The objective of current study was to determine the effect of different ratios of pomegranate peel in diets of Karadi lambs (0%, 1%, 2% or 4% as control, T1, T2 and T3, respectively) on body weight, total body gain, average daily gain, daily feed intake and apparent digestibility of nutrients. Sixteen Karadi male lambs weighing 23.29 ± 0.42 kg and 4.5-5 months old randomly divided into equally four treatment groups and individually penned for the period of 63 days. Results indicated that final body weight was significantly (P < 0.05) higher in lambs fed 1% or 2% pomegranate peel (PP) as compared to lambs fed 4% PP. The best improvements in total feed intake, total gain, average daily gain and feed conversion ratio (FCR) in lambs fed 1% PP. The total dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), ash, nitrogen free extract (NFE) and metabolizable energy (ME) intake per (body weight 0.75) increased (P < 0.05) significantly in lambs fed 1% pomegranate peel (PP); however, the crude fiber (CF) intake decreased in lambs fed 1% PP as compared to other treatments. While, the dry matter digestibility (DMD), crude protein digestibility (CPD), crude fiber digestibility (CFD) and nitrogen free extract digestibility (NFED) were significantly (P < 0.05) higher in lambs fed 1% PP as compared to T2, T3 and control groups. In addition, EED increased significantly in T3 compared to other treatments. In conclusion, it was indicated that addition of pomegranate peel in diet at the rate of 1% or 2% had significant effect on Karadi lambs performance and digestibility.

This study was carried out to evaluation the effect of slaughter weights on carcass characteristics and meat sensory evaluation of Karadi male lambs. A total 20 male Karadi lambs, with an average initial body live weight of 23.27 ± 0.28 kg and 3 to 4 months old were used in this experiment. Lambs were randomly allocated to 4 groups (5 lambs for each group). The experimental diet was consisting of concentrate feed 75% and 25% of wheat straw and prepared based on Cornell net carbohydrate and protein system software for growing lambs. Lambs were slaughtered according to Islamic way when each lamb has reached its target slaughter weights of 28, 33, 38 and 43 kg for treatments (T1, T2, T3 and T4), respectively, following fasting for 12 h, with free access to water. The slaughter weight (SW), empty body, hot and cold carcass weights were all significantly different (p≤0.05) among all treatments. The foreshank was significantly (p≤0.05) difference between T1 and T3, while T2 and T4 were not significant. The physical dissection of shoulder for (fat and bone) and foreshank for (meat, fat and bone) were significantly differences (p≤0.05) among treatments. The percentage of meat in neck were significantly differences (p≤0.05) among treatments. Fat thickness and sensory evaluation for (tenderness and juiciness) were significant differences (p≤0.05) among treatments. It was concluded that the Karadi male lambs slaughtered at weights between 38-43 kg improved carcass characteristics, physical dissection, carcass cuts and some sensory evaluation of their meat.

The effect of a liquid methionine source provided through the drinking water on broiler chick performance, water intake, and carcass characteristics were studied using 264 unsexed broiler chicks (Ross 308, 7 days old). Methionine was added within three replicates in four treatments with 22 birds in each as follows: T1 (control treatment): without adding liquid methionine, T2: adding 0.25 ml of liquid methionine/litter of drinking water, T3: adding 0.50 ml of liquid methionine/litter of drinking water, and T4: adding 0.75 ml of liquid methionine/litter of drinking water. Live body weight, body weight gain, feed intake, feed conversion ratio, water intake, and carcass traits were taken. The results showed that adding liquid methionine in drinking water were significantly increased (P≤0.05) live body weight, total feed intake, and body weight gain, as well as carcass traits also were significantly different among the treatments. Within the limits of the study, liquid DL-methionine provided in the drinking water was effectively assimilated by broiler chicks and increased total methionine intake, which increased the growth rate of the chicks.
