Angus (A), Brown Swiss (S) and A X S reciprocal F t (AS) dams were mated to A, S and AS (also reciprocal F 1 ) sires resulting in nine breed groups of progeny with varying proportions of Angus and Brown Swiss breeding. Breed group of dam and of sire significantly influenced birth weight, preweaning daily gain, weaning weight, 205-d weight, condition score and frame size. The means for birth wei...

a study to evaluate the reproductive performance of abergelle goat was carried out at sekota district of amhara national regional state. on-farm flocks from two peasant associations were monitored for two years to collect data. data collected included identification number of doe and kid, birth / kidding date, kid birth weight, sex of kid, post partum doe weight, litter size, parity of doe. dat...

Breeding programs to promote the productivity of Indonesian local goats (i.e. Kacang Goats) in various regions have been carried out by cross-breeding with predominant breeds meat world such as Boer Goats. Currently, considering that genotypes cross-bred goat (namely Boerka Goat) spread and farmed farms throughout country, it is necessary evaluate increase achieved. This study aims investigate ...

the aim of the peresent study was to find the optimum weaning time to shift pikeperch larvae feeding from live food to the artificial feed. in this experiment, pikeperch larvae were fed with seived pond zooplankton (mainly rotifers) and artemia nauplii from the first feeding day to day 16 of post-hatching. then three weaning times were used on day 16 (w16), day 22 (w22), and day 28 (w28) of pos...

Data were 876 birth records and 727 weaning records of straightbred and F3 crossbred calves produced in the third generation of a five-breed diallel. Among straightbreds at birth, Holstein calves were heaviest and widest at the shoulders and hips. Jersey calves were lightest and narrowest at the hips, and Brahman calves were narrowest at the shoulders. Holstein crosses tended to be larger at bi...

The present study was performed to study the effect of inbreeding on the pre-weaning growth traits including the birth weight (BW), weaning weight (WW), average daily gain (ADG), Kleiber ratio (KR) and lamb survival from birth to weaning (SUR) in Baluchi, Iran-Black and Zandi sheep. Significant positive inbreeding trends were found only for Baluchi and Iran-Black breeds as 0.038 and 0.278, resp...

lamb survival is one of the major factors affecting overall sheep productivity. lamb survival affected by environmental effect such as management, birth-type, year, season of birth, dam-age, maternal behavior, genotype of parents, and birth-weight. the data comprised 9989 records were collected from 1989 to 2009 in iranian baluchi sheep at abbasabad sheep breeding station. four binary traits cr...

In this study production, reproduction, population, management and economic parameters resulted from recording of 7 flocks with size 57 to 400 and 721 heads of camels in a cycle of reproduction, during three years from 2011 to 2013 were used to find out of the economic values of important traits in one hump camel in desert areas rearing system. The economic traits that appeared in profit equati...
