Gross morphometrical observation on bursa of Fabricius in developing guinea fowls (keets)

Gross biometrical observations were made on developing bursa of Fabricius of 75 keets at 7 day interval from day 1 to day 63 of age. The bursa weighed 0.034, 0.404 and 0.870 g at 1, 35 and 63 day of development, respectively. The percent increment in the weight of bursa was 52.94, 71.91 and 5.07 during 1 to 7, 29 to 35 and 57 to 63 day of age respectively. The bursa constituted 0.14, 0.19, and 0.15 per cent of the body weight on 1^st, 35^th and 63^rd day of age, respectively. The diameter of bursa at day 1, 35^th and 63^rd day was 0.38, 1.35 and 1.73 cm respectively. The percent increment in bursal diameter was 18.42, 70.88 and 1.76 during 1. to 7, 29 to 35 and 57 to 63 day of development, respectively.
