Abstract

Su, en küçük
canlıdan en büyüğüne kadar tüm canlıların biyolojik yaşamları ve faaliyetleri
için gerekli olan en temel besin maddesidir. Fakat, canlılar için hayati öneme
sahip olan ve dünya yüzeyinin dörtte üçünü kaplayan su varlığının sadece %1’den
daha az miktarı, ekosistem ve insan kullanımına elverişli tatlı su kaynaklarını
oluşturmaktadır. Bu durum, yakın gelecekte artan insan nufusunun beslenmesi ve
suya erişimi konusunda endişelere sebep olmaktadır. Ayrıca, özellikle insan ve
hayvanların beslenmesinde ortak kullanılan yem hammaddeleri ve suyun tüketimi
üzerine bir rekabet olacağı düşünülmektedir. Bu durumda, hayvancılıkta
sürdürülebilir yapıyı sağlama noktasında dünya üzerinde kısıtlı olarak bulunan
ekosistem ve insan kullanımına elverişli tatlı su kaynaklarının miktar ve
kalitesinin yetersiz kalması beklentisine karşı su kullanım etkinliğinin
arttırılması gerekmektedir. Bu nedenle hayvansal üretimde zor koşullara
dayanıklı olmaları ve bu koşullarda verimliliklerini devam ettirebildikleri
için özellikle küçükbaş hayvanların gelecekte önem kazanacağı düşünülmektedir. Mevcut çalışmanın amacı, nufusun artması ile birlikte yakın
gelecekte gerçekleşmesi beklenen kısıtlı su olanaklarının sıcak koşullar
altında yetiştirilen küçükbaş hayvanlar üzerindeki etkilerinin
ortaya konulmasıdır.

The Effects of Limited Water Application in Small Ruminants Breeding Under Thermal Stress

Abstract

Water is the
most basic nutrient required for the biological life and activities of all
livings things from the smallest to the largest. However, only less than 1% of
water existence, which is vital to living things and covers three-quarters of
the Earth's surface constitutes freshwater resources conducive to ecosystem and
human use. This condition is causing concerns about the nutrition and access to
water of the increasing human population in the near future. In addition to, it
is thought that there will be a competition on feed raw materials and water
consumption, which are used jointly in nutrition of human and animals
especially. In this case, in order to provide a sustainable structure in animal
husbandry, efficiency of water use should be increased against expectation that
the amount and quality of freshwater resources suitable for human use and
ecosystem will insufficient. For this reason, it is thought that will gain
importance in the future, especially due to small ruminants are resistant to
difficult conditions and can maintain their productivity in these conditions. The
aim of the present study is to reveal of the effects on small ruminants
breeding under hot conditions of limited water opportunities, which are
expected to occur in the near future with the increase of population.
