Definitions

• Animal Feed Compositions which are useful to enhance feed efficiency and promote growth.
• this invention relates to a combination of antibiotics in animal feed which provides an improvement in growth and feed utilization efficiency which is greater than can be achieved when either antibiotic is fed alone.
• the added response of the combination is novel and unexpected since each of the antibiotics have similar antimicrobial spectra.
• the animal feed compositions of this invention will contain the combination of ardacin and virginiamycin in an amount of from about 2.5 ppm to about 30 ppm of animal feed. Preferably, the ratio of virginiamycin to the glycopeptide antibiotic derivative will be 1:1.
• These feed compositions are administered orally to growing meat producing animals such as ruminants, swine and advantageously chickens-.
• the active ingredients may be used as premix formulations in which the active ingredients are distributed uniformly throughout a standard animal feed carrier. The premix or concentrate is then mixed with either a normal or a special fattening diet of the animal as desired.
• Such carriers are soybean meal, ' corn oil ground corn, barley, wheat, mineral mixtures such as vermiculites, diotomaceous earth, corn gluten meal, corn distillers solubles or soy flour.
• the premix may be in a liquid or solid form.
• the concentration of the combination of active ingredients in the premix may be from about 5% to about 75% by weight or a concentration of 100-2000 times greater than that in the complete feed composition.
• the premix is then uniformly mixed with the whole ration which is fed to the target animal.
• Such premix compositions are included in the term feed compositions as employed herein.
• the supplemental animal feeds themselves may also contain cellulosic roughage such as cellulose, hay,, straw, corn stalks, cotton seed hulls, oats, barley and cereal beans; natural oils such as animal fats, fish oils, and whole oil; vegetable oils such as soybean oil, olive, oil, sunflower oil, peanut oil, and cottonseed oil; antioxidants, minerals, vitamins, antibiotics, anthelmintics and other appropriate medicaments.

• vegetable oils such as soybean oil, olive, oil, sunflower oil, peanut oil, and cottonseed oil
• antioxidants, minerals, vitamins, antibiotics, anthelmintics and other appropriate medicaments such as soybean oil, olive, oil, sunflower oil, peanut oil, and cottonseed oil.
• the diets employed in this invention were prepared from a standard formula characteristic of poultry diets used by the broiler industry.
• the formulas meet the criteria set forth by the National Research
• Soybean oil meal ( ehulled, 48%)
• Virginiamycin and ardacin were fed until the final weigh day with Maduramicin added as a coccidiostat until Day 45.
• the birds were weighed by pen and sex at change from starter to grower (Day 21) and at end of study (Day 47) .
• Feed consumption was measured during starter, grower and finisher periods.
• Mortality was recorded daily along with, weights of dead birds. Any bird that died or was culled during the first seven days of the trial was replaced with a bird of the same sex from a holding pen of the same shipment. The weights of the dead birds were used to calculate feed efficiency. Following are the results obtained. Table ⁇
• the method of this invention comprises allowing monogastric animals such as poultry or swine, to feed ad- libitum on the supplemented rations or to be fed under pen conditions on a regular schedule.
• the supplemental feed rations are presented to the animals by methods known to the art.
• Ad libitum feeding in the pen is most convenient to increase the growth of the animal and feed efficiency of the operation.
• the animals are fed an effective but nontoxic quantity of the active ingredients sufficient to produce growth and increase feed efficiency.
