METABOLISM AND NUTRITION

Feeding co-extruded flaxseed to pigs: Effects of duration and feeding level on growth performance and backfat fatty acid composition of grower-finisher pigs.

M. Juarez, M.E.R. Dugan, N. Aldai, J.L. Aalhus, J.F. Patience, R.T. Zijlstra, and A.D. Beaulieu

Purpose :

To examine the effect of co-extrusion on subsequent Omega-3 fatty acids in pig tissues.

Methodology :

80 pigs were included in the study with 4 gilts and 4 barrows per treatment. Animals were grouped by weight, parentage and gender.
Nine treatment groups and one control group were included in the study. The nine treatments were 3 levels of LinPRO (10, 20, 30%) tested for each of 3 different durations (4, 8, and 12 weeks).
Pig weights and feed consumption were used to calculate average daily gain, average daily feed intake and feed conversion.
Analysis included level of flaxseed in the diet, length of feeding, gender, and interactions between all effects.

Results :

Feeding flax containing diets for increasing durations led to increases in Omega 3 and Omega 6 fatty acids, total polyunsaturated fatty acids and a reduction in total monounsaturated fatty acids and saturated fatty acids.
Barrows had higher interactions for ADG, ADFI and lower feed conversion than gilts. As dietary flaxseed increased, ADFI decreased but ADG was unaffected.
Prolonged feeding of co-extruded flaxseed, independent of its level of dietary inclusion, reduced ADG.

Conclusion :

Addition of LinPRO to pig diets provided a highly available source of Omega-3, which resulted in increased Omega-3 levels in backfat.
It is possible to achieve the levels of Omega-3 required for an enrichment claim by varying the level and duration of co-extruded flax fed to pigs.

The Effect of Enzyme Supplementation on Egg Production Parameters and Omega-3 Fatty Acid Deposition in Laying Hens Fed Flaxseed and Canola Seed

Purpose :

To evaluate the effect of feeding LinPRO to laying hens to produce eggs that contain a significant level of Omega-3 fatty acids for the commercial egg market.

Methodology :

648 laying hens under semi controlled conditions were randomly assigned six test diets, administered through the production peak (39 to 63 weeks of age)
Birds were weighed individually at the start and end of the experiment
Egg production was recorded daily, and eggs were weighed in the middle of each period
Using a wide number of scientific methods, the following were tested :
Egg production
Hen Weight and Eggshell quality
Digesta Viscosity and Total Tract Fat and NSP Digestibilities
Egg Fatty Acid Profile

Results :

Feeding LinPRO at an inclusion rate of 15% in the commercial laying hen diet resulted in an Omega-3 fatty acid content of >350mg per 52g egg.

Conclusion :

High levels of dietary flax adversely affected hen production performance. Inclusion of LinPRO in laying hen diets diminished these effects and, as well, increased the Omega-3 content of eggs to a level greater than the 300mg/52g egg required by CFIA labelling guidelines.

Modern day consumers have become increasingly aware of the quality and nutritional value of their diets with a particular focus on Omega-3 essential fatty acids. One common strategy for increasing Omega-3 dietary intake of humans is through the consumption of functional foods such as Omega-3 eggs.

Since the fatty acid composition of the egg yolk is largely related to the fatty acid composition of the animal’s diet, enrichment of eggs can be achieved naturally through the addition of ingredients such as linPRO.

O&T Farms Ltd. has been actively involved in the egg industry for generations. Through extensive research and product development they have designed a patented dry extrusion process to maximize the benefits of Omega-3s in flaxseed and improve the transfer of these fatty acids into the eggs of laying hens. The company closely with producers and consumers to ensure eggs produced using linPRO meet the highest standards of quality.

Effects of LinPRO on Production and Fatty Acid Profile of Eggs

Research Abstract

METABOLISM AND NUTRITION

Authors :

Henry L. Classen (University of Saskatchewan)

Purpose :

Digestibility Trial: To determine the apparent metabolizable energy (AME), and amino acid and fat digestibility of LinPRO when fed to broiler chickens.
Broiler Trial: To study the use of graded levels of LinPRO on the performance of broiler chickens and to study the impact of diet on the fatty acid profile of broiler chicken carcasses.

Methodology :

Digestibility Trial:

Extruded LinPRO at 30% of a basal diet was compared to an equal amount of flaxseed and peas that were ground in a hammer mill before use.
Chicks were fed a commercial diet from 1 to 24 days of age and then transferred to a treatment diet containing 0 or 30% of the test meal.
After 7 days, the contents of the proximal ileum, terminal ileum and feces were collected for analysis.

Broiler Trial:

Four dietary treatments were used (0, 5, 10 or 15% LinPRO), with each formulation containing equal protein and energy.
Each treatment was replicated five times with 124 birds per replication.
Birds were on trial from 0 to 39 days of age.
Body weight, feed consumption, daily mortality and a subjective litter quality assessment were recorded throughout the trial.
At 19 and 39 days of age, ileal contents and fatty acid profiles of carcasses were examined.

Results :

Digestibility Trial:

Birds fed extruded LinPRO gained more weight and converted feed more efficiently than those that were fed the same ingredients in a non-extruded form.
Diets including LinPRO had a lower AME, as well as reduced fat digestibility in comparison to the non-extruded form. However, all amino acids except methionine and serine were more digestible for LinPRO.

Broiler Trial:

LinPRO resulted in a linear decrease in growth rate for 0-19 days, but had no effect on gain from 19 to 39 days. The degree of this effect was relatively small.
LinPRO did not affect the total fat content of the carcass; however, including LinPRO had a major effect on the fatty acid composition of the carcass fat. Most notably, omega-3 fatty acids increased while palmitic and oleic acid decreased.

Conclusion :

LinPRO caused a major increase in the omega-3 content of carcass fat with the largest portion of this increase coming from linolenic acid.
Extrusion does improve nutrient utilization.
