Principles and results of breeding phytophthora resistant potatoes
Late blight of potato is one of the most dangerous disease. In epiphytotic years tubers yield loss can reach 50-60%. Creation of callirars with a high degree of field resistance is one of the way to solve tliis problem. In this case inheritance of criterion carries out intermediate character. That means polygenic control and complex type of gene interaction. The main method of Phytophthora resistant caltirars creation is interspecific hybridization. The sources of mentioned above resistance are wild and primitive species growing up in epiphytotic places. As a result, the caltirars with leaves and tubers resistance to Phytophthora has been received.

Optimization of mineral feedings of ruminant animals and use of local sources of raw materials
Mineral supplements from the local sources (MSLS) - gallites, phosphogypsum, and dolomites - were tasted in a series of field and metabolic trials on cattle and sheep of different ages in comparison with traditional mineral additives such as salt, sodium sulphate and magnesium oxide. It is estimated that die feeding of local sources in comparison with traditionally proposed increases the yield of milk containing 4 per cents of grease by 5,7 %, live weight gain by 2,9-4,3 %, the volume of ejaculate by 7-10, total number of sperm cells in ejaculate by 1,3-17,9, quantity of particles by 4,2-8,7 %, it reduces expenses for cattle feeding by 2,2 %, prime cost of cattle gaining by 6,4, the cost of every frozen particle by 4,2-8,2 %. Blood and rumen parameters, meat and milk qualities in experimental and control animals were within standard ranges. Rumen digestion, metabolism, live weight gains, wool production and reproductive performance of sheep were not negatively affected by MSLS.

Milk protein content of BBW cows and its relationships with other milk production traits
Information about milk protein percentage of Belorussion Black and White cows and interrelationships within milk protein percentage and other milk production parameters are given. It was found that average milk protein content was 2,90-3,14% on most farms. Average milk protein percentage was found to be dependent on average milk yield on the farm: the lower is the milk yield on the farm, the lower is the average milk protein percentage. The estimate of protein content and phenotypic correlation variability between protein percentage in milk of different protein containing and other features is given. This has made it possible to make the conclusion about the necessity of cattle selection by the criterion of protein containing in milk. Here is given the forecast how the selection by the criterion of milk yield and protein percentage in milk will effect the protein containing in milk of Belarusian Black & While cattle.

Mineral additive for fattening cattle on diets with distillers grains
A new complex mineral additive (CMA) has been formulated to balance diets based on distillers grains for fattening cattle. CKA included 41 % of gallites, 38 % of phosphogypsum, 21% of dolomite by weight supplemented with trace elements: copper, zinc, iodine and cobalt. It was found that better mineral nutrition of experimental steers resulted in better rumen digestion and nubrients digestibility by 3-4%, higfier arerage daily gains during 165 days of CMA feeding by 8% (830 g/day) and lower feed expenses by 0,8 F.U./kg of weidht gain including 0,5 F.U./of concentrates/kg of gain. The economical gain of CMA feeding to young fattening cattle was due to the lower self cost of gain by 20,6%.
