Rahmani ewes (n=25) were used to investigate the effect of subcutaneous back fat (BF), body condition score (BCS), body weight (BW) and age on their follicular dynamics. Ewes were estrus synchronized using 2 doses of Cloprostenol 11 days apart. At the second dose, ultrasound was used to count follicles and measure their diameter for 5 successive days and counting corpora lutea 7 days after ovulation. Ultrasound also was used to determine BF parallel to the last thoracic vertebra. There is a significant increase in number of large follicles on the left ovary with the increase of back fat. Ewes with BF ≥1.5 mm have low medium follicles but high large follicles on their left ovaries and high large follicles and dominant follicles diameter on their right ovaries. The increase in back fat thickness was accompanied by a significant increase in ovulation rate (OR). Large follicles, total follicles and ovulation rate are low in ewes with back fat thickness 1mm and good body condition >2 and to delay those of low subcutaneous fat < 1mm and body condition <2 till they gain enough body reserves to result in an economically viable return from sheep flocks.

The two studies reported performance of Rambuoillet crossbreds (ewes and rams) with local sheep breed Khutta under grazing system of transhumant. Analysis of variance revealed that Rambouillet crossbred ewes were initially 16 percent heavier than their age mates of local breed. Within each genotype, ewes <1 year old were significantly (p<.01) lighter than >1, >2, >3 and >4 years old. Although Rambouillet crossbred ewes were 17 percent heavier, pattern of differences in BW of various age groups of both genotypes at the start of movement for grazing toward alpine pastures of northern areas (First recording) was almost the same. However ewes of local genotype-Khutta lost more BW (6.7 kg) during movement back to low land areas (Second recording) compared with Rambouillet crossbred ewes (4.1 kg). BW of Rambouillet crossbred ewes remained higher than local ewes even during winter (+17 %) and summer (+19 %). Analysis of variance further revealed that BW of >4 years old ewes of both genotypes were 30 and 38 percent higher than their <1 year old age mated. A significant interaction (p<0.05) was also observed between age and reproductive cycle with effects on BW of both genotypes. Rambouillet crossbred ewes were found more prolific with a fertility rate 85 percent compared with 80% in Khutta local breed. Survival rate among Rambouillet crossbred lambs was 93.4% compared with 84.3 percent in locals. Rams flushed with concentrate before breeding season differed in efficiency of weight gain. Minimum feed required for each kg weight gain was 8.1 kg in group 2 compared with 9.5 and 10.7 in groups 3 and 1 with significant differences (p<.05). Improvement in BCS was higher (45%) in rams of group 3 compared with 31.2 and 18% for groups 2 and 1, respectively. Feed required per unit of improvement in BCS was 1.4 kg in group 3 followed by 1.8 and 4.8 in groups 2 and 1. Analysis of variance revealed that cost of weight (Rupees per Kg) was lowest (153) in group 2 compared with 217.8 and 188.1 in groups 1 and 3, respectively.

The purpose of the present study was to investigate the possibility of using Chufa tubers at different levels in Zaraibi goat rations and its effects on the resultant milk and labenh as well as feed utilization and economical return. Twenty four Zaraibi goats during lactation period were divided randomly into four equal groups (6 doses each). Animals in groups G1, G2, G3 and G4 received 0, 5, 10 and 15 g Chufa tubers/ head/ day, respectively in their diets. Results showed that daily feed intake tended to increase (90.95, 91.63, 92.18 and 93.69 g/kg 0.75 ) with increasing the levels of Chufa tubers (0, 5, 10 and 15g/h). However, the incorporation of Chufa tubers into goats' diet decreased the daily water consumption, as the highest rate of this consumption was recorded with goats fed the control ration (G1), while the lowest consumption was found with those fed on the ration containing the high level of Chufa tubers (G4). Daily milk yield of Zaraibi goats during most of lactation weeks was significantly (p<0.05) higher as a result of supplementing diet with Chufa tubers. The highest milk yield was recorded with G4 (1.059kg) followed by G3 (1.020 kg) then G2 (0.989 kg) and lastly G1 (0.892 kg) and the differences were significant. Moreover, the effect of treatment on milk fat, total solids and ash contents were significant. But, no noticeable effect for tested rations were observed on other milk contents (protein, lactose and solids non fat). Other milk qualities including flavor, acidity and pH values did not show significant differences with the use of all examined diets. Milk produced by goats fed different diets was used for the preparation of the concentrated yoghurt Mediterranean dairy product "labneh". Supplementation with Chufa tubers, at different levels, did not significantly affected the yield, moisture content, titratable acidity, fat content, salt content, total nitrogen, and soluble nitrogen of labneh after processing or during storage. Higher non-protein nitrogen content was observed in labneh of G1 (control) and G2 (5% chufa tubers). Total volatile fatty acids were increased with increasing supplementation rate of Chufa tubers from 5% (G2) to 15% (G4). The highest score in the assessment of organoleptic characteristics of Labneh was for G3 (10% Gufa) , followed by G4 (15% Chufa tubers), then G2 (5% Chufa tubers). The feed utilization efficiency (kg feed intake/kg milk production) based on DM or CP was better with increasing Chufa tubers levels (0, 5, 10 and 15 g/h/day) in goat rations as improvement in G4 reached approximately 12.6 and 14.8%, more than G1 (control), respectively. Accordingly, the economic efficiency (%) was higher due to using Chufa tubers at levels 5, 10 and 15 g/head/ day compared with the control one.
