Summary of Losses to Livestock and Poultry 
The estimated losses to livestock and poultry during production and 
marketing are summarized in Table 28, 
It is generally recognized that about 70 percent of the feed for 
enimals comes from cropland and about 30 percent from pasture and 
range. Of the total returns of $15,717 million in the industry, 
$11,002 million may accordingly be credited to cropland and 
$,715 million to pasture and range. Similarly, of the losses of 
$2,688 million, about $1,882 million may be considered a loss of 
cropland products, and $806 million as a pasture and range loss. 
It. is impracticable to compute acreage equivalents of livestock 
losses independently of the similar equivalents of crop losses. 
The equivalent of cropland acreage lost from animal diseases and 
other livestock losses was based on the potential production of 
United States cropland, determined as follows:

Livestock losses of $1,882 million constitute 5.55 percent of the 
total potential production from cropland. This percentage of the 
total of 357,835,900 acres of cropland in the United States is 
19,859,000 acres, the acreage equivalent of livestock losses. That 
is, the potential return from 19,859,000 acres of cropland was 
lost because of the diseases, insect pests, and internal parasites 
of Livestock and the market downgrading of livestock products due 
to quality deterioration.
