Anadolu Mandalarında Kuru Dönem Uzunluğunun Erken Laktasyon Döneminde Ortalama Süt Verimi Üzerine Etkisi

Öz

Bu çalışma, Anadolu mandalarında kısa ve uzun kuru dönem sürelerinin sonraki erken laktasyon dönemindeki süt verimine etkisini araştırmayı amaçladı. Mandalar (n=64) kısa kuru dönem (Grup SD; n=17; ≤6 hafta), normal kuru dönem (Grup ND; n=20; 8-10 hafta) ve uzun kuru dönem (Grup LD; n=27; ≥12 hafta) olarak üç gruba ayrıldı. Tüm grupların erken laktasyon süt verimleri ve laktasyon sayıları istatistiksel olarak kıyaslandı. Laktasyon sayıları açısından SD, ND ve LD grupları arasında bir fark yoktu (p >0.05). Erken laktasyon dönemindeki süt verimi diğer gruplara göre SD grubunda daha düşüktü (p <0.05). Ancak, ND ve LD gruplarının erken laktasyon dönemindeki süt verimlerinin benzer olduğu bulundu (p >0.05). Sonuç olarak, Anadolu mandalarında erken laktasyon döneminde kısa kuru dönem süt verimini olumsuz yönde etkiledi. Öte yandan, normal ve uzun kuru dönem uzunluklarına sahip olan hayvanlar benzer bir süt verimine sahipti. Ancak, daha kesin bir sonuç için süt veriminin tüm laktasyon dönemi boyunca takip edilmesi gerektiği düşünülmektedir.

The Effect of Dry Period Length on Average Milk Yield in Early Lactation Period in Anatolian Buffaloes

Abstract

This study aimed to investigate the effect of short and long dry period on milk yield in next early lactation period in Anatolian buffalo. The buffaloes (n=64) were assigned to three groups as a short dry period (Group SD; n=17; ≤6 weeks), a normal dry period (Group ND; n=20; 8-10 weeks) and a long dry period (Group LD; n=27; ≥12 weeks). Early lactation milk yields and lactation numbers of all groups were compared statistically. It was observed that there was no difference between SD, ND and LD groups in terms of lactation numbers (p >0.05). The milk yield in the early lactation was lower in the SD group compared to the other groups (p <0.05). There was no difference in milk yield in the early lactation period of the ND and LD groups (p >0.05). However, it was found that the milk yields of the ND and LD groups were similar in the early lactation period. In conclusion, short dry period had a negative effect on milk yield in early lactation period in Anatolian buffaloes. On the other hand, animals with normal and long dry periods had a similar milk yield. However, we think that milk yield should be followed throughout all lactation period for a more precise result.
