  The objective of the present study was to investigate the effect of inclusion different types of forage in dairy buffaloes rations on the performance of milk production. Twelve multi parous Egyptian buffaloes, after 8 weeks of calving (averaged 550 kg live body weight) were assigned into three groups of 4 buffaloes in 3x3 Latin square design. Each group fed one of the three rations with different kind forage either berseem (R1), berseem plus corn silage (R2) or corn silage (R3). All groups were fed forage plus Concentrate Feed Mixture (CFM) by 50% concentrate: 50% roughage. The digestibility coefficients of DM, CP, CF and cellulose were significantly higher for R1 compare to other tested rations. However, no significant differences noticed among tested rations for OM, EE, NFE, NDF, ADF and hemicelluloses. All tested rations, had nearly similar values of TDN and DE. R1 contained (B) had the highest DCP value (11.81%) followed by R2 (10.25%) contained (B+CS) while R3 contained (CS) had the lowest value (8.63%). No significant differences among the tested groups in both actual and 7% FCM yields. In addition, there were insignificant differences between animals fed all tested rations in lactose, ash and SNF of milk produced. While feeding both kinds of forages (B+CS) and CFM (R2) were significantly increased fat, protein and TS contents compared with feeding R1 and R3. No significant differences were observed among tested groups for feed efficiency as the amount of DM required to produce one kg 7% FCM. While highly significant differences among treatments were detected concerning DCP efficiency. Normal ranges for the blood parameters were observed with no significant differences as the result of feeding all tested rations. Short chain fatty acids were significantly higher with ration contained berseem compared to with rations contained corn silage which had higher values in long chain fatty acids.

  The main objective of the current study is to evaluate tomato pomace silage as a source of roughage feed for lactating animals. Twenty lactating Egyptian buffaloes at the second/third season of lactation were used in the present study. The animals were randomly divided to two groups (ten buffaloes in each) using the complete random design. The animals were introduced to treatments starting on 70 DIM and continued for six weeks. The treatments were, control ration (R1) and it received a Corn Silage (CS) based ration supplemented with Concentrate Fed Mixture (CFM), Clover (C) and Rice Straw (RS) without Tomato Pomace Silage (TPS). The second ration (R2) was similar to the ration in first group with replacing clover by tomato pomace silage. The digestibility coefficients of dry matter, neutral and acid detergent fiber and nutritive values were increased (p<0.05) significantly with tomato pomace silage feeding. The protein and cellulose digestibility coefficients was negatively influenced (p<0.05) by tomato pomace feeding. The feeding of tomato pomace did not alter actual milk yield but it increased (p<0.05) 7% fat-corrected milk yield and milk fat percentage. Other milk composition percentages were not significantly affected. Feeding tomato pomace increased (p<0.05) proportions of polyunsaturated fatty acids, however, milk protein amino acid fraction was negatively affected in most cases. Inclusion of tomato pomace silage in the ration of lactating buffaloes improved feed utilization and economic efficiency compared to control ration. It was concluded that the nutritional value, feed conversion and economic efficiency of rations contained tomato pomace silage improved when used at rate 25% of ration without any adverse effect on performance of lactating buffaloes.

  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: 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.

  Pionibacteria are natural inhabitants of the rumen that make up 1.4% of ruminal microflora and produce propionate, a major precursor for glucose production by hepatic gluconeogenesis. Several mechanisms have been suggested for the mode of action of direct-fed bacteria in ruminants include stimulation of desirable microbial growth in the rumen, alteration of ruminal fermentation pattern and end product formation, increasing postruminal nutrient flow, increasing nutrient digestibility and alleviation of stress through enhanced immune response. Propionibacteria have the ability to convert lactic acid and glucose to acetic and propionic acids, reduce the risk of acidosis and increase weight gain and milk production of treated animals. On the other hand, enteric CH4 is the single largest contributing source of greenhouse gases production which causes global warming crisis. Propionibacteria also act to alter the biohydrogenation of polyunsaturated fatty acids in the rumen and increasing the generation of health-promoting fatty acids such as Conjugated Linoleic Acid (CLA). The impact of feeding of propionibacteria on the performance of the ruminant animals has been evaluated but results were inconsistent, this may be attributed to many of factors involved the used bacterial strain and its viability, bacterial inclusion level in the diet, diet composition and frequency of feeding, animal status including age, breed, health and physiological condition. In this review the focus will be on surveying impact of feeding propionibacteria on the productive performance of the ruminants including the effects on nutrients digestibility, rumen activity, blood parameters, milk yield and milk composition.
