Aim of the current comparative study was to evaluate the production and reproduction efficiency in indigenous Turcana and endangered Ratca sheep breeds. Milk yield for the two breeds was on average 68.23±2.33 kg for Ratca ewes and 76.81±2.99 kg in Turcana, respectively, differences between two breeds were significant (p≤0.01). Conception rates were of 97.7±0.87% in Ratca and of 94.8±0.65% in Turcana ewes, respectively, differences were significant between the two flocks (p≤0.05), with the Ratca ewes achieving better fertility rates, compared to their counterparts, the Turcana breed. For prolificacy, the Turcana ewes outperformed significantly (p≤0.01) the Ratca, with an average litter size of 124.2±1.86% and 110.1±1.44%, respectively. Lambs survival and adult ewe culling rates were not affected by the breed factor (p>0.05). Adult ewes body weight when put to ram was significantly (p≤0.05) influenced by the breed, with Turcana ewes having on average 53.8±2.89 kg, compared to 48.0±3.22 kg for the Ratca ewes. The average farm yearly incomes were estimated to be of 150.32 EUR for Ratca ewe-unit and of 144.97 EUR for the Turcana ewe-unit. Although the Turcana outperformed the Ratca ewes, the annual revenue was higher for the Ratca, due to the state conservation subsidy for rare and endangered breeds. [ABSTRACT FROM AUTHOR] |
