Effects of Micronized Bamboo Powder on Growth Performance, Serum Biochemical Indexes, Cecal Chyme Microflora and Metabolism of Broilers Aged 1-22 Days

Abstract

Necrotic enteritis is common in broilers, which makes negative effects on growth performance. Adding insoluble fiber to diet of broilers has been reported to improve intestinal health and promote growth performance. Bamboo powder is a cheap raw material with rich insoluble fiber. This study aims to explore the effects of feeding micronized bamboo powder (MBP) on growth performance, serum biochemical indexes, intestinal microflora, and metabolism of broilers. A total of 1440 1-day-old ephedra chickens were randomly divided into three groups considering gender and body weight: (1) Group D: feeding with basal diet without antibiotics; (2) Group E: feeding with basal diet supplemented with 5% rice bran (RB); (3) Group F: feeding with basal diet supplemented with 1% MBP. Each group involved 8 replicates, with 60 chickens per replicate. After feeding for 22 days, various indexes were detected. For the growth performance, the weight gain and feed consumption ratio (G: F) of Group F supplemented with MBP is 0.57 ± 0.04, which is significantly higher than that of E group supplemented with RB (0.52 ± 0.01, P < 0.05). For the serum biochemical indexes, the glutathione peroxidase activity in Group F is significantly higher than that of in Group D, while the malondialdehyde content is significantly lower than that of in Group D and Group E (P < 0.05 for all). The fresh cecal chyme is taken for determination. In Group F, the α diversity index Faith_pd is significantly lower in Group F than that of in Group D. The microorganism species in cecal chyme of Group F and Group E are also different. The metabolic pathways of Group F differ from those of Group D and Group E, mainly manifested in fatty acid metabolism, amino acid metabolism and intestinal immune IgA production. Adding 1% MBP to broiler diet can enhance the anti-oxidant capacity, improve chyme microflora, regulate the metabolism pathways responsible for intestinal fatty acids, amino acids, and immunity.

“…In addition, the 5.0% FBP addition diet decreased the F:G compared to the pigs fed the 10% FBP addition diet. This was consistent with the previous study reported by Dai, et al [ 22 ], where the weaned piglets fed diets with 1% micronized bamboo powder addition increased their ADG but decreased their F:G compared with the CON diet. Similarly, another study revealed that 1% micronized bamboo powder could also improve the growth performance of broilers in an antibiotic-free basal diet [ 16 ].…”

Micronized Bamboo Powder Affects the Growth Performance, Intestinal Development, Cecal Chyme Microflora and Metabolic Pathway of Broilers aged 24-45 days

“…Metabolic energy (ME) in the diets of the Group D and F was the same, with according to the assumption that the energy value of MBP was equivalent to that of corn under the condition of appropriate addition. Our previous reports showed that adding 1% of MBP to replace equivalent corn had no negative impact on the growth performance of piglets and young broilers (Dai et al 2021;Dai et al 2022).…”

“…Bamboo powder can be used in the feed of ruminants after fermentation (Okano et al 2009;Oguri et al 2013), while few report has been performed on its feeding value for Monogastric animals. Our previous study revealed that adding 1% of micronized bamboo powder (MBP) to replace equivalent corn can improve the growth performance of weaned piglets, and the improvement effect of super-MBP is higher than that of general-MBP (Dai et al 2021). Meanwhile, MBP is expected to be used as a functional dietary ber raw material for broiler to reduce feed costs and improve breeding e ciency.…”
