    Information From Our Experts

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

    Q
    Is it necessary for a rooster to be present for egg laying to begin?
    A
    No, but without a rooster, all eggs will be unfertilized.
    Q
    What are the benefits of Wind and Rain® Storm™ Cattle Minerals?
    A
    Wind and Rain® Storm™ Cattle Minerals are enhanced to resist moisture even better than Wind and Rain® Cattle Minerals. Wind and Rain® Storm™ minerals shed moisture, so water finds its way through the minerals rather than sitting on top and causing clumping and spoilage, which makes feed unpalatable to cattle.
    Q
    What are some key size benchmarks to consider with heifers?
    A
    Measure the average weight on the mature (third plus lactation) animals in your herd. Heifers can be bred when they weigh 55 percent of the mature herd size. Wither height of Holstein heifers should be at least 49 inches tall to ensure proper frame. Holstein heifers should weigh around 85 percent of mature herd size after they deliver a calf and reach at least 53 to 54 inches tall at the withers.
    Q
    What does it mean if my fish quit eating?
    A
    The first sign of a problem is often a sudden decrease in appetite. If a group of fish suddenly quits eating, the cause is usually either an adverse water quality condition or disease. First, check water quality. If a water quality problem exists, rectify the problem. If fish appear unhealthy in any way (improper or erratic behavior, sores, etc.), they may be diseased. Send unhealthy-appearing fish to a pathologist for evaluation.
    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
    Are fats important in promoting horse hoof quality?
    A
    Fats are needed by the hoof to create a permeability barrier that assists in cell-to-cell adhesion, helping prevent bacteria and fungi from penetrating the horn. Horse diets containing adequate levels of fat can, therefore, be beneficial to the hoof.
    Q
    How do I keep my rabbit warm?
    A
    Make sure that while your rabbit has adequate ventilation, it is not exposed to drafts. Rabbits should have a house to go into, and if you have wire flooring in the cage, it is advisable to set a small plank or other solid item for the rabbit to sit on to avoid the cold wind coming up under its belly. With these environmental adjustments and plenty of food, your rabbit will sail through the winter with flying colors.
    Q
    What is Paylean® and what does it do for show pigs?
    A
    Paylean® is the trade name for Elanco’s ractopamine hydrochloride. Simply put, Paylean® shifts nutrients into synthesizing lean or muscle in show pigs, and away from fat deposition. Paylean® does not increase the number of muscle fibers, but rather increases the size of existing muscle fibers.
    Q
    Should I feed my rabbit alfalfa or timothy hay has a supplemental hay?
    A
    Calcium metabolism in rabbits is unique compared to other species. Rabbits are efficient calcium absorbers and excrete excess calcium in their urine. Because of this unique metabolic system, rabbits are prone to urinary stones if fed too much calcium. Therefore, when feeding an adult rabbit supplemental hay in addition to a complete diet, it is preferable to provide timothy hay to minimize excess calcium.
    Q
    What types of parameters should swine producers use or not use to evaluate their feeding programs?
    A
    Today’s highly fluctuating ingredient prices are encouraging producers to evaluate their feeding programs. The worst parameter that can be used in feeding program evaluation is feed cost per ton, which does not account for the effects on pig growth performance. A good parameter that can be used in the evaluation is the cost of feed per pound of gain. Therefore, any improvement in feed conversion can be considered as an opportunity to fight the increasing feed prices.
    Q
    Why does Purina® Gamebird Pheasant Chow® products come in medicated and non-medicated formulas?
    A
    When a health issue arises we have a number of medicated feeds available. Please contact your Purina sales person for more complete information available for each species of game bird.
