Mentha piperita as a promising feed additive used to protect liver, bone, and meat of Japanese quail against aflatoxin B.

The present study was conducted to evaluate aflatoxin B (AFB) detoxification effects of some medicinal plants under both in vitro and in vivo. The in vitro experiment was performed with 25 treatments in 5 replications. The samples of medicinal plants were incubated with AFB for 72 h, and the toxin residual in the supernatant was determined.

Effects of early growth rate and fat soluble vitamins on glucose tolerance, feed transit time, certain liver and pancreas-related parameters, and their share in intra-flock variation in performance indices in broiler chicken.

Three hundred fifty 18-day-old Ross 308 male chicks were used to examine the effects of early growth rate (x̄-3SD, x̄-2SD, x̄-SD, x̄, x̄+SD, x̄+2SD and x̄+3SD) and a fat soluble vitamin (FSV) cocktail on glucose tolerance, whole tract feed transit time (FFT), certain liver, and pancreas related traits as well as their share in intra-flock variance of body weight (BW) at d 42 and feed intake (FI) and feed conversion ratio (FCR) in d 21 to 42 of age. Birds with a greater initial BW (21 d) showed greater FI during d 21 to 42 of age and gained a higher final BW at d 42 of age. The broilers injected with a FSV cocktail consumed more feed with an improved FCR and achieved a noticeable greater BW at d 42 of age compared with the untreated birds (P < 0.

Independent and combined effects of Satureja khuzistanica essential oils and dietary acetic acid on fatty acid profile in thigh meat in male broiler chicken.

A 2 × 6 factorial experiment was conducted to evaluate the effect of Satureja khuzistanica essential oils (SkEO; 0, 200, 300, 400, 500, and 600 mg/bird/day) administered via oral gavage and dietary acetic acid (AA; 0 and 20 g/1 kg) on fatty acids (FA) composition in thigh meat of Ross 308 broiler chickens at days 34, 38, and 42 of age. Dietary AA reduced DWG, DFI, and European economic efficiency index, and increased FCR compared with the nonacidified diet. In day 34 of age, saturated FA (SFA) percentage reduced and polyunsaturated FA (PUFA), n-3, and n-6 percentages increased in the birds that received 400 mg SkEO.
