  Background and Objective: Broiler reared above the condition of thermoneutral zone will be vulnerable to environmental heat stress and exhibit behavioural and physiological changes. This study is to evaluate the effects of supplementation of potassium chloride (KCl) in drinking water on broiler performance and physiological responses under conditions of environmental heat stress. Methodology: A total of 200 days old broiler chicks were evaluated in this study. They were randomly divided into 20 plots and reared for 5 weeks. A completely randomized design with 5 treatments and 4 replications were assigned in this study. The treatments were symbolized as R0, R1, R2, R3 and R4, which is respectively supplemented with KCl as much as 0, 0.25, 0.50, 0.75 and 1.00% (w/v) in drinking water. Variables observed were feed and water intake, body weight gain, feed conversion ratio, the amount of potassium, sodium and chloride absorbed, mortality, the panting percentage, cloacal temperature, numbers of leukocytes and blood pH. Results: The results indicated that the supplementation of KCl in drinking water did not significantly (p>0.05) affect the panting percentage, however, significantly (p<0.05) affected the feed and water intake, body weight gain, feed conversion ratio, the amount of potassium, sodium and chloride absorbed, cloacal temperature, numbers of leukocytes and blood pH. Conclusion: It was concluded that the supplementation of 0.50% KCl in drinking water was the optimal level for improving performance and physiological response of broiler chickens under environmental heat stress condition.

  Background and Objective: Probiotics have been reported to have positive effect on gut morphology and subsequent performance of poultry birds. Therefore, the present study was carried out to evaluate the effect of fermented soy and cow milk as probiotic on small intestine morphometry of broiler chicken. Materials and Methods: 100 day old commercial broiler chicks were allocated to 4 treatment groups in a complete randomized design (CRD) and each treatment was replicated 4 times with 5 chicks in each replicate. The treatments consisted of birds fed: Only basal feed (T0), basal feed with 100% fermented cow milk (T1), basal feed with fermented cow milk+fermented soy milk in 50:50% ratio (T2) and basal feed with fermented cow milk+fermented soy milk with a 75:25% ratio (T3). Results: Use of fermented cow or soy milk as probiotic in the diet of broiler had no significant (p>0.05) effect on jejunal villus height when compared with the control group. However, there was an improvement in the jujunal villus width and number of villi in chicken fed fermented cow or soy milk as probiotic in the diet when compared with the control. Conclusion: Inclusion of dietary fermented cow or soy milk in the diet resulted in improvement in the morphometry and number of villi in the jejunum part of small intestine in broiler chicken.

  Background and Objective: The processing of waste materials from the frozen shrimp industry in the form of shrimp skins and heads has the potential to be used as an alternate feed additive in poultry ration formulas. The limiting factor for the use of shrimp waste is the presence of chitin, which binds strongly to proteins, fats and minerals through β (1-4) covalent bonds so that it is difficult to digest by chicken digestive enzymes. Waste-product bio-processing can be carried out through deprotonation stages with Bacillus licheniformis as well as demineralization with Lactobacillus sp. and Saccharomyces cerevisiae to convert materials to concentrated feed nutrient products (hereafter termed Nutrient ConcentratesBLS). This biological test of Nutrient ConcentratesBLS in ration formula was conducted to determine the effectiveness of the product in the production and quality of chicken eggs. Materials and Methods: The study was carried out using domestic laying hens on a test farm. The experimental design was completely randomized; it consisted of 6 ration treatments and each treatment was replicated 4 times. The variances of the obtained data were analysed and differences between treatments were tested with Duncan's multiple range test. Results: The results of the study were obtained: (a) Nutrient ConcentratesBLS could be stored up to 8 weeks at room temperature (pH: 7.36, ammonia: 9.60%, water content: 9.67% and energy conversion: 77.36%), (b) The laying performance of domestic hens in poultry production using Nutrient ConcentratesBLS as a feed additive at a level of 2% in the ration formula was equivalent to that of the hens fed the standard ration (egg weight 44.71 g grain–1, hen-day production 51.79% and ration efficiency 35.49%) and (c) The quality of chicken eggs from hens fed Nutrient ConcentratesBLS was better than that of hens fed the standard ration (shape index: 79.34, albumin index: 0.20, Haugh-unit: 94.11, yolk index: 0.37, yolk colour: 9.00 and egg cholesterol levels: 96.45 mg dL–1). Conclusion: Nutrient ConcentratesBLS, made from shrimp waste bioprocessed by Bacillus licheniformis, Lactobacillus sp. and Saccharomyces cerevisiae, can be used as feed additives in the feed formula of domestic laying hens. To support the production and quality of chicken eggs, Nutrient ConcentratesBLS can be used up to levels of 2% in the feed formula.

  A study was carried out at the Poultry Department, Faculty of Animal Husbandry, Padjadjaran University, Bandung Indonesia, in order to determine the effect of Noni (Morinda citrifolia L.) juice and Palm sugar (Arenga pinnata) supplementation in drinking water on the lipid profile of broiler chicken. One hundred (100) day old commercial broiler chicks were randomly allocated to four (4) treatment groups as T1, T2, T3 and T4 with 25 birds per treatment group replicated five times of five (5) birds per replicate in a Complete Randomized Design (CRD). The birds in the first group (T1) were given only 0.3% Noni in drinking water, while as other groups were supplemented with 0.3% Noni+2% Palm sugar (T1), 0.3% Noni+3% Palm sugar (T2) and 0.3% Noni+4% Palm sugar (T4). The blood samples were randomly collected from three (3) birds per replicate at the end of the study at 5th week and analyzed for the estimation of blood lipid profile viz. Total Cholesterol, Low Density Lipoprotein (LDL), High Density Lipoprotein (HDL) and Triglycerides. Results revealed that using combination of Noni and Palm sugar significantly (p<0.05) decreased the total Cholesterol, triglyceride and Low Density Lipoprotein (LDL) levels. A numerical decrease in the levels of total cholesterol and LDL was observed with increase in the level of Palm sugar among the treatment groups. Highest reductions were observed in the groups supplemented with 0.3% Noni+4% Palm sugar (T4). Although, High Density Lipoprotein (HDL) did not increase in the present study but the ratio between HDL and LDL increased numerically in the treatment groups with increase in the concentration of Palm sugar. Thus, in view of the results obtained, it could be concluded that both Noni and Palm sugar have beneficial health effects with regard to their ability in altering the lipid profile of broiler chicken.

  Background and Objective: Improving the quality of waste containing high levels of chitin through bioprocesses that utilize the services of the microbes Bacillus licheniformis, Lactobacillus sp. and Saccharomyces cereviseae can generate a high-quality product that can meet the requirements of domestic chickens. The objective of this study was to determine the optimal bioprocessing conditions to make a nutrient concentrate, as well as to describe its biological quality for the domestic chicken. Materials and Methods: This study utilized experimental methods in the laboratory that consisted of a completely randomized design with six treatment rations (R0, R1, R2, R3, R4 and RS) that were replicated five times. The data were subjected to analysis of variance and the differences between treatments were tested by Duncan's multiple range test. Results: Bioprocessing shrimp waste with Bacillus licheniformis for two days, followed by Lactobacillus sp. for two days and finally, Saccharomyces cereviseae for two days resulted in the best nutrient content (48.50% crude protein, 7.81% crude fat, 7.57% calcium and 3.14% phosphorus), The metabolizable energy value and protein digestibility of the nutrient concentrate for the domestic chicken were 2613.90 kcal kg1 and 72.91%, respectively. Conclusion: Processing shrimp waste for poultry feed, especially for domestic poultry, can be achieved through multilevel fermentation technology that uses microbial services to produce a nutrient concentrate with good chemical and biological qualities.
