Local Design system for broiler breeder raring and comparing it with other conventional raring systems in some of blood Performance
AbstractThis study were conducted in poultry farms of Animal Resource Department in College of Agriculture -University of Anbar from 19/1/2013-15/7/2013. ( 320) female have been used in this study and (45) male from broiler breeder ROSS 308 with age of 27 weeks and it has been finished when they AST to ages of 50 weeks (168 days), Five treatments with three replicates of each treatment were distributed in the halls. Two density for each treatment The first treatment (T1) Ground breeding system with low density each replicate consisted of 18 females and 2 males, The second treatment (T2) Ground breeding system with high density, each replicate consisted of 27 females and 3 males, The third treatment (T3) Collective local breeding system with low density each replicate consisted of 18 females and 2 males, The fourth treatment (T4) collective local breeding system with high density, each replicate consisted of 27 females and 3 males and The fifth treatment (T5) conventional cages breeding system each replicate consisted of 6 cages and each cage has 2 females, 15 males were devoted for artificial insemination. Collective local breeding system with low density has recorded significant increase in total protein concentration, cholesterol level in male blood plasma while stress hormones, tri glycerides, low and high density lipoproteins, the ratio of varied cells to lymph cells, packed cell volume (PCV) and hemoglobin ratio stayed at the level that achieve standard welfare for males and females, Conventional cages breeding system has recoded significant increase in H/L ratio, level of tri glycerides, low and high density lipoproteins and, level of glucose in blood, Ground breeding system with low density has recorded accepted results and effective in some performance of production however it was not superior in the other treatments which gave different values from the other systems.
