“…The highest prevalence of 50.0% during 1 st and 2 nd month of lactation was recorded [18], and the prevalence of 42.8% during 1 st month followed by 28.6% during 2 nd month of lactation period [32] are in close proximity to the present findings. The highest prevalence has also been reported during the 1 st month of lactation which was in line with the present findings [2,27,28,33-36]. …”

Aim:The present study was conducted to ascertain the prevalence of ketosis in dairy cows in dairy herds, milksheds, and mixed population of milk cows selected randomly in milkshed areas of Odisha state, India.Materials and Methods:The investigation was conducted in 280 private dairy herds with variable herd size of 10-15 cows comprising crossbred Jersey cows (CBJ), crossbred Holstein Friesian (CHF) cows, and indigenous local breeds. The analysis of urine (Rothera’s test), milk (Ross test), and blood samples of 2760 test cows were conducted through qualitative assessment by Rothera’s test and Ross test, respectively, for the presence of ketone bodies to screen the ketotic animals. Cut-points have been decided based on β-hydroxybutyric acid level (≥1.2-1.4 mmol/L) in milk.Results:We noted positive cases of ketosis with a prevalence rate of 36.7% (1014/2760) entailing 27.2% in clinical ketosis and 9.6% in subclinical ketosis. The breed wise incident rate was recorded to be the highest (38.0%) in CBJs. The age-wise prevalence rate was found to be the highest (40.8%) in the age group of 5.5-6.5 years. The season wise prevalence rate in 5th calver was recorded to be the highest (38.6%) in summer season as compared to other seasons. The prevalence of ketosis was observed to be the highest at 56.7% on the first stage of lactation at the 1st month after 2 weeks. The incidence rates for clinical and subclinical ketosis were found to be 25.2%; 12.2%, 26.6%; 11.2% and 30.3%; 2.9% in CBJ, CHF and indigenous cows, respectively. The breed wise overall prevalence rate was recorded to be 38.0% in CBJ, 37.8% in CHF, and 33.2% in indigenous cows.Conclusion:Ketosis and subclinical ketosis is highly prevalent metabolic disorder and has severe effect on the production status of affected animal and needs to be prevented, rather than treated, by maintaining cows in good and healthy conditions. We have attempted to give great attention for diagnosis, management, and control of this disease during risk stage to prevent economic loss sustained by the dairy farmers of Eastern India.

The purpose of this study was to estimate the prevalence of Subclinical ketosis (SCK) between 4 and 19 days in milk (DIM) in a grazing production system and investigate the importance of potential risk factors for SCK. This cross-sectional study was conducted in dairy cows (n = 107), which had more of two parities. The concentration of β-hydroxybutyric (BHB) in blood was quantified through a hand-held meter. Potential risk factors evaluated were calving interval (CI), milk yield in previous lactation, metritis, dystocia, calf sex (male), parity (≤3 vs. ≥4) and pre-partum body condition score (BCS ≤ 3.5 vs. ≥3.75). Prevalence of SCK was 10.3% (95% CI 4.7-15) between 4 and 19 DIM. Risk factors identified were the occurrence of both metritis and pre-partum BCS ≥ 3.75. Cows with metritis had 4.9 (95% CI 1.17-20.98) times more risk of developing SCK than cows without metritis. And the cows with pre-partum BCS ≥ 3.75 had 5.25 (95% CI 1.32-21.11) times more risk of developing SCK than cows with pre-partum BCS ≤ 3.5. Metritis could induce a lower feed intake and promote the development of SCK. High pre-partum BCS could induce a greater mobilization of body reserves altering liver function and aggravating post-partum NEB. The results are indicative of the expected prevalence of SCK in grazing production system. Factors associated could help to identify cattle at risk of SCK and improve the management of strategies to limit the effects.

Başbuğ O, Akar Y, Ercan N. Sivas yöresindeki süt sığırlarında subklinik ketozisin prevalansının araştırılması. Amaç: Türkiye'de subklinik ketozisin (SKK) prevalansının belirlenmesine yönelik sınırlı sayıda çalışma yapılmıştır. Bu çalışmada, Türkiye'nın Sivas ilindeki süt sığırı işletmelerinde bulunan Holştayn süt ineklerinde SKK'in prevalansının belirlenmesi ve serum β-hidroksibütirat (BHB) ile glikoneogenezisde rol alan glikoz, albümin ve total kolesterol konsantrasyonları arasındaki ilişkinin tespit edilmesi amaçlandı. Gereç ve Yöntem: Çalışmada yaşları 3-6 arasında değişen, kuru dönem (40 baş) ve doğumdan sonraki 1-8 haftalar (160 baş) arasında bulunan toplam 200 baş holştayn inekler kullanıldı. Sistematik klinik muayenesi yapılan hayvanlardan kan örnekleri alındı. SKK'li ineklerin belirlenmesinde eşik değeri olarak 1.0 mmol/L BHB düzeyi alındı. Tüm ineklerin serum glikoz, albümin ve total kolesterol düzeyleri belirlendi. Bulgular: Sivas yöresinde yetiştirilen Holştayn ırkı ineklerde SKK prevalansı %12 olarak tespit edildi. SKK'lı ineklerin kan BHB seviyelerinin laktasyonun ilk haftalarında daha yüksek seviyelerde seyrettiği, kan glikoz ve total kolesterol düzeyleri ile arasında negatif korelasyonun olduğu belirlendi. Öneri: Süt verimi yüksek olan işletmelerde, periyodik aralıklarla BHB düzeylerinin belirlenmesi ve yüksek BHB'li ineklerde gerekli önlemlerin alınması yararlı olacaktır.
