Choline chloride deficiency in poultry can lead to problems such as stunted bone growth, fatty liver, decreased egg production, and slow growth. This article details the symptoms, differential diagnosis, remedial measures, prevention strategies, and selection recommendations for different specifications of choline chloride products to help farms scientifically supplement vitamin B4 and improve production performance and economic benefits.- Polifar

L-Tryptophan, one of the four core amino acids in feed, cannot be synthesized by animals and must be supplied via diet. As a key precursor for serotonin, melatonin and niacin, it plays vital roles in protein synthesis, neural regulation and immune enhancement. This article elaborates on its physiological functions and applications across pigs, poultry, aquatic animals, ruminants and pets. It also highlights its value in promoting low-protein diets, improving animal welfare and advancing eco-friendly farming, offering insights into its future development in precision nutrition and functional feed additives. - Polifar

Betaine, as a feed additive, mainly comes in five types: anhydrous betaine, monohydrate betaine, betaine hydrochloride, compound betaine, and microencapsulated/coated betaine. Its structure is stable, although different types exhibit slight differences in appearance. It is readily soluble in water, soluble in methanol/ethanol, and sparingly soluble in ether and chloroform. It is natural, non-toxic, residue-free, and non-teratogenic/carcinogenic, enabling green farming. Due to its advantages such as methyl donor, osmotic pressure regulation, growth promotion, stress resistance, carcass improvement, appetite enhancement, vitamin stabilization in feed, and auxiliary anti-coccidiosis, it is widely used in pig, poultry, aquaculture, and ruminant farming. - Polifar
