Effects of Lysophospholipid Emulsifier Supplementation in the Diet of Sows

A total of 12 (Yorkshire×Landrace) sows (450 to 500 day old) with an average BW of 227.4±18.7 kg were used to evaluate the effect of 0.05% lysophospholipids on growth performance and nutrient digestibility of sows and piglets during the experimental period. Pigs were assigned to 3 treatment groups: 1) basal diet (CON), 2) CON+0.05% lysophospholipids after farrowing (TRT1) for 3 weeks, and 3) CON+0.05% lysophospholipids from 2 weeks before farrowing upto 3 weeks after farrowing (TRT2) i.e. for 5 weeks. Each treatment group comprised 4 sows. TRT1 and TRT2 groups showed no significant effects on growth performance of sows and piglets and nutrient digestibility of sows, as compared with CON (P>0.05). TRT1 group sows had decreased BW, after farrowing 1.2% and weanling 2.5%; increased BW loss, 7.8%; and increased litter, 3.4%. Likewise, TRT2 group sows had decreased BW, weanling 2.0%; increased BW loss, 27.8%; and increased litter, 14.9%, as compared with CON. Piglets on 0.05% lysophospholipids supplement had improved BW (TRT1, up to 12.4%; and TRT2, up to 18.0%) and an average daily gain (TRT1, up to 18.1%; and TRT2, up to 24.9%), as compared with CON, even though there were no significant effects. The overall results indicated that 0.05% lysophospholipids supplementation does not increase growth performance of sows but might be reflected as positive growth performance in piglets.

Effects of lipid sources, lysophospholipids and organic acids in maize-based broiler diets on nutrient balance, liver concentration of fat-soluble vitamins, jejunal microbiota and performance

Three experiments with a 2 × 2 × 2 factorial arrangement were conducted to evaluate maize-based diets for broilers containing different lipid sources [soybean oil (S) or beef tallow (T)] supplemented with or without lysophospholipids and organic acids on nutrient balance (Experiment I, evaluation period of 10–14 d), on liver concentration of fat-soluble vitamins, on jejunal microbiota (Experiment II, sampling at d 14) and on performance (Experiment III, accumulated periods of 1–14, 1–21 and 1–42 d).A total of 1344 male chicks were used. In each experiment, the birds were allotted in a completely randomised design with 8 replications. The lysophospholipids were mainly composed of lysolecithins and the organic acids blend was constituted by lactic (40%), acetic (7%) and butyric acids (1%).An interaction between lipid sources and lysophospholipids was observed on faecal apparent digestibility of lipid (ADL), which improved with lysophospholipids addition in T diets. Broilers fed on S had higher ADL and faecal apparent digestibility of nitrogen-corrected gross energy (ADGEN).It was not possible to demonstrate a significant treatment effect on the liver concentration of vitamins A and E, even with the differences in fatty acid profile between S and T.Enterobacteria values were below the detection threshold. Lysophospholipid supplementation reduced gram-positive cocci in T-fed birds. S diets promoted lower total anaerobe counts compared with T diets, independent of additives.S diets increased BW gain and feed:gain ratio in all evaluation periods. Lysophospholipids and organic acids improved feed:gain ratio at 1–21 d in T diets. Furthermore, main effects were observed for lysophospholipids and organic acids at 1–42 d, which increased BW gain and improved feed:gain ratio, respectively.No positive interactions between additives were found.

Effect of dietary supplementation of lysophospholipids on productive performance, nutrient digestibility and carcass quality traits of broiler chickens

An experiment was carried out to evaluate productive performance, nutrient digestibility and carcass quality traits of broiler chickens fed diets supplemented with an exogenous emulsifier based on lysophospholipids prepared by enzymatic conversion of soy lecithin. One thousand seven-hundred and fifty-five one-day-old male Ross 308 chicks were randomly divided into three experimental groups of nine replications each: control group (CON) fed a corn–soybean basal diet, and two groups fed CON diet supplemented with constant (1 kg/ton) or variable (1–1.5 kg/ton) level of emulsifier (CONST and VARI, respectively). At the end of the trial (42 d), birds receiving the emulsifier had a statistically significant (p < 0.05) lower feed conversion rate compared to the control. Body weight and daily weight gain were only slightly influenced by lysophospholipids supplementation, while mortality and feed intake resulted similar among the groups. No statistically significant effect of the emulsifier was observed on nutrient digestibility as well as slaughtering yields, skin pigmentation and incidence of foot pad dermatitis. The results obtained in this study suggest that the use of an emulsifier based on lysophospholipids improves feed efficiency while showed limited effect on carcass quality traits.
