Impact of feeding modified soy protein concentrate in the starter phase on growth performance and gastrointestinal responses in broiler chickens through to day 42 of age

Growth performance and physiological responses of feeding modified soy protein concentrate (MSPC, 72% CP) in the starter phase were investigated. A total of 1,216 d old male Ross x Ross 708 broiler chicks were placed in 32 floor pens based on BW, fed one of 4 (n = 8) corn-soybean meal-based diets fo...

description Growth performance and physiological responses of feeding modified soy protein concentrate (MSPC, 72% CP) in the starter phase were investigated. A total of 1,216 d old male Ross x Ross 708 broiler chicks were placed in 32 floor pens based on BW, fed one of 4 (n = 8) corn-soybean meal-based diets formulated with 0, 7.7, 10.0 or 12.5% MSPC for 10 d and transitioned to common diets to d 42. Feed intake, BW, and mortality were measured. Samples of birds were bled on d 10 for plasma uric acid (PUA) and subsequently necropsied for organs weight and samples of pancreatic tissues for enzyme activity, jejunal tissues for enzyme activity and histomorphology and ceca digesta for microbial activity. Litter moisture was determined on d 36 and 42 and sample of birds were necropsied on d 42 for breast yield and ceca digesta sample for microbial activity. Feeding MSPC linearly (P < 0.001) increased starter growth performance. Overall (d 0–42), MSPC linearly (P = 0.05)improved FCR; The FCR was 1.566, 1.535, 1.488 and 1.527 for 0.0, 7.7, 10.0, and 12.5% MSPC, respectively. Feeding MSPC linearly (P ≤ 0.04) increased breast yield and decreased small intestine length, gizzard digesta pH, and PUA. Breast yield was 230, 238, 246, and 252 g/kg BW for 0.0, 7.7, 10.0, and 12.5% MSPC, respectively. Pancreatic and jejunal chymotrypsin and trypsin activities and histomorphology were not (P > 0.10) influenced by the diets. On d 10, MSPC linearly (P < 0.05) reduced ceca digesta abundance of Ruminococcaceae, E. Coli, and Clostridium but increased abundance of Bifidobacterium and the ratio of Lactobacilli and E. Coli. Birds fed MSPC showed linear (P = 0.01) increase in abundance of Bifidobacterium on d 42. Feeding MSPC linearly increased ceca digesta acetic (P = 0.01) and reduced propionic (P = 0.048), and iso butyric (P = 0.003) in 10 d old broiler chicken. In conclusion, up to 12.5% MSPC inclusion in the starter phase increased growth performance through to d 42 linked to enhanced gut health through reduction of enteric pathogens.
