Basco S. Resistance and productivity of pigs under the influence of abiotic and biotic factors

Based on the assessment of sanitary and hygienic condition of piglets with different capacities, productive qualities of sows and nonspecific resistance piglets, it was found that the greatest value of the complex index of reproductive qualities of sows (111,94 ± 5,59) and resistance index of piglets - IR (162,96 ± 8,14) was detected in the animals maintained at the high performance index of sanitary and hygienic well-being - J (0,78-1,00). The triple injection of immunostimulatory medications of Gamavite, Katozal and Timogen for piglets with congenital deficiency of body weight contributed to its increase. The use of medications contributed to increase of non-specific resistance of hypotrophic piglets, as was evidenced by an increase in blood serum total protein content, ?-globulin and circulating immune complexes. Dyspepsia disease which piglets of 15 days have had, adversely affected their safety and morbidity in the future, as well as the amount of body weight. Safety of pigs up to 4 months of age was lower by 22-49 %, the incidence - up to 25,8-38,0 %, body weight - reduced by 14,9-31,1 %. Despite the use of immunomodulators of Ribotan and Levamisole, the impact of "diarrhea" stress is evidenced by the indicators of content of erythrocytes, leukocytes, hemoglobin, total protein, albumin, globulin, FAN. Sarcoptic mange causes a strong biological stress on the organism of pigs. In pigs of young growth sarcoptic mange appears through depression of growth, a lower content of lymphocytes, albumin, ?-globulin in blood, which indicates the need to implement sanitary and hygienic measures of prevention of this disease. Group maintenance of lactating sows of four or two contiguous litters or of four nests can be an alternative way of keeping animals on farms under impossibility of use of the individual boxes. The feasibility of this method is evidenced by the absence of significant difference with the indicators of keeping animals in individual box on the parameters of body weight, keeping, morbidity of pigs, blood content of hormones of stress state (cortisol and thyroxin), T- and B-lymphocytes and the circulating immune complexes.
