Effect of heterozygosity at the double-muscle locus on the performance of market calves
Autor: Moira Tanaka, W. C. Rollins, R. B. Thiessen, F. D. Carroll
Publikováno v: Hilgardia. 48:1-26
Trials conducted at the University of California (Davis) demonstrated the feasibility of producing market calves heterozygous for the double-muscling gene. On average, these calves compared to normal calves reached market weight at an earlier age, ha

An analysis of pre-weaning deaths in rabbits with special emphasis on enteritis and pneumonia. I. Non-genetic sources of variation
Autor: W. C. Rollins, R. B. Casady
Publikováno v: Animal Science. 9:87-92
Non-genetic sources of variation in pre-weaning death losses due to enteritis or pneumonia have been investigated using records of 15,329 rabbits born during the years 1946–61 in the random bred colony at the U.S. Rabbit Experiment Station at Fonta

Performance of Charbray and Hereford cattle and crosses between them
Autor: W. C. Rollins, F. D. Carroll
Publikováno v: Animal Science. 7:119-126
SUMMARYThis experiment was designed to compare the average performance of Charollais-Hereford and Hereford-Charbray calves with the average performance of purebred Hereford and Charbray calves as a measure of hybrid vigour in various traits of econom

Body size and conformation in identical twin cattle
Autor: C. S. Taylor, W. C. Rollins
Publikováno v: Animal Science. 5:77-86
SUMMARYThe variation and covariation of 12 linear body measurements within 60 pairs of monozygotic twin heifers is analysed in terms of a twin's mean size over a two-year period.Possibly all the covariation, and two thirds, on average, of the variati
