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.
1. Introduction Heat stress (HS) has undesired effects on the growth performance [1,2] and meat quality [3] of broiler chickens. During HS, chickens seek to dissipate unwanted and excess body heat by increasing panting, resulting in alteration of blood acid/base status, which in turn can give rise to respiratory alkalosis [4] and disruptions in muscle membrane integrity [3]. Additionally, the work required to maintain body temperature consumes diverts energy from metabolic...

High ammonia affects broilers in many ways. Research has shown that ammonia concentrations as low as 25 ppm can reduce bird weights at 28 days of age by two to seven percent while 50 ppm ammonia has been shown to reduce bird weights from 16 and 19 percent (F.N. Reece et. al., 1980,...

1. Introduction The population of the world is growing at exponential rates and, according to United Nation’s Revision of World Population Prospects https://esa.un.org/unpd/wpp/), it is projected to reach a number of over 9.7 billion by 2050. This population growth poses issues that may affect the sustainability of demographic, social and economic systems. More specifically, one of the main challenges consists of finding a way to feed all these people and agriculture,...

The uterine prolapse is one of the problems facing egg-producing poultry growers, whether it is eggs for hatchery or for human consumption.
In the normal situation and when laying eggs, part of the oviduct is taken out for a few moments and then return to the normal state. However, sometimes after ovulation, a reversal of that part, especially the last part of the uterus and vagina, can not return to the normal state. Which causes what is known as uterine prolapse and in severe cases...

Metro Manila (CNN Philippines, March 16) — The highly-pathogenic H5N6 avian influenza or bird flu has reemerged in the Philippines more than two years after a similar strain affected poultry in the country, Agriculture Secretary William Dar announced on Monday.
He said bird flu was detected in a quail farm in Jaen, Nueva Ecija. Testing for avian influenza was done on March 13 after 1,500 out of 15,000 quails died in a farm in Barangay Ulanin-Pitak, he said,...

INTRODUCTION It has been reported that the low locomotor activity of broilers coupled to their high initial growth rate of broilers results in leg problems and gait abnormalities. Long times spent sitting on wet litter may cause breast and leg skin lesions, which may contribute for the deterioration of the flock well-being (McGeown et al., 1999; Vestergaard & Sanotra, 1999; Weeks et al., 2000; Bokkers & Koene, 2004; Bessei, 2006). A causal interrelationship between the...
