Abstract

This study was conducted to determine the effect of betaine supplementation in sow diets on blood indexes of suckling Bama mini-pigs. Forty pregnant Bama mini-pigs with 3 to 7 parities were randomly divided into two groups with 20 sows per group, and fed individually. Pigs in the control group were fed a basal diet, while others in the experimental group were fed the basal diet supplemented with 3.5 kg/t betaine hydrochloride. The trial period was from day 3 after mating to postpartum day 21. At the end of experiment, ten litters of piglets were randomly selected from each group, and 1 pig in each litter was selected for blood collection, the plasma hormone contents, antioxidant indexes and free amino acid contents were determined. The results showed that compared with the control group, the contents of cholecystokinin (CCK), peptide YY (PYY), leptin (LEP), malondialdehyde (MDA), hydrogen peroxide (H₂O₂) and alanine (Ala) in plasma of suckling piglets of betaine group were significantly decreased (P<0.05), the contents of anserine (Ans), 1-methyl histidine (1-MeHis) and 3-methyl histidine (3-MeHis) in plasma were significantly increased (P<0.05), the contents of threonine (Thr) (P=0.069), glutamate (Glu) (P=0.055) and carnosine (Car) (P=0.055) in plasma were presented a decreased tendency, and the plasma leucine (Leu) content was presented an increased tendency (P=0.069). In conclusion, the betaine supplementation in sow diets can decrease the plasma ingestion related factor level of suckling piglets, reduce the body's oxidant level, and alter the plasma free amino acid contents, which is beneficial to the growth, development and health of piglets.

Key words： betaine; suckling piglets; hormones; antioxidant; free amino acids
