in this study, production, reproduction, management and economic parameters deduced from recordings of 5 flocks with 720 heads of native goats during an annual cycle of production in transhumance, village and farming systems were employed to determine the traits' economic values. the economic values of the traits were estimated, using maximizing profit, revenue per cost as well as minimizi...

In the present study a deterministic bio-economic model was used to estimate economic values for reproduction traits (conception rate, twining rate and litter size), production traits (body weight of kid sold at 6.5 months, annual cashmere weight, body weight of doe and annual milk yield) and longevity (survival of doe, survival of kid until weaning and survival of kid until sale age at 6.5 mon...

Boer, Kiko, and Spanish meat goats were semi-intensively managed in a complete 3-breed diallel mating scheme to evaluate genetic effects on preweaning kid performance. Over a 6-yr period, 1,547 kids were born in March and May with 1,173 kids raised by their dams to weaning at 3 mo of age. March-born kids were lighter (P < 0.01) at birth, but had greater (P < 0.01) preweaning ADG and survival ra...

In this study a bio-economic model was used for a flock with 195 breeding ewes and 20 rams to determine economic values of important traits in Zel sheep of Golestan including litter size, pre-weaning survival, post-weaning survival, ewe survival, birth weight, weaning weight, yearling weight, ewe mature weight, dressing percentage, conception rate and wool weight. In this model, fixed environme...
