Bu çalışmanın amacı Ankara Tiftik ve Halep ırkı keçilere ait kan örneklerinde bazı biyokimyasal parametreler ile malondialdehit düzeylerinin belirlenmesidir. Araştırmada, Şanlıurfa ili Eyyübiye merkez ilçesinde yetiştirilen iki farklı işletmedeki 6 aylık, klinik olarak sağlıklı, 46 adet Ankara Tiftik ve 48 adet Halep ırkı keçi kullanıldı. Bu hayvanlara ait serum örneklerinde Alkalen fosfataz (ALP), Alanin transaminaz (ALT), Aspartat transaminaz (AST), kolesterol, kreatinin, glikoz, total protein, trigliserit, üre, kalsiyum (Ca), sodyum (Na), potasyum (K), fosfor (P), magnezyum (Mg) ve malondialdehit (MDA) düzeyleri ölçüldü. Kan serumu biyokimyasal değerleri bakımından Ankara keçilerinde kolesterol (P<0.05), kreatinin (P<0.001), glukoz (P<0.01), total protein (P<0.01), Ca (P<0.001), K (P<0.001) ve Mg (P<0.05) düzeylerinin Halep keçilerine göre istatistiksel açıdan önemli derecede yüksek olduğu saptandı. Sonuç olarak, ölçülen biyokimyasal parametreler bakımından ırk farklılıklarının dikkate alınması gerektiği kanısına varıldı.

ABSTRACT:A 17-year-old purebred Arabian mare was presented with a history of uterine prolapse of 3-hour duration. The case occurred just a�er expulsion of foetal membranes in a mare aborting during the 7 th month of pregnancy. During treatment the uterus was replaced to its normal position following epidural anaesthesia. No vulval sutures were inserted. There was no vaginal discharge during the postoperative period. Rectal examination conducted 5 days later revealed that rapid involution of the uterus occurred.

This study was aimed at investigating the effects of xylazine-ketamine, xylazine-propofol and xylazine-ketamine-propofol combinations on oxidative stress, antioxidant capacity and blood gases in sheep. Excluding the control animals, the sheep included in Groups 1, 2 and 3 were administered with combinations of xylazine-ketamine, xylazine-propofol and xylazine-ketamine-propofol, respectively, by intravenous route. The comparison of the three treatment groups with the control group showed that no significant difference existed for TAS, TOS, MDA and CAT levels. The evaluation of blood gas and electrolyte levels demonstrated a significant decrease in PvO2, cSO2, Na, and Ca levels, and a significant increase in glucose levels. In result, this study showed that the three anaesthetic combinations tested did not have any adverse effect on the oxidant/antioxidant status, but caused significant alterations in blood gas levels.

Background: In this study, the serum of sheep raised on pasture in the province and districts of Diyarbakır was tested for concentrations of the essential trace elements Cr, Cu, Se, Zn, Co, Mn, ultra-trace elements like Ni, V and Ag and non-essential toxic trace elements like Al, Pb, As, Cd and Ti. Methods: The animals used in the study consisted of 313 healthy sheep at the end of lactation obtained from different districts of Diyarbakır. The closed system method of wet decomposition was used to transfer serum trace elements to the soluble phase in blood samples. Serum trace elements were analyzed using an ICP-MS device. Result: This study contributed to obtaining normal levels of Al, Ag, Ni, Ti and V trace elements in ewes at the end of lactation. It was observed that there was no difference between all districts in terms of serum Al, Ni, Cu and Zn trace element levels. In the study, differences were found in the serum Cr, Se, As and Cd trace element levels of sheep between the districts; however, it was determined that no significant deficiency or excess occurred and these levels were within normal limits. The Co and Mn levels we obtained in Diyarbakýr are much lower than the average levels reported by the researchers. We can say that the addition of Co and Mn trace elements in appropriate proportions to the rations of animals can positively affect animal health and productivity.

Background: The development of connective tissue in the fetus during the ruminant gestation period increases the need for vitamin C, which is then further increased by the course of pregnancy and lactation. As pregnancy and lactation develop, free radicals and MDA produced as a result of oxidative stress interact with functional groups in the cell, resulting in cell damage. The oxidant/antioxidant balance at this time can be calculated using the total antioxidant status, total oxidant status and oxidative status index values. This study aimed to investigate the effect of two different doses of vitamin C on oxidative stress indicators in late gestation, early and late lactation ewes and their offspring. Methods: In the study, 48 ewes of the German Meat Merino and Akkaraman breeds that were developed by crossbreeding were employed. After breeding, four groups were formed from pregnant and non-pregnant ewes. Negative Pregnancy Control group was formed from non-pregnant ewes. Positive Pregnancy Control, Positive Pregnancy Practice 1 and Positive Pregnancy Practice 2 groups were formed from pregnant ewes. After the 90th day of pregnancy, ewes in the Negative Pregnancy Control and Positive Pregnancy Control groups received saline (0.9% NaCl, 2.5 ml) injections every week concurrently with the other pregnant groups until delivery. From the 90th day of pregnancy until birth, sheep participating in Positive Pregnancy Practices 1 and 2 received weekly injections of vitamin C (625 mg/CA, 2.5 ml and 1250 mg/CA, 5 ml, respectively). Result: In the study, no statistically significant difference was found in serum MDA, TAS, TOS and OSI levels between late pregnancy, lactation and born lambs. While none of the pregnant ewes in this study aborted, vitamin C injection significantly decreased postnatal lamb mortality. This showed that vitamin C helped pregnant ewes feel less stressed throughout pregnancy and helped lower postnatal lamb mortality. In pregnant ewes, AO-effective vitamin C supplementation has been shown to have possible beneficial effects on both maternal and offspring health, whereby the number of stillbirths was reduced by vitamin C supplementation, especially in Positive Pregnancy Practice 2 lambs.
