Resumo: | The AA. have studied, in this paper, the correlation of egg production in yearling R. I. R. pullets and the difference between the pelvic bones, an between the pelvic bones and keel. The distances between those bones were measured by the fingers. It was suggested an index = spread of pelvic x spread of keel bone. These three data were compared with the last 30 days production and with the production to date - six months. Comparisons have been made with 285 pullets. The AA. have concluded: (a) there is a positive correlation between the spread of the pelvic bones and the last 30 days (r = + 0,23 and pr = + 0,16); (b) there is not correlation of the distance between the pelvic bories to the keel and the last 30 days (r = + 0,11 and pr = - 0,01; (c) there is positive correlation of the distance between the pelvic bones to the keel and last six months production (r = + 0,27 and pr = + 0,19); (d) the correlation of the index sugested pratically equals correlation between pelvic bones (r = + 0,27 and pr = + 0,19); (e) correlation between last 30 days production and the total egg production is high (r = + 0,55 and pr = 0,53). Is is stated that spread of the pelvic bones is a low index of actual production and the distance of the keel a low index of total egg production in R. I. R. pullets. The last month real production is a better index of the total egg production. |

The AA. have studied, in this paper, the correlation of egg production in yearling R. I. R. pullets and the difference between the pelvic bones, an between the pelvic bones and keel. The distances between those bones were measured by the fingers. It was suggested an index = spread of pelvic x spread of keel bone. These three data were compared with the last 30 days production and with the production to date - six months. Comparisons have been made with 285 pullets. The AA. have concluded: (a) there is a positive correlation between the spread of the pelvic bones and the last 30 days (r = + 0,23 and pr = + 0,16); (b) there is not correlation of the distance between the pelvic bories to the keel and the last 30 days (r = + 0,11 and pr = - 0,01; (c) there is positive correlation of the distance between the pelvic bones to the keel and last six months production (r = + 0,27 and pr = + 0,19); (d) the correlation of the index sugested pratically equals correlation between pelvic bones (r = + 0,27 and pr = + 0,19); (e) correlation between last 30 days production and the total egg production is high (r = + 0,55 and pr = 0,53). Is is stated that spread of the pelvic bones is a low index of actual production and the distance of the keel a low index of total egg production in R. I. R. pullets. The last month real production is a better index of the total egg production. |
