摘要

The digestive system of poultry breeders is highly solicited,especially late in the egg production period when the demand in lipids for yolk development increases.To maintain a good health status and optimal levels of egg production,the digestive system needs to be properly drained and stimulated.This study assesses the impact of the product DigestSea®containing a sulphated polysaccharide extracted from green seaweeds named MSP®LIPIDS,on liver physiology and laying performance of breeding turkeys in comparison with a choline and sorbitol complex.The trial was performed in two buildings,from 23 to 28 weeks of laying.One group of 2,016 turkey breeders received the choline and sorbitol complex at 1 L/1,000 L of drinking water while the test group of 2,110 turkey breeders received DigestSea®at a dosage of 0.5 L/1,000 L of drinking water,during 2 periods,first 10 days at 23 weeks of laying and again 5 days at 27 weeks of laying.Histological evaluation of the liver was performed at the end of the trial.The results show higher egg production in the DigestSea®group with a significant reduction of the biliary canal hyperplasia and blood capillaries leucocytosis in the portal area,associated with a statistically significant reduction of lipids overload in the liver.Overall,our results show that the use of DigestSea®containing MSP®LIPIDS helps maintain a high level of egg production and lower hepatic steatosis.In conclusion,the use of the product containing MSP®LIPIDS in breeding poultry production may be beneficial to maintain animal health and production levels.Further experiments are required to determine the mechanisms of action as a reduction of lipid resorption,metabolic changes,and an increased energy demand due to improving egg production.
