Trial#51b: Effects of Turval 16 Swine in the diet of the weaned piglet on: value of intestinal pH, concentration of total E. Coli in the feces and intestines.
....it can be deducted that the use of Turval B0399 in the diet of the piglet weaned precociously can contribute in controlling the presence of a part of the noxious micro organisms present in the gastrointestinal system (total coli), and controlling the acidity contents.
Prof. Paolo Bosi ( DIPROVAL –University of Bologna)
Summary
The test was conducted at the Experimental Zootechnical Structure of the DIPROVAL – University of Bologna, on 24 weaned piglets 19 days old, taken from 6 litters and divided in half by sex.
A dosage of Turval 16 Swine (1,8 g/kg of fodder) was made in conditions of challenge, inducing in the animals a slightly altered state after a single oral administration of E.Coli K88 (1010 CFU per head).
All the subjects were slaughtered at the end of the test.
The results show that the additive preparation Turval 16 Swine:
- the gastric and intestinal pH was significantly lower at the ileum and cecum level;
- the number of total coliforms found in the feces was inferior to the average.
Materials and Methodology
The test was conducted at the Experimental Zootechnical Structure of the DIPROVAL – University of Bologna, on 24 weaned piglets 19 days old, taken from 6 litters and divided in half by sex.
All the subjects were slaughtered at the end of the test.
Concentration of Turval 16 Swine in the feed for testing: dosage 1,8 g/kg of feed = 7.5 x 10 3 CFU Kluyveromices B0399/g of feed
Identification of testing feeds :
· Control = feed without additive
· Turval 16 Swine (80 % Turval B0399 + 20% fine bran of wheat) = feed with 1,8 g/kg of additive (recommended dosage)
· (Bifidusbacterium = feed with Bifidobacterium suis).
Results and discussion
Effects on the pH of the intestine
The effect of the addition of Turval B0399 in the piglets’ diet on the pH in the different parts of the digestive system are presented in chart 2
The gastric and duodenal pH was not significantly modified by the addition of TurvalB0399 compared to the control group, while in the ileum and in the cecum, it was significantly lower.
Concentration of total E.Coli in the faeces
In chart 2 , the effect of the addition of Turval B0399 in the diet on the presence of total E.Coli in the feces on the 8th day after administration of E.Coli K88 can be observed.
As can be seen the number of total coli found in the feces was inferior with the use of Turval B0399 compared to the average of the other two treatments.
Final Considerations.
On the basis of the results available up until now and from the examination on the whole of the two tests 51A and 51B, it can be deducted that the use of Turval B0399 in the diet of the piglet weaned precociously can contribute in controlling the presence of a part of the noxious micro organisms present in the gastrointestinal system (total coli), and controlling the acidity contents.
This contributes, in average breeding conditions, in producing a major growth , when the additive is utilized at recommended dosages.
