Body weight and its effect on other morphometric characters in White Leghorn pullets l33

The aim of this study was to determine the effect of body weight on other morphometric characters in White Leghorn pullets L33. The study lasted for 6 weeks using 300 pullets (11-16 weeks old) equally distributed in two experimental groups: I: expected body weight (865.6 ± 13.3 g); II: overweighed (920.1 ± 37.3 g). Body weight, tarsus length and distances between pubic bones and from keel to pubis were determined weekly. The Mann-Whitney U test (p<0.05) was used to compare means between groups. Degree of uniformity in body weight in both groups was considered excellent (2.6 and 4.8% for group I and II, respectively). Significant difference between groups was observed in the tarsus length and distance from keel to pubis (p<0.0001), but not on the distance between pubic bones. Also, positive correlation between body weight and other morphometric variables was observed, although only 25.2% of the tarsus length was determined by body weight. It is concluded that body weight has a direct effect on tarsus length in White Leghorn pullets L33, which is potentiated in overweight birds.

El objetivo del presente estudio fue determinar el efecto del peso corporal sobre otros caracteres morfométricos en pollitas White Leghorn L33. Se trabajó con 300 pollitas por seis semanas a partir de la semana 11 de edad. La mitad (grupo I) tenían el peso esperado para su edad (865.6 ± 13.3 g) y la otra mitad (grupo II) estaban con sobrepeso (920.1 ± 37.3 g). Se registró semanalmente el peso corporal, largo del tarso, y distancias entre pubis y de quilla a pubis. Se utilizó la prueba U de Mann-Whitney (p<0.05) para comparar las medias entre grupos. La uniformidad en el peso corporal de ambos grupos fue considerada como excelente (2.6 y 4.8% para el grupo I y II, respectivamente). Se observó diferencia significativa entre grupos en el largo del tarso y la distancia de quilla a pubis (p<0.0001), pero no en la distancia entre pubis. Asimismo, se observó correlación positiva entre el peso corporal y las otras variables morfométricas, aunque solo el 25.2% del largo del tarso estuvo determinado por el peso corporal. Se concluye que el peso corporal tiene un efecto directo sobre el largo del tarso en pollitas White Leghorn L33 en desarrollo, el que se potencializa en aves con sobrepeso.
