High temperatures lead to hidden costs among your livestock
The number of hot days is increasing. High temperatures during dry-off periods affect not only the cow, but also the unborn calf. The consequences for the calf can later manifest in a milk production that is 16% lower than average.
A relatively short period of high temperatures in late pregnancy can dramatically affect the health, growth and eventual performance of dairy calves. It is therefore crucial to effectively combat the influence of high temperatures in dry cows to avoid negative effects on the calf. The calves of a cow that has not been affected by the hot weather are on average three kilograms heavier when they are born. In addition, they have a better immunity. This is because colostrum contains more antibodies and is better absorbed. Calves from these cows also appear to absorb 43% more antibodies (IgGs) from the same colostrum than calves from non-cooled cows (Monteiro et al., 2016).
16% Increased milk production
Optimising the living environment during situations of warm temperature has a favourable effect on the mother and therefore also on the calf’s weight development. These calves grow on average 0.2 kg more per day until weaning and are then considerably heavier when they go off the milk. The loss to the end of the first lactation is more than twice as low. Milk production is also 16% higher than average. It has also been shown that calves from a cooled mother conceive more easily and at a younger age. It is therefore very important to provide your herd with the best possible temperature. Both for animal health and production on your dairy farm.
Cow’s appetite optimised despite hot weather
Ensuring optimal milk yield is one of the biggest challenges during situations where stress can be expected due to hot weather. Optimising living conditions during dry-off periods can boost milk production in the next lactation by an average of 4-5 litres. The cow loses less energy pumping blood through the skin. This blood can then be used in the udder for milk production and in the organs for energy absorption. A cow’s appetite is also improved when she is in a pleasant climate.
Optimal health of the liver
Optimum feed intake means that the cow receives sufficient energy and protein. The cow better maintains milk production and lactose content. In addition, the cow does not have to compensate for energy shortages, resulting in an optimum condition.
The AHV Booster Tablet optimises the energy balance by activating the cow’s metabolism (liver and rumen). It will help the liver to prevent fat breakdown. Graph 1 below shows the average rumination activity (rumination time, in minutes) of cows with and without a non-optimal energy balance, to x days after calving. These values have been validated based on research by Kaufman et al (2016).
Improve rumination activity with AHV Booster solutions
A test population of 25 cows, showing signs of a non-optimal energy balance, were given an AHV Booster solution (The AHV Booster Tablet). This solution was administered between day 7 and 8 after calving. The support of the AHV solution in starting the rumination activity is shown in the graph; the average rumination activity quickly rose to the average value for cows.
Dairy farmer Niehof-Velthuis (The Netherlands):
“The AHV Booster Tablet is a really nice product and I like it. The Booster is fast and long-lasting, and is well absorbed by the cow. We see the milk production increase and that the cow starts eating more than ever. We have cows that recover quickly after a few days. We can clearly see these results in the data.”
