This study aimed to investigate the impact of repeated acidosis challenges (ACs) and the effect of live yeast supplementation (Saccharomyces cerevisiae I-1077, SC) on rumen fermentation, microbial ecosystem and inflammatory response. The experimental design involved two groups (SC, n=6; Control, n=6) of rumen fistulated wethers that were successively exposed to three ACs of 5 days each, precede...

Choline is a vitamin-like substance it has multi-function in animal production, reproduction, and health. The transition period is most crucial stage in lactation cycle of dairy cows due to its association with negative hormonal and energy balances. Unfortunately, unprotected choline easily degrades in the rumen; therefore, choline added to the diet in a rumen-protected form. The use of rumen-p...

the aim of this study was to determine effects of different fatty acid profiles on rumen digestion coefficients, some of rumen metabolism parameters and rumen microbial populations. different oils were used as source of fatty acids such as, oleic, linoleic, linolenic, dha and epa. palmitic acid supplemented from a commercial product (bergafat t-300) containing high palmitic acid percentage. res...

B complex vitamins play an important role in the metabolism of carbohydrates, proteins and fats. The aim of this study was to determine the effects of B complex vitamins administered by exogenous route on rumen protozoa, hematological and blood biochemical parameters in clinically healthy cattles. Thirty cattles aged between 6 to 18 months, and breeding in Afyonkarahisar Province and surroundin...

This study was conducted to determine in vitro crude protein degradation (IVDP) parameters and effective crude protein degradability (EPD) of various feeds using the modified in vitro gas production (GP) technique. Feed samples were alfalfa hay, soybean meal, soybean, rapeseed meal, sunflower meal and fish meal. Rumen fluid was collected before the morning feeding from four rumen fistulated lam...

the effect of the substitution of imported raw materials (corn and soyabeans) by local food resources (barley, white sorghum, triticale and horse bean) on the parameters of faciesfermentation and digestibility in the rumen of sheep was evaluated. four sicilo-sarde rams 4.8±0.5 years of age with an average live weight of 45.25±3.5 kg, permanently canulated in the rumen and housed in individual c...

The objective of the present study was to determine whether β1-4 galacto-oligosaccharides (GOS) and Candida kefyr combined with nitrate as manipulators could suppress rumen methanogenesis without nitrate poisoning in sheep. Four rumen fistulated wethers were allocated to a 4×4 Latin square design. Nitrate (1.3 g NaNO3 kg body weight) with and without GOS and Candida kefyr were administered into...
