Effects of Eggshell Thickness, Egg Weight and Shape Index on Hatch Window and Turkey Poults’ Gender

Abstract

The effects of eggshell thickness (EST), shape index (SI) and egg weight (EW) on the hatch window (HW), hatching time (HT), gender of hatched turkey poults hatched were investigated. Total of 150 commercial Hybrid Converter breed turkey hatching eggs obtained from a turkey meat producing integration were used. The effects of these parameters on HW and HT and gender were analyzed via ANOVA-GLM. The hatching window was 656th – 688th hours, and the procedure concluded during the 688th hour of incubation. The incubation was divided into three partitions as early (656 – 667h), midterm (668 – 676h) and late hatches (677 – 688h), with the final 32 hours of incubation divided into 7 partitions (7P) from 1 to 7 as (656 – 664h, 665 – 668h, 669 – 672h, 673 – 676h, 677 – 680h, 681 – 684h and 685 – 688h). A significant relation between EST and gender was found as eggs with thicker EST female chicks hatched more than males (p˂0.05). There was no correlation between gender and EW and SI (p˃0.05). Meanwhile, the number of hatches for 7P, EST, EW and SI were not found to affect the hatch window of turkey eggs (p˃0.05).

Yumurta Kabuğu Kalınlığı, Yumurta Ağırlığı ve Şekil İndeksinin Çıkış Penceresi ve Hindi Civcivlerinin Cinsiyeti Üzerine Etkileri

Öz

Yumurta kabuk kalınlığı (EST), şekil indeksi (SI) ve yumurta ağırlığının (EW) kuluçka penceresi (HW), kuluçka süresi (HT), kuluçkadan çıkan hindi civcivlerinin cinsiyeti üzerine etkileri incelenmiştir. Bir hindi eti üretim entegrasyonundan elde edilen toplam 150 ticari Hybrid Converter cinsi hindi kuluçkalık yumurtası kullanıldı. Bu parametrelerin HW ve HT ve cinsiyet üzerindeki etkileri ANOVA-GLM ile analiz edildi. Kuluçka penceresi 656. – 688. saatlerdi ve prosedür, inkübasyonun 688. saatinde tamamlandı. Kuluçka erken (656 – 667 saat), ara dönem (668 – 676 saat) ve geç çıkım (677 – 688 saat) olarak üç bölüme ayrıldı ve son 32 saat kuluçka, 1'den 7'ye kadar 7 bölüme (7P) bölündü ( 656 – 664s, 665 – 668s, 669 – 672s, 673 – 676s, 677 – 680s, 681 – 684s ve 685 – 688s). Dişi civcivlerin erkeklere göre daha fazla yumurtadan çıkması nedeniyle EST ile cinsiyet arasında anlamlı bir ilişki bulunmuştur (p˂0.05). Cinsiyet ile EW ve SI arasında korelasyon yoktu (p˃0.05). Bu arada, 7P, EST, EW ve SI için çıkış sayısının hindi yumurtalarının çıkış penceresini etkilemediği bulundu (p˃0.05).
