Özet:

This study is aimed at studying the impact of the breed on sustainability in dairy livestock. For this purpose, one of the criteria of sustainability, cultural energy input output analysis was made. In the study, a full-year data from 24 farms specializing in milk livestock in Burdur, Isparta, Konya, İzmir, Afyonkarahisar, Aksaray and Kırşehir has been collected to cover the dates of October 2017 to September 2018. In the framework of the study, the farms that cultivate the Black Alaca and Simental species, which are most distributed among the cattle races in Turkey, have been selected and the animals here have been used as the work material. As a result of the criteria observed when choosing farms, 10 farms that only cultivate Black Alaca breeds, 7 farms that only cultivate Simental breeds and 7 farms that cultivate two varieties mixed (60% Black Alaca 40% Simental) were included in the project. During the visit to the farms, the monthly supply of cows, milk production, ratio quantity, ratio raw materials, electricity consumption, water consumption, mazot consumption, element number and working hours, food consumption quantities, milk oil, milk protein and lactose values from the monthly milk analysis were recorded. The cultural energy spent for the consumption of food was found by the consumption of the food of the beef and the amount of each content that forms the ratio with the cultural energy value in literature. Transportation energy is also involved in calculations. The total spending of cultural energy was similar to the Black Eagle and mixed farms and was found higher than the Simental farms (P<0.05). The cultural energy spent on the consumed food consists of more than half of the total consumed cultural energy and is similar to the race. The energy consumption efficiency for protein with the cultural energy spent for kilograms of milk is similar to the cemental and mixed farms and is higher than the Black Alaca race (P<0.05). The energy use efficiency was found for the best Black Alaca breed (P<0.05) and the semental and mixed farms had similar efficiency value. As a result, there have been differences between races in terms of the efficiency of cultural energy use and it is important to take into account the efficiency of cultural energy use in terms of sustainability.
