Cattle and Sheep Growth USING ASSORTATIVE MATINGS TO MAXIMISE SALES OF HOMOZYGOUS FAVOURABLE SHEEP SIRES, A SIMULATION STUDY
نویسندگان
چکیده
A stochastic simulation model of a sheep breeding program is used to show how assortative matings can increase the number of rams sold which are homozygous favourable for a major gene. The commercial implications of such a strategy are discussed in comparison with strategies focused more on increasing gene frequency. Long term inbreeding is unaffected while the lost response to selection for polygenic merit is substantially reduced, when homozygosity is increased through assortative mating, rather than though increasing the gene frequency in the population and using random mating.

Random regression models for estimation of covariance functions of growth in Iranian Kurdi sheep
Body weight (BW) records (n=11,659) of 4961 Kurdi sheep from 215 sires and 2085 dams were used to estimate the additive genetic, direct and maternal permanent environmental effects on growth from 1 to 300 days of age. The data were collected from 1993 to 2015 at a breeding station in North Khorasan province; Iran. Genetic parameters for growth traits were estimated using random regression test-...

This study was carried out to determine the presence and frequency of Anaplasma ovis and Anaplasma marginale in sheep and dairy cattle in West-Azerbaijan province, Iran. A total number of 200 blood samples were randomly collected via the jugular vein from apparently healthy cattle (100) and sheep (100). The extracted DNA from blood cells was screened using genus-specific (Anaplasma...
متن کاملTransferrin types and reproduction in sheep.
Transferrin types were determined for flocks of Finnish Landrace, Clun Forest, Soay and Merino sheep and gene frequencies were calculated. Analysis of ratios of transferrin types in segregating matings of Finnish Landrace and Clun Forest revealed a significant excess of heterozygotes in matings of heterozygous rams with heterozygous and with homozygous ewes. In Finnish Landrace, matings of shee...

Background and aims: Toxoplasma gondii is an obligate intracellular parasite which has the potential toinfect all warm-blooded animals. Sheep and cattle play a main role in the economy and their infectionto T. gondii, besides economic losses, can cause the infection of humans through the consumptionof raw meat and other products. In this study, we aimed to survey the prevalenc...

Background: Cystic echinococcosis (CE), known as hydatid cyst, is a zoonotic parasitic infection caused by the larval stage of Echinococcus granulosus (E. granulosus). Antigen B, the major component of hydatid cyst fluid, is encoded by members of a multigene family. The present study aimed to evaluate the genetic diversity of the gene encoding antigen B8/1 (EgAgB8/1) among the main intermediate...
