Why is animal health important?

Animal health is essential to the efficient production of wholesome animal products. An example of the economic effect of animal-disease research conducted by veterinary scientists is the control of Marek’s disease, a highly contagious disease affecting the nerves and visceral organs of chickens, which resulted in a loss of more than $200,000,000 annually to the U.S. poultry industry alone. The disease was studied for more than 30 years before it was learned that it is caused by a herpes virus. Within three years of this discovery, a vaccine was developed that reduced the frequency of Marek’s disease and the resultant meat condemnations in vaccinated chickens by 90 percent and increased egg production by 4 percent. Veterinary scientists also investigate the chronic infectious diseases associated with high morbidity rates and various metabolic disorders.

What are intensive systems of animal production?

Farmers have widely adopted intensive systems of animal production, and these systems continue to present opportunities and problems to animal scientists concerned with discovering and accommodating the environmental and ethological needs of food animals.

What is animal ecology?

Animal ecology and ethology are relatively young branches of the animal sciences. Around the middle of the 20th century, environmental physiologists in the United States and the United Kingdom began to study agricultural animals’ relations with their environment, including temperature, air, light, and diet. Interactions among environmental temperature, diet, and the animals’ genetic makeup have been characterized, and great strides have been made in improving thermal-environmental management on farms. Lighting management is now essential to profitable poultry production, and the light environment is being controlled in livestock houses as well. Since the 1970s emphasis has shifted to include the behavioral adaptability of animals to their surroundings and the effects of environmental stress on the immune status of livestock and poultry. Farmers have widely adopted intensive systems of animal production, and these systems continue to present opportunities and problems to animal scientists concerned with discovering and accommodating the environmental and ethological needs of food animals.

Why are farm animals important?

Third, farm animals are critical to a sustainable agricultural system and especially for smallholders who comprise most of the world’s farmers ( 12 – 16 ). Farm animals contribute not only a source of high-quality food that improves nutritional status but also additional resources such as manure for fertilizer, on-farm power, and other by-products, and, in addition, provide economic diversification and risk distribution ( 12, 13, 16 – 18 ). Moreover, increased efficiencies in the past several decades through genetic selection and improved management technologies has saved a large amount of resources, including water and land, and have substantially reduced the carbon footprint of animal production ( 16, 18, 19 ).

Why is animal food important?

First, animal products are an important source of high-quality, balanced, and highly bioavailable protein and numerous critical micronutrients , including iron, zinc, and vitamins B-12 and A, many of which are deficient in a large portion of the world’s population ( 10 – 12 ). Thus, moderate consumption of animal-sourced foods plays an important role in achieving a nutritionally balanced diet, especially in the developing world ( 11 – 13 ).

How does farming affect the environment?

However, sustainable farm animal production will also require a more complete understanding of their impact on the environment. For example, a report by the FAO of the UN estimated that livestock, and especially ruminants, contribute as much as 18% of greenhouse gas emissions ( 26 ), but others have suggested that this is a gross overestimate and that the actual value may be as low as 3% ( 27 ). Regardless, as farm animal production continues to increase, we need to be concerned with not only greenhouse gases but also the impact of farm animals on soil, water, and biodiversity ( 26, 28 ). We also need to better understand the specific role of animal products in the diet in the global increase in noncommunicable diseases such as type 2 diabetes, obesity, and cardiovascular disease, because noncommunicable diseases are now responsible for more deaths worldwide than all other causes ( 29, 30 ). In this regard, recent reports from the National Research Council and from the Office of Disease Prevention and Health Promotion, Department of Health and Human Services, argue strongly for renewed focus, including additional research, on these controversial and critical issues ( 15, 31 ).

What animals can be used to graze grasslands?

Fourth, ruminants such as buffalo, cattle, goats, and sheep, efficiently convert the forages from grasslands into high-quality animal products, and grazing also can promote the health and biodiversity of grasslands if managed appropriately ( 16, 19 – 23 ). This is important because grassland pastures cover >25% of the Earth’s land surface and, despite being home to nearly a billion people, comprise primarily marginally or non-arable land ( 24, 25 ).

Why is the demand for animal products increasing?

Second, because they are recognized as high-quality foods, global demand for animal products is almost certain to continue to increase dramatically ( 10, 13 – 16 ). The drivers of the increased demand for animal products include not only population growth but also increased affluence, especially in the developing world, where most of the increase in population will occur ( 3 ).

What is food security?

Food security is defined by the WHO as “… [ready] access to sufficient, safe, nutritious food to maintain a healthy and active life” ( 4 ). Although the focus of discussions about food security is usually the developing world, where most of population growth is expected to occur, food security is equally important for the developed world. Globally, food insecurity currently affects nearly a billion people, including 20 million children aged <5 y who experience severe malnutrition, and is one of the “…major causes of death and disability worldwide” ( 5 ). Similarly, in the developed world food security remains problematic; in the United States, for example, nearly 15% of households are food insecure ( 6 ).

Why is food security important?

Solving the problems and overcoming the obstacles to sustainable food security, although daunting, are not options, because food security is critical not only to national security but also to global stability ( 32 ). Feeding the world’s rapidly expanding population can therefore rightly be viewed as the main global challenge of the 21st century. Animals will play an important role in meeting this challenge.
