Poultry welfare
Proper animal welfare involves providing the proper housing, management, nutrition, disease prevention and treatment, responsible care, humane handling and, when necessary, humane euthanasia. These factors allow for the most optimal and humane growing environment. The concept of animal welfare includes three elements: the bird’s normal biological functioning, its emotional state and its ability to express its natural behaviors. Improving animal welfare can be accomplished through offerings like poultry feed enrichment, which can reduce stress, thereby increasing performance, productivity and profitability. Animal welfare is currently a major requirement for intensive poultry production. Beak trimming, stocking density, free access to feed, heat stress, and air pollutants became important issues, which are regulated in several countries. Animal welfare is observed by watching how birds naturally behave and even by looking at mortality stemming from aggressive behaviors.
Windrowing has become a very popular method of managing litter between flocks. In order to get the most benefit out of windrowing, the litter needs to be relatively damp. How damp? Ideally, the litter moisture content would be between 25 and 35%. At this level of litter moisture, when you grab a handful of litter and squeeze it, it would...

Northern fowl mites (Ornithonyssus sylviarum) are one of the more common ectoparasites (external parasites) that can be present in a flock. These mites live on their host throughout their life and feed on poultry blood. They are most commonly found around the vent, tail, and breast of the birds. Although these mites prefer poultry as a host,...

1. Introduction The consumption of poultry meat has shown an increase from 2016 (116,845.36 thousand metric ton) to 2018 (120,884.63 thousand metric ton) [1]. Moreover, during the period 2020–2029, global livestock production is expected to expand by 14%, poultry remaining the fastest growing meat accounting for about half of the projected increase in total meat output, while world population is expected to grow only by ca 1% per year [1]. The goal of the poultry...

Environmental factors encountered during pre-natal life influence the developmental trajectory of a developing embryo, altering post-natal phenotypes (Du et al., 2015). Maternal nutrition and stress directly influence the maternal environment, with both factors prominent in the broiler breeder industry. Broiler breeders are feed restricted to improve reproductive output; however evidence suggests hens suffer from chronic stress due to prolonged hunger (Mench, 2002). Feed restriction in...

INTRODUCTION Campylobacter spp. is well recognized as the leading cause of bacterial foodborne diarrheal disease and poses a serious economical and health risk globally (Skanseng et al., 2010; Silva et al., 2011; Meunier et al., 2015). The most common route of campylobacteriosis infection in humans is the handling or consumption of contaminated poultry meat (Lee and Newell, 2006). Campylobacter spp. is a commensal organism found in cattle, sheep, swine, wildlife, and domestic...

Eggshell quality can be affected by multiple factors. This article focuses on eggshell problems derived from calcium deficiency and heat stress , a frequent problem during warm seasons. The eggshell is mainly composed of calcium carbonate, and it is estimated that a laying hen secretes approximately 600 grams of calcium during its laying period to form the eggshell, which is thirty times the amount of calcium present in its body. This fact shows the high calcium...
