This experiment was conducted to investigate the effect of plane of nutrition on body weight, average daily gain, dry mater intake, semen characteristics, serum testosterone concentration and testicular circumference of Sanjabi ram lambs during the natural breeding season. Sanjabi ram lambs (n = 20) that were 8 months of age were penned under natural photoperiod at latitude 34 º 18´ N for a period of 9 months. The control group (C, n = 10) received a diet consisting of 80% alfalfa and 20% concentrate, providing 2.18 Mcal metabolizable energy and 130.0 g/kg DM crude protein, whereas, treatment group (T, n = 10) was fed with 65% alfalfa and 35% concentrate, providing 2.34 Mcal metabolizable energy and 160.0 g/kg DM crude protein. Body weight, additive daily gain and feed intake in T group were significantly greater than those obtained in C group. Body weight and testicular circumference increased at a steady rate throughout the experiment. All semen variables (except percentage of abnormal sperm and semen pH), serum testosterone concentration and testicular circumference were positively influenced A C C E P T E D M A N U S C R I P T by nutritional state (P < 0.05). Interaction of nutritional state with season was found for semen volume, sperm concentration and abnormal sperm, but there was no interaction on the total sperm, progressive motility, live sperm, semen pH and semen index. It is concluded that the reproductive activity of growing Sanjabi ram lambs is affected by nutritional state. These results also demonstrated a monthly pattern in reproductive characteristices of Sanjabi ram lambs, independent of the nutritional state.
Current research studied the effect of two different dose of pomegranate peels powder 15 mg and w30 mg / week / head / on shami goat in iraq, with age 2 years and for the period from 12 -April - 2015 to 27-may ? 2015. Nine of shami goat in iraq divided randomly into three groups, as follows: control group which given tap water, second group given 15 mg/ week/ head and the third group given 30 mg/ week / head . Blood sample collected for measuring the concentration of Hemoglobin, and calculate the total number of red blood cells RBCs, and white blood cells WBCs. The weights of the three experimental groups measured at the start of the experiment and at the end of the experiment by scales used for large animals. The results show a significant increase (p<0.05) found in weight at the five week of the experiment. While there is no significant differences in the characteristics of blood, the study measured; (hemoglobin, RBCs number, WBCs number), while the level of Estrogen measurement end of the experiment. The second groups exceeded significantly(p<0.05) in level of estrogen 16.34?2.98(pg/ml).
PRODUCTIVE AND REPRODUCTIVE PERFORMANCE OF RAHMANI MALE LAMBS FED RATIONS CONTAINING JATROPHA CAKE
The objective of this study was to determine the effect of 70% Jatropha cake replaces by soybean on feedlot and reproductive performance of Rahmani male lambs. Following weaning the lambs were divided into two groups control and trial (n=8 in each). All groups were received concentrate and roughage as 60:40 ratios, respectively. The control lambs were fed concentrate feed mixture (CFM) plus berseem hay (BH). The trial lambs were nourished tested diet consisted of Jatropha cake instead of 70% soybean which contained CFM plus BH. Detoxification Jatropha cake by Lactic acid bacteria at rate of 1g/100 kg Jatropha cake. Measurements of live body weight, body weight gain and animal performances were calculated during five months as fattening period. The testicular characteristics were taken from 95 to 275 days and blood samples for testosterone hormone were started from 115 up to 275 days of age. Semen was collected by artificial vagina after lambs appeared 3 rd stage of puberty. The experimental result explained that values of live body weight, testicular diameter, testicular circumference, testicular length and testicular volume of ram lambs in Jatropha diet were higher than those in control diet. Moreover, results showed no significant differences among experimental rations on average daily gain. However, the highest average daily gain of growing lambs was recorded with Jatropha followed by control. The average daily total DM (g/h/d) intake of control lambs was 1250, but 1300 consumed by Jatropha lambs. The average daily gain (g/h/d) was rather in Jatropha lambs 204.6 than control lambs 199.3. The feed utilization efficiency was 10.14 % for Jatropha supplemented diet. The totally experimental measurements of lambs were affected positively (P<0.05) with advanced age during pubertal development. The lambs in Jatropha reached puberty earlier (241.45 days) than in control male (272.24 days). The Jatropha lambs were produced semen quality in higher (P<0.05) than those in control lambs. Jatropha groups had better (P<0.05) testosterone hormone concentration values than CFM group. It could be concluded that bacterial Jatropha meal could be replaced up to 70% of soybean meal in CFM without any adverse impact on body performance, puberty development and semen production of lambs.
Biometry and Testicular Growth Influenced by Nutrition on Prepubertal Pelibuey Lambs
The growth and testicular development was studied in 48 Pelibuey male lambs 76.6±3.0 days of age and 12.7±1.9 kg body weight (BW), two groups were designed (n=24). 1: Intensive rotational grassing (IRG), 2: Intensive rotational grassing plus nutritional supplement (IRGS). BW was recorded every 15 days from 75 days of age to the onset of puberty. The animals grazed on Panicum maximum. IRGS received a concentrate with 15% of protein. The testicular biometry included scrotal circumference (SC) and testicular volume (TV). Blood samples were collected each 15 days from 90 to 190 days of age for evaluate the testosterone concentrations. BW, SC and TV at histological puberty was higher in IRGS than IRG; 22.5±1.5 vs. 16.06±1.5 kg, 22.0±1.0 vs. 12.2±1.5 cm, 60.5±1.7 vs. 12±3.5 cm 3 respectively (P<0.05) with an average age for the two groups of 162±7.0 days. The correlation coefficient (R) was higher (P<0.05) for SC vs BW than age vs BW (0.884 vs 0.816) and the TV vs. BW than TV vs. age (0.849 vs. 0.777) in the IRGS; the IRG showed lower R for the same comparisons (P<0.05). Seminiferous tubules showed lumen by day 142, spermatids and spermatozoids by day 171 for IRGS, meanwhile in the IRG only showed gonocytes and Sertoli cells. Testosterone concentrations reached a peak (2.5 ng/ml) at 168 days of age for the IRGS meanwhile the IRG showed lower levels than 0.05 ng/ml. Testicular development and testosterone concentrations depends more on BW than age; and they are modified by the nutritional management in prepuberal male lambs.

The effect of feeding two maize (Zea mays) varieties (Quality Protein Maize [QPM] and common maize [BH540]) on testicular characteristics of ram lambs was studied in the indigenous Arsi sheep breed. The two maize varieties were fed in whole plant silage (WPS), earless silage (ELS) and stover (S) forms for a period of 12 weeks. Variables measured during the feeding trial were scrotal circumference, testicular diameter and scrotal skin thickness in live ram lambs and testicular length, width, height and epididymis weight after slaughtering. There were no conclusive findings with regard to differences between the two maize varieties (QPM and BH540) in supporting growth rates of testicular traits, yet the offer types (WPS, ELS and S) did appear to have an effect. Ram lambs fed on whole plant silage had shown the highest (P<0.001) scrotal circumference (28.1±0.3cm), scrotal circumference gain (0.45±0.03 mm/head/day), testicular diameter (5.77±0.09cm) and testicular diameter gain (0.13±0.01 mm/head/day) compared to the maize stover and earless silage fed groups. Testicular traits were positively and significantly correlated with each other (r = 0.73 to 0.95; P<0.001). The results suggest that the plane of nutrition influences testicular size. Whole plant silage feeding provided improved testicular size. Therefore, maize whole plant silage feeding might be helpful to improve the productive and reproductive performance of ram lambs.

The aim of this study was to investigate changes of serum testosterone, scrotal circumference, body weight, and semen characteristics in a Meat Institute Sheep (MIS) population during their developing period (between 3 and 17 months). Correlative relationships among parameters were also tested. Body weight and scrotal circumference were measured monthly, blood samples for testosterone levels were taken bimonthly (3-17 months), and semen samples were collected by an electroejaculator between the ages of 9 and 17 months. The analysis showed that the average serum testosterone levels ranged from 1.83 to 13.28 ng/mL and significantly depended on the age of the lambs (P < 0.05). The trend in the level of serum testosterone was characterized by pronounced variability throughout the study period. Changes in scrotal circumference and body weight were significantly dependent on age. Ejaculate volume, sperm motility, and the percentage of live spermatozoa increased with age, except for the percentage of abnormal spermatozoa, which decreased with age. Correlations among serum testosterone, scrotal circumference, and body weight were moderately to highly positive and highly significant. All parameters of semen quality were poorly correlated with testosterone and body weight, while scrotal circumference was in moderate correlation only with ejaculate volume and live sperm count (P < 0.05).
Growth Performance and Digestibility in Karadi Lambs Receiving Different Levels of Pomegranate Peels
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.
