The Use of Colour Cue for Investigating the Ability of Laying Hens to Regulate Methionine Intake from Drinking Water

Yumurta tavuklarının metiyonine istek ve içme suyundan metiyonin alımlarınıdüzenleyebilme kabiliyetleri incelenmiştir. Tavuklar metiyonince yeterli veya yetersiz yemile normal veya metiyonin karışımı su kombinasyonlarına tabi tutulmuştur. Tavuklara Abeslenme döneminde metiyonince yeterli yem ve şişelerden normal su verilmiştir.Tavukların B, C ve D beslenme dönemlerinde normal ve metiyonin karışımı suyu ayırtedebilmeleri için renk belirteci kullanılmıştır. Tavuklarda yem ve içme suyunun fizyolojiketkileri farklı renkteki su şişeleri kullanılarak ilişkilendirilmiştir. Daha sonra denemeninserbest seçim dönemine geçilmiştir. Metiyoninle muamele edilmiş su konsantrasyonu Edöneminde % 0.15 ve F döneminde % 0.30dir. Metiyonince yetersiz besleme yem ve sutüketiminde önemli azalmayla sonuçlanmıştır. İçme sularına metiyonin eklendiğinde yemve su tüketimi normal seviyesine gelmiştir. Diğer taraftan metiyonin tüketimi sadece yemile verildiği zamandaki miktara eşit ya da yem ile verildiği seviyeyi geçmiştir. Sonundatavuklara metiyonince yetersiz yem verilerek normal ve metiyonin karışımı su sunulmuştur.Metiyonince yetersiz yemle beslenen tavuklar renk belirteci vasıtası ile metiyoninli suyunormal suya tercih etmişlerdir. Ancak, tavukların içme suyundan metiyonini ihtiyaçlarıdoğrultusunda alabilme yeteneği gözlenmemiştir.

Renk Belirteci Kullanılarak Yumurta Tavuklarının İçme Suyundan Metiyonin İhtiyacını Düzenleyebilme Kabiliyetlerinin İncelenmesi

The appetite of laying hens for methionine and the hens ability to regulate methionineintake in drinking water were investigated. Birds were subjected to the combinations ofdiet adequate or deficient in methionine and methionine-treated or normal water. Inregimen A, birds were fed diet adequate in methionine and normal water was providedfrom bottles. In order to enable laying hens to differentiate between the water-supplybottles containing normal and methionine-treated water, colour cues and training of thebirds were introduced in Regimens B, C, and D. The birds were allowed to becomeaccustomed to the colour cue of their water supply bottles, and to the physiologicaleffects of their diet and drinking water, then, followed a free choice part of theexperiment. The concentration of methionine in treated water was 0.15% (w/v) inRegiment E, and 0.30% (w/v) in Regiment F. Feeding a diet deficient in methionine resultedin a substantial reduction in the intake of both feed and water. When the drinking waterwas then supplemented with methionine, both feed and water intake was restored to thenormal level, moreover, methionine consumption equalled or exceeded that attainedwhen methionine was supplied in the feed alone. Finally, the hens were fed a methionine - deficient diet and were offered a choice of both normal and methionine-treated water.The hens fed methionine-deficient diet were able to select for water supplemented withmethionine in preference to pure water by using colour cues. However, birds were notable to regulate methionine consumption for their optimum requirements from drinkingwater.
