With the main objective of improving Tajik mohair quantity and quality, frozen semen from eight top performance tested Texan Angora bucks was imported and used on 459 selected local goats from 11 farmers in two insemination seasons. Conception rates in both seasons were very low. Sixty six Texan ...

Based on the multiple utility of goats as well as multiple resources employed, broader productivity criteria were developed and applied to evaluate subsistence goat production. The results showed that, under the improved subsistence production, crossbred goats did not generate any more Unit Net B...

Individual labour input into goat husbandry was enumerated for a period of one year from a total of 71 sample households. Comparison was made at household level. Results show that women contribute a proportional share of labour and their share changes in response to household characteristics rela...

Goats and sheep are versatile domesticates that have been integrated into diverse environments and production systems. Natural and artificial selection have shaped the variation in the two species, but natural selection has played the major role among indigenous flocks. To investigate signals of ...

A meta-analysis of 84 published reports on goats was conducted to calculate weighted and unweighted average direct heritability (ha2), maternal genetic effect (hm2), common environmental effect (c2), repeatability (R), genetic (rg) and phenotypic (rp) correlations for growth, reproduction and mil...
