production, reproduction, management and economic parameters resulted from recordings of 5 flocks comprised of 720 heads of native goats during annual cycle of reproduction in transhumance, village and farming systems were employed to determine the performance of traits, cost-profit analysis as well as breeding objective. the overall mean for number of salable kid per goat in transhumance, vill...
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...
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
Alpine and Damascus goats were crossbred in a private goat farm established Adana that engaged raising order to develop genotype will give more milk the hot humid climate summer of Çukurova region. In this study, growth characteristics between birth weaning kids compared with kids. The animal material for study consisted 136 head pure 32 as well their fed dams' (average 0.70 litre / day) first ...
abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
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...
The research was conducted with the aim of knowing repeatability estimate and Most Probable Producing Ability (MPPA) value weaning weight female Saburai goats. This from July to September 2019 in Gisting, Sumberejo, East Kota Agung districts, Tanggamus regency, which is development area for goat seeds. used a survey method. data form primary obtained breeders through questionnaires secondary da...
Although future production of dairy goats is influenced by kid-rearing practices, little known regarding which practices maximize kid growth, welfare, and success. The objectives this survey study were to (1) identify common rearing Canadian commercial goat farms evaluate their associations with 6 farm performance indicators (2) determine if could be grouped management style on the basis compar...
