Location of Chickens Within Rearing Floors of Laying Hens Closed Halls and Its Effect of Productive, Physiological and Qualitative Eggs Characteristics

Abstract

Abstract This study was conducted in (Samarra Poultry Commercial Project), located in Samarra, 130 km north Baghdad, in a closed hall of Turkish origin, containing 53,000 Lumen Brown laying hens, 34 weeks of age, raised in cages, each of which accommodates 10 birds and distributed into five lines, each is mixed with five floors. Very symmetrical, including ten. In order to know the effect of the location of chickens within floors. Breeding in closed halls lines on productive performance, quality traits of eggs and some traits blood physiology: The results showed the following. Significantly decreased egg production in birds bred within the first (ground) floor, and this was accompanied by a significant decrease in egg production. Deterioration in the efficiency of feed conversion.. The location of the chickens within the breeding floors had no significant effect on most of the qualitative characteristics of eggs. The chickens raised on the third floor showed the best parameters of red blood cells, with a stabilization of the case. There were no significant differences in the numbers of white blood cells.
