In a feeding trial with rabbits for eight weeks, soya bean (control diet) was substituted by sieving wastes of the Egyptian clover seeds (GSPB, treated diet) to study its possibility, effects and economics for rabbits. This substitution had been succeed; since the treated diet had improved (than the control diet) either of final live body weight of rabbits, daily and total live body weight gain, feed intake and conversion, economic efficiency, boneless meat, and chemical composition of the rabbits' meat without any adverse effect on rabbits' health. So, this substitution is recommended when GSPB is available.

This study was carried out at a private farm, Dakahlia governorate during the period from November 2013 to April 2014 to evaluate the effects of oxytocin (OXY) and prostaglandin (PG) on uterine involution and consequently on postpartum productive and reproductive performance of primiparous Friesian cows. Total of 15 primiparous cows with live body weight (380-420 kg were divided into 3 groups, 5 in each. Animals were i.m. injected with saline solution (control, G1), 50 IU OXY (G2) and 3 ml PG (Estromate, G3) within 12 h post-calving. Routine examination of the genitalia per rectum was conducted once weekly to judge the uterine involution by ultrasonography to determine diameter of uterine horns (gravid and non-gravid), cervical diameter and vaginal length on day 10, 15, 22, 27 and 32 of postpartum period. Animals were hand milked twice/day and those in heat were naturally inseminated and pregnancy was diagnosed by rectal palpation on day 45 post-insemination. Postpartum 1st estrus (PPFEI) and service (PPFSI) intervals, estrus (ER) and conception (CR) rates, days open (DO), number of services/conception (NSC), and service period length (SPL) were recorded. Results showed that diameter of non-gravid horns showed insignificant group differences. Diameter of gravid horns was wider (P<0.05) in G1 than in G2 and G3 from 10- up to 32-day postpartum, indicating earlier uterine horn symmetry in treatment than in control groups. Postpartum interval required for symmetry in gravid and non-gravid horns was shorter in G3 and G2 (21.4 and 20.9 d) than in G1 (28.7 d), respectively. Cervical closure was completed earlier in G2 (22.8 d, P<0.05) and in G3 (25.5 d, P≥0.05) than in G1 (28.6 d). Resumption of vaginal length had similar interval in all experimental groups, ranging between 18 and 19 d. Cows in G2 showed higher (P<0.05) ER (100 vs. 80%) and CR (80 vs. 60%), lower NSC (1.75 vs. 2.30 serv.), and shorter SPL (15.75 vs. 28.33 d) than in G1. Cows in G3 increased ER (80 vs. 100%) and decreased DO (52.33 vs. 98.0 d) as compared to G1, but insignificantly improved other reproductive parameters. Milk yield as total or daily milk yield was not affected significantly by treatment.
Based on the foregoing results, oxytocin injection (i.m.) within 12 h post-calving produced early uterine involution and markedly affect in positive trends on the reproductive performance of Friesian cows without pronounced effect on milk yield.

The objective of this study was to investigate the beneficial effects of early age thermal conditioning and lighting regime to reduc adverse effects of hot weather condition, especially on the oxidative stress and immune function of Muscovy ducks. Experimental design was a 2 × 2 (4 groups of 160 ducks) during summer season. Ducks were divided into two equal groups. The control group, maintained under normal ambient temperature, the second group were exposed to early age thermal conditioning (exposed to temperature of 39±1°C for 6 h at 5th day of age and then subjected to normal ambient temperature. Each group of the previous groups were divided into subgroups at beginning 4 week of age. The first subgroup was subjected to normal day light (16 h light, 8h dark) and the second subgroup was subjected to intermittent light regime of 4h light 2h dark (make 16h light, 8h dark). Blood samples were collected at 12 weeks of age for assay of some blood parameters.
The obtained results could be summarized as follows:
Body temperature was significantly decreased by both early-age thermal conditioning or intermittent light regime. Plasma lysozyme concentration of Muscovy ducks were insignificantly increased in early heat exposed group compared to the control group. However, it significantly increased in intermittent light regime group. Corticosterone level and Hetrophil/lymphocyte ratio decreased in both thermally-conditioned and intermittent light groups compared to control group. Plasma malondialdehyde was significantly decreased in early heat exposed group compared to the control group. However, it insignificantly decreased in intermittent light regime group compared to control group. Superoxide dismutase and catalase enzymes increased in both thermally-conditioned and intermittent light groups compared to control group. It is concluded that a combination of early age thermal conditioning and intermittent light regime reduces oxidative stress and improves immune responses and this combination can be considered as bio-stimulation methods for the birds to reduc the negative effects of high ambient temperature.

This experiment was conducted to study the effect of chemical and biological treatments of pruning peach trees by-products (PTBP) on chemical composition, degradability, cell wall constituents, digestibility and nutritive value and its feeding effect on productive performance of growing sheep. Thirty Ossimi lambs with average body weight 18.00±0.20 kg and 4 months old were used in this study for 120 days. Lambs were distributed into five similar groups (6 lambs each) and randomly assigned to five experimental rations. The five respective rations composed of concentrate feed mixture (CFM) + roughage (PTBP), the control ration (R1) contained untreated PTBP; (R2) treatedPTBPwithTrichoderma reesei; (R3)treated PTBP with Trichoderma viride;(R4) treated PTBP with Trichoderma reesei + Trichoderma viride and (R5) 3% urea treated PTBP. The DM, OM and CP disappearance and effective degradability (ED) va lues were in situ determined. The digestibility and nutritive values of experimental rations were determined using fifteen adult Ossimi rams. Rumen liquor and blood samples were collected at the end of collection period. The results showed that fractions of DM (a&b) and (ED) were significantly (P<0.05) increased with treated PTBP either with urea or fungi compared to control (untreated PTBP). The highest degradable values of DM, OM and CP were observed with R4. Nutrient digestibility and feeding values (TDN and DCP) were higher (P<0.05) for rations containing treated PTBP than control. The highest values of TDN and DCP were observed for R4. Digestibility of cell wall constituents (NDF, ADF, cellulose and hemicellulose) were improved by treatments. Concentrations of rumen parameters (NH3-N and TVFA’s) were significantly increased by treatments. However, no significant differences were found in blood constituents (total protein, albumin, globulin, GOT, GPT and urea) among the different experimental groups. Blood constituents were generally normal in all experimental groups. Growth performance with respect to total body weight gain and average daily gain (ADG) were improved by biological treatments. The same trend was observed for feed conversion and economic efficiency and the best values were recoded with R4. It was concluded that inclusion of treated PTBP to rations of growing Ossimi lambs could improve their performance especially treatment of PTBP with fungi.
