Vet β-Hydroxybutyrate Monitoring System VBR1

Overview

  • In pastures where grazing is dominant or technical backwardness, the proportion of cows with (subclinical) ketosis is often not effectively controlled. In severe cases, even up to 20 to 30% of cows have ketosis.
  • At least 10 to 20 million cattle worldwide have ketosis including dominant and recessive symptoms, It accounts for 7.7 to 15.4% of global dairy cows.
  • Increase milk production under global carbon displacement pressure：If you find and adopt the captive method to adjust the feed structure for treatment, you can restore at least 10% of milk production.
  • Reduce the cost of treatment for secondary diseases of ketosis：The cost of treatment for secondary diseases will fall by $ 5.68 billion, the cost of treatment for the worsening of cryptogenic ketosis can also fall by $ 806 million.
  • Reduce the cost of breeding failure：The additional cost of breeding failure due to ketosis can be as high as $2.5 billion per year.

The most common cause of low reproductive efficiency in dairy herds

  • Lack of estrus detection
  • Failure to AI at the right time
  • Nutritional or environmentally stress
  • Disease
  • Ketoacidosis is a common nutritional metabolic disease in dairy cows
  • Hypoglycemia, hyperketonemia / low blood sugar , high blood ketone
  • Mainly occurs 2 to 7 weeks after delivery
  • High incidence of high-yielding dairy cows (3 to 6 parity)
  • Occurred in high-yield dairy cows with good management
  • Ideal empty spacing for dairy cows：
    365 days - 280 days = 85 days
  • Reproductive efficiency of dairy cows：
    Ma et al. (1976)：empty spacing 159.6 days
    Feng et al. (1981)：empty spacing 139.9 days
  • Delivering rate：
    42.2% in winter, 27.7% in summer

Shortening the gap between empty spacing is the top priority

Low reproductive efficiency causes serious losses in the agricultural economy

Average production cost per cow

Feeding costs accounted for 54.5%,
A cow costs NT$21 per day, and a loss NT$2891 in 140 days.
