Feed Energy Evaluation for Growing Pigs*
Pigs require energy for maintenance and productive purposes, and an accurate amount of available energy in feeds should be provided according to their energy requirement. Available energy in feeds for pigs has been characterized as DE, ME, or NE by considering sequential energy losses during digestion and metabolism from GE in feeds. Among these energy values, the NE system has been recognized ...
متن کاملLocally Produced Agricultural By-Products as Feed Sources for Pigs
Raw fiber concentrates, products with high content in cellulose, hemicellulose and lignin, are new sources of concentrates with high biological and functional value. Recent studies have demonstrated that raw fiber concentrated products have a positive influence on intestinal development, in health status of piglets and in sows. Agricultural by-products with high lignocellulose content are commo...
متن کاملOptimum duration of performance tests for evaluating growing pigs for growth and feed efficiency traits.
The optimum duration of test for the measurement of ADG, ADFI, feed:gain ratio [which is the reciprocal of the efficiency of gain (G:F) and therefore increases as the efficiency of gain decrease and vice versa], and residual feed intake was examined in growing pigs. Data from 144 hybrid (mainly Large White x Landrace) pigs involved in a longitudinal (n = 54) and serial slaughter (n = 90) experi...
متن کاملAlternative 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...
متن کاملAmino acid digestibility of plant protein feed ingredients for growing pigs.
Two experiments were designed to determine the N and AA digestibility of various protein sources (potato protein concentrate, soy protein concentrate, soy protein isolate, linseed meal, sunflower meal, cottonseed meal, canola meal, and camelina meal) fed to growing pigs. In each experiment, barrows were surgically fitted with a simple T-cannula at the distal ileum and fed 4 experimental diets a...
