Livestock animals are of great importance to the welfare of man all over the globe. They are raised and kept on for various reasons. An essential purpose of having livestock is food production and supply. The most important food products used as food for man are as follows:
This is the flesh, muscle, or flesh and the associated fat, connective tissue of slaughtered animals e.g. pork, mutton, beef, chevon etc. Meat is a very good source of animal protein in the diet of man. Moreover, animal protein is necessary for metabolic process in the body.
Milk is a white creamy coloured secretion from the mammary glands of female animals, and it is produced after parturition ( an act of giving birth). This is also a very valuable source of animal protein. Cow, Buffalo, Sheep, and Goats are a good source of milk.
Poultry eggs are products gotten from laying chickens and they are taken by man. Fortunately, it is also a good source of protein too.
Other products gotten from livestock animals are:
- Hides and Skin; for leather industries and they are also edible
- Chemical or liquid extractions form internal organs of animals; these are used in the pharmaceutical industries to manufacture hormones, medicines, and other kinds of drugs
- Animal fats; it is used for soap production; lubricating oil, and drug synthesis
- Horns and hooves; used in the industry to produce gelatin, buttons, glues, buttons, and some other items
- Manures; these are the droppings from animals and they can be used as fertilizers by farmers or for methane gas production
Intangible benefits of keeping livestock are:
- Companionship; animals can serve as a companion to man
- Income generation; we have people who raise animals to sell when matured
- Some can be used as draught animals in carrying out farm operations such as ploughing and harrowing while they can be used for house chores. Animals in this category are Cattle, Oxen, Horse, Donkey, and dog
- Some animals can be used as beast of burden to help in carrying heavy loads
- Some animals are natural weeders around our home.
Livestock animals (Cattle, Horses, Chickens, Turkeys, Pigs, Sheep, etc.) have been a huge part of human existence since the beginning of our civilization. Humans have used animals for meat, milk, eggs, labor, and clothing for thousands of years. Millions of people around the globe take care of livestock every day! (See video below)
But do we really need animal agriculture? Must innocent animals lose their lives for human benefit? Why can’t we just rely on fruits, veggies, and grains to feed and clothe the masses? Here are 10 reasons why animal agriculture exists and why it is ethical.
1. Animal Products are the Reason Most Livestock Animals are Born
The fact that humans eat and use animal products is the main reason most livestock animals are alive in the first place, even though in certain cases the process theoretically ends their lives as well. If you believe animals like cows, pigs, chickens, or sheep deserve a chance at life, you must believe in the use of animals for humans, because without us, 95% of these animals would never be born in the first place. Farmers help bring these animals into this world and give their lives meaning and purpose as they leave it (food and products). The only question that remains is whether or not the quality of life for these animals is worth them being born in the first place, which will be addressed in the subsequent “animal welfare” blogs found on the home page of our blog.
2. Livestock Infrastructure Produces Billions of Pounds of Food & Products
Meat, milk, eggs, and thousands of other food products come from animals. Animal products are found in a vast amount of foods consumed today. Furthermore, animal by-products are used extensively in almost every walk of life. While you may be able to avoid eating animal products, it is nearly impossible to avoid using animal by-products. The infrastructure of the livestock industry has allowed for thousands of these products to be made affordably, efficiently, and sustainably.
If we did away with livestock products, we would have to reinvent the infrastructure of our food supply and product supply, which would prove to be extremely costly. Thousands of farmers would have their current farming methods they have developed over centuries taken from them. Technology is what has allowed 1 farmer to feed 155 people today instead of 27 people in 1950. Livestock technology is a huge part of that. If we were to abandon animal agriculture, we would see a drastic decrease in food production and an drastic increase in food prices. This would be taking us in the opposite direction of producing enough food to feed a growing population.
3. Millions of Grassland Acres Would Go to Waste Without Livestock
Millions of acres of land are not suitable for crop production (due to slope of terrain, soil type, rainfall, etc.) and are therefore grazed by livestock animals. In fact over 13 million square miles are grazed by livestock animals around the world. These animals help maintain the ecosystem of these grass acres and convert the grass into food for humans. If we took those livestock animals away, the millions of acres of grassland would become unproductive instead of providing billions of pounds of food each year. If our goal is to feed 9 billion people by 2050, this would be a huge step backward in reaching that goal.
4. Livestock Animals Roaming “Free” Is Not Plausible
Currently there are over 11 billion birds, 87 million cattle, 67 million pigs, and 5 million sheep used in U.S. livestock production today. Farmers breed these animals, feed these animals, and protect these animals. They are domesticated. If livestock production ceased, the incentive for farmers to spend their lives caring for these animals would be gone. Farmers would no longer be there to take care of these animals, they would no longer be maintaining fences, caring for the sick, protecting them from predators, etc. Animals would either die out, live in the wild, or live in a zoo. In the wild, livestock animals would no longer be producing food, products, and labor for humans, they would become road hazards and would get into yards, gardens, and public places. They would be a nuisance. The reason these domesticated animals have survived over the generations is based on their importance to humans. Even if sanctuaries were built for large numbers of animals, only a small percentage of the amount we have today would exist.
5. Livestock Produce Vast Amounts of Fertilizer Needed to Grow Plants
Without fertilizer, farmers of all types could not grow half as much food as they do. While there are synthetic fertilizers available for farmers to use, many farmers, especially organic farmers, rely on manure from animals to fertilize their crops. Putting nutrients back into the soil through spreading of manure is one of the most natural ways to grow food without depleting the soil and the environment!
6. Livestock Food Products Provide Essential Nutrients
While it is entirely possible to consume a diet free of livestock products, it can be quite difficult. Many people in this world do not have the extra money, time, or discipline to spend avoiding products from animals. Meat, dairy and eggs contain essential nutrients such as protein, calcium, potassium, B vitamins (niacin, thiamin, riboflavin, and B6), vitamin E, iron, zinc and magnesium. Again, the infrastructure of livestock production has allowed for these products to be low in cost and easily accessed.
7. The Livestock Industry Employs Millions of People
If animal agriculture did not exist, millions of people would have to find a job doing something else. This includes jobs in animal production, processing, sales, nutrition, and health. As many know, finding a job can be a struggle no matter what industry you are a part of. Livestock farmers and ranchers have developed and passed down skills and talents over hundreds of years learning how to take care of livestock animals. Colleges and universities around the world have trained thousands of people in different areas of livestock production (see below). Abandoning all of that would be a waste of time and resources and would leave many searching for a job, possessing skills that are no longer needed.
8. The Livestock Industry is a Huge Part of the Economy
The livestock industry provides massive economic benefits to many different countries around the world. In the United States, the numbers are as follows:
- 1,851,000 jobs
- $346 billion in total economic output
- $60 billion in household income
- $15 billion in income taxes paid, and
- $6 billion in property taxes paid
Many countries are struggling economically, but agriculture is usually one of the bright spots in an economy. If animal agriculture were removed from the economy of a country like the U.S., it would be devastating.
9. Many People Rely on Animal Agriculture for Survival
Hundreds of thousands of farm families around the world rely on livestock animals for their survival. There are places where livestock animals are the only thing a family owns besides their home. In wealthier societies, we do have a choice of whether or not to eat meat, but in many places that is not an available choice.
Even in wealthy countries, livestock animals can provide the majority of a farm family’s income due to location (surrounded by pastureland), amount of land owned (not enough to make a living on crops), and climate (grow crops in the summer, livestock in the winter). Families could relocate and adapt to make a living apart from animal agriculture, but it would be unfair and extremely costly to them.
10. Livestock Animals Are a Huge Part of Our Culture
Animal agriculture is a huge part of human history and culture. Livestock farmers and ranchers view working with animals as more than a job. It is a lifestyle that is deeply ingrained in who they are and their purpose here on earth. Millions of children have been raised taking care of livestock to teach them how to do chores, develop a work ethic, and spend time with their family. You can see that in our video, “Takin’ Care of Livestock” linked here: https://www.youtube.com/watch?v=tc1X0CMDDNY&feature=youtu.be
11. Animal Food Products Taste Amazing
Although tastes and preferences vary tremendously throughout society, most people would agree that the best tasting foods involve animal products! A world without burgers, steaks, eggs, milk, and ice cream would be a sad scenario.
