Feeding broiler chicks with Schizosaccharomyces pombe-expressed phytase-containing diet improves growth performance, phosphorus digestibility, toe ash, and footpad lesions
OBJECTIVE: The objective of this study was to evaluate the effects of dietary supplementation of Schizosaccharomyces pombe (S. pombe) -expressed phytase on growth performance, apparent ileal digestibility, organ indexes, meat quality, toe ash, and footpad lesions score in broiler chicks. METHODS: A...

description | OBJECTIVE: The objective of this study was to evaluate the effects of dietary supplementation of Schizosaccharomyces pombe (S. pombe) -expressed phytase on growth performance, apparent ileal digestibility, organ indexes, meat quality, toe ash, and footpad lesions score in broiler chicks. METHODS: A total of 390 one-day-old broiler chicks were randomly assigned to 5 groups based on the initial body weight (42.15±0.17 g), there were 6 replicate cages per treatment and 13 birds (mixed sex) per cage. The experimental period was 45 days, including 4 periods (starter, days 1 to 10; grower, days 11 to 24; finisher 1, days 25 to 38; finisher 2, days 39 to 45). Dietary treatments were based on a corn-soybean meal-basal diet and supplemented with 500, 750, 1,000, and 1,500 FTU/kg S. pombe-expressed phytase. One phytase unit (FTU) was defined as the amount of enzyme that catalyzes the release of one micromole phosphate from phytate per minute at 37°C and pH 5.5. RESULTS: The inclusion of increasing levels of phytase in the diet linearly increased the body weight gain during days 1 to 10 (p = 0.001), 25 to 38 (p = 0.016), 39 to 45 (p = 0.018), and 1 to 45 (p = 0.004), feed intake during days 25 to 38 (p = 0.032), feed conversion ratio during days 1 to 10 (p = 0.001), 39 to 45 (p = 0.038), and 1 to 45 (p = 0.012), carcass weight (p = 0.035), toe ash (p<0.001), and apparent ileal phosphorus digestibility (p = 0.049). However, the footpad lesions score (p = 0.040) decreased linearly with the increase in phytase levels in the diet. CONCLUSION: Dietary supplementation of S. pombe-expressed phytase was beneficial to the growth performance, toe ash, apparent ileal phosphorus digestibility, and footpad lesions of broiler chicks in a dose-dependent manner. |
