    ABSTRACT: In modern pig farming more and more attention is paid to body condition score. On most commercial farms feeding of gilts and sows is based on body condition. The goal is that sow does not gain or lose too much of a body weight between farrowing and insemination. Maintenance of body weight (condition) of sows within the optimum value (3 in the time of farrowing and 2,5 during matting) over their lifetime can result in optimal reproductive results. In contrast, inadequate control of condition of the sow may lead to difficulty in farrowing and occurrence of health problems. The aim of our study was to estimate body condition at 90th day of gestation on a farm of commercial type.

    ABSTRACT: In this paper the results of metabolic blood parameters examination of lactating cows are presented. We measured levels of glucose, total proteins, albumin, urea, and total bilirubin in blood, and the activity of aspartate aminotransferase (AST) and alanine transaminase (ALT). The aim of this work is to show difference in metabolic status of three different categories of dairy cows in intensive rearing conditions.

    ABSTRACT: this paper we presented metabolic profile of sows from one industrial type farm. We monitored the following parameters: phosphorus, calcium, bilirubin, total protein, glucose, magnesium, and urea in blood. We found 7 sows with phosphorus level in normal range, 4 sows with hypophosphatemia and 9 with hyperphosphatemia. In 5 sows calcium values ranged within the physiological values, in 13 sows is moved above the normal values and in 2 ranged below the permissible value. Bilirubin was in all 20 sows above the permitted value. Total proteins were in 6 sows in normal range, in 13 were bellow and in 1 above upper physiological limit. State of hypoglycemia was founded in 15 sows and in 5 sows glucose levels were in physiological limits. Magnesium values were above the physiological values in 9 sows, in 6 bellow limits and in 5 was within tolerable limits. Values of urea are normal in 18 sows and above physiological limit in 2 sows.

    ABSTRACT: This paper gives a detailed analysis of the applied biosecurity measures in the production of boar sperm at a swine reproduction center. Biosecurity indicators (existence of a written biosecurity plan, isolation, introduction of newly acquired animals into the herd, herd health, assessment of the personnel attitude towards equipment, traffic control, attitude towards visitors, feeding and watering control, manure management, disposal of dead animal carcasses, attitude towards other animals, rodents and birds control, sanitation) were viewed and evaluated by rating scale: (5) -excellent, (4) -very good, (3) -good, (2) -sufficient, (1) -insufficient, there are resources for improvement (0) -insufficient, with no resources for improvement. Obtained data were analyzed in the SWOT process, taking into account all the strengths, weaknesses, threats and opportunities for improving the biosecurity level. The situation in the center is rated as very good, with an average rating of 4.15. However, one disadvantage is serious and related to the boar facilities isolation possibilities, taking into account their location and the presence of two types of male breeding animals (boars and bulls) in the same location. Newly acquired breeding animals are purchased from various sources, but with a rigorous regime of control and not at the same time.

    ABSTRACT: Dairy cow herd sterility is nowadays considered pathological syndrome, and is part of everyday dairy cattle pathology, it is not a disease sui generis. Etiology of herd infertility is complex and includes several groups of factors. Factors that cause herd sterility are alimentary, hereditary, hormonal, infectious, environmental and insemination errors. In the etiology of herd infertility scarce and unbalanced diet dominates in 40 to 75 percent. Due to the complex etiology in treatment of herd infertility no general and unique prescription exists. Increased milk production and selection of cows for the production level of over eight thousand litters of milk in lactation, introduction of MIX and MONO meals and mostly stable keeping cows, and the demand disturbs metabolism and always reduces the fertility of dairy cows. Because of reduced fertility, getting a small number of calves, reduced milk production and the inability to achieve optimal fertility than eighty per cent, the question of economic feasibility of growing dairy cattle. Since in clinical practice appears a number of forms and symptoms flock sterility, the author considers the most common forms herd sterility in three dairy cattle farms and veterinary procedures in solving herd sterility of dairy cattle, with the aim of herd fertility is eighty-five percent, because the reproduction key to the success of each of cattle production. Different etiologic factors, genetic and paragenetic lead to decreased fertility. We have in a two-year period, on three dairy farms, investigated the most common forms of infertility. Way of keeping as well as nutrition and milk production was also different. In the tests we have discussed the impact of heat stress on the amount of milk production and fertility of cows. We have taken parity of calving cows, bull semen fertility, and the birth of twins and size of herds of dairy cows into account.

    ABSTRACT: In this lecture we represented results of our project research. Our research was done on swine farms. Disease like neonatal scour, edema disease, esophagogastric ulcer, osteodistrophia, actinobaciulosis, atrophic rhinitis, dysentery and recent times, proliferative enteropaties, could be controlled by use of both prphilactic and therapeutic measures and increase control of component services. Especially critical periods are sowing, 24-38 hours after sowing, 7-10 days after sowing and period 10-14 dasys after repulsion. In modern pig production, genetics aims to improve the productive capacity of the existing breeds of pigs, which are used in industrial-type pig farms, as well as creating new forms of quality breeds with greater genetic potential from growing in the pure breed or cross for commercial aims. Aims of this paper was to through the issue whether cytogenetic methods could be used as part of plans to biosicurity industrial-type pig farms to try to reach the cytigenetic methods everyday practice. Cytogentic methods allow detection of genetic abnormalities. Revelling animals that carry chromosomal changes should lead to their elimination from reproduction. We presented cytogenetic analysis of breeding sows on industrial pig farm. In most sows we found phenomenon of transformed karyotype which appears in characterised aneuploid, poliploid cells and cell structural chromosomal aberrations.
