The quality of crude glycerine influences the fermentation and nutritive value ...
Schwingel,Alice Watte; Fernandes,Tatiane; Orrico Junior,Marco Antonio Previdelli; Orrico,Ana Carolina Amorim; Lucas Junior,Jorge deABSTRACT We aimed to evaluate the effects of crude glycerine purity and levels of glycerol on the fermentative profile, microorganisms counting, and nutritional value of Piatã grass silage. The experiment was carried out in a 3×3+1 completely randomized factorial design using three different types of crude glycerine [low purity (40% of glycerol), medium purity (60% glycerol), and high purity (80% glycerol)], th...
The use of crude glycerin as an alternative to reduce fermentation losses and e...
Orrico Junior,Marco Antonio Previdelli; Velazquez Duarte,José Augusto; Crone,Carla; Neves,Franciely de Oliveira; Reis,Ricardo AndradeABSTRACT The objective of this study was to evaluate fermentation losses and the nutritional value of silage of Brachiaria brizantha cv BRS Piatã ensiled with different levels of crude glycerin. The experiment followed a 4 × 2 completely randomized factorial design with four doses of crude glycerin (0, 100, 200, and 300 g kg–1 of DM silage) and two cutting ages (45 and 60 days) with four replicates per treatmen...
Performance and methane emissions of Nellore steers grazing tropical pasture su...
Carvalho,Isabela Pena Carvalho de; Fiorentini,Giovani; Berndt,Alexandre; Castagnino,Pablo de Souza; Messana,Juliana DuarteABSTRACT The objective of this study was to evaluate the effect of lipid sources on voluntary intake, digestibility, performance, and CH4 emission of Nellore steers grazing Brachiaria brizantha cv. Xaraés forage in the dry season. Forty-five Nellore steers with average weight of 442±34 kg were alloted into one of the five treatments: without additional fat; with palm oil; with linseed oil; with protected fat; a...
Replacement of aruana grass by gliricidia (Gliricidia sepium) on silage quality
Massafera,Danilo Antonio; Florentino,Ligiane Aparecida; Rabelo,Carlos Henrique Silveira; Härter,Carla Joice; Rezende,Adauton Vilela deOur objective was to investigate the effect of the replacement of aruana grass by gliricidia on the fermentative losses, chemical composition, and aerobic stability of silages. For ensiling, whole-crop aruana grass (75 d of growth) was chopped (275 g kg-1 dry matter - DM) and ensiled alone or associated with gliricidia (270 g kg-1 DM; 150 d of growth). For gliricidia, we used only the leaves and stalks to ensil...
Effects of supplementation frequency on the ruminal fermentation and enteric me...
Canesin,Roberta Carrilho; Berchielli,Telma Teresinha; Messana,Juliana Duarte; Baldi,Fernando; Pires,Alexandre Vaz; Frighetto,Rosa Toyoko ShiraishiThe 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, and 12 cattle (399±32.6 kg BW) were used in the enteri...
Intake, performance and estimated methane production of Nellore steers fed soyb...
Messana,Juliana Duarte; Canesin,Roberta Carrilho; Fiorentini,Giovani; Reis,Ricardo Andrade; Arcuri,Pedro Braga; Berchielli,Telma TeresinhaThe objective of this study was to evaluate nutrient intake, performance, estimated methane production and carcass characteristics of steers fed diets containing three different levels of soybean grain: 0, 120 and 230 g/kg on the dry matter (DM). The study was conducted on eighteen castrated Nellore males with an average initial body weight (BW) of 370±12 kg in a completely randomized design, with three treatme...
Reducing supplementation frequency for Nellore beef steers grazing tropical pas...
Canesin,Roberta Carrilho; Berchielli,Telma Teresinha; Vega,Antonio de; Reis,Ricardo Andrade; Messana,Juliana Duarte; Baldi,FernandoReduced supplementation frequency is a broadly applied management practice. Ruminants consuming low quality forages/pastures, supplemented less than once daily are able to maintain body weight gain (BWG), efficiency of use of dry matter, nitrogen and other nutrients, as compared with animals supplemented once daily. We evaluated the feeding behavior, dry matter intake (DMI), dry matter and organic matter digest...
Hydrocyanic acid content and growth rate of sorghum x sudangrass hybrid during ...
Simili,Flávia Fernanda; Lima,Maria Lúcia Pereira; Medeiros,Maria Izabel Merino de; Paz,Claudia Cristina Paro de; Ruggieri,Ana ClaudiaIn central Brazil after soybean or other annual agricultural species is harvested, sorghum hybrids are planted in the fall in order to establish pastures for grazing animals. This study conducted for two consecutive years aimed at quantifying the contents of hydrocyanic acid in the leaves and determining plant height, forage dry matter yield and the leaf/stem ratio for sorghum hybrid 1P400 at different ages. St...
Rumen fermentation and rumen microbes in Nellore steers receiving diets with di...
Messana,Juliana Duarte; Berchielli,Telma Teresinha; Arcuri,Pedro Braga; Reis,Ricardo Andrade; Canesin,Roberta Carrilho; Ribeiro,Andressa FerreiraThe objective of the present study was to evaluate the effects of dietary lipid content (20, 40 and 60 g/kg dry matter) on intake, total and ruminal apparent digestibility of dry matter (DM), nutrient digestibility, rumen fermentation parameters, microbial synthesis efficiency and rumen microbial content of beef cattle. Nine cannulated steers at 6 months of age with initial body weight of 232±35 kg were used in...
Structural characteristics and forage mass of Tifton 85 pastures managed under ...
Silva,Wilton Ladeira da; Galzerano,Leandro; Reis,Ricardo Andrade; Ruggieri,Ana CláudiaThe experiment was carried out on Cynodon spp cv. Tifton 85 pastures grazed by sheep under rotational stocking, with the objective of evaluating the structural characteristics as well as the forage mass of the pastures subjected to three grazing intensities in successive cycles. Treatments were composed of three residual leaf area indices (rLAI; 2.4; 1.6 and 0.8), allocated in completely randomized blocks with ...
