The Link Between Poor Air Quality at Brooding and Disease and Poor Performance

Even though most poultry producers have specific brooding management programs, many flocks are affected by respiratory problems that can be directly attributed to a failure to follow those guidelines. The results of improper brooding management take the greatest toll later in a flock’s life, but early management is often overlooked as the source of later respiratory disease and performance declines. Learn about three basic steps to minimize disease and performance loss.

Enhancing Turkey Production through Careful House Management

The successful production of turkeys requires great attention to detail for an extended growout period. In terms of ventilation and litter management, the needs of the birds change over time as the birds mature and their body weight increases causing an increase in density in the houses. The impact of humidity and ammonia on air and litter quality remains the same though throughout the entire brooding and growout period. Improper ventilation that allows humidity to rise will cause the litter to deteriorate and more ammonia to be generated.

The Role of House Management in Antibiotic Free Operations

While ABF production is of questionable value to the birds in terms of health and welfare, and has potentially negative environmental implications due to the loss in feed efficiency, it is of increasing value to the consumer. Successful implementation of an ABF program requires several components that can intertwine with each other: Deliberate management of intestinal microflora Increased proficiency in house and litter management Decreased pathogen pressure Download our latest white paper for the full story.

Animal Welfare Initiatives in the Commercial Poultry Industry

Contrary to consumer perception, broiler’s welfare status is better than at any time in the history of modern poultry production. The advent of new technology such as solid sidewall, tunnel ventilation and automated housing provides birds with comfortable living conditions. This new technology allows for unprecedented temperature consistency, humidity control and air quality for the betterment of bird welfare. Learn how to adopt and properly implement these technologies.

PLT Effects on Turkey Production and Profitability

In this trial, turkeys grown in barns with litter treated with PLT® had consistently better average daily weight gain and average total weight than birds in the control barns on the same farm. Read more to learn about the complete study and results.

PLT Treated Poultry Litter More Valuable as Fertilizer Source

As fertilizer prices skyrocket, the value of poultry litter as a fertilizer source is being leveraged by more and more producers. Recent studies have shown how PLT®-treated litter brings the N:P ratio back into proper alignment for maximum fertilizer value. Read the entire white paper paper and contact your Jones-Hamilton Co. representative to learn how you can profit from rising fertilizer costs.

Acidification of Calf Bedding Reduces Fly Development

Environmental stressors, such as high fly density, can affect calf well-being. Sodium bisulfate (SBS) is an acidifier that reduces the pH of flooring and bedding, creating a medium that neither bacteria nor immature flies (also known as larvae or maggots) can thrive in.

Water Acidification and Broiler Performance

Beginning on page 4, two trials are detailed which study the impact of various water pHs on broiler weight gains, feed conversion, water consumption and livability. The most notable result was pH’s effect on the crop. Read the whole study to learn more.
