摘  要：
This study was to assess the effect of fermented rapeseed meal (FRSM) in the diet of sows, taking into account the physiological period (pregnancy or lactation) and reproductive cycle (primiparous or multiparous sows), on production performance, nutrient digestibility, colostrum immunoglobulin content, and microbial flora in sows. The experimental material included 30 primiparous gilts and 30 multiparous sows after their second lactation. The animals in the control groups C(G) (gilts) and C(S) (sows) received a standard diet for pregnant or lactating sows, depending on the reproductive period. Experimental groups E(G) and E(S) comprised gilts and multiparous sows, respectively, receiving a diet with a 4% share of FRSM in place of soybean meal up to 100 d of gestation. In addition, from 100 d of gestation to 7 d of lactation, the sows in experimental groups received a diet with a 9% share of FRSM, and then again a diet with a 4% share of FRSM until the end of lactation. The addition of 4% to 9% share of a FRSM component in feed significantly improves production parameters, mainly in primiparous gilts, leading to an increase in litter size and in litter weight at 28 d of age. It also helps to improve the digestibility of crude protein, fat, and crude fiber, and positively affects the gut microbiota of sows. Fermentation of rapeseed meal is an effective way to reduce anti-nutrients and to increase the level of lactic acid in the diet. It also stimulates the immune system, which improves piglet health, reducing the severity of diarrhoea and mortality.
