Estimation of genetic parameters for growth traits and Kleiber ratios in Boer x Central Highland goat

Influence of maternal and additive genetic effects on offspring growth traits in Beetal goat

“…Higher estimates for genetic correlation for BWT with other traits than current study were reported by Gowane et al (2011) in Sirohi goat (0.20-0.47), Baneh et al (2012) in Naeini (0.49-0.61) and Barazandeh et al (2012) in Raini Cashmere goat (0.53-0.55). Genetic correlation estimates for WT3 and WT6 with other traits were in accordance with the findings of Gowane et al (2011) in Sirohi, Moghbeli et al (2013) in Raini Cashmere and Tesema et al (2020) in Boer x Central Highland goat.…”

“…In case of post-weaning traits, maternal influence was found to be negligible or absent, which were contrary to findings of Gowane et al (2011) in Sirohi and Tesema et al (2020) in Boer x Central Highland goat. The moderate estimate of direct h 2 for WT6 (model 1) in our study was higher than reports of Boujenane and El Hazzab (2008), Gowane et al (2011), Petrović et al (2012), Mohammadi et al (2012 and Tesema et al (2020) in different goat breeds.…”

“…The direct h 2 estimate for WT9 and WT12 was in accordance with the estimate by Snyman and Olivier (1996) in Angora goat, Boujenane and El Hazzab (2008) for Draagoat, Roy et al (2008) in Jamunapari goat. However, high estimate than current study was reported by Schoeman et al (1997) in Boer goat, Rashidi et al (2008) in Markhoz goat and Tesema et al (2020) in Boer…”

“…The estimates for ADG1 and KR1 under the present study were higher than the estimates of Zhang et al (2009) in Boer, Gowane et al (2011) in Sirohi, Barazandeh et al (2012) in Raini Cashmere and Rout et al (2018) in Jamunapari goat, whereas Tesema et al (2020) in Boer x Central Highland goat (0.26 and 0.32, respectively) published similar range of estimates. Direct heritability estimates for ADG2 and KR2 were confirmation with estimates reported by Tesema et al (2020) in Boer x Central Highland goat (0.17 and 0.23). Mohammadi et al (2012) in Raini Cashmere goat (0.42) accounted higher direct h 2 estimates for ADG2.…”

“…In more comprehensive model 4, we found h 2 = 0.05, m 2 = 0.04 and c 2 = 0.07, indicating that the permanent environmental effects constitute more of the direct ef- For WT3 trait, moderate h 2 indicated that the expected response to phenotypic selection would be exploited for this trait. Our estimate was higher than those published in literature by Schoeman et al (1997) in Boer (0.18), Boujenane and Hazzab (2008) in Draa (0.19), Roy et al (2008) in Jamunapari (0.18), Rashidi et al (2008) in Markhoz (0.15), Maghsoudi et al (2009) in Iranian Cashmere (0.20), Zhang et al (2009) in Boer (0.23), Rashidi et al (2011) in Markhoz (0.16), Gowane et al (2011) in Sirohi (0.12), Baneh et al (2012) in Naeini (0.19) and Gholizadeh et al (2010) in Raeini (0.23) and Tesema et al (2020) in Boer x Central Highland goat (0.31). Higher estimates than the current study were reported by Mourad and Anous (1998) in Common African and Alpine crossbred kids (0.49) and AlShorepy et al (2002) in Emirati goat (0.34).…”
