  Background: Synchronization the rate of which dry matter and crude protein degraded at the rumen significantly affects the synthesis of microbial protein and thus the efficiency of feed utilization. During previous study a new software application "Lacto-sheep" had been developed to facilitate the formulation of the least cost ration considered this important factor. So that formulation of a synchronous least cost ration is possible and not difficult. This study was carried out to investigate the advantages of feeding synchronous least cost ration as an alternative to the traditional least cost ration on nutrients digestibility and milk production and its constituents. Materials and Methods: The kinetics of dry matter and crude protein disappearance and approximate analysis were determined for each feed ingredients used. Then, using our feed formulation software "Lacto-Sheep" two diets; traditional least cost and synchronous least cost ration were formulated and fed to two groups of multiparous lactating Barki ewes (5 ewes each), suckling single with an average body weight (35.10±2.50 kg) using completely random design. Experiment started 2 weeks after lambing and lasted 60 days. Results: The synchronous least cost ration contained variety of protein sources compared with the least cost ration, which did not contain any rich source of protein (soya bean or cotton seed meal) that’s because the cost of feed is the main limiting factor regardless optimizing feed utilization. Digestion coefficient of crude protein was slightly improved in group fed synchronous least cost ration. In addition, milk production and its components were also slightly higher. However, the differences were not significant. Conclusion: Based on the results obtained from this study, synchronous least cost ration seemed to be more practically appropriate ration for feeding lactating Barki ewes.

  Background: The current study was carried out to investigate addition of lemongrass or galangal to diet and its effect of productive performance of lactating Barki goats. Materials and Methods: Thirty lactating Barki goats were divided into three groups (10 animals per each treatment), first group was fed control diet without additives, consist of Egyptian clover hay, corn silage and concentrate feed mixture (10:30:60% on DM basis, respectively) (Control); second group was fed control diet plus 4 g of lemongrass kg–1 DM and the third group was fed control diet plus 4 g galangal kg–1 DM.Results: The results showed that adding galangal increased propionate concentrations (p<0.05) compared with control (41.13, 37.75 and 39.46 mM for galangal, control and lemongrass, respectively); while, there were no differences (p>0.05) between treatments in acetate and butyrate concentrations. Ammonia concentration was higher (p<0.05) in lemongrass compared with other treatments (21.49, 15.92 and 15.91 mM for lemongrass, control and galangal, respectively). Milk yield were significantly increased (p<0.05) by adding lemongrass or galangal to the diets (825 and 771 g day–1 for lemongrass and galangal) compared with control (652 g day–1 ). Also, milk lactose content was significantly increased (p<0.05) in lemongrass compared with control (44, 40 and 39 g kg–1 for lemongrass, control and galangal, respectively). Conclusion: It could be concluded that adding lemongrass or galangal the diet could enhance the performance of lactating Barki goat.

  Background and Objective: Utilization of date seeds (processed date by product) as a feedstuff in diets of farm animals are being in spotlight, this study were carried out to investigate the effect of feeding diets contain cracked date seed with or without fibrolytic enzyme, versus control diet using Egyptian buffaloes. Materials and Methods: Fifteen multiparous lactating Egyptian buffaloes (600±30 kg BW) were randomly assigned for 90 days in a completely randomized experimental design. Buffaloes were randomly assigned to 3 groups and fed a basal diet of concentrates, Egyptian clover and rice straw in a ratio of 50:30:20 DM basis (T1), the second group fed (T2) concentrate feed mixture, cracked date seed, Egyptian clover and rice straw as 35:15:30:20, respectively and the third group fed as T2 diet plus fibrolytic enzyme. Results: T2 groups had reduced feed intake (p>0.09) and DM, OM, NDF and ADF digestibility (p<0.05) than control (T1). While, T3 improved fiber digestion (NDF and ADF) compared with T2, with no differences with control (T1). Similarly, T2 resulted in lower (p<0.05) daily milk yield, energy corrected milk and milk efficiency (p<0.05) compared with T1, whilst, T3 improved the milk yield and ECM and milk efficiency compared with T2 (p<0.05) but without differences with T1 (p<0.05). Conclusion: It could be concluded that using cracked date seed with fibrolytic enzymes in lactating buffalo's diet improved feed conversation and productive performance with no negative effect on animal health.
