Povzetek

Kunci se skotijo goli, slepi in nemočni. Zaradi zelo koncentriranega mleka dobijo mladi kunci veliko energije. Na splošno je mleko bogato z beljakovinami in maščobami, ima pa nizko vrednost laktoze. Do starosti 14 dni zauživajo samo materino mleko. Po 20 dnevu pa se počasi začnejo navajati na novo krmo. Odstavljamo jih od 32. – 35. dneva starosti. Jutranje sesanje se spremeni v več manjših obrokov, ki so razporejeni preko celega dneva. Tip in količina krme, ki jo kunci zauživajo do odstavitve, vpliva na vzpostavitev mikroorganizmov v slepem črevesu in fermentacijskih parametrov pri odstavitvi. Kakovost prehranskih beljakovin je pomembna za hitro rastne kunce, ki še nimajo dobro razvite fermentacije v slepem črevesu. Priporoča se 16 % surovih beljakovin v obroku. Za zadovoljevanje potreb po posameznih aminokislinah, je včasih najbolje dodajati kar aminokisline. V prehrani najpogosteje primanjkuje arginina, lizina ter metionina in cistein. Raziskano je, da kunci pred 35. dnem starosti še nimajo dovolj razvitega prebavnega trakta za prebavo škroba. V krmnih obrokih za kunce je zelo malo maščob, običajno pod 3 %. Vlaknina pa je zelo pomembna v prehrani kuncev. Ena izmed njenih glavnih vlog je omogočanje normalne prebave oz. razmer v prebavilih in s tem preprečevanje prebavnih bolezni, ker večinoma temeljijo na nadzoru črevesne mikrobiote. Vlaknina je hrana za nekatere mikroorganizme in se tako tudi razgrajuje. Običajni viri vlaknine so lucerna, slama in pšenični otrobi. Potreba po vlaknini je še posebej izražena v obdobju po odstavitvi. Nizek vnos vlaknine zavira prirast v 14 dneh po odstavitvi. Prav tako pa so pomanjkanje vlaknine povezali z manjšim zauživanjem krme in prebavnimi motnjami. Poskusi kažejo ugoden učinek prehranske vlaknine na odpornost proti patogenom.

Sekundarni naslov:	Rabbit nutrition at weaning
Sekundarni povzetek:	Rabbits are born naked, blind and helpless. The very concentrated milk gives young rabbits a lot of energy. Generally, the milk is high in protein and fat, but has a low lactose content. Until they are 14 days old, they consume only mother's milk. After 20 days, they slowly start to get used to the new feed. Weaning occurs around the 32nd - 35th day of life. Morning sucking transitions into several smaller meals spread throughout the day. The type and quantity of feed rabbits eat up to weaning affects the establishment of caecal flora and fermentation parameters during weaning. The quality of dietary protein is important for fast-growing rabbits because fermentation is not yet well developed in them. The recommended value for crude protein in the meal is 16%. It is best to add amino acids to meet their protein needs. The most important amino acids are arginine, lysine, and sulfur-containing amino acids such as methionine and cystine. It has been studied that rabbits cannot digest starch before 35 days of age. The fat content in rabbit diet is very low, usually less than 3%. However, dietary fiber is very important in rabbit nutrition. One of their main roles is the prevention of digestive diseases, as they control the intestinal microbiota. There they serve as food for some microorganisms and are thus decomposed. Common sources of dietary fiber include alfalfa, straw, and wheat bran. The need for fiber is especially noticeable in the post-weaning period. Low fiber intake will inhibit growth within 14 days of weaning. A lack of fiber is also associated with lower feed intake and digestive disorders. Experiments show a positive effect of dietary fiber on resistance to pathogens.
