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.
Laying hens need to maintain their health status, including their gastrointestinal health until at least 72 weeks of age. Gut microbiota composition is extremely important to gastrointestinal and overall health. Furthermore, the gut-brain axis enables interactions between the enteric microbiota, the enteric nervous system and the central nervous system (Dinan & Cryan, 2017). The composition of gastrointestinal microbiota can be affected by animal behavior and vice versa (Neufeld et al.,...

1. Introduction Aggressive behavior of roosters toward hens are rare in natural environments, where the two sexes form separate social hierarchies and male dominance is expressed in a passive manner [1–3]. However, it has been observed that males from broiler parental lines exhibit a high frequency of aggression toward females, especially during the display of sexual behavior [4–13]. This pattern of mating-related aggression has also been observed in slow-growing broiler...

The ancestor of the modern-day chicken, the red jungle fowl, was exposed to different spectra of light in their natural habitat (Prescott et al., 2003). The surrounding environment, vegetation, season, and time of day all affect the color of light exposure to the wild bird (Endler, 1993), which may have lingering behavioral...

In poultry farming, worms and protozoa represent the two primary classes of internal parasites that impact bird health, welfare, and productivity. While indoor-reared poultry typically avoid infestation from worms that require intermediate hosts, free-range birds are more susceptible. Interestingly, broilers tend to...

Effects of superdoses of phytase on peaking Hy-Line W-36 laying hen egg production and egg quality
Suggested link
Extensive research has investigated the effects of production systems on egg quality; however, confounding problems exist with many of the experimental designs (Chung and Lee, 2014). Insufficient consideration is given to the influence of genotype, hen age, ambient temperature and stress on egg quality. Eliminating the ambiguity created by these effects is crucial when evaluating the effect of production system on egg quality. The present study aims to identify limits to the hen age, so that...

I. INTRODUCTION Production improvements in commercial meat chickens via genetic selection and improved husbandry have resulted in rapid growing birds. These birds have endemically reduced locomotor ability; a conservative estimate is that 30% of birds in a flock are likely to have poor mobility (Knowles et al, 2008). Leg weakness has a direct impact on production due to lower bird quality, which may result in culls or condemnation of carcasses. While not well understood, early rapid...

I. INTRODUCTION In Australia, the National Animal Welfare Research Development and Extension (RD&E) Strategy is a cross-sectoral strategy under the National Agricultural RD&E Framework. Each of the livestock industries in Australia, including the egg industry, is represented by this National Strategy, which is active in identifying the key areas of importance for the welfare of livestock. Over the last four to five years, in particular, this National Strategy has consistently...

I. INTRODUCTION Agricultural industries are on the cusp of a digital revolution. Rising demand for higher yields, combined with constraints on finite resources such as land and water, has placed increased pressure on the input side of agriculture. The increased demand on agricultural outputs from an increasing global population and socioeconomic growth has intensified the pressure on the agricultural sector to produce more with less. Current projections for population growth estimate...
