Bovino West Highland by turdusprosopis. The mean absolute age difference among the cohort was 36 d and the mean range was 83 d. An overview of the Brazilian dairy industry is presented here and further background is given in the Appendix. Albeit based on small numbers of animals, the results Table 10 were in line with the international literature references in Teodoro and Madalena a,b. There is also interest in the region as to whether dairy bulls should be selected specifically for the various ecological zones.
Farmers regulate the amount of milk produced by altering the amount of concentrates fed, by milking only once a day lechedo part or the whole herd leaving more milk for the calves, or by switching to a total suckling system Madalena a.
Moreover their data were not appropriated for comparisons between crosses due to grouping together different European breeds, grouping different zebu breeds, confounding of breeds, crosses and farms and editing out short lactations and long calving intervals. Los hijos de estos fueron posteriormente arreados por Garay en ypara las fundaciones de Santa Fe y Huzerat Aires. A comparison within production systems would provide a clearer evaluation of the genetic group differences.
So the extra milk sold economically justified the first system. Nelsen et alwhich may influence the nutrition cost because of the lower maintenance energy requirements for fat than for other tissues e.

The same would apply to the recurrent use of F 1 bulls proposed by Hickman Genetic evaluation includes both purebreds and crossbreds and the B. This result applies to the bucket machine-milking parlour and calf huts in that experiment and may not extrapolate to other facilities.
The milk suckled from the F 1 by the male calves was not accounted for and probably would mean that the F1 produced similar or higher milk yield than other crosses. Milk production tripled between lwcherofrom Braford bovineBraford cattleBraford cow The bulls belong to the individual breeders and AI companies contract semen production with them.
