Comparative digestibility of energy, dry matter, and nutrients by gestating and lactating sows fed corn-soybean meal diets without or with full fat or defatted rice bran

The physiological stage of pigs may influence total tract digestibility of nutrients because the digestibility of energy and some nutrients increases as body weight increases, but the impact of physiological stage may be greater for high-fiber diets than for diets with less concentration of fiber. Full fat rice bran (FFRB) and defatted rice bran (DFRB) are produced in the rice milling process and is available for animal feeding. However, because of the high concentration of dietary fiber, FFRB and DFRB may be better suited for diets fed to sows than for diets for weanling or growing pigs, but there is a lack of data on the digestibility of energy and nutrients in FFRB and DFRB fed to sows. Therefore, the objective of this experiment was to test the null-hypothesis that the apparent total tract digestibility (ATTD) of gross energy (GE), dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), and P in a corn-soybean meal diet and in diets containing FFRB or DFRB is not different between lactating sows and gestating sows if both groups are allowed to consume their diet on an ad libitum basis.

Effects of different levels of full fat or defatted rice bran on growth performance and carcass quality of pigs

Rice bran is the main coproduct of the production of white rice for human consumption, and is used in livestock diets around the world. Rice bran can be full fat (FFRB), with 14 to 25% fat, or defatted (DFRB), containing 3 to 5% fat.

The type of fat in the diet affects the quality of fat in the pig, because pigs deposit fatty acids in approximately the same proportions as they exist in the diet. A high consumption of unsaturated fat can inhibit the pig's own synthesis of fat, which tends to be more saturated. The amount of unsaturated fatty acids in fat can be expressed using the iodine value (IV), where high IVs correspond to more unsaturated fat. Increased IV in pig fat can lead to softer bellies, which are less valuable due to reduced shelf life, increased susceptibility to oxidative damage, and reduced belly sliceability.

Effects of feeding level and physiological stage on digestibility of GE and nutrients and concentration of DE and ME in full fat and defatted rice bran fed to gestating sows and growing gilts

Gestating sows have been found to have greater digestibility of energy than growing pigs. One possible explanation is that sows' larger intestinal tracts and more efficient fermentation of fiber allow them to extract more energy from their feed.

Gestating sows are usually restricted in their feed allowance while growing pigs are fed ad libitum. This confounds comparisons between sows and growing pigs because feeding level affects the rate at which feed passes through the intestinal tract and may affect the efficiency of digestion.

Therefore, an experiment was conducted to separate the effects of physiological stage from the effects of the level of feed intake on digestibility of gross energy (GE) and neutral detergent fiber (NDF) in full fat rice bran (FFRB) and defatted rice bran (DFRB).

Effects of full fat or defatted rice bran on growth performance of weanling pigs

Rice bran is the brown outer layer of brown rice, which is removed from brown rice to produce white polished rice for human consumption. Rice bran may be full fat, containing 14 to 25% fat, or defatted, which reduces the concentration of fat to less than 5%.

Rice bran has a high concentration of non-starch polysaccharides (NSP), primarily arabinoxylan and cellulose. NSPs decrease nutrient digestibility and thus limit the inclusion of rice bran in weanling pig diets. Recent data from our laboratory indicate that adding exogenous xylanase to diets containing full fat rice bran (FFRB) or defatted rice bran (DFRB) increases the concentrations of digestible and metabolizable energy. The objective of this experiment was to determine the effects of increased inclusion levels of FFRB or DFRB to diets without or with exogenous xylanase on growth performance.
