Supplementation of lysolecithin in combination with a multi-non-starch polysaccharides enzyme improves the feed efficiency during the post-weaning period in piglets

Abstract

The present study investigated the modification of feed formulations by replacing cereals with fat and supplementation with lysolecithin and/or multi-non-starch polysaccharides (NSPs) enzyme upon performance. The study implemented 480 weaned piglets starting at 8.1 kg and finishing at 27.6 kg. Piglets were assigned to four treatments (control, control supplemented with fat at 7.0 g/kg, control supplemented with lysolecithin at 0.5 g/kg, with lysolecithin and a multi-NSP enzyme at 0.5 g/kg each). The study was divided in first phase 1-15 days and second phase 16-40 days. Feed conversion was significantly improved in the group supplemented with lysolecithin and multi-enzyme compared to control during the second phase of the experiment (P < 0.05), while the rest performance parameters did not differ significantly between treatments.

Desempenho de frangos de corte alimentados com dietas com redução energética contendo diferentes tipos de emulsificantes

“…O maior consumo e pior conversão alimentar dos frangos alimentados com dietas suplementadas com o emulsificante A foi observado somente no período de 1 a 7 dias de idade, não ocorrendo nas demais fases analisadas. Este resultado contraria os encontrados por Papadopoulos et al (2014), que afirmam que dietas convencionais com adição de emulsificantes melhoram a conversão alimentar. Cho et al (2012), trabalhando com redução energética em dietas para frangos de corte, também observaram que a inclusão de emulsificantes exógenos melhorou o ganho de peso médio dos animais.…”

Effect of supplementation of lecithin and carnitine on growth performance and nutrient digestibility in pigs fed high-fat diet

“…No significant difference on average daily gain was reported by Papadopoulos et al . [ 40 ] by supplementing 0.5 g/kg lysolecithin along with 7 g/kg fat in the diet of weaned piglets.…”

Effects of Dietary Lysolecithin Supplementation during Late Gestation and Lactation on Sow Reproductive Performance, Sow Blood Metabolic Parameters and Piglet Performance

“…Despite their high energy density, however, animal fats can be highly variable in their composition and quality [ 7 ] and are associated with comparatively incomplete absorption, since they mainly contain saturated, long-chain fatty acids (FAs). These saturated long-chain fatty acids (LCFAs) are known to be less readily incorporated in the micelles of the intestinal lumen [ 8 , 9 ], a prerequisite for exposure to the activity of pancreatic lipases [ 10 , 11 ].…”

“…Addition of digestive enzymes and emulsifiers within the feed of both sows and fattening pigs has also been used to aid in digestion, absorption, and retention of fat and other nutrients [ 9 , 12 ]. Lysolecithin (LL) is one of the most studied emulsifying agents added to improve digestibility [ 13 ].…”
