AGRIBUSINESS: HOW WATER IMPACTS POULTRY HEALTH.

Water is very essential in the poultry value chain,as its the major medium used for feeding, vaccination and cleaning. Water has also been noted as a source of infection and disease transmission,hence water safety must be part of bio security protocol for poultry health. Broiler growers move further away from using antibiotics, the importance of keeping a clean water system will continue to increase; Dr. Susan Watkins, a professor and extension specialist at the University of Arkansas, said keeping a clean water supply is a major contributor to having a healthy, successful flock. Watkins, who has been studying and speaking on the importance of clean water for years, explained how growers can keep their water supply clean at the Midwest Poultry Federation Convention in St. Paul, Minnesota, on March 16. Watkins said the keys to keeping a clean water supply are: 1)knowing the water supply’s challenges and addressing them properly, an inadequate cleaning is a waste of time and effort 2) Using downtime effectively and using that time to clean water systems 3) Using a daily water sanitizer best suited for the operation that is compatible with water, easy to use, ease to monitor and cost effective for the farm. 4) Establishing a program to monitor and verify water quality. Watkins offered up a few promising methods and new products as well as tips on how best to use them to help farmers decide which water cleaning program is best for their farm: A) Chlorine for water sanitation Watkins said chlorine is a good daily water sanitizer, but it is not perfect. The halogen is available in a variety of forms and is an effective water sanitizer, however its effectiveness is affected by numerous factors such as the pH level of the water, the temperature of the water, the cleanliness of the water, the amount of time the chlorine is present in the water, and the age and storage condition of the chlorine product. While it’s an effective antimicrobial, it does not remove all harmful microbes in the water supply. She said chlorine solutions work best in pH 4 to 7. The acidic form of chlorine, which exists in lower pH water, is a better sanitizer overall. As chlorine reacts with organic compounds in the water system, it can give off strong odors of chlorine. Watkins said the smell goes away as the chlorine sanitizes the water. Chlorine is not the best choice for areas where chloride levels are already high. B) Alternatives to chlorine Watkins said there are a few options other than using chlorine to sanitize water: hydrogen peroxide and a newer product that uses ultraviolet light. Hydrogen peroxide can be a good alternative to chlorine and works especially well for sanitizing pond or river water. Like chlorine, hydrogen peroxide can be dangerous to store, and its effectiveness declines over time. Watkins said a newer product, the Silver Bullet, from Colorado-based Silver Bullet Water Treatment L.L.C., is promising. She said the product uses ultraviolet light and continuously infuses electrolyzed air into the water supply -- what the company calls an advanced oxidation process to leave a small amount of hydrogen peroxide in the water.“I love this concept because you can just continuously treat water and not over treat it,” Watkins said. Watkins said environmental factors like mold can reduce the effectiveness of the Silver Bullet – and other sanitizers – and because the product does not leave behind a residual amount of an active compound, the only way to gauge its success is microbial monitoring before and after use. She recommended using the diffuser in a holding tank or wellhead rather than with flowing water. Cleaning considerations are important to achieve aim of sanitized water,these tips are important and helpful:1) Use the right concentration of a cleaner and give it the proper amount of time to work. Improper cleaner concentration or not giving it enough time to work will result in failure. 2) The entire system must be cleaned: the water lines, standpipes, regulators and distribution pipes. If any part of the system is not cleaned of biofilm and other residue, it can undermine all the time and effort spent on cleaning and lead to health problems in a broiler flock. 3) Document which products work best for your operation. Watkins said no two farms are the same, so it is necessary to figure out which products work best and record it for future reference. Swabs of microbial content collected before and after cleaning can help determine which products work best. No matter how well the system was flushed clean: flush it with a sanitizer birds can drink after cleaning. Stabilized products work best because they keep working for days after application. The secondary treatment can kill microbes that survived the line cleaning. Excerpts from Wattagnet.com

FEEDING OUR ANIMALS.

The saying you are what you eat holds true for you and your animals.Animal husbandry is basically to produce animal products for growth ,development and profit, hence the management of this animals is such that they reach the appropriate market weight and reach maximum productivity.This has led to a lot of management techniques that gets the animal/products to the market but the consumers bear most of the brunt . Animals are fed medicated feed because of pathogenic bacteria,some of these bacteria develop resistance ,multiply and spread to their products and invariably to those that consume them. The livestock farmers also give growth promoters to their animals to enhance rapid growth and productivity,while the animals reach market size within a shorter time,the residues of these are consumed in the animal products ; this has been linked to early sexual maturity,obesity and certain hormonal dysfunction in children. Animals have intestinal bacteria,but instead of giving medicated feed, proper management practices and balanced nutrition will be a better way to secure intestinal health of animals and also preventing infection in man. ANIMAL HEALTH= HUMAN HEALTH : YOU ARE WHAT YOUR ANIMALS EAT. The pictures shows the chain reactions that results from resistance to antibiotics.( thanks to C.D.C) http://rpc.icerocket.com:10080
