1, Njirimara anụ ahụ na kemịkalụ na ntọala ọrụ nke potassium diformate

Potassium diformatebụ ngwakọta kristal nke e ji njikọta nke formic acid na potassium diformate mepụta n'ime oke molar 1:1, yana usoro molekul CHKO ₂. Ọ na-apụta dị ka ntụ kristal ọcha ma na-agbaze ngwa ngwa na mmiri. Nnu acid organic a na-anọgide na-adịgide adịgide na gburugburu acidic, mana ọ nwere ike kewaa ma wepụta formic acid na potassium diformate na gburugburu na-anọpụ iche ma ọ bụ na-adịghị ike alkaline (dịka eriri afọ ọkụkọ). Uru pụrụ iche ya dị n'eziokwu ahụ bụ na formic acid bụ obere abụba acid nwere ọrụ nje bacteria kachasị ike n'etiti acid organic a maara, ebe potassium ion nwere ike ịgbakwunye electrolytes, ha abụọ na-arụkọ ọrụ ọnụ.

Mmetụta nke nje bacteria napotassium diformatea na-enweta ya n'ụzọ atọ:

Nnyocha egosila na itinye 0.6% potassium diformate nwere ike ibelata ọnụọgụgụ Escherichia coli n'ime cecum nke ọkụkọ broiler site na ihe karịrị 30%;
Site n'igbochi mmụba nke nje bacteria na-emerụ ahụ, na-akwalite mbubata nje bacteria bara uru dị ka nje bacteria lactic acid n'ụzọ na-apụtaghị ìhè, na ime ka nguzozi nke microbiota eriri afọ dịkwuo mma.

2. Mee ka ọrụ nri dịkwuo mma ma melite arụmọrụ ojiji nri

Belata uru pH nke eriri afọ, mee ka pepsinogen rụọ ọrụ, ma kwalite mmebi protein;
