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.
by Sam Shafer We know that young geese benefit from warmer drinking water, but what is the optimal water temperature? Poultry scientists take a closer look     A new investigation into goose health suggests providing drinking water that is at least 18? (64.4?) may boost the activity of digestive enzymes, promote intestinal development, increase water consumption, and even increase goose eye temperature. Based on their findings, the...

Free-range commercial layer farming in Australia has been increasing for the last decade in response to consumer demand for free-range eggs. To meet this demand, there is a focus on research to optimise free-range system design and management. A range of external factors have been shown to impact hens’ daily outdoor range use including weather conditions, time of day, season and range enrichments (Richards et al., 2011; Larsen and Rault, 2021). Sunlight intensity and ultraviolet...

Visual assessments for health and welfare of broiler flocks are regularly performed by farm staff walking through the shed. However, common welfare indicators like footpad dermatitis and hockburn require manual handling of the flock and an automated measurement is desirable. There is potential for automated camera monitoring to complement human inspections for detection of health and welfare conditions and perform additional flock monitoring tasks. A proof-of-concept machine vision system...

by Sam Shafer Poultry scientists investigate microbial presence in low and high stocking densities     As consumer demand for eggs from “free range” chickens grows, a big question lingers: what is the best stocking density for chickens in free range conditions? Now a new study in The Journal of Applied Poultry Research provides important data on how free range stocking density affects the risk of spreading...

CHOLINE AS A NUTRIENT: BASIC FUNCTIONS Choline is an essential nutrient in most livestock species. It plays a crucial role in neurotransmitter synthesis (acetylcholine), cell membrane signaling (phospholipids), myelin synthesis and lipid transport (lipoproteins).   Choline is a precursor of phosphatidylcholine, a phospholipid that besides being part of the composition of cell membranes, is involved in the generation and composition of bile secretions; therefore,...

Elizabeth Doughman (WATT Global Media) talks to Sam Shafer (PSA) about poultry welfare during transportation. In this episode of Let's Squawk About It, they discuss how truck sensors are giving insights into the temperature, humidity, and other environmental conditions of the vehicle where poultry are kept during transportation. The system notifies key stakeholders, including the driver, in the event there are complications....

While summer spells fun for most of us, it’s a little different for our poultry animals such as broilers and laying hens. High temperatures cause drops in production, dehydration and heat stress which may lead to more problems like foot pad dermatitis, respiratory symptoms, shell quality problems and even death. So let's take extra care to ensure poultry welfare by providing them with easy access to clean water, shade, and proper ventilation to prevent heat exhaustion. Make sure to monitor...

Piling is an abnormal behavior commonly observed in commercial laying hen flocks. Piling occurs when birds crowd together, usually on top of one another, in a densely packed manner. A piling event may or may not end in smothering. Smothering occurs when one or more birds die due to suffocation from piling. Piling and...
