Broyler Rasyonlarında Prebiyotik ve Organik Asit Kullanımının Yem Tüketimi, Canlı Ağırlık Artışı, Yemden Yararlanma, Performans, Karkas Verimi ve Bazı Kan Parametreleri Üzerine Etkilerinin Belirlenmesi

Abstract

The study will be carried out by dividing 160 Ross 308 broiler chicks into 4 groups and each group to contain 4 subgroups. The groups consumed the basic ration, the control group, the basic ration + Prebiotic (prebiotic 100 mg / kg), the basic ration + Organic acid (3.0 g / kg), the basic ration + Prebiotic (prebiotic 100 mg / kg), + Organic Acid (3 ,0 g/kg) group. The nutrient content of the basic ration will be prepared to include 23% crude protein and 3100 kcal/kg metabolic energy, as in broiler starter feeds (NRC, 1994). The hatched chicks will be brought to Kırıkkale University Veterinary Faculty Poultry Feeding and Care Unit on the same day, and will be divided into groups after their live weights have been weighed. The chicks will be provided with feed and water ad libitum. The work will take 42 days. Weekly live weights and live weight gains will be determined by weighing the live weights again on the 7th, 14th, 21st, 28th, 35th and 42nd days from the start of the study. Again, on the day of the live weight weighing, the remaining feeds in front of them will also be weighed and their weekly feed consumption will be determined. The feed efficiency ratios will be calculated by proportioning the amount of feed consumption obtained with the live weight gain. On the 42nd day, 8 animals from each group were given v. 15 ml of blood will be taken from the jugularis to make blood analysis and the animals will be decapitated. The internal organs of the slaughtered animals will be removed, and the weight of the hot carcass and, one day later, the cold carcass weight will be determined.
