Improve energy utilization in swine with FRA LeciMax

The addition of FRA LeciMax in swine rations counteracts the effects of a negative energy balance in lactating sows and gut immaturity in weaned piglets.

Efficient energy utilization lies at the base of producing healthy and strong piglets. Maintenance and production functions are directly dependent on energy availability and have a direct impact on the reproductive, litter and growth performance of swine. To obtain a high energy content, nutritionists add fat and oils to swine rations. However, feed intake is physically restricted in lactating sows which may result in a negative energy balance as their lower feed intake cannot meet their high energy requirements. Therefore, it is essential that the higher levels of fat are properly digested.

Fat digestion in weaned piglets is limited as their gut is not yet fully developed in terms of bile acids production and lipase activity which is necessary for normal fat digestion. To enhance fat digestion and energy utilization, it is essential to improve fat emulsification. This can be achieved by the addition of lysolecithins. These lysolecithins are biosurfactants and form the base of FRA LeciMax. Lysolecithins support fat emulsification and effectively improve nutrient digestibility & nutrient absorption, thereby enhancing energy utilization.

FRA LeciMax

FRA LeciMax increases the energy and nutrient availability in sows. This improves body condition scores and shortens the farrowing duration, resulting in improved fertility and an increase in live-born piglets. As not only fat but also protein becomes more available, milk quality and suckling piglet growth are improved. In weaned piglets, FRA LeciMax facilitates an improved growth performance and feed efficiency due to the improved nutrient digestibility and absorption.

Improved energy state of sows

Due to an insufficient feed intake and high nutritional requirements, lactating sows can develop a negative energy balance during which they catabolize their body reserves. This reduced body condition state directly influences the fertility, milk quality and performance of piglets. To demonstrate that FRA LeciMax can counteract the negative energy balance effects in lactating sows, the efficacy of FRA LeciMax was tested with a group of 42 sows. In the trial, 21 sows received FRA LeciMax on top of their diets.

FRA LeciMax improved sows’ feed utilization and thereby their energy state. Sows receiving FRA LeciMax had more energy available for farrowing due to a better fat emulsification and higher nutrient absorption. Consequently, the farrowing duration decreased which might have increased the number of live-born piglets as a longer farrowing process decreases piglet survival due to oxygen deprivation. Because of an improved energy state, less body reserves were catabolized to support the high energy requirements as reflected by a reduced reduction of backfat thickness and weight loss. Moreover, FRA LeciMax increased the availability of nutrients other than fat by raising enzymatic potential. This led to improved milk quality reflected by the increased dry matter and gross energy content which explained the increased growth of the suckling piglets. As the sows had a better body condition at the time of weaning, the number of open days was reduced. Therefore, the addition of FRA LeciMax effectively improved sow and suckling piglet performance.

Increased body weight and ADWG in piglets

In the period after weaning, weaned piglets have a reduced capacity of fat digestion due to lower levels of bile salts and pancreatic lipase production. This affects the growth performance of weaned piglets. To demonstrate that FRA LeciMax can counteract the effects of the weaned piglets’ immature gut, the effect of FRA LeciMax on piglet performance was further investigated. In another trial, FRA LeciMax was added to the diets of 297 weaned piglets. During this critical period after weaning, both body weight and average daily weight gain improved in the piglets receiving FRA LeciMax. This is explained by the fact that FRA LeciMax improved fat emulsification and nutrient absorption leading to a higher nutrient utilization and a better growth performance. Piglets with a higher body weight at the end of the weaning period will also perform better as fattening pigs, which is of economical interest. Moreover, FRA LeciMax reduced FCR as it improved nutrient utilization. Hence, FRA LeciMax can overcome the physiological limitations of the immature gut of piglets.

Conclusion

These trials show that FRA LeciMax counteracts the effects of a negative energy balance in lactating sows. FRA LeciMax improved sows’ feed utilization and thereby their energy state. The sows had more energy available for farrowing due to a better fat emulsification and higher nutrient absorption. In addition, FRA LeciMax has shown to counteract the effects of gut immaturity in weaned piglets as both body weight and average daily weight gain improved. It can therefore be concluded that adding FRA LeciMax in swine rations effectively improves the overall performance of sows and weaned piglets.
