Abstract

The current study was aimed to evaluate the effects of changes in body condition score (BCS) at calving during postpartum period on fertility parameters considering puerperal physiology and metabolic traits in heifers and cows. In Holstein heifers (n=20) and cows (n=20) determined the BCS at calving; BCS, non esterified fatty acids (NEFA) and ß hydroxybutyric acid (β-HBA) levels in days of postpartum 15, 25, 35, 45, 55 of were evaluated. Diameters of uterine horn, follicle numbers, diameters of the largest follicle and the presence of corpus luteum were ultrasonographically defined in mentioned days. Uterine microbiological load in days of insemiantion and postpartum 25 were evaluated. Some fertility parameters of heifer and cows were defined. The average value of BCS was detected higher in cows than heifers at calving and postpartum examination days. Serum NEFA and β-HBA levels during postpartum were higher in heifers compared to cows. Calving to insemination interval and calving to conception interval were detected longer in heifers than cows as well as insemination index were obtained higher in heifers. In conclusion; lower BCS, higher NEFA and BHBA levels reflecting the negative metabolic status during postpartum had the negative effect on fertility in heifers compared to cows. However, It was considered that nutritional management in herds can be monitored qualitatively with BCS or quantitatively with NEFA and BHBA.

Özet

Sunulan çalışmada, düve ve ineklerde doğum anında belirlenen vücut kondisyon skorunun (VKS) postpartum dönemdeki değişiminin puerperal döneme ait fizyolojik ve metabolik bulgular çerçevesinde fertilite parametrelerine etkisinin değerlendirilmesi amaçlanmaktadır. Doğum anı VKS değerleri belirlenen Holstein ırkı düve (n=20) ve ineklerin (n=20) postpartum 15, 25, 35, 45 ve 55. günlerdeki VKS değerleri, serum esterleşmemiş yağ asitleri (NEFA) ve β-hidroksibütirik asit (β-HBA) düzeyleri değerlendirildi. Anılan günlerde kornu uteri çapları, folikül sayıları, en büyük folikül çapı ve korpus luteum varlığı ultrasonografik olarak belirlendi. Postpartum 25. gün ve tohumlama zamanında uterus mikoorganizma yükü belirlendi. Tüm düve ve ineklerin bazı fertilite parametreleri değerlendirildi. İneklerde, doğum anı ile postpartum muayene günlerinde elde edilen ortalama VKS değerlerinin düvelere göre daha yüksek olduğu saptandı. Postpartum süreçte serum NEFA ve β-HBA düzeylerinin düvelerde ineklerden daha yüksek olduğu belirlendi. Düvelerde ineklere göre doğum tohumlama aralığı ve doğum-gebe kalma aralığı daha uzun, tohumlama indeksi ise daha yüksek olarak belirlendi. Sonuç olarak; postpartum süreçte düvelerde düşük VKS değerleri ile yüksek NEFA ve β-HBA düzeylerinin yansıttığı bu negatif metabolik tablonun ineklere göre düvelerde fertiliteyi daha olumsuz etkilediği ve bir sürüde beslenme yönetiminin kalitatif olarak VKS ile, kantitatif olarak da NEFA ve β-HBA ölçümüyle izlenebileceği kanısı oluştu.
