Reproductive health diagnosis is a very valuable diagnostic process for me, which can give me a comprehensive understanding of the cattle. Veterinarians usually do "multi tasking" when conducting reproductive tests. During ultrasound examination of the reproductive tract of a cow, the arm will touch the cow's body. At this time, we will naturally be alert to some physiological data, such as body temperature, and whether the trillions of intestinal microbes are digesting the diet well, because they are very important!The Silage Inoculant Bacteria for the cows is also very important!
Cow dung, within reach, also contains important and valuable information. Generally, the faeces of the cows I evaluated are basically homogeneous in texture, normal in shape and free from odor. However, this assessment was very special, and the problems soon emerged.
Cows eat their TMR with relish, but from my veterinarian's point of view, it's different. I can find whole grains of undigested corn in every cow's feces, even when I step on them, I can clearly feel the presence of corn kernels in the feces. Of course, this is not seen from the trough.
In addition, I also noticed that the fecal viscosity of cows lying in bed changed greatly after them. Some of them were loose feces, some were extremely hard or piles of feces. This is a clear warning sign that there is a problem with the total mixed diet (TMR) or cows. In short, the end result of this problem is that the feed intake of dairy cows is reduced, resulting in a decrease in milk production, which can not be compensated for.
As usual, I asked the rancher, "what's the recent change in feeding management?" In this case, he replied that the newly opened corn silage was used in the total mixed diet (TMR). However, no matter forget or have no plan, the quality of silage was not tested before use, and the silage quality in this cellar was not different from that used before, and the quality would not be much different. It turned out to be a costly oversight.
After that, the sensory and chemical analysis of silage showed that the silage in this cellar was quite different from that previously used. It was found that the corn pulverizer failed during the harvest period, but the matter of replacing the pulverizer was forgotten due to the tight time in the harvest season.
The lesson from this mistake is: before feeding, we must actively detect the new feed and adjust the formula according to the results.
