Kuivatun kanansonnan energia-, valkuais- ja kivennäisarvo märehtijöillä

Abstract: Munivien kanojen kuivatun sonnan energia-, valkuais- ja kivennäisarvoa tutkittiin sulavuus- ja tasokokeella neljällä täysikasvuisella pässillä. Peruskokeessa rehuna oli ohra ja olki sekä tarpeelliset kivennäis- ja vitamiinitäydennykset. Toisessa kokeessa dieettiin sisältyi 13% kanansontaa, joka sisälsi typpeä 6.7 % k.a:sta. Energiansaanti vastasi ylläpitotarvetta. Raakaproteiinin ja monien kivennäisten saanti ylitti kanansontakokeessa normien mukaisen tarpeen. Kanansonnan orgaanisen aineen sulavuudeksi saatiin… Show more

“…The crude protein of DPM has been reported to be about 53 % digestible when fed as a main source of protein for sheep (Tinnimit et al 1972). However, other reports have assigned a higher protein digestibility of 73 -77 % (Lowman and Knight 1970, Bull and Reid 1971, Salo et al 1975. Smith and Calvert (1972) reported no difference in crude protein digestibility in diets where DPM was substituted for 0, 50 or 100 % of the soybean meal in sheep ration.…”

“…The gross energy of DPM varies from 12.5 to 14.6 MJ/kg DM (Lowman and Knight 1970, Bull and Reid 1971, Polin et al 1971, Tuller 1972, Vogt 1973). The digestible energy content is 8.4 MJ/kg DM for sheep and cattle making it approximately equivalent to low quality hay (Lowman and Knight 1970, Bull and Reid 1971, Salo et al 1975, Näsi 1976). Metabolizable energy (ME) values have ranged from 4.6 to 6.7 MJ/kg DM (Pryor and Connor 1964, Yoshida and Hoshii 1968, Oliphant 1974.…”
