A trial and pig performance data collection was conducted to evaluate the efficiency of Luodong Bio- Fermentation Treatment Technology with zero discharge effect in a pig close house system at Tanjung Sepat, Selangor. This trial was done to gather and monitor the pig growth performance and the pig acceptance of using the Loudong Bio-fermentation Waste Treatment Technology in close house enviroment. Growth performance of the pigs were monitored by an average daily gain, feed conversion ratio, behaviour and veterinary observations. Close house temperature, moisture measurement and
bedding sampling were also conducted.

Belarus is included into number of the leading countries of the world which provide the increasing of the expansion rates of milk production and dairy products on a per capita basis. However, the agricultural enterprises of the Republic of Belarus annually spend approximately 800 thousand tons of whole milk that makes about 20% from the general milk yield for manufacturing expenditures in the process of livestock operation. The purpose of research was working out of a new premix structure and zootechnic requirements to its use in structure of milk replacer, produced on hydrodynamic installation. The optimum doses of amino acids, vitamins and mineral substances promoted the increasing of calves daily average weight gain during the dairy period on 5,4% (788,5 g instead of 748,1 g), reducing of expenses for forages per 1 kg of weight gain - on 6,5% (2,9 fodder units against 3,1 fodder units) and the decreasing of the prime cost production for fodder expenses - on 4,7%. There was presented the composition and nutritive value of the analysed whole milk replacer. Usage of local sources of protein-fatty raw materials of plant origin, and also secondary resources of processing of whole milk in the content of milk replacer for young cattle allows to completely refuse from expensive components delivered from abroad and to lower their cost

Research was directed towards selection of national, accessible and cheap ingredients of whole milk replacers in the conditions of the Republic of Belarus. The efficiency of compounding preparation and its use in calves feeding at an early age was analysed. There was developed the technological scheme of application of hydrodynamic installation which operates according cavitating principle and makes it possible to receive the homogeneous and finely divided mass directly from grain forage that is very important for preparation of milk replacer. New equipment gives the chance to lower power consumption on 17%, to receive economic benefit. During testing of developed of milk replacer-1 (used for calves feeding since one month old) and milk replacer-2 (used for calves feeding since two months old) and their comparison with the whole milk replacer Kalvolak (the Netherlands) it was revealed, that indices of a daily average weight gain in calves of the first group fed with foreign milk replacer, and in calves of the second groups, which were fed with the national milk replacer, did not show authentic differences (806 and 816 g). However, the prime cost of 1kg of live weight gain in the second case was on 43% cheaper than in the first one. The cost price of 1kg of live weight gain of calves on expenses for fodder units in trial group was on 33% cheaper in comparison with the control group
