The purpose of this test was to study the digestible lysine requirement for Duroc?Luyan White hybrid weaner piglets. Firstly, six Duroc?Luyan White piglets with an average body weight of (35.00?1.25) kg were selected,and according to the variety of experiment materials, 7 kinds of semi-purified dietary were formulated, which used to determine the ileal apparent amino acid digestibility of feeds by digestion experiment. Secondly, a total of 120 Duroc?Luyan White hybrid weaner piglets (half barrows and half sows) at (35?2) days of age with an average initial body weight of (9.13?1.61) kg were used in this test. According to the results of previous test and the dietary digestible lysine levels (0.90%, 1.00%, 1.10% and 1.20%), the piglets were divided into 4 groups, and each group had 6 replicates (3 barrows sties and 3 sow sties) with 5 piglets each. The results showed as follows: 1) for all experimental piglets,compared with 1.00% group, the feed/gain (F/G) in 0.90%,1.10% and 1.20% groups was increased by 3.24% (P<0.01), 4.24% (P>0.05) and 11.32% (P<0.01), and average daily gain (ADG) was decreased by 15.82% (P<0.01), 4.55% (P>0.05) and 9.74% (P<0.01). 2) For barrows and sows, compared with 0.90% and 1.20% groups, ADG in 1.00% group was significantly increased (P<0.05). Compared with 1.20% group, average daily feed intake (ADFI) in 1.00% group was significantly increased (P<0.05). For barrows, the F/G in 1.00% group was lower than that in 0.90% and 1.20% groups, but there was no significant difference for sows (P>0.05). 3) For all experimental piglets and sows, serum urea nitrogen content in 1.00% group was significantly lower than that in 1.20% group (P<0.05). For all experimental piglets, barrows and sows, the plasma total protein content had no significant difference among all groups (P>0.05). The results show that the digestible lysine requirement for Duroc?Luyan White hybrid weaner piglets (10 to 20 kg) is 1.00%, and sex factor has no significant effect on digestible lysine requirement.
