Abstract

In some embodiments, the presently disclosed subject matter provides a method of delivering a bioactive composition to ceca of a bird. In some embodiments, the method comprises (a) providing a bioactive composition; (b) delivering a treatment effective amount of the bioactive composition to a cloaca of the bird; and (c) providing stimulation to a vent of the bird; whereby delivery of the bioactive composition to the ceca of the bird is accomplished.

Claims (35)

1 . A method of delivering a bioactive composition to ceca of a bird, the method comprising:

(a) providing a bioactive composition;

(b) delivering a treatment effective amount of the bioactive composition to a cloaca of the bird; and

(c) providing stimulation to a vent of the bird; whereby delivery of the bioactive composition to the ceca of the bird is accomplished, wherein the bioactive composition contains from about one half to about one hundred calories.

2 . The method of claim 1 , wherein the bioactive composition is water or comprises a water-based solution or suspension.

3 . The method of claim 1 , wherein the bioactive composition comprises a component selected from the group comprising a prebiotic, a probiotic, a nutrient, an enteric modulator, an osmolyte, a vaccine, fiber, water, and any combination thereof.

4 . A method of delivering a bioactive composition to ceca of a bird, the method comprising:

(a) providing a bioactive composition;

(b) delivering a treatment effective amount of the bioactive composition to a cloaca of the bird; and

(c) providing stimulation to a vent of the bird; whereby delivery of the bioactive composition to the ceca of the bird is accomplished, wherein the bioactive composition has an osmotic pressure not greater than 800 milliosmoles.

5 . A method of delivering a bioactive composition to ceca of a bird, the method comprising:

(a) providing a bioactive composition;

(b) delivering a treatment effective amount of the bioactive composition to a cloaca of the bird; and

(c) providing stimulation to a vent of the bird; whereby delivery of the bioactive composition to the ceca of the bird is accomplished, wherein the treatment effective amount ranges from about 0.5 to about 7.5 mL of bioactive composition solution per kg of live weight of subject.

6 . A method of delivering a bioactive composition to ceca of a bird, the method comprising:

(a) providing a bioactive composition;

(b) delivering a treatment effective amount of the bioactive composition to a cloaca of the bird; and

(c) providing stimulation to a vent of the bird; whereby delivery of the bioactive composition to the ceca of the bird is accomplished, wherein the treatment effective amount ranges from about 0.01 to about 0.06 mL per gram of live body weight.

7 . The method of claim 1 , wherein the treatment effective amount comprises bacteria ranging from about 1×10 5 colony forming units (cfu) to about 8×10 9 cfu.

8 . The method of claim 1 , wherein the bioactive composition comprises a probiotic component and a vaccine component.

9 . The method of claim 1 , wherein the bioactive composition comprises two or more components present in a synergistically effective amount.

10 . A method of delivering a bioactive composition to ceca of a bird, the method comprising:

(a) providing a bioactive composition;

(b) delivering a treatment effective amount of the bioactive composition to a cloaca of the bird; and

(c) providing stimulation to a vent of the bird; whereby delivery of the bioactive composition to the ceca of the bird is accomplished, wherein delivering a treatment effective amount of the bioactive composition to a cloaca of the bird comprises inserting a delivery device into the cloaca for a distance sufficient to provide delivery of the bioactive composition to the ceca, wherein the distance sufficient to provide for delivery of the bioactive composition to the ceca comprises about 0.25 to about 3 centimeters (cm).

11 . The method of claim 10 , wherein the delivery device comprises a pipette or other blunt tubular device.

12 . The method of claim 1 , wherein said bird is selected from the group comprising chickens, turkeys, ducks, geese, quail, pheasant, and ostrich.

13 . A method of delivering a bioactive composition to ceca of a bird, the method comprising:

(a) providing a bioactive composition;

(b) delivering a treatment effective amount of the bioactive composition to a cloaca of the bird; and

(c) providing stimulation to a vent of the bird; whereby delivery of the bioactive composition to the ceca of the bird is accomplished, wherein the bird is treated prior to, during, and/or after transport.

14 . A method of delivering a bioactive composition to ceca of a bird, the method comprising:

(a) providing a bioactive composition;

(b) delivering a treatment effective amount of the bioactive composition to a cloaca of the bird; and

(c) providing stimulation to a vent of the bird; whereby delivery of the bioactive composition to the ceca of the bird is accomplished, further comprising repeating steps (b) and (c) one or more times.
