Stories From Our Farm

For nearly a century at the Purina Animal Nutrition Center, we’ve been learning what helps our animals reach their full potential. And we know if it works for us, it’ll work for other people, too.
 

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 can happen if producers don’t make short-term investments in feed supplementation for their cattle?
A
High feed costs can make producers think they can’t afford to spend money on supplementation up front. However, if they don’t make the expenditure, they end up paying the price because their cows may have a reduced ability to conceive and conceive early, plus have a lower overall reproduction rate.
Q
What are some problems associated with late cow breeding?
A
Heifers bred late are often associated with increased metabolic problems at calving, such as ketosis, lower milk production and wasted feed dollars. Breeding based on the size of the heifer could help address these types of problems.
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
How does this condition impact goats?
A
Urinary calculi occur primarily in male goats, as the female ureter is short and straight, while the male ureter is much longer and has a bend in it that provides a perfect place for a stone to lodge. When the ureter is blocked the goat cannot urinate — an extremely painful and distressing condition. If not immediately treated, the goat’s bladder can rupture, and the goat will die. Pygmy goats and castrated males whose urinary tracts are underdeveloped are particularly prone to urinary calculi, as are many breeds of meat goats.
Q
Why is good dental care important for senior horses?
A
As a horse ages, the grinding motion of chewing wears the teeth down, and the teeth then erupt to replace what has worn away. At some point in a horse’s life, there is not enough tooth left to replace the wear, and the horse can no longer chew properly. Further, as the teeth wear, they can develop sharp edges or points that can lacerate the cheeks and tongue. Finally, inadequate chewing can cause lack of salivation, which may result in poor lubrication for swallowing, thus increasing the possibility of choke.
Q
Does rabbit enteritis have other causes?
A
Parasites such as trematodes (flukes), cestodes (tapeworms), nematodes (intestinal worms) and coccidia (protozoa) can also cause enteritis in rabbits. It is wise to establish a health care program with a veterinarian that includes regular checks for various parasites and a comprehensive prevention program. Coccidia are particularly ubiquitous in animal facilities and the environment in general. Outbreaks are common and can be devastating, especially in young animals. Some antibiotics and other compounds can also cause enteritis. Nitrates in drinking water can pose a problem, too.
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
How is vitamin C incorporated into the manufacture of small-pet diets, and is nutritional value lost in the process?
A
Naturally occurring ascorbic acid is highly sensitive to high temperatures, pH, oxygen, and pressure. Unfortunately, high temperature and pressure also occur during the manufacture of many animal diets. Most small animal and pet bird diets contain at least some pellets or extruded particles. Pelleting and extrusion processes generally involve some heat and pressure, although to different degrees. Because the source of vitamin C within a diet usually comes from the pellets/extruded kibble, finding a heat-and-storage-stable vitamin C source was important to the animal feed industry. Current technology has allowed us to overcome these issues and provide long-lasting diets for species requiring vitamin C.
Q
What conditions can cause heat stress in sows?
A
Sows can begin to feel heat stressed as temperatures surpass 70° F, depending upon humidity. Sows are most comfortable between 45 and 70° F; the range of 60 to 65° F is optimal for lactating sows. As temperatures increase outside of this range of comfort and humidity levels exceed 40 percent relative humidity, feed consumption can begin to decrease.
Q
What factors should wildlife managers consider in making nutrition decisions for deer and elk herds?
A
Seasonal forage availability and quality, physiological state and nutritional requirements, number and kinds of animal species, livestock and grazing management practices, and production goals.
