Abstract

To study the effects of dynamic nutrition in one day on growth performance, blood physiology and biochemistry indexes of growing pigs, 42 pigs (half castrated boars and half sows) with similar body weight of (20.52±1.78) kg were randomly assigned into 3 groups according to body weight and sex. Three corn-soybean diets with similar digestive energy and different CP levels were formulated: basal diet (CP 21.04%), high CP level diet (CP 18.11%) and low CP level diet (CP 15.29%). The pigs in the control group were fed the basal diet in all day, those in the high-low CP group were fed high CP diet for breakfast, basal diet for lunch and low CP diet for supper, while those in the low-high CP group were fed low CP diet for breakfast, basal diet for lunch and high CP diet for supper. The experiment lasted for 25 days. Blood samples of 6 pigs selected from each group were obtained on day 25, and to examine the serum biochemical indices and plasma free amino acid contents. The results showed that compared with the control group, the average daily gain in the high-low CP group was significantly increased by 9.97% (P<0.05) and that in the low-high CP group had an increasing trend (P>0.05); in the high-low CP group and low-high CP group, serum glutamyltranspeptidase activity was significantly decreased (P<0.05), serum glutamic-oxal (o) acetic transaminase (AST) activity was increased by 35.1% and 13.1% (P>0.05), respectively, and alanine transarninase (ALT)/AST was decreased by 26.12% and 24.63% (P>0.05), respectively; the plasma contents of 3 kinds of branched chain amino acids (BCAA) including Val, Ile and Leu tended to decrease in the high-low CP group (P>0.05), while those in the low-high CP group tended to increase (P>0.05); compared with the high-low CP group, all the three kinds of plasma BCAA contents were significantly increased in the low-high CP group (P<0.05); and plasma Ser content was significantly decreased in both the two experimental groups (P<0.05). These findings suggest that dynamic nutrition affects the growth performance and blood biochemistry indexes, such as the amino acid contents of pigs under the condition of the same total feed intake and nutrition in one day.
