Ingestive Behavior of Ovine Fed with Marandu Grass Silage Added with Naturally Dehydrated Brewery Residue.

The objective was to evaluate the ingestive behavior of ovine fed Marandu grass silage with dehydrated brewery residue added. The experiment had a completely randomized design with five treatments and four repetitions, with the treatments levels of inclusion being of 0, 10, 20, 30, and 40% natural matter of naturally dehydrated brewery residue for 36 hours to the marandu grass silage. 20 ovines were used and the experimental period was 21 days, 15 being for adaptation to diets. The use of brewery byproduct promoted quadratic effect (P < 0.05) for the consumption of dry matter with maximum point value estimated at adding 23.25% additive. Ingestion efficiency and rumination efficiency of dry matter (g DM/hour) were significant (P < 0.05), by quadratic behavior, and NDF ingestion and rumination efficiency showed crescent linear behavior. The DM and NDF consumption expressed in kg/meal and in minutes/kg were also significant (P < 0.05), showing quadratic behavior. Rumination activity expressed in g DM and NDF/piece was influenced (P < 0.05) by the adding of brewery residue in marandu grass silage in quadratic way, with maximum value estimated of 1.57 g DM/bolus chewed in inclusion of 24.72% additive in grass silage. The conclusion is that intermediary levels adding of 20 to 25% dehydrated brewery residue affects certain parameters of ingestive behavior.

Inclusion of different levels of common-bean residue in sheep diets on nutrient intake and digestibility / Inclusão de diferentes níveis do resíduo de feijão nas rações de ovinos sobre o consumo e digestibilidade dos nutrientes

The objective of this study was to evaluate the effect of including common-bean residue in diets for feedlot sheep on the intake and digestibility of nutrients by these animals. Sixteen intact male sheep were allotted in a completely randomized design with four treatments and four replicates. Treatments consisted of the inclusion of 0, 11, 22, and 33% of the common-bean residue (dry matter basis) in the experimental diets, which corresponded to the substitution levels of 0.0, 33.3, 66.7, and 100.0% of cottonseed cake for the bean residue. Data of the studied variables were subjected to analyses of variance and regression, adopting a significance level of 5%. The model was chosen based on the significance of the regression parameters, evaluated by the t test (P<0.05), and on the coefficients of determination. The levels of inclusion of the common-bean residue in the diet influenced (P<0.05) the intakes of dry matter (DM), crude protein, organic matter, ether extract, and indigestible neutral detergent fiber, expressed in g animal-1 day-1, percentage of body weight (%BW), and metabolic weight (BW0.75), which decreased linearly. However, the inclusion of the different levels of common-bean residue did not change (P>0.05) the intakes of neutral detergent fiber, non-fiber carbohydrates, or total digestible nutrients by the feedlot sheep. Every 1.0% of inclusion of the common-bean residue in the sheep diet led to a reduction of 4.93, 0.01, and 0.20 in DM intake when expressed in g animal-1 day-1, %BW, and BW0.75, respectively. Every 1.0% of inclusion of the bean residue resulted in the reduction of 2.73% in the intake of indigestible neutral detergent fiber by the feedlot sheep. Sheep displayed a linear increase (P<0.05) in water intake with the levels of common-bean residue in the experimental diets.[...](AU)

Objetivou-se avaliar o efeito da inclusão do resíduo de feijão na dieta de ovinos confinados sobre o consumo e a digestibilidade dos nutrientes. Foram utilizados 16 ovinos, machos inteiros, distribuídos em um delineamento inteiramente casualizado, com quatro tratamentos e quatro repetições. Os tratamentos foram constituídos pela inclusão de 0; 11; 22 e 33% na MS do resíduo de feijão nas dietas experimentais, as quais corresponderam aos níveis de substituição de 0,0; 33,3; 66,7 e 100,0% da torta de algodão pelo resíduo de feijão. Os dados das variáveis estudadas foram submetidos às análises de variância e de regressão, adotando-se o nível de significância de 5%. A escolha do modelo foi baseada na significância dos parâmetros de regressão, testada pelo teste t (P<0,05), e nos valores dos coeficientes de determinação. Os níveis de inclusão de resíduo feijão na dieta dos ovinos influenciaram (P<0,05) de maneira linear decrescente os valores de consumos de matéria seca, proteína bruta, matéria orgânica, extrato etéreo e fibra em detergente neutro indigestível expressos em g animal-1 dia-1, percentagem do peso corporal (% PC) e peso metabólico (PC 0,75). Porém foi observado que a inclusão dos diferentes níveis de inclusão do resíduo de feijão não alterou (P>0,05) o consumo de fibra em detergente neutro, carboidratos não fibrosos e nutrientes digestíveis totais dos ovinos confinados. Observou-se que para cada 1,0% da inclusão do resíduo de feijão na dieta de ovinos ocorreu uma redução no consumo de MS de 4,93; 0,01 e 0,20 expressos em g animal-1 dia-1, % PC e PC0,75, respectivamente. A cada 1,0% de inclusão do resíduo de feijão foi observado a redução de 2,73% no consumo de fibra em detergenteneutro indigestível dos ovinos confinados. Os ovinos apresentaram um aumentou linear (P<0,05) no consumo de água com a inclusão dos diferentes níveis do resíduo de feijão nas dietas experimentais.[...](AU)
