A study of polymorphic systems in Nelore cattle (Bos taurus indicus L.) associated with beef production. II Transferrins, weights and weight gain of animals submitted for performance testing and scrotum circumference


, : A study of polymorphic systems in Nelore cattle (Bos taurus indicus L.) associated with beef production. II Transferrins, weights and weight gain of animals submitted for performance testing and scrotum circumference. Boletim de Industria Animal 54(1): 13-20

A sample of 125 males from the Sertaozinho Experimental Station (SP), submitted for performance testing, was used to observe the Castle-Hardy-Weinberg equilibrium for transferrin polymorphism. Another objective was to verify possible relationships with growth traits. Statistical analysis was performed by least-squares for unbalanced subclass numbers and chi superscript 2 analysis was used to test for Castle-Hardy-Weinberg equilibrium.

Haemoglobins: body weight and gain from birth to the second calving. For 114 Nelore cows kept under range conditions in Brazil, body weight at 18 months of age averaged 258.45, 258.43 and 295.85 kg respectively for females with Hb type AA, AB and BB, and body weight at 1st calving averaged 405.83, 411.83 and 451.84...

Biometry of the testis. This study was carried out with 38 steers, with ages varying from 426 and 751 days. The young bulls were from different races; Nelore (n=19), Guzera (n=9), Caracu (n=6) and Gir (n=4), and divided in seven different genetic groups according to the...
