“…These results can be explained by the high heritability of growth and weight traits in Boer goat kids (Menezes et al, 2016). One of the major effects on the growth of goats is the adult live weight of the mother and father goats.…”

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.

“…Regarding the litter size of goats, selection programmes have generally considered only the phenotypic and pedigree information of the animals (Shrestha and Fahmy 2007;Mohammadi et al 2012;Castañeda-Bustos et al 2014;Zhou et al 2014). Due to the low heritability of litter size (0.08-0.18), its rate of genetic improvement is slow (Hamed et al 2009;Gunia et al 2010;Santos et al 2013;Menezes et al 2016). Therefore, the inclusion of genomic information in the genetic evaluation of prolificacy in goats would greatly increase the accuracy of selection.…”

“…Therefore, improving litter size can also increase annual genetic progress in other economically important goat traits (Sarmento et al 2010;Santos et al 2013). However, the improvement of reproductive traits by traditional selective breeding methods has proven to be difficult due to their sexlimited nature and low heritability, which varies from 0.08 to 0.18 (Hamed et al 2009;Gunia et al 2010;Santos et al 2013;Menezes et al 2016). While rapid rates of genetic progress for growth-related or milk traits have been achieved in small ruminants, a relatively lower rate of progress is possible for traits that are measured later in the life of females, such as reproductive ability (Mrode et al 2018).…”

Litter size, or prolificacy, in goats is defined as the number of kids born per doe kidding. Improving litter size through selection not only directly enhances producer profitability as more progeny can be marketed but can also increase genetic gains in other traits due to greater selection intensity. However, most traits associated with reproduction have low heritability, and genetic improvement will be slow if the selection is based on one or a few phenotypic records. In the absence of a genetic evaluation programme with extensive pedigrees and performance recording, phenotypic selection for litter size is not promising. Advances in molecular genetic techniques may serve as an alternative to increase genetic progress in prolificacy. Several techniques have been developed to elucidate the mechanisms involved in phenotypic expression at the DNA level. Although recent research has identified genomic regions associated with several production traits in goats, litter size has not been extensively researched. Nevertheless, recent advancements in molecular genetic have created new opportunities for the improvement of litter size in goats. The development of next generation molecular tools to identify genomic genetic variants has made it possible to apply whole-genome scanning techniques, genomewide association studies, and genomic selection to improve goat prolificacy.

“…Boer goat was a beef type with fast body growth, good meat quality, and parasitic tolerance (Chong et al, 2019;Elieser et al, 2012;García-Muñiz et al, 2019). Boer has weaning weights 23.4±9.7 kg at the age of 112 days (Menezes et al, 2016) and adult male 120-150 kg at the age of 2-3 years (Nurgiartiningsih et al, 2006). Boer and Kacang goat crosses were called Boerka goat that a new superior goat (Ginting and Mahmilia, 2008).…”

This study aimed to identify the variation of 5’UTR Myostatin (MSTN) gene and its association to body weight in Boer, Kacang, and Boerka goats. DNA samples were obtained from 149 heads of the goats from the Indonesian Goat Research Center, Sungei Putih, North Sumatera. Polymorphism identification was conducted by direct sequencing and PCR-RFLP with DraI as the restriction enzyme for indel g.1256/TTTTA. Analysis of variance for body weight was carried out using the General Linear Model (GLM). The 5’UTR MSTN gene|DraI was monomorphic in Kacang but polymorphic in Boer and Boerka. Genotype frequencies for Boer 0.40(AA), 0.43(AB), 0.17(BB); Kacang 1.00(AA); Boerka 0.53(AA), 0.37(AB), 0.10(BB). The allele frequencies for Boer 0.62(A), 0.38(B); Kacang 1.00(A); Boerka 0.72(A), 0.28(B), respectively. AB was the most frequent genotype among Boer, but AA was the most frequent in Kacang and Boerka. Indel g.1256/TTTTA has a significant effect (P<0.05) only on birth weight (BW) of Boer, but no significant effect on other bodyweight parameters both in Boer and Boerka.AA genotype has the highest BW (P<0.05) than AB, but it’s not significantly different from BB. Indel g.1256/TTTTA could be used as a genetic marker for the birth weight of Boer but not in Boerka goats.
