Abstract
Abstract A method of feeding hogs is disclosed. The method includes the steps of providing all the hogs with all the feed they care to consume for a limited feeding period of time, and thereafter denying all feed to all the hogs for a limited feedless period of time. Preferably, weaner hogs are provided with all the feed they care to consume during three separated, limited feeding periods of approximately two hours each per day. These feeding periods are alternated with three feedless periods during which all feed is denied to all the small hogs. This feeding regime is maintained until the hogs weigh approximately 100 pounds. Thereafter, two limited feeding periods are provided each day until the hogs reach market weight. In this way, hog weight gain per day is maximized and the amount of feed consumed per pound of hog weight gained is minimized. Apparatus for carrying out this feeding method is also disclosed. The apparatus includes a feed pan or trough, a high capacity feed delivery conveyor, and a timed feed shut-off means interposed between the feed trough means and the feed delivery conveyor for alternatively delivering and preventing delivery of feed to the feed trough. If desired, a water nozzle can be located above the feed trough to deliver water to the hogs during a feeding period. A timed water shut-off means can be interposed between the water nozzle and the water delivery pipe for alternately permitting and preventing delivery of water to the water nozzle.

Claim 2
Independent Claim
111 words
A method of feeding and raising hogs from the weaner stage to market stage, comprising the steps of providing all the weaner hogs with all the feed they care to consume during three separate, limited feeding periods per day, and thereafter denying all feed to all the weaner hogs for three limited feedless periods per day until the hogs weigh approximately 100 pounds, and thereafter providing all the hogs with all the feed they care to consume for two separated, limited feeding periods of time per day and thereafter denying all feed to all the hogs for two limited feedless periods of time per day until the hogs reach market weight.
Claim 3
Dependent Claim
32 words
A method of feeding hogs according to claim 1 wherein at least one feeding period extends for approximately two hours, and wherein at least one feedless period extends for approximately six hours.
Claim 4
Dependent Claim
47 words
A method of feeding hogs according to claim 1 wherein said feeding periods and feedless periods are provided for a plurality of consecutive days, and wherein said method includes the steps of beginning and ending said feeding periods and feedless periods at the same time each day.
Claim 5
Dependent Claim
22 words
A method of feeding hogs according to claim 1 wherein said feedless period is longer in time duration than said feeding period.
Claim 6
Dependent Claim
26 words
A method of feeding hogs according to claim 1 wherein each of said feedless periods is longer in time duration than any of said feeding periods.
Claim 7
Dependent Claim
29 words
A method of feeding hogs according to claim 1 including the steps of providing all the hogs with all the water they care to consume during the feeding period.
Claim 8
Dependent Claim
30 words
A method of feeding hogs according to claim 1 including the step of providing all the water to said hogs which they care to consume only during said feeding periods.
Claim 9
Dependent Claim
59 words
A method according to claim 1 including the steps of providing the feed to said hogs at a given location, providing the water to said hogs at a location above the feeding location, and collecting water spilled from the water delivery location at the hog feeding location so as to form a water-feed gruel for consumption by the hogs.
Claim 10
Independent Claim
98 words
A method of feeding hogs, comprising the steps of providing the hogs with all the feed they care to consume for not more than three separate limited feeding periods of time per day, and denying all feed to the hogs for not more than three separate limited feeding periods of time per day, at least one feeding period extending for approximately two hours and at least one feedless period extending for approximately six hours, whereby to maximize hog weight gain and minimize the amount of feed consumed by each hog per pound of weight gained by that hog.
Claim 11
Independent Claim
98 words
A method of feeding hogs, comprising the steps of providing the hogs with all the feed they care to consume for not more than three separate limited feeding periods of time per day, and denying all feed to the hogs for not more than three separate limited feeding periods of time per day, at least one feeding period extending for approximately two hours and at least one feedless period extending for approximately six hours, whereby to maximize hog weight gain and minimize the amount of feed consumed by each hog per pound of weight gained by that hog.
