Blood parameters in dermatitis of various etiologies in cattle

The purpose of the research is to identify a general pattern in the change in hematological and biochemical parameters in any lesions of cattle skin.Materials and methods. The work was carried out in October-November 2021 in the conditions of farms in the Ipatovsky district of the Stavropol Territory on cattle aged 9–12 months and 90–120 kg of body weight. During the veterinary clinical examination, four groups of fve heads each were formed, one of the groups was a control. Animals of the control group had no clinical signs of dermatitis. The experimental groups of animals were divided depending on the degree of intensity of skin lesions into mild, moderate and generalized forms of manifestation of dermatitis. The results obtained were processed statistically.Results and discussion. A veterinary clinical examination of this livestock made it possible to establish the dependence in case of damage to the skin not only in changes in temperature, respiratory rate and pulse, but also in blood parameters. The body temperature of calves with a generalized form of dermatitis increased by an average of 0.5 degrees, breathing increased by six units per minute, the pulse rate increased by 15–18 beats per minute. In calves with mild and moderate manifestation of dermatitis, these parameters did not have signifcant changes and were within the normal range. From hematological indicators, hemoglobin had a general tendency to decrease with increasing intensity of the lesion or aggravation of the pathological process. Such indicators as ESR, leukocytes, neutrophils, eosinophils, on the contrary, tended to increase, especially in the generalized form. The slowdown of erythropoiesis and thrombocytopenia in the generalized form of dermatitis is presumably associated with intoxication of the body of calves. An increase in ESR, the number of eosinophils indicates an inflammatory process occurring in the animal's body. From biochemical indicators, an increase in the level of bilirubin, AST and ALT, creatinine, alkaline phosphatase indicates toxic liver damage due to intoxication of the body of calves due to inflammatory factors and decay products of affected skin cells

Seasonality of Oestrus ovis infection in sheep in the steppe zone of the Stavropol Territory

The purpose of the research is to study the seasonality of Oestrus ovis infection in sheep depending on the management conditions in the steppe zone of the Stavropol Territory.Materials and methods. The research to study the botfly flight seasonality was conducted on two farms in the Apanasenkovsky District and two farms in the Ipatovsky District of the Stavropol Territory. The number of sheep botflies was studied in the entire flight season by regular inspection and counting of the parasite adult stage on the outer surfaces of sheephouse walls and the side walls of sheds with a 15 day-interval.Results and discussion. The sheep botfly flight season was 5.5 months (from May 25–30 to October 31–November 11). Two increases in the number of botflies were observed during this period: in July and September–October. Infection of sheep with oestrosis in 1971 had two peaks (the first, May to June; the second, August to November). Due to the earlier spring 2022, the first peak started in the second half of March and lasted until the first half of July, and the second peak was observed from the second half of August to the end of November

Environmental monitoring of natural waters in Krasnodar and Stavropol Territories

The environmental monitoring of natural waters in Krasnodar (Uspensky and Novokubansky districts) and Stavropol (Kochubeyevsky District) Territories was conducted. In the course of study, various elements and compounds harmful to animals and humans, which exceed maximum permissible concentrations, were identified

Persistent activity and therapeutic efficacy of Delcid® 7.5 against scab mites (<i>Psoroptes ovis</i>) in sheep

The purpose of the research is to study persistent activity and therapeutic efficacy of Delcid® 7.5 against scab mites Psoroptes ovis in sheep.Materials and methods. The studies were performed in the Bukhty peasant farm enterprise in November 2021 on the Kizlyarsky District winter pastures in the Republic of Dagestan. Three groups of sheep were formed, of which two groups (second and third) had a confirmed clinical diagnosis of psoroptic mange (P. ovis) and one group (first) was free from scab mites. Sheep from the first and second groups were treated with Delcid at a dose of 10 ml of the drug per animal. After 10 days, sheep from the second group were treated with the drug repeatedly at the same dose. Sheep from the first and second groups were treated with the drug applied on dry and intact skin of the back along the spine using the drop method. The third control (infected) group of animals was not treated. All experimental groups of sheep were kept in a common flock. The Delcid persistent activity and thera-peutic efficacy were evaluated by clinical examination and microscopy of the skin for P. ovis mites before the experiment started and at 1, 3, 7, 10, 14, 21, 25 and 30 days after treatment in the first group and at 1, 3, 7, 11, 13, 17, 20, 24, 31, 35 and 40 days in the second and third groups of sheep.Results and discussion. It was found that Delcid 7.5 showed persistent activity in sheep against psoroptic mange pathogens for 21 days after a single treatment at a dose of 10 ml per animal. Delcid acaricidal effect after double treatment against P. ovis was 31 days

Работа проведена в октября-ноябре 2021 г. в условиях хозяйств Ипатовского района Ставропольского края на крупном рогатом скоте в возрасте 9–12 мес. массой тела 90–120 кг. В ходе ветеринарно-клинического обследования были сформированы четыре группы по пять голов в каждой, одна из групп была контрольной. Животные контрольной группы не имели клинических признаков дерматитов. Опытные группы животных были разделены в зависимости степени интенсивности поражения кожи на слабую, среднюю и генерализованную формы проявления дерматитов. Полученные результаты обработаны статистически.Результаты и обсуждение. Ветеринарно-клинический осмотр данного поголовья позволил установить зависимость при поражении кожного покрова не только в изменениях показателей температуры, частоты дыхания и пульса, но и показателей крови. Температура тела у телят с генерализованной формой дерматита повышалась в среднем на 0,5 градуса, дыхание учащалось на шесть единиц в минуту, частота пульса возрастала на 15–18 ударов в минуту. У телят со слабым и средним проявлением дерматита данные показатели не имели значимых изменений и находились в пределах нормы. Из гематологических показателей, гемоглобин имел общую тенденцию к снижению с ростом интенсивности поражения или усугубления патологического процесса. Такие показатели как СОЭ, лейкоциты, нейтрофилы, эозинофилы, наоборот, имели тенденцию к увеличению, особенно при генерализованной форме. Замедление эритропоэза и тромбоцитопении при генерализованной форме дерматита предположительно связаны с интоксикацией организма телят. Повышение СОЭ, числа эозинофилов свидетельствует о воспалительном процессе, происходящем в организме животного. Из биохимических показателей, повышение уровня билирубина, АСТ и АЛТ, креатинина, щелочной фосфатазы свидетельствует о токсическом поражении печени вследствие интоксикации организма телят за счет воспалительных факторов и продуктов распада пораженных клеток кожи

Исследования проводили в ноябре 2021 г. на зимних пастбищах Кизлярского района Республики Дагестан в КФХ «Бухты». Были сформированы три группы овец, из которых две (вторая и третья) с подтвержденным клиническим диагнозом псороптоз (P. ovis) и одна (первая) – свободная от чесоточных клещей. Овцы первой и второй групп были обработаны дельцидом в дозе из расчета 10 мл препарата на одну голову. Через 10 сут овец второй группы подвергали повторной обработке препаратом в той же дозе. Обработку овец первой и второй групп проводили методом капельного нанесения средства на сухую и неповрежденную кожу спины вдоль позвоночника. Третья контрольная (зараженная) группа животных не подвергалась обработке. Все подопытные группы овец содержались в общей отаре. Оценку персистентной активности и терапевтической эффективности дельцида проводили путем клинического осмотра и микроскопии кожи на наличие клещей P. ovis до начала опыта и через 1, 3, 7, 10, 14, 21, 25 и 30 сут после обработки в первой группе и через 1, 3, 7, 11, 13, 17, 20,24, 31, 35 и 40 сут во второй и третьей группах овец.Результаты и обсуждение. Установлено, что дельцид 7,5 после однократной обработки в дозе 10 мл на одну голову проявил персистентную активность у овец против возбудителей псороптоза в течение 21 сут. Акарицидный эффект дельцида после двукратной обработки против P. ovis составил 31 сут
