This trial was done to determine broiler live performance to 42 days, under a hot climate in India. 2080 VenCobb 400 broilers were allocated in 4 groups with 26 birds per floor pen and 20 replicates per group: negative control group (NC), positive control group (PC), direct-fed microbial group (DFM) at Log 5 CFU/g of feed and Bacitracine group (BMD) at 500 g/T of feed. The DFM product was composed ...

Over the past decades, genetic improvements have stimulated broiler production resulting in birds weighing ± 3kg in 42 d. To reach this genetic potential, the absorption and digestion of nutrients and according morphological and functional development of the small intestine in the early life must be impeccable. Before hatch, uptake of nutrients by the chicken embryo is limited but rapid inc ...

Abstract Since the ban of using antibiotic growth promoters (AGPs) in livestock in several countries, probiotics have been considered as possible alternative. Spore forming bacteria that belong to Bacillus species are one of those probiotics selected for their ability to resist adverse environmental and nutritional conditions such as, low pH in the stomach and high temperature of the feed manufac ...

Abstract An experimental direct-fed microbial (DFM) was evaluated in a dose- response trial to determine broiler live performance to 42 d with Coccivac® B at placement (d 0), used litter on d 4, and toxin-producing Clostridium perfringens (Cp) challenges on d 17-18 (by oral gavage and via water trough daily). There were 8 dietary treatment groups with 10 replicate pens of 30 chicks each per t ...

Abstract Necrotic enteritis (NE) caused by Clostridium perfringens (CP) is a devasting bacterial disease responsible for economic losses, by increasing mortality because of damage to the broiler small intestine. Since ban of antibiotics use as growth promoters (AGPs) in some markets like in Europe and no antibiotic ever programs (NAE) in U.S., economic losses have become more prevalent. To preven ...
