In order to investigate the effect of surplus jujube meal with or without Rovabio enzyme on growth performance, carcass traits and ileum morphology in broiler chicken; 320 male broiler chicks of Ross 308 were assigned to eight treatments, four replicates and 10 birds per each. The treatments included four levels of surplus jujube meal (0, 4, 7 and 10 percent) and two levels of Rovabio multi-enzyme (0 and 0.1 percent). The data were analyzed based on completely randomized design in factorial arrangement (2×4). The results showed that the birds fed diet containing 10% jujube with enzyme had a higher feed intake in the grower, finisher and whole periods as compared to control (no jujube and enzyme treatment; P<0.05). The main effect and interactions of enzymes and jujube had no effect on weight gain and feed conversion ratio. However, in the starter period when the birds fed diet contained 10% jujube along with enzyme, a higher weight gain than control was observed (P<0.05). Supplementation of 4% Jujube with enzyme increased the percentage of breast and the level of 7% jujube reduced abdominal fat compared to control (P<0.05). Compared to control, the birds fed diets containing 10% jujube with the enzyme had higher and lower villus height and width respectively (P<0.05). The ratio of villus height to crypt depth was the highest in birds fed enzyme (P<0.05). It is concluded that adding 10% of jujube to the diet of broiler chickens and supplementing it with enzyme could improve the performance and meat quality of broiler chicken.

Abstract
To evaluate the effect of type (Rice Hull (RH) and Oat Hull (OH)), level (3 and 6 percent) and particle size (0.5 and 2 mm) of insoluble fiber on performance, carcass characteristics and intestinal morphology of chickens, 360 day-old male broilers (Ross 308), were use in a completely randomized design ...

To evaluate the effect of type (Rice Hull (RH) and Oat Hull (OH)), level (3 and 6 percent) and particle size (0.5 and 2 mm) of insoluble fiber on performance, carcass characteristics and intestinal morphology of chickens, 360 day-old male broilers (Ross 308), were use in a completely randomized design with 9 treatment and 4 replicate with 10 birds each, for 42 days. In the 29-42 days, broilers fed 6 percent with 0.5 mm RH had higher (P≤0.05) average daily gain, daily feed intake and lower feed: gain than control group. In fact, the 6 percent with 0.5 mm OH inclusion reduced (P≤0.01) abdominal fat and carcass performance as compared to control (P≤0.0`5). Results showed that broilers fed OH and RH had higher relative weight of gizzard and gallbladder than broilers fed the control diet (P≤0.05). Broilers fed RH had higher villus length than other treatment in the jejnum at 21 and 42 days of age and duodenum at 21 days of age (P≤0.01). In this experiment, the broiler fed 3 percent RH with 2 mm particle size had the highest epithelium width (P≤0.01) in the ileum section at 21 day of age. Therefore the results showed inclusion of 3 percent RH with 0.5 mm particle size to broiler diets may improve the growth performance and intestine morphology.

This study was conducted to evaluate the effects of replacing soybean meal with hempseed meal in diet on performance, egg quality and blood parameters in laying hens. A total of 200 Hy-line 102 wks laying hens were randomly allotted to 25 cages in 5 dietary treatments with 5 replicates (8 birds each replicate). This experiment was conducted in a completely randomized design with 5 treatments involved different ratio of soybean meal to hempseed meal protein source including 1) ratio of 100: 0 protein of soybean meal to hempseed meal (control); 2) ratio of 75: 25 protein of soybean meal to hempseed meal; 3) ratio of 50: 50 protein of soybean meal to hempseed meal; 4) ratio of 25: 75 protein of soybean meal to hempseed meal; and 5) ratio of 0: 100 protein of soybean meal to hempseed meal. Egg production, egg mean weight and feed intake in the birds fed diet contained ratio of 0: 100 protein of soybean meal to hempseed meal were higher than control diet (P<0.05). Albumin height (Haugh unit), yolk color index, yolk weight percentage and shell weight percentage were ameliorated when hens fed diets the highest protein ratio of hempseed meal compared with the control group. Using hempseed meal in diets decreased (P<0.05) the cholesterol, triglycerides and lipoprotein with low density as compared with the control group. It can be concluded that replacing of 75 % and 100% of hempseed meal to soybean meal may improve the performance, egg quality of post molting layer and decrease the serum LDL and cholesterol of laying hens.

The present experiment was conducted to determine metabolizable energy of pomegranate peel and pulp by adult cockerels. The pomegranate peel and pulp samples were gathered from three industries. This study had two experiments. Each experiment was done in a completely randomized design with 4 treatments and 4 replicate (1 cockerel each). The cockerels fed conventional addition method (CAM). The data were revealed that the pomegranate pulp had 91.18-93.41% dry matter (DM) 4.04-4.28 % crude proteins (CP), 1.38-1.72% ether extract (EE) and 15.48- 19.21% crude fiber (CF) and 4.62% ash. The apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), true metabolizable energy (TME) and nitrogen-corrected true metabolizable energy of pomegranate peel were 2219.84-2443.21, 2201.09-2424.13, 2250.13-2482.69, and 2249.56, 2481.56 kcal/kg, respectively. The pomegranate pulp had 91.07-92.63% DM, 10.21-11.80% CP, 9.72-10.83% EE and 31.51-35.94% CF. The apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), true metabolizable energy (TME) and nitrogen-corrected true metabolizable energy of pomegranate pulp were 2357.71-2581, 2355.83-2579.2, 2452.62-2642.93 and 2451.11 -2641.52 kcal/kg, respectively. The estimated AMEn of pomegranate pulp and peel based on prediction equation were 2419.19-2540.8, 2166.02-2533.67 kcal/kg. The best eqution for estimating of AMEn were Nascimento, AMEn = 2707.71 + 5.863EE− 1.606aNDFom. It is concluded that the pomegranate pulp may had a good feed to use in poultry diet, but the manager may be consider the tannin and other anti-nutrition factor in pomegranate.
