Group differences in weaning weight was not significant,[link widoczny dla zalogowanych], 28 to 35 days of age,[link widoczny dla zalogowanych], significant differences between the average daily gain (P ; 0.05). In 28-42 days throughout the trial period,[link widoczny dla zalogowanych], average daily gain between the two significantly different (P <0.01). After weaning can be seen, especially within 1 week after weaning, the experimental group than the control group rapid weight gain. This may be SDPP in weanling diarrhea of piglets within 1 week after the best prevention, which showed better weight gain, so in practical application, must be emphasized that early weaning piglet diet 1 week after the nutritional preparation, appropriate in their diet to add SDPP, in order to promote the growth of piglets. Table 3 after weaning weight change *: significant difference (P <0.06 );**: significant difference (P <0.01), the same as the following table. 2.2 The effect of prevention of diarrhea can be seen from Table 4, the experimental group and control group rates of diarrhea, diarrhea frequency, diarrhea indices are significantly different (P <0.05). In this experiment, the degree of diarrhea with diarrhea rate, the frequency of diarrhea, diarrhea index said. Rate which reflects the incidence of diarrhea, diarrhea frequency, diarrhea index reflects the severity of diarrhea. Combination of the three indexes can be more fully reflect the piglets during the trial period of diarrhea. From the results, the degree of diarrhea in the experimental group was better than the control group, manifested as diarrhea rate, the frequency of diarrhea, diarrhea index decreased. * Table 4 level after weaning diarrhea and its mechanism sDPP 2.3SDPP the mechanism of roughly the following three aspects: First, spray-dried plasma protein powder is rich in protein, digestion rate, to meet the nutritional needs of pigs weaned, and rich in immunoglobulins (about 22%). Weaned piglets fed diets containing SDPP can improve the body's antibody levels piglets, to strengthen the immune purposes. Pierce et al (1995) ... studies have shown that plasma high molecular weight protein fed some get fed SDPP the same effect, indicating sDPP immunoglobulin in piglets in the promotion play an important role. Second, the spray-dried plasma protein powder palatability, and sensitization of small, almost the same as skim milk has a low sensitivity. Third, spray-dried plasma protein powder may contain some unknown growth factors can increase the growth of weaned piglets with diarrhea prevention J. 3 Conclusion The results showed that spray-dried porcine plasma protein powder (sDPP) for early weaned piglets after weaning diarrhea and daily gain significant feeding effect.
