Fermentation of Blood Meal with Bacillus amyloliquefaciens as Broiler Feeding

Objective: The aim of this study was to find out the best combination of bovine blood and agri-industrial waste which fermented by Bacillus amyloliquefaciens with different fermentation time to increase the quality of blood mixtures such as protein content, fiber content, nitrogen retention, amino acid compositionandenzyme activity. Methodology: Bovinebloodandagri-industrial wasteobtained from a slaughterhouse and traditional markets. The design used in this study was a Completely Randomized Design (CRD) factorial using three factors. Results: The results showed that there was a highly significant interaction (p<0.01) between blood concentrations, types of agricultural waste and fermentation time on crude protein, nitrogen retention and energy metabolism which the best results was mixtures blood (300/250 mL) and coconut pulp with fermentation time 120 h whereas, the crude protein content, nitrogen retention and enzyme activity (protease and mannanase) were 50.70 and 55.60%, protease 37.34 U gG1 and mannanase 0.992 U gG1, respectively. Meanwhile, the mixtures of blood (300/250 mL) and PKC had the best amino acid composition. Conclusion: The study can be concluded that the best results were mixture of blood meal (300 mL) with coconut pulp and fermentation time 120 h

Effects of Amino Acid Composition in a Bacillus amyloliquefaciens-fermented Mixture of Bovine Blood and Coconut Pulp on Growth Performance, Blood Cholesterol of Broilers

BackgroundandBackground: Bovine blood is a livestock by-product that can be used as a protein source for livestock, particularly when incorporatedin broiler rations. This studywas conductedtoinvestigatetheeffectsof aminoacids inBacillus amyloliquefaciens-fermented mixtures of bovine blood and coconut pulp (blood meal) on growth performance, blood cholesterol and erythrocyte content in broilers. Methodology: A total of 100 six day-old CP 707 (Strain Cobb) broilers were divided into 5 experimental groups with 4 replicates of 5 broilers. The experimental groups received rations supplemented with 0, 5, 10, 15 and 20% blood meal that substituted for fish meal or soybean meal. The experimental period was 5 weeks. Treatment effects on broiler performance parameters such as final body weight, final weight gain, average daily gain, feed intake, average abdominal fat and Feed Conversion Ratio (FCR), total serum cholesterol and erythrocyte count, as well as the return on investment were determined. Results: The group fed rations supplemented with 10% blood meal showed final body weight, final weight gain and FCR of 1,172, 1,035 and 1.75 g, respectively, which was significantly higher (p<0.05) than that for the other treatments. Rations with 10% blood meal also had the best return on investment ($0.92) relative to the other groups. Conclusion: A mixture of 10% bovine blood and coconut pulp fermented with Bacillus amyloliquefaciens can be used in broiler feed without adversely affecting broiler performance and can replace 47% of total fishmeal and 53% of soybean meal in broiler rations
