ABSTRACTThe objective of the present study was to determine changes in biochemical constituents of goat allantoic fluid in different stages of gestation. Allantoic fluid samples were collected from 115 normal pregnant goat uteri at various stages of pregnancy. After expelling of each fetus accompanied by fetal membranes, 10ml allantoic fluid was taken from allantoic sac. Approximate ages of fetuses were calculated by using related formula. At five stages of the five months of pregnancy, the following results were obtained, respectively: creatinine concentrations were: 4.7, 9.3, 9.2, 12.6 and 12.1 mg/dl; uric acid:0.5, 0.2, 0.2, 0.3 and 3.8 mg/dl; urea: 122.7, 153.8, 77.3, 52.1 and 37.6 mg/dl; total protein: 97.8, 129.5, 99.7, 128.9 and 85 mg/dl; glucose: 10.3, 20, 9, 8.1 and 4.2 mg/dl; sodium: 75.3, 77.8, 75.3, 73.5 and 78.9 mmol/L; potassium: 5, 4.6, 5.3, 5.9 and 5.8 mmol/L; chloride: 70, 68.6, 46.9, 30.2 and 30.2 mmol/L.

ABSTRACT The aim of this study was to determine if short-term feeding of high energy diet (pre- and during mating) have any stimulatory effects on body condition score (BCS), live body weight (LBW) and reproductive performance of Zaraibi does. Twenty-four healthy mature does at 31-34 months old and weighed 38-41 kg were randomly allocated in equal numbers (n=12) into control and treatment groups. The control group (low energy=4193 Kcal/kg) was nourished basal diet consisted of concentrate feed mixture (CFM) and berseem hay (BH) at ratio 40:60. In the treatment group (high energy = 4469 Kcal/kg), the protected fat (Mgnaback) ® was added to the basal diet at the rate of 5% of total dry matter intake. Submitting of energy flushing were 21 days before introducing the fertile buck for mating (pre-mating) and continued 42 days during the breeding period (mating season). The total experimental period was 63 days. Thereafter, all does were again fed low energy (control basal diet) by the end
of mating season until parturition. The BCS (based on 1 - 5 scoring classes) and LBW was estimated at start of trial and at the end of each stage including; pre-mating, mating, at the days of 140 gestation and one day after parturition. The kids were weighed one day after birth.The obtained results show no effects for energy levels on BCS and LBW. Contrariwise, during gestation period, BCS and LBW recorded significant increase (P<0.05) with high energy level (3.8 point and 51.8 kg) compared with low energy (3.3 point and 45.2 kg), respectively. However, pregnancy rate, number of kids born, fertility rate, kidding numbers, triplets rate and kid birth weight were higher (P<0.05) with the high energy supplementation than low energy level. It could be concluded that short-term supplementation with dietary energy pre-and during mating can have a beneficial effect on BCS, LBW and reproductive performance of Zaraibi does.

ABSTRACTThis study started by nutritional evaluation (digestion coefficients and feeding value) of reed forage collected from three locations using Rahmani sheep. The best one was used in the second part of the study to compare effect of feeding reed in three forms as fresh, silage or hay on goat’s milk production, compositions and quality ending by economic efficiency. Reed collected from Manzalla is relatively the best but with insignificant difference compared to others. Feeding trials lasted for 20 weeks where four groups were assigned to receive the four experimental rations. All groups were fed on restricted amount of concentrate feed mixture, to cover 50% of the requirements recommended by NRC (1981) while reed, in the three forms, offered ad lib.
Results show that reed silage had the highest digestion estimates, followed by berseem hay then fresh reed and lastly reed hay. Similarly, TDN and DCP were significantly (P<0.05) higher with RS and RF compared to RH and BH (berseem hay as control) rations. TVA's, measured at 4 hrs post feeding in rumen fluid, had no significant differences among the four tested rations. However, microbial protein values were significantly (P<0.05) higher with RS and RF compared to RH and BH rations.Daily milk was significantly (P<0.05) higher for RS and RF compared to RH and BH rations. The highest milk yield was recorded with RS (1.23, Kg) while the lowest for RH (1.01Kg). Milk fat was superior with the three reed forms than berseem hay. Milk quality parameters were not differed significantly among all groups. The feed intake, kg dry matter, was better with reed silage (1.19 kg) and reed forage (1.22 kg) compared with reed hay (1.37 kg) and berseem hay (1.35 kg). Reed silage (RS) recorded the highest economic return followed by RF then RH rations while, the lowest was obtained by BH.It is concluded that reed silage recorded the best feeding values, milk production and quality beside the economic factor.

SUMMARY The aim of this study was to evaluate changes in nutritive values of sugarcane bagasse when treated with fungus and to evaluate performance of growing lambs at partial replacement of CFM with treated sugarcane bagasse. Nine local Ossimi rams were used to evaluate the effects of replacing 15 or 30% of concentrate feed mixture with biologically treated Sugarcane bagasse on nutrients digestibility and nutritive values in terms of total digestible nutrient (TDN) and digestible crude protein (DCP). Ruminal pH, NH3-N and TVFA’s were measured CP and ash contents were increased in biologically treated sugarcane bagasse while, NDF, ADF, cellulose and hemi-cellulose were reduced.
Control group recorded (P<0.05) the highest digestibility coefficients for all nutrients and nutritive values compared with 15% and 30% replacement groups. Control group had higher value of ammonia nitrogen and total volatile fatty acid in rumen liquor at 4 hrs after feeding. Acetic and Propionic acids were higher in control group than treated groups while butyric acid was higher in treated groups than control group. The maximum total fungi counts and microbial protein were observed in control group followed by 15 and 30% replaced ones, respectively. Serum urea, total protein, albumin, globulin, albumin/globulin ratio, GOT and GPT were not significantly changed.Eighteen Rahmany lambs with average body weight 20.00±0.30 kg/head were distributed into three similar groups. Groups were fed, for 120 days, Animals were weighed monthly to determine total and daily gain and feed conversion. The highest total body weight gain, daily gain and lowest feed conversion efficiency were recorded for control group, while medium values were recorded with 15% replacement one. The highest feed cost per head per day and lowest relative economical efficiency were obtained with control group. Controverslly, the lowest feed cost per head per day and highest relative economical efficiency were obtained with 30 % replacement group. The most efficient economical efficiency synchronized with moderate growth rate was obtained with 15 % replacement.
