Tuna Red Meat as a Novel Ingredient in Pet Food for Dogs

ABSTRACT

Red meat from tuna canning factory was used to develop a pet food for dogs. Feed was developed by mixing cooked, dried, and powdered red meat with cereal flours in varying proportion. The combination that gave maximum hardness for the feed was selected as optimum. The developed feed had a crude protein content of 20.2 ± 0.95% and crude fat content of 4.70 ± 0.37%. Analysis of mineral content showed that it is rich in macro minerals, including phosphorus (2843.67 ± 206 ppm), sodium (1333.54 ± 56 ppm), and calcium (400.04 ± 21 ppm). Amino acid content of the feed showed that it meets the dietary requirements of dogs in terms of threonine, methionine, histidine, lysine, arginine, and tryptophan. Polyunsaturated fatty acid content of the feed was dominated by linoleic acid, followed by DHA and EPA.     

西北印度洋大眼金枪鱼渔场预报模型建立与模块开发

根据1990—2003年印度洋大眼金枪鱼延绳钓渔业数据和美国国家海洋和大气管理局提供的海表温度、叶绿素-a历史环境数据,应用环境因子叠加方法,构建了西印度洋大眼金枪鱼渔场预报模型,用于金枪鱼渔场预报。分析得出各月适宜海表温度、叶绿素-a浓度范围和历史高产区空间位置;导入实时海表温度、叶绿素-a等遥感栅格数据,分别提取适宜海表温度、适宜叶绿素-a浓度和历史高产区的空间栅格数据集,最后在空间上对3种栅格数据进行空间叠加并取交集。交集所指空间区域即为大眼金枪鱼潜在渔场位置。通过精度检验,表明该模型渔场预报精度为60.5%。并以VC++6.0工具为开发平台,对此模型进行了设计开发,实现了模块预报西北印度洋大眼金枪鱼渔场。
