The purpose of this study was to evaluate the relationships of litter weaning weight (LWW), number weaned (NW), mean pig weaning weight (PWT), litter birth weight (LBW), and survival percentage (%S) with number after transfer (NAT) and number born al

The purpose of this study was to evaluate the extent how performance traits in purebred pigs, including days to 113.4 kg (D113), ultrasound backfat depth (BF), and loin muscle area (LMA), are affected by variation in birth weight (BTW) and weaning we

Barrows (n = 2,178) and gilts (n = 2,274) were fed either high-energy or low-energy diets from 27 kg of BW to target BW of 118, 127, 131.5, and 140.6 kg over 12 monthly replicates. Carcass primal cut and subprimal cut weights as well as optical probe

Enrichment of pullet cages with perches has not been studied. Our objective was to determine if access to metal perches during all or part of the life cycle of caged White Leghorns affected egg traits, foot health, and feather condition. Treatment 1

The objective of this trial was to evaluate sources and magnitude of variation for pork cut weights. The weights of 5 primal and subprimal cuts were evaluated from 1,688 barrows and gilts of 3 sire and 2 dam lines at target market BW of 113, 127, or

Current methods to adjust pig performance data to a constant BW or age assume linear relationships between the growth of the measurement and either age or BW. Serial BW and ultrasonic measurements from a set of gilts were used to provide an example o

Two genetic lines of barrows and gilts with different lean growth rates were used to determine BW and mineral growth from 23 to 125 kg BW. The experiment was a 2 × 2 × 5 factorial arrangement of treatments conducted in 2 replicates. Six pigs from e

The amino acid contents of whole body were determined in male ducks at 5 age intervals from d 1 to 29 post hatch. Whole body homogenates were analyzed of dry matter, nitrogen, and amino acids and used to determine amino acid accretion rates and effic

A stochastic model was developed to evaluate the effects of total number of pigs born and dam parity on pig compositional growth and postweaning profitability. The survival of pigs was modeled as a function of parity and of birth weight. Two manageme
