Abstract

Abstract:

The aim of this study was to investigate the effects of different dietary metabolizable energy and standard ileal digestible lysine levels on the lactation performance, milk components, apparent digestibility of nutrients, energy and nitrogen metabolism markers in serum, fecal microbiota, and growth performance of piglets in high-producing Shenxian sows. Sixty multiparous Shenxian sows with a total litter size of at least 11 piglets were randomly divided into six groups of ten replicates each, with one pig per replicate. A 2×3 factorial design was used, with two metabolizable energy (ME) levels (13.46 and 13.72 MJ·kg^-1) and three standard ileal digestible lysine (SID Lys) levels (0.65%, 0.85%, and 1.05%), resulting in six treatments. The experiment lasted for 35 days from parturition to weaning. The results showed that the body weight loss and backfat loss of lactating sows were significantly reduced when the dietary energy was 13.72 MJ·kg^-1 ME (P < 0.05), and the average daily gain (ADG) and weaning survival rate of piglets were significantly increased (P < 0.05), with the above indicators being optimal at 0.85% SID Lys. The apparent digestibilities of dry matter (DM), crude protein (CP), ether extract (EE) and gross energy (GE) of lactating sows were significantly improved in the 13.72 MJ·kg^-1 ME group (P < 0.05). The digestibility of crude protein (CP) in sows fed 0.65% SID Lys was significantly lower than that of the other two groups (P < 0.05). The levels of lactose and fat in milk were significantly increased with rising dietary ME (P < 0.05), and the highest level of milk protein was observed in the 0.85% SID Lys group (P < 0.05). The serum triglyceride (TG) concentration of lactating sows was significantly increased (P < 0.05), while the creatinine (CRE) concentration was significantly reduced in the 13.72 MJ·kg^-1 ME group (P < 0.05). The blood urea nitrogen (BUN) level showed a parabolic change with lysine level increased (P < 0.05). The energy level of 13.72 MJ·kg^-1 ME resulted in a significant increase in Streptococcus abundance (P < 0.05), while Turicibacter and Romnoitsia decreased significantly (P < 0.05), and Clostridium_T showed a linear decrease with increasing lysine concentration (P < 0.05). In conclusion, the dietary energy level of 13.72 MJ·kg^-1 ME and the lysine level of 0.85% SID Lys in high-producing Shenxian lactating sows ensures excellent body condition, accelerates energy metabolism and nitrogen metabolism of the body, ensures high-quality milk components, improves the intestinal micro-ecological environment, and promotes growth of the piglets.

Key words: metebolizable energy, standard ileal digestible lysine, lactating Shenxian sows, performance, milk composition
