Factors affecting ewe’s milk fat and protein content and relationships between milk yield and milk components
sheep milk composition environmental effects correlations lactation curves
2015/6/4
Test-day records of purebred Tsigai, Improved Valachian and Lacaune ewes were used to analyse the effect of environmental factors on milk fat and protein content. There were 121 424 and 121 158 measur...
