The relevance of the present research is related to the great importance of Karakul sheep breeding in Kazakhstan and the insufficient investigation of morphological features of the skin and hair cover of Karakul lambs in modern literature. The purpose of the research was to explore the specific features of hair pigmentation and histological structure of the skin of Karakul lambs of different colour groups: black, sur, grey, and brown. The work involved the standard methods of assessing the pigment content in the hair of lambs and methods of histological studies. The study utilised statistical methods including the Kolmogorov-Smirnov criterion, one-factor analysis of variance, Fisher’s F-criterion, and the Bonferroni method, with data processed through the “PASW Statistics 17” and “Statistica 6.0” software packages. The results of the research demonstrate that the pigment content in the hair of new-born Karakul lambs depends on their colouring. Differences in pigment precipitation between different colour groups of lambs were established: pigment grains in black hairs and suras were larger, in comparison with brown and grey hairs, in which pigment was represented by the smallest grains. At the age of 19 days, no significant changes in the colouring of the lambs examined were found (p > 0.05), whereas on reaching 4 months of age, depigmentation (p < 0.05) was noted in all colour groups, which was slower in black lambs.
