Although recognized as important sources of functional compounds, milling by-products are often removed from the cereal kernel prior milling process. Indeed, the high presence of fiber in bran and the co-presence of lipids and lipase in germ are often considered as downsides for breadmaking. In this work, Lactobacillus plantarum T6B10 and Weissella confusa BAN8 were used as selected starters to ferment maize milling by-products mixtures made with heat-treated or raw germ and bran. The effects on the biochemical and nutritional features as well as the stability of the milling by-products were investigated.

This chapter starts with information on the overall size of the major livestock feeding operations cattle, swine, dairy cows, and poultry and their relationship to crop agriculture.
It then turns to the general economics of livestock agriculture and the structure of the livestock industry. It ends with a discussion of the economics of emissions and manure management and potential methods of livestock operation emissions control and mitigation. Livestock agriculture is concerned with raising and maintaining livestock, primarily for the purposes of producing meat, milk, and eggs. Livestock agriculture also includes wool and leather production and may include animals kept for recreation riding or racing and draft.
Department of Commerce, , Table Livestock agriculture is the market or consumer for a significant portion of U. Annual U. Corn provided Sorghum and barley added another 2 percent of cash receipts from farm marketings of crops. Hay is consumed by livestock and represented 3. Livestock agriculture is also the market or consumer for soybean meal and other oilseed meals.
Soybeans accounted for Approximately 37 percent of U. In summary, livestock agriculture directly accounts for nearly half of U. In many states, livestock agriculture accounts for more than 65 percent of cash receipts from farming.
Livestock agriculture provides the basis for the meat, dairy, and egg processing industries. Meat products represent Finally, meat, dairy products, and eggs are important components of the U.
Economic characteristics of livestock agriculture addressed here include markets and prices, production costs, and industry structure. Prices for livestock and products are determined in competitive markets. With the exception of federal marketing orders for dairy see Blayney and Manchester, , for a description of U.
Producers respond to market prices for livestock and their products and to prices of feed ingredients by increasing production following periods of high profit and decreasing production following periods of losses. Biological lags in production response are a fundamental characteristic of livestock agriculture. The gestation or hatching periods of livestock and poultry plus the period from birth to market weight or to milk or egg production impose minimum times in which livestock and poultry farmers can respond to price or profit signals.
This period approaches one year for swine and two to three years for cattle. Broiler producers are able to respond within a few months, while egg and turkey producers may require 6 to 18 months to respond.
The result of the lagged response is a cycle in production, prices, and profits as producers are constantly adjusting output by expanding or exiting production. Prices and profits in any single year may not be representative of the equilibrium price and profit of a livestock sector due to the length of cycles in prices and profits. Volatility in prices is evident. Feed cost is generally the largest component of total cost and varies directly with ingredient corn, soybean meal, hay prices.
Recent U. Department of Agriculture USDA benchmark cost series show feed to be about 60 percent of the cost of broilers, turkeys, table eggs, and pigs. Feed is more than 70 percent of the benchmark cost of weight gain in high plains cattle feeding operations.
Volatile prices for feed ingredients and market animals, combined with biological lags in production response, result in extremely volatile profit margins. Extended periods of losses sometimes severe and profits are common in the livestock sector. For example, beef cattle feedlots with more than head of cattle, which sold an average of.
The largest size categories for other kinds of livestock operations have similarly large shares of the number of animals and production.
Nevertheless, the large number of operations in even the largest size categories keeps any one, or any group, of them from having sufficient market power to affect the prices of their products. Various methods of vertical coordination between meat processing organizations and animal feeding operations AFOs are in use Martinez, Broiler, turkey, and some swine processors use production contracts.
Production contracts are generally defined as contracts between owners of livestock and independent farmers to have the farmers raise the livestock on their farms. Typical production contracts have the livestock owner frequently, but not necessarily, a processor provide livestock, feed, medication, and managerial and veterinary support, while farmers provide buildings, labor and management, land, manure management, utilities, repairs, and supplies in exchange for a fee per head or per pound produced.
Marketing contracts or agreements are another method of vertical coordination between processors and livestock producers. Marketing contracts or agreements may be defined as contracts to deliver livestock, and establish the base price and price increments for specific attributes e. Marketing contracts are distinguished from production contracts in that farmers retain ownership of the livestock and provide feed and other inputs until the livestock are delivered to the processor.
Producers of livestock and poultry compete in an international market. Beef and pork are both imported and exported. Net exports range from 3 percent of pork production to 18 percent of broiler production. Although exports constitute a relatively small fraction of total production, they add significantly to agricultural income. Increased production costs can decrease the international competitiveness of U.
A significant cost increase in the U. The number of farms in the United States peaked in at about 6. There were 1. The fraction of U. Increased specialization has accompanied increased productivity. There has been little change in the number of pigs in the United States since The number of cows being milked peaked at 25 million in and has since dropped to about 9 million. Milk production per cow increased markedly from kilograms per year in to more than 8, kiograms per year in USDA, c, d.
Annual production of livestock and products has risen steadily over the past century, although production cycles are evident in the data. Also evident is a steady increase in livestock productivity defined here as the quantity of meat, milk, and eggs produced annually from a given inventory of livestock. Productivity gains arise from an increased number of animals born and raised per breeding animal per year, increased growth rates and market weights of animals intended for slaughter, and increased milk or egg production per animal per year.
In addition to producing more from a given inventory of animals, livestock farmers have greatly decreased the quantity of feed required to produce a pound of meat, milk, or eggs. Productivity gains have been accomplished through genetic selection, as well as through improvements in diet formulation and processing, housing and environmental controls e.
Havenstein and colleagues demonstrate that a strain of broiler chicken fed a current diet requires about one-third the feed and one-third the time to produce a 4.
Since modern broilers are grown to heavier weights, the actual efficiency gains are altered. The modern broiler raised to 5. The strain required about days to produce a 4. These productivity gains are consistent with those cited by Martinez , Table 3. Note that reduced feed consumption per pound of product results in a proportionally larger reduction in the quantity of excreta on a dry weight basis.
For example, if feed consumption is reduced to 42 percent of the original quantity, and if 15 percent of the original quantity was and is retained in the product, then the dry weight excreta would be In the United States, there were 79, dairy farms with more than three milk cows reported in the census of agriculture Kellogg, In contrast to other food animal industries, the dairy industry is not.
Farms are owned and managed independently of processors. Most dairy farms raise their own replacement heifers but sell bull calves. Fluid milk is sold to processors, which may be controlled by cooperatives or by private or public corporations. See Blayney, , and Manchester and Blayney, , for further exposition of structure and trends in the U.
Beef Cattle. The number of beef cattle in the United States peaked at million head in USDA estimated that in the U. Many of these are cow-calf operations, with cattle fed on pasture, that are not considered AFOs. For example, 0. Feedlots vary in size, from a great many operations that hold only a few animals to a small number with a one-time occupancy capacity of more than , head. The cattle feeding industry has not developed integration or contractual arrangements to the extent that the poultry or swine industries have.
Most feedlots are privately held; an owner may have more than one, but ownership of a feedlot does not necessarily mean ownership of the cattle being fed there.
Custom feeding is common where an investor who owns the cattle may have no active involvement in cattle feeding or agriculture except through an investment portfolio. These operations may involve feedlots with capacities as large as 10,, head. Large commercial feedlots may have a substantial land base for feed production but in most instances would have to purchase a significant portion of the feed needed.
Custom feeding housing and feeding cattle on a feedlot for a fee; the cattle are not owned by the feedlot owner is common. Cow-calf operators who do not have a feedlot may also utilize custom feeding after their cattle have been weaned.
The proportion of custom-fed cattle within a feedlot is not necessarily related to overall size of the feedlot. It has become increasingly common for smaller farmer-feeder operations to use custom feeding as a way to decrease risk or to capitalize expansion. Almost all of the U. There were 81, farms with at least one pig on December 1, Of those, The U.
Iowa's Corn Production. Source: PRX, Jan. You wish! Less than 1 percent — or only about 3, acres of sweet corn is grown in Iowa each year. Most of the corn you see growing in Iowa is field corn, which is used to make fuel, feed, food and thousands of other everyday products. Iowa has been the king of corn for almost two decades.

In combination with the projected world population of nine billion by , further malnourishment of both humans and animals may occur; therefore, understanding of the current status of food waste and reuse is important. Large amounts of food waste meat, vegetables, fruits, and breads are produced daily. Results of the previous research suggest that food waste can be used successfully in diets of monogastric animals. The poultry industry is growing globally and uses large amounts of corn and soy for poultry diets; therefore, research should be conducted to investigate the partial use of alternative feed ingredients to meet the growing demand for poultry production.
Bioethanol is the product of fermentation of starch contained in renewable resources, such as corn, wheat, rye and rice. Research conducted in recent years has demonstrated the possibilities of corn DDG as feed for livestock due to its high content of valuable protein, high calorific value and bioelements. Distillers grain has been used as feed for beef and dairy cattle, sheep, swine and poultry. In case of ruminants, it is important that distillers grain is foodstuff high in ruminal undegradable protein, with beneficial fibre content that does not cause rumen acidosis. DDGS has positive influence on milk yield and its fat and protein content. Research on rumen fermentation has proven that DDGS positively affecs processes in forestomachs: methanogenesis, ammonia emission and volatile fatty acids profile. Reprocessing of agri-food industry by-products may well be an alternative for traditional methods of feeding animals and utilizing valuable nutrients that they contain. Frontiers in Bioenergy and Biofuels.
Food waste in animal feed with a focus on use for broilers
Many farmers already produce biomass energy by growing corn to make ethanol. But biomass energy comes in many forms. Virtually all plants and organic wastes can be used to produce heat, power, or fuel. Biomass energy has the potential to supply a significant portion of America's energy needs, while revitalizing rural economies, increasing energy independence, and reducing pollution. Farmers would gain a valuable new outlet for their products.
Use of Corn Dried Distillers Grains (DDGS) in Feeding of Ruminants
Animal feeds are classified as follows: 1 concentrates, high in energy value, including fat, cereal grains and their by-products barley, corn, oats, rye, wheat , high-protein oil meals or cakes soybean, canola, cottonseed , peanut [groundnut] , and by-products from processing of sugar beets, sugarcane , animals, and fish, and 2 roughages, including pasture grasses, hays, silage , root crops, straw, and stover cornstalks. In the agricultural practices of North America and northern Europe, barley , corn, oats , rye , and sorghums are grown almost entirely as animal feed, although small quantities are processed for human consumption as well. These grains are fed whole or ground, either singly or mixed with high-protein oil meals or other by-products, minerals, and vitamins to form a complete feed for pigs and poultry or an adequate dietary supplement for ruminants and horses. The production of grains is seasonal because of temperature or moisture conditions or a combination of both. The grain is dried to 14 percent or less moisture to prevent sprouting or molding; the grain is then stored in containers or buildings where insects and rodents cannot destroy it.

Fodder , a type of animal feed , is any agricultural foodstuff used specifically to feed domesticated livestock , such as cattle , rabbits , sheep , horses , chickens and pigs. Most animal feed is from plants, but some manufacturers add ingredients to processed feeds that are of animal origin. The use of agricultural land to grow feed rather than human food can be controversial; some types of feed, such as corn maize , can also serve as human food; those that cannot, such as grassland grass, may be grown on land that can be used for crops consumed by humans. In many cases the production of grass for cattle fodder is a valuable intercrop between crops for human consumption, because it builds the organic matter in the soil.
Ethanol can be produced from a number of different types of grains, such as corn, wheat and sorghum, as well as from agricultural waste products such as rice hulls, cheese whey, potato waste, brewery and beverage wastes and forestry and paper wastes. At present, the majority of ethanol in the U. Such carbohydrates convert into glucose more easily than most other kinds of biomass.
