Manipulation of rumen environment using herbal mixtures with antioxidant and antibacterial potentials will improve rumen health and animal productivity. This study undertook to assess the effect of supplementing garlic and ginger powder and their combination on rumen ecology and nutrient utilization of sheep. Sixteen mixed breed rams were allotted to four experimental diets in a completely randomized design. The experiment lasted for 91 days. The four diets were Control (No garlic or ginger powder), gap (garlic powder 2.5 g/kg diet), gip (ginger powder 2.5 g/kg diet) GGP (garlic powder 1.25 g/kg diet + ginger powder 1.25 g/kg diet). Data on rumen ph, metabolites, microbial count, and isolation, nutrient digestibility was statistically analyzed using one-way analysis of variance as provided in the GLM of SPSS (version 23). Results revealed an increase (p<0.05) indaily weight change, rumen total volatile fatty acids (tvfas), acetate, propionate and butyrate, bacteria count, gram-negative bacteria, fungi species such as Rhizopus sp., apparent digestibilities of dry matter (DM), ash, NDF and ADF with supplementation of garlic and/or ginger and their combination. The combination of garlic and ginger gave a comparative better (p<0.05) result in some of the parameters than either garlic or ginger singly. It was concluded that a combination of 1.25 g/kg diet of garlic and ginger each would achieve an overall better performance of the rumen that feeding 2.5 g/kg diet of garlic or ginger singly. La manipulation de l'environnement du rumen à l'aide de mélanges d'herbes aux potentiels antioxydants et antibactériens améliorera la santé du rumen et la productivité animale. Cette étude a entrepris d'évaluer l'effet de la supplémentation en poudre d'ail et de gingembre et leur combinaison sur l'écologie du rumen et l'utilisation des nutriments des moutons. Seize béliers de races mixtes ont été attribués à quatre régimes expérimentaux dans une conception complètement aléatoire. L'expérience a duré 91 jours. Les quatre régimes étaient Contrôle (sans ail ni gingembre en poudre), le 'gap' (ail en poudre 2.5 g / kg régime), le 'gip' (gingembre en poudre 2.5 g / kg régime) le 'GGP' (ail en poudre 1.25 g / kg régime + gingembre en poudre 1.25 g / kg régime). Les données sur le pH du rumen, les métabolites, la numération microbienne et l'isolement, la digestibilité des nutriments ont été analyses statistiquement en utilisant une analyse unidirectionnelle de la variance telle que fournie dans le GLM de SPSS (version 23). Les résultats ont révélé une augmentation (p <0.05) du changement de poids quotidien, des acides gras volatils totaux du rumen (tvfas), de l'acétate, du propionate et du butyrate, du nombre de bactéries, des bactéries gram-négatives, des espèces de champignons comme Rhizopussp., Des digestibilités apparentes de la matière sèche, cendres, le 'NDF' et le 'ADF' avec supplémentation en ail et / ou gingembre et leur combinaison. La combinaison d'ail et de gingembre a donné un meilleur résultat comparative (p <0.05) pour certains des paramètres que l'ail ou le gingembre seuls. Il a été conclu qu'une combinaison de 1.25 g / kg de régime d'ail et de gingembre chacun permettrait d'obtenir une meilleure performance globale du rumen qu'une alimentation de 2.5 g / kg d'ail ou de gingembre séparément.
Egyptian Journal of Veterinary Scienceshttps://ejvs.journals.ekb.eg/ 29 P OOR quality forages such as mature grass could be improved by physical, chemical and biological treatment. One of such procedure is supplementing with feed that will modify the rumen environment to improve forage utilization. A 90-day study was conducted to examine the rumen ecology of semi-intensively raised West African Dwarf (WAD) goats fed supplemented concentrate diet containing incremental levels of sodium humate. The thirty (30) WAD bucks (age 10-15 months) used in this study were randomly assigned to five dietary treatments containing 0, 5, 7.5, 10 and 12.5 g/kg diet of sodium humate in a completely randomized design. Data were obtained on rumen pH, ammonia nitrogen, total volatile fatty acids (VFA) and some of their various proportions (Acetate, propionate and butyrate), protozoa, fungi and bacteria counts and were statistically analysed using the GLM procedure of SPSS (version 23). Results revealed that pH, NH3-N, and fungi count were affected (p<0.05) by the inclusion of sodium humate in the diets. However, volatile fatty acids and the various proportions, protozoa and bacteria counts were not affected (p>0.05) by the inclusion of sodium humate in the diets. It was concluded that sodium humate could be used in the diet of semi-intensively managed WAD goats to stabilize the rumen pH and that levels up to 10 g/kg diet could be utilized to improve fungi count.
