The impact of functional teat number on reproductive throughput in swine.

The objective was to evaluate the impact of functional teat number on reproductive throughput in swine. Data included 735 multiparous Landrace × Large White F1 females. Sow underlined traits consisted of total teat number (), functional teat number (), nonfunctional teat number (), and number of functional mammary glands ().

Utilizing NU to Access the Activity Levels in Pigs with Varying Degrees of Genetic Potential for Growth and Feed Intake.

Feed cost accounts for over two-thirds of the variable cost of production. In order to reduce feed costs without sacrificing production numbers, feed efficiency must be improved. Calorie expenditure has been difficult to quantify in the past but is understood to impact residual feed intake (RFI) greatly.
