fifteen holstein male calves (416 ± 35 kg initial bw; mean ± sd) were employed in a replicated 3 × 3 latin square test to investigate the effect of partial replacement of barley grain by wheat factory sewage (wfs) within three 22-d periods including 16 d of adaptation and 6 d of data collection. the basal diet (wfs0) consisted of 42.5% (dm basis) barley grain, partially replaced with either 23....

and Implications The effects of dietary energy sources in corn on the growth responses and carcass composition of high lean pigs fed from 55 to 110 kg body weight were evaluated. Low fiber composite corns were created by replacing the fiber in normal corn with isocaloric amounts of either corn starch or corn oil. Feeding the low fiber, composite corns reduced the amount of feed required per uni...

OBJECTIVE This study is to evaluate the anti-obese effects of glucosamine (GLC) and chitosan oligosaccharide (COS) on high-fat diet-induced obese rats. METHODS The rats were randomly divided into twelve groups: a normal diet group (NF), a high-fat diet group (HF), Orlistat group, GLC high-, middle-, and low-dose groups (GLC-H, GLC-M, GLC-L), COS1 (COS, number-average molecular weight ≤1000) h...

Angus, Hereford and Red Poll crossbred yearling heifers (n = 81) were mated to Brown Swiss bulls. Pregnant heifers were assigned on the bases of weight and breed cross to one of three diets and fed to achieve maternal weight gains of 0, .5 or 1.0 kg/d. Heifers from each treatment group were slaughtered at about 120, 150, 180, 210, 240, or 255 d postmating. Reproductive tracts were recovered at ...

Several studies have been conducted to determine the bioavailability of amino acids for young pigs in the 22 to 45 lb live weight range (Sato et al., 1987; Kovar et al., 1993; Adeola et al., 1994). Bioavailability assays based on animal performance provide relative information on the capacity of a feed ingredient to provide a specific limiting amino acid for maintenance and growth. Commonly use...

This study was conducted to evaluate the effects of replacing maize in quail diets with graded levels of rumen filtrate-fermented cassava meal (FCM) on growth and egg production performances. Cassava meal (CM) was mixed with dried manure of layer at 75 g/kg CM, which was mixed with freshly collected rumen filtrate (at 1 L/5 kg CM), and finally fermented in sealed bags for 14 days. It was then s...

Insulin-like growth factor 1 receptor (IGF-1R) is a main receptor of IGFs family which plays a critical role in the postnatal growth and skeletal growth in many species. However, there are few reports of IGF-1R gene structure and its effects on growth traits in sheep. The objectives of this study were detection of IGF-1R polymorphisms and assessment of their associations with ...

Twenty ®ve growing crossbred bulls (Bos indicus Bos taurus) were used in a randomised block design experiment for 196 days to determine the effect of grainless concentrate containing different supplemental nitrogen sources along with wheat straw based diet on feed intake, nutrient digestibility, plane of nutrition and daily live weight gain. The animals in control group received barley 30% in t...
