Influence of a blend of functional oils or monensin on nutrient intake and digestibility, ruminal fermentation and milk production of dairy cows
(2016-09-01)
Cashew nut shell liquid (CNSL) and castor oil (CO) are considered functional oils since they present antitumor, antioxidant, gastroprotective, and antibiotic properties. The objective of this study was to evaluate the ...
Potencialidades da utilização de taninos na conservação de forragens e nutrição de ruminantes-revisão
(2007-11-21)
This review present a discussion abouth the tannins. The tannins are compounds that have the ability to bind other macromolecules, reducing their availability to animal metabolism. This characteristic can be benefic or ...
Effect of replacing soybean meal with urea or encapsulated nitrate with or without elemental sulfur on nitrogen digestion and methane emissions in feedlot cattle
(2019-11-01)
The objective of this study was to investigate the replacement of a true protein source (soybean meal, SBM) with non-protein nitrogen (NPN) sources (urea, U; or encapsulated nitrate (NO3 −), EN) and corn with or without ...
Zebu cattle fed dry distiller’s grain or cottonseed meal had greater nitrogen utilization efficiency than non-supplemented animals
(2022-04-01)
This study evaluated intake, apparent digestibility, ruminal parameters, nitrogen balance, and microbial protein synthesis in grazing beef cattle fed a mineral mix or combination of two coproducts (cottonseed meal and dried ...
Consumo e digestibilidade em bovinos em pastejo durante o período das águas sob suplementação com fontes de compostos nitrogenados e de carboidratos
(Sociedade Brasileira de Zootecnia, 2011-08-01)
Objetivou-se avaliar os efeitos de diferentes formas químicas de compostos nitrogenados (proteicos e não-proteicos) e de carboidratos (amiláceos e fibra solúvel) sobre o consumo, a digestibilidade e a síntese ruminal de ...
Effect of different levels of concentrate on ruminal microorganisms and rumen fermentation in Nellore steers
(Taylor & Francis Ltd, 2016-01-02)
The aim of this study was to investigate the effect of different dietary levels of concentrate on feed intake, digestibility, ruminal fermentation and microbial population in steers. Eight Nellore steers fitted with ruminal ...
Aditivos na ensilagem do capim-elefante. IV. Fermentação ruminal em ovinos
(1998-12-01)
The ruminai fermentation patterns of sheep fed elephant grass (Pennisetum purpureum Schum.) silage enriched with ground ear corn with husks, wheat bran and saccharin in the levels 0, 8, 16 and 24% dry weight of additive/wet ...
Eficiência de síntese microbiana e atividade enzimática em bovinos submetidos à suplementação com enzimas fibrolíticas
(Sociedade Brasileira de Zootecnia, 2006-06-01)
Avaliou-se o efeito da suplementação com enzimas fibrolíticas (celulase e xilanase) sobre a eficiência de síntese microbiana e a atividade enzimática da beta-1,4-endoglucanase (celulase) em animais consumindo dietas contendo ...
Effects of protein sources and inclusion levels on nitrogen metabolism and urea kinetics of Nellore feedlot steers fed concentrate-based diets
(2021-08-01)
Urea recycling occurs in all mammalian species and represents an important source of ruminal nitrogen (N) for ruminants fed protein-restricted diets. However, its importance for cattle fed adequate amounts of protein and ...
Use of protected fat sources to reduce fatty acid biohydrogenation and improve abomasal flow in dry dairy cows
(2017-02-01)
The objective of this study was to evaluate the effects of dietary fat supplementation on dry dairy cows feed intake, digestion, ruminal kinetics, biohydrogenation, and abomasal flow of fatty acids (FAs). Eight Holstein ...
