Digestible phosphorus needs of terminal-cross growing-finishing pigs.

The Efficacy of Aspergillus niger Phytase in Rendering Phytate Phosphorus Available for Absorption in Pigs Is Influenced by Pig Physiological Status1

We performed an experiment with 112 piglets, 32 growing-finishing pigs, and 12 sows during pregnancy and lactation to test the hypotheses that apparent total tract digestibilities of P and Ca as well as the efficacy of Aspergillus niger phytase in rendering phytate P available in pigs depend on pig physiological status. All pigs were fed diets with identical feedstuff composition either without...

“Determination of Optimal True Digestible Calcium (Ca) to Phosphorus (P) Ratio in Grower-Finishing Pigs for Minimizing Phosphorus Excretion”

Alternative Feed Ingredients for Pigs

Largely due to the demand for grains for the bio-fuel industry, the cost of feed energy will increase worldwide. Therefore, alternative energy supplying pig feed ingredients should be explored, including distillers dried grains with solubles (DDGS), field peas, wheat shorts and liquid co-products from the bio-fuel and food industry. The inclusion of DDGS in diets is limited by the fiber concent...

Diet Modification to Reduce Fecal Excretion of Nitrogen and Phosphorus in Growing-Finishing Pigs

An experiment was conducted to determine whether brewers rice can replace all corn in diets for swine and reduce fecal excretion of Nitrogen (N) and Phosphorus (P) without compromising performance and carcass quality of growing-finishing pigs. Sixteen Yorkshire x Duroc x Hampshire crosses (BW = 77±2.5 kg) were randomly assigned to either corn/soybean meal (CSM; control) or brewers rice/soybean ...

Optimum ratio to lysine of threonine, tryptophan, and sulfur amino acids for finishing swine.

Forty-eight crossbred (PIC line 26 x Camborough 15) pigs were used in two finishing trials to compare the ideal ratios of threonine (Thr), tryptophan (Trp), and sulfur amino acids (SAA) to lysine (Lys) determined for young pigs to a proposed ratio of these amino acids for finishing pigs. Trial 1 involved 20 barrows and 20 gilts that were self-fed in sex groups of two. Trial 2 was a Latin square...
