Abstract

Important climatic factors, temperature and humidity, are acting complexly and cumulatively on the sheep body, on fodder crops and pastures, in terms of quantity and quality production. The research in this paper aims at the influence of the climatic conditions on the Palas Merino sheep breed and on the Dairy Palas sheep breed productivity. The experiments were conducted at the Palas Research Institute for Sheep and Goat Breeding Constanta. From the thermal point of view, the annual average temperature over the ten years studied was between 11°C and 4°C, which shows the studied area is one of the hottest in the country. Humidity acts in close contact with temperature. From one year to another the milk production in the two sheep breeds had variations and was significantly influenced by climate variability and particularly by the occurrence of climate events. In 2014, the highest milk production was obtained in the Palas Merino breed: total milk production 97.46 ± 2.54 liters, 42.66 liters of milked milk in 92.8 days of lactation, with 5.79±0.10% protein and 6.32±0.14% milk fat. In the Dairy Palas breed: total milk production 227.46±2.54 liters, 142.66 liters of milked milk in 232 days of lactation, with 5.89±0.10% protein and 6.12 ± 0.14% fat.

Key words: climatic, condition, influence, milk, production.
