ABSTRACT<br />This work was carried out on growing Rahmani lambs to investigate the effect of using silage made from some legume and/or grasses on growth performance as well as some rumen and blood parameters. Thirty lambs divided into 5 groups (6 animals each) were fed ad libitum on Cowpea (CW), Millet×Napier grass hybrid (MN), Cowpea - Millet× Napier grass hybrid (CW-MN), Sesbania sesban (SS) and Sesbania-Millet× Napier grass hybrid (SS-MN) in five experimental treatments. Concentrate feed mixture (CFM) was offered with experimental groups to cover 1% of body weight. The feeding trial lasted 112 days. Three lambs of each group were involved in digestion trial to evaluate the feeding values of the tested diets. Results showed that, DM, CP and EE were higher and NFE was lower in SS and CW than MN. The highest OM content was recorded with SS (90.50%) while, CW recorded the lowest value (86.60%). The digestion coefficients of OM, CF and CP of mixture silage (CW-MN) and (SS-MN) were significantly (P<0.05) higher than the other silage groups (CW, MN and SS). The same trend was observed also with DM, EE and NFE digestibility. Thus, the TDN values of both of CW and MN were significantly lower compared with their mixture silage (CW-MN). Similarly, the TDN value of SS-MN mixture silage was significantly (P<0.05) higher than those in SS and MN single silages. The highest value of DCP was recorded with SS (14.95) followed by CW (14.19), SS-MN (12.74) and CW-MN (11.84) and the lowest with MN (7.01) where all differences were significant. The daily feed intake tended to increase with SS-MN group (69.0g/ kgW0.75) and CW-MN group (68.56g/kgW0.75) compared with the other silage groups. The highest value of water consumption was recorded with SS group whereas, CW-MN group recorded the lowest value. The effect of legume or grass silage and
their mixtures on some rumen parameters were significant. Whereas, the effect of silage treatments on most blood parameters were not significant.<br />As for growth rate, the highest value was recorded with group SS-MN (137g) followed by CW-MN (133g), SS (124g) and CW (120g) and finally MN that recorded the lowest value (115g). The differences among groups were significant. The same positive effect of mixtures silage was observed also with feed utilization efficiency based on DM and TDN. Accordingly, it could be recommended to using mixtures silage such as SS-MN and CW-MN in growing sheep rations owing to their positive effect on growth performance.

ABSTRACT<br />Towards identifying potential production of Barki sheep, this study was implemented to evaluate performance of Barki ewes at late gestation and lactation period by feeding them on standard allowances (Tomi 1963) vs. a higher level 120% of that allowances. Twenty Barki ewes 2-3 years old and 46.5 kg live body weight at the last six weeks of gestation were divided into two equal groups (10 ewes each) that received 100% and 120% of Tommi allowances (1963). The first group (T1) and second are (T2) were fed 1 and 1.2Kg /head/day concentrate feed mixture, respectively beside 2 kg berseem and 200g rice straw / head.
The weight of lambs at birth and weaning were not influenced by the level of feeding. The average daily gain of lambs in T2 was improved by 8.0% compared with T1, but the differences between the two treatments were not significant.<br />Daily actual milk yield in T2 was significantly (P≤0.05) increased and 4%- fat corrected milk yield was improved by 33.70% compared with T1. Milk composition indicated that ewes in T2 had higher (P≤0.05) ash, lactose, total solids (TS) and solids not fat (SNF) %, while fat and crude protein (CP) % were not affected compared to ewes in T1. Regarding the daily milk nutrient yields, it could be observed that fat, protein and total solid yields were significant higher in T2 comparing with T1. Based on new born growth performance measurements, it could be emphasized on 100% of Tommi allowances (1963) as satisfying level to cover the nutritional requirements of barki sheep.

ABSTRACT<br />This study was conducted to evaluate the effect of microbial inoculates of whole corn plants on silage quality, growth performance, blood constituents, carcass characteristics and economic efficiency of Rahmani lambs. Corn plants at doughy stage of maturity were inoculated with microbial inoculant (MID/1®) then chopped and ensiled. The results pointed that pH value of silage was 3.95 for un-inoculated and 3.80 for inoculated silage. Lactic acid concentration was 4.71 and 5.25% for un-inoculated and inoculated silage, respectively. Inoculated silage had higher concentration of total volatile fatty acids (3.00 %), acetic (1.15 %), propionic (0.85 %), butyric (0.35 %) and valeric acid (0.12 %) than un-inoculated (2.75, 0.99, 0.66, 0.25 and 0.09 %, respectively). Inoculated corn silage had a lower ammonia concentration (0.045 % on DM basis and 2.59 % ammonia of total nitrogen), than un-inoculated (0.053 and 3.87 %, respectively). It was noticed that corn silage with microbial inoculate increased crude protein, ether extract and ash, while decreased crude fiber, neutral detergent fiber and acid detergent fiber. Inoculate corn silage increased most minerals contents and gross energy value. Daily gain was significantly (P<0.01) increased (196.47 vs. 161.33 g/h/d). Feed intake of corn silage and feed conversion (6.56 vs. 7.80 kg feed/kg gain) were also increased (P<0.01).The results indicated that feed cost for producing one Kg gain was less for lambs fed inoculated corn silage compared with those fed un-inoculated, whereas economic efficiency improved by 19%. Inoculation significantly (P<0.05) increased hemoglobin, red blood cells count and phosphorus concentration. Dressing percentage2, hind quarters, edible offals, the 9th, 10th and 11th ribs weight were significantly (P<0.05) higher. Yet, feeding inoculated corn silage could improve growth performance, feed conversion, carcass characteristics and decreased feed cost of producing one Kg gain (19% less than un-inoculated silage).

ABSTRACT<br />Twenty four pregnant ewes (1/2 Ossimi X 1/2 Chios) averaged 49.75 ± 2.65 kg were used to evaluate the combined effect of vitamin E and selenium (Se) injection on growth performance and some physiological reactions of these ewes and their lambs. The ewes were randomly divided into two equal groups (12 ewes each). The first group (G1) served as control and injected with 1.0 ml/head of saline solution (0.9 % NaCl), while the second group (G2) were injected intramuscularly with 1.0 ml/head viteselene. Each ml of viteselene contained 150 mg vitamin E acetate and 1.67 mg saodium selenite. The ewes were injected with viteselen biweekly starting at 4 weeks late gestation and during suckling period for 12 weeks.
The results showed that lambs born from treated ewes (G2) recorded higher (P<0.05) body weight and daily gain than those born from control ewes (G1). Blood Hb concentrations significantly (P<0.05) increased for G2 compared with G1. Lambs born from treated ewes had significantly (P<0.05 to P<0.01) higher values of red blood cells, hemoglobin, packed cell volume and mean corpuscular hemoglobin concentration than those born from control ewes. The total count of leucocytes increased (P<0.05) for treated ewes, lymphocytes and eosinophils percentages increased (P<0.05) while neutrophils, basophils and monocytes were insignificantly changes compared with the control ewes. Lambs born from G2 showed insignificant increase in total count of leucocytes accompanied with an increase (P<0.05) in lymphocytes and a decrease (P<0.01) in neutrophils with no significant changes in eosinophils, basophils and monocytes percentages compared to lambs born from G1. In vitamin E plus Se-injected ewes and their lambs, there were significant (P<0.05 to P<0.01) increases in plasma total protein and globulin. Changes in plasma albumin, total lipids and glucose concentrations for treated ewes and their lambs were not significant, while plasma T3 and T4 levels were higher (P<0.05) in treated ewes compared with control ewes.Plasma level of T3 only was higher (P<0.05) in lambs born from treated ewes (G2) than those born from control ewes (G1). These results indicated that administration of vitamin E plus Se to ewes at 4 weeks late gestation and during suckling period improved growth performance, some immune responses and viability of their lambs as a result of favorable signs in their physiological reactions.

SUMMARY<br />Thirty Rahmani ewes were used to study the effect of ovsynch protocol (GnRH+PGF2) on the reproductive performance of Rahmani ewes. They were equally divided into three treatment groups. All ewes in the treated groups were intramuscularly injected on Day (0) with 1 ml GnRH analogue, (Receptal®) followed by intramuscular injection of 0.7 ml PGF2α analogue (Estrumate) either by 5 days (G1), 6 days (G2) or 7 days (G3) . A second dose of GnRH analogue (1 ml) was given on day-7 (G1), day-8 (G2) or day-9 (G3), and artificial insemination was carried out 24 h later.<br />Results showed that 1 out of 10 ewes exhibited estrous activity in G1 vs. 3 out of 10 ewes in both G2 and G3. Ewes in G1 had the highest (P<0.05) lambing rate (60%), compared to G2 (50%) and G3 (40%). Litter size and fecundity were higher (P<0.05) in G1 (1.67 lambs/ewe and 100%), followed by G2 (1.40/lambs/ewe and 70%) and G3 (1.25/lambs/ewe and 50%). P4 concentration was high (P<0.05) in all treated groups as affected by the 1st GnRH injection. Thereafter, P4 decreased in all treated groups after PGF2 injection. Post-2nd GnRH injections, P4 levels showed a pronounced increase in all treated groups. At days 21to 24 post-mating, P4 levels showed the highest values in all treated groups.Based on the obtained results, using GnRH-PGF2α-GnRH (GnRH, 0 d; PGF2α 5 d laterandGnRH 48 h later) protocol during the breeding season (January) can be used for synchronization of ovulation to reduce service and lambing intervals of Rahmani ewes.
