- Incidence and heritability of black wool spots in Romney sheep
Therefore, the objective of this study was to determine the additive genetic effects on BWS detected by weaning and by 1 year of age, and to determine if selection against spotted sheep was successful in reducing the genetic propensity for the.
- Selection for or against facial eczema susceptibility in Romney
A different dose rate of sporidesmin was used for performance expressing results as a breeding value for logeGGT.Analyses took account of one dose rate used in the R flock and in half of the C flock, and a second (lower) dose rate used in the remainder.
- Genetics of resilience to nematode parasites in young Romney sheep
The results confirm that breeding for resilience, using either approach, should ultimately lead to flocks whose lambs are able to maintain both better growth rates and lower dag scores under nematode challenge, and thus require a lower frequency of.
- 1993 LIFE MEMBERSHIP
It is a coincidence, but then could be a factor associated with Dr Wickham s later involvement with Drysdale sheep, that his mother lived close to the farm of Mr Neilson at Karere near Palmerston North where in 1931 Dr Dry found the particularly hairy.
- Correlated responses to selection for or against facial eczema
As a result of lower numbers in the S than R lines, and difficulties in increasing the S ewe numbers, 200 unrelated Romney ewes from Whatawhata Station, in the Waikato region, were mated to elite Demonstration lines In 1982, two additional Romney lines.
