Probiotics are also quite widely used and may have a niche when there is a particular need to avoid medicinal additives. However, there are doubts about the cons...

Dietary Inclusion of Thyme Essential Oil Alleviative Effects of Heat Stress on Growth Performance and Immune System of Broiler Chicks

This study was conducted to evaluate the effects of dietary inclusion of thyme essential oil (TEO) on growth performance and immune responses of broiler chicks subjected to heat stress (HS). Broilers were divided into five groups; group 1) chicks fed with basal diet and reared under thermoneutral condition; group 2) chicks fed with basal diet and subjected to HS condition; and groups 3, 4 and 5...

effects of dietary antibiotic, probiotic, prebiotic and organic acid as growth promoters on growth performances and ileal digestibility of nutrients in commercial ross broilers

this experiment was conducted in order to determine the effects of different dietary growth promoters on growth performance and nutrient digestibility in male broiler chickens. a total of 360 male broiler chicks (day-old ross 308 strain) were distributed into a completely randomized design (crd) having 6 dietary treatments with four replicates and 15 birds in each replicate. experimental treatm...
