The objective of this study was to assess the effect of substituting corn with soybean hulls on the ingestive behavior and nitrogen balance of Santa Ines lambs. A total of 25 lambs with an initial body weight of 20±2 kg at approximately six months of age, sheltered individually in stalls (1.10 m×1.0 m), considering an entirely casual experimental delineation. Soybean hulls were substituted for ...

This experiment aimed to describe the effects of Oregano extract (OE) inclusion into the concentrate fed to dairy heifers on physiological parameters, feeding behavior, intake, and performance. Thirty-two Holstein heifers were randomly distributed into four treatments: C = control, without addition of OE; OE2.5 = 2.5 g; OE5.0 = 5.0 g and OE7.5 = 7.5 g of Oregano extract per heifer/day. Feeding ...

Southern muriquis (Brachyteles arachnoides) inhabit evergreen and semideciduous forest fragments in southeastern Brazil. Contrary to the broadleaf evergreen forests, the seasonal mesophytic forests experience a relatively severe dry season, which aff ects the muriquis’ diet. Th rough behavioral sampling of feeding activity, I determined the diet of a group of muriquis in a semideciduous forest ...

The Amazonian cichlid peacock bass (Cichla sp.) is a highly marketable food and sport fish, therefore a suitable species for aquaculture. However, because of its piscivorous feeding preferences, the species does not accept dry feeds voluntarily, turning its intensive culture difficult and costly. This study aimed to wean fingerling peacock bass from inert moist food to dry diets. In a first exp...

The essential role of taurine in the diet of the cat has been well documented and a deficiency of this nutrient is known to be responsible for a number of clinical conditions. At present, the National Research Council (1986) recommendation for the minimum dietary requirement of the kitten is 400 mg/kg dry matter and for a pregnant cat is 500 mg/kg dry matter. However, these minima were establis...

the objective of this study was to evaluate whether the adverse effects of high dietary rice bran (rb) inclusion levels on the feed intake, performance, bone status and nitrogen (n) retention of broilers could be mitigated by wet feeding. giving a completely randomized design experiment in 2 × 2 factorial arrangement, seventy two broiler chickens, managed in 24 floor pens received one of the tw...

The eating behaviour of horses offered wheat distiller grains at varying levels in the concentrate was examined in two experiments. The objective of the study was to evaluate the effect of rate of inclusion and presentation (dry vs. soaked) of wheat distiller’s grains, and the responses in behaviour and processes of intake. In both experiments, the rates of inclusion were 1.00:0, 0.75:0.25, 0.5...

Processing cereal grains generally increases starch digestion and improves feed efficiency and/or gain. However, the supply and cost effectiveness of using either wet corn gluten feed (WCGF) or wet distillers grains plus solubles (WDGS) is likely to increase in the future. Therefore, understanding how grain processing interacts with these byproducts will be critical for feedlots. Feeding wet by...

Despite the fact that many plant-feeding insects are pests, little effort has been made to identify key evolutionary trait transitions that allow taxa to acquire or lose pest status. A large proportion of species in the genus Callosobruchus are economically important pests of stored, dry postharvest beans of the tribe Phaseoleae. However, the evolution of this feeding habit is poorly understood...
