Estimates of (co)variance components for productive and composite reproductive traits in Iranian Cashmere goats

Estimates of (co)variance components and genetic parameters for growth traits in Sirohi goat

“…Estimates for c 2 within the range of current study were reported by Schoeman et al (1997) for Boer goats (0.07), Rashidi et al (2008) for Markhoz goats (0.09), Boujenane and El Hazzab (2008) in Draa goats (0.08), Roy et al (2008) for Jamunapari goats (0.09), Kantanamalakul et al (2008) for mixed goat population (0.02) and Maghsoudi et al (2009) for Iranian Cashmere goats (0.067). Al-Shorepy et al (2002) obtained c 2 estimate of 0.20 for Emirati goats.…”

“…Estimates of genetic and phenotypic correlations obtained in the present study are higher than Hermiz et al (1997), whereas these estimates were in agreement with the earlier estimates for pre-weaning traits by Al-Shorepy et al (2002), Supakorn and Pralomkarn (2009) and Maghsoudi et al (2009). Same trend was also observed for earlier estimates by Mourad and Anous (1998), Portolano et al (2002), Boujenane and El Hazzab (2008), and Rashidi et al (2008) for different goat breeds.…”

“…Direct heritability for WWT from model 4 was 0.09± 0.03, which was similar to estimates by Notter (1998) for Polypay sheep (0.07), Ekiz et al (2004) for Turkish Merino sheep (0.06), Maroof et al (2005) for Avikalin sheep (0.077) and Boujenane and El Hazzab (2008) for Draa goats, Zhang et al (2009) reported similar estimate (0.09± 0.04) from similar model in Boer goats. Higher estimates than the current study were reported by Schoeman et al (1997) in Boer goats (0.18), Mourad and Anous (1998) in Common African and Alpine crossbred kids (0.49), AlShorepy et al (2002) in Emirati goats (0.34), Roy et al (2008) in Jamunapari goats (0.18), Rashidi et al (2008) in Markhoz goats (0.15), Kantanamalakul et al (2008) in mixed goat population (0.45), and Maghsoudi et al (2009) in Iranian Cashemere goats (0.20).…”

“…Our h 2 estimate for BWT was in accordance with the estimates obtained by using simple animal model (model 1) by Al-Shorepy et al (2002) for Emirati goats (0.30), Rashidi et al (2008) for Markhoz goats (0.35±0.04), Zhang et al (2008) for Boer goats (0.30±0.06), Kantanamalakul et al (2008) for mixed goat population (0.30±0.04) and Zhang et al (2009) for Boer goats (0.30±0.06). Current Estimate is higher than reports by Yalcin et al (1989) and Gerstmayr and Horst (1995) in Angora goats (0.00 and 0.02), Schoeman et al (1997) for Boer goats (0.16), Mugambi et al (2007) in the Kenya dual-purpose goats (0.13), Boujenane and El Hazzab (2008) for Draa goats (0.16), Roy et al (2008) for Jamunapari goats (0.12), Shaat and Maki-Tanila (2009) for Zairabi goats (0.10), and Maghsoudi et al (2009) for Iranian Cashmere goats (0.20). Higher estimate than current study was reported by Mourad and Anous (1998) in common African and Alpine crossbred goats (0.68), Portolano et al (2002) in Sicilian Girgentana goat (0.49), and Bosso et al (2007) in Dwarf goats (0.50).…”

Estimating non-genetic and genetic parameters of pre-weaning growth traits in Raini Cashmere goat

“…Its population is about 2 million heads (Madad 1999). Few studies have reported estimates of genetic parameters for performance traits in this breed (Maghsoudi et al 2009). Therefore, the main objectives of this study were the estimation of genetic and non-genetic parameters for pre-weaning growth traits and Kleiber ratio of Raini kids, fitting different animal models including both individual and maternal effects.…”
