Tridge summary

A recent study by the Harbin University of Agronomic Sciences in China has found that pumpkin seed cake, a by-product of oil extraction, can be used as a replacement for soybean cake in the diet of dairy cows. The research, which was published in ScienceDirect, demonstrated that this replacement does not affect milk yield, ruminal fermentation, or digestibility in dairy cows. In fact, it enhances the antioxidant functions and improves blood parameters in these cows. The study involved six lactating multiparous Holstein dairy cows that were randomly assigned to three groups, all of which had the same nitrogen and forage content.

An investigation carried out by the Harbin University of Agronomic Sciences (China) has shown that pumpkin seed cake (by-product obtained after oil extraction) is a good substitute for soybean cake in the feeding of plants. dairy cows and also has more antioxidant value. The results of the study showed that pumpkin seed cake can be completely substituted for soy cake in the diet of dairy cows without any negative impact on milk yield, ruminal fermentation or apparent digestibility. Furthermore, this dietary change improves antioxidant functions and blood parameters in dairy cows. In the research, 6 lactating multiparous Holstein dairy cows were taken (body weight = 610 ± 21.5 kg, ...
