Data were randomly collected from commercial sheep farms from different localities in Menofia governorate located in the south of Nile delta in Egypt. The data included seasons grouped into (cold season) extended from 21 September to 20 March and (warm season) from 21 March to 20 September to determine its effect on birth weight, litter size and kidding interval. The data were collected, summarized and analyzed by statistical computer program (SPSS/PC, 16). The results of the study revealed that warm season had higher parameters for birth weight, litter size and kidding interval than cold season as recorded 2.91 kg, 1.61 and 9.13 months. The manager characters has a significant effect on production of sheep farms as about 31% in production changes were attributed to the changes in demographic characters such as educational level and age of producer.

Goats were allocated into five treatment groups of varying levels of concentrate supplementation: Control (ad libitum access to elephant grass), 0.6% C (control plus 0.6% of concentrates), 1.2% C (control plus 1.2% of Concentrates), 1.8% C (control plus 1.8% of Concentrates) and 2.4% C (control plus 2.4% of Concentrates) as a percentage of liveweight on a dry matter basis. Growth and feed intake were measured in a 6 week feeding trial period after 3 week of initial adaptation. In vivo digestibility was assessed in the 10th week by the total faecal collection method. There were significant increases in average daily gain (ADG), feed intake and digestibilities of dry matter (DM), organic matter (OM) and crude protein (CP) as dietary concentrate levels increased. However, digestibility of neutral detergent fibre (NDF) was not different between the concentrate-supplemented groups. Pre-feeding ammonia concentration in rumen fluid was not different between treatments, but 4hrs after feeding, significant differences were detected. The values of ammonia ranged from 100-200 mg L⁻¹ at both times of measurement. Rumen fluid pH values were not different 4hrs post-feeding. Volatile fatty acid concentrations of propionate and butyrate increased with increasing levels of concentrates consumed, in contrast to decreased acetate concentration. This study clearly demonstrated that increasing concentrate levels offered to Bach Thao bucks up to 1.8% of live weight on a DM basis resulted in the greatest improvement in ADG, feed intake and nutrient digestibility, thus, confirming the tested hypothesis that increased level of concentrate supplementation will improve productive performance of goats without an adverse effect on rumen fermentation and nutrient digestibility.","PeriodicalId":14914,"journal":{"name":"Journal of Animal and Veterinary Advances","volume":"13 1","pages":"1173-1178"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70127468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Eight 87.5% Holsteinx12.5% indigenous multiparous cows were used in a crossover design with two successive 25 days periods. Diets contained 30% paragrass and 70% concentrate on a Dry Matter (DM) basis. Concentrate feeds were formulated to provide low dietary CP (17.3%; LCP) or high dietary CP (19.04%; HCP). The proportion of Rumen Degradable Protein (RDP) and RUP was 61 and 39% in both diets. Diets were isocaloric in terms of net energy for lactation. Milk yield, milk lactose yield, Dry Matter Intake (DMI) and apparent digestibility of DM, CP and Neutral Detergent Fiber (NDF) were greater in cows fed HCP than in those fed LCP. Concentration of blood urea nitrogen was elevated in cows fed HCP diets. Rumen NH3-N concentration and pH tended to increase in cows fed HCP diet. Rumen microorganism counts and volatile fatty acids levels in the rumen did not differ between treatments. The increasing CP content in mid-lactating cow was beneficial to increase DMI, apparent digestibility of DM, CP and NDF and therefore milk yield.","PeriodicalId":14914,"journal":{"name":"Journal of Animal and Veterinary Advances","volume":"13 1","pages":"9-14"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70127480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
