The objective of the present study was to determine effect of pomegranate seed oil (PSO) and linseed oil (LO) on haematological parameters, serum lipid profile and liver enzymes as well as fatty acids profile of adipose tissue in broilers. Broilers (n = 400) were fed on diets containing graded PSO levels (0.0%, 0.5%, 1.0%, 1.5%) with or without 2% LO. After 6 weeks of feeding, 6 male broilers from each group were slaughtered and abdominal fat, liver and blood samples were collected. Mixtures of pomegranate seed oil (0.5%, 1%) with linseed oil increased white blood cell level in broilers. Total cholesterol was elevated after LO supplementation whereas administration of PSO (1.5%) significantly decreased this parameter. PSO administration caused c9,t11 conjugated linoleic acid (CLA) concentration-dependent deposition in adipose tissue. By LO addition α-linolenic acid (ALA) content was enhanced, decreasing the n-6/n-3 ratio. PSO and ALA also affected oleic acid proportion in adipose tissue. Neither pomegranate seed oil nor linseed oil had any effect on liver parameters. Pomegranate seed oil had no negative effects on broiler health status and can be considered as a functional poultry meat component.
本研究的目的是确定石榴籽油（PSO）和亚麻籽油（LO）对肉鸡血液学参数、血清脂质谱、肝酶以及脂肪组织脂肪酸谱的影响。将400只肉鸡饲喂含不同梯度PSO水平（0.0%、0.5%、1.0%、1.5%）且添加或不添加2% LO的日粮。饲喂6周后，每组宰杀6只雄性肉鸡，并采集腹部脂肪、肝脏和血液样本。石榴籽油（0.5%、1%）与亚麻籽油的混合物可提高肉鸡白细胞水平。添加LO后总胆固醇升高，而给予PSO（1.5%）可显著降低该参数。给予PSO导致共轭亚油酸（CLA）在脂肪组织中呈浓度依赖性沉积。添加LO可提高α-亚麻酸（ALA）含量，降低n-6/n-3比值。PSO和ALA也会影响脂肪组织中油酸比例。石榴籽油和亚麻籽油对肝脏参数均无影响。石榴籽油对肉鸡健康状况无负面影响，可被视为功能性禽肉成分。
