In this study, five adult Van cats of both sexes, which were obtained from the Van Cat Research Centre, were used as materials. After the washing of the veins of the cats with saline via an external jugular vein, latex was injected via the same vessel into the vein system. Then, materials were fixed and after solidification of the latex, the veins were dissected, identified and presented in images. The majority of the venous drainage of the face is done by the facial vein, which is the direct continuation of the linguofacial vein in the intermandibular region, and its branches. In the Van cat, the facial vein gives off the inferior . . .labial vein, the deep facial vein, the angular vein of the mouth and the masseteric branch on the lateral surface of the face. The facial vein then gives off the medial inferior palpebral vein, the superior labial vein and the lateral nasal vein at the level of the levatory nasolabial muscle and the angular vein of the eye and the dorsal nasal vein at the level of medial angle of the eye. The presence of a masseteric branch which is given by the facial vein and the ramifying of the deep facial vein into the descending palatine vein, the anastomotic branch of the superficial temporal vein and the external ophthalmic vein which is given by the deep facial vein in the Van cat demonstrates that there are differences in the presence, ramification and distribution either of the facial vein or of its branches as compared to domestic cats. - Keywords: Van cat; facial vein; anatom More less

The aim of this study was to determine the effect of colostrum quality and composition on passive calf immunity in primiparous and multiparous dairy cows. Twenty-four primiparous and 24 multiparous dairy cows were used in this study. Calves born from primiparous dairy cows comprised the first group and calves born from multiparous dairy cows constituted the second group. After birth, colostrum samples were immediately taken from dairy cows. Venous blood samples were collected from the calves before the first colostrum intake and on the 2nd, 7th, 14th and 28th days after the first colostrum intake. Blood and colostrum samples were an . . .alysed for biochemical parameters, immunoglobulin and mineral levels. Fat and crude protein levels in colostrum were determined using the Gerber and Kjeldahl methods, respectively. Immunoglobulin levels in the colostrum of multiparous cows were significantly (P < 0.05) higher compared to primiparous cows while fat ratio, LDH activity, Ca, Mg, P and K levels were lower. There was a positive correlation among colostrum immunoglobulin, gamma-glutamyltransferase, crude protein and total protein. Serum immunoglobulin, total protein, globulin and gamma-glutamyltransferase activity in all calves were increased following the colostrum feeding. However, the serum immunoglobulin, total protein, globulin and gamma-glutamyltransferase levels in the second group of calves were higher than those of the first group of calves. There was a positive correlation among serum immunoglobulin, gamma-glutamyltransferase, globulin and total protein. Fe concentrations in all calves decreased over the course of 14 days and were lower in the second group of calves compared to the first group. In conclusion, the results of this study show that the colostrum quality of multiparous cows was better than that of primiparous cows. Colostrum crude protein, total protein, gamma-glutamyltransferase along with colostrum immunoglobulin might be used to determine colostrum quality. Serum immunoglobulin, total protein, globulin and gamma-glutamyltransferase activities could be used to determine the passive transfer status of calve More less
