The Use of Sweet Potato (Ipomoea batatas) Leaves in Animal Nutrition

Öz

The residual green parts (leave and stem) of the sweet potato, which is an important industrial plant boht for it’s nutritional features and human health, are forage materials that can be used in feeding animals, which is rich with protein, minerals, vitamins and carotenoids. They are also high in amino acid score. Sweet potato leaves (SPL) constitute about 50% of the 6-8 ton/da in a year square meters of green parts, can be used in feeding different species of animals as fresh, silage and dried forms. In fact, in broilers, ruminants, pigs and fishes have shown that the supplementary use of dried SPL as a rational protein source, is increasing the feed intake and body weight gain in animals and does not negatively effect profit of feeds. But, lysine supplemets are recommended to improve the nutritive value of SPL. However, the in vitro researches have reported that SPL can storaged depending on soluble carbohydrates and would be an alternative fodder for ruminants. The purpose of this study is to within the framework of the existing literature, evaluate potential of the use of SPL in animal nutrition.

Tatlı Patates (Ipomoea batatas) Yapraklarının Hayvan Beslemede Kullanımı

Öz

Hem insan sağlığı hem de besleyici özellikleri yönünden önemli bir endüstri bitkisi olan tatlı patatesin, hasat sonrası geriye kalan yeşil aksamları (yaprak ve sap) hayvan beslemede değerlendirilebilen, protein, mineral, vitamin ve karotenoidlerce zengin bir kaba yem materyalidir. Ayrıca yüksek bir aminoasit skoruna da sahiptir. Yılda 6-8 ton/da yeşil aksam alınan ve bunun yaklaşık % 50’sini oluşturan tatlı patates yaprakları (TPY), farklı hayvan türlerinin beslenmesinde taze, kurutulmuş ve silolanmış formlarda kullanılabilmektedir. Nitekim rasyona protein kaynağı olarak kurutulmuş TPY’ı ilavesinin, etlik piliçler, ruminantlar, domuzlar ve balıklarda yem tüketimi ile canlı ağırlığı arttırdığı, yemden yararlanmayı olumsuz etkilemediği bildirilmiştir. Ancak TPY’ nın yem değerini iyileştirmek için lisin desteği önerilmektedir. Diğer yandan in vitro silolama çalışmalarıyla, yemin çözünebilir karbonhidrat içeriğine bağlı olarak oldukça iyi silolandığı ve ruminantlar için alternatif kaba yem kaynağı olabileceği bildirilmiştir. Bu derlemede, mevcut literatürler çerçevesinde, TPY’ nın hayvan beslemede kullanım potansiyelinin irdelenmesi amaçlanmıştır.
