New Tools for Precision Feeding

18The Pig Site – The current high feed costs increase the need for developing cost-effective feeding strategies for growing-finishing pigs. Well-tested mathematical models that represent nutrient utilisation for growth allow for a systematic approach to optimising feeding programmes for individual pig units, considering local pig performance potentials and available feed ingredients, as well as environmental and economic conditions.

In this paper, Professor Kees de Lange presented examples are given where the NRC (2012) Nutrient Requirements of Swine model for growing-finishing pigs is used to explore effects of gender, pig performance potentials, feed intake, and use of high-fibre co-products as feed ingredients on nutrient requirements.

These examples stress the need to monitor closely current performance and to evaluate feeding programmes regularly…>>Continue Reading<<

  1. It is best to use a conservative estimate to guard against sickness, poor quality feed, injuries, or other unplanned problems. Remember, it is easier to slow a pig’s rate of gain than to increase it. A good rule of thumb is 1.7 pounds of gain per day for modern market hogs, with a range from 1.4 to 3.0 pounds per day.

  2. The primary effects of diseaase orginasims on the reproductive process are conception failure, abortion, stillbirth in the female, and sterility (absence of sperm) in the male. Most disease orginisms do not have a direct influence on the hormonal status of the host animal. The greatest area of invasion and infection is in the reproduction tract, where diseases cause abortion in pregnant females by disrupting the placenta (see glossery) or by killing the embryo or fetus. The major diseases of concern to swine producers are Leptospirosis, Pseudorabies, and SMEDI (stillborn pigs, mummified pigs, embryonic death, and infertility). (see glossery.) Routine vaccination programs, where permissible, and veterinarian diagnosis should be used in all cases where specific disease orginisms are present.

  3. Combines scientific background information with practical advice. The nutrition of the young pig is one of the most active practical scientific fields of porcine nutrition throughout the world. The profitability of any pig farm production programme is demonstrated by the fact that maximal early growth in pigs, which depends on correct nutrition, is extremely efficient, yet rarely achieved in most commercial farm situations.This new textbook for nutrition consultants & farmers explains how to provide accurate nutrition to young swine under commercial conditions, in order to achieve maximum growth performance at minimal cost. It includes coverage of nutritional physiology, nutrient requirements, ingredients and diets, feed programs and management systems.
