摘要
Sawdust and wood shavings are the major industrial waste from wood and its related industries. Steam-explosion treatment enhances the utilizable fiber fraction in pinewood particles. This study investigated the effects of adding up to 2% of steam-exploded pine particles (SPPs) in diets on the growth performance and cecal microbiome of broilers. On the 8th day of age, 216 Ross 308 broilers were allocated to three treatments of 72 broilers/group, with 12 replicates of 6 broilers each, to receive 0%, 1%, and 2% SPPs in their diets. The experimental period was from the 8th to 28th day of age. The parameters recorded included growth performance, relative organ weight (duodenum, jejunum, ileum, liver, and spleen), absolute organ length (duodenum, jejunum, ileum, and cecum), blood biochemicals (glucose, total protein, triglyceride, and cholesterol), and microbial analysis from cecum samples. Growth performance parameters, such as the average daily gain, average feed intake, feed conversion ratio, organ weight, length, and blood biochemical parameters, were not influenced by dietary supplementation of SPP. The abundance of fibrolytic bacterial genera, such as Mediterraneibacter and Anaerobutyricum, was increased in 2% SPP-supplemented chickens. An unknown bacterial genus was also enhanced in 2% SPP-supplemented diets related to the family of fiber-degrading bacteria and needs further investigation. In conclusion, 2% SPP can be supplemented in chicken diets as a source of fiber from wood industry-related waste without having any harmful effects on broiler chickens.
