Forty Zaraibi goats with average body weight of 34.64±0.79 kg and 3-4 years old were divided into four similar groups (10 in each). The goats were fed from the last two months of pregnancy till the fifth month of lactation the basal ration containing 0.8 kg concentrate feed mixture, 0.2 kg barley grain and 5.0 kg berseem without additive (control) or with 2 g/head/day rumen protected methionine (RPM) or 2 g/head/day rumen protected choline (RPC) or 2 g/head/day RPM + 2 g/head/day RPC (RPM+RPC). Results show that average daily dry matter intake (DMI) by goats was nearly similar for the different groups. The RPM+RPC group showed significantly (P<0.05) the highest digestibility coefficients and nutritive values followed by RPM and RPC groups, while the control group had the lowest values. Milk yield increased by 19.36, 12.62 and 31.31% for RPM, RPC and RPM+RPC groups, respectively. The RPM+RPC group showed significantly (P<0.05) higher milk composition. Milk yield was increased with the progress of lactation from 1st to 2nd month and decreased thereafter, while milk composition showed the opposite trend. Rumen protected methionine and/or choline additives increased significantly (P<0.05) body weight of goats during the different periods compared to control group. The concentrations of total protein, albumin and globulin in blood serum were significantly (P<0.05) the higher in RPM+RPC group. The total DM intake and total feed cost were nearly the same for the different groups. The RPM+RPC group showed significantly (P<0.05) higher total TDN and DCP intakes and lower amounts of DM, TDN and DCP required per kg milk. The RPM+RPC group recorded significantly (P<0.05) higher total and net revenue and net revenue improvement. The net revenue for RPM, RPC and RPM+RPC increased by 32.27, 21.75 and 53.19% compared to control group, respectively.

Forty Zaraibi goats with average body weight of 34.64±0.79 kg and 3-4 years old were divided into four similar groups (10 in each). The goats were fed from the last two months of pregnancy till the fifth month of lactation a basal diet containing 0.8 kg concentrate feed mixture, 0.2 kg barley grain and 5.0 kg berseem without additive (control, G1) or with 2 g/head/day rumen protected methionine (RPM, G2) or with 2 g/head/day rumen protected choline (RPC, G3) or 2 g/head/day RPM+ 2 g/head/day RPC (RPM+RPC, G4). After kidding, theproducedkids were left with their dams in pens and allowed to sucke dam colostrum and small amounts of mash concentrate feed mixture, barley grains and berseem during the suckling period for three days.Results revealed thatyieldand components of colostrum were the highest (P<0.05) in G4. Colostrum yieldincreased and its components decreased gradually from 1st to 3rd day after kidding in all groups. Percentages of non-casein and non-protein nitrogen in colostrum decreased (P<0.05), however percentages of albumin, globulin, β-lactoglobulin, calcium, phosphorus and total amino acids increased (P<0.05) with RPM and/or RPC supplementation as compared to control group. Body weight, total and daily weight gain of produced kids were highest (P<0.05) in G4. Concentrations of total protein, albumin and globulin in blood serum were higher (P<0.05) in G4. Kids in G4 showed the lowest percentage of diseases incidence and mortality rate.
It could be concluded that supplementing diets of Zaraibi goat does, during the last month of pregnancy up to the suckling period, with 2 g/head/day rumen protected methionine and 2 g/head/day rumen protected choline improved yield and chemical composition of colostrum, which consequently improved growth rate, blood serum proteins, and reduced diseases incidence of their kids suckled colostrums.

The present study was designed to investigate the effect of using cucumber vines straw (CVS) instead of clover hay in growing NZW rabbit diets without or with prebiotic (mannan oligosaccharide ,MOS) or multi-enzyme (Natuzyme, NZ) supplementation on nutrient digestibility, nutritive values, caecal microbial activity and itsvolatile fatty acids (VFAs) content, carcass traits and some blood constituents. A total number of 63 six-week old NZW rabbits were randomly divided into 7 groups; each group included 3 replicates of 3 rabbits each and reared in metallic batteries under similar conditions. Graded levels of cucumber vines straw were used to replace 0, 25, 50, 75 and 100% clover hay, 100% clover hay level without or with NZ or MOS at 1g/kg diet each, respectively, and to form 7 pelleted diets similar in all nutrients content and fed to rabbits from 6 to 12 weeks old. Results show that neither dietary CVS till 30% level (100% instead of clover hay) nor supplementation with NZ or MOS had significant effects on caecal VFA content (Acetate, propionate, Butyrate, Isobutyrate, Valerate, Isovalerate), carcass characteristics (skin+foot, liver, heart, kidneys and abdominal fat weights as percentages of live body weight) and plasma constituents ( total lipids, total cholesterol, creatinine and enzymatic activities of alanine aminotransferase (ALT) and aspertate aminotransferase (AST)). Moreover, all other studied performance traits were not influenced with CVS-diets till 22.5% or 30% level supplemented with NZ or MOS. However feeding 30% CVS-diet without NZ or MOS significantly decreased nutrients digestibility coefficients, nutritive values (digestible crude protein, total digestible nutrients, and digestible energy, caecal pH value, relative carcass yield weights for carcass empty, total edible parts and plasma constituents ( total proteins, albumin and globulin) and increased caecal ammonia (NH3-N) concentration compared with those of control. Supplementing NZ or MOS into 30% CVS diet significantly negated (similar to control) all these adverse effects occurred by this level of CVS on studied traits. It could be concluded that CVS can be successfully used till 22.5% level (75% of clover hay) for feeding growing NZW rabbits without any healthy troubles or adverse effects, such level may be raised till 30% (100% instead of clover hay) in NZW rabbit diets supplemented with either NZ or MOS.

Data used in this investigation were collected from 4370 records relevant to 874 purebred Friesian cows which belong to Shobratana Animal Production Society, located in the north part of Delta region near Tanta city in Egypt. These cows were daughters of 43 sires. The records used covered the period from 1985 to 2003. The following six productive and reproductive traits of the first lactation were analyzed: Total Milk Yield (TMY, kg), dry period (DP, day), lactation length (LL, day), days open (DO, day), calving interval, (CI, month) and age at first calving (AFC, month).sire random effect and month and year fixed effect. Data were analyzed using Linear Mixed Model Least Squares and Maximum Likelihood (LSMLMW) computer program of Harvey (1990). The overall means of TMY, DP and LL were 5387 kg, 72.9 days and 327 days, respectively. The overall means of CI, DO and AFC were 13.4 month, 121 days and 27.8 month, respectively. Heritability estimates for TMY, DP, LL, CI, DO and AFC were 0.141±0.074, 0.109±0.069, 0.040±0.057, 0.104±0.068, 0.202±0.084 and 0.217±0.087 respectively. The ranges of breeding values of all sires in the pedigree for TMY, DP, LL, DO and CI were 685 kg, 18 day, 8.15 day, 48.2 day and 1.05 month, respectively. Spearman rank correlations and Pearson correlations among estimated breeding values of all sires in pedigree provided by the genetic analysis ranged between -0.712 to 0.907. The objectives of the present study were: 1) to estimate some genetic and non-genetic factors affecting productive and reproductive traits, 2) to estimate genetic and phenotypic parameters for these traits and 3) to estimate breeding values for sire Friesian cows in this farm. Rank correlations of animals between traits were the lowest for reproduction traits. It could be concluded that improving the environmental conditions will improve these traits.

Milk marketing was studied in a hundred and fifty farms practicing mixed (Crop / livestock) farming system. The studied farms were selected randomly from three governorates: two in Delta (El-Beheira (B) and Kafer El-Sheikh (K)) representing (buffalo–rice based system) and one in Qena (Q) for (buffalo -sugar cane based system) in Upper Egypt. The study aimed to study milk production and marketing efficiency in these governorates. A questionnaire was designed and administered in the study areas to collect data from dairy farms. Data included milk yield, some reproductive parameters, milk prices, milk market and milk for home consumption. Results for cow milk yield recorded that 60.19%, 46.95% and 72.44% sold and home consumption was 39.81%, 53.05% and 27.56%. While, buffalo milk was 65.63%, 42.58% and 83.63% sold and for home consumption was 34.37%, 57.42% and 16.37% for K, Q and B respectively. Two types of traders share farmers milk revenues wholesalers; 23.44%, 12.05% and 12.18% while, retailer share were 15.63%, 17.45% and 10.71 for cow milk for K, Q and B, respectively. Buffalo milk share of the wholesale trader was 27.82%. 9.82% and 8.36% and retailers were 18.18%, 14.54% and 18.19% for the same studied governorates, respectively. From the present results it can be concluded that dairy farms can get more profits if village cooperatives or farmers associations establish to collect milk from small dairy farms.
