| The objective of this experiment was evaluating the effects and adjustabilityof Ultra-fine Chinese herbal feedstuff additives(UFCH) on growth andintestines performance on early weaning piglets. The Ultra-fine Chinese herbaladditives(UFCH) were made of PeriIla Frutes, Radix codonpsispillosulae, Rhizoma atractylodis macrocephalae, and so on. Ninety -sixcrossbred early weaned piglets (Large Yorkshire X Landrace) of 21 days oldwere assigned into 4 groups (A, B, C, D)with 3 repetitions by weight and sex,every repletion had 8 piglets, then to carry on feeding trial. The four groupsdiets respectively were 0.05% antibiotics(include Colistin Sulfate SolublePowder and Maxus, 0.25% UFCH, 0.5% UFCH and 1.0% UFCH supplementation inthe basal diet. The trial results were as follow:Growth performance: Average daily gain(ADG) of group C wassignificantly (P＜0.05) higher than that of control group A, no significantelect(P＞0.05) was observed between group B, D,these three experiment groupsincreased respectively by-0.15%(P＞0.05), 21.65% (P＜0.05) and 11.96%(P＞0.05). Average daily teed intake(ADFD)of all groups had no significantlydifference(P＞0.05),but the ADFD of group C, D increased 16.92%(P＞0.05),6.1%(P＞0.05)respectively compared with control group A; feed to gain ratio(F/G) of all groups had no significantly difference(P＞0.05), while effects of thethree experiment groups were better than that of control group,the F/G of threeexperiment group decreased by 4.58%(P＞0.05), 5.34%(P＞0.05), 5.34%(P＞0.05)respectively when compared with the control of group A; Diarrhea frequency ofgroup B, C, D were significantly (P＜0.05) lower than control,and decreased by 84.50%(P＜0.05), 92.25%(P＜0.05),和69.38%(P＜0.05).Serum bio-chemical parameters: no significant effects existed in totalprotein(TP),albumin(ALB), globulin(GLO), urinary nitrogen(BUN),glutamicoxalocetic transaminase(AST) of serum in (P＞0.05);but UFCH can increasedGLU in Serum,the highest one among those groups was the group C;theconcentration of BUN could be decreased by 0.5% UFCH group C and theconcentration of cholesterol TC could be decreased by 1.0% UFCH groupD.ALT of group C was significantly(P＜0.05) higher than the control,nosignificant effect (P＞0.05) was observed between group B, C and control groupA.The concentration of AMY in group B, C, D increased by 17.15%, 6.55% and20.61% respectively, but no significant differences(P＞0.05). The highestconcentration of ALP was the group C, increased by 20.22%(P＞0.05),66.37(P＜0.05) and 44.80%(P＞0.05) respectively when compared with controland group B, D.The concentration of three- thyroid hormone(T3) in thoseexperiment groups were higher than that control of group A,increased by12%(P＞0.05), 34%(P＞0.05) and 16%(P＞0.05) respectively. The highestconcentration of four-thyroid hormone(FT4) was the group C, increased by18.75%(P＞0.05) and 34.43%(P＜0.05). 19.25(P＞0.05) respectively whencompared with control and group B, D.Status of intestines:pH of those three experiment groups in cecum andcolon were lower than control, pH of groups B, C in cecum was significantly(P＜0.05) lower than control,pH of three groups in colon was significantly(P＜0.05) lower than control; the concentration of Propanoic Acid in cecum andcolon of groups B, C, D were higher than control; Group C had higher(P＜0.05)n-Butyric acid and Propanoic Acid in cecum and n-Butyric acid in colon thancontrol,increased by 49.59%(P＜0.05), 55.75%(P＜0.05), 34.86%(P＜0.05)respectively;The colonic villu length of three experiment groups were longer than control,but the difference were not significant(P＞0.05);cecum and colonE.coli concentration of experiment groups were lower than control,but nosignificantly differece (P＞0.05);group C had the lowest E.coli number thanother groups,descreased by 13.30% when compared with control, cecum andcolon Lactoacilli number of experiment groups were higher (P＜0.05) thancontrol, cecum Lactoacilli number increased by 24.89%(P<0.05).30.19%(P＜0.05),26.80%(P＜0.05) respectively when compared with control,andcolon Lactoacilli number increased by 23.38%(P＜0.05), 30.14%(P＜0.05),25.11%(P＜0.05) respectively when compared with control.The density of ammonia in excrement:compared with group A,the densityof ammonia in excrement in three experiment groups decreased by11.21%(P＞0.05). 20.09%(P＜0.05), 13.55%(P＞0.05) respectively.The results suggested that feeding early weaning piglets with differ dosageUltra-fine Chinese Herbal feedstuff additive improved piglets growth andintestines performance,decreased the harm of intestines which because ofweaning hyperirritability,and decreased diarrhea frequcy.The best dosage ofUltra-fine Chinese Herbal feedstuff additive was 0.5%.
