Ayam salah satu sumber protein yang mudah didapat. Pakan alternatif seperti ampas kelapa fermentasi digunakan untuk mengurangi biaya pakan. Penelitian ini dilaksanakan dengan tujuan untuk mengetahui tinggi vili pada tunika mukosa dan jumlah kelenjar liberkuhn pada ayam broiler yang telah diberikan pakan tambahan ampas kelapa fermentasi. Penelitian ini menggunakan 36 ekor ayam broiler. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 6 perlakuan dan 6 pengulangan. Perlakuan terdiri atas PO: 100% pakan komersial tanpa substitusi tepung ampas kelapa, P1: 90% pakan komersil ditambah 10% ampas kelapa fermentasi, P2: 80% pakan komersil ditambah 20% ampas kelapa fermentasi, P3: 70% pakan komersial ditambah 30% ampas kelapa fermentasi, P4: 60% pakan komersial ditambah 40 % ampas kelapa fermentasi, P5: 50% pakan komersial ditambah 50% ampas kelapa. Perlakuan dilakukan pada ayam usia 15 sampai 35 hari. Ayam dipanen dan disembelih. Kolon dipotong dengan ukuran 1x 1x 1 cm, dimasukan ke dalam NBF 10%. Dilakukan rangkaian pembuatan preparat histologi dan pewarnaan dengan hematoxilin eosin. Parameter yang diamati adalah jumlah kelenjar liberkuhn dan tinggi vili. Data dianalisis menggunakan ANOVA. Hasil dari penelitian menunjukan bahwa ampas kelapa fermentasi pada setiap perlakuan dengan 10%, 20%, 30%, 40%, dan 50% tidak memiliki perbedaan yang nyata (P˃ 0.05) terhadap tinggi vili dan jumlah kelenjar liberkuhn ayam broiler. Dapat disimpulkan bahwa pemberian ampas kelapa fermentasi pada pakan tidak mempengaruhi tinggi vili dan kelenjar liberkuhn.

Chicken is an easy source of protein. Alternative feeds such as fermented coconut pulp are used to reduce feed costs. This research was carried out with the aim of knowing in the area of the intestinal mucosa and the number of liberkuhn glands in broiler chickens that had been given additional feed of fermented coconut pulp. This study used 36 broiler chickens. The design used was a Completely Randomized Design (CRD) with 6 treatments and 6 repetitions. The treatments consisted of PO: 100% commercial feed without substitution of coconut pulp flour, P1: 90% commercial feed with 10% fermented coconut dregs, P2: 80% commercial feed with 20% fermented coconut dregs, P3: 70% commercial feed with 30% fermented coconut dregs, P4: 60% commercial feed with 40% fermented coconut dregs, P : 50% commercial feed with 50% coconut dregs. The treatment was carried out on chickens aged 15 to 35 days. Chickens are harvested and slaughtered. The colon was cut with a size of 1 x 1 x 1 cm, inserted into the 10% NBF. A series of histology preparations and staining with hematoxylin eosin were performed. The parameters observed were in the liberkuhn glands and the area of the large intestine mucosa. Data were analyzed using ANOVA. The results of the study showed that fermented coconut pulp in each treatment with 10%, 20%, 30%, 40%, and 50% had no significant difference (P ˃ 0.05) on the area of the intestinal mucosa and the number of liberkuhn glands in broiler chickens. It can be concluded that the application of fermented coconut dregs to the feed did not affect the area of the intestinal mucosa and liberkuhn glands.
