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.
During IPPE 2022 in Atlanta, Edgar Oviedo-Rondón (North Carolina State University) talked about two projects where they worked together with companies to improve their decision-making process by using data.

Poultry farms act as an important source of transmission of antimicrobial-resistant (AMR) Salmonella to the environment as well as to humans. Indiscriminate and prophylactic use of antibiotics in poultry farms is one of the reasons behind it. Therefore, a cross-sectional study was conducted to determine the prevalence of Salmonella in broiler chickens, farm environments, as well as farmers to identify the risk factors for Salmonella colonization in broiler farms....

Introduction Brazilian egg production is based on intensive farming systems, which ensure greater yield in a smaller physical space. However, it favors the development of arthropod pests, such as the red mite Dermanyssus gallinae (De Geer) (Acari, Dermanyssidae). This mite feeds on poultry, causing weight loss, reduced egg production, blood spoliation anemia and, in more severe cases, death. Studies have shown that the red mite can carry Escherichia coli, Salmonella and...

A study was conducted to determine the effects of crude protein (CP) reduction with amino acid (AA) balanced diets on growth, carcass yields, litter characteristics, and ecological footprint of feeds in mixed-sex broilers. A total of 2,688 Cobb MV × 500 FF broilers were allotted to 4 treatments (14 replicates of 48 birds per pen) from 11 to 36 d of age reared in an open-sided barn. Dietary treatments included: 1) Control diet (C) with DL-Met+L-Lys+L-Thr, 2) C+L-Val 3) C+L-Val+L-Ile and...

It may be difficult to comprehend, but water actually doesn’t “flow” in drinker lines...it slowly drifts. In a way it is more appropriate to consider the flow of water in drinker lines as a pond more than as a rushing river. This holds true for a house with day-old birds or even market-age birds. Drinker line flow rates are fairly easy to calculate. For instance, a flock of 50-day-old broilers will consume roughly 85 gals/1,000 per day (Watkins, 2009). If there are...

Ethiopian scientists evaluate three promising chicken breeds in rural and small-scale systems
Improving food security around the world means boosting protein production in ways that work best for local farmers. In Ethiopia, the government and outside agencies have promoted exotic, higher-yielding chicken breeds. Unfortunately, most exotic breeds introduced in the country require a level of investment in feed, veterinary...

Introduction The world economy is experiencing an exceptionally strong but highly uneven recovery. Global growth is set to reach 5.6 % in 2021- its strongest post-recession pace in 80 yearsin part underpinned by steady but highly unequal vaccine access. Growth is concentrated in a few major economies, with most emerging market and developing economies (EMDEs) lagging: while about 90% of advanced economies are expected to regain their pre-pandemic per capita income levels by...

INTRODUCTION The storage of hatching eggs is a common routine in hatcheries and varying in duration depending on hatchery capacity and the demand of day old chicks (Gharib, 2013). In some cases, the need of extending the period of storage more than seven days may takes place. Hatching eggs are stored, generally, to minimize transport cost or to collect enough eggs for high capacity incubators. Egg storage for more than 7 days deteriorated the egg white, increased embryonic...

Calculating a proper stocking density will determine the maximum farm profitability in broiler chickens. Choosing the stocking density implies knowing the impacts on live performance, and its interrelations with the environment and dietary nutrients. Abundant studies about stocking density run under non-commercial conditions might not indicate the best reliable information to know the farm profitability. As a result, few studies are reliable for commercial purposes. Poultry managers should...

Heat Stress in Laying Hens Heat stress is one of the primary concerns for laying hen production in the summer as heat waves may significantly increase flock mortality and reduce egg production in hen houses. The use of mechanical ventilation and cooling cells are popular cooling methods used in the southern US, including Georgia. However, most of the layer farms in the US Midwest (where over 50% of US table eggs are produced) do not have evaporative cooling systems due primarily...

Bacterial chondronecrosis with osteomyelitis (BCO) is an infective leg condition that results in lameness, affecting meat chickens internationally. BCO can be induced using mechanical challenges such as wire ramps (Wideman 2016). Based on a study wherein perches had a negative impact on bird latency to lie (LTL) at 42 days (d) old (Phibbs et al. 2020) perches may be a mechanical challenge to birds also, reducing their leg health in a similar way to Wideman’s ramps. This study compared...

I. INTRODUCTION Maintaining vegetation on free range farms with fixed ranges is a significant issue (Singh et al., 2017). Nonetheless, free range accreditation programs stipulate palatable vegetation to be available on the range at all times (RSPCA 2015). This is more problematic to achieve during dry seasonal conditions and drought, which are common features of the Australian climate. ...

Free-range layer pullets are typically reared indoors within Australia, but adult layers go outdoors which might cause poorer adaptation due to the mismatch between rearing and laying environments. Indoor enrichments may optimise physical development of pullets and subsequent welfare as adult free-range hens (Campbell et al., 2019). In the outdoor environment, hens may have greater opportunities for exercise and natural behaviours which might contribute to improved physical health and...
