Do ionophores improve average daily gain (ADG), feed efficiency, and reduce incidences of coccidiosis and bloat?

1. True

2. False

The correct answer is: True

Ionophores are compounds that are used in the cattle industry primarily as feed additives. They have been shown to have several beneficial effects when included in the diets of cattle, particularly in terms of improving performance and animal health. In terms of average daily gain (ADG), ionophores can improve feed efficiency by altering the fermentation process in the rumen. This leads to a greater proportion of energy being utilized for growth rather than being lost. By promoting a more favorable microbial population, ionophores help in better digestion of feed, which enhances ADG. Additionally, ionophores help in reducing the incidence of coccidiosis, a common parasitic disease in cattle that affects the intestinal tract. By inhibiting the growth of certain protozoa, ionophores can help in controlling and preventing outbreaks of this disease, thereby improving overall health and productivity. Furthermore, ionophores can also help in alleviating bloat, which is a condition caused by excessive gas accumulation in the rumen. By modulating the rumen fermentation process, these additives can help reduce the risk of bloat, making them beneficial for herd health. Overall, the use of ionophores contributes positively to both the growth performance of cattle and their health, supporting
