Two trials were conducted to study the effect of inclusion of hull-less barley and exogenous enzyme to broiler diet on the growth performance, apparent metabolisable energy (AME) and Nutrient digestibility of broiler chickens. The experiments were 3×4 factorial arrangements with three levels of enzyme (0, 300 and 600 g/ton) and four levels of hull-less barley inclusion (0, 10, 20 and 30%) in di...

The effect of feeding 0, 4, 8 and 16% rapeseed oil from 12-42 days of age was studied in broiler chickens on performance, digestibility of nutrients, and development of gastrointestinal tract, protein and energy metabolism. Thirty six female chickens (Ross 208) with initial body weight average 246 g were allocated to the four groups and kept pair-wise in metabolism cages. The chickens were fed ...

Some enzyme supplement products claim benefits for healthy dogs to compensate for alleged suboptimal production of endogenous enzymes and the loss of enzymes in commercial pet foods secondary to processing. The objective of the current study was to determine macronutrient and energy digestibility by healthy adult dogs fed a commercial maintenance diet with or without supplementation with plant-...

Two studies were conducted to evaluate the effects of sorghum wet distillers grains (SWDGS) in finishing diets on steer performance, carcass characteristics, and nutrient digestibility. In Exp. 1, 240 steers (initial BW = 379 ± 1 kg) were fed steam-flaked corn–based diets with or without 25% SWDGS and 7.5, 10.0, or 12.5% alfalfa hay. There were no effects of alfalfa hay concentration on BW, DMI...

The influences of pelleting and 13-glucanase supplementation on the digestibility of dietary components in a barley-based diet were investigated in pigs fitted with cannulas in the terminal ileum. The diet contained 49.0% starch, 18.9% crude protein and 14.8% dietary fiber, with arabinoxylans (4.9%), mixed-linked ~-glucans (3.4%) and cellulose (3.3%) as the main fiber components. Pelleting incr...

This study evaluated the effects of live yeast and yeast cell-wall mannan-oligosaccharide supplementation on performance and nutrient digestibility during early lactation in cows fed a diet based on a mixture of corn silage and alfalfa hay as forage sources. Eight multiparous Holstein dairy cows (average days in milk, 27±6) were used in a replicated 4×4 Latin square design. Diets contained 45% ...

Research has shown that newly hatched birds may be deficient in key digestive enzymes and that the immaturity of the digestive system may result in poor utilization of dietary nutrients. It has also been demonstrated that nutrient digestion rather than the ability to absorb nutrients seems to be the primary limiting factor. Therefore, dietary supplementation of enzymes not produced in sufficien...

Approximately 25 to 40% of the DM in premium dog diets is animal by-product. However, limited information is available regarding the composition and digestibility of these by-products, especially small intestinal digestibility. The effects of raw and rendered animal by-products incorporated into dog diets on nutrient digestion at the ileum and in the total tract were studied in this experiment....

Several experiments were conducted to evaluate the variation in nutrient content and digestibility among different commercial samples of DDGS, the effects of different processing methods and feed additives on the bioavailability of P in DDGS and the effect of new processing technologies on the nutritional value of DDGS for poultry. The nutrient composition varied substantially among DDGS sample...
