Abstract: Comparative studies were carried out on the fattening of the lambs from the Sharri and Kosova strains of sheep raised in a traditional way, which is still practiced in Kosova today. To examine the weight, 24 lambs of each strain (Sharri and Kosova) were taken and were reared in the traditional way for up to 100 days.
The dynamics of the body mass of the lambs was monitored every 10 days. The average birth weight of the lambs from the Sharri breed is 4.156 kg and for the Kosova breed 3.558 kg. The lambs from both strains have doubled the male yeast on the 20th day, when the Sharri strain of lambs have a live weight of 8.381 kg, and the Kosova strain has a live weight of 7.637 kg. The lambs are with their mothers until the 40th day and are fed with meadow hay and ground corn. On the 40th day, the lambs from the Sharri strain had achieved a dry weight of 11.116 kg, while those from the Kosovar strain reached 10.593 kg.
The lambs from the 40th day to the 100th day are separated from their mothers during the day and are fed with meadow hay and ground corn, the sheep crawl at night and then the lambs are let loose and stay overnight with their mothers until the 100th day. On the 100th day when they were slaughtered, the lambs of the Sharri strain achieved a live weight of 24.903 kg and the Kosova strain of 23.191 kg. The slaughter rate of lambs from the Sharri strain is 52.06% and for the Kosova strain 49.02%. The share of muscle tissue in the mass of the carcass in the Sharri strain is 56.586%, fat tissue with 19.914% and bone tissue with 23.631%, in the Kosova strain, muscle tissue is represented by 55.384%, fat by 18.752% and bone by 26.586%.
The average daily growth rates obtained is a result of the breed and the diet.
