Ruminantlarda Beslenmenin Süt Verimi ve Kalitesi Üzerine Etkisi

Öz

Süt sığırcılığında başarı, maliyet hesaplamaları göz önünde bulundurularak en iyi rasyonla en yüksek süt verimini elde edebilmektir. Süt verimi temelde, beslenme dışı ve beslenmeye bağlı faktörler olmak üzere iki başlıkta ele alınabilir. Bu amaçla; beslenme dışı (genotip, laktasyon, barındırma, sağım uygulamaları, yaş ve cüsse, kuruda kalma süresi, kızgınlık ve gebelik, ikizlik, çevre, buzağılama mevsimi, gün ışığı, egzersiz, ilaçlama, hormonlar) ve beslenmeye bağlı (besleme aralığı, karbonhidratlar, yağlar, proteinler, somatik hücre sayısı, vitaminler, mineraller, su ve yem katkı maddeleri) faktörler irdelenmiştir. Beslenmeye bağlı protein, laktoz, su, mineraller ve yağlar gibi birçok faktör süt kompozisyonunu etkiler. Süt bileşenlerinden en çok yağ ve protein rasyon değişikliklerinden etkilenmektedir. Diğer süt bileşenleri, laktoz ve mineraller rasyon değişikliklerinden çok fazla etkilenmezler. Yetiştiricilikte hastalıkların %80’inin beslenmeye bağlı olduğu ve en iyi verimi elde etmede beslenmenin ne kadar önemli olduğu düşünüldüğünde beslenmeye gereken özenin gösterilmesi büyük önem taşımaktadır. Bu çalışmada; ruminantlarda beslenmeye bağlı faktörlerin süt kompozisyonu ve verimi üzerindeki etkileri derlenmiştir.

The Effect of Nutrition on Milk Yield and Quality in Ruminants

Öz

Success in dairy cattle breeding is to obtain the highest milk yield with the best ration, taking into account cost calculations. Milk yield can be basically discussed under two headings as non-nutritive and nutrition-related factors. To this end; non-nutritional (genotype, lactation, housing, milking practices, age and size, drying time, heat and pregnancy, twins, environment, calving season, daylight, exercise, spraying, hormones, feeding interval) and nutritional (carbohydrates, fats, proteins, somatic cell number, vitamins, minerals, water and feed additives) factors were examined. Many factors such as dietary protein, lactose, water, minerals and fats affect milk composition. Milk components are mostly affected by fat and protein ration changes. Other milk components, lactose and minerals are not much affected by ration changes. Considering that 80% of diseases in aquaculture depend on nutrition and how important nutrition is in obtaining the best efficiency, it is of great importance to pay attention to nutrition. In this study; The effects of nutritional factors on milk composition and yield in ruminants were compiled.
