The objective of this study was to evaluate the chemical characteristics of the forage and ingestive behavior of Nellore heifers fed hydrolyzed sugarcane in different periods of storage. Twenty-four heifers with initial body weight of 119.6±8.1 kg were utilized. The experimental design was completely randomized, in which the treatments were diets with fresh sugarcane and hydrolyzed sugarcane (5 g of lime kg-1 of chopped sugarcane) stored for 24, 48 or 72 hours as the only roughage. The addition of lime to sugarcane associated with its storage up to 72 hours provided an increase of 20% of the potentially degradable cell wall of carbohydrates, from 382.4 to 458.8 g kg-1 of total carbohydrates. The in vitro digestibility of dry matter was altered by the...

Selectivity and feeding behavior of Saanen goats subjected to three nutritional levels R. Bras. Zootec.
Gomes,Helen Fernanda Barros; Souza,Samuel Figueiredo de; Oliveira,Daiana de; Biagioli,Bruno; Teixeira,Izabelle Auxiliadora Molina de Almeida; Resende,Kleber Tomás de.
ABSTRACT This study was conducted to investigate the effect of selective feeding habits on the quality of the ingested diet and the effect of feed restriction on the selectivity and behavior of goats in feedlots. Differences were found only in the amount of feed given to the animals, with a difference in the amount of feed rejected as a function of the nutritional level. Higher levels of orts were measured for those animals that received the ad libitum diet. For the composition of orts, differences were measured only in the ether extract fraction. Animals fed the ad libitum diet increased their intake of ether extract and energy, crude fiber, neutral detergent fiber, and acid detergent fiber. Thus, they had a preference for consuming the fibrous and...

Conceição,Maria Gabriela da; Ferreira,Marcelo de Andrade; Campos,José Maurício de Souza; Silva,Janaina de Lima; Detmann,Edenio; Siqueira,Michelle Christina Bernardo de; Barros,Leonardo José Assis de; Costa,Cleber Thiago Ferreira.
ABSTRACT The effect of replacing wheat bran with spineless cactus (0, 25, 50, 75, and 100%) in sugar cane-based diets on the intake of nutrients, feeding behavior, and rumen digestibility of steers was assessed using digested samples collected from the omasum. Five crossbred steers (1/2 Holstein-Zebu) were fitted with cannulas in the rumen and then assigned to a 5 × 5 Latin square design. Samples of omasal digesta were collected for three days. Rumen was evacuated via the rumen cannula to determine the rumen pool of dry matter (DM), neutral detergent fiber (NDF), indigestible NDF (iNDF), intake (ki), passage (kp) and degradation (NDF) rates, and the passage of iNDF (kpi). Nutrient intake displayed a quadratic effect, with maximum intakes of DM (5.73 kg...

Ingestive behavior and efficacy of male sheep housed in different stocking densities R. Bras. Zootec.
Costa,Roberto Germano; Ribeiro,Neila Lidiany; Nobre,Priscila Torres; Carvalho,Francisco Fernando Ramos de; Medeiros,Ariosvaldo Nunes de; Martins,Fabrício Ehm.
ABSTRACT The objective of this study was to analyze the effect of housing density on ingestive behavior of male Santa Inês sheep housed individually and in double. Forty non-castrated males were used with an average initial weight of 21.33±2.62 kg and an average age of 120 days. The males were housed in two types of covered stalls: double stalls (two males/stall) of 3.0 m2 and individual stalls of 1.50 m2. Animals housed in individual stalls spent more time ruminating and less time eating than those in double stalls. These animals also spent more time in idleness. Sheep idled approximately 11.43 hours/day (47% of the time), which can be explained by the shorter time spent in rumination, considering that the diet used in this experiment had adequate...
