Clinical and pathological findings were described in stillborn kids affected with congenital goiter in a goat flock of Beetle breed in Garmsar Iran.The observations involved seven stillborn kids with goiter, including one case with triplet fetuses and two cases with twine fetuses. The thyroid glands were clearly visible, enlarged, and palpable in all the dead kids. The fetuses had a large swelling in the cranio-ventral neck region. Upon cutting skin in each fetus, the swelling revealed the extremely enlarged thyroid gland with two almost symmetrical lobes with both lobes approximately 15 × 8 × 5 cm in size.Histopathological hyperplastic goiter was observed in four kids and colloid goiter was diagnosed in three.Twins or triplets were observed to be predisposed to congenital goitre. All the stillborn kids were twins or triplets. On the other hand, single-born kids survived and showed a normal growth rate.

The defects of the central nervous system caused by viruses are associated with tissue changes in certain areas of this system.

We conducted the current work to determine and categorize the pathologic pattern of central nervous system lesions in stillbirths and newborns small ruminants with neurological symptoms in Semnan province.

Primarily, we selected the affected animals and carried out systematic post mortem examination of lambs and kids. Subsequently, brain and spinal cords were completely removed. Processing, sectioning, and staining from different regions of the central nervous system was performed and 15 different regions of the brain and 10 different levels of the spinal cord were prepared. Subsequently, the histopathological study was performed and the observed lesions were arranged.

This study was performed on 20 lambs and kids with nonsuppurative inflammatory lesions in the brain and spinal cord. In the gross examination of the brain and spinal cord, we observed 4 cases of arthrogryposis, 1 case of spinal cord hypoplasia, 2 cases of hydranencephaly, 2 cases of porencephaly, and 1 case of cerebellar hypoplasia. According to the presence of nonsuppurative inflammation in the brain and spinal cord, 20 positive cases were categorized into 4 groups. In the first 3 groups, the main lesion was nonsuppurative encephalomyelitis and the main lesion of the fourth group was nonsuppurative encephalitis. Accordingly, 6 cases in the first group had extensive and inclusive nonsuppurative inflammation in over 75%  of the brain and spinal cord sections; in the second group, five cases had multiple scattered nonsuppurative inflammation in 50% - 75% of the brain and spinal cord sections; in the third group, five cases had non-inclusive and focal nonsuppurative inflammation in less than 50% of the brain and spinal cord sections, and in the fourth group, 4 cases had nonsuppurative inflammation in the brain without lesion in the spinal cord.

It seemed as though in each of the four pathological patterns, certain viral agents were responsible for the pathological changes.

Transfer of immunoglobulin from mother to baby through placenta or colostrum is called passive transfer (PT). The ruminant placenta is a syndesmochorial type and is a barrier against the transfer of maternal immunoglobulins from the blood to the infant. Therefore, in ruminants, the inability to transmit colostrum immunoglobulins is called Failure of Passive Transfer (FPT). This study aimed to determine the percentage of FPT in lambs and kids in Garmsar County and the effect of factors such as race, gender, mother's age, mother's parturition and type of livestock (lamb or kid) on FPT. This study was performed on 101 healthy 2-4 day-old lamb and kid in 10 herds of sheep and goats in Garmsar County. After examination, confirmation of clinical health, sex, age, race, birthday time, number of mothers, parturition, maternal age and newborn weight, 3 ml of sterile blood was obtained from the jugular vein. These samples were immediately referred to the lab in without anticoagulant tube and adjacent to the ice. The biuret method and Zn-sulfate turbidity test were determined on the level of total protein and immunoglobulin G serum. The results of this study revealed 50/50% occurrence of FPT in the lambs and kids understudy, the relationship between race and sex with the incidence of FPT, and the lack of relation between maternal age, mother's parturition and type of livestock with the incidence of FPT.

Coccidiosis is one of the most important causess of enteritis in lambs and kids and can be responsible for diarrhea, weight loss and even death. In this study a total number of 7 kids native from a flock with range ages between 3 to 4 weeks old with history of depression, loss of appetite, dehydration, emaciation and bloody diarrhea were referred for diagnosis of the disease to clinic of Faculty of Veterinary Medicine, Islamic Azad University of Shahrekord. Haematological changes included decrease in RBCs (3.5 ×106 /mm3), Hb content (5.5 ± 0.3 g/dl) also reduction PCV% (21 ± 1.85 %) and leukocytosis (21.35±0.95 × 103 /mm3) with neutrophilia (69±4 %), lymphocytopenia (24±3 % ). At necropsy, gross lesion were observed mostly in the ileum, cecum and proximal colon. This lesions containing cerebriform pattern on the serosal surface of the intestine, severe and diffuse a lot of small whitish non- pedunculated nodules on the mucosal surface of jejunum and middle ileum with hemorrhage and severe hemorrhage on the mucosa of the cecum and proximal colon. Microscopical study of ileum nodules revealed increased length of crypts, papillary hyperplasias of the mucosal epithelium, mild inflammatory reaction and presence of developmental stages of the Eimeria in the hyperplastic enterocytes. Microscopic examination of the intestine is required in order to determine how much damage has occurred, particularly in the areas between the white nodules. In conclusion Coccidiosis control Programme major importance in domestic animals.
