<\/span><\/p>\n La relation entre la consommation et la prise de poids des ko\u00efs est bien connue, les poissons mangent moins de nourriture et grandissent moins vite, mais tous les amateurs de poissons ne savent pas \u00e0 quel point le poisson grandit moins vite apr\u00e8s avoir mang\u00e9 moins de nourriture. Les poissons mangent de la nourriture, la dig\u00e8rent et l'absorbent en grande partie, et toute cette nourriture dig\u00e9r\u00e9e et absorb\u00e9e n'est pas utilis\u00e9e pour la prise de poids. Les poissons consomment des nutriments \u00e0 chaque instant pour maintenir leur vie et leurs activit\u00e9s ; ces consommations comprennent la consommation m\u00e9tabolique de base, c'est-\u00e0-dire pour maintenir la consommation m\u00e9tabolique de base de la vie ; la consommation m\u00e9tabolique de l'activit\u00e9, c'est-\u00e0-dire la nage normale du poisson, la recherche de nourriture, l'\u00e9vitement de l'ennemi, l'\u00e9vitement des dommages caus\u00e9s par la fuite, etc. la consommation de r\u00e9sistance aux environnements hostiles, etc. La plupart de ces d\u00e9penses se produisent m\u00eame lorsque les poissons ne se nourrissent pas.<\/span><\/p>\n\u3000\u3000Un test d'expert, avec l'alimentation en aquarium Nile tilapia pesant 3,2 ~ 3,4g, 5 groupes, temp\u00e9rature de l'eau d'environ 25 \u2103, \u00e0 travers l'air et l'eau microfluidique suppl\u00e9mentation en oxyg\u00e8ne, sati\u00e9t\u00e9 sans app\u00e2t r\u00e9siduel \u00e0 nourrir, la source de prot\u00e9ines de l'aliment pour la cas\u00e9ine ou l'albumine d'\u0153uf, source de sucre pour l'amidon alpha et dextrine, source de graisse pour l'huile de ma\u00efs, la densit\u00e9 \u00e9nerg\u00e9tique digestible 15,9 ~ 19J \/ kg, la digestibilit\u00e9 des prot\u00e9ines brutes 96 ~ 98%, dans l'alimentation de l'animal. Avec cet aliment de haute qualit\u00e9 et d'excellentes conditions d'alimentation, le tilapia du Nil n'utilise que 55-62 % des prot\u00e9ines pour sa croissance, et environ 40 % des prot\u00e9ines sont utilis\u00e9es pour le maintien de la vie et l'activit\u00e9.<\/span><\/p>\n\u3000\u3000Dans les \u00e9tangs ext\u00e9rieurs, la digestibilit\u00e9 des aliments n'est que d'environ 80 % dans des conditions normales d'alimentation avec des aliments de meilleure qualit\u00e9 et une consommation normale des poissons, et seulement 25 \u00e0 30 % des prot\u00e9ines des aliments sont utilis\u00e9es pour la croissance des poissons. En tenant compte des effets de divers facteurs, il est g\u00e9n\u00e9ralement vrai que 20 % des principaux nutriments contenus dans les aliments consomm\u00e9s par le poisson seront dig\u00e9r\u00e9s et excr\u00e9t\u00e9s dans les f\u00e8ces, que 30 % des prot\u00e9ines seront utilis\u00e9es pour la croissance et que 50 % des prot\u00e9ines, pratiquement tous les glucides absorb\u00e9s et la majeure partie ou une partie des graisses seront utilis\u00e9s pour le maintien de la vie et de l'activit\u00e9. C'est la situation alimentaire normale. Si le r\u00e9gime alimentaire du poisson est r\u00e9duit de moiti\u00e9, la prise de poids du poisson est-elle \u00e9galement r\u00e9duite de moiti\u00e9 ? Non. Il est essentiellement consomm\u00e9 pour sa survie et son activit\u00e9, sans prise de poids ou avec une l\u00e9g\u00e8re prise de poids, voire avec une perte de poids.<\/span><\/p>\n <\/span><\/p>\n <\/span><\/p>\n<\/p>","protected":false},"excerpt":{"rendered":"
