Abstract
Bu araştırmanın amacı, süt ineklerinde tohumlamaya yakın dönemlerde enerji takviyesinin yapılıp yapılmamasının ve/veya farklı enerji takviyelerinin fertilite üzerindeki etkilerini araştırmaktır. Araştırmanın deneysel aşaması iki aşamadan oluşmaktadır. Birinci aşamasında, 392 adet holstein inek dört farklı gruba şu şekilde ayrılmıştır: Kontrol1 Grubunda (n=94) ineklere enerji takviyesi yapılmamış ve 46 adet ineğe Ovsynch, 48 adet ineğe ise Modifiye G6G protokolü uygulanmıştır. 2. Grup (n=96) ineklere suni tohumlama öncesi üç gün enerji içerikli bolus uygulanmış ve 48 adet ineğe Ovsynch, 48 adet ineğe ise Modifiye G6G protokolü uygulanmıştır. 3. Grup (n=105) ineklere suni tohumlama sonrası üç gün enerji içerikli bolus uygulanmış ve 55 adet ineğe Ovsynch, 50 adet ineğe ise Modifiye G6G protokolü uygulanmıştır. 4. Grup (n=97) ineklere suni tohumlama öncesi üç gün ve suni tohumlama sonrası üç gün enerji içerikli bolus uygulanmış ve 50 adet ineğe Ovsynch, 47 adet ineğe ise Modifiye G6G protokolü uygulanmıştır. Araştırmanın ikinci aşamasında ise 100 adet holstein inek Kontrol2, Gliserol, Propilen glikol (PG) ve Bolus olmak üzere dört farklı gruba ayrılmış ve Modifiye G6G protokolü uygulanmıştır. Kontrol2 grubuna enerji takviyesi yapılmamış, PG grubuna 350 ml monopropilen glikol, Gliserol grubunda 450 ml gliserol ve Bolus grubuna ise enerji içerikli bolus suni tohumlama öncesi üç gün, suni tohumlama gününde ve suni tohumlamadan sonraki üç gün olmak üzere toplam yedi gün uygulanmıştır. Gebelik muayeneleri suni tohumlamadan 30 ve 70 gün sonra ultrason kullanılarak yapılmıştır. Çalışmanın birinci aşamasında, Ovsynch ve Modifiye G6G protokollerinde, gruplar arasında birinci ve ikinci gebelik performansı ve süt verimleri bakımından fark gözlemlenmemiştir (P>0,05). Çalışmanın ikinci aşamasında, birinci ve ikinci gebelikte gruplar arasında gebelik performansı ve süt verimleri bakımından fark saptanmamıştır (P>0,05). Bu araştırmadan, tohumlama öncesi veya sonrası dönemde yapılan kaynağı farklı enerji takviyesinin gebelik performansı ve süt verimi üzerine etkisi olmadığı sonucu çıkarılmıştır.
The aim of this study was to investigate whether energy supplementation should be applied close to insemination and/or the effects of different energy supplements on fertility in dairy cows. The experimental phase of the study consisted of two stages. In the first stage, 392 Holstein cows were divided into four different groups as follows: Group Control1 (n=94) cows were not given energy supplementation and 46 cows received Ovsynch and 48 cows received the Modified G6G protocol. Group 2 (n=96) cows received energy bolus for three days before artificial insemination and 48 cows received Ovsynch and 48 cows received the Modified G6G protocol. Group 3 (n=105) cows received energy bolus for three days after artificial insemination and 55 cows received Ovsynch and 50 cows received the Modified G6G protocol. 4. Group (n=97) cows were given energy bolus for three days before and three days after artificial insemination and 50 cows were given Ovsynch and 47 cows were given Modified G6G protocol. In the second phase of the study, 100 Holstein cows were divided into four groups as Control2, Glycerol, Propylene glycol (PG) and Bolus and were given Modified G6G protocol. No energy supplement was given to the Control2 group, PG group received 350 ml monopropylene glycol, Glycerol group received 450 ml glycerol and Bolus group received energy bolus for three days before artificial insemination, on the day of artificial insemination and three days after artificial insemination for a total of seven days. Pregnancy examinations were performed using ultrasound 30 and 70 days after artificial insemination. In the first phase of the study, no difference was observed between the groups in the Ovsynch and Modified G6G protocols in terms of first and second pregnancy performance and milk yield (P>0.05). In the second phase of the study, no difference was observed between the groups in terms of pregnancy performance and milk yield in the first and second pregnancy (P>0.05). It was concluded from this study that energy supplementation from different sources before or after insemination had no effect on pregnancy performance and milk yield.
