貓咪的生活中充斥著各種病原，免疫力失調可能會使貓咪對於病原的抵抗力減弱，進而導致疾病的發生。當貓咪攝取不均衡或不足的營養時，可能影響免疫細胞的生成和活化，進而導致部分免疫機能的喪失。
根據統計數據顯示，5歲齡以上的貓咪罹患癌症的風險較高5。隨著貓咪漸漸走向高齡化，於2014年，腫瘤已超越慢性腎臟病成為台灣家貓十大死因之首21。多種因素，如基因變異、營養、肥胖3、年齡、壓力、環境致癌物、創傷和病毒…等，都可能是造成貓咪罹患癌症的原因。攝取優質的營養和維持適當的體態，即為貓咪日常生活中維持免疫力和健康的重要因素之一。
成貓為年齡介於1-7歲的貓咪。提供成貓熱量充足和營養均衡的飲食，乃成貓營養的關鍵5。
期許能藉由日常飲食使成貓保持最佳的身體狀態，並透過良好的免疫力來防範疾病。獸研所成貓免疫保養主食罐，旨在提供成貓支持免疫功能的營養，於是添加了以下的功能性添加物：
1. 微分子褐藻醣膠
海藻類植物，例如褐藻，富含褐藻醣膠(fucoidan)。褐藻醣膠是一種多醣體，文獻指出，具有維持免疫系統功能和抗氧化能力的潛力7, 9, 15, 19。
2. 酵素固態發酵培養的牛樟芝萃取粉末
研究顯示，牛樟芝(Taiwanofunguscamphoratus)所含的β-葡聚糖(β-glucan)18，具有抗癌10、抗氧化和維持免疫力6, 14的作用，也可保護肝臟機能12, 13, 20。
3. 富含ω3脂肪酸的魚油
魚油為EPA和DHA的主要來源，而EPA和DHA屬於ω3脂肪酸11。研究指出，ω3脂肪酸有助於維持免疫力和抗氧化，雖然魚油在貓的疾病應用研究上仍在發展中，但有些研究顯示ω3脂肪酸對腎臟病、骨關節炎、皮膚疾病和癌症是有所幫助的2, 4, 5, 9, 16。
獸研所的成貓免疫保養主食罐，除了依據美國飼料品管協會(Association of American FeedControl Officials, AAFCO)，美國國家科學研究委員會(National Research Council, NRC)和歐洲寵物食品產業聯盟(European Pet Food IndustryFederation, FEDIAF)的成貓每日基本營養需求建議量1, 8, 17進行配方之外，獸研所以優質的動物性蛋白來源，包含雞胸肉、鮭魚和鮪魚等，並佐以雞油，以提供成貓蛋白質和脂質的營養基礎，並加入維生素、礦物質和必需胺基酸，並加入洋車前子膳食纖維，以維護腸道健康。除此之外，更添加「褐藻、牛樟芝、魚油」，並搭配天然抗氧化劑維生素E以維持免疫力2, 9，從成貓期開始吃的營養，期許能讓他們健康的走到熟齡貓期。
除了營養均衡外，適量的飲食攝取也很重要！能量攝取不足在成貓可能造成體重減輕和肌肉消瘦的問題；反之，能量攝取過剩則會造成肥胖的問題2, 5。肥胖是造成癌症及其他成貓慢性疾病的風險因子之一3，因此，飲食量的控制和運動量的調整，有助於維持體態，對守護貓咪的健康很重要！
