Pola Pertumbuhan Ayam Broiler Strain Lohmann Berdasarkan Osteometri Tulang Sayap

The aim of this study was to determine the growth pattern and osteometry of the the Lohmann strain broiler chicken, and the osteometry points, of forelimb bone. The measurement of the wing bone was done in the lenght, width, circumference and weight of the bone using a calipers with an accuracy 0f 0.05 mm. The result showed that the Lohmann strain broiler chicken growth patterns based on forelimb bone osteometry at 7, 21 and 35 days, concluced that there were significant result (p<0.05) to the average length, width (proximal, corpus and distal), circumference (proximal, corpus and distal) and weight on the os scapula, os coracoid and os clavicula and the bone of the free motion constituents consisting of the os humerus, os radius, os ulna, os metacarpal I, os metacarpal II, os metacarpal III, ossa digiti I, ossa digiti II dexter phalang I dan Phalang II, ossa digiti II sinister Phalang I dan PhalangI I serta os digiti III. Data was analyzed using Analysis of Variance (ANOVA) then continued with Post Hoc Duncan test. The growth point reached its maximum when the 21 day old chicken was indicated by an optimal point and followed by slowing growth. At this point triggers the formation of meat in the Lohmann strain broiler chicken before the chicken reach the growth limit.
