The Optimum Energy Density in Diets for Lori-Bakhtiari Lambs during a Fattening Program
Forty growing ram lambs (Lori-Bakhtiari breed) averaging 28 kg (±1.5) were allocated in this study to evaluate the optimal dietary energy density in a lamb fattening enterprise in Iran. The feed intake (FI), body weight (BW), gain to feed ratio (G:F) and carcass characteristics were studied. Four treatments differed in metabolizable energy content (ME) as follow; 2, 2.3, 2.6 and 2.9 Mcal/kg for...
متن کاملEffect of Diets with Different Forage to Concentrate Ratio for Fattening of Lohi Lambs
The objective of this study was to determine the effect of different forage to concentrate ratios for fattening of Lohi lambs. For this purpose, 75 lambs were randomly divided into 3 groups A, B and C, with 25 lambs in each group. Berseem fodder was supplemented with concentrate at different ratios (forage to concentrate) as 75:25, 50:50 and 25:75 and fed to groups A, B and C, respectively for ...

متن کاملLimiting amino acids for growing lambs fed a diet low in ruminally undegradable protein.
Ruminally cannulated Rambouillet wether lambs were used in three 6 x 6 Latin square experiments (n = 6/experiment) to determine which essential AA limit N retention. Lambs (BW = 36.9 +/- 1.9 kg for Exp. 1, 35.1 +/- 1.4 kg for Exp. 2, and 46.0 +/- 1.3 kg for Exp. 3) were housed in metabolism crates and limit-fed (DMI = approx. 1.8% of BW daily) twice daily a soybean hull-based diet low in rumina...
متن کاملMilk Yield and Blood Metabolite Profile in Late Pregnancy in Lori Ewes Receiving Diets Containing Undegradable Protein Sources
An experiment was conducted to investigate the effects of supplementing Lori ewes with rumen-undegradable protein (RUP) in late pregnancy on their performance and that of their lambs. Milk yield and blood metabolite profile were measured. Forty pregnant ewes were used in a completely randomized design trial with four treatments: 1) a basal diet (control); 2) with a supplement of 5% fishmeal; 3)...
