The goal of this study was to investigate the udder cistern size using ultrasound technique in purebred Improved Valachian (IV), Tsigai (T), Lacaune (LC) ewes, and their crosses with specialized dairy breeds Lacaune (LC) and East Friesian (EF).
Purebred Improved Valachian (IV), purebred Tsigai (T) and purebred Lacaune (LC) ewes, and IV and T crosses with 25%, 50 and 75% genetic proportion of specialized dairy breeds (SDB) Lacaune and East Friesian were included in this seven year long experiment experiment (IVxSDB 25%; IVxSDB 50%; IVxSDB75 %; TxSDB25 %; TxSDB 50%; TxSDB 75%).
Comparison of external udder measurements of the sheep breeds Improved Valachian, Tsigai, Lacaune and their crosses.
Ten minutes from the city, you can see what Ostrava looked like before the industrial revolution, at the Valachian
2006) constataram maior producao de leite para as ovelhas Lacaune, quando avaliaram curvas de producao de tres racas distintas (Tsigai, Improved Valachian
Broucek to the Moon, The Makropulos Case and From the House of the Dead, as well as the stage performance of the Valachian
2009), which involved a mixed population of 96 sheep of Tsigai, Improved Valachian
, East Friesian, Lacaune and Lacaune x Tsigai breeds, cumulative observed frequencies of 87%, 13% and 0% were found for the MM, MN and NN genotypes respectively.
The most widespread dairy breeds in Slovakia are Improved Valachian and Tsigai.
The complexes of milk production, meat production, functional and wool traits took a share of 27%, 9%, 63% and 1%, respectively, in Improved Valachian and 33%, 7%, 59% and 1%, respectively, in the Tsigai breed in the sum of the absolute values of the standardized economic values.
ABSTRACT : Data from milk performance testing were used to analyze genetic and environmental trends for purebred Tsigai, Improved Valachian and Lacaune sheep.
The aim of our work was to estimate genetic and environmental trends for milk yield, fat and protein content in Slovakian purebred sheep populations of Tsigai, Improved Valachian and Lacaune breeds using the animal model based on test-day measurements which was introduced in Slovakia recently (Oravcova et al.
