Factores que afectan a la edad al primer parto en el ganado vacuno de raza retinta
(Universidad de Córdoba, Servicio de Publicaciones, 1995)
It is posible to get an increase of reproductive efficiency by decreasing age at first calving. In this study we show the influence of some enviromental factors that affect this parameter in Retinto cattle. 1786 first ...
Estimación de la curva de crecimiento en vacuno retinto desde el nacimiento hasta el destete
(Universidad de Córdoba, Servicio de Publicaciones, 1995)
Several growth equations exist according to different approaches of authors that have studied this matter, but practically all coincide, on analyzing the growth up to mature age, that the curve acquires a sigmoid form; ...
Análisis del flujo de sementales retintos
(Universidad de Córdoba, Servicio de Publicaciones, 1995)
In Retinto Beef cattle breeding, a series of farms have stood out as leaders in animal production in the supply of sires to other farms. In this paper we have made an analysis of these outstanding farms in order to study ...
Paquetes informáticos en la mejora genética del vacuno de carne
(Universidad de Córdoba, Servicio de Publicaciones, 1995)
In the last decades, we have witnessed a growing calculation power of computers and a dramatic cheapening of these. This has permitted development of mathematical models for problem resolution in increasingly complex animal ...
Análisis de los factores que afectan a la curva de crecimiento del ganado vacuno retinto hasta el destete
(Universidad de Córdoba, Servicio de Publicaciones, 1995)
A study was made of the growth of Retinto beef cattle through analysis of factors affecting the characteristic linear growth curve of this breed in its developmental environment. By addressing these factors, growth and ...
Análisis genético de los niveles de consanguinidad en la raza retinta
(Universidad de Córdoba, Servicio de Publicaciones, 1995)
Within the improvement plan, inbreeding crosses may prove to be a tool that the Retinto cattle breeder might use along with selection to increase the genetic merits of his breed. The majority of breeders know the effects ...
Experiencias sobre inseminación artificial en hembras bovinas retintas tras tratamientos estimuladores de celo
(Universidad de Córdoba, Servicio de Publicaciones, 1995)
We have realised artificial insemination oí 877 females of the Retinto cattle breed. Previously we applied three different treatments for estrus stimulation. The first and the second were induction treatments, with Syncro-Mate ...
Análisis crítico del acceso a series de testaje del esquema de selección de la raza retinta
(Universidad de Córdoba, Servicio de Publicaciones, 1995)
This study aims to evaluate the incidence of various requirements that male animals had to meet for their participation in 1995 testing series developed by the National Selection Plan of Retinto Beef Cattle. In a stratified ...
Evolución de la metodología de la mejora genética en el vacuno de carne
(Universidad de Córdoba, Servicio de Publicaciones, 1995)
The evolution of the genetic improvement methodology in the beef cattle has been based, as in other species, in our capacity to detect the best genotypes for using as reproducers. In this paper are described three phases ...
