2. Performance Of Broilers, Under Different Systems Of Brooding And Rearing Associated With Transfer

by Aslam Athar, M | Ehtisham Pervaiz | Javaid Ahmed | Muhammed Nawaz Asghar.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 1986Dissertation note: They study was conducted on Hubbard :hicks at the Poultry Experiment Station, College of Veterinary Sciences, Lahore. The main objective of this study was to find ways and means of efficient broiler raising by using different managemental systems like floor rearing, cage rearing, transferring chicks from floor to cages and from cages to floor at different stages of rearing. Six experimental treatments were investigated, involving 144 broiler chicks. Initially 72 chicks (treatment A) were reared in cages and 72 chicks (treatment B) on floor upto 14' days of age. On 15th day 24 birds were transferred from group A to floor (treatment C) and a similar number was shifted from group B to cages (treatment 0). on 29th day, 24 birds were again shifted to floor (treatment E) from group A. In the same way 24 birds were transferred to cages from group B(Treatment F). The experiment continued upto 8 weeks of age. Responses measured were body weight, feed intake, FCR, Performance Index, Dressing Percentage, Breast Blisters, Mortality and Abnormalities. The body weights at the end of 8th week were 1908,1976, 1869, 2043, 1896 and 2057g; The average feed intake was 4428, 4394, 4460, 4423, 4450 and 4521 g; the FOR was 2.318, 2.230, 2.387, 2.167, 2.350 and 2.199; The performance index was 82.312,88.810, 78.299, 94.4/4l,80.804 and 93.658; and dressing percentage was 68.89, 67.14, 67.78, 69.39, 67.75 and 68.33 for the treatment A, B, C, D, E and F respectively. The results showed that the overall performance of caged broilers in treatments A, D, and F was comparatively better than the treatments of floor (B, C and E). The birds that were transferred to cages (treatment D&F) gave feed conversion ratio which was significantly. (P>0.01) better than all the other groups. The caged birds gained more weight, consumed less feed, gave better FCR and produced more meat per sq. m. than the competitive groups on the floor. Among the birds reared on floor, the chicks of treatment B showed consistently better growth throughout the experiment. The figures for breast blisters and abnormalities were very similar in all treatments. The good performance of caged birds could be attributed to the better utilization of feed due to very limited movements of birds in cages.
