title: Morphological state of the digestive organs red-clawed crayfish (Cherax quadricarinatus) by the use of feed additives
abstract: The morphological structure of the digestive system organs (stomach, intestines and digestive gland) of the Australian red-clawed crayfish (Cherax quadricarinatus) was studied when using alfalfa flour in feed as an alternative additive. Crayfish were kept in laboratory conditions, at a temperature of 24-26.5 °C and divided into 3 groups: control (11 individuals); crayfish that received experimental feed version No. 1 (10 individuals) and feed version No. 2 (10 individuals).
