Unhydrolyzed Vegetable Sucrose Polyester in Broiler Diets

Sucrose polyester in human volunteers.

The recent publication by Kelly et al. (1998) of their study on sucrose polyesters (SPE) raised concerns about the possible gastrointestinal (GI) and nutritional effects of olestra. These concerns were echoed in the popular press (‘Doubts raised over anti-obesity fat substitute’. The Times, 11 August 1998.). Olestra’s potential to cause GI and nutritional effects has been carefully reviewed by ...

Broiler Litter in Ruminant Diets -implications

Use of byproducts in ruminant diets can decrease production costs and increase total production. Chemical and physical characteristics of byproduct feedstuffs and animal nutrient requirements determine most appropriate means of use. Broiler litter is high in ruminally degraded crude protein and moderate to low in available energy concentration; therefore, most efficient use is as a crude protei...

Sources of Betaine as Methyl Group Donors in Broiler Diets

Betaine is donor of methyl groups and can partially replace methionine in diets for this purpose. The objective of this study was to evaluate three sources of betaine in partial substitution of methionine supplement in broiler diets. The Cobb-500 broiler chickens were allocated in a completely randomized experimental design with 5 treatments and 7 replicates of 49 birds each. The positive contr...

Nutritional Feasibility of L-Valine Inclusion in Commercial Broiler Diets

Introduction The poultry industry has recently dealt with fluctuating spikes in the price of various feed ingredients. When the cost of protein-rich feed ingredients goes up, the reduction of dietary crude protein via the use of commercially available amino acids becomes an effective formulation strategy that can reduce diet costs, maintain broiler performance and not interfere with feed millin...
