In den letzten Jahren f\u00fchrten Fortschritte in Genetik, Ern\u00e4hrung und Management zu einer gro\u00dfen Produktivit\u00e4tsverbesserung. Dar\u00fcber hinaus haben die EU-Richtlinie von 1999 und die Verbrauchernachfrage die Produktion auf k\u00e4figfreie Systeme hin ver\u00e4ndert, bei denen das Hauptmerkmal darin besteht, dass H\u00fchner jetzt ihr nat\u00fcrliches Verhalten ausdr\u00fccken k\u00f6nnen.<\/p>\r\n

\r\n

Die Kombination von allem erfordert \u00c4nderungen, die darauf abzielen, dieses Verhalten besser zu verstehen (Bild 1 und 2).<\/p>\r\n<\/blockquote>\r\n<\/div>\r\n<\/div>\r\n

Wenn man das Verhalten von Wildv\u00f6geln beobachtet, verbringen sie die meiste Zeit mit dem Ausf\u00fchren von Verhaltensweisen wie Fressen und Futtersuche (Dawkins, 1989)<\/em>.
\r\nDie Vorfahren der V\u00f6gel waren Allesfresser und fra\u00dfen alle m\u00f6glichen Dinge wie Samen, Insekten, Kr\u00e4uter, unl\u00f6sliche Fasern usw (Klasing, 2005)<\/em>.<\/div>\r\n<\/div>\r\n

Vermahlen<\/h2>\r\n<\/div>\r\n
\r\n
\"\"<\/div>In Bezug auf die Verdauungsphysiologie ist der Muskelmagen das Schl\u00fcsselorgan.
\r\nHauptfunktionen sind:\r\n\r\n
    \r\n\t
  • Partikelgr\u00f6\u00dfenreduzierung<\/li>\r\n\t
  • Chemischer Abbau von N\u00e4hrstoffen<\/li>\r\n\t
  • Regulierung der Darmpassage<\/li>\r\n<\/ul>\r\n

    Wenn man bedenkt, dass die meisten Partikel, die zum Zw\u00f6lffingerdarm gelangen, einen Durchmesser von etwa 60 bis 40\u00b5m um haben<\/strong>, m\u00fcssen alle Stoffe m\u00f6glicherweise etwas gemahlen werden, weshalb V\u00f6gel in der Natur auch Sand (unl\u00f6sliche Steine) konsumierten<\/strong> auch Sand (unl\u00f6sliche Steine) konsumierten (Gionfriddo, 1994)<\/em>.<\/p>\r\n

    \r\n

    Um eine maximale Leistung zu erzielen, sollte die H\u00fchnerdi\u00e4t, \u201cnat\u00fcrliche\u201d Bedingungen imitieren, weshalb es ratsam ist, ihnen ein homogenes Mehlfutter zu geben, da H\u00fchner hiermit nicht nur das nat\u00fcrliche F\u00fctterungsverhalten ausdr\u00fccken k\u00f6nnen, sondern auch die Darmgesundheit gef\u00f6rdert wird.<\/p>\r\n<\/blockquote>\r\n<\/div>\r\n

    \"\"<\/div>\r\n
    \r\n

    Das Vorhandensein von groben Partikeln im Futter f\u00f6rdert die Mahlaktivit\u00e4t. Um diesen Prozess effizienter zu gestalten, sollten einige Steine, K\u00f6rner und Sand den Abbau von Futtermitteln unterst\u00fctzen (Svihus, 2011)<\/em>.
    \r\nWenn etwas unl\u00f6sliche Partikel im Futter vorhanden sind, verbessert sich auch die F\u00e4higkeit der Henne, Di\u00e4ten mit einem h\u00f6heren Ballaststoffgehalt zu verdauen.<\/p>\r\n

    \r\n

    Als Teil unserer F\u00fctterungsstrategie kann die Bereitstellung von etwas groben Partikeln f\u00fcr H\u00fchner zur Unterst\u00fctzung der Darmgesundheit beitragen. Dies hilft ihnen nicht nur, die Partikelgr\u00f6\u00dfe zu reduzieren, sondern f\u00f6rdert, wenn sie in die Einstreu gegeben werden, auch das Futteraufnahmeverhalten.<\/strong><\/p>\r\n<\/blockquote>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n

    Grit-Definition<\/h2>\r\n

    Bei der Betrachtung der Grit-Definition handelt es sich um kleine unl\u00f6sliche Stein- oder Sandpartikel. Unl\u00f6sliche Gritpartikel sollten jedoch nicht mit Kalkstein- oder Austernschalen verwechselt werden (Bild 3 und 4. Kalksteinschalen und Austernschalen beziehungsweise). Letzteres ist als Kalzium- und Mineralquelle im Futter enthalten.<\/p>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n

    Unl\u00f6sliche Gritpartikel (Granit) bleiben im Muskelmagen zur\u00fcck und f\u00f6rdern die Mahlaktivit\u00e4t. Einige Beispiele sind unten gezeigt.<\/div>\r\n<\/div>\r\n<\/div>\r\n<\/div>\r\n

    Grit empfohlene Einsatzmengen<\/h2>\r\n

    Die Verabreichung von Grit im H\u00fchnerfutter in alternativen Haltungsformen – schon in der Aufzucht – kann das Wohlergehen der Tiere erh\u00f6hen, da sie die M\u00f6glichkeit haben, das zu bekommen, was normalerweise in der Natur vorhanden ist. Die empfohlenen Mengen sind unten aufgef\u00fchrt.<\/p>\r\n<\/div>\r\n
