Effectiveness Of Two Breeding Methods With Estrus Synchronization In Ettawa Grade Goats Using Controlled Internal Drug Release

Abstract

Dairy goats is a new commodity for most people in Indonesia and has a good development prospects. Dairy goats were developed in Indonesia is Peranakan Ettawa (Ettawa Grade Goat) and generally still more dominant as a source of meat compared to the milk source. This goats are very adaptive topography in Indonesia. This goat is widespread in rural areas and is usually maintained for the purpose of saving as well as livestock. Within two years, Ettawa Grade Goat can give birth three times with each time average of two kid. Traditional farming business are generally only used as a sideline so that maintenance management was not too much attention. This has led to economic losses and aggravate subsequent descendants. The failure of the process of reproduction is often a problem on the farm people that led to the collapse lamb birth three times in two years, so the kidding interval will be long. This problem is very detrimental to farmer. Reproductive ability is influenced by many factors, including the reproductive management that are not mapped, the high incidence of silent heat (estrus quiet), the quality of the frozen sperm is used and interference with the function of the reproductive organs. Good reproductive management accompanied by the application of reproductive technology is a shortcut to accelerate the achievement of objectives. For farmers who have applied the principles of agribusiness, especially for dairy goat farmers will feel comfortable if they can produce throughout the year. Businesses that are used to cope with the failure of the process of reproduction such as increasing intake of feed nutrients and synchronize estrus. Estrus synchronization is a method for manipulating and uniformity of the estrous cycle. Goat can be expected estrus at the same time, so that will facilitate the management and maintenance of breeding. Implementation of estrus synchronization can be done by giving luteolitik agents (prostaglandin and estrogen) or progesterone either single or in combination with other hormones. The progesterone which has been used among other intravaginal progesterone intravaginal device (PIRD) and Controlled Internal Drug Release (CIDR). Controlled Internal Drug Release can be widely used to control the estrous cycle in cattle, buffaloes, goats and sheep. This treatment has been used for years as a method for controlling the estrus cycle in domestic ruminants. One attempt to improve reproductive efficiency is by improving the quality of breeding. Improved quality of marriage includes recording, time of mating and mating method. Methods of mating there are two ways, the natural mating and artificial insemination (AI). The AI program is very profitable for farmers because without maintaining superior male can result superior lamb. Utilization of reproductive technologies that synchronize estrus in goats has not been done in Indonesia. Utilization of estrus synchronization was limited to research, so the use CIDR should be considered to support the development of goats in Indonesia
