Recommendations for amino acids, calcium and phosphorus are presented for barrows and gilts at different levels of lean gain Tables 5A-C. Brumm, E. McGlone, M. Environmental factors, such as floor space allowance, temperature, and disease or health status have a great impact on feed intake.

An experiment was conducted to evaluate the response of gilts and barrows to two levels of lysine. Upper values do not represent safe or tolerance levels, but instead a reference point above which further additions will not likely improve performance. In: P.

If pigs are kept in an environment that is too hot, feed intake will be reduced by approximately 0. Obtaining performance data for a production system can be accomplished in one of two ways:. Spoolder, P. Although disease status is difficult to measure objectively, a general impression of the health of pigs can usually be obtained by disease profiling the herd using serology.

Gonyou, H. The amount of feed a pig wastes can be significant and highly variable depending on feeder type and management.

While the percentage of small and medium sites using split-sex feeding has remained fairly constant since This allows for the possibility of using fewer feeding phases during the grow-finish period which may represent practical and cost-effective advantages in feed manufacture, storage and delivery.

Feeding a lower cost diet — due to lower protein and amino acid levels — to a higher intake animal is economically attractive, especially going into the fall and winter markets. Lysine levels Table 1 were closely set to the estimated requirements for maximum growth rate Experiment 1 or were slightly below the estimated requirements for maximum growth rate to simulate a field approach on lysine levels Experiment 2.

The challenge to the producer is to manage all variables in such a way that productivity and profitability are optimized. A lb pig has a floor space requirement of approximately 8. In this case, increasing the energy density of the diet by adding fat will be advantageous.

Regardless of dietary energy concentration, the recommended daily intake of nutrients is constant. Specific recommendations for trace mineral and vitamin additions to growing-finishing swine feed are shown in Table 7.

How many diet phases should I feed throughout the finisher period?
