Yerli Kara ve İsviçre Esmeri Irkı Sığırların Kolostrum Kalitesinin Karşılaştırılması

Ruminant plasentaları sindesmokoryal tipte olduğu için maternal sirkülasyonla yavru sirkülasyonubirbirinden ayrılmaktadır. Bu sebeple yenidoğan buzağılar neonatal dönem olarak da isimlendirilendoğumu takiben ilk 28 günlük periyotta, annelerinin kolostrumundan alacakları bağışıklıkbileşenlerine ihtiyaç duyarlar. Pasif immun transfer başarısı için toplam kolostralImmunlobülinlerinlerin %85-90’ını oluşturan Immunglobülin G’nin kolostrumdaki miktarı kalitenoktasında belirleyicidir. Çalışmanın amacı; yerli gen kaynaklarımızdan olan Yerli Kara ırkı sığırlarile kombine verimli bir kültür ırkı olan İsviçre Esmeri’nin kolostrum kalitelerinin karşılaştırılmasıdır.Çalışmanın hayvan materyalini 40 saf Yerli Kara sığır ve 39 saf İsviçre Esmeri sığır oluşturdu.Kolostrum Immunglobulin G seviyesi ELISA yöntemi kullanılarak belirlendi. Yerli Kara ve İsviçreEsmeri sığırların tanımlayıcı istatistik verilerine göre ortalama Immunglobulin G konsantrasyonlarısırasıyla; 133.1±77.28 mg/mL, 74.60±28.44 mg/mL olduğu tespit edildi. İki grup arasındakiImmunglobulin G verileri bağımsız t testi ile karşılaştırıldığında istatistiksel olarak önemli olduğutespit edildi (P

Colostrum Quality Comparison of Native Black and Brown Swiss Breed Cattle

Maternal circulation and calf circulation are separated from each other since the type of ruminant placenta is syndesmochorial. Therefore, newborn calves need the immunity compounds from the colostrum of their mothers in the first 28 days after birth, which is also called neonatal period. The amount of Immunoglobulin G, which constitutes 85-90% of the total immunoglobulin, plays a significant role in determining the quality in the colostrum for an effective passive immune transfer. The aim of this study was to compare the colostrum quality of Native Black breed cattle, which is one of our native gene sources, and Brown Swiss cattle, which is a combined milk-oriented culture breed. The animal material of the study consisted of 23 pure Native Black cattle and 43 pure Brown Swiss cattle. ELISA method was used to determine the colostrum immunoglobulin G level. According to the descriptive statistical data of Native Black and Brown Swiss cattle, mean Immunoglobulin G concentrations were found as 133.1±77.28 mg/mL and 74.60±28.44 mg/mL, respectively. Immunoglobulin G data between the two groups were found to be statistically significant when compared with the independent t-test. (P
