A ll sow s had ad2lititum access to feed and w ater. 0, 40, 60, 80, 100, 120 ggkg alfalfa s w ere respectively added to 6 group s. T he experim en t w as conducted in o rder to study the effects of adding differen t alfalfa s to lactating diet on perfo rm ance and serum item s of sow s and their p iglets, and m ilk compo sition. T he resu lts show ed that: (1) T here w ere no sign ifican t difference in in terval betw een ab lactation and oestru s (P > 0. 05) ;W ean ing p iglets and su rvival rate w ere sign ifican tly imp roved du ring lactation period w hen amoun t of alfalfa w as increased (P < 0. 05) ; Feed in take du ring the lactating sow s, w ean ing litter w eigh t, litter w eigh t gain, w ean ing average individual w eigh t and average individual daily w eigh t gain of p iglets w ere sign ifican tly enhanced (P < 0. 01). (2) Serum cho lesterin, triglycerides and low er den sity cho lesterin concen tration of sow s w ere decreased, and at the sam e tim e, the level of serum h igh den sity cho lesterin of sow s and in su lin of sow s and p iglets w ere increased becau se of adding alfalfa to lactating diet, bu t no sign ifican t difference w as ob served in them (P > 0. 05). (3) In su lin2like grow th facto r in m ilk of sow s w as imp roved to a certain ex ten t, bu t there w as no sign ifican t difference (P > 0. 05). T he study show ed that adding alfalfa to diet of sow s imp roved the perfo rm ance of lactating sow s and suck ling p iglets and the effect w as sign ifican t w hen additive amoun t cam e to 100 gg kg. So it w as recomm ended that the su itab le additive con ten t of alfalfa in diet of later p regnancy and lactatiing sow s w as 100 ggkg.
