Feeding methods and systems for young livestock animals using sensory compounds
Methods of feeding young animals involves mixing sensory compounds containing botanicals, essential oils or both with at least one of a milk replacer and/or starter feed and providing the feed to the young animals to reduce feed refusal or intake variation. A method of reducing feed intake variation in a group of young animals includes feeding an effective amount of sensory compounds containing licorice root in at least one of a milk replacer or a starter feed to reduce feed intake variation compared to a group of young animals fed the same diet but without the sensory compounds. Reducing feed refusal in a young livestock animal may also include feeding an effective amount of sensory compounds in one or more of a milk replacer and a starter feed such that the young animal reduces feed refusal compared to a young animal fed the same diet but without the sensory compounds.
1. A method of decreasing refusal of a liquid milk replacer by a young animal prior to weaning, the method comprising:
feeding the young animal sensory compounds prior to weaning, the sensory compounds comprising licorice root in an amount sufficient to decrease refusal of the liquid milk replacer with which the sensory compounds are mixed compared to a young animal not fed the sensory compounds prior to weaning, the licorice root accounting for at least about 60 percent of the sensory compounds,
wherein the young animal ingests the sensory compounds at a rate of at least about 0.17 grams on a dry basis per day.
2. The method of claim 1 , wherein the young animal ingests the sensory compounds in milk replacer at a rate of up to about 11.50 grams of the sensory compounds per day.
3. The method of claim 1 , wherein the milk replacer is fed at a rate of at least about 0.75 pounds on a dry basis per day.
4. The method of claim 1 , wherein the young animal ingests at least about 0.34 grams of sensory compounds per day for a first time period and ingests a reduced amount of sensory compounds per day for a second time period following the first time period.
5. The method of claim 4 , wherein the first time period is at least about 28 days.
6. The method of claim 4 , wherein the second time period is about 7 days.
7. The method of claim 4 , wherein the reduced amount of sensory compounds comprises at least about 0.17 grams per day.
8. The method of claim 1 , wherein the sensory compounds further comprise vanillin.
9. A method of decreasing refusal of a liquid milk replacer by a young animal prior to weaning, the method comprising:
feeding the young animal sensory compounds prior to weaning, the sensory compounds comprising licorice root in an amount sufficient to decrease feed refusal of the liquid milk replacer with which the sensory compounds are mixed compared to a young animal not fed the sensory compounds prior to weaning,
wherein the young animal ingests the sensory compounds such that at least about 0.102 grams of licorice root on a dry basis are ingested by the animal per day.
10. A method of decreasing refusal of a liquid milk replacer by a group of young animals prior to weaning, the method comprising:
feeding the group of young animals sensory compounds prior to weaning, the sensory compounds comprising a licorice root sensory compound in an amount sufficient to decrease feed refusal of the liquid milk replacer with which the sensory compounds are mixed relative to a group of young animals fed the same diet but which is free of the sensory compounds prior to weaning,
wherein the young animals ingest the sensory compounds such that at least about 0.102 grams of licorice root are ingested per animal per day.
11. The method of claim 10 , wherein the young animals ingesting the sensory compounds exhibit an increased rate of weight gain compared to the group of young animals fed the same diet but which is free of the sensory compounds.
12. The method of claim 10 , wherein the young animals reduce their feed variation compared to the group of young animals fed the same diet but which is free of the sensory compounds.
13. The method of claim 1 , wherein the liquid milk replacer comprises a non-milk soy protein.
14. The method of claim 1 , wherein the milk replacer is fed at a rate of at least about 1.8 pounds on a dry basis per day.
