an experiment was performed to investigate the energy efficiency and effect of poultry house size on energy productivity in 3 different capacity management systems. capacities of houses were 10000(3 housings), 20000 (2 housings) and 28000 (1 housing) birds per production period and were assigned as hi, hii and hiii respectively. this experiment was conducted in a completely randomized design ap...

Poultry housing Improvements to poultry housing systems in developing countries have focused on providing an environment that satisfies the birds’ thermal requirements. Newly hatched birds have a poor ability to control body temperature, and require some form of supplementary heating, particularly in the first few days after hatch. Many developing countries are located in tropical areas where m...

The extensive system of poultry production (commonly known as “free-range”) is based on the practice of allowing the bird access to foraging areas outside the poultry house. This system was widely practiced prior to the development of more productive strains of poultry and better management facilities (automated feeding and watering, better housing, environmental control) around the middle of t...

the study determined the willingness and capacity of poultry farmers to pay for extension services in nasarawa state, nigeria. at this research used a sample size of 120 poultry farmers. simple descriptive statistics, kuppuswamy scale and logit regression model were used data analysis. the results showed that majority of the poultry farmers (87.5%) indicated their willingness to pay for extensi...

R.M. GODS Department of Animal Science and Poultry Science, University of Natal, P.O. Box 375, Pietermaritzburg, 3200 Republic of South Africa Since poultry breeding started in earnest over 50 years ago there have been considerable environmental changes in the industry, some beneficial (improved disease control, housing, nutrition, lighting) and some deleterious (increased stocking rates, large...

acid-binding capacity (abc) of a feed is the amount of acid required to reduce the ph of feed to a special level such as 3. all poultry feed ingredients used in this study were collected from feed mills in iran. the ph and abc were determined using the standard methods in deionized and magnetized water at room and body temperatures. the ph of most feed ingredients was raised in magnetized water...

Proposition 2, which requires that egg-laying hens be confined only in ways that allow these animals to lie down, stand up, fully extend their limbs and turn around freely, was passed by the voters of California in 2008. These new housing requirements were introduced in the USA and European Union without considering the potential impact of changes in layer hen housing on the health of poultry w...
