"Mirandesa" cattle breed: farm structure, management and marketing IPB - Escola Superior Agrária
Fragata, António; Sousa, Fernando Ruivo de.
In spite pof losses suffered in the last decades, the "Mirandesa" cattle breed still plays an important economic and social role and the carcass is famous for the quality of the "posta mirandesa", a very appreciated dish by the rich gastronomy of Portugal. The area studied is the highlands of Northeast of Portugal (Trás-os-Montes) which range from 700 to 1000 metres. The farming systems adopted by farmers are very low intensity animal production systems and the meat of the "Mirandesa" cattle breed has benn marketed as PDO since 1996, within the meaning of the EU rules adopted under the reform of the CAP. This paper reveals the results of soft systems approach to the farmers of the "Professional Association of Mirandesa Breed" which present a diversity of...

"Mirandês" cattle breed: systems and practices of the farmers IPB - Escola Superior Agrária
Fragata, António; Sousa, Fernando Ruivo de.
Over the centuries, the mirandesa breed has been very useful! as traction animal and meat production. The latter, and in relation to other national breeds, their productive capacity occupies the first position and is famous for the quality of "posta mirandesa", a very special and appreciated dish by the rich gastronomy in the Northeast of Portugal. In spite of erosion suffered in the last decades, the ''mirandês'' cattle breed still has an important economic and social value.

Genetic parameters for milk yield and reproduction traits in the Chilean Dairy Overo Colorado cattle breed Ciencia e Investigación Agraria
Montaldo,Hugo H; Trejo,Carlos; Lizana,Carlos.
The objective of this study was to estimate genetic parameters for milk production and reproduction traits using phenotypic and pedigree information from the Dairy Overo Colorado breed from southern Chile. Single- and multi-trait mixed models were used to analyze the data. Analyses were performed using ASReml software. The heritability estimates for milk yield, fat yield, protein yield, fat content, protein content, age at first calving and calving interval were 0.29 ± 0.04, 0.34 ± 0.04, 0.30 ± 0.04, 0.56 ± 0.04, 0.56 ± 0.04, 0.01 ± 0.07 and 0.002 ± 0.02, respectively. The genetic correlations between yield traits were high and positive (≥ 0.81). The genetic correlations of milk yield with fat content (-0.32) and protein content (-0.34) were...

Mirandês cattle breed: genetic and breed improvement IPB - Escola Superior Agrária
Sousa, Fernando Ruivo de; Fragata, António.
The "mirandês cattle breed has had a herd book since 1913 and the agricultural service has implemented a programme of genetic improvemment since the 70's. However, in spite of what has been expected, positive results weren't found on that programme and the "mirandês" cattle breed has gone into a decline. This paper analyses the strategies of several cattle breeder types and the genetic demographic structure of cattle within a community in northeast of Portugal.The present organization of the breed improvement, centered on cattle breeders of pure breed and on farms whith a great number of cows, does not permit genetic improvement. The alternative to the present situation consists of expanding the selection basis, integrating a conceptual level with all...
