The Effect of Intake of Garbage Fat upon Fat Content of Sow's Milk¹

University of Hawaii Agricultural Experiment Station

Abstract

Fifty-two milk samples were collected from eighteen sows during early and advanced stages of lactation. Three different rations were fed during the experiment: (1) dry concentrate only, (2) one-third dry concentrate and two-thirds garbage, and (3) garbage only. On an air-dry, equal-moisture basis the dry concentrate mixture contained 2.8 percent fat and the garbage, 27.1 percent fat.

The fat content of the milk increased with the increase in garbage (or fat) intake and with the advance of lactation. The average fat content of the milk was 6.1 percent when the sows received dry concentrate only and 9.6 percent when they received garbage alone.
