Abstract
Abstract: Fermentation has been practice to bioconvert inorganic substances into more readily available nutrients. Selenium is an important trace mineral functioning to improve growth and health status. A study was carried out to determine the carcass percentage and organ development of broilers fed fermented diets with the addition of selenium. Rice bran from the local market was purchased and finely ground. One kg rice bran added with 1 g sodium selenite as surce of selenium (Se) was autoclaved for 20 minutes at 20 psi. The autoclaved rice bran was added with distilled water up to 80% moisture concentration. The autoclaved mixture was incubated with two different fungi (Aspergillus niger and Saccharomyces cerevisiae) for 120 hours to produce fermented rice bran with A. niger (FRBAN) and fermented rice bran with S. cerevisiae (FRBSC). The study used 140 day-old-chicks as experimental animals. The birds were kept in cages for 6 weeks and fed 5 different diets ad-libitum. The treatments were control basal diet (T-1), control + 0.4 ppm Se (sodium selenite; T-2), control basal diet + 0.4 ppm Se from Selplex commercial feed additive rich in Se (T-3), control diet + 0.4 ppm Se derived from FRBSC (T-4) and control basal diet + 0.4 Se derived from FRBAN (T-5). A completely randomized design was adopted in this study with 5 treatments and 4 replications. Results of the study indicate that percentages of liver, gizzard, and carcass were lower in birds fed diets containing sodium selenite. Shorter relative length and diameter of the small intestine were also found in the birds offered the sodium selenite – supplemented diet. The percentages of abdominal fat and breast muscle were not affected by treatment diets. In conclusion, the addition of Se in the form of sodium selenite negatively affected percentages of the liver, gizzard, carcass and digestive tract dimensions. Fermentation of rice bran containing sodium selenite could minimize the detrimental effect of inorganic selenium.

Abstract
Abstract The low quality protein of coconut meal, coupled with high fibre content, leads to limited use of this agricultural by-product in the poultry diet. Attempts to maximize the amount of coconut meal included in the broiler feed have been made through amino acids supplementation, enzyme addition and pelleting coconut meal. Among these feed technologies and manipulation, pelleting coconut meal appears to be more powerful in promoting the growth of broiler chickens. The reasons for the improvement of broiler growth due to pelleting coconut meal have not been established yet. The mechanisms of improved growth of birds might be through increased feed intake, less energy spent and increased bulk density. Coconut meal contains a high concentration of mannose – based polysaccharides or mannan. This substance has long been believed to have prebiotic properties due to its capability to bind certain species of pathogenic bacteria in the digestive tract of birds. Voluminous reports of the positive effects of mannose-based polysaccharides from yeast have been published. Mannose –based polysaccharides from legumes, on the other hand, have been reported to have anti-nutrient property. Surprisingly, mannose-based polysaccharides from coconut behave like yeast mannan. A number of current studies indicated that mannose based polysaccharides improved body weight gain and feed digestibility. The growth of birds was negatively impacted when the birds were challenged against pathogenic bacteria of E. coli. Wet droppings and diarrhea incidences were not found in E. coli-challenged birds when the diets were supplemented with coconut mannan. In conclusions, coconut meal can be used as a feed ingredient for poultry unless the coconut meal was pelleted or enzymatically treated. Mannose-based polysaccharide from coconut was effective to promote growth and acted as prebiotic.

Abstract
One alternative approach can be done to replace the antibiotic growth promotant function (AGP) in broiler, which is the use of probiotic microorganisms. The aim of this study was to look at the effects of probiotics on Lactobacillus paracasei on hematological conditions and lymphoid organs. This study used a completely randomized design consisting of 4 treatments with 5 replications, each replication using 4 broiler chickens. Treatment consists of controls (0 mL/day), Probiotics 1 mL/day, Probiotics 3 mL/day, and Probiotics 5 mL/day. The probiotics used in this study, namely Lactobacillus paracasei (5.8 x 107 CFU/mL) were given through drinking water. The results showed that the treatment had no significant effect (P>0.05) on the number of erythrocytes, hematocrit percentage, hemoglobin level, number of leucocytes, and erythrocyte index. Likewise, treatment had no significant effect (P>0.05) on the relative weights of bursa fabricius, thymus, and spleen exchanges. The values shown in hematology parameters are all within the normal range. Whereas in the lymphoid organ parameters there is a tendency for the relative weight of lymphoid organs to be greater in the treatment of Lactobacillus paracasei than in controls. Probiotics Lactobacillus paracasei used in this study did not respond poorly to hematological features and can be used as an immunomodulator in broilers.

Abstract
Abstract The study was conducted to examine effects of supplementation of crude cellulase produced from Trichoderma viride – fermented copra meal (CM) on nutrient digestibility, apparent metabolizable energy (AME), digestive organs weight, protein and cholesterol content of breast meat of broiler chickens. A total of 200 day-old-male broiler chickens were used. The birds were fed with 5 different diets; T-1 = 0 g/kg CM, T-2 = 50 g/kg CM + crude enzymes, T-3 = 100 g/kg CM + crude enzymes, T-4 = 150 g/kg CM + crude enzymes and T-5 = 200 g/kg CM + crude enzymes. Feed digestibilities, digestive organs weight, protein and cholesterol content of breast meat were determined as parameters. On day 35, two birds from each replication were placed into metabolisme cages for digestibility measurement. A completely randomized design was adopted with five treatments and five replications. The digestibilities of protein, crude fibre, AME of the diets and cholesterol content of the breast meat of broiler chickens fed the rations with crude enzymes addition were better than those of birds fed the T-1. The response of protein and crude fibre digestibilities were curvilinearly over the increasing levels of CM in the diets and crude enzyme addition. Digestive organs weight, protein and lipid percentages of the breast meat were not affected by the treatments. Supplementation of increasing CM diets with crude enzymes from Trichoderma viride produced higher protein, crude fibre digestibilities and AME of the diets and lower cholesterol content of breast meat

Abstract
In the first days after hatch, the development of organs such as the gastrointestinal tract, and the growth performance may be affected by the time in between hatch and first feed intake. In current practice, time between hatch and moment of first feed intake may take long time because of variation in hatch time, chick handling, and transportation time. Feed deprivation, especially during the first days after hatch, depresses intestinal development on the short and long term, reflected by a lower intestinal weight, shorter length, lower enzymatic activity, altered villi and crypt cell density, and lower crypt depths and villi heights and finally, depressed growth. The objective of this study is to investigate effects of the moment of first feed intake after hatch on intestinal development and growth performance of broiler chickens. Total 60 unsexed day-old Lohmann broiler chicks were randomly assigned into 3 treatments of 20 chicks each in four replicates (5 chicks each). The treatments were time first feed and water access after hatch, including 12, 42 and 72 hours. Body weight gain and feed intake were recorded weekly and the intestinal development were sampled at 12 days for the measurement of ileum histology and 38 days for length of gastrointestinal tract. Results obtained are as follows: Time between hatch and moment of first feed intake had no significant effect (P> 0.05) on width of the villi. However, the height of villi, depth of the crypt dan length of the gastrointestinal tract were significantly affected by treatment. The longer delay in the provision of feed and water in day-old chick were lower height of villi and depth of the crypt, dan shorter length of the gastrointestinal tract. Statistically, performance parameters had any difference among treatments, except for feed convertion. The final body weight and feed intake decreased with increasing time between hatch and moment of first feed intake. The results suggest that development of the gastrointestinal tract improved growth performance of broiler chickens.

Abstract
The high crowding level of the coop causes chicken body weight gain to be smaller than those with low coop crowding level. This study aims to analyze the coop crowding level to the performance of Kampung-Broiler (KB) cross-breeding chicken. The research was conducted from February to June 2019, in the Field Laboratory of Animal Husbandry Department at Agriculture Faculty, Asyariah Polewali Mandar University. Using Randomized Block Design (RBD) in the treatment of KB cross-breeding coop crowding level with 3 groups and each group contained 8, 10, and 12 KB chickens. Each treatment will be repeated 3 times each. Reared in a 1x1 m2 chicken coop. The results showed that the crowding of the coop had a significant effect (P <0.05) on feed consumption, weight gain and feed conversion. Feed consumption was significantly lower in the P0 treatment that was 974.53 g/chicken and the highest was P2 (1379.29 g/chicken). The highest weight gain was in P0 with 1334.77 g/chicken and the lowest was in P2 with 1237.54 g/chicken. The lowest conversion value was at P0 with 0.73 and the highest was at P1 (1.11 g/chicken). Based on the results of this study it can be concluded that the best treatment is P0 characterized by low consumption, high body weight gain and low conversion.
