Economic optimization of selective dry cow treatment

Economic aspects of dry cow therapy

Dry cow therapy has been part of mastitis control since the 1970s and has been one point of the five point scheme. In many countries many, if not most, dairy farmers apply dry cow therapy as part of their farm specific mastitis control plan. The general advice in the five point plan is that all cows, at drying off, should be treated with a specific long acting antibiotic formulation the blanket...

Optimization of dry period in Karan Fries cow

AIM The objective of this study was to optimize dry period (DP) length that can maximize the production across adjacent lactations and overall lifetime yield. MATERIALS AND METHODS Performance records with respect to DP spread over a period of 15-year in Karan Fries (KF) cattle maintained at Livestock Research Centre (National Dairy Research Institute), were collected for the study. Data of 6...

economic optimization and energy consumption in tray dryers

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...

Mastitis Prevention and Cure Rates in Heifers Treated with Spectramast Dry Cow Therapy and/or Orbeseal Dry Cow Teat Sealant

Dairy cows are vital for milk production, cheese, cream, and so much more. Healthy udders and teats are necessary to keep production levels at their highest and to keep the number of cows being culled to the lowest levels. Inflammation of the mammary gland is called mastitis, which is typically caused by bacteria that invade the teat canal. This disease is most often transmitted by contact with...
