The effects of increasing dietary energy density on growing-finishing pig growth performance and carcass characteristics

Eighty crossbred gilts were used in a growth trial to evaluate the effects of increasing dietary energy density on growing-finishing pig growth performance and carcass characteristics. In this trial, adding fat to corn-soybean meal diets with a constant calorie: lysine ratio to increase the energy density during the growing phase (98 to 160 lb) improved feed efficiency with no influence on growth rate. However, increasing the energy content of the diet by adding fat had no benefit during the finishing phase (160 to 233 lb).; Swine Day, Manhattan, KS, November 16, 199

Effects of increasing zinc oxide on starter pig growth performance

Four hundred and twenty pigs (initially 9.8 lb and 13 d of age) were used to evaluate the effects of increasing zinc oxide in starter diets. Results that suggest 3,000 ppm and 2,000 ppm zinc, from zinc oxide, improve growth performance in phase I and II diets, respectively.; Swine Day, Manhattan, KS, November 16, 199

Effects of lactose sources on nursery pig growth performance

A study was conducted to evaluate different sources of pure lactose as a substitute for spray-dried, edible-grade whey in starter diets. Results suggest that pure lactose can replace the lactose provided by dried whey in phase I starter diets. However, numerical differences in growth performance occurred among the lactose sources used.; Swine Day, Manhattan, KS, November 16, 199

The effects of dietary energy density and lysine:calorie ratio on the growth performance of the 20 to 55 lb pig

A total of 336 barrows (initially 21.8 lb and 31 ± 2 d of age) was used to evaluate the results of increasing levels of choice white grease and lysine:calorie ratio on pig performance. Increasing levels of both choice white grease and lysine:calorie ratio improved the growth rate and efficiency of pigs fed from 20 to 55 lb.; Swine Day, Manhattan, KS, November 21, 199

The effects of substituting deproteinized whey or pure lactose for dried whey on starter pig performance

A study was conducted to evaluate the effects of replacing all or half of spray-dried, edible-grade whey with deproteinized whey or pure lactose on starter pig performance. No differences in pig performance were observed. Therefore, high quality deproteinized whey and lactose are effective replacements for the lactose provided by dried whey in starter pig diets.; Swine Day, Manhattan, KS, November 16, 199

The effects of supplementing growing-finishing pig diets with carnitine and(or) chromium on growth and carcass characteristics

Eighty crossbred gilts (initially 83 lb) were used to examine the effects of 50 ppm carnitine and(or) 200 ppb chromium from chromium nicotinate on growth performance and carcass characteristics. In this trial, adding carnitine and(or) chromiunm to the diets of high-lean growth finishing gilts did not increase carcass leanness. However, the combination of carnitine and chromium improved the color characteristics of the longissimus muscle.; Swine Day, Manhattan, KS, November 21, 199

However, the combination of carnitine and chromium improved the color characteristics of the longissimus muscle.; Swine Day, Manhattan, KS, November 21, 199

The effects of substituting spray-dried whole egg from egg grading plants for spray-dried plasma protein in phase I diets

A study was conducted to evaluate the effects of replacing spray-dried plasma protein with spray-dried whole egg from egg grading plants on starter pig performance. Up to 50% (3.5% of the diet) of spray-dried plasma protein can be replaced with spraydried whole egg (6% of the diet) without influencing performance of starter pigs.; Swine Day, Manhattan, KS, November 16, 199
