and foreign companies were collected and
OBJECTIVE
This study was conducted to evaluate the effects of dietary protein sources (soybean meal, SBM; low-gossypol cottonseed meal, LCSM; double-zero rapeseed meal, DRM) on laying performance, egg quality, and plasma parameters of laying hens.
METHODS
A total of 432 32-wk-old laying hens were
The aim of this study was to evaluate the effect of different protein ingredients on performance, egg quality, organ health, and jejunum morphology of laying hens. A total of 216 32-wk-old Hy-Line W36 laying hens with similar egg production was randomly divided into 3 treatment groups with 6
Digestibility of protein in traditional diets from developing countries such as India, Guatemala, and Brazil is considerably lower compared to that of protein in typical North American diets (54-78 versus 88-94%). The presence of less digestible protein fractions, high levels of insoluble fiber, and
Protein sources are the second most important component in poultry diets. Due to the fluctuation in price of soybean meal (SBM) and persistent increase in feed prices, nutritionists have been exploring alternative protein sources. Replacement of SBM with alternative protein sources in poultry diets
