Nicotinamide riboside treatments of domesticated meat animals
Described herein are methods of increasing meat quantity and/or improving meat quality of domesticated meat animals using treatments of nicotinamide riboside. The nicotinamide riboside may be in the form of a chloride salt mixed or dissolved in a biologically-acceptable carrier. The treatments may be provided as an in ovo injection or orally administered to the live domesticated meat animal. The methods described herein advantageously increase the size and weight of the domesticated meat animals, reduce the incidences of transportation fatigue, and decrease meat discoloration over time.
1. A method of increasing meat quantity and/or improving meat quality in a domesticated meat animal, the method comprising providing to the domesticated meat animal or to an embryo of the domesticated meat animal an effective amount of nicotinamide riboside, wherein the nicotinamide riboside is provided as nicotinamide riboside chloride, nicotinamide riboside sulfate, or combined with amino acid complexes.
2. The method of claim 1 , wherein the nicotinamide riboside is provided as nicotinamide riboside chloride.
3. The method of claim 1 , wherein the domesticated meat animal is a chicken or a pig.
4. The method of claim 3 , wherein the meat animal is a chicken.
5. The method of claim 4 , wherein the providing comprises injecting a quantity of nicotinamide riboside into a fertilized chicken egg.
6. The method of claim 5 , wherein nicotinamide riboside is injected into the chicken egg at a concentration of at least about 250 mM in about 1 μl to about 1,000 μl of solution.
7. The method of claim 5 , wherein the nicotinamide riboside is injected into a yolk of the chicken egg.
8. The method of claim 3 , wherein the meat animal is a pig.
9. The method of claim 8 , wherein the providing comprises orally administering a quantity of nicotinamide riboside to the pig.
10. The method of claim 8 , wherein the nicotinamide riboside is administered at a dose of at least about 15 mg per kg of body weight daily.
11. The method of claim 8 , wherein the nicotinamide riboside is administered at a dose of at about 15 mg per kg of body weight to about 30 mg per kg of body weight daily.
12. The method of claim 11 , wherein the nicotinamide riboside is administered at a dose of about 30 mg per kg of body weight daily.
13. The method of claim 5 , wherein nicotinamide riboside is injected into the chicken egg at a concentration of about 250 mM to about 1,000 mM in about 1 μl to about 1,000 μl of solution.
14. The method of claim 5 , wherein the nicotinamide riboside is injected into the chicken egg at a depth of about 0.5 cm to about 2 cm.
15. The method of claim 5 , wherein the nicotinamide riboside is injected into the chicken egg about 10 to about 12 days after the chicken egg is laid.
16. A method of increasing meat quantity and/or improving meat quality in a chicken, the method comprising injecting a quantity of nicotinamide riboside into a fertilized chicken egg.
17. The method of claim 16 , wherein nicotinamide riboside is injected into the chicken egg at a concentration of at least about 250 mM in about 1 μl to about 1,000 μl of solution.
18. The method of claim 16 , wherein the nicotinamide riboside is injected into a yolk of the chicken egg.
19. The method of claim 16 , wherein nicotinamide riboside is injected into the chicken egg at a concentration of about 250 mM to about 1,000 mM in about 1 μl to about 1,000 μl of solution.
20. The method of claim 16 , wherein the nicotinamide riboside is injected into the chicken egg at a depth of about 0.5 cm to about 2 cm.
21. The method of claim 16 , wherein the nicotinamide riboside is injected into the chicken egg about 10 to about 12 days after the chicken egg is laid.
22. The method of claim 16 , wherein the nicotinamide riboside is provided as nicotinamide riboside chloride.
23. A method of improving meat quality in a pig, the method comprising orally administering nicotinamide riboside to the pig a dose of at least about 15 mg per kg of body weight daily for at least 7 days, wherein after the administering for at least 7 days, the pig has one or more of the following characteristics as compared to an untreated pig:
less Longissimus lumborum surface metmyoglobin accumulation;
less meat visual panelists' surface discoloration;
more metmyoglobin reducing ability; and/or
greater NAD+ content.
24. The method of claim 23 , wherein the nicotinamide riboside is administered at a dose of at about 15 mg per kg of body weight to about 30 mg per kg of body weight daily.
25. The method of claim 23 , wherein the nicotinamide riboside is administered at a dose of at least about 30 mg per kg of body weight daily, wherein after the administering for at least 7 days, the pig has one or more of the following characteristics as compared to an untreated pig:
better average daily gain;
larger loin eyes; and/or
increased semitendinosus muscle NAD+ levels.
26. The method of claim 23 , wherein the nicotinamide riboside is provided as nicotinamide riboside chloride.
