The more you learn the better: Protein / 知多D: 蛋白質

As I discussed with different people (including vet), there seems to be a misconception of protein.  Here is a quick and non-technical overview on protein.  

跟很多狗友（包括獸醫）談論關於動物營養, 似乎很多狗友對蛋白質都有誤解.   這是一個短及容易明白的簡述.

Importance of Protein  All animals (people, dog and cats...) need protein in their diet.  For adult dog, protein is needed for everyday living as protein is lost in faeces, hair, skin, sweat and cell rebuilding.  Proteins are essential and have several important functions:  regulation of metabolism (as enzymes and some hormones)  a structural role in cell walls and muscle fibre repairing damaged tissue (wound healing) defense against diseases as protein is required in the formation of antibodies.  source of energy normal growth of hair, skin Excess protein is either converted to fat and used protein is eliminated from the body via the kidneys.	蛋白質的重要性 所有動物 (包抱人, 狗和貓) 都需要蛋白質.  對於成犬, 蛋白質是日常生失去, 例如從: 糞便, 毛髮, 皮膚, 汗腺 與細胞生長. 蛋白質是必要的而蛋白質有幾個重要的功能: 調節生層代謝（如酵素和某些激素） 負責細胞的結構及肌肉纖維的結構  修復受損組織（傷口癒合） 疾病的防禦需要蛋白質制做抗體 能量的來源 正常毛髮及皮膚生長 多餘的蛋白質會被轉化為脂肪及使用過的蛋白質會通過腎臟排出體外的
Quality of Protein for Canine  Per NRC recommendation, Protein per 1000 kcal is 56.3g (vs 21.3g of fat, 0 g of carbohydrate)  Animal proteins generally have a more balanced protein profile, with a greater proportion of essential protein and better digestibility, than plant proteins.  Digestibility in order (high to low) Egg Meat Fish Rice Other Grain	犬隻蛋白質 NRC建議, 每1000卡路里食物, 蛋白質的需要是 56.3 克（脂肪21.3克, 碳水化合物 0 克） 從動物來的蛋白質一般有比較平衡的蛋白質, 及比植物蛋白有更好的消化率. 消化率 (能被犬隻消化) (高至低) 雞蛋 肉類  魚  米  其他穀物
Protein Deficiency Lacking protein can cause serious health issues. Poor growth or weight loss Rough and dull hair coat Anorexia Increased susceptibility to disease Muscle wasting  Organ failure Pancreatitis	蛋白質不足 缺乏蛋白質會導致嚴重的健康問題。 發育差及消瘦  粗糙及失去光澤的毛  厭食症  增加對疾病的感性  肌肉萎縮 器官功能衰竭 胰狀炎
Home made Diet If you are making a balance home made diet for your dog, BRAVO!!! to you.   However, since left-over protein is removed from the body via the kidneys.  Dogs that are fed a high protein diet should have at least half-day to one day meat fasting per week depending on your dog size.  The fasting will help eliminate waste and also give your dog's kidneys a needed break.  Besides fasting, detoxification herbs can also help with cleaning the body and organs.	自製飲食 如果你正幫你的狗預的平衡飲食, BRAVO! 然而，由於遺留蛋白是通過腎臟排出體外. 餵食高蛋白飲食的狗應該有禁食肉的日子, 例如每星期一天至半天用你的狗的大小而定. 禁食肉有助於消除餘物及也給您的狗的腎臟休息時間. 除了禁食, 用排毒香草藥也可及幫助清洗身體 和器官.
