The aim of this study was economic evaluation and investigation of some factors such as season and demographic characters (manager characters) on some productive and reproductive efficiency in sheep production farms under Egyptian conditions. 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.

Twenty-five Bach Thao bucks (7 months old and 20.9±0.3 kg BW) were used to quantify the effect of concentrate supplementation on growth performance, rumen volatile fatty acid profile, digestibility and plasma metabolites. 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.
选用25头7月龄、体重20.9±0.3 kg的巴氏雄鹿，量化添加精料对其生长性能、瘤胃挥发性脂肪酸谱、消化率和血浆代谢物的影响。将山羊分为5个精料添加水平不同的处理组:对照(随意取用象草)、0.6% C(对照加0.6%精料)、1.2% C(对照加1.2%精料)、1.8% C(对照加1.8%精料)和2.4% C(对照加2.4%精料)(按干物质基础计算)。初试期3周后，在6周的正试期内测定生长和采食量。第10周采用全粪收集法评估体内消化率。随着饲粮精料水平的升高，平均日增重(ADG)、采食量以及干物质(DM)、有机物(OM)和粗蛋白质(CP)的消化率均显著升高。而中性洗涤纤维(NDF)消化率在精料补充组之间无显著差异。饲喂前各组间瘤胃液氨浓度差异不显著，但饲喂后4h差异显著。在两次测量中，氨的值在100-200 mg L - 1之间。饲喂后4小时瘤胃液pH值无差异。丙酸和丁酸挥发性脂肪酸浓度随浓缩物消耗水平的增加而增加，而乙酸浓度则降低。本研究清楚地表明，以日增重为基础，将精料添加水平提高至巴赫雄鹿活重的1.8%时，平均日增重、采食量和营养物质消化率的改善最大，从而证实了试验假设，即增加精料添加水平可以提高山羊的生产性能，而不会对瘤胃发酵和营养物质消化率产生不利影响。

An experiment was conducted to investigate the effects of 2 levels of dietary Crude Protein (CP) in concentrates with similar proportions of Rumen Undegradable Protein (RUP) on rumen metabolism, milk yield and composition in mid lactating cows in Thailand. 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.
