| description | This study was conducted to assess the effects of the dietary supplementation of
riboflavin (as a bile salt hydrolase [BSH] inhibitor) and Bacillus
subtilis on growth performance and woody breast of male broilers
challenged with Eimeria spp. Intestinal bacteria, including
supplemented probiotics, can produce BSH enzymes that deconjugate conjugated
bile salts and reduce fat digestion. A 3 × 2 × 2 (riboflavin
× Bacillus subtilis × Eimeria
spp. challenge) factorial arrangement of treatments in randomized complete block
design was used. On d 14, birds were gavaged with 20× doses of commercial
cocci vaccine (CoccivacR-B52, Merck Animal Health, Omaha, NE).
Dietary treatment of riboflavin and B. subtilis did not affect
body weight (BW), body weight gain (BWG), and feed conversion (FCR) d 0 to 14
and overall d 0 to 41. Eimeria spp challenge reduced BWG, feed
intake (FI), and increased FCR between d 14 to 28, but increased BWG and lowered
FCR between d 28 to 35. There were no effects of the Eimeria
spp. challenge on the overall d 0 to 41 FCR and FI, but BWG was reduced.
Eimeria spp. challenge increased the abdominal fat pad
weight and slight woody breast incidences on processed birds on d 42. Dietary
inclusion of B. subtilis and riboflavin at tested levels did
not help birds to mitigate the negative impact of Eimeria spp.
challenge to enhance the growth performance. |
