The objective of the present study was to evaluate the effects of inbreeding on average daily gains and Kleiber ratios in Moghani sheep. Traits included average daily gain from birth to 3 months (ADG1), average daily gain from birth to 6 months (ADG2), average daily gain from 3 months to 6 months (ADG3), average daily gain from 3 months to 9 months (ADG4), average daily gain from 3 months to ye...

The aim of this study was to investigate a recessive genetic component in susceptibility to osteoporosis (OP) by comparing its prevalence in isolated villages of three Croatian islands: Brac, Hvar and Korcula with different levels of inbreeding. A random sample of 20-30% adults from 14 villages was obtained, including a total of 1,389 examinees. The average inbreeding coefficient (F) of examine...

AST and JONES (1919) and CASTLE (1930) reviewed the significant experiE ments with plants and laboratory animals that contributed to the formulation of the modern viewpoints concerning the effects of inbreeding. The phenomena associated with inbreeding: decline in vigor, increased uniformity within the inbred stock, increased prepotency in outside crosses, isolation of abnormal types, etc., wer...

The aim of this study was to describe inbreeding and population structure in Sangsari sheep breeding station. For this reason, data from 7028 Sangsari sheep which were collected during 1987-2014 in Sangsari sheep breeding station located near to Damghan city, Semnan province were used. Lambs born during 2010-2014 were considered as reference population. The genetic structure analysis of the pop...

population mean heterozygosity (i.e. 12 data points). Both analyses were statistically significant, indicating that populations with low heterozygosity have relatively abnormal sperm. Two alternatives to inbreeding depression are consistent with this result: a third, unknown factor causes some populations to have low heterozygosity and relatively abnormal sperm; for instance, environmental hete...

Genetic diversity in the Finnsheep breed was analyzed by quantifying the demographic trends, the depth of known pedigree, effective population size, and the amount of inbreeding, as well as identifying candidate rams within the current population for future breeding and conservation purposes. Pedigree records of 148,833 animals with a pedigree completeness coefficient > or =0.60 and born from 1...
