Donör ineklerin beslenmesi

Donör ineklerin beslenmesinde başarı, elde edilen toplam oosit ve transfer edilebilen embriyo sayısına bağlıdır. Donör ineklerin iyi bir şekilde beslenmesi için ırk, yaş, canlı ağırlık, laktasyon sayısı, süt verimi, vücut kondüsyon skoru ve önceki beslenme programları dikkate alınmalıdır. Yüksek süt veren laktasyondaki donör inekler süt ve süt bileşenlerinin sentezi için önemli miktarda besin maddelerine ihtiyaçları vardır. Bu ihtiyaçların yanı sıra donör ineklerin yeterli ve kaliteli oosit ve embriyo üretimi için de yüksek besin maddelerine gereksinimleri bulunmaktadır. Rasyonda özellikle enerji, ham protein, karbonhidrat, vitamin ve mineral madde düzeyleri yeterli olmalıdır. Donör inekler embriyo toplama periyodunda her türlü stres faktörlerinden uzak tutulmalıdır. Bu derlemede donör ineklerin beslenmesi gözden geçirilmiş ve bununla ilişkili bileşenler üzerinde durulmuştur.

Nutrition of donor cows

Success of feeding donor cows depend on total oocyte and tranferable oocyte numbers. Breed, age, live weight, lactation number, milk yield, body condition and previous feeding program should be considered to achive good donor cow’s nutrition. High yielding cows need substantial amount of nutrients for milk and milk components synthesis. Besides these needs, the donor cows had also high nutrient requirements for enough and high quality oocyte and embryos. Ration especially energy, crude protein, carbohydrate, vitamin and mineral levels should be sufficient. Donor cows should not suffer any stress factor during embryo collection periods as well. In this paper, nutrition of the donor cows have been reviewed and the associated with components are emphasized.
