“…Many solutions applied to industrial farms in order to improve profitability, increase efficiency and production safety often cause discomfort, pain and stress or distress of animals while preventing their natural instinctive behavior, which is largely reflected in the economic output of production. In addition, it should be kept in mind that in most cases it is about pigs of different age categories, often of different geographical and health backgrounds, collected in a limited area, and early maturing pigs highly sensitive to stress, which inevitably leads to the creation of conditions for the emergence of infectious diseases (Uzelac and Vasiljević 2011, Vidović et al 2011, Bojkovski et al 2014. Omissions and mistakes in maintaining the required level of biosecurity usually lead to the onset of disease, reduction in production volume, death, and loss of earnings, thus endangering the survival of the herd (Bojkovski i sar, 2005(Bojkovski i sar, , 2015.…”

Biosecurity, welfare, good manufacturing practice and risk analysisat critical control points are very important elements for intensive pig production.Planned application of biosecurity measures is crucial for the protection of pighealth and production success. In order to have an ongoing active relationship withthe existing threats it is recommended to influence the employees’ awareness ofthe real need to protect production as a whole. The key to achieving these goals areprepared biosecurity plans for each specific situation, or a specific pig farm.

“…There is a high risk of neonatal diseases, and preventive and prophylactic measures against diarrhea and pneumonia are critical. For the 4–10 days after weaning, diarrhea caused by colibacillosis is very common (Zamora, Reinhardt, Polette, & Macias, ); the extrinsic causes are the sudden deprivation of maternal antibodies due to diet changes as well as variations in temperature, humidity and other environmental conditions that affect the immune system of the animal (Bojkovski, Vasiljević, Stojanović, & Rogožarski, ). During the fattening phase (after weaning), swine dysentery is another problem, so the use of antibiotics is a common practice to avoid this issue.…”

Practical evidence suggests possible beneficial effects with the combined use of prebiotics and probiotics which can improve production parameters. The objective of the study was to investigate the addition of Saccharomyces cerevisiae (SC) as prebiotic and the combination of Lactobacillus spp. (L), Bacillus spp. (B) as probiotics on productive parameters and economic feasibility. Four hundred male pigs, hybrids of commercial genetic lines (Pietrain), were used: T1 = control group, T2 = 4 kg/tonne SC, T3 = 0.8 kg/tonne feed L and B, T4 = 4 kg/tonne SC + 0.8 kg/tonne L and B. Productive parameters were recorded in the treatment groups for four periods. Then, the viscera of five pigs per treatment were collected after slaughter to evaluate the histological changes and cytokine concentrations in the ileum. The weight gains of groups at 70-100, 100-125 and 125-150 days in the T4 group showed statistically increases (p < .05). Feed intake had a significant difference (p < .05) in T3 versus T1. The feed-conversion ratio improved for all periods in the T4 group (p < .05). The eosinophil, mononuclear infiltration and cytokines (tumor necrosis factor-α and interleukin-6) in the mucosa were lower for treatments with probiotics. In conclusion, there was an economic benefit when using both prebiotics and probiotics in the diet of pigs from weaning to finishing.

“…Nowadays, there are a lot of diseases of bacterial, viral or parasitic etiology which may endanger health status and reproduction of animals and therefore complete pig production in intensive rearing. By applying of prophylactic and therapeutic measures along with increased supervision of professional services, it is possible to keep under control all these diseases (Bojkovski et al, 2014).…”

The main goal of commercial pig production is to produce as much fattened pigs per sow per year as possible. Artificial insemination serves to enable maximum utilization of animal genetic potential. That is possible to achieve by applying adequate and controlled conditions of housing, care, feeding and health monitoring along with implementation of modern management. Expected production results on healthy farms implies farrowing rate of over 90% with 18 born piglets, 16 weaned piglets per liter, 37 piglets per sow per year and 31 fattened pigs per sow per year. Such results are achieved on modern farms in countries which invest a lot in pig production, but in Serbia are rarities. By analyzing of all factors which may cause reproductive problems on farms, we concluded that reproduction results can be improved by modern solutions from the domain of boar exploitation and technology of semen production. Motility and viability of spermatozoa to a large extent determine the quality parameters of sperm. Spermatozoa should be moved from the place of ejaculation through the reproductive tract of sows to the site of fertilization and to be capable to fertilize the oocytes at the right moment. Percentage of dead and deformed spermatozoa is an important factor which influences fertilization ability of boars. Besides routine macroscopic assessment and microscopic examination of semen, it is recommended to do smears and determine pathological forms of spermatozoa. It allows that bad quality semen can be excluded timely. Implementation of proper hygienic measures with the use of disposable equipment is required. By applying of all this specified measures during 12 months, we achieved improving of sows' conception rate for 7% and the number of weaned piglets per litter increased for 0.6.
