Abstract

The research was aimed to evaluate the inclusion effect of dahlia tubers inulin (DTI) combined with Lactobacillus sp. in dietary protein step down on villi development and growth of KUB chicken. The experiment was arranged in a completely randomized design using 160 birds of one-day-old KUB chicks (body weight was 26.32±1.19 g) divided into 5 treatments with 4 replications. The treatment applied were: (1) P180S: ration with 18% protein with the addition of 1.2% DTI and 1.2 mL (108 cfu/mL) Lactobacillus sp. provided since one-day-old, (2) P15: ration with 15% protein without DTI and Lactobacillus addition and was given from 8-day old, (3) P18: ration with 18% protein without DTI and Lactobacillus addition and was given from 8-day old, (4) P15S: ration with 15% protein with the addition of 1.2% DTI and 1.2 mL Lactobacillus sp. offered from 8-day old, and (5) P18S: ration with 18% protein with the addition of 1.2% DTI and 1.2 mL Lactobacillus sp. offered from 8-day old. The experimental birds allocated in the treatments 2 to 5 were fed ration with 21% protein from hatching until 7-day old. Variables observed were the jejunal pH, total Coliform and lactic acid bacteria (LAB), villi height, protein digestibility, final body weight, and carcass percentage. Data were subjected to analysis of variance (ANOVA), and followed by orthogonal contrast test. Orthogonal contrast test showed that feeding 18% dietary protein fortified with a combination of 1.2% inulin dahlia tuber and 1.2 mL Lactobacillus sp. given since one-day-old significantly (P<0.05) affected the height of jejunal villi, protein digestibility, carcass percentage, final body weight, jejunal pH, and Coliform number. In conclusion, feeding 18% dietary protein fortified with a combination of 1.2% of inulin dahlia tuber and 1.2 mL of Lactobacillus sp. since one-day-old increases the height of the jejunum villi and growth of KUB chicken.

Abstract

The purpose of the study was to examine the supplementation effects of glucomannan extracted from a porang tuber (GEPT) on body resistance and growth performance of broiler chickens. A total number of 160 one-day-old broiler chickens with the average body weight of 42.39±0.58 g was kept for 35 days. The study was arranged in a completely randomized design with 5 treatments and 4 replications (8 birds each). The dietary treatments were T0= basal ration, T1= basal ration with the addition of 0.05% GEPT, T2= basal ration with the addition of 0.1% GEPT, T3= basal ration with the addition of 0.15% GEPT, and T4= basal ration with the addition of 0.2% GEPT. Parameters measured were the population of lactic acid bacteria (LAB), Coliform count, relative weight of lymphoid organs (bursa fabricius and spleen), heterophils-lymphocytes (H/L) ratio, body weight gain, feed consumption, feed conversion ratio, and mortality. Data were subjected to analysis of variance (ANOVA) and continued with Duncan Multiple Range Test (DMRT) at 5% probability. The results showed that supplementation of the diets with GEPT significantly increased (P<0.05) LAB population, decreased (P<0.05) Coliform count in the jejunum and ileum, and H/L ratio, but did not affect the relative weight of lymphoid organs, and growth performance. In conclusion, diet added with 0.1% GEPT improved the balance of intestinal microflora and increased body resistance, without any negative effects on the lymphoid organs and growth performance of broiler chickens.

Abstract

The study aimed to investigate the effect of dietary administration of Acalypha australis L. leaf extract, whey powder, or a combination of both on the growth, physiological condition, and carcass traits of broilers. A total of 392 broiler chicks was divided into four groups based on a fully randomized design, including (1) control (C, basal feed without additives), (2) basal feed supplemented with 1% Acalypha australis L. leaf extract (AALE), (3) basal feed with 1% whey powder (WHEY), and (4) basal feed with 1% Acalypha australis L. extract and 1% whey powder (AALEWHEY). Samples (i.e., internal organs, blood, intestinal digesta, small intestinal segments, and breast and thigh meats) were collected on day 33. Data were treated with an analysis of variance followed by Duncan’s multiple analysis. Treatments did not affect body weight, feed intake, and feed conversion ratio (p>0.05). Abdominal fat was higher in the treated broilers than in the control (C) (p<0.05). The serum high-density lipoproteins (HDL) were lower in AALE, WHEY, and AALEWHEY groups than in the control (C) (p<0.05). Serum creatinine concentrations were higher in WHEY and AALEWHEY groups than in C and AALE groups (p<0.05). The AALE, WHEY, and AALEWHEY groups had higher duodenal villi height than C group (p<0.05). The villi height to crypt depth ratios were higher in the jejunum of the WHEY and AALEWHEY group than in the C group (p<0.05). The pH of breast meat was higher in the C group than in AALE and AALEWHEY groups (p<0.05). The lightness values of breast meats were lower in the AALEWHEY group than in the other groups (p<0.05). The redness values of breast meats were lower in the C group than in the AALE, WHEY, and AALEWHEY groups, while the yellowness values were lower in C and AALE groups than in WHEY and AALEWHEY groups (p<0.05). The pH values of thigh meats were higher in the AALE group than in control (C), WHEY, and AALEWHEY groups (p<0.05). In conclusion, the treatment of broilers with leaf extract of Acalypha australis L., whey powder, or a combination of both improved intestinal morphology and meat quality without affecting the growth performance of broilers.
