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.
Introduction In late years, genetic studies on broiler chickens for selection of traits such as high growth rate and larger size of the body shows there is a negative correlation between reproductive traits and increasing yield. So that's in the roosters, physiological disorders like decreased libido, decreased mating numbers and reduced sperm production have increased (Dawkins and Layton, 2012). In addition to the strong negative genetic correlation between productive and...

Introduction Crossbreeding is a method of genetic improvement [1]. It produces chickens that will be better in different economic traits, such as growth rate, feed efficiency, age at first egg, and carcass characteristics [1,2]. The superiority of crossbreeds over purebreeds in some of the above-mentioned productive and reproductive traits was confirmed by many scholars [3]. Many scholars evaluated the assessment of reciprocal crossbreeds for different breeds in different...

1. Introduction The Ethiopian indigenous chickens are characterized by slow growth, late maturity and low egg production performance which are estimated at 60 small eggs with thick shells and a deep yellow yolk color (Yami and Dessie, 1997; Niraj et al., 2014). Local chickens kept under the intensive management systems are inferior to exotic stock in health status and they are also slow in rate of feathering and exhibit recurrent outbreaks of disease (Solomon, 2004). Because of...

Introduction The improvement of genetic selection and management practices are increased dramatically for the last decades (Kryeziu et al., 2018), stocking density of broilers is one of the major factors that can improve performance to face the improvement of genetic selection (Simsek et al., 2011). Stocking density has a significant impact on production cost, however, excessive density may affect broiler performance and thus slaughterer traits. Slaughter traits are...

Poultry producers maintain healthy, productive flocks by carrying out depopulation when hens reach 65 to 90 weeks old. Depopulation means hens need to be caught, carried and put in crates on their way to slaughter. The challenge is that hens in commercial systems are not used to being handled, and they often struggle to avoid being caught. As a result, each step of the depopulation process comes with a risk of injury and stress for the...

Are rice paddies and duck operations a match made in heaven? In a recent Poultry Science ® study, researchers with Yangzhou University investigated the effects of integrating ducks into a rice farming system on duck carcass traits, meat quality, amino acid, and fatty acid composition.
The team found that a rice-duck (RD) farming system improved the carcass traits, intramuscular fat, essential amino acids, and polyunsaturated fatty...

Poor leg health in Australian fast growing meat chickens is a major welfare issue, resultant from long-term genetic selection for bird size and growth rate (Bessei 2006). Anecdotal evidence and preliminary data suggest perches may have the potential to improve leg health, decreasing the prevalence of associated leg disorders and lameness (Groves and Muir 2013). The following study sought to assess the potential role of perches in improving leg health in the context of Australia’s fast...

Providing an optimal light program during pullet rearing and breeder production starts with understanding how chickens are stimulated by light. Light intensity, light coloring and day length all play a major role in preventing or stimulating sexual maturation. Ideal day length for rearing pullets is 8 hours to prevent early sexual development and therefore assure that flocks begin lay and maintain egg production in a more uniform manner....

France and Germany are now calling on other EU countries to follow their lead in banning the controversial practice of culling male chicks, which both countries have pledged to end from January 2022.
It is “a big step forward” that French citizens have been waiting for for a long time, tweeted French Agriculture Minister Julien Denormandie, announcing the country’s ban on culling male chicks from 2022. Together with Germany, France will thus be “the first...

1. Introduction Poultry producers started to raise their commercial chickens indoors as of the 1950s for better disease control, protection from predators, and to integrate their management measures for the production of uniform products [1]. Modern breeding plans and conventional raising systems have enabled mankind to produce broiler chickens with more than 2kg body weight in 35 days [2]. Although the selection for higher growth rate and slaughter yield has dramatically...

I. INTRODUCTION In Bangladesh, duck flock management is practiced using two systems: viz. stationary and nomadic. ‘Nomadic ducks’ are those which scavenge in post-harvest paddy fields during the day and stay in temporary enclosures or tents overnight near the scavenging area (Henning et al., 2012). Stationary or household ducks are kept overnight near the farmer’s house; they travel only over short distances and are often reared by families in subsistence...

I. INTRODUCTION Feed efficiency (FE) is an important production trait in poultry. A commonly used measure of efficiency is feed conversion ratio (FCR), which is defined as feed intake (FI) per unit of egg mass (EM) in laying hens. It is widely recognised that behaviour is an important aspect of the physiological status of animals (Pennisi, 2005). Feeding behaviour may reflect animal meal habit as a potential predictor of FE (Schwartzkopf-Genswein, 2002). With the help of...
