Abstract
The present study was conducted to investigate the effects of borage extract (BE) on growth performance and the immune system of broilers at high-stocking-density. A total of 330 male Ross 308 broilers were distributed in a completely randomized design with six experimental treatments each with three replications. Treatments were T1: 10 broilers/m2 (positive control group), T2: 20 broilers/m2 (negative control group), T3: 20 broilers/m2 + 150 mg/l of borage extract (BE), T4: 20 broilers/m2 + 300 mg/l of BE, T5: 20 broilers/m2 + 450 mg/l of BE, and T6: 20 broilers/m2 + 600 mg/l of BE. Weight gain, feed intake, and feed conversion ratio (FCR) were measured weekly and immune responce were examined twice. The use of BE could improve weight gain, feed intake, and FCR in broilers reared at a high-stocking-density. BE treatment improved the immune response of broilers. According to the results, the use of BE at 600 mg/l is useful in reducing the effects of density stress. Therefore, BE can be used as a nutritional strategy to improve the bird performance in stressful conditions.
期刊介绍:
Journal of Applied Animal Welfare Science (JAAWS) publishes articles on methods of experimentation, husbandry, and care that demonstrably enhance the welfare of nonhuman animals in various settings. For administrative purposes, manuscripts are categorized into the following four content areas: welfare issues arising in laboratory, farm, companion animal, and wildlife/zoo settings. Manuscripts of up to 7,000 words are accepted that present new empirical data or a reevaluation of available data, conceptual or theoretical analysis, or demonstrations relating to some issue of animal welfare science. JAAWS also publishes brief research reports of up to 3,500 words that consist of (1) pilot studies, (2) descriptions of innovative practices, (3) studies of interest to a particular region, or (4) studies done by scholars who are new to the field or new to academic publishing. In addition, JAAWS publishes book reviews and literature reviews by invitation only.
