An experiment was conducted from 18th October, 2006 to 18th January, 2007 at IAAS Livestock Farm, Rampur, Chitwan to determine the substitution effects of soybean meal with brewer’s dried grain (BDG) on the performance, economics and meat traits of swine production. Starter, grower and finisher diets were formulated containing 18, 16, and 14% CP respectively with 3000 Kcal/kg ME and adequately ...

In this study, we developed a model of sperm in vitro differentiation to study the mechanism of spermatogenesis. We isolated newborn male germ cells for in vitro differentiation. We found that after 4-5 weeks of culture, sperm-like cells were occasionally observed in cell co-culture and the feed-layer. After 1-2 weeks of culture followed by 4-5 weeks of co-culture, sperm-like cells were observed.

the expansion of aquaculture in the last 10 years has made it an important source of protein worldwide.  however, increased production, and the culture intensification it carries, results in higher risk of infectious disease due to poor water quality and high stocking densities. disease has several negative effects on fish, which include reduced feed efficiency, impaired growth and death, repre...

The study examined the growth performance of pigs offered liquid feed or dry feed on either a restricted or an ad libitum basis, and whether their growth performance was further influenced by the water-to-feed ratio. The study was split into two parts to enable unrestricted (trial 1; n = 64) and restricted (trial 2; n = 48) feeding to be compared. Male pigs were randomly allocated to six dietar...

Although the feed-conversion ratio is recognized as a prominent indicator of profitability for pork producers, only 212 (50.7%) of 418 producers who were asked the feed-conversion ratio for finisher pigs provided a response during the USA National Animal Health Monitoring System 1995 National Swine Study. Of these, 126 (59.4%) producers furnished a feed-conversion ratio which they characterized...

  To determine the best live food and to reevaluate the optimal weaning period for beluga fish (Huso huso) larvae, seven experimental diets: Daphina (DP), Chironomids (CH), Gammarid (G), Daphina + formulated diet (DPFD), Chironomids + formulated diet (CHFD), Gammarid + formulated diet (GFD ) and formulated diet (FD ) in triplicate groups were fed to 4662 sixteen-days-old larvae which were captu...
