Inconsistencies in feeding level of dairy cattle to their feed needs leads to various metabolic diseases, including ketosis. The purpose of our work is to study changes in the metabolism of both sexually mature representatives of dairy cattle and young animals obtained from them. The article states the following causal factors of ketosis occurrence in cows: excessive amount of fat substances, imbalance of various chemical elements in feeding diet. The pathology of carbohydrate-fat metabolism during ketosis in cows was characterized by a significant change in blood biochemical parameters, namely, an increase in triglycerides (up to 0.7 ± 0.07 mmol/l), cholesterol (up to 2.7 ± 0.15 mmol/l), non-esterified fatty acids (up to 1.93 ± 0.19 mmol/l), KET (up to 2.4 ± 0.18 mmol/l), low glucose concentration (up to 1.07 ± 0.12 mmol/l) and alkaline reserve (up to 17.8 ± 1.5 mmol/l). Low level of triglycerides, cholesterol, and alkaline reserve, as well as high values of non-esterified fatty acids, KET, and glucose characterize the exchange in calves from cows with ketosis relative to calves born by cows without metabolic pathology.
As a result of laboratory investigations, the Rosselkhoznadzor Maritime Inter-Blast Veteri-nary Laboratory confirmed the presence of DNA from the African Pig Plague (ACS) virus in the wild and in private accessories in the Primorsky Territory. In all of 2019, 50 APC flares were recorded, although the province was previously consid-ered to be a APC success. Veterinary specialists of the Primorsky Krai region in April 2020 man-aged to eliminate all pockets of African plague of pigs. In April 2020, the Russian veterinary spe-cialists of the Primorskaya Krai region managed to eliminate all pockets of African pig plague. However, by mid-2020, Primorje experienced new outbreaks of APC, with 45 cases recorded by early autumn. The disease can occur at any time of the year. The source of the ACS causative agent is sick and sick pigs. Since the virus can spread not only with infected viral animals, including the incubation pe-riod, but also through various infected objects, the products of the infected pigs are particularly dangerous (meat, meat products, lard, blood, bones, hides, etc.). Virus-infected food and combat wastes used to feed pigs without careful venting have in most cases infected pigs with the African plague. Natural and legal persons who are the owners (owners) of pigs are obliged to carry out pre-ventive measures to prevent the emergence and spread of ACS.

The muscles of the abdominal wall of the Raccoon dog, as in most mammals, are represented by three broad muscles – the external and internal oblique and transverse abdominal muscles and one long muscle, the straight abdominal. The external oblique abdominal muscle is represented by a broad muscle layer located on the lateral and ventral surfaces of the abdominal wall. It originates from the edges. Below it is the internal oblique abdominal muscle, consisting of the costal, ab-dominal and inguinal parts, bundles of muscle fibers that originate from the ribs, sternospinal fascia and inguinal ligament, respectively. Under the internal oblique abdominal muscle is the transverse abdominal muscle, which starts from the ribs and transverse processes of the lumbar vertebrae. Ven-trally, all the broad abdominal muscles pass into broad aponeuroses, which, connecting with similar aponeuroses of the opposite side, form a straight line of the abdomen. Also, aponeuroses are in-volved in the formation of the vagina of the rectus abdominis muscle. The rectus abdominis muscle runs through the entire body of the raccoon dog, along the ventral surface of the chest and ab-dominal walls. It starts from the first rib and ends at the pubic bones of the pelvis. In the area of the abdominal wall, the rectus abdominis muscle passes through the vaginal cavity formed by aponeuro-ses of the large abdominal muscles. All the muscles of the abdominal wall are involved in the for-mation of the inguinal canal, through which the abdominal cavity communicates with the scrotal cavity. Innervation of all abdominal wall muscles is carried out by the ventral branches of the tho-racic and lumbar spinal nerves: intercostal, costal-abdominal, ileo-submandibular and ileo-inguinal. Due to the increase in the lumbar bone segments to seven, the Raccoon dog has two ileo-submandibular nerves – cranial and caudal.
The transverse abdominal muscle in all the animal species studied belongs to the dynamic type of muscle, and is the deepest of all the broad abdominal wall muscles. The length of the teeth of the costal part of the transverse abdominal muscle in all studied animals decreases in the caudal direction, the greatest differences in the length of the first and last teeth of the costal part are char-acteristic of the dog. In all the studied animals, the length of the transverse abdominal muscle bun-dles is directly dependent on the volume of the abdominal cavity in its various parts. The maximum value of this indicator in a dog and cat reaches in the cranial, in a rabbit in the middle parts of the abdominal cavity. The muscle plate of the transverse abdominal muscle has the maximum thickness in the costal part, in the lumbar part it gradually decreases. The percentage of the mass of the transverse abdominal muscle in a dog and a cat is ap-proximately 25 % of the total mass of all abdominal muscles. In a rabbit, this value is 30-35 %. The ventrally transverse abdominal muscle passes into a broad aponeurosis, which is involved in the for-mation of the inner wall of the vagina of the rectus abdominis muscle and the white line of the ab-domen. The maximum width of the aponeurosis is in the middle part, while the minimum width is in the caudal part.
