| dc.description.abstract | Livestock play a vital role in the agricultural and rural economics of the developing world. Thyroid and adrenal gland play important role in galactopoisis as well as in metabolism. The present experiment was conducted on 12 Kosali cows divided into two groups - lactating and nonlactating stages with 6 cows in each group. Thyroid and adrenal gland were collected from Kosli cow of Rajnandgaon, and Durg districts of Chhattisgarh. Gross morphological and biometrical parameters of right and left thyroid gland, isthmus, right and left adrenal glands were recorded. Tissue samples were processed and histoarchitectural observations and histomorphological micrometry were made. No difference in morphology and topography of thyroid and adrenal glands were recorded in lactating and nonlactating stage. Recorded gross biometrical parameter of thyroid and adrenal glands were comparatively higher in lactating stage than nonlactating stage and was mostly nonsignificant. Whereas, in right thyroid gland craniomiddle thickness, craniodorsal thickness, mid ventral thickness mid central thickness and in left thyroid glands middle width, caudal width craniomiddle thickness mid central thickness was significant. Biometrical parameters revealed that right thyroid gland was larger than left thyroid gland. Histoarchitectural organization of thyroid and adrenal glands were same in lactating and nonlactating stage. In thyroid glands in lactating stage the percent of small follicles were more (75 %), whereas in nonlactating stage percent of medium follicles were more (50 %). Ratio of large follicle and small follicles were in between lactating and nonlactating stage were 1.0 : 4.0 and. 2.50 : 1.0 respectively. Diameter of large, medium and small follicles were more in nonlactating stage in right and left lobes of thyroid gland and was nonsignificant. Thyrocyte height was more and nonsignificant in lactating stage. No apparent difference was seen in the distribution of parafollicular cells in lactating and nonlactating stage. Isthmus of lactating glands showed more parenchyma whereas in nonlactating glands it was more fibrous. Adrenal capsule, zona glomerulus, zona fasciculate, zona reicularis and medulla were comparatively thicker in lactating stage and was nonsignificant. The recorded histoarchitectural observations of adrenal glands were slightly higher in left adrenal gland than right adrenal gland in lactating stage. Whereas, in nonlactating left adrenal gland no definite pattern were seen. | |
