Effect of genotype and non-genetic factors on growth traits and survival rates in Turkish indigenous Hair goats and their first cross with Boer bucks

Abstract

The aim of this study was to determine the effects of genotype and non-genetic factors on the growth traits and survival rates of Turkish indigenous Hair goats (n=63) and their first crosses with Boer bucks (n=91), reared under a semi-intensive management system in the Van province of Turkey. The live weights of the kids at birth and on days 30, 60, 90, 120, 150, and 180 were determined to be 3. 64, 8.89, 13.99, 18.97, 23.62, 27.22 and 30.44 kg, respectively. The average daily gains in the pre-weaning, post-weaning and overall periods were 171.09, 136.43 and 148.34 g, respectively. The multiple-birth kids had lower survival rates than the single-birth kids (P<0.01). As a result, it may be recommended to Hair goat breeders in the region to use Boer bucks in cross-breeding in order to ensure a better growth performance from the kids; to apply a sustainable selection program; and to improve management conditions. In addition, the data obtained from this study may be used as a model for designing policies on Hair goat breeding in this region.

Farmers’ perception and willingness to consume goat milk and goat milk products: A case study of the central Eastern Cape, South Africa

“…Considering the human population growth trend, the emerging sub-sector in South Africa including goat production may benefit from this prospect. Most rural areas in developing countries raise indigenous goats on a large scale for meat, milk and skin among others (Bolacali et al 2017).…”

Relationship between muscle fiber characteristics and meat quality parameters in Turkish native goat breeds

“…The goats are now reared all over the world. Goat breeding is widespread in Turkey due to the geographic-economic conditions of the country, the historical accumulation of agricultural experience, and the traditions and customs of the Turkish people (Bolacali et al, 2017). Turkey has about 10 million goats and 9 different breeds (Turkstat, 2016).…”

Factors Affecting Milk Yield and Composition of Indigenous Balkan Goat Breed Reared in Semi Extensive Conditions

“…Goats are reared in different geographical and climatic conditions and play very important role in less favored areas (Memisi et al 2004, Bolacali et al, 2017. The abundance of goat populations in the harsh, arid, semiarid areas most likely reflects their good adaptation to such environments, especially indigenous breeds (Kumar et al 2010).…”
