Outline
Objective To investigate the disintegration and dissolutionproperties of alprogesterone as a feed additive under differentenvironmental conditions, and to develop a suitable tablet for pig farmfeeding. Methods The prescription was screened by 3-factor and 3-levelorthogonal test, and the disintegration time, dissolution and appearancequality of the tablets were tested. Results The disintegration time ofthe optimized allyl gestrel was $7\sim {15}\mathrm{\;{min}}$ , which was better than $2 \sim 5\mathrm{\;{min}}$ of conventionaltablets. Conclusion The optimized dissolution and content of allylgestrel meet the standard, which is convenient for sows to consume andcan meet the feeding needs of pig farms.
