“…Betaine (glycine betaine, trimethylglycine) is a naturally occurring, nontoxic amino acid derivative that is commonly found in a large number of plant and animal species (Saarinen et al, 2001). Betaine plays an important function in amino acid and lipid metabolism and antibody production in practical animal production (Verreschi et al, 2000;Kim et al, 2003;Zulkifli et al, 2004). Much of the research with betaine in animals has evaluated effects on growth and carcass traits, and usually different levels of betaine have been fed.…”

This study was carried out to compare the growth performance and quality properties of pork from finishing pigs fed different levels of betaine. A total 120 female pigs (Landrace×Yorkshire×Duroc) were fed either a control commercial diet or the control diet supplemented with 2, 4 and 6% betaine for 31 days. The average daily feed intake (ADFI) of the 2% diet was lower than of the other treatment groups. The average daily gain (ADG) for pigs fed betaine diets was significantly higher (p<0.05) compared with nonsupplemented diets. Feed conversion ratio (FCR) of pigs fed betaine diets was significantly lower (p<0.05) compared with nonsupplemented diets. pH of loin and ham samples were not significantly different between dietary groups, whereas CIE a* (redness) of pork loin was increased by dietary betaine. Also, the shear force value of loin was significantly higher (p<0.05) in pigs given dietary betaine compared with non-supplemented diets, but no significant differences were found in cooking loss by the loin among diets with different levels of betaine (p>0.05). Dietary supplementation with betaine decreased total cholesterol concentrations in blood, and increased saturated fatty acid and decreased unsaturated fatty acid levels in muscle. Pigs supplemented with betaine had increased betaine concentrations in the loin muscle. It was concluded that dietary betaine supplementation of finishing pigs can improve growth performance and reduce blood cholesterol concentrations. It was also concluded that dietary betaine produced detectable betaine concentrations in the lion muscle.

Ninety six growing pigs (Duroc×Landrace×Jia) were used to investigate the effects of betaine on growth, nutrient utilization, carcass composition and meat quality at different levels of betaine in the diet. The pigs were randomly assigned by weight to four groups, each of which was replicated three times with eight pigs per replicate. Four groups were fed with diets supplemented with 0, 1,000, 1,500 and 2,000 mg/kg betaine. The pigs were grown from 20 kg live weight to approximately 64 kg. The 1,000 mg/kg and 1,500 mg/kg betaine treated groups increased average daily gain by 13.20% (p<0.01) and 9.28% (p<0.05) and average daily feed intake by 7.30% (p<0.05) and 7.33% (p<0.01) respectively and decreased feed conversion ratio by 7.93% (p<0.01) and 6.55% (p<0.05) respectively compared to the control group. However, these differences were not found in the other betaine treated groups. The 1,000 mg/kg betaine treated group significantly elevated carcass lean proportion by 7.49% (p<0.05) and longissimus muscle area by 19.12% (p<0.05) and contents of ether extract and myoglobin in longissimus dorsi. by 34.21% (p<0.01) and 29.56% (p<0.01) respectively, reduced carcass fat proportion and fat depth by 27.21% (p<0.05) and 14.86% (p<0.05) respectively compared to the control group. It is concluded that betaine supplementation in the diets may improve growth performance and carcass characteristics in growing pigs.
