The Bos taitru.v-Bos mucus crossbreeding is the best genetic strategy for dual purpose systems of production in the tropics, so it is very important to compare several breeding groups for every productive trait. The purpose of the work was to
study the growth rate of 10 breed groups in north western Colombia. The calves were
raised under the dual purpose system, which include the permanency of the calves
with their dams for 8 to 9 hours after partial milking of the cows. The data were analyzed by least squares methods and the means were compared by Tukey test. The
analysis of variance revealed that breed group effect were significant for the 5 variables studied. At weaning the Zebu breed with 157.4 kg excelled all other breed
groups with the exception of F1 Normande x Zebu (165.7 kg) and red Holstein x
Zebu (165.5 kg). The Costeño con Cuernos breed had the lightest weaning weight
(127.5 kg). At 18 months the Zebu breed with 249.2 kg was excelled by all the crosses, again the F1 Red Holstein x Zebu (307.5 kg) and the Normande x Zebu (295.9
kg) were the best breed groups. The Costeno con Cuernos breed with 224.6 kg held
the last position. For pre and pos-weaning weight gains it was observed something
similar that at weaning and 18 months. For pre-weaning gain, with the exception of
F1 Normande x Zebu (0.556 kg) and Red Holstein x Zebu (0.553 kg), the Zebu breed
with 0.533 kg excelled all other groups. The Costeño con Cuernos breed (0.407 kg)
had the smallest pre-weaning gain. For pos-weaning gain it was observed that with
the exception of the Costeño con Cuernos (0.314 kg) all other groups excelled the
Zebu breed (0.322 kg). Again the Red Holstein x Zebu (0.456 kg) and the Normande
x Zebu (0.435 kg) were the best. |

El cruzamiento de Bos taurus-Bos indicus es probablemente la mejor estrategia genética para sistemas de doble propósito en condiciones tropicales, por tanto es de interés comparar varios grupos raciales en todas las características productivas. El objetivo del trabajo fue el de estudiar las tasas de crecimiento de 10 grupos raciales en la parte nor-occidental de Colombia. Los terneros fueron criados bajo el sistema de doble propósito o sea que permanecieron con sus madres después del ordeño parcial de ellas. Los datos se analizaron por el mátodo de cuadrados mínimos y los promedios se compararon por la prueba de Tukey. Los análisis de varianza revelaron que el efecto del grupo racial fue significativo para las 5 variables estudiadas. Al destete, el Cebú con un peso de 157.4 kg superó a todos los demás grupos con la excepción de los F1 Normando x Cebú (165.7 kg) y Holstein Rojo x Cebú (165.5 kg). El Costeño con Cuernos tuvo el menor peso corporal (127.5 kg). A los 18 meses, el Cebú con 249.2 kg es superado por todos los grupos de cruzados, siendo de nuevo los F1 Holstein Rojo x Cebú (307.5 kg) y Normando x Cebú (295.9 kg) los mejores grupos raciales. El costeño con Cuernos con 224.6 kg ocupó el último lugar. Para las ganancias pre y posdestete se observó algo similar a lo registrado al destete y 18 meses. Para la ganancia predestete, con la excepción de los F1 Normando x Cebú (0.556 kg) y Hosltein Rojo x Cebú (0.553 kg), el Cebú con 0.533 kg aventajó a todos los grupos. El Costeño con Cuernos (0.407 kg) tuvo la menor ganancia predestete. Para la ganancia posdestete se observó que con la excepción del Costeño con Cuernos (0.314 kg) todos los demás grupos superan al Cebú (0.322 kg). De nuevo se destacaron el Hosltein Rojo x Cebú (0.456 kg) y el Normando x Cebú (0.435 kg) Ganado de doble propósito-Ganaderia doble proposito 2019-09-06T16:49:52Z 2019-09-06T16:49:52Z 1990 article Artículo científico http://purl.org/coar/resource_type/c_2df8fbb1 info:eu-repo/semantics/article https://purl.org/redcol/resource_type/ART http://purl.org/coar/version/c_970fb48d4fbd8a85 0018-8794 http://hdl.handle.net/20.500.12324/35408 17620 reponame:Biblioteca Digital Agropecuaria de Colombia repourl:https://repository.agrosavia.co instname:Corporación colombiana de investigación agropecuaria AGROSAVIA spa Revista ICA 4 307 314 Attribution-NonCommercial-NoDerivatives 4.0 International http://creativecommons.org/licenses/by-nc-nd/4.0/ Acceso a texto completo info:eu-repo/semantics/openAccess application/pdf application/pdf Atlántico C.I Tibaitatá Colombia Instituto Colombiano Agropecuario - ICA Bogotá (Colombia) Revista ICA; Vol. 25, Núm. 4 (1990): Revista ICA (Octubre-Diciembre);p. 307-314 |
