The animal model used was 54 piglets divided into three groups of treatments: the control group was given starter commercial feed, group T1 was given starter pig feed with added 1 lignocellulose fiber, and the T2 group was assigned starter feed with the additional 2 lignocellulose fiber. Treatment is given for 4 weeks starting at 41–68 days old. Health observations were also carried out during the research. Piglet performance is determined based on feed intake, body weight and feed conversion ratio (FCR). Examination of the health of the gastrointestinal tract by measuring the length and weight of the intestine, microscopic length of the villi and depth of the crypts, as well as the number of Escherichia coli in the piglet’s small intestine. The research showed that adding 1 and 2 lignocellulose fiber in the feed for 28 days may increase feed intake and body weight and reduce FCR significantly. Adding lignocellulose fiber may significantly lower diarrhea incidents, and death was not found in the treatment group. Lignocellulose fiber may increase villi’s intestinal length and weight height compared with control. It can be concluded that supplementing lignocellulose fiber through feed may increase the piglet’s health growth and efficiency.
