Interaction between live vaccines for coccidiosis and phytogenic compounds in the diet of broilers.

This study aimed to determine whether live vaccines alone or associated with phytogenic compounds supplied via feed could improve performance, intestinal health, serum biochemistry, and coccidiostatic action in broilers up to 42 days of age, challenged with Eimeria spp., compared with a traditional anticoccidial program. We used 800 birds divided into five treatments of eight repetitions each (n = 20): NC - Negative control (absence of additives in the feed and without coccidian challenge); PC - Positive control (absence of additives and with coccidian challenge at 21 days); AAP - Anticoccidial additives program, including salinomycin and nicarbazine, with coccidian challenge at 21 days of life; VAC - Vaccination on day 1 of life (Hipracox HIPRA®) against coccidiosis and subsequent coccidian challenge at 21 days; VAC + BPC - Vaccination (day 1 of life), the addition of 200 ppm of blend phytogenic compound (BPC) based on carvacrol and cinnamaldehyde to the diet, with coccidian challenge at 21 days of life.

Microencapsulated carvacrol and cinnamaldehyde replace growth-promoting antibiotics: Effect on performance and meat quality in broiler chickens.

The aim was to evaluate the use of mixture of microencapsulated carvacrol and cinnamaldehyde as a replacement for growth-promoting antibiotics in broiler diets on performance, intestinal quality, organ development, carcass yields and cuts, and meat quality. In the trial were used 600 male chicks, allocated in a completely randomized design, with five treatments and eight replicates of 15 birds, reared up to 41 days of age. The treatments were: Negative Control (NC), Positive Control (PC) 30 mg/kg of virginiamycin, NC+100 mg/kg of essential oils, NC+200 mg/kg of essential oils and NC+400 mg/kg of essential oils.

Phytogenic blend protective effects against microbes but affects health and production in broilers.

The aim of this study was to determine whether addition of a phytogenic blend in the feed of broilers to replace conventional antimicrobials as a performance enhancer would improve or maintain productive efficiency. The phytogenic blend was based on curcuminoids, cinnamaldehyde and glycerol monolaurate. We used 480 birds divided into three groups with eight repetitions per group and 20 birds per repetition.
