In Hanwoo progeny testing
, each batch of animals is measured at an approximate 90 days interval when all animals attain a target test age on average.
From the 2008 Select Sires group of bulls evaluated using traditional progeny testing
, seven genomic tested sires graduated to proven status from the top 10%, and six bulls returned from the top 20%, reflecting a 26% and 21% respective return from 277 sampled Holstein bulls.
De Sousa-Vieira and Milligan (1999) examined intra-row plant spacing as a source of variation affecting the efficacy of progeny testing
and family selection.
As the genetic threshold has increased over the past four years, some young bulls have not completed progeny testing
owing to lower identified profiles.
could be used to identify and separate genetic sterility from CMS, and to isolate a near equivalent CMS counterpart to the male-fertile, O-type.
The only way you improve any breed is by progeny testing
, but, at the moment, only about 20 per cent of the jump-racing population are mares.
41 in Hanwoo steers slaughtered at 24 months of age after the end of progeny testing
or in Japanese Black steers (Osawa et al.
The opportunity to select the best available young sires for progeny testing
will benefit breeders as well as the AI industry.
Various programmes aimed at providing maximum support services to livestock farmers include establishment of genetic semen laboratories, progeny testing
programme through outreach, upgradation of tehsil HQ hospitals, mobile dispensaries and new vet dispensaries at each union council level.
A programme of progeny testing
inspired by the county livestock officer WD Griffiths and Gwynn Williams of the University of Wales Bangor, a leading authority on sheep breeding, set the pace.
Since sunflower NMS is controlled by single recessive genes, the presence of the MS allele in backcrossed lines (heterozygotes) can only be detected by progeny testing
Breeders now rely on a process called progeny testing
, where the plants' offspring (progeny) are tested for resistance to the virus in a greenhouse.
Since 1990, the application of ultrasound measurements were extended to estimate genetic parameters for young bulls and heifers, so as to reduce time and cost for progeny testing
(Shepard et al.
This tremendous advancement provides double the current level of reliability and is getting closer to a favourable comparison with progeny testing
which offers 85-95% reliability.
