The impact of supplementing plant tannin on the milk yield and milk quality of lactating dairy cows

Original language description

Tannins are natural polyphenolic compounds that can be included in a dairy cattle diet in order to overcome problems related to low-quality protein in forages, especially in a dry season. Using plant tannins as a feed supplement could be beneficial in protecting the protein from degradation in the rumen and, therefore, efficiently increasing bypass protein, which may result in improved animal performance and production quality. However, little is known about their effect on milk production and quality. This study aimed to evaluate the impact of dietary tannins on milk yield and milk composition of dairy cattle. Our results didn’t show a significant (P = 1,17) effect of tannin supplementation on the milk yield. The weighted average milk yield was estimated to be 36,8 kg/day in the control group and 40,4 kg/day in the experimental group supplemented with tannin extracts. However, dietary tannins significantly affected milk composition parameters (P = 0,001). Protein and fat percentage were significantly (P < 0,01) lower in the experimental group compared to control. The concentration of SC and urea were markedly increased (P < 0,01) with tannin supplementation. In conclusion, the tannin extracts can be recommended as a feed supplement for dairy cattle after considering the type of tannins and dosages. Further research related to the impact of tannins on milk production is necessary.
