STUDIES ON SOME IMMUNE AND PRODUCTIVE PERFORMANCE OF SOME LOCAL AND ADAPTED STRAINS USING MODERN SNAPS TECHNIQUES

Abstract

ABSTRACT This experiment was designed to evaluating some productive traits and immune traits of Baladi chickens under heat stress condition and description of Baladi chickens genetically by using modern techniques. Main results could be summarized as follows: • Growth characteristics (body weight and body measurement) reflect that males of baladi chickens were significantly heavier than their counterparts at different ages. Also, the heat treatment group induced a significant decrease in body weight compared with the control treatment group for both sexes in parents stock.so, in offspring stock. And, heat treatment induced a significant decrease compared with control group in body weight trait. Also, heat treatment induced a significant decrease compared with control group in all body measurements(shank length, tibia length ,body depth, keel length, comb length and wattle length) • Feed consumption and feed conversion ratio of baladi chickens recorded at 8-12 weeks of age. The present result showed that the Baladi chickens that was exposed to heat stress significantly consumed less feed from 8 to 12 days of age compared to the control treatment group. • Phenotypic, the results showed that in the parent stock, at one day of age, orange color (light brown) was the dominant color among the colors within the stock 32% of the all stock, and at the age of 4 weeks, the orange color also appeared to be the dominant color among the colors by 35%. But, the results showed that in offsprings stock, at one day of age, orange color (light brown) was the dominant color among the colors within the stock 40% of the all stock, and at the age of 4 weeks, the orange color also appeared to be the dominant color among the colors by 65%.
