“…Lehloenya et al (2008b) Also found that feeding P169+yeast to cows increased production of actual milk and 4% FCM yield by 8.5-16.6% above control cows and this overall increase in milk yield was due to increased milk production during mid lactation (9-30 weeks). In contrast, Azzaz et al (2013a) found no significant differences among control and Aspergillus awamori supplemented buffaloes groups in milk composition and milk component's yields. Also, Morsy et al (2014) found that supplementing dairy buffalo's rations with Propionibacterium strain P169 did not affect milk yield or milk components.…”

“…In addition, Gaafar et al (2009) demonstrated that digestibility coefficients of all nutrients and nutritive values of experimental rations increased significantly by buffaloes treated with baker's yeast. Also, lactating buffaloes fed Aspergillus awamori supplemented rations showed higher DM, OM, CF, NFE digestibility and TDN value compared to those fed the control ration (Azzaz et al, 2013a). Farahat (2014) stated that supplemented lactating goat's diets with Lactobacillus acidophilus significantly improved all nutrients digestibility and nutritive values compared with those of control.…”

Improved ruminant's health and its productive performance has always remained a primary goal of researchers associated with the animal production sector. Microbial feed supplements as natural growth promoters might play an important role for enhancement of health and productive performance of ruminants through prevention of disease, enhancement of desirable microbial growth in the rumen environment, stabilization of ruminal pH, altered ruminal fermentation patterns, increased nutrient digestibility and flow of nutrients to the small intestine, improved nutrient retention and reduced stress through enhanced immune response. The definition of microbial feed supplements is very broad and may include specific and nonspecific yeast, fungi, bacteria, cell fragments and filtrates. The microbial feed supplements preparations must having a beneficial effect on the host animal (non-pathogenic and non-toxic), able to produce antimicrobial agents, antagonistic toward pathogenic, have ability to adhere and colonize the epithelial cells of the rumen and the gut, capable of compete with normal microflora and metabolizing in the gut environment and genetically stable and capable of remaining viable for long periods under storage and field conditions. The use of microbial feed supplements continuously may decrease the harmful effects of the pathogenic bacterial species in the ruminant digestive system and thereby improve the animal performance.

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.

“…Blood glucose was reported to be numerically higher in Holstein calves fed varying milk replacers (MR) with direct-fed microbial (Geiger et al, 2014). Similarly, the difference in plasma glucose (72.17-74.11 mg/ dl) of lactating buffalo was not significant on feeding rations with two types of fibrolytic enzyme at 2 g/kg DM (Azzaz et al, 2013). It was also non-significant in lactating Murrah buffaloes fed fibrolytic enzymes at 1.5 and 3.0 g/kg DM (Shekhar et al, 2010).…”

Twenty crossbred (HF x Kankrej) calves were allotted randomly to five groups (each had one male and three female calves) almost with similar body weight (85.70±6.37 kg) and age (167.55±21.70 days). Experimental calves of the control group were offered hybrid napier untreated, and the other four groups were offered hybrid napier treated with (i) fungus- Aspergillus spp. (1×107 per g feed), (ii) fibrolytic bacteria- Escherichia spp. (106 CFU per g feed), (iii) xylanase (50 mL/kg having xylanase 1.2 IU/mL), and (iv) consortium of 1/3rd dose of fungus + bacteria + enzyme as treatments for 140 days. The blood samples were collected from each calf at a biweekly intervals in the EDTA vacuttee. Nutrients offered to crossbred calves were sufficient to satisfy the nutrients requirements. Bacteria fed calves had significantly higher (plessthan0.05) mean hemoglobin levels than control. Blood plasma glucose of calves in fibrolytic microbes and enzyme groups was statistically similar to control. Feeding of fungus, bacteria, enzyme, and consortium was without a significant effect on plasma total proteins.In comparison to control (7.53 mg/dL), the plasma phosphorus was significantly (plessthan0 0.05) higher in calves fed enzyme (7.87 ± 0.20 mg/dl) and lower in group fed fungus (7.13 mg/dL). In contrast, in bacteria (7.57 mg/dL) and consortium group (7.60 mg/dL) it was statistically similar to control. Plasma glutamic pyruvic transaminase concentration of crossbred calves was lower ( pless than 0.05) in enzyme and higher (p lessthan 0.05) in fungus, bacteria, and consortium groups than in control, while plasma glutamic oxaloacetate transaminase concentration in all groups was statistically similar. In conclusion, all blood parameters of different groups were within normal range and without adverse effect on the overall performance of calves.
