Apple peel waste as a natural antioxidant for heat-stressed broiler chickens

Abstract

This study was conducted to evaluate the effects of processed apple peel waste (APW), alone or in combination with an enzyme, as a natural antioxidant on broiler chickens under heat stress. A total of 360 unsexed, 28-day-old broilers were assigned to 6 dietary treatments with four replicates (15 broilers per pen). The experiment consisted of a 3 × 2 factorial arrangement with three levels of apple peel waste (0, 50 or 100 g/kg of diet) and two levels of enzyme (0 or 500 mg/kg, ZY Multi(®)). Inclusion of 100-g APW/kg of diet decreased broiler weight gain at 42 days of age. Inclusion of 50 and 100-g APW/kg of diet increased gizzard and small intestine weights. Feeding 50 and 100-g APW/kg increased high-density lipoprotein (HDL) cholesterol and decreased low-density lipoprotein (LDL) cholesterol and malondialdehyde in blood serum at 49 days of age. At 49 days of age, apparent ileal protein digestibility was reduced when 50 and 100-g APW/kg were used in the diet. This study showed that feeding APW up to 50 g/kg from 28 to 49 days of age increased HDL cholesterol and decreased LDL cholesterol in serum and had no adverse effect on broiler performance.

Effect of incremental levels of apple pomace and multi enzyme on performance, immune response, gut development and blood biochemical parameters of broiler chickens

“…As mentioned previously body weight of broilers in different rearing phases affected by DAP and interaction effect of DAP and enzyme supplementation in their diets (P < 0.05). Similar to obtained results, Heidarisafar et al (2016) observed that 50 g/kg apple peel waste caused to similar body weight to control group, and inclusion of 100 g/kg apple peel waste decreased body weight of broilers at 42 days of age. Also, they observed that adding multi enzyme to broiler diet had no effect on body weight of broilers at 42 or 49 days of age, which is disagree with obtained results in recent study.…”

“…Incorporation of fruit by-products with high fiber seemingly affects birds to modify their feed intake and preserve adequate energy consumption. The excessive use of fiber sources may also increase the viscosity of intestinal content and decreases bioavailability of nutrients (Heidarisafar et al 2016).…”

Effects of feeding cassava pulp fermented with Acremonium charticola on growth performance, nutrient digestibility and meat quality of broiler chicks

“…This inference was supported because the administration of probiotic Lactobacillus spp. (Olnood et al, 2015) or processed apple peel waste (as a natural antioxidant) (Heidarisafar et al, 2016) increased the small intestinal weight (jejunum and ileum) of broiler chicks.…”

Effects of high ambient temperature on plasma metabolomic profiles in chicks

“…In fact, the supplementation of poultry feed with antioxidants can attenuate some of the detrimental effects (Heidarisafar et al 2016;Hosseini-Vashan et al 2016;Rafiee et al 2016). Much attention has been focused on combating the effect of oxidative stress induced by heat exposure.…”

“…Much attention has been focused on combating the effect of oxidative stress induced by heat exposure. In fact, the supplementation of poultry feed with antioxidants can attenuate some of the detrimental effects (Heidarisafar et al 2016;Hosseini-Vashan et al 2016;Rafiee et al 2016). However, the precise mechanisms underlying physiological and pathophysiological changes induced by heat exposure remain unknown.…”
