Sardinian sheep milk yield, a study aims to increase it

Is there some way to increase dairy properties and, therefore, the yield of sheep milk obtained from Sardinian sheep, based on good genetics and also thanks to the development of innovative techniques for predicting lactation periods? It looks like the answer is yes.

A project led by Nicola Macciotta of the Department of Agriculture Sciences of the Univeristy of Sassari, in collaboration with the Regional Farmers Association, Assonapa and Apa, aims to do just that. The project has been presented a few days ago in Milan during the seminary promoted by the Italian Farmers Association on “New analytic technologies and innovative instruments for consultancy”; Stefano Sanna and Marino Contu, president and vice-president of Aras respectively, also took part in the seminary.

Increase in sheep milk yield: the project in-depth

The Sampling campaign, as Macciotta explains, has been conducted on 1200 of Sardinian sheep registered in the genealogic book, distributed over 50 breeding farms located all over the region and it involved the sampling of biologic material, through sinus tampons and individual milk samples. Analysis of data obtained from determination of lactodinamographic parameters, with the help of Formagraph and the determination of individual yield, by means of micro cheese-making procedures, highlighted a good genetic variability with a possibility to increase it by selective breeding.

The study – as Marino Contu states, allowed to develop innovative methods to obtain forecast indexes that can be used in routine analyses to identify milk’s predisposition to cheese-making at no additional costs for genetics selection programs.

Sardinian breeding system is at the cutting edge in terms of technology and innovation – says Stefano Sanna. This is also possible thanks to synergies that are being carried out for years with the Academic and research world. Our technicians are the glue connecting these realities and they put new studies into practice every day in the breeding farms.
