The polyphenol based products of Nat-Phen have provided us a feed ration more economic in our herd because of the improvement in feed digestion. Therefore, the feed consumption has decreased of 1 kg of wet corn and of 0,5 kg of soybean per cow per day with the same milk quantity produced.
However, the most important effect observed was about the fertility. The pregnancy rate in cows have increased of 10% since we use Nat-Phen products in our herd. Now, this rate is about 42% (the calculation of the percentage is based on the number of pregnancy cows against the number of open cows). Also, heats are more visible and cows are in better health.
