Growth performance, feed conversion efficiency and nutrient utilization of mutton synthetic, selected and randombred Malpura populations of lambs (60days) were evaluated. The mutton synthetic lambs reached the 25kg body weight in 73days of intensive feeding while the selected and randombred Malpura populations of lambs reached the same weight in 91 and 136days, respectively (P<0.01). The fitted...

other energy depots can be forced, however, genetic associations may remain when phenotypic regression is used. Heritability estimates for phenotypic residual feed intake have been moderate, ranging from 0.26 to 0.43. Genetic correlations of phenotypic residual feed intake with feed intake have been highly positive, suggesting that improvement would produce the correlated response of decreasing...

Pigs were weaned at 16 to 20 days of age and fed diets containing either dried whey or 6% dried porcine solubles (DPS), partially replacing dried whey protein, and one of two combinations of feed additives (either ZnO + CSP 250 or CuSO4 + Mecadox) in a 2 × 2 factorial arrangement. The diets were fed for 2 weeks and followed by a common diet for 3 weeks. Feeding the DPS-containing diet during we...

Feed represents the greatest single expenditure associated with poultry production. nutritional research in poultry has therefore centred on issues related to identifying barriers to effective digestion and utilization of nutrients, and on approaches for improving feed utilization. Poultry nutritionists have increasingly combined their expertise with that of specialists in other biological scie...

The objective of this study is to characterize the influence of immune stress induced by lipopolysaccharide (LPS) on protein utilization and turnover for early-weaned pigs. A total of 15, crossbred weanling pigs (initial body weight 10.15±0.39 kg) were assigned to one of three treatments. Pigs were injected with LPS and fed ad libitum (LPS-challenge), or injected with endotoxinfree physiologica...

with the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. the novel concept of photovoltaic powered ...

For the request of rational and scientific farming of dairy cow, the database of dairy cow’s feed composition and ratio is established, and the feed formula service management platform and transaction processing platform is realized in Science Feed Management System. The application of this system contributes to improve science of dairy cow’s feed formula, enhance the utilization of the raw mat...
