The animal feeds industry has known for some 25 years how to formulate a compound diet which conforms to a set of minimum or maximum nutrient constraints, and to ensure that the ingredients are chosen in such a way as to minimize the cost per ton of the resulting compound. The computer technique of lincar programming has been in use for over 10 years by the larger firms as a routine step in die...

The quantity of by-products from food processing has doubled over the last three decades in Japan. Using these by-products for animal feed would achieve a decrease in environmental pollution, as well as a reduction of the cost of animal production. By-products now constitute about 30% of the total feed consumed in Japan, and are used especially on dairy farms. Some by-products are beneficial in...

The industrialization of livestock production and the widespread use of nontherapeutic antimicrobial growth promotants has intensified the risk for the emergence of new, more virulent, or more resistant microorganisms. These have reduced the effectiveness of several classes of antibiotics for treating infections in humans and livestock. Recent outbreaks of virulent strains of influenza have ari...

Airborne microorganisms and microbial by-products from intensive livestock and manure management systems are a potential health risk to workers and individuals in nearby communities. This report presents information on zoonotic pathogens in animal wastes and the generation, fate, and transport of bioaerosols associated with animal feeding operations and land applied manures. Though many bioaero...

This review studies biofuel expansion in terms of competition between conventional and advanced biofuels based on bioenergy potential. Production of advanced biofuels is generally more expensive than current biofuels because products are not yet cost competitive. What is overlooked in the discussion about biofuel is the contribution the industry makes to the global animal feed supply and land u...

20 21 Distillers’ Dried Grains with Solubles (DDGS) is the major by-product of bioethanol and distillery 22 plants. Due to its high content of proteins, water-soluble vitamins and minerals, DDGS has been 23 long marketed as animal feed for livestock. EU legislation on liquid biofuels could raise the 24 demand on bioethanol production in Europe, with a resulting increase in DDGS availability. 25...

Nano minerals are widely used in diversified sectors including agriculture, animal, and food systems. Hence, their multiple uses provoke the production of nanomaterials at the laboratory level, which can be achieved through physical, chemical or biological methods. Every method is having its own merits and demerits. But keeping all in mind, chemical methods are more beneficial, as uniform nano-...

As consumers have become more interested in understanding how their food is produced, scrutiny and criticism have increased regarding intensified food animal production methods. Resolution of public concerns about animal agricultural practices depends on understanding the myriad factors that provide the basis for concerns. An online survey of 798 U.S. households was conducted to investigate rel...

Sustainable feed formulation (defined here as nutritional and economic feed optimization) is substantial in feed chain production from crop farmers to livestock producers. Diet formulation employing a static linear programming (LP) approach, which is widely used in trading firms and feed production facilities, does not allow for intertemporal flexibility. Our approach allows the interaction bet...

Feather keratin is highly resistant to degradation, but some keratinase producing microorganisms can easily degrade these insoluble keratins. These keratinase producing species have an important application in removal of poultry waste and recycled into valuable byproduct. Bacillus sp was screened from soil samples of slaughterhouse and poultry farm area using azokeratin medium. Highest keratina...
