  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.

  Background and Objectives: Supplementing diets of dairy animals with phytase and xylanase can enhance phosphorus availability and fiber degradation in the rumen and positively affect animal’s health and productivity. In vitro and in vivo trials have been conducted to define the optimal addition level of xylanase and phytase to lactating Baldi goat’s rations and investigate effects of these enzymes on animal’s nutrients digestibility, blood chemistry, milk production and milk composition. Materials and Methods: In vitro batch culture technique was used to evaluate the effect of phytase and xylanase supplementation at different levels (0, 1, 2 and 3 g kg1 DM) on rumen fermentation characteristics. Eighteen early lactating Baldi goats were randomly assigned into three groups and fed 4% dry matter according to their body weight. The first group was fed control ration (35% yellow corn, 20% corn stalks, 20% berseem hay, 12.5% soybean meal and 12.5% wheat bran), the second group fed control ration+Penizyme at 2 g kg1 DM (R1), while the third group fed control ration+Phtase-Plus® at 1 g kg1 DM (R2). Results: Xylanase and phytase supplementation increased the in vitro DM and OM degradability and ruminal NH3-N and total volatile fatty acids (TVFA) concentrations, with no effect on total gas production (TGP) volume. All nutrients digestibility (except CP), blood serum glucose concentration, milk production and milk components yields were increased for enzymes supplemented goats than control. Conclusion: Inclusion of xylanase and phytase in lactating goat’s rations improved their productive performance with no deleterious effects on their health.
