SUMMARYDietary fibre has traditionally been considered an energy-diluting component of laying hen diets. With low energetic values, and sometimes negative impacts on digesta viscosity gut function, formulations have often aimed to minimise crude contents. Increasing contents can mean that the level fat required meet nutritional standards must be increased account for decrease in energy, with co...

In a growth trial with pigs, the effect of the inclusion of 150 and 300 g of Lupinus albus seeds/kg of feed in the diet was investigated. Parameters studied were: growth, feed utilization, digestibility of nutrients, slaughter and carcass characteristics. Spray dried whole egg powder, a speci®c inhibitor of lectins in L. albus seeds was also added (50 g/kg of feed), with the aim of verifying wh...

Five multiparious Holstein cows, arranged in a 5 5 Latin square design, were fed a control diet (no supplemental fat) and diets containing 5% of the following fat supplements: ̄aked tallow with a low iodine value of 14.4 (FTL), prilled tallow with a low iodine value of 14.5 (PTL), prilled tallow with a medium iodine value of 25.8 (PTM) and fancy bleachable tallow with a high iodine value of 62 ...

The ability of the growing kitten to digest protein, fat, carbohydrate, dry-matter and energy were assessed. Kittens were divided into two groups; one group was fed a wet diet, the other a dry diet. Both groups were allowed ad libitum access to food. Apparent digestibility of the two diets, and kitten bodyweights were measured over a 24-week period. There were no significant differences in mean...

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 ...

AIM To study the effect of dietary supplementation of lecithin and carnitine on growth performance and nutrient digestibility in pigs fed high-fat diet. MATERIALS AND METHODS A total of 30 weaned female large white Yorkshire piglets of 2 months of age were selected and randomly divided into three groups allotted to three dietary treatments, T1 - Control ration as per the National Research Cou...

A 21to 42-day feeding study was conducted in Ross male broilers to evaluate the use of dried bakery product (DBP) and the influence of adding fat at different points in the manufacturing process. Six dietary treatments were formulated using a factorial arrangement (3×2 design) with three levels of fat in the mixer (high: 4.8%, medium: 3.8% and low: 2.8%) with or without DBP (0 and 7%). Addition...

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...
