Poultry management
Poultry management usually refers to the husbandry practices or production techniques that help to maximize the efficiency of production. Sound management practices are very essential to optimize production. Scientific poultry management aims at maximizing returns with minimum investment. A carefully controlled environment that avoids crowding, chilling, overheating, or frightening is almost universal in poultry farming. Cannibalism, which expresses itself as toe picking, feather picking, and tail picking, is controlled by debeaking at one day of age and by other management practices. The feeding, watering, egg gathering, and cleaning operations are highly mechanized. Birds are usually housed in wire cages with two or three animals per cage, depending on the species and breed, and three or four tiers of cages superposed to save space. Cages for egg-laying birds have been found to increase production, lower mortality, reduce cannibalism, lower feeding requirements, reduce diseases and parasites, improve culling, and reduce both space and labour requirements.
Alternative poultry production, particularly pasture-based production, offers opportunities for producers interested in boosting incomes, diversifying operations, and providing a specialty product for consumers. A day-range system was implemented in this study using portable net fencing around a house to make multiple camps allowing chickens access to fresh sites weekly similar to the "Yarding" system used by a majority of rural South Africans. The study was conducted to evaluate the...

The Maslow pyramid as prediction tool for market conditions As proposed by Abraham Maslow in his 1943 paper 'A theory of human motivation', the stage of moral development changes the needs of humans. The first level covers basic physiological needs for survival, like air, water and food. In the second level of safety needs, one starts to care about his personal and financial security, as well as his health and...

Dear Users, This is an interesting forum from our Spanish community, generated by Marco Antonio Hurtado Orellana from Ecuador: I am a poultry farmer in a hot area in Ecuador, with temperatures of 36 degrees and relative humidity of about 90 at critical moments. My breeding density is 8 birds per square meter, and I use fans to move air in the shed. I have reference techniques, such as subjecting to high temperatures (38 degrees) in the first two days, or take vitamin C at...

Many studies are carried out under perfect husbandry conditions within experimental research farms, i.e. individual housing or small pens with good access to feeding and drinking equipment (less competition for feed and water), climate controlled ventilation (no temperature stress or accumulation of ammonia) and clean cages with wire floors or good litter condition (less infectious challenge pressure from disease). However, field conditions are typified by a...

The chicken meat quality on the market is increasingly valued by consumers. The achievement of the physical integrity of animals during transport and slaughter is claimed by associations of animal welfare. Many authors have reported that the transport conditions and slaughter can lead to significant economic losses and negatively affect the sanitary quality of products (Gregory, 1992; Berri, 2000; Nunes, 2004). In several species of poultry, there has been trauma...

There are several reasons that can explain the fact that the majority of the weights are systematically inferior to the average weight of the flock. During a technical visit to a broiler farm the topic of uniformity is generally assessed visually and subjectively, as to do the job properly would require individual weighing of hundreds of broilers (in the absence of automatic weighers). The level of uniformity basically...

I am an engineer. 20 years ago I set up a goal to create an ideal incubator. Having studied specialized literature on incubation, I came to the conclusion, that natural incubation conditions are ideal for the development of embryo, and I decided to make an experiment. For a period of three months I set broods and in parallel installed the incubator. In April, the ratio of hatching among broods was 9% higher than the incubator. In May, it was 5% higher, in June, when the temperature was over...

Summary The quantity of reward in a Y-maze preference test refers to the period of time the animal is allowed contact with the chosen resource. Fifteen hens (Hy-Line Brown strain) were given eight preference test trials (conducted on alternate days) for their choice between dust (a tray of peat moss) or social contact (the presence of a familiar subordinate hen). The quantity of reward for social contact was 5 minutes for all birds. However, the...

Although the major supply of eggs and poultry meat in the U.S. is produced by commercial producers, many people prefer to produce their own. A variety of reasons can be given for home production, not the least of which is the desire to care for and be around growing animals. Chickens can be raised in a small area and require a minimum of daily care. However, anyone considering small flock production must look at a variety of elements before arriving at a...

In Arkansas, production agriculture is a $4 billion annual industry, three-fourths of which comes from livestock, mainly poultry (EPA, 1998). Modern production agriculture is increasingly regarded as a major source of air pollutants. The trend toward larger and more concentrated animal production coupled with the general public's increasing intolerance of odors mandates the control of odors, gases, and dust.

Poultry producers in the United States have to deal with numerous issues in the day to day operation of their facilities. One important issue is the disposal of their daily mortality. Several options are available to poultry producers, including: burial, incineration, rendering, and composting. Available options are becoming more restrictive with rising processing costs and continued concerns of environmental safety. The objective of this broiler tip is to inform readers of the viability of...

Modern broilers grow at an extremely rapid rate and convert feed to meat with exceptional efficiency. However, this rapid growth rate and conversion efficiency have been associated with an increased susceptibility to heat stress. While a variety of genetic, nutritional, feeding and environmental strategies have been examined, much of the burden for dealing with the effects of heat falls to the producer and, in turn, the housing environment (Linn et al., 2006).
