Investigation on The Relationship Between Comperative Body Condition Score and Nefa Levels Among Holstein Cows Raised in Aydin Municipality

This study was conducted to determine the relationship between body condition score and NEFA levels in Holstein cows. The animal material of the study was collected at the 4- to 6-year-old age (from -3 weeks before birth to +3 days after birth) in Ayd?n province Bozdo?an province, which is grown in dairy cattle businesses, Adnan Menderes University Veterinary Faculty, week), the head of the Black Pied Prenatal cow was formed. In the study Black Holstein cows were divided into 3 groups according to BCS: 2 BCS. In the study, the body condition scores of the animals were carried out during the dry period (pre-calving 2 weeks, 15 ± 2 days) and puerperal period (postpartum 2 weeks, 15 ± 3 days). A 5-point system was used when the cow's body condition score (BCS) was determined. In the same period, serum biochemical analyzes were carried out to determine the effect of negative energy balance in animals. NEFA concentration was 0.48 ? 0.089 mmol / L in pre-partum period and 1.01 ? 0.189 mmol / L in 0-15 days after calving (P <0.01). According to BCS classes, NEFA averages were found to be 0.52 ? 0.104 mmol/L and 0.35 ? 0.149 mmol/L in prepartum and postpartum periods, respectively. In the postpartum period, it was determined that there was an increase in NEFA values in cows with increased body condition. The effect of BCS on non-esterified fatty acid concentrations was not found significant (P> 0.05). The relation between BCS and NEFA were investigated by Pearson correlation. The low and negatif correlations (-0.24) was found between BCS and NEFA (P>0.05). As a result, it may be possible to determine energy balances by evaluating the current metabolic profile of cows exhibiting different physiological structure and thus avoiding some metabolic and production problems.
