İkizliğin İleri gebe koyunlar ve bunların kuzularında mineral madde, immunglobulin G ve kuzu doğum ağırlığı üzerine etkisi

Öz

Sunulan çalışmada, ileri gebe koyunlar ve bunlardan doğan kuzularda ikizlik durumunun mineral madde, Immunoglobulin G (IgG) ve kuzu doğum ağırlığı üzerine etkilerini araştırmak amaçlandı. Çalışmanın materyalini gebeliğin 130-150. günleri arasında Kıvırcık ırkı 18 adet koyun ile bunların yeni doğan 27 adet kuzusu oluşturdu. Çalışmaya alınan koyunlar ultrason ile tek gebelik (n=9) ve ikiz gebelik (n=9) taşıyanlar olarak iki gruba ayrıldı. Vücut Kondüsyon Skorları (VKS) belirlendi ve kan örnekleri alındı. Bu koyunlardan doğan kuzular doğar doğmaz hassas terazi ile tartıldı ve doğumdan 24 saat sonra kan örnekleri alındı. Alınan kan örneklerden mineral madde tayini ICP-OES, IgG tayini ELISA ile yapıldı. Koyunlarda serum IgG ve mineral madde düzeylerinin ikizlikten etkilenmediği görüldü (P>0.05). İkiz kuzularda Kalsiyum (Ca) düzeyi tek kuzulara göre önemli derecede yüksekti (P<0.05). Diğer mineraller ve IgG konsantrasyonu bakımından tek ve ikiz kuzular arasında istatistiki açıdan fark yoktu (P>0.05). Tek kuzularda total protein ve globulin değerleri ikiz kuzulara göre anlamlı derecede yüksek bulundu (P<0.05). Tek doğan kuzuların ikizlere göre anlamlı derecede ağır olduğu (P<0.05), erkek kuzuların dişilere göre daha ağır olmakla birlikte aralarındaki farkın istatistiki açıdan önemli olmadığı (P>0.05) bulundu. Sonuç olarak; ileri gebe koyunlarda ikizliğin ve VKS’nin mineral madde, IgG, total protein, albumin ve globulin düzeylerini etkilemediği, kuzularda ise ikizliğin kuzu doğum ağırlığı, total protein, globulin ve Ca değerlerini etkilerken, diğer mineraller ve IgG düzeylerini etkilemediği tespit edildi. İkiz kuzularda total protein ve globulin konsantrasyonlarının anlamlı derecede düşük olması bu hayvanların yeterince kolostrum ememediğini düşündürmektedir.

The effect of twinship on mineral matter, immunoglobulin G and lamb birth weight in late pregnant ewes and their newborn lambs

Öz

The aim of this study was to investigate the effects of twinship on the mineral matter, immunoglobulin G (IgG), and lamb birth weight in late pregnant ewes and their lambs. The material of the study consisted of the 18 Kıvırcık breed ewes, which were 130-150 days pregnant, and their 27 newborn lambs. The ewes included in the study were divided into two groups by ultrasound as those carrying a single pregnancy (n=9) and a twin pregnancy (n=9). Body Condition Scores (BCS) were determined and then their blood samples were taken. The lambs born from these ewes were weighed with precision scales as soon as they were born, and blood samples were taken 24 hours after birth. Mineral substance determination from blood samples was made by ICP-OES, and IgG determination was made by ELISA. It was found that serum IgG and mineral matter levels were not affected by twinship in ewes (p>0.05). Calcium (Ca) level was significantly higher in twin lambs compared to single lambs (p<0.05). There was no statistical difference between single and twin lambs in terms of other minerals and IgG concentrations (P>0.05). Total protein and globulin values were significantly higher in single lambs than twin lambs (P <0.05). It was determined that single-born lambs were significantly heavier than twins (P<0.05), and while male lambs were heavier than females, the difference between them was not statistically significant (P>0.05). As a result, it was determined that twinship and BCS did not affect the mineral substance, total protein, albumin, globulin and IgG levels in late pregnant ewes, while twinship in lambs affected lamb birth weight, total protein, globulin and Ca values, but not other mineral and IgG levels. Significantly low total protein and globulin concentrations in twin lambs suggest that these animals cannot absorb enough colostrum.
