The aim of this field study was to evaluate the influence of the probiotic BioPlus 2B on the weight loss of sows during lactation and weaning weight of litter and piglets. A total of 126 gilts/sows on commercial pig farm were allocated to either group of 61 sows supplemented with probiotic BioPlus 2B 400 g per ton or a non-supplemented control group of 65 sows from two weeks before farrowing to weaning. Microbiological contents of feed rations were analyzed. Data were statistically processed by MS Excel program package using methods for descriptive statistics, analysis of variance and t-test. Lactating sows supplemented with probiotic BioPlus 2B increased their feed intake. It reduced sows weight loss during lactation; weight loss was 40.4-44.8 kg in controls versus 18.0-23.0 kg in supplemented sows (p 〈 0.05). Insemination of sows was done 4-5 day after weaning. Repeated insemination was needed for more sows in control group-22 sows in the control group vs. 12 sows in the supplemented group (p 〈 0.05). Reduce percent of repeated insemination from 36% to 18.5% in a commercial pig farm is a notable effect. The number of weaned piglets/litter is not significantly different between control and supplemented groups (10.54 piglets versus 10.63, p 〉 0.05). Weaned litter weight was 85.2 kg in control group and 83.4 kg in the supplemented group (p 〉 0.05). It concludes that these are sound arguments to supplement all sows on commercial farm with BioPlus 2B. 展开更多
