Abstract
The purpose of the investigations was to analyze the performance of sheep milk production from crossing F1 hybrid of a local sheep with Awassi rams. Milk production control was done after EU methodology, using the A4 control method. After we centralize and analyse the statistical data was evident superior productive hybrid population comparison to maternal race. Thus, while the group consisting of female Tigaie was a daily average production of 0.779 litres per lactation, the F1 hybrid females achieved higher average daily production by 30.01%, or 1.013 litres / capita / day and the total lactation. Evaluation of data resulting from the checks carried out reveal that the Awassi breed positive improves milk production to the race pans. It had also been found that maximum milk production was recorded in the second month of lactation, the average monthly production was 1.300 litres/capita/day in experimental group and 0.950 litres/capita/day in control group. To limit the influence of various factors indicated that both groups throughout the control received the same conditions of maintenance and nutrition. This study highlights the potential of higher production recorded in F1 hybrid population resulting from crossing local sheep with Awassi rams bred Tigaie.
