Animal poultry

Algae can be cultivated easily and quickly when compared to plants. They produce very high quantities of carotenoids compared to other sources (3.0 to 5.0% w/w on a dry weight basis). They contain both cis and trans isomers of carotenoids for high bioavailability and bioefflcacy, and also contain oxygenated carotenoids (xantho-phylls), which have greater bioactivity and better anticancer properties. The proteins from Dunaliella biomass can be utilized for bread and other products and whole cells can be utilized for animal, poultry, and fish foods because they are safe. ... 

Like all other animals, poultry require five components in their diet as a source of nutrients energy, protein, minerals, vitamins and water. A nutrient shortage or imbalance in relation to other nutrients will affect performance adversely. Poultry need a well-balanced and easily digested diet for optimal production of eggs and meat and are very sensitive to dietary quality because they grow quickly and make relatively little use of fibrous, bulky feeds such as lucerne hay or pasture, since they are non-ruminants (have a simple stomach compartment). 

Animal fat (AAFCO number 33.1) is obtained from the tissues of mammals and/or poultry in the commercial processes of rendering or extracting. It consists predominantly of triacylglyerol esters of fatty acids and contains no additions of free fatty acids or other materials obtained from fats. It must contain, and be guaranteed for, not less than 90% total fatty acids, not more than 2.5% unsaponifi-able matter, and not more than 1% insoluble impurities. Maximum free fatty acids and moisture must also be guaranteed. If the product bears a name descriptive of its kind or origin (e.g., beef, pork, or poultry), it must correspond thereto. If an antioxidant is used, the common name or names must be indicated, followed by the words used as a preservative. Includes IFN 4-00-409 (animal poultry fat). 

Unlike the production-oriented economic animals (poultry, swine, cattle, fish, and shrimp) pets typically are allowed to live their full life cycles, and thus experience problems of aging, including kidney, vision, backbone, and hip failures, and obesity if food intake is not adjusted to the animal s activity level. Special puppy, kitten, and life-cycle series pet foods have been marketed. 

A veterinary drug is any substance applied or administered to any food-producing animal, such as meat or milk-producing animals, poultry, fish, or bees, whether used for therapeutic, prophylactic, or diagnostic purposes or for modification of physiological functions or behavior. 

HeterocycHc amines known as aminoimidazoazaarenes are formed during thermal processing of meat of warm-blooded animals, poultry and fish by reactions of creatine/creatinine (2-118) with certain products of the MaiUard reaction, but detailed mechanisms of their formation are not yet fuUy understood. Creatine was postulated to form the 2-amino-3-methylimidazo (2-aminoimidazo) moiety of aminoimidazoazaarenes by cycHsation and water elimination, a reaction that takes place spontaneously at temperatures above 100 °C. This part of the molecule (especially its 2-amino...

Meat, milk, eggs, and other products derived from animals, including four-footed animals, poultry, and fish. 

Most poultry production, and a growing percentage of swiae production, takes place ia iatensive, confinement operations. Much of the poultry production is carried out under a system of vertical iategration ia which a producer hatches the chicks, grows them ia the producer s faciUties or ia contract facihties, provides the feed, processes the animals, and markets the product. This system of vertically iategrated production is not as common ia the swiae iadustry. 

There is no best feed composition because animals thrive on diets composed of many different types of iagredients. Swiae and poultry generally adapt readily and rapidly to changes ia ingredient composition, as long as the diets provide adequate levels of essential nutrients. Tables 2 through 6 Hst information on the nutrient requirements of various types of swiae and poultry. 

In the United States, more than 16.3 x 10 kg of human-inedible raw materials are available each year, and the rendering industry is a valuable asset in diverting these into valuable ingredients for use primarily in animal foods (4). The three largest meat packers are responsible for nearly four-fifths of aU red meat production (5) and enormous amounts of rendered meat meal and animal fat. Three broiler producers account for about 40% of the total broiler production. American Proteins, Inc. (RosweU, Georgia), the world s largest processor of poultry by-products, produces more than 450,000 t of poultry meal, feather meal, and poultry fat each year. It also produces more than 100,000 t of fish meal, fish oil, and fish products each year. Pish meal production worldwide in 1986 was estimated at 6.23 x 10 t, which with the 125 x 10 t of meat and bone meal plus 6.67 x 10 t of feather meal and poultry by-product meal (6) is the primary source of animal proteins used by the pet food industry. 

PVDE is a nontoxic resin and may be safely used in articles intended for repeated contact with food (190). Based on studies under controked conditions, including acute oral, systemic, subchronic, and subacute contact implantation and tissue culture tests, no adverse toxicological or biological response has been found in test animals (191,192). PVDE is acceptable for use in processing and storage areas in contact with meat or poultry products prepared under federal inspection and it complies with the 3-A sanitary standards for dairy equipment. 

Most of the bacteria, yeasts, molds, and higher fungi of interest for SCP production are deficient in methionine and must be supplemented with this amino acid to be suitable for animal feeding or human food appHcations. Also, lysine—arginine ratios should be adjusted in poultry rations in which yeast SCP is used (62). Human feeding studies have shown that only limited quantities of yeast such as Candida utilis can be added to food products without adverse effects on flavor (63). 

Formic acid can also be used as an antisalmoneUa additive in animal feeds, for decontamination of feed raw materials, and prevention of flock infection in the poultry industry by treatment of the finished feed. 

Chemically synthesized antimicrobials used in animal and poultry feeds include arsenicals, eg, arsanilic acid [98-50-0] sodium arsanilate [127-85-5] and roxarsone [121-19-7]-, sulfa dmgs, eg, sulfadimethoxine [122-11-2], sulfamethazine [57-68-1], and sulfathiazole [72-14-0]-, carbadox [6804-07-5]-, and nitrofurans, eg, furazoHdone [67 5-8] and nitrofurazone [59-87-0] (see Antibacterial agents, synthetic Antiparasitic agents). 

Animal Feed. In animal feeds (1—3% lecithin) lecithin is an emulsifier wetting and dispersiag agent energy source antioxidant surfactant source of choline, organically combiaed phosphoms and iaositol and Hpotropic agent. It is used ia a milk replacer formula for calves (approximately 10,000 t of lecithin ate used for this purpose) and for veal production, ia mineral feeds, poultry feeds, fish foods, pet foods, and feeds for fur-beating animals (30). 

The sacroplasmic proteins myoglobin and hemoglobin are responsible for much of the color in meat. Species vary tremendously in the amount of sacroplasmic proteins within skeletal muscle with catde, sheep, pigs, and poultry Hsted in declining order of sarcoplasmic protein content. Fat is also an important component of meat products. The amount of fat in a portion of meat varies depending on the species, anatomy, and state of nutrition of the animal. The properties of processed meat products are greatiy dependent on the properties of the fat included. Certain species, such as sheep, have a relatively higher proportion of saturated fat, whereas other species, such as poultry, have a relatively lower proportion of saturated fat. It is well known that the characteristic davors of meat from different species are in part determined by their fat composition. 

Coccidiosis is a proto2oal disease of the intestinal tract of animals that leads to severe loss of productivity and death. The development and widespread use of anticoccidials has revolutionized the poultry industry. The estimated world market for anticoccidial agents in 1989 was 425 million and this was dominated by the polyether ionophore antibiotics monensin, salinomycin [53003-10-4], n imsm [55134-13-9], la.s9locid, and maduramicin [84878-61-5] (26).
