Oil and fat sources of plant or animal origin are routinely included in diets fed to chickens; however, it is evident that the bird’s capacity to digest and absorb dietary fats is limited. The efficient utilization of dietary fat requires digestion and absorption of fat in the gastrointestinal tract. LYSOFORTE™ Dry acts as powerful bio-emulsifier and can improve the fat digestibility of chicken.
Key properties of LYSOFORTE™ Dry are as follows:
LYSOFORTE™ Dry may also alter mucosal barrier function and increase the gut permeability to macro-nutrients such as amino acids. In laying hens, egg yolk is made up of 32% fat, which is derived from the feed on a daily basis. Supplementation of LYSOFORTE™ Dry in commercial layer diets is beneficial for boosting fat digestion and improves the egg size and egg mass.
LYSOFORTE™ Dry are widely used in animal diets to increase the digestion and absorption of oils and fats and to improve animal performance and feed efficiency.
LYSOFORTE™ Dry is effective in improving the absorption of oils and fats in laying hens diets and achieves better egg weight, egg mass, and feed efficiency.
Linoleic acid is required for the synthesis of the lipoproteins that can be transported to the ovary for uptake by the developing ova in laying hens. Egg size cannot be maximized if the amount of linoleic acid available is not adequate to support the maximum rate of synthesis by the lipoproteins. LYSOFORTE™ Dry can promote better absorption of linoleic acid and facilitate to maximize the lipoprotein synthesis.
Live cells were treated with radioactive (C-14) linoleic acid, and at the same time, the cells were treated with LYSOFORTE™ Dry and standard soy lecithin. The cultures were left for one hour and the media removed. After processing the cell, suspensions were analyzed for radioactivity.
Results show that there was a more significant uptake of linoleic acid by the cell cultures in the presence of LYSOFORTE™ Dry than in the presence of soy lecithin. This indicates the ability of LYSOFORTE™ Dry to promote absorption of fatty acids. Results were expressed as DPM (disintegrations per minute) per 1000 live cells.

Laying hens were housed in battery cages under conventional conditions for lighting, heating, and ventilation. They are 35 weeks old and have reached their peak egg-production. By day 14 day, the laying hens have adapted to the balance cages.
At day 14, the laying hens are fed their respective experimental diets for 7 days to adapt to their digestion metabolism. During the main period (21-25 days) the birds are fed at a nearly ad libitum level, while water is freely available. The results showed that LYSOFORTE™ Dry supplementation resulted in an AME increase of 47kcal/kg.

A commercial trial was conducted in an attempt to improve egg weight and egg mass by supplementing LYSOFORTE™ Dry. The trial was conducted on laying hens aged 28 to 33 weeks. All birds were reared identically and are the same breed, house and fed under same conditions.
* A flock of birds producing at 93% with an average egg weight of 63g will have a daily egg mass output of 58.6 g/bird. Alternatively, you can calculate the total egg mass output over a whole cycle

A commercial trial was conducted with 64,000 Lohmann Brown laying hens from 20 to 35 weeks of age. The birds were fed with commercial mash feed which contained 24% wheat, 13% maize, 13% soybean meal, 10% peas, 8% triticale, 7% sunflower meal 6% meat and bone, 4.5% vegetable oil, and barley germs.
The summary of the results is as follows.

Fats and oils are probably the most problematic of all the ingredients used in poultry feeds. Their fatty acid profile, the level of free fatty acids and degree of hydrogenation can all influence digestibility and subsequent ME values. Efficient absorption of linoleic acid is required for the synthesis of the lipoproteins that can be transported to the ovary for uptake by the developing ova in laying hens. Egg size cannot be maximized if the amount of linoleic acid available is not adequate to support the maximum rate of synthesis by the lipoproteins.
LYSOFORTE™ Dry can promote better absorption of linoleic acid and facilitate to maximize the lipoprotein synthesis. Results from many research and commercial studies indicate that LYSOFORTE™ Dry supplementation would be beneficial for commercial laying hen to improve egg weight, egg mass, and feed efficiency.
