Protein Requirements of Zebu Beef Cattle
Protein is one of the most important essential nutrients; it is involved in many vital functions in the body, such as growth and tissue repair, enzyme catalysis, transport and storage, coordinated movement, mechanical support, immunological protection, generation and transmission of nerve impulses, and control of metabolism, growth and cellular differentiation. Therefore, ensure adequate supply...
متن کاملRelationships of growth hormone gene and milk protein polymorphisms to milk production traits in Simmental cattle.
The importance of milk proteins and the positive effect of administration of growth hormone (GH) on milk production, and the presence in some dairy cattle lines of greater GH concentrations prompted us to examine the presence of restriction fragment length polymorphism at the GH gene using the restriction enzyme TaqI and to investigate associations between this polymorphism in Simmental cows an...
متن کاملPedigree analysis in the Brazilian Zebu breeds.
Zebu breeds play an important role in cattle production systems in Brazil. To assess the genetic variability from animals in the Herd Books of Nelore, Gir and Guzerat breeds, generation intervals, inbreeding, effective population size and parameters of gene origin (effective number of founders, ancestors and founder genomes) were calculated using pedigree records from 1938 to 1998. Breed subdiv...
متن کاملInbreeding depression in Zebu cattle traits.
The productivity of herds may be negatively affected by inbreeding depression, and it is important to know how intense is this effect on the livestock performance. We performed a comprehensive analysis involving five Zebu breeds reared in Brazil to estimate inbreeding depression in productive and reproductive traits. Inbreeding depression was estimated for 13 traits by including the individual ...
متن کاملInvited review: milk protein polymorphisms in cattle: effect on animal breeding and human nutrition.
The 6 main milk proteins in cattle are encoded by highly polymorphic genes characterized by several nonsynonymous and synonymous mutations, with up to 47 protein variants identified. Such an extensive variation was used for linkage analysis with the description of the casein cluster more than 30 yr ago and has been applied to animal breeding for several years. Casein haplotype effects on produc...
