    Information From Our Experts

    Animal experts from the Purina Animal Nutrition Center share their knowledge.

    Q
    Is there a certain type of chicken feed I should use?
    A
    It is important to select a complete feed that gives your chicks all the nutrition they need. Layer chicks should receive a feed designed to help them grow at the appropriate rate into healthy and productive laying hens. Broiler chicks need a higher-powered feed designed to help support the growth that will get them to market weight in 8 to 10 weeks. Turkey chicks have much higher nutrient requirements and must have a feed that meets their exacting needs.
    Q
    What makes Purina® Accuration® a good supplemental cattle feed?
    A
    Purina® Accuration® cattle supplements not only provide balanced protein and energy, but also incorporate Intake Modifying Technology®, which enhances digestion and aims to prevent overeating by stimulating cattle to eat smaller, more frequent meals. This self-regulated eating means cattle eat just what they need, so less feed is wasted and less hand feeding is required.
    Q
    How many dairy cow herds in the U.S. have broken the 30,000 pound mark for milk production?
    A
    Of the 19,658 dairy cow herds on test reported by the four records processing centers in the country, 221 herds have broken the 30,000 pound mark. (Progressive Dairyman May 2013.)
    Q
    What is pond turnover?
    A
    Pond turnover may occur at any time of the year. However, one of the most common times is in late summer, when the water is very warm and oxygen demand is already high. Turnover is often caused by a sudden cooling of weather or a cold rain that cools the water close to the surface. The cool water on top is more dense than the warmer water below, causing the pond to turn over. Turnover often releases anoxic water from the bottom, which causes a lack of oxygen throughout the pond. This can result in a large die-off of fish. Often, by the time it is discovered, oxygen levels have already returned to normal.
    Q
    What can be done to help address urinary calculi in goats?
    A
    Delay castration until your goat is at least 4 months old, if possible; control phosphorous intake; provide plenty of water; make salt available; and feed a product that contains a urinary acidifier such as ammonium chloride. These steps will not guarantee that your goat will never have a stone incident, but they will go a long way toward trying to prevent one.
    Q
    Why is it important to measure horse feed by weight, not volume?
    A
    A 3-lb coffee can of oats is not the same amount of feed as a 3-lb coffee can of corn! The can may hold 2–3 lbs. of oats, while the can of corn may be 4–5 lbs. Further, since corn is more calorie rich than oats, the can of corn may contain 2–3 times the energy as the can of oats. Any time a horse owner changes feed, he or she must weigh the can of feed to make sure the horse gets fed the same amount of feed every meal. Plus, every different batch of corn or oats may be a different weight. A specific volume of Strategy® Professional Formula GX Horse Feed or Omolene #200® horse feed will weigh the same each time. Another option is to use a pre-measured Purina scoop, available through local Purina horse feed dealers.
    Q
    How can I keep my rabbit comfortable in summer heat and humidity?
    A
    Rabbits are unable to sweat; they can only dissipate heat by panting, but they aren’t very efficient at it, so they can easily become overheated. Rabbits will often reduce feed intake during hot weather to reduce the heat produced by the metabolism of food. Help your rabbit survive the summer by making sure it is always in the shade and has plenty of air movement around it, even using a fan. Plenty of cool, fresh water is a must. In extreme heat, put a sealed plastic bag full of ice in your rabbit’s pen. Switch gradually to a more nutrient-dense feed at the beginning of summer to help maintain production (weight gain or lactation) when rabbits reduce intake due to heat.
    Q
    Is Paylean® a steroid? Can it be used on animals other than swine?
    A
    Paylean® is not a steroid; however, it is classified as a drug by the U.S. Food and Drug Administration (FDA) and is regulated as such. Due to the rapid metabolism in Paylean®, there is no withdrawal time required. Paylean® is approved for use only in swine. Ractopamine HCl is approved for use in both swine and cattle. The cattle product is called Optiflexx® and is not approved to be fed to swine.
    Q
    Has this more stable vitamin C source been created and is it being used in small-pet food?
    A
    Modern technology has allowed us to significantly increase the shelf life of vitamin C using a stabilized version, L-ascorbyl-2-polyphosphate. The phosphate is broken off during digestion, making the ascorbic acid completely available to the animal. This ingredient is heat stable and shelf stable, making it the perfect option to ensure your pet is getting all the vitamin C it needs!
    Q
    What are some of the factors that can influence pig feed conversion (F/G)?
    A
    Feed wastage, scours, continuous flow production, pneumonia, mange, multiple source pigs and mixing pigs are among the factors that can have a significant influence on F/G. Factors with less impact include pelleting feed, antibacterial additives and genetics.
    Q
    What is the best feed to use for deer?
    A
    If you want big, healthy deer that can achieve their genetic potential for antler growth, you need a high-quality feed designed specifically for deer. Anything less will give you just that: less.
