ABSTRACT<br />This experiment was conducted on Twenty-two dairy Zaraibi nanny goats to assess the effect of feeding either un-inoculated corn silage (UCS), or microbial inoculated corn silage (BICS) on quantity of feed consumption, live body weight, milk production, milk composition and some blood parameters. Zaraibi nanny goats were allocated in two treatment groups (n=11). The does were received diets from pre-mating up to end of lactation period. Nannies were similar in breeding season and production performance. The concentrate feed mixture (CFM) and wheat straw (WS) were fed as basal diet to the two experimental groups. The first group (G1) was fed basal diets + un-inoculated corn silage while, the second group (G2) nourished basal diets + microbial inoculated corn silage. The amounts of diets were adjusted according to NRC (2007) allowances. Both G1 and G2 were housed in separated pens under similar environmental condition. The salt blocks and fresh water were freely given throughout the
experimental period. The results indicated that the average feed consumption of silage and total dry matter were increased for does fed BICS (G2) compared to those fed UCS (G1), while consumption of CFM and WS were not affected. There are no significant differences in live body weight changes between the experimental groups during different periods (from mating to post weaning). Yield of suckling and lactation milk was significantly (P<0.05) higher for G2 than G1.<br />Milk contents of protein and lactose during suckling and lactation periods were significantly (P<0.05) higher in G2. G2 also during suckling and lactation periods had significantly (P<0.05) higher hemoglobin, serum glucose, total protein, albumin and urea nitrogen than G1,. Serum globulin recoded booster level in G2 than G1 during suckling period (P<0.05). It is concluded that feeding microbial inoculated corn silage increased milk production, milk contents of protein and lactose and increased hemoglobin, serum glucose, total protein, albumin and globulin.

ABSTRACT<br />This work was carried out on Zaraibi kids to investigate the effect of different suckling systems on kids' performance and health status during the suckling period. Forty Zaraibi does (three successive lactations) were selected from El-Serw Station herd and divided into four groups, considering age, milk yield and litter size. Born kids were kept with their dams till being 13 weeks old (free natural suckling, G1). Kids in G2, were separated from their dams one week after birth to be raised artificially on goat's milk. G3 artificially suckled mixed milk (50% goat milk: 50% cow milk) while G4 suckled 100% cow milk. The obtained data indicate that daily consumption of milk was significantly affected during the first weeks (2nd and 4th weeks) where the highest value was recorded with G1 (405 and 553 ml) while the lowest value was recorded with G4 (345 and 483 ml), respectively. Milk consumption by Zaraibi kids was approximately similar for the 4 groups within the period from 6th to the 8th weeks of lactation, but it was noticeably reduced with the artificial suckling group during the last weeks. In addition, some kids (ranged from 3 to 5 ) of those artificially suckled groups stopped suckling during the last two weeks, without any adverse effect on their weaning weight. Weaning weight of quadruplets kids were heavier with artificial suckling (being 10.0, 9.80 and 9.63 kg in G2, G3 and G4, respectively) than natural suckling (9.35 kg). Similarly, the weaning weight of triplet kids was better for the three groups suckled artificially expressed as G2, G3 and G4 (being 10.14, 9.90 and 9.70kg, respectively) compared with G1 (natural suckling, 9.52 kg). The mortality rates were
8.70, 9.09, 13.04 and 17.39 % for G1, G2, G3 and G4, respectively. The cases of mortality recorded the highest estimate among triplet kids and quadruplets kids especially during the first weeks of suckling especially in G4. Generally, both groups of natural suckling (G1) and artificial suckling on goats milk (G2) had reduction in incidence of bloat (indigestion) and diarrhea (digestive disturbances), thus showed less mortality rate among kids.<br />Accordingly, artificial rearing seems a good alternative for young kids especially for those born twins and more or when early weaning is demand. However, in case of economics push to save goat milk and replace it with cow milk, more studies are needed since results showed high mortality in kids when using it for suckling.

SUMMARY<br />Eight different morphometric dimensions were monitored on 106 lamb carcasses belonging to three Catalan meat sheep breeds (Ripollesa, Rousillon Red and Xisqueta). Our purpose was to examine differences with regard to measurable carcass dimensions and also to establish between and within breed relationships among the carcass components. Measured variables included: carcass weight (CW), leg length (LL), carcass internal length (IL), carcass length (CL), chest width (ChW), hip width (HW), chest depth (CD), leg circumference (LC) and chest circumference (CC). From these measurements seven indices were obtained. Roussillon Red carcasses were the shortest, with the largest leg capacity, the lowest corporal index and giving a sense of “squareness”. Xisqueta carcasses presented the longest leg length. Ripollesa carcasses were the smallest in chest circumference. The rest of the variables were similar between breeds.

ABSTRACT<br />The effect of dietary yeast culture (YC) supplementation during pre-mating and gestation periods on reproductive performance and some blood constituents were studied on 39 Damascus does aged 3-4 years and weighed 45.87±1.00 kg. The animals were divided into 3 comparable groups (13 does each). The 1st group fed a basal ration composed of 60% concentrate feed mixture (CFM) plus 40 % clover and rice straw. The 2nd and 3rd groups fed respectively the same basal ration plus daily supplement of 2.5 or 5.0 g YC which added to a part of the ground CFM. Results showed that YC supplementation significantly (P<0.05) improved reproductive ability, conception rate, fertility, fecundity, prolificacy, kids born/does joined, kids weaned/does kidded, kg of kids born or weaned/does joined or /does kidded. It also resulted in higher (P<0.05) serum total protein, albumin, total lipids, creatinine, zinc concentrations and AST activity but it decreased cholesterol and urea concentration than control does. Serum total protein, albumin concentrations and A/G ratio were increased (P<0.05) and globulin concentration was decreased (P<0.05) during the last weeks before kidding. AST activity significantly decreased (P<0.05) from mating up to wk 8, thereafter increase was mild and gradual till kidding.. Meanwhile ALT concentration recorded its minimum value at the 10th wk of pregnancy while it increased gradually till kidding. Serum total lipids concentration was significantly decreased (P<0.05) from mating till kidding Total cholesterol concentration was significantly increased (P<0.05) from mating up to the 8th wk of pregnancy, thereafter it was gradually decreased till kidding. Concentration of blood urea recorded its minimum value at the 10th week of pregnancy (mid pregnancy). Thereafter it gradually increased till 18th week and decreased till kidding. Meanwhile, serum creatinine concentration increased gradually from conception till kidding. The concentration of serum Zn recorded its maximum value at the 8th week of pregnancy, thereafter it gradually decreased till kidding. However, the concentration of serum Fe recorded its minimum value at the 14th week of pregnancy, thereafter it gradually increased up to the 18th week and decreased till kidding.It can be concluded that yeast culture supplementation could be added to does ration at the level of 2.5 or 5.0 g/head/day during pre-mating and gestation periods in order to improve reproductive traits and blood components.

ABSTRACT<br />The two studies reported performance of Rambuoillet crossbreds (ewes and rams) with local sheep breed Khutta under grazing system of transhumant.<br />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.

ABSTRACT<br />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/kg0.75 ) 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.
