Yumurta Tavuklarında Zorlamalı Tüy Döküm Yöntemleri

Abstract

Yumurtacı tavuklarda yumurtlama döneminin sonunda yumurta verimi ve kalitesi önemli derecede azaldığındanbazı üreticiler verimi artırmak ve eldeki sürüden bir dönem daha ekonomik olarak yararlanmak için sürüyü zorlamalı tüydökümüne sokarlar. Tüy dökümünü sağlayan pek çok yöntem vardır. Bunlar yemin uzaklaştırılması, suyun uzaklaştırılması, ışık süresinin azaltılması, düşük düzeyde kalsiyum yada düşük düzeyde sodyumla, yüksek düzeyde çinko yadaiyot ile yemleme, dane arpa veya yulaf kullanılması ve bazı ilaç-hormonların verilmesidir. İkinci yumurtlama dönemindeyumurta büyüklüğü, kabuk kalitesi ve iç kalite tüy dökümü öncesindeki döneme göre artmaktadır
