Investigation of genotype x environment interactions for weaning weight for Herefords in three countriesD de Mattos J K Bertrand and I MisztalJournal of animal science 2000 78 8 2121-2126doi20007882121x2000

Variance and covariance components for weaning weight for Herefords in three countriesD de Mattos I Misztal and J K BertrandJournal of animal science 2000 78 1 33-37doi200078133x2000

Direct and maternal (in parentheses) estimated genetic correlations for CA vs UY CA vs US US vs UY UP-CB vs S-GC UP vs CB and S vs GC were 88 (84) 86 (82) 90 (85) 88 (87) 88 (84) and 87 (85) respectively The general absence of genotype x country interactions observed in this study together with a prior study that showed the similarity of genetic and environmental parameters across the three countries strongly indicates that a joint WWT genetic evaluation for Hereford cattle could be conducted using a model that treated the information from CA UY and US as a single population using single population-wide genetic parameters

Abstract

ESPASANDIN Ana Carolina URIOSTE Jorge Ignacio CAMPOS Leonardo Talavera and ALENCAR Mauriacutecio Mello de Genotype times country interaction forweaning weight in the Angus populations of Brazil and Uruguay R Bras Zootec [online] 2011 vol40 n3 pp 568-574 ISSN 1806-9290 httpdxdoiorg101590S1516-35982011000300014

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed

Investigation of genotype x environment interactions for weaning weight for Herefords in three countriesD de Mattos J K Bertrand and I MisztalJournal of animal science 2000 78 8 2121-2126doi20007882121x2000

Variance and covariance components for weaning weight for Herefords in three countriesD de Mattos I Misztal and J K BertrandJournal of animal science 2000 78 1 33-37doi200078133x2000

Direct and maternal (in parentheses) estimated genetic correlations for CA vs UY CA vs US US vs UY UP-CB vs S-GC UP vs CB and S vs GC were 88 (84) 86 (82) 90 (85) 88 (87) 88 (84) and 87 (85) respectively The general absence of genotype x country interactions observed in this study together with a prior study that showed the similarity of genetic and environmental parameters across the three countries strongly indicates that a joint WWT genetic evaluation for Hereford cattle could be conducted using a model that treated the information from CA UY and US as a single population using single population-wide genetic parameters

Abstract

ESPASANDIN Ana Carolina URIOSTE Jorge Ignacio CAMPOS Leonardo Talavera and ALENCAR Mauriacutecio Mello de Genotype times country interaction forweaning weight in the Angus populations of Brazil and Uruguay R Bras Zootec [online] 2011 vol40 n3 pp 568-574 ISSN 1806-9290 httpdxdoiorg101590S1516-35982011000300014

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed

Investigation of genotype x environment interactions for weaning weight for Herefords in three countriesD de Mattos J K Bertrand and I MisztalJournal of animal science 2000 78 8 2121-2126doi20007882121x2000

Variance and covariance components for weaning weight for Herefords in three countriesD de Mattos I Misztal and J K BertrandJournal of animal science 2000 78 1 33-37doi200078133x2000

Direct and maternal (in parentheses) estimated genetic correlations for CA vs UY CA vs US US vs UY UP-CB vs S-GC UP vs CB and S vs GC were 88 (84) 86 (82) 90 (85) 88 (87) 88 (84) and 87 (85) respectively The general absence of genotype x country interactions observed in this study together with a prior study that showed the similarity of genetic and environmental parameters across the three countries strongly indicates that a joint WWT genetic evaluation for Hereford cattle could be conducted using a model that treated the information from CA UY and US as a single population using single population-wide genetic parameters

Abstract

ESPASANDIN Ana Carolina URIOSTE Jorge Ignacio CAMPOS Leonardo Talavera and ALENCAR Mauriacutecio Mello de Genotype times country interaction forweaning weight in the Angus populations of Brazil and Uruguay R Bras Zootec [online] 2011 vol40 n3 pp 568-574 ISSN 1806-9290 httpdxdoiorg101590S1516-35982011000300014

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed

Investigation of genotype x environment interactions for weaning weight for Herefords in three countriesD de Mattos J K Bertrand and I MisztalJournal of animal science 2000 78 8 2121-2126doi20007882121x2000

Variance and covariance components for weaning weight for Herefords in three countriesD de Mattos I Misztal and J K BertrandJournal of animal science 2000 78 1 33-37doi200078133x2000

Direct and maternal (in parentheses) estimated genetic correlations for CA vs UY CA vs US US vs UY UP-CB vs S-GC UP vs CB and S vs GC were 88 (84) 86 (82) 90 (85) 88 (87) 88 (84) and 87 (85) respectively The general absence of genotype x country interactions observed in this study together with a prior study that showed the similarity of genetic and environmental parameters across the three countries strongly indicates that a joint WWT genetic evaluation for Hereford cattle could be conducted using a model that treated the information from CA UY and US as a single population using single population-wide genetic parameters

Abstract

ESPASANDIN Ana Carolina URIOSTE Jorge Ignacio CAMPOS Leonardo Talavera and ALENCAR Mauriacutecio Mello de Genotype times country interaction forweaning weight in the Angus populations of Brazil and Uruguay R Bras Zootec [online] 2011 vol40 n3 pp 568-574 ISSN 1806-9290 httpdxdoiorg101590S1516-35982011000300014

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed

Investigation of genotype x environment interactions for weaning weight for Herefords in three countriesD de Mattos J K Bertrand and I MisztalJournal of animal science 2000 78 8 2121-2126doi20007882121x2000

Variance and covariance components for weaning weight for Herefords in three countriesD de Mattos I Misztal and J K BertrandJournal of animal science 2000 78 1 33-37doi200078133x2000

Direct and maternal (in parentheses) estimated genetic correlations for CA vs UY CA vs US US vs UY UP-CB vs S-GC UP vs CB and S vs GC were 88 (84) 86 (82) 90 (85) 88 (87) 88 (84) and 87 (85) respectively The general absence of genotype x country interactions observed in this study together with a prior study that showed the similarity of genetic and environmental parameters across the three countries strongly indicates that a joint WWT genetic evaluation for Hereford cattle could be conducted using a model that treated the information from CA UY and US as a single population using single population-wide genetic parameters

Abstract

ESPASANDIN Ana Carolina URIOSTE Jorge Ignacio CAMPOS Leonardo Talavera and ALENCAR Mauriacutecio Mello de Genotype times country interaction forweaning weight in the Angus populations of Brazil and Uruguay R Bras Zootec [online] 2011 vol40 n3 pp 568-574 ISSN 1806-9290 httpdxdoiorg101590S1516-35982011000300014

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed

During grazing genotyped groups differed in DMI (P = 0005) inMEI (P = 0006) and in RFIK (P = 0002) but did not differ in ADGand FCR Our results demonstrate a strong association betweenthese 3 SNP and RFI when animals were grazing on a high-quality high-availability pasture whereas a weak effect wasobserved under confinement

Investigation of genotype x environment interactions for weaning weight for Herefords in three countriesD de Mattos J K Bertrand and I MisztalJournal of animal science 2000 78 8 2121-2126doi20007882121x2000

Variance and covariance components for weaning weight for Herefords in three countriesD de Mattos I Misztal and J K BertrandJournal of animal science 2000 78 1 33-37doi200078133x2000

Direct and maternal (in parentheses) estimated genetic correlations for CA vs UY CA vs US US vs UY UP-CB vs S-GC UP vs CB and S vs GC were 88 (84) 86 (82) 90 (85) 88 (87) 88 (84) and 87 (85) respectively The general absence of genotype x country interactions observed in this study together with a prior study that showed the similarity of genetic and environmental parameters across the three countries strongly indicates that a joint WWT genetic evaluation for Hereford cattle could be conducted using a model that treated the information from CA UY and US as a single population using single population-wide genetic parameters

Abstract

ESPASANDIN Ana Carolina URIOSTE Jorge Ignacio CAMPOS Leonardo Talavera and ALENCAR Mauriacutecio Mello de Genotype times country interaction forweaning weight in the Angus populations of Brazil and Uruguay R Bras Zootec [online] 2011 vol40 n3 pp 568-574 ISSN 1806-9290 httpdxdoiorg101590S1516-35982011000300014

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed

During grazing genotyped groups differed in DMI (P = 0005) inMEI (P = 0006) and in RFIK (P = 0002) but did not differ in ADGand FCR Our results demonstrate a strong association betweenthese 3 SNP and RFI when animals were grazing on a high-quality high-availability pasture whereas a weak effect wasobserved under confinement

Abstract

ESPASANDIN Ana Carolina URIOSTE Jorge Ignacio CAMPOS Leonardo Talavera and ALENCAR Mauriacutecio Mello de Genotype times country interaction forweaning weight in the Angus populations of Brazil and Uruguay R Bras Zootec [online] 2011 vol40 n3 pp 568-574 ISSN 1806-9290 httpdxdoiorg101590S1516-35982011000300014

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed

Direct and maternal (in parentheses) estimated genetic correlations for CA vs UY CA vs US US vs UY UP-CB vs S-GC UP vs CB and S vs GC were 88 (84) 86 (82) 90 (85) 88 (87) 88 (84) and 87 (85) respectively The general absence of genotype x country interactions observed in this study together with a prior study that showed the similarity of genetic and environmental parameters across the three countries strongly indicates that a joint WWT genetic evaluation for Hereford cattle could be conducted using a model that treated the information from CA UY and US as a single population using single population-wide genetic parameters

Abstract

ESPASANDIN Ana Carolina URIOSTE Jorge Ignacio CAMPOS Leonardo Talavera and ALENCAR Mauriacutecio Mello de Genotype times country interaction forweaning weight in the Angus populations of Brazil and Uruguay R Bras Zootec [online] 2011 vol40 n3 pp 568-574 ISSN 1806-9290 httpdxdoiorg101590S1516-35982011000300014

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed

Direct and maternal (in parentheses) estimated genetic correlations for CA vs UY CA vs US US vs UY UP-CB vs S-GC UP vs CB and S vs GC were 88 (84) 86 (82) 90 (85) 88 (87) 88 (84) and 87 (85) respectively The general absence of genotype x country interactions observed in this study together with a prior study that showed the similarity of genetic and environmental parameters across the three countries strongly indicates that a joint WWT genetic evaluation for Hereford cattle could be conducted using a model that treated the information from CA UY and US as a single population using single population-wide genetic parameters

Abstract

ESPASANDIN Ana Carolina URIOSTE Jorge Ignacio CAMPOS Leonardo Talavera and ALENCAR Mauriacutecio Mello de Genotype times country interaction forweaning weight in the Angus populations of Brazil and Uruguay R Bras Zootec [online] 2011 vol40 n3 pp 568-574 ISSN 1806-9290 httpdxdoiorg101590S1516-35982011000300014

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed

During grazing genotyped groups differed in DMI (P = 0005) inMEI (P = 0006) and in RFIK (P = 0002) but did not differ in ADGand FCR Our results demonstrate a strong association betweenthese 3 SNP and RFI when animals were grazing on a high-quality high-availability pasture whereas a weak effect wasobserved under confinement

ESPASANDIN Ana Carolina URIOSTE Jorge Ignacio CAMPOS Leonardo Talavera and ALENCAR Mauriacutecio Mello de Genotype times country interaction forweaning weight in the Angus populations of Brazil and Uruguay R Bras Zootec [online] 2011 vol40 n3 pp 568-574 ISSN 1806-9290 httpdxdoiorg101590S1516-35982011000300014

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed

Abstract

ESPASANDIN Ana Carolina URIOSTE Jorge Ignacio CAMPOS Leonardo Talavera and ALENCAR Mauriacutecio Mello de Genotype times country interaction forweaning weight in the Angus populations of Brazil and Uruguay R Bras Zootec [online] 2011 vol40 n3 pp 568-574 ISSN 1806-9290 httpdxdoiorg101590S1516-35982011000300014

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed

ESPASANDIN Ana Carolina URIOSTE Jorge Ignacio CAMPOS Leonardo Talavera and ALENCAR Mauriacutecio Mello de Genotype times country interaction forweaning weight in the Angus populations of Brazil and Uruguay R Bras Zootec [online] 2011 vol40 n3 pp 568-574 ISSN 1806-9290 httpdxdoiorg101590S1516-35982011000300014

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed

Abstract

ESPASANDIN Ana Carolina URIOSTE Jorge Ignacio CAMPOS Leonardo Talavera and ALENCAR Mauriacutecio Mello de Genotype times country interaction forweaning weight in the Angus populations of Brazil and Uruguay R Bras Zootec [online] 2011 vol40 n3 pp 568-574 ISSN 1806-9290 httpdxdoiorg101590S1516-35982011000300014

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed

Direct and maternal (in parentheses) estimated genetic correlations for CA vs UY CA vs US US vs UY UP-CB vs S-GC UP vs CB and S vs GC were 88 (84) 86 (82) 90 (85) 88 (87) 88 (84) and 87 (85) respectively The general absence of genotype x country interactions observed in this study together with a prior study that showed the similarity of genetic and environmental parameters across the three countries strongly indicates that a joint WWT genetic evaluation for Hereford cattle could be conducted using a model that treated the information from CA UY and US as a single population using single population-wide genetic parameters

Abstract

ESPASANDIN Ana Carolina URIOSTE Jorge Ignacio CAMPOS Leonardo Talavera and ALENCAR Mauriacutecio Mello de Genotype times country interaction forweaning weight in the Angus populations of Brazil and Uruguay R Bras Zootec [online] 2011 vol40 n3 pp 568-574 ISSN 1806-9290 httpdxdoiorg101590S1516-35982011000300014

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed

Direct and maternal (in parentheses) estimated genetic correlations for CA vs UY CA vs US US vs UY UP-CB vs S-GC UP vs CB and S vs GC were 88 (84) 86 (82) 90 (85) 88 (87) 88 (84) and 87 (85) respectively The general absence of genotype x country interactions observed in this study together with a prior study that showed the similarity of genetic and environmental parameters across the three countries strongly indicates that a joint WWT genetic evaluation for Hereford cattle could be conducted using a model that treated the information from CA UY and US as a single population using single population-wide genetic parameters

ESPASANDIN Ana Carolina URIOSTE Jorge Ignacio CAMPOS Leonardo Talavera and ALENCAR Mauriacutecio Mello de Genotype times country interaction forweaning weight in the Angus populations of Brazil and Uruguay R Bras Zootec [online] 2011 vol40 n3 pp 568-574 ISSN 1806-9290 httpdxdoiorg101590S1516-35982011000300014

Coeficients of correlation among maternal and direct genetic effects between Brazil and Uruguay were 077 and 013 respectively

he results suggest the existence of genotype times environment interaction for weight at weaning of Angus populations between Brazil and Uruguay There is a need of considering interaction in further international genetic evaluations of the breed
