Beta Vet is an oral solution with betaine, menthol, vitamin C and electrolytes. These compounds prevent dehydration by retaining water within the cells, reestablish the hydroelectrolytic balance, help control hormones such as corticosterone and help prevent fatty liver. In addition, menthol provides a cooling sensation, contributing to the well-being of birds.HEAT STRESS IN POULTRY FARMING Heat stress management is one of the most important challenges facing poultry production during the summer. The effects of heat stress affect both broilers and layers, reducing their productivity and affecting animal welfare.(RE)PRODUCTIVE CONSEQUENCES Increased body temperature causes birds to reduce their feed intake, which affects their growth. It also causes metabolic alkalosis that promotes calcium imbalance, which in layers affects the quality and size of the eggshell. Thermal stress also inactivates some non-essential functions, such as reproduction, which leads to a decrease in fertility.
