Effect of diet and exercise on performance, carcass traits and plasma components of growing-finishing barrows.
Twenty-four barrows (approximately 25 kg initial wt) were used in each of three 2 X 2 factorially arranged trials to study effects of exercise (not exercised vs walking 30 min/d, 6 d/wk on a treadmill) and diet (low energy vs high energy) on performance during the growing-finishing period. Average daily gain (ADG) of barrows not exercised was greater (P less than .07) than that of those exercis...
متن کاملFeeding behavior of growing-finishing pigs reared under precision feeding strategies.
The feeding behavior of growing-finishing pigs reared under precision feeding strategies was studied in 35 barrows and 35 females (average initial BW of 30.4 ± 2.2 kg) over 84 d. Five different feeding programs were evaluated, namely a conventional 3-phase program in which pigs were fed with a constant blend of diet A (high nutrient density) and diet B (low nutrient density) and 4 daily phase-f...
متن کاملEffects of supplemental selenium on swine. II. Growing-finishing.
The effects of dietary selenium (Se), copper (Cu) and zinc (Zn) on growth characteristics, selected blood parameters and carcass traits in growing-finishing swine were evaluated in two experiments. In the first experiment, 48 Duroc barrows and gilts weighing approximately 30 kg were al lot ted by sex and weight to six dietary treatments. They were fed a basal 16% crude protein diet containing ....
متن کاملChanges in the histochemical properties and meat quality traits of porcine muscles during the growing-finishing period as affected by feed restriction, slaughter age, or slaughter weight.
In this study, the degree of contractile and metabolic development of myofibers in porcine LM, rectus femoris (RF), and dark and light portions of the semitendinosus (STD and STL, respectively) was determined, and their impact on meat quality was compared at the same age but different BW (trial 1) or at a given BW but different age (trial 2) in 48 Swiss Large White barrows from 12 litters after...
متن کاملEffect of various dietary arginine: lysine ratios on performance, carcass composition and plasma amino acid concentrations of growing-finishing swine.
Crossbred growing-finishing pigs (112 barrows, 48 gilts) were used to determine the effect of reducing excess dietary arginine, through feedstuff variation, on performance, carcass composition and plasma amino acid concentrations. Diets contained five, four, three or two times the NRC requirement for arginine. Lysine in all diets was formulated to be equal to NRC requirements, and all diets con...
