This study aimed to evaluate the association of technical cashew nut shell liquid (tCNSL) and two sources of non-protein nitrogen (NPN), dry matter intake (DMI), the partial and total apparent digestibility coefficient of nutrients, ruminal fermentation, microbial synthesis, and blood characteristics. Four Holstein steers (438 kg ± 17.14 kg) fitted with ruminal and duodenal cannula were used. Diets had (in DM b...
To evaluated the chemical composition and ruminal degradability of crambe byproducts (meal and crushed) and proteic supplements formulated with crushed crambe (0; 2.5; 5; 10 and 15%); five crossbred steers with average weight of 485±14 kg, were used. All the animal were kept in individual paddocks of 0.25 ha on Urochloa brizantha (syn. Brachiaria brizantha). It was observed a greater soluble fraction, high...

The study evaluated the effects of supplementing cashew nut shell liquid (CNSL) in the diet of lactating dairy cows on the intake, nutrient digestibility, milk yield and composition, and fatty acids composition of milk fat. Four Holsteincows (600±43 kg) were used in a 4 x 4 Latin square design with 21 days experimental periods. Experimental treatments consisted of CNSL inclusion in a total mixed ration (dry mat...
It was aimed to evaluate the ruminal degradability, and the fractioning of carbohydrates, as well as of the nitrogen fractions of triticale silages in singular culture or in mixtures with oats and/or legumes. The treatments had been: triticale silage (X. Triticosecale Wittimack) (ST); triticale silage + forage pea (Pisum arvense) (STE); triticale silage + oats (Avena strigosa Scheb) + forage pea + vetch (Vicia ...
The present study used meta-analysis to assess the effects of supplementation on beef cattle performance in pastures in Brazil, classifying data by season of the year. There were reviewed articles published in journals indexed from 1999 to 2007. There were used 70 articles and data were grouped according to season of the year (Rainy, Drought, Transition Rainy/Drought and Transition Drought/Rainy). It was done c...
Five Holstein steers weighting 450 kg were used in a 5 x 5 Latin square statistical design, where treatments consisted of five replacement levels: 0, 25, 50, 75 and 100% of urea by ammonium chloride, as non-protein nitrogen in the diet. There was a linear decrease (p < 0.05) on intake and fecal flow, as well as a linear increase in apparent digestibility of DM, OM, CP, NDF and EE as result of ammonium chloride ...
The trial was performed to evaluate the effect of phosphorus sources on forage mass quality of Mombaça grass (Panicum maximum Jacq. cv. Mombaça), according to in vitro dry matter and organic matter digestibility and TDN concentration. Every month, samples of available forage mass were taken, from December, 2002 until April, 2003. The treatments were three phosphate sources (1-YoorinÆÊ magnesium thermophosphate;...
Thirty-two steers, fourteen months old and average initial weigh 345 kg were used. Forage production, quality and animal performance were evaluated in a four hectare area of coastcross pasture during wet season. Steers were supplemented with two energy sources: soybean hulls (SH) and oat grains (OG). Animals were allotted in four treatments: without supplement (WS), 0.6% of body weight (BW) with OG, 0.6% of BW ...
