Effects of probiotics complex supplementation in low nutrient density diet on growth performance, nutrient digestibility, faecal microbial, and faecal noxious gas emission in growing pigs

The objective of the present study was to evaluate effect supplementing low nutrient density diet growing pigs with probiotics complex on growth performance, digestibility, faecal microbial, and noxious gas emission. A total 140 crossbred female castrated male healthy [(Yorkshire × Landrace) Duroc, 54 days age] an average initial body weight (BW) 24.39 ± 2.58 kg were used in a 42-day trial. All randomly allotted one four treatment diets based BW sex (seven replicate pens/treatment; two gilts, three barrows/pen). Dietary treatments were: (i) HD, high diet, (ii) LD, (iii) T1, LD + 0.05% probiotics. (iv) T2, 0.10% At end experiment BW, daily gain (ADG), gain: feed ratio (G: F) tended be higher (p < .1) HD compared treatment. However, supplementation showed comparable as that diet. There no differences > .05) intake (ADFI), backfat thickness, lean meat percentage, apparent tract digestibility (ATTD) dry matter (DM), nitrogen (N), energy among treatments. increased Lactobacillus counts reduced NH3 emission In conclusion, results this demonstrated beneficial effects concentration, suggesting.HighlightsTo 2 levels (0.05%, 0.1%) (Bacillus subtilis ms1, Bacillus licheniformis SF5-1, Saccharomyces cerevisiae) pigs.Probiotics has shown performance.The emission.The B.
