The pork consumer demands a quality product with a lower fat content, requiring the nutritionist to look for new alternatives in the feeding of pigs. The objective of this study was to evaluate the effect of dietary betaine. The per- formance and dressing proportion were evaluated, a total of 30 finishing barrows (Landrace × Yorkshire) were fed a control diet or with the experimental diet added with 0.1% betaine for 29 days. The average daily feed intake (CD- PA) was similar in both groups (P>0.05). The average daily weight gain (GDP), feed conversion (CA) and dressing proportion (RC) in betaine group was significantly higher (p<0.05) compared to the non-supplemented diet. Backfat thickness (EGD) was lower in the experimental group (p<0.05). The dietary betaine inclusion of 0.1% in barrows improves daily weight gain, feed conversion and reduces carcass fat content.

Keywords : betaine; pigs; fat; dressing proportion; nutrition.
