antimicrobial and preservative properties. It contains specific phytochemicals with structures similar to those of ionophores—molecules that increase the permeability of cell membranes to ions—which can inhibit gram-positive bacteria, making it a very promising natural alternative to antibiotics in animal feed. And phytogenic feed additives can do even more: they are truly viable solutions that alleviate stress-related problems, reduce inflammation, support the immune system and ultimately improve animals’ performance. Anta Phyt is a case in point: it is a phytogenic formulation containing selected hop components and other plant-based ingredients that has been designed to support a healthy microflora in the digestive tract. Numerous studies have shown that Anta Phyt has a beneficial effect on performance parameters such as daily weight gain and feed conversion, as well as animal welfare parameters.
Feeding to improve animal welfare Improved well-being and performance in animals, healthier and safer products for consumers, increased productivity for farmers, more sustainability and protection for the
environment: phytogenic additives promise a lot—and they actually deliver! Results and experience so far show that they really do make a difference in the right combination. Let’s return to our piglets and the challenges of weaning. Here too, phytogenics have great potential. A feeding trial conduct- ed during the rearing period, which also specifically included the first week after weaning, illustrates this. The trial compared the effectiveness of AGPs with that of phytogenic additive Anta Phyt. The numbers are indisputable: the group that received the phytogenic additive showed better growth and feed con- version rates than the AGP group. In fact, as early as the first week, this group showed an additional gain of more than 200 g per animal per day (Figure 1). This continued throughout the entire rearing period and led to a final weight of more than 2 kg higher than the control group (Figure 2). This demonstrates that we can get rid of AGPs, at least in part, and also that we can achieve even better results without them. Phytogenics are the way ahead—a way towards more sustainable produc- tion, less antibiotics, less wasted resources, more safety and health for livestock and humans alike, and more long-term growth and profit for producers. So let’s go for it!
