effects of replacement of barley grain with corn grain on fattening performance of male

چکیده
this project was conducted to evaluation the effects of replacement of barley grain with corn grain on fatteningperformance of male lambs. twenty five male lambs (6-7 month-old, average body weight = 31.22 ± 3.4 kg) were assigned randomly to five dietary treatments (5 lambs/treatment) in a randomized complete design. the first diet contained barley grain without corn grain but in the other diets from two to five corn replaced barley 25, 50, 75 and 100%, respectively. the tmr rations provided in pellet form. the results showed that dm and me intake were not affected by the experimental diets (p>0.05). average feed conversion ratio was not affected by the increasing replacement of barley with corn (p>0.05). the average live weight gain and average daily gain were not significant (p>0.05). feed cost ($/kg weight gain) and return on investment were not affected by the experimental diets but cost per unit production was the lowest for lambs fed the diet contained 50% corn grain (p<0.05). on the basis of this study corn grain can be replaced with barley grain in lamb fattening diets without any additional cost

Effects of Barley Grain Particle Size on Ruminal Fermentation and Carcass Characteristics of Male Lambs Fed High Urea Diet
Two experiments were conducted to evaluate effects of barley grains particle size on ruminal pH and ammonia concentration of rams (experiment 1) and carcass characteristics (experiment 2) of male lambs fed high urea diet. Treatments in two experiments were (1: basal diet + whole barley grains, 2: basal diet + ground barley grains with a 5 mm screen, 3: basal diet + ground barley grains with a 3...
