[Experimental studies on a decrease in hypotrophy in newborn piglets in commercial swine raising].

The birth of hypotrophic piglets with 2-3 times lower live weight than the normally born ones, which die till the 40th hour, because of the abruptly decreased vitality is described. Their percent is 7 for the reproductive bases and 10 for a commodity swine breeding complex. Studies were carried out on 402 pregnant pigs, treated with protein hydrolysate and glucose (injected) together with vitamin-mineral additions to the forage. For a control were used 395 pregnant pigs under the same conditions, but not treated with the above mentioned medicines. A two fold decrease of the birth of hypotrophic piglets was achieved. The rest of the pigs are with a higher live weight and vitality which is the reason of their suffering from coli bacteriosis and other diseases of the conditions at a considerably lower extent. It is supposed that the irreplaceable (limited) amino acids are at the base of that biological phenomena for the prophylaxis of the hypotrophy in the pathology of the hybrid industrial swine breeding. That model scheme as a method can be realized in reproductive and nuclear bases for hybrid swine breeding because of its undeniably great and economic effect.

[Case of MD-VD in cattle].

An enzootic is described of the classic form of virus diarrhea mucosal disease on a newly organized farm for heifers. The disease ran a sporadic course, mainly with intrauterine infections, while with the calves it was recorded as an enzootic with 100 per cent morbidity rate and 28 per cent mortality rate. The clinical picture was complicated--in some calves the disease started with fever, in other respiratory distrubances were observed, while in a third group diarrhea was prevailing. A detailed description is given of the clinical symptoms and the morphological lesions. A virus was isolated, identified as a virus of the mucosal disease--virus diarrhea. A virus antigen was likewise demonstrated by the gel precipitation test after Wachendorfer and Darbyshire, modified by Haralambiev. Various agents were used for treatment. Better results produced the strain K vaccine against swine fever in combination with semiliquid agar.
