  This experiment was designed to study the effects of dietary addition of some essential oils on ruminal fermentation characteristics, blood parameters milk production and milk composition. Twenty lactating Damascus goats, seven days after parturition, were assigned randomly into four groups (five animals each) using complete randomized block design. Experimental period lasted for 90 days. Goats of each group were fed the same basal diet and received one of the following treatments; (C) control (without oil), (ANI) control diet+2 mL Anise oil/head/day (mL/h/d), (CLO) control diet+2 mL Clove oil/h/d, (JUN) control diet+2 mL Juniper oil/h/d. Ruminal Total Volatile Fatty Acids (TVFA) has achieved an increase while, ammonia nitrogen was decreased with Essential Oils (EO) additives. Values of serum total protein and globulin have recorded the highest concentrations, on the contrary, blood urea nitrogen and cholesterol concentrations were recorded the lowest values with EO additives. Milk yield and milk composition were not significantly affected by EO additives, while milk fat and milk non-protein nitrogen contents which decreased with EO additives and milk protein content increased with EO additives compared to control. Goats fed diet supplemented with Juniper oil produced milk fat have highest value of total and individual Conjugated Linoleic Acids (CLA) and C18.3N3 (omega 3). Results from this study suggested that feeding these EO (2 g/h/d) to lactating dairy goats had limited effects on milk production and milk composition but feeding 2 mL Juniper oil/h/d changed milk fatty acids profile for healthy effect on the consumers.

  This study was conducted to study the effect of yeast culture (Saccharomyces cerevisiae) supplementation either alone or in combination with Propionibacterium freudenreichii strain P169 on nutrient digestibility coefficients, blood metabolites, milk yield and milk composition of mild lactating buffaloes. Fifteen lactating buffaloes, 2 months after parturition, were randomly assigned into three groups, 5 animals each, using complete random design. The experiment lasted for two months, buffaloes were fed dry matter according to 3% of their mean body weight. The experimental groups were fed on: (1) Control ration (consisted of 50% concentrate feed mixture (CFM), 30% corn silage, 10% dried sugar beet pulp and 10% rice straw), (2) Control ration+50 g Yeast Culture (YC)/head/day and (3) Control ration+50 g YC+4 g propionibacteria, P169, (YC+P169)/head/day. The supplementation of YC or YC+P169 improved (p<0.05) all nutrients digestibility but significantly decreased (p<0.05) blood plasma urea nitrogen of treated buffaloes. Milk and 4% fat corrected milk yields were significantly increased (p<0.05) while milk fatty acids were unaffected by YC or YC+P169 supplementation. In conclusion, ration’s supplementation with YC or YC+P169 had beneficial effects on the buffaloes productivity with no deleterious effects on animals health.

  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.

  Two experiments were carried out to evaluate the effects of fibrolytic enzymes supplementation on in vitro degradation of sugar beet pulp and in vivo nutrients digestibility, milk yield and its composition by mild-lactating buffaloes. In the in vitro experiment, dry matter and organic matter disappearance (IVDMD and IVOMD) were determined for sugar beet pulp supplemented separately with laboratory produced fibrolytic enzymes (Asperozym) and commercial fibrolytic enzymes source (Tomoko®) at 3 levels (0, 1, 1.5 and 2 g kg-1 DM). Increasing the Asperozym and Tomoko® supplementation levels up to 2 g kg-1 DM exhibited the highest (p<0.05) values of IVDMD and IVOMD. In the in vivo experiment, fifteen mild-lactating buffaloes after 3 months of parturition were divided into three groups, five animals each, using complete random design. The first group was fed on 45% Concentrate Feed Mixture (CFM), 30% corn silage ,15% dried sugar beet pulp and 10% rice straw (control ration). The second group was fed control ration supplemented with Asperozym at 2 g kg-1 DM (R1), while the third group was fed control ration supplemented with Tomoko® at 2 g kg-1 DM. (R2). Asperozym and Tomoko® supplementation significantly (p<0.05) increased DM, OM, CF, NFE, NDF digestibility for treated groups compared with the control group, while blood plasma parameter , milk yield and its composition did not significantly (p<0.05) change among all groups.
