Low weaning weight is one of the key limitations to obtainable post-weaning performance in nursery pig. Pig growth is related by many factors, including pathogen pressure, genetics, environment and nutrition. These factors have been associated with variation in pre-weaning piglet weight. Moreover, the small intestinal structure are an important mechanism of post-weaning diarrhea and growth performance. Low feed intake after weaning has influence on gut morphology and changes functional. The aim of this study was to study effects s of AMPs on growth performance and health status in nursery pig.
Materials and Methods :
Location: Heilongjiang (300 sow heads)
Trail period: 31 days
Animal: nursery pigs (age 30 days)
Dosage: Ampter 500 g/ton feed
Table 1. Effects of AMPs on growth performance of nursery pigs
|Population at start (H)||148||106|
|Avg. age (day)||30||30|
|Initial total weight (kg)||1214||839.9|
|Avg. initial weight (kg/H)||8.2||7.92|
|Population at end (H)||146||106|
|Total weight (kg)||2636.4||2388.71|
|Avg. final weight (kg/H)||20.28||22.53|

Mortality rate (%)
Control was died two pigs and seven pigs were sick from lame (2 pigs) and encephalitis disease (5 pigs).
Result: two groups had slightly diarrhea at day 4 of the exp. due to cold and wet weather and lack of insulation. AMPs group notably more avg. final weight, ADG and ADFI and it also presented low FCR. Control group was lost two pigs and seven pigs were sick from lame (2 pigs) and encephalitis disease (5 pigs).
Conclusion: AMPs speedy recover pig health after weaning and protect animal from pathogen bacteria and stimulate animal performance.
