Reproductive Techniques of Potential Use to Goat Breeders
نویسنده
چکیده
The reproductive techniques of potential use to goat breeders have been developed in other species, notably the sheep, and have been applied to goats with only minor modifications necessitated by species differences. The Angora industry, and to a lesser extent the cashmere industry, have lent themselves readily to the relatively widespread use of reproductive techniques because of three major factors:

Modern Concept in Optimizing Reproductive Efficiency of Seasonal Breeders
Accepted: 29/09/2015 Abstract The control and manipulation of reproduction is the subject of scientific interest for many years. High level of reproductive performance can be achieved under optimum managemental conditions because reproduction is directly affected by various managemental factors. Manipulation of these factors causes changes in reproductive performance. Seasonal breeders are anim...

This study conducted to determine the effect of guanidino acetic acid consumption and management methods on the enhancement of aged rooster's reproduction. A total of 486 broiler breeders (Ross 308) were used in a 3 × 3 factorial experiment from week 41 to 62. Three levels as 0, 1200, and 1600 (mg/kg) of guanidino acetic acid, as a precursor of creatine (CreAmino) in combination with three mana...

Background Little is understood about the regulation of gene expression during early goat embryo development. This study investigated the expression profile of 19 genes, known to be critical for early embryo development in mouse and human, at five different stages of goat in vitro embryo development (oocyte, 8-16 cell, morula, day-7 blastocyst, and day 14 blastocyst). MaterialsAndMethods Stage-...
متن کاملRecent Advances in Goat Reproductive Biotechnology in Malaysia
Recent advances in reproductive endocrinology and physiology of mammals, molecular biology and genetic engineering have enhanced the expansion of the field of animal reproductive biotechnology. To date, many reproductive techniques have been applied in livestock animals such as cattle, sheep and pigs. Nevertheless, the application of such techniques is still limited in goat. This paper aims to ...
متن کاملThe “Male Effect” Onestrous Synchronization and Reproductive Characteristics of Female Markhoz Goat during the Breeding Season
One hundred female Markhoz goats (42±5 kg) were used to investigate the ‘male effect’ on estrous synchronization and reproductive characteristics of female goat during the breeding season. This was carried out in three separate experiments. In the first experiment, forty female goats were used in 4 groups with different distance from the male goats (i.e. source of pheromone secretion); A1 (1 me...
