Efeito de diferentes níveis de manganês e fósforo sobre o desempenho e a qualidade da casca dos ovos de poedeiras comerciais

Abstract: RESUMO -O objetivo desta pesquisa foi avaliar o efeito de diferentes níveis de manganês e fósforo (P) sobre o desempenho e a qualidade da casca dos ovos e de determinados constituintes sangüíneos, em 96 galinhas Hy-Line W36, com 60 semanas de idade, distribuídas em 24 lotes com quatro aves cada. O delineamento usado foi o inteiramente ao acaso em arranjo fatorial (3x2), níveis de manganês (70, 140 e 210 ppm) e níveis de fósforo total (0,35 e 0,55%), totalizando seis tratamentos com quatro repetições cada. As r… Show more

“…(2015) in an experiment that was conducted for bio‐efficacy comparison of organic Mn with inorganic Mn (0, 25, 50, 100, and 200 mg/kg) in Hy‐Line Brown laying hens reported that dietary Mn supplementation with organic Mn at 50 mg/kg level had the highest feed efficiency and the lowest feed intake, when the data were extrapolated from the 12‐week feeding trial (55–62 weeks of age). In contrast with the current study and above reports, many studies (Faria et al., 1999; Mabe et al., 2003; Sazzad et al., 1994; Venglovska et al., 2014; Xiao et al., 2015, 2014; Yıldız et al., 2011) reported that egg performance parameters did not exhibit a significant response to Mn dietary supplementation levels and sources ( p > 0.05). Sazzad et al.…”

“…Faria et al. (1999) showed that dietary Mn levels (70, 140, or 210 mg/kg) did not affect the performance of laying hens as did Venglovska et al. (2014), who stated that feeding 120 mg/kg did not affect the performance of 20‐week‐old hen layers.…”
