Graduate Theses, Dissertations, and Problem Reports (ETD)

Experiments were conducted to investigate the effects of exogenous enzymes in poultry diets. In Chapter 4, a study was conducted to determine the effects of a corn-expressed recombinant carbohydrase (AC1) on broiler performance and digesta viscosity in high non-starch polysaccharide (NSP) diets through 21 days of age. One day-old Hubbard × Cobb 500 chicks were assigned to 6 dietary treatments. Each treatment consisted of 12 replicate pens of 10 birds. The positive control diet (PC) was a corn and soybean meal formulation. The negative control diet (NC) included 10% wheat and 10% corn distiller’s dried grains with solubles (DDGS). The …
