Effect of live Eimeria vaccination or salinomycin on growth and immune status in broiler chickens receiving in-feed inclusion of gelatin and vitamin E

Impacts of phytase and coccidial vaccine on growth performance, nutrient digestibility, bone development, and intestinal gene expression of broilers fed a nutrient reduced diet

“…A lack of effect on the inflammatory cytokines could be due to the birds being still in immune priming phase. On the contrary, previous studies reported that coccidial vaccine increased proinflammatory cytokines expression ( Shaw et al, 2011 ; Lee et al, 2013 ; Tan et al, 2014 ; Orso et al, 2022 ). The difference may be due to doses or type of vaccine (nonattenuated vs. attenuated), thus triggering a different immune response in broilers.…”

Effect of microbial muramidase supplementation in diets formulated with different fiber profiles for broiler chickens raised under various coccidiosis management programs

“…Supplementation of Salinomycin also provided better BWG and FCR compared to the coccidiosis vaccinated birds. The response of the coccidiosis vaccine was not unexpected since it is known that coccidiosis vaccine may lead to worse performance of broilers when compared to Salinomycin ( Orso et al, 2022 ), due to the lesions caused by the coccidia during its cycling. Orso et al (2022) showed a reduction of 147 g in coccidiosis vaccinated birds vs. Salinomycin, and 4.5 points worse FCR.…”

Moreover, fermentable fiber-based diet and coccidiosis vaccine reduced total carotenoid concentration in the blood, highlighting that these factors interfere with nutrient absorption and consequently are detrimental to growth performance of the birds.…”

Botanicals: A promising approach for controlling cecal coccidiosis in poultry

“…Vitamins and minerals act as antioxidants and immune stimulators, helping control cecal coccidiosis ( 275 – 277 ). Vitamins and minerals, i.e., vitamin E, selenium ( 278 , 279 ), vitamin K ( 280 ), vitamin A, vitamin D ( 281 , 282 ), etc., have been shown to be effective in reducing the signs and symptoms of coccidiosis in various multiple experiments.…”
