Study On Formulas Technical Parameter And Feeding Effect Of Molasses Multinutrient Block

Three experiments were conducted to investigate the effect of producing pressure and the time of pressure keeping on technical parameter of molasses multinutrition block(MMB) and observe lapping quantity of different rigidity of MMB and the effect of component(molasses,wheat bran,cement,Na-soil,urea and salt) and roasting technology on technical parameter of MMB.After this work,three different MMB were choosed for studying the influence of supplementation of the MMB on growth performance of boer-meliorated goats.Finally,the effect of supplementation of the MMB on nutrient intake and digestibility in goats were studied.The results were as follows:(1)Rigidity of block were been significant increased with growth of pressure(12.5kg/cm2,25kg/cm2,50kg/cm2 and 100kg/cm2),but there was no significant difference in rigidity of blockwhen be produced with 50 kg/cm2and 100 kg/cm2 of pressure(P<0.05).The time of pressure maintaining(0s,15s,30s,60s) had no significant influence on rigidity of block(P>0.05).The lapped quantity of different rigidity of MMB had significant difference with milk goat (P<0.05).The rigidity of MMB containing 5 percentage and 7 percentage of cement was significantly higher than 3 percentage(P<0.05).With increasing of content of molasses,the rigidity of MMB were significantly enhanced(P<0.05) ,but the diameter ,molding thickness and expanded thickness of MMB were significantly reduced(P<0.05).The results of wheat bran were contrary with molasses. With increasing of content of urea and salt, the moisture regain rate of MMB were significantly increased. It was advised that pressure of producing was 50kg/cm2, the time of pressure maintainingthe content of cement, Na-soil, molasses, bran, in MMB were 5%,8%,15~20% and 15~20%, respectively;the most content of urea and salt in MMB were 15% and 10%,respectively;the molding MMB were toasted for 68h under the temperature of 65℃after being solidified for 48h。(2)Forty-eight boer ewe goats (about 18kg of body weight)were used to determine the effect of different MMB on growth performance of goats. These Goats were divided randomly into four equal groups of 12 goats in each group .Goats in control were forage ad libitum with a concentrate mixture.Besides basic feeds,goats in groupⅠ,ⅡandⅢhad...
