Effect of probiotics in the piglet feeding A research, using post-weaning piglets, was carried out to evaluate the effects of probiotic Biomate 2Bpuls, containing in equal parts Bacillus subtilis and Bacillus licheniformis. Forty animals weaned at an a average age of 28 ± 0,25 days were divided into four homogeneous groups according to age, weight, sex, genotype of provenience and were housed in individual flat-deck cages of 0,48 m2 and supplied with a holed plastic floor. The cages, were put in a common room and were provided with feed trough and nipple drinker. The animals were fed ad libitum with the following diet: group C (standard diet, control group), group A (standard diet added with probiotic at 400 g/ton), group P700 (standard diet with probiotic at 700 g/ton). The trial went on for 42 days, each tow weeks the animals were singularly weighed and at the same time feed consumption was verified. During the last week of the experiment, on five animals in each group, the ingesta-excreta balance was carried out with the grab-sampling method, using the insoluble ashes as internal indicator. Moreover, during the last day of experimentation, on four animals in each group blood samples from jugular vein and faeces from rectal canal were taken to perform haematic and microbiological analysis respectively. The results of breeding performance, all through the trial, pointed out that the average daily weight gain ranged from 527 g/d (group C) and 548 g/d (group P400), with a significant difference for P<0,05, while for feed efficiency the limit values were 1,99 (group A) and 1,92 (group P700). The slight better results were furnished by piglets fed with probiotic. The letter results agree with those obtained from the digestibility trial, where the digestive employ of dry matter, organic matter and energy was slightly better in P400 and P700 groups. The microbiological analysis of faeces pointed out the great reduction of lactobacillis and coliforms, due to the ingestion of probiotic. As to haematic parameters, there emerged the absence of any effects of probiotics on triglycerids and colesterol values. Finally, the health status of piglets was good, as witnessed by the absence of diarroic events and survival of all animals.

Abstract
Effect of probiotics in the piglet feeding A research, using post-weaning piglets, was carried out to evaluate the effects of probiotic Biomate 2Bpuls, containing in equal parts Bacillus subtilis and Bacillus licheniformis. Forty animals weaned at an a average age of 28 ± 0,25 days were divided into four homogeneous groups according to age, weight, sex, genotype of provenience and were housed in individual flat-deck cages of 0,48 m2 and supplied with a holed plastic floor. The cages, were put in a common room and were provided with feed trough and nipple drinker. The animals were fed ad libitum with the following diet: group C (standard diet, control group), group A (standard diet added with probiotic at 400 g/ton), group P700 (standard diet with probiotic at 700 g/ton). The trial went on for 42 days, each tow weeks the animals were singularly weighed and at the same time feed consumption was verified. During the last week of the experiment, on five animals in each group, the ingesta-excreta balance was carried out with the grab-sampling method, using the insoluble ashes as internal indicator. Moreover, during the last day of experimentation, on four animals in each group blood samples from jugular vein and faeces from rectal canal were taken to perform haematic and microbiological analysis respectively. The results of breeding performance, all through the trial, pointed out that the average daily weight gain ranged from 527 g/d (group C) and 548 g/d (group P400), with a significant difference for P<0,05, while for feed efficiency the limit values were 1,99 (group A) and 1,92 (group P700). The slight better results were furnished by piglets fed with probiotic. The letter results agree with those obtained from the digestibility trial, where the digestive employ of dry matter, organic matter and energy was slightly better in P400 and P700 groups. The microbiological analysis of faeces pointed out the great reduction of lactobacillis and coliforms, due to the ingestion of probiotic. As to haematic parameters, there emerged the absence of any effects of probiotics on triglycerids and colesterol values.
