乌蒙黄羽乌骨鸡蛋、肉营养分析研究

两次测定,乌蒙黄羽乌骨鸡肌肉脂肪、蛋白质、氨基酸的总量与乌蒙驻相近,蛋的胆固醇含量比乌蒙鸡低１０．９４％;肌肉中谷氨酸等５种含量较高的氨基酸占氨基酸总量的５０．４８％（第１次测定胸腿肌）或５２．３３％（第２次测定胸肌）。     

蛋白质营养研究新阶段

随着蛋白质营养理论研究的不断深入,蛋白质营养理论先后从粗蛋白体系发展到氨基酸营养和肽营养理论。氨基酸营养研究已被引起高度的学术重视,其营养理论逐渐被人们所了解和熟知。但是,有关小(寡)肽的营养代谢机理研究甚少,并且小(寡)肽具有的独特营养代谢作用是氨基酸无法取代的。由于单方面从氨基酸和肽代谢入手研究蛋白质营养,不能反映蛋白质代谢的整体模式,因此,本文以氨基酸参与的蛋白质代谢动力学模型为基础,阐述蛋白质营养与肽代谢之间的关系。     

Diet‐associated hepatic failure and immune‐mediated hemolytic anemia in a Weimaraner

Objective: To describe the medical and nutritional management of a 4‐year‐old Weimaraner with acute hepatic failure and immune‐mediated hemolytic anemia (IMHA) associated with consuming a commercial dog food. Case summary: A 4‐year‐old male castrated Weimaraner developed signs of IMHA, hepatic failure, disseminated intravascular coagulopathy, and malnutrition after consuming a commercial dog food. During the course of hospitalization, medical management included immunosuppressive therapy and supportive care. Nutritional support consisted of both enteral and parenteral nutrition. The dog was discharged after 19 days of hospitalization and fully recovered by 6 months. An investigation by the Food and Drug Administration was not able to determine the exact cause of the acute hepatic failure and IMHA. New information provided: This is the first case report documenting the medical and nutritional management of a critically ill animal associated with ingestion of this commercial dog food.

The relationship of feeding patterns and obesity in dogs

The rates of dog obesity are increasing and a greater understanding of feeding patterns is required to combat the problem. This study examined relationships between dietary patterns and caloric intake, and nutrient content of foods fed as it relates to obesity in dogs in the United States. Sixty‐one owners and their dogs were enrolled, and lifestyle surveys, food frequencies, and 3‐day food records were collected. Significant differences in overall kcal intake per kilogram of body weight were found (p < 0.04). Crude fibre in dog food was positively associated with protein and negatively associated with fat regardless of the dog’s weight (p < 0.001). Lean dogs received significantly more crude fibre in relation to overweight dogs regardless of the number of treats they received (p < 0.01), and their diets had greater micronutrient densities (p < 0.03) suggesting that high fibre influences body condition. Additionally, owners who ate nutrient‐rich, calorie‐poor diets had normal weight dogs, and owners that fed more table scraps had overweight dogs. Regardless of body condition, 59% of dogs received table scraps, which constituted 21% of daily caloric intake. The nutrient density of scraps fed was variable and did not meet National Research Council’s recommendations for micronutrient adequacy.     

谷氨酰胺小肽的吸收及其营养生理效应研究进展

谷氨酰胺(Gln)因其对人和动物的重要营养生理作用而引起广泛关注,而谷氨酰胺小肽是谷氨酰胺和其他氨基酸形成的小肽,其性质更加稳定,可能比谷氨酰胺具有更强的营养效应和应用潜力。本文总结了谷氨酰胺小肽的吸收及其营养生理效应的研究动态,提出了在仔猪生产中应用谷氨酰胺小肽添加剂的意义。
