Crisis of the decline in cattle numbers Materials on the topic were distributed to dairy farmers in Hokkaido.

The sense of crisis in dairy numbers decreased

As you can see on the chart, the number of dairy cows is decreasing over the years across the country. In Hokkaido, the number of heifers

there has been a decline of about 35,000 and the number of heifers has decreased by around 6,000 in the past six years. At this rate, we cannot expect to maintain and expand production of raw fresh milk.

* Multiple litters of dairy cows: Dairy cows have gone through a period of giving birth

Possible causes of the decline in dairy numbers include an increase in the number of crossbred cows due to the high individual prices, accidents in calves and milking cows, and poor reproductive performance.

Dairy cows account for the largest share of agricultural output in Hokkaido with 36%, accounting for more than 50% of total livestock production. Furthermore, Hokkaido accounts for 48% of national fresh milk production and 61% for dairy cows, indicating that the decline in dairy cow population is a serious problem in Hokkaido. (* first)

Every dairy farmer strives to make the cows live longer

Up to now, in terms of facilities and equipment for dairy cows, the herd has been increased, the scale has been increased, and the establishment of milking robots is actively automated and foreignized. On the other hand, the detailed care and consideration in livestock to minimize livestock accidents and keep them healthy are ignored.

For example, in 2005, the number of deaths and accidents among dairy calves in Hokkaido was 16,112 and the damage rate was 7.2%. If the rate of damage remains at 7%, the dairy industry, arguably the mainstay of Hokkaido’s economy, could suffer huge economic losses. However, even in figures for 2014, 10 years later, the damage rate is 6.9%, almost unchanged.

In order not to reduce the dairy herd any more, relevant organizations must coordinate to sound alarm bells. It is important for each dairy farmer to be aware of the crisis and to simply increase the number of cows, striving for the mother cow and the calf to be born for as long as possible. Such movements are now gradually spreading in Hokkaido.

An introduction to each dairy farmer’s efforts

What every dairy farmer can do without reducing the number of dairy cows is securing the heirs for milk and ensuring long-term continuous production. There are three things: “Increase the number of cows born”.

So in the technical documentation “Here’s my approach!” Compiled by the Hokkaido Dairy Inspection and Certification Association, we present three effortless methods that dairy farmers are practicing on each topic.

The specific methods to “reduce the number of dead cows” are to reduce mortality without calving calves at birth, reduce the postnatal mortality rate without calving postpartum calves and mothers. To reduce dropout and mortality without dying both calves. It is also important to reduce the rate of postpartum rejection. Regarding those methods, the “my way” of each dairy farmer is introduced in detail.

For example, in the case of K farm in Hidaka, which boasts zero mortality for calves within 3 months of birth of zero. In order to prevent death of calves born, it is advisable to let calves lay naturally As possible, after calving, let the mother cow lick the calf meat, handle the umbilical cord, then dry the calf and put it in the calf nest which is a hut for the calf. I try to put it in.

The calf’s morbidity depends on the owner’s belief that umbilical cord treatment is carried out. We measure calves temperature every day and try to detect early stage abnormalities. In addition, we believe that healthy calves are born from healthy mothers, so we carefully manage the mother’s health.

The most important thing is that the herds we raise are familiar with the environment and we are focusing on self-produced inheritance.

Many voices say “How useful!”

“Up to now, I am very pleased because there are no documents summarizing in a systematic and methodical way from breeding, reproduction to growth of dairy cows.” How are other dairy farmers doing? It helps to know if they are doing it or not. “We received comments that we would like to take this opportunity to review our efforts,” said the Hokkaido Dairy Certification Inspection Association. The person in charge of the headquarters is also talking.

Maintain inherited dairy herd with the goal of increasing production of raw fresh milk from 3.9 million tons in 2017 to 4 million tons after 10 years in “The 7th plan to modernize dairy farming and Hokkaido meat.” We will endeavor to expand and produce continuously for a long time.
