The influence of carcass backfat and intramuscular fat level on pork eating quality
Autor: C. C. Warkup, Michael Ellis, P. J. Blanchard, M. B. Willis
Publikováno v: Journal of the Science of Food and Agriculture. 80:145-151
To evaluate the contribution of fatness level towards pork eating quality, carcass and meat eating quality data were analysed from 721 pigs of three genotypes (with 0, 0.25 and 0.50 Duroc inclusion level). Animals (entire male and female) were reared

Multivariate REML estimates of genetic parameters of monthly test day milk production traits in first parity Iranian Holstein cows with the use of a repeatability test day model
Autor: H. Farhangfar, P. Rowlinson, M. B. Willis
Publikováno v: Proceedings of the British Society of Animal Science. 2003:139-139
In practical dairy cattle breeding programmes, usually a small number of animals (selected from a large population) have a major influence on the genetic gain of the concerned population over a period of time (Hofer, 1998). Candidate animals are usua

Comparison of Canadian Holstein × British Friesian and British Friesian steers for beef production. 1. On-farm performance
Autor: A. J. Chalmers, M. B. Willis, P. Rowlinson, P. L. Baber
Publikováno v: Animal Science. 38:399-405
A comparison was undertaken of 92 Canadian Holstein × British Friesian (HF) and 93 British Friesian (F), autumn born, male calves on three typical United Kingdom production systems. These were: intensive barley beef system (BB); a grass/cereal 18-mo

Factors affecting calving difficulty and gestation length in cows mated to Chianina bulls and factors affecting the birth weight of their calves
Autor: A. Wilson, Christopher Davison, M. B. Willis
Publikováno v: Animal Science. 22:27-34
SummaryImported semen from 10 Italian Chianina bulls was used to inseminate beef and dairy cattle throughout England and Southern Scotland. A total of 2134 records of calving performance were subjected to least squares analyses. Dystocia score was si

Control of inherited defects in dogs
Autor: M. B. Willis
Publikováno v: Journal of Small Animal Practice. 30:188-192
Canine defects can be divided into several main groups: autosomal recessives, autosomal dominants, sex-linked traits, threshold characters and polygenic traits. Few are dominant, as early onset dominant defects are easily eliminated. Autosomal recess

Factors affecting birth weight of Santa Gertrudis calves
Autor: M. B. Willis, A. Wilson
Publikováno v: Animal Science. 18:231-236
SUMMARYBirth weights of 568 Santa Gertrudis calves by 15 sires out of 111 different dams over a 14-year period were obtained from a herd in Cuba. Year of birth, season of birth, sex of calf, sire and dam all had highly significant influences upon bir

Autor: M. B. Willis, A. Wilson
Publikováno v: Animal Science. 18:43-48
SUMMARYOver a 15-year period 1011 calving intervals from 187 Brahman (B) cows and 687 calving intervals from 146 Santa Gertrudis (SG) were examined. Year of calving significantly affected intervals in both breeds. Season of calving and parity of dam
