Cost Methodology Report for Swine and Poultry Sectors
Posted in: Production by admin on | No Comments
The Clean Water Act authorizes the United States Environmental Protection Agency (EPA) to
develop technology-based effluent limitations guidelines and standards (ELGs) for the control of
pollutant discharges from point source categories. Certain animal feeding operations (AFOs) are
defined as point sources. The existing ELG for the Feedlots Point Source Category (40 CFR Part
412) covers these point sources. Section 301(d) of the Clean Water Act directs EPA to
periodically review existing ELGs and revise them when necessary. As part of the EPA-U.S.
Department of Agriculture (USDA) national unified strategy to minimize the water quality and
public health impacts of AFOs, EPA is reviewing the Feedlots ELG and expects to revise the
existing effluent guidelines covering AFOs. This overview addresses the methodology for
estimating potential compliance costs for the swine and poultry (turkey, laying hen, and broiler)
sectors of AFOs.
The initial steps in the process of estimating potential compliance costs for the swine and poultry
sectors include gathering and analyzing data on swine and poultry AFOs to establish a baseline
picture. The baseline includes the amount of manure and wastewater produced, the pollution
control and management practices in place, current land application practices, and current state
requirements. Based on these data, EPA identifies possible new regulatory requirements that
may be imposed through revision of the ELGs. These new requirements are typically grouped
into several possible regulatory options. These regulatory options sometimes specify a limit on
process wastewater discharges (e.g., zero discharge) and might also require specific best
management practices, or BMPs (e.g., development of a nutrient management plan).

Biologic Relationships of Birth and Weaning Traits in Pigs
Posted in: Production by admin on | No Comments
The objective of the study was to establish the relationships of litter size and pig weight at birth on survival at weaning and weaning weights in nursing pigs. The study consisted of 10,898 pigs from 1,020 litters.The data suggested that uterine space might have been an important factor in litter sizes of 14 or more. There was an inverse relationship between litter size and average piglet birth weight. For each additional pig born in a litter, the average birth weight decreased by 0.083 lb. The data indicated in litters of 9 or more the stillborns tended to be the smaller ones, whereas in small litters of 7 or more pigs, stillborns tend to be the larger ones. The number of pigs weaned per litter was closely related to the number of live pigs born per litter. The relationship was not linear as litter size at birth increased, litter size at weaning also increased but at a diminishing rate. This was most likely due to the fact that cross fostering was not allowed. Average pig weaning weight was inversely related to litter size at birth and at weaning. For each extra pig weaned per litter, there was a decrease in average pig weaning weight of 0.288 lb. For every 0.1 lb extra at birth there was a 0.193 lb increase in weaning weight.The overall survival rate was 84.9%. For a 1.0 lb pig the survival rate was only 12%, but if the pig weighed 3.5 lbs the survival was 92-98%SVC Comments: 1) Pig birthweight is important for survivability (>3.5 lbs. 92-98%).
