Swine Feeding Experiments with Cooked Residential Garbage¹

University of California

Abstract

Three trials have been run with 12 pens of 4 hogs each per trial (48 hogs per trial). These hogs were fed cooked residential garbage typical of Southern California garbage feed.

The addition of 10% barley increased weight gain in 2 trials. One pound of barley replaced 9 to 10 lb. of garbage.

In one of two trials, supplementation with chlortetracycline increased weight gain and increased feed utilization about 22%.

Increasing the level of garbage fed daily increased the daily garbage consumption and weight gain, but decreased the pork produced per ton of garbage fed.

In these experiments a ton of unsupplemented residential garbage produced from 39 to 80 lb. of pork. At the level of garbage feeding established (weighbacks approximately 40%), a ton of unsupplemented residential garbage produced 48 to 80 lb. of pork under the condition of these experiments.
