This study was conducted in the animal field that belongs to Animal Resource Dept.,College of Agriculture and Forestry,Mosul University. Sixteen local males lambs were used at the began of fasting process with age about 7-8 months and initial weight average 38.200 kg , were divided randomly into four groups and then distributed randomly into four treatments. The treatments consisted of differen...

The behaviour of 3-week weaned pigs in different housing systems was examined as part of an assessment of the suitability of the Straw-Flow(R) system for pigs of this age. Three replicate pens of 20 pigs were weaned at 6.4 kg liveweight into each of: (a) deep-straw; (b) Straw-Flow(R); (c) large flatdeck; (d) small flatdeck. A kenneled lying area was provided in (a) and (b). The floor in (c) and...

Ninety-nine uncastrated males were randomly distributed into four grazing groups to examine variation in growth and carcass traits, due the implant regime [Implantation of 72 miligrams (mg) Ralgro® at day (d) 0 followed by its reimplantation d 90 versus implantation Revalor® mg 90)], suplementation type [mineral supplementation (MS) strategic (SS)]. With a 2 x factorial arrangement, analysis va...

Muscling in cattle is largely influenced by genetic background, ultimately affecting beef yield and is of major interest to the beef industry. This investigation aimed to determine whether primary skeletal muscle cells isolated from different breeds of cattle with a varying genetic potential for muscling differ in their myogenic proliferative capacity. Primary skeletal muscle cells were isolate...

Replacement of skim milk proteins by solubilized wheat protein (SWP) in milk replacers for veal calves would contribute to the reduction in feeding costs. The occurrence of metabolic disorders has, however, been reported. Forty-two male calves received one of three treatments over 140 days: a control diet, a diet containing SWP without or with branched-chain amino acid supplementation. Liveweig...
