1. In vitro evaluation of novel crude extracts produced by actinobacteria for modulation of ruminal fermentation
ABSTRACT We evaluated the inclusion of two crude extracts produced by Streptomyces genus on in vitro dry matter and organic matter digestibility (IVDMD; IVOMD), cumulative gas production, volatile fatty acids (VFA), and methane (CH4) and ammoniacal nitrogen (NH3-N) concentration. The experimental design was randomized blocks with three blocks and four treatm

2. Fermentation characteristics and in vitro ruminal digestion of yacon residue silage with lactic acid bacteria inoculant or beet pulp
ABSTRACT In this study, we examined the effects of lactic acid bacteria (LAB) inoculant and beet pulp (BP) on the quality of yacon (Smallanthus sonchifolius) residue silage. Yacon silage was prepared using a small-scale system of silage fermentation, and the treatments were as follows: control silage without any additive and silages with LAB inoculant Chikus

3. Partial replacement of corn by soybean hulls in high-grain diets for feedlot sheep
Resumo: O objetivo deste trabalho foi avaliar a substituição parcial de milho por cascas de soja, em dietas de alta percentagem de grãos, e seu efeito sobre o comportamento alimentar e os parâmetros de fermentação ruminal em ovinos confinados. Oito carneiros com rúmens canulados foram distribuídos em quatro grupos experimentais, compostos de um contr

4. Crude glycerin combined with food additives in feeding beef cattle
ABSTRACT The objective of this study was to evaluate the effects of adding crude glycerin with food additives (sodium monensin or essential oils) to the diets of beef cattle on feed intake, ruminal parameters, in vitro digestibility, and production of greenhouse gases. Five ruminally cannulated Nellore steers were randomly assigned in a 5×5 Latin square des

5. The role of condensed tannins in ruminant animal production: advances, limitations and future directions
ABSTRACT Tannins represent one of the most abundant polyphenolic compounds in plants. Tannins exist as a multitude of chemically unique entities in nature. The most commonly occurring tannins are typically divided into two major classes based on chemical structure: hydrolysable (HT) or condensed tannins (CT). Hydrolysable tannins are esters of gallic or ella

6. Effect of the dietary level of cull pinto beans (Phaseolus vulgaris) on ruminal fermentation, kinetics, and digestibility of hair lambs
ABSTRACT The objective was to evaluate the effect of three levels of cull pinto beans (CPB; Phaseolus vulgaris) on ruminal fermentation, kinetics, and nutrient digestibility in hair lambs. Six cannulated lambs averaging 56.6±3.8 kg were used and were randomly assigned to one of three treatments. Treatments were: 0.0 kg kg−1 of CPB in the supplement (contr

7. Effect of calcium propionate and monensin on in vitro digestibility and gas production
ABSTRACT An evaluation of the effects of monensin and calcium propionate on the in vitro kinetics of gas production, digestibility, carbon dioxide, and minor gas production on different days was performed using the ruminal fluid from eight Suffolk lamb donors, after receiving additives for 1, 10, and 20 days. Treatments consisted of a control ration of 40% g

8. Additives on in vitro ruminal fermentation characteristics of rice straw
ABSTRACT The objective of this study was to evaluate the effects of mineral and protein-energy (MPES), exogenous fibrolytic enzyme supplements (ES), combination of MPES + ES, and straw without supplement (WS) on digestibility, fermentation kinetic parameters, cumulative gas production, methane, CO2 production, and volatile fatty acid concentration of rice st

9. Supplementation with corn oil and palm kernel oil to grazing cows: ruminal fermentation, milk yield, and fatty acid profile
ABSTRACT The effect of supplementation with corn oil (CO) and its mixture with palm kernel oil (CO:PKO 75:25) to grazing cows on ruminal fermentation, milk yield, and its fatty acid (FA) profile was evaluated. The treatments were: one control treatment (C) without oil and two treatments with 720 g d−1/cow of CO or CO:PKO (ether extract: 22.7 g kg−1 for c

10. Effects of supplementation frequency on the ruminal fermentation and enteric methane production of beef cattle grazing in tropical pastures
The objective of this study was to evaluate the characteristics of ruminal fermentation and enteric methane production in beef cattle subjected to different supplementation frequencies while grazing on Brachiaria brizanthacv. Marandu pastures. Nine cattle (325±65.7 kg BW) fitted with ruminal and duodenal cannulas were used in the ruminal fermentation study,

11. Methane emissions and estimates of ruminal fermentation parameters in beef cattle fed different dietary concentrate levels
Using sorghum silage, the effect of roughage/concentrate ratios was evaluated on nutrient intake, digestibility, ruminal parameters and methane production by beef cattle. Three treatments (0, 30 and 60% of concentrate in DM of the diet) were distributed in three Latin squares, with nine animals and three periods. Dry matter intake increased as the grain conc

12. Effect of tanniniferous plants and essential oils on methane emission in ruminants / Efeito de plantas taniníferas e óleos essenciais sobre a emissão de metano em ruminantes
Tannins and essential oils are secondary metabolites that may be used as natural modifiers of rumen fermentation to reduce the ruminants\ methane (CH4) emission. To study the application of tannin-rich plants from Egypt and Brazil, as well as essential oils that are available in international trade, three studies were conducted at Animal Nutrition Laboratory
