The current study was aimed to predict live weight and hot carcass weight from linear body measurements of yearling male local sheep. 84 days feeding period fortnightly taken data on 24 local sheep for body weight, body length, heart girth, wither height, sub-sternal height, tail length, tail width, scrotal circumference, and scrotal length were analyzed to study the relationship between linear body measurements and body weight. At the end of the trial all sheep were slaughtered to measure the relationship between body measurements, and hot carcass weight. Microsoft Excel 2010 was used for data analysis. The relationships between the various body measurements were calculated using pearson's correlation coefficient. The backward stepwise multiple regression procedure was used for the determination of the most suitable model for the prediction of the live weight and hot carcass weight. Hot carcass weight was highly correlated (P<0.01) with body weight and scrotal circumference. Besides, it was significantly (P<0.05) correlated with tail width. Body weight was significantly (P<0.05) correlated with all body measurements except tail length and scrotal length. It is concluded that the body weight of the local sheep can be predicted with heart girth, sub-sternal height and tail width; the equation is LW= -97.2 + 0.36HG + 2.1SBSH + 0.57TW with a better coefficient of determination; R 2 = 0.55 and the hot carcass weight can be predicted with sub-sternal height and tail width; the equation is HCW= -75.66 + 1.75SBSH + 0.85TW with a coefficient of determination; R 2 = 0.33. But, hot carcass can be predicted with body weight, the equation is HCW= -9.39+0.85BWT when weighing scales are affordable with a better coefficient of determination; R 2 = 0.557.

The rationale for supplementation of alfalfa hay with urea molasses block 1) high-producing animals protein need cannot exclusively met from rumen microbial sources; 2) protein is the most expensive nutrient of ruminant animal feed. Twenty-four yearling intact male local sheep with a mean initial body weight of 23.9±1.9 (M ean ± SD) were used in a completely randomized block design. Treatments were 1% of live weight alfalfa hay (1A), 1.5% of live weight alfalfa hay (1.5A), 2.0% of live weight alfalfa hay (2A), and all three treatments offered with 100g/head/day of Urea-molasses-block (UM B). The control treatment was supplemented with concentrate mix at 2.0% of live weight (C). In addition, all treatments were fed grass hay ad libitum. The study period consisted of 84 days of feeding and 7 days of digestibility tests. Total dry matter intake was 1015.65, 925.41, 956.16, and 1078.13 (SE=± 19.4) for C, 1A, 1.5A, and 2A, respectively and 1A was lower than 2A and similar with 1.5A and C. Apparent crude protein digestibility and Crude protein intake of 2A was statistically similar to C. But, higher than 1A and 1.5A. Average daily gain was 109.33, 54.76, 55.36, and 63.1 (SE=± 6.13) g/day for C, 1A, 1.5A, and 2A, respectively and the values were the highest for C. The study showed that concentrate supplementation at 2% body weight resulted in greater body weight gain, crude prot ein intake and apparent crude protein digestibility. Additionally, the weight gain achieved at all grade levels of alfalfa plus in combination with the same amount of urea molasses block was commendable. But, considering the accessibility and cost of conventional concentrate mixture, 2% of Live Weight Alfalfa hay with 100g/head/day urea molasses block is recommended as an alternative supplement regime for better sheep performance.

Twenty-four yearling intact male local sheep with mean initial body weight of 23.9±1.9 (Mean ± SD) were used in completely randomized block design.

The control treatment was supplemented with concentrate mix at 2.0% of live weight (T4). The study period consisted 84 days of feeding and 7 days digestibility trials.

Besides, dressing percentage (slaughter weight bases) was 43.55%, 44.6%, 44.53%, and 47.76% (SE=± 0.56) for T1, T2, T3 and T4, respectively and T1 was lowest and the values were similar among T2, T3, and T4 (p<0.05). The study showed that concentrate supplementation at 2% body weight resulted in greater hot carcass and primal cut weight than graded levels of alfalfa in combination with same amount of UMB. Additionally, the dressing percentage achieved at T2 and T3 was commendable. Therefore, T3 with good dressing percentage and biological performance can be considered as alternative supplement when concentrate is in short supply.
