I. The Functions of betaine and  glycocyamine 

Betaine and glycocyamine  are commonly used feed additives in modern animal husbandry, which have significant effects on improving the growth performance of pigs and enhancing meat quality. Betaine can promote fat metabolism and increase the lean meat ratio, while guanidine acetic acid can enhance the energy metabolism of muscles. A reasonable combination of the two can bring about greater effects.

2.The addition ratio of betaine and guanidine acetic acid in fattening pig feed

Based on multiple professional studies and practical experience in the industry, the recommended addition ratios of betaine and guanidine acetic acid in pig feed are as follows: * During the entire pig rearing process, it is recommended to add 600 grams of guanidine acetic acid per ton of complete feed, which can be used in combination with 200 grams of methionine or 450 grams of betaine. In the later fattening stage, the addition amount of guanidine acetic acid in one ton of complete feed can be increased to 800 grams, and at the same time, 250 grams of methionine or 600 grams of betaine can be added. For the addition of betaine, for weaned piglets, adding 600Mg/kg of betaine per ton of feed can achieve the best effect. In growing and fattening pigs, the addition of betaine can increase daily weight gain and reduce the feed-to-weight ratio. The recommended addition amount is 400-600 grams per ton of feed.

3.Precautions for the addition of betaine and guanidine acetic acid

Other nutrients in the feed can also affect the efficacy of betaine and guanidine acetic acid. For instance, the crude protein level should be no less than 16%, lysine no less than 0.90%, and the energy level no less than 3150 kilocalories per kilogram. Betaine and guanidine acetic acid can work synergistically. It is recommended to add them simultaneously for the best results. 3. For low-protein diets (with protein content below 14%), the addition of amino acids should be increased to meet the nutritional needs of pigs. At the same time, the addition of betaine and guanidine acetic acid can be appropriately raised.

4.Conclusion:

The scientific and reasonable addition of betaine and guanidine acetic acid to pig feed can effectively improve the growth performance and meat quality of pigs. However, the addition amount and proportion should be adjusted according to factors such as the growth stage of the pigs and the composition of the feed to achieve the best economic benefits. In actual operation, flexible adjustments should be made according to specific circumstances to achieve the best breeding effect.
