The large nutritional chemical segment will account for over one-quarter of the growth seen during the forecast period, as these products — which include amino acids, vitamins, minerals, enzymes, and other products— remain vital as feed additives and dietary supplements. Consumer interest in natural products will continue to favorably impact the nutritional chemical segment as products such as acidifiers, amino acids, carotenoids, enzymes, herbs, probiotics, and other ingredients with a more “natural” profile are used to replace more controversial additives.
The importance of preventive health care will support growth in parasiticides and vaccines. Parasiticides will remain a prominent feature in the care of pets and livestock, as prevention of and treatment for existing fleas, ticks, and other pests will help reduce occurrences of pest-related health disorders. Furthermore, fears about antibiotic resistance are leading to increased use of diagnostics to treat only animals requiring care, rather than medicating entire herds or flocks, driving above average gains in this product segment.
Livestock and poultry will continue to account for the dominant share of animal health product sales through 2016 due to the sheer size and importance of the US commercial animal segment. However, companion animal applications will remain the fastest growing and will continue to increase their share of demand. Ownership trends favoring higher spending on pet health — such as on preventive products including parasiticides, and on food and supplements featuring nutritional chemical content -- will encourage ongoing above average sales gains.
