Sixteen Abou-Delik male lambs, of an average live body weight 22.3 ± 3.02 kg and aged three months were used in this study to assess the effect of intensive and semi-intensive management systems on growth performance, carcass traits and economical efficiency. Lambs were randomly divided into two symmetric groups (eight lambs each) and allocated to different management systems. Lambs of group one (G1), were represent intensive management system, while, lambs of group two (G2), considered as the semi intensive management system, The experiment was lasted for 180 days. At the end of experimental period, fourteen lambs were slaughtered and different carcass data were collected. Analysis of variance indicated that no significant difference (P< 0.05) were found between the intensive and semi intensive management systems in relation to final live body weight (37.63 kg vs. 36.88 kg), total live body weight gain (15.31 kg vs. 14.54 kg) and average daily gain from weaning age up to 9 months of lambs age (84.1 gm vs. 79.9 gm), respectively and live body morphemetric measurements of Abou-Delik lambs. There was a marked highly significant effect (P < 0.01) of management system and period on feed conversion ratio. Highly significant differences (P <0.001) between the two management systems. Feeding cost per head per day were LE 7.14 and LE 4.49 for the intensive and semi-intensive system, respectively. Benefit/Cost ratio were LE1.25 and LE2.26 for lambs at 6 months of age and 0.42 and 0.46 for the corresponding indicators at 9 months of age. Gross margin estimates were LE 156.5, 451, -390.7 and -243 for G1, G2 at 6 and 9 months of age, respectively.

Ovulation in chicken is the process of emergence the egg yolk by controlling the steroid hormones, which is followed by oviposition that influence by several factors. Egg yolk is a huge oocyte contains fat in water emulsion with about 50% dry weight, its rounded and centrally located. The experiment was carried out to investigate the effect of oviposition time on egg external traits (egg weight, egg length, egg breadth), yolk characteristics (yolk weight, yolk high, yolk diameter, yolk index, and the proportion of yolk weight to egg whole weight), and investigate the correlations between these characteristics by using Ross 308 hybrid.When the flock was 30 weeks age, 150 fertilizes egg was used, which collected in three times, Period (1) = 9:30 am, Period (2) = 11:30 am, and Period (3) = 1:30 pm, which supplied from KOSAR company.The results reveal significant differences between the times of collection for all the yolk characteristics and egg external traits.It does conclude the yolk characteristics were differs significantly between the oviposition times and the yolk weight was highly correlated with yolk diameter, egg breadth, and proportion of yolk weight to the whole egg weight.

The main objective of this study is to describe and characterize farming systems and type of farms for ruminants under the environmental conditions in North of Delta (Kafr El-Sheikh, G1) and Middle Egypt (Bani - Swef, G2) governorates. Data were collected through visiting seven districts within each governorate. Randomly chosen 10 villages in each district. The visits were monthly and the study period was from December, 2013 to June, 2015. Data collected included type of farms, number of farm animals in each farm, feeding systems followed in winter and summer. Also, air temperature (AT C°) and relative humidity (RH %) were recording to calculate temperature humidity index (THI). Type of farms surveyed under study were classified to, smallholder (SHF), special farm (SF) and governmental farm (GF). Production system of farms were classified to three categories, milk production, and meat production and mixed of milk and meat production. The system of farms were described depending on farm animal as cows only, buffaloes only, mixed of cows and buffaloes, mixed from large ruminants as cows with small ruminants (sheep and goats) or buffaloes with small ruminants (sheep and goats). The number of farms own agricultural tenure were recorded and the percentages of these farms were 57% and 49% in G1 and G2, respectively with least squares means of 12.61±5.5 and 8.91± 6.52 Fadden., Results revealed that climatic conditions was better in middle Egypt than in north of Delta because of the low THI. Also, number of animals and number of smallholders were larger in G2 compared with G1. Small holder's percentages were 66.67% and 74.42% of the total surveyed farms in G1 and G2, respectively. Special farms percentages were 28.57% and 20.93% of the total farms in G1 and G2 in G1 and G2, respectively. The governmental farms had the lowest percentages, 4.76% and 4.65%, respectively. The number of dairy farms in G1 was higher than in G2. The fattening farms and farms of both milk and meat production were higher in G2 compared with G1. Farms of G2 depended on family labor with percentage of 57.14%, on family with help of hired labor with 19.05% and on hired labor only with 23.81%. The percentages in G1 were 45%, 12.5% and 42.5%, respectively. The most used feeding system was system (4) which includes combination of green, roughages and concentrates with percentages of 64.1% and 67.7% in winter for G1 and G2, respectively and with 66.7% and 64.7% in summer season, respectively. While the lowest system in winter was system (2), (roughages and concentrates) with 7.7% and 2.9% in G1 and G2, respectively, the lowest system used in summer was system (1) for G1 (5.1%, for green and concentrates) and system (2) for G2 (8.8%, for rough and concentrates), respectively. It is conclude that the climatic conditions in G2 best than G1 due to lower of THI in G2 that reflects of numbers the fattening farms and mixed frames (milking and fattening) were more in G2 compared with G1., Feeding and workers under G2 conditions lower of costs of compared with G1 due to depended on green forage in feeding and the workers from family .The recommendation increased farms of animal production under conditions in Middle Egypt (G2).

Genetic and crossbreeding parameters for birth weight (BWT) were estimated in pure Baladi (BB), Abondance (AB) with BB crossbred and Tarentaise (TR) with BB crossbred calves. Data were collected from breeders in two governorates and from Sids Experimental Farm belonging to Animal Production Research Institute. Data included 9334 records of calves born for 174 sires and 5182 dams. Data consisted of seven genotypes; BB, ½ AB/TR ½ BB, ¾ AB/TR ¼ BB and ⅞ AB/TR ⅛ BB. Group differences were highly significant, (P<0.0001). Least squares means of BWT were 22.3, 32.4, 32.4 and 32.6 kg for BB, ½ AB, ¾ AB and ⅞ AB, respectively and were 32.0, 32.0 and 31.9 kg for ½ TR, ¾TR and ⅞ TR, respectively. Individual and maternal additive and maternal heterosis effects were studied, variance components and heritability estimates were estimated. The individual additive effects of AB and TR for BWT were significant being -9.98 kg and -9.43 kg, respectively. Maternal additive effects were significant and positive being 4.86 kg and 4.81 kg for AB and TR, respectively. Maternal heterosis estimates were non-significant with small magnitude and was negative for AB crossbreds (-0.06 kg) and was positive for TR crossbreds (0.12 kg). Heritability estimates for BWT were 0.16, 0.51 and 0.55 for BB, AB crossbreds and TR crossbreds, respectively. In general, Crossbred calves of AB or TR were higher in BWT than pure BB calves. Individual additive effects show an advantage for AB and TR crossbreds, while maternal additive effects expressed the superiority of the BB dams over the crossbred dams. Results reveal that genetic improvement of BWT in BB could be achieved by crossing with AB or TR breeds for higher BWT.

An experiment was designed on 165 local Sinai laying hens (150 females + 15 males), 47 wk-old, were equally divided into five dietary treatments to determine possible benefits from dietary supplementation with proanthocyanidins to the layer's diet of grape pomace and green tea extracts (GPGT extract) at levels (0, 50, 100, 150 and 200 mg/kg diet) on productive and reproductive performance during the laying period from 47 to 62 wk of age. Results illustrated that egg number/hen or laying rate (%) significantly (P≤0.05) improved due to feeding the diet supplemented with 150 mg GPGT extract/ kg diet as compared to the control group. Also, the hens fed diet supplemented with 150 mg GPGT extract recorded the highest value of egg mass when comparing with the control and other dietary treatments. Fertility % of eggs from hens fed diet supplemented with 100 and 200 mg GPGT extract / kg diet was significantly (P≤0.05) increased compared to the low level of extraction (50 mg/ kg diet) and control diet. The diet supplemented with 100 mg GPGT extract / kg diet had higher hatchability % and chick weight than the control diet. In addition, total antioxidant capacity yolk content in was significantly increased as a result of feeding on diet with 150 mg GPGT extract/ kg diet compared to the control diet. It could be concluded that supplementation 150 mg GPGT extract / kg diet in Sinai hen's diets can be used to maximize the egg production performance, quality of egg yolk and economic efficiency from 47 to 62 wk of age. Moreover, these results suggest that 100 mg GPGT extract/ kg layer diet can be applied for optimal performance of reproductive traits.
