Poultry has gone through an exhaustive genetic development since we started domestication which also has made the animals more sensitive and demanding. Good egg quality needs a lot of attention that is why we have developed Ovostrong. A combination of synergic compounds to cover all aspects through one product.

In today’s nutrition, phytase has a very important role. Phosphorus from plants which is stored as phytic acid is indigestible to livestock. This anti-nutritional fraction, as well traps important factors such as proteins (amino acids), and minerals (Calcium, Phosphorus, etc.), and reduce the digestibility of feed which is energy consuming for livestock. Beside energy saving benefit, of adding phytase to feed; the amount of environmentally relevant emissions such as nitrogen (ammonia) and phosphorous would decrease, contributing to sustainability.

Short chain fatty acids in form of organic acids, have positive effect on intestinal mucosa health, overall production, and feed digestibility. Coated butyric acid contributes to gut structure by stimulating villi length, enzyme activity, and hence increases absorption rate of calcium in the gut. Coated butyric acid is protected in the gizzard, hence it makes passage without being digested and can reach he hind gut.

Calcium is available in Ovostrong, through Algeal limestone which will gradually release from gizzard to the small intestine. With the help of phytase and stimulated villiae, the absorption is effective and beneficial.

Aging is inevitable in laying farms, and it’s economically important due to reduction in laying performance and digestive capacity. This is more critical at ages above 50 weeks, depending on different breeds. Of course particularly optimization is necessary even more in older ages.

Ovostrong is formulated to supply all needs, to support laying performance and it is a great help to support peak of production.

Number of 1512 laying hens (Dekalb White) with known negative history of force molting were investigated in this study for 22 weeks. The flock was at age of 80 weeks and had a history of 55% production (Hen per day). Flock was divided to three different treatments under same conditions using a completely randomized design and were allocated to 126 cages with 4 birds per cage (504 birds per treatment).

 

Untreated group: Control

Treatment B: Dietary inclusion with Ovostrong

Treatment C: Dietary inclusion with Ovostrong and feed reformulation according to matrix

 

Evaluated variables:

 

a)      Total egg production

b)      Average daily egg production

c)       Day production per hen (%)

d)      House production (%)

e)      Eggshell thickness

f)        Egg yolk color score

g)      Mortality rate

h)      Feed efficacy per egg production

i)         Income over feed and medication cost

 

Results:

 

Treatments with Ovostrong (B and C) showed positive effect on total egg production, average daily egg production, day production per hen, house production and egg yolk color score with the highest production for treatment B, as 40253, 258.03, 55.98%, 51.92% and 7.85 respectively.

Eggshell thickness (mm) showed significantly (P ≤ 0.05) thicker and similar shell thickness in both groups B and C (0.334 ± 0.03a).

 

Mortality has not changed across the treatment groups. However, soft-shelled eggs decreased drastically by adding Ovostrong and the less amount of soft-shelled eggs, were for treatment C. Table 1.

 

Feed efficiency was observed and it is shown that treatment B had the most efficient feed conversion with a value of 2.41 kg of feed for every 12 pieces of eggs for the whole experimental period. This is followed by treatment C with 2.56, and with a slight difference in treatment A with 2.60.

 

Adding Ovostrong was effective on gross income over feed and medication cost. Treatment C was the most cost-effective group (Higher value) following by treatment B.

 

Conclusion:

 

It is concluded that feed inclusion with Ovostrong have positive effect on laying performance in general, inspite of the advanced age of the layers. This will yield higher profit for the farm.
