Effects of milking and adlibitum sucking during the early lactation period on metabolic profile of exes delivered single or multiple lambs

Bu çalışmanın amacı, kolostrumun en yoğun salgılandığı doğumdan sonraki ilk 24 saate kontrollü sağılımın ve çoklu doğumlarda tek yavru tarafından emilimin koyunların metabolik profiline etkisini ortaya çıkarmaktır. Çalışmada yeni doğum yapmış 21 adet koyun kullanılmıştır. Tek yavru doğuran yedi adet koyunun kuzuları doğumun hemen ardından annelerini emmeleri engellenerek ağıldan çıkarılmışlardır. Bu koyunlardan Grup I oluşturulmuştur. Tek yavru doğurmuş diğer yedi adet koyunun yavruları ağılda bırakılarak annelerini adlibitum emmeleri sağlanmıştır. Bu koyunlardan da Grup II oluşturulmuştur. Son olarak ikiz ve üçüz yavru doğurmuş olan yedi adet koyunun yavrularından bir tanesi annenin yanında bırakılarak annelerini emmesine izin verilirken, diğer yavrular doğumun hemen ardından ağıldan uzaklaştırılmışlardır. Bu gruptaki koyunlar da Grup III'ü oluşturmuştur. Tüm gruplardaki koyunlardan doğumdan sonraki 0, 6, 18, 24. saatlerde plazma örnekleri toplanarak total protein, globulin, albumin, üre, glukoz, total lipid ve kolesterol konsantrasyonları ile albumin/globulin oranı belirlenmiştir. Plazma total protein ve globulin konsantrasyonlarının Grup III'de 18. saatte ve total lipid ile kolesterol konsantrasyonlarının da 6. saatte Grup I'den p

Tek ve çoklu doğum yapmış koyunlarda sağılmanın ve adlibitum emilmenin erken laktasyon döneminde metobolik profile etkisi

The objective of the current study was to investigate the effects of controlled-milking or sucking by a single lamb instead of multiple offspring within the first 24 h after birth, the time period when the secretion of colostrum was the highest, on the metabolic profiles of ewes. A total of 21 ewes that delivered lambs were used. The lambs of seven ewes that delivered single offspring were separated from their mothers right after birth without sucking. These ewes were accounted as Group I in the study. Another group of seven ewes that also delivered single lambs were allowed to stay with their offspring with sucking colostrum adlibitum. This group of ewes was the Group II in the study. Group III was composed of ewes that delivered twins or triplets but allowed to stay with only one offspring with adlibitum sucking of colostrum. Blood samples were collected from all animals in all groups at immediately after birth (0 h), and 6, 18, and 24 h following birth. The samples were analyzed for concentrations of total protein, albumin, urea, glucose, total lipids, and cholesterol. Plasma globulin concentrations and albumin/globulin ratio (A/G) in the samples were determined by calculation. Results indicated that plasma protein and globulin concentrations at 18 h and total lipids and cholesterol concentrations at 6 h were significantly (p
