Because wheat forage contains high concentrations of N, NPN, digestible DM, and water, beef cattle and sheep require an adaptation period before positive BW are seen. The objective of the present experiment was to determine the impact of length of exposure of lambs and steers to wheat forage on BW gains, N retention, and forage digestibility. Sixteen steer calves (average BW = 210 +/- 12 kg) an...
the effects of different levels (0, 10, 20 and 30 percentage of dry matter) of apple pomace ensiled with urea were investigated on 24 ghezel male lambs in a completely randomized design with four treatments and six replicates. the average starting weight and age of the lambs were 31.27 ± 7.40 and 187 ± 37 days, respectively. after 15 days of adaptation, the lambs were individually fed with expe...
OBJECTIVE The objective of this study was to evaluate the intake and nutrient digestibility, nitrogen balance and ruminal ammonia nitrogen in lambs of diets containing different levels of residual frying oil. METHODS Levels of 0, 20, 40, 60, and 80 g/kg dry matter (DM) base of residual frying oil in the diets of lambs were evaluated. Five castrated lambs with initial body weights of 36.8±3.3 ...
The aim of this study was to evaluate the effect sex on fattening performance and carcass characteristics Kivircik lambs. Fifty head weaned lambs, half males females, were used in period. After weaning, growth feed consumption male female lambs fattened for 56 days recorded. Average daily weight gain differed significantly (P
An experiment was carried to evaluate the effects of gender and two dietary ionophores on growth performance and slaughter characteristics in Moghani sheep. A total of 30 Moghani lambs (15 males and 15 females) were distributed randomly into 30 individual cages. Each gender group consisted of 5 animals and fed with a basal diet with no supplement, the same basal diet plus 25 mg/kg monensin (MON...
Diets with low forage concentration may depress feed intake and average daily gain, while diets with high forage concentration may limit feed intake due to rumen filling. Adequate forage level may range from 7% to 14% in ration for feedlot lambs, depending on forage source and ingredient composition. Small amounts of good quality forage may improve growth performance of sheep in the first stage...
The objective of this study was to investigate the effect of maintenance system as well as the effect of Se, Zn, and vitamin E supplementation of ram-lambs on the slaughter value and concentration of mineral elements in the loin muscle of lambs. The experiment was conducted on 72 Polish Merino ram-lambs divided into three groups: group C, indoor with no supplement, 19 lambs; S, indoor with supp...
This study aimed to investigate the effect of the ratio of non-fibrous carbohydrates to neutral detergent fibre (NFC/NDF) and undegraded dietary protein (UDP) on rumen fermentation and nitrogen metabolism in lambs. Four Dorper×thin-tailed Han crossbred lambs, averaging 62.3±1.9 kg of body weight and 10 mo of age, were randomly assigned to four dietary treatments of combinations of two levels of...
Twenty-four Merino lambs (mean BW 15.4 ± 0.13 kg, 6 to 7 wk old) were used to study the effects of the addition of 0 (control), 100 (V10), and 200 (V20) g of vinasse per kilgram of concentrate on intake, animal performance, biochemical blood profile, and carcass and meat characteristics. Lambs were assigned to 1 of 3 experimental diets and fed barley straw and the corresponding concentrate ad l...
I . The metabolism of tritium-labelled tocopherol was investigated in thirty-six wethers and forty-two ewes fed on hay known to produce nutritional muscular dystrophy (NMD). 2. In one experiment, the effect of selenium or vitamin E or both on the metabolism of tritium-labelled tocopherol was studied. No difference was found in the incorporation rate of radioactivity in tissues due to the additi...
