KOLOS AGRO LTD. has the pleasure to introduce itself...

Our company, KOLOS AGRO LTD. has been established in 1989 by 51 % Danish and 49 % Hungarian founders, for the primary purpose of goose production. The Ltd. has among its emplovees the representatives of all the phases of goose production, including researchers, goose breeders, production plants, poultry processing companies as well as foreign traders.

It has been our objective to improve all the economic values of the goose. The breeding work aimed at higher meat yield, slaughtering features, meat quality is performed by us with the help of computer tomograph at the Animal Breeding Faculty of Pannon University of Agriculural Sciences in Kaposv r. The necessary software had been developed by the researchers, mathematicians of the university under the guidance of Academician Dr. P‚ter Horn, vice-chancellor of the university. KOLOS AGRO Ltd. has purchased the goose software and we are now the exclusive owners and users of that software.

We intend to utilise the favorable effects of hybridisation in goose breeding also, and so we are working on the development of male and female lines.Our breeding objectives aimed at improving genetic characteristics can be summed up as follows:

• to increase egg production, fertility , hatchability, in other words mother lines of higher reproduction rate,
• to maintain the meat mass ( it would not be justified to increase it),
• to improve slauther features, in other words while maintaing outstanding growth features the development of male lines with favorable body composition, including
• to increas the uniformity of bodyweight,
• to improve the slaughter yield,
• to improve the meat : bones ratio,
• to increase the mass of valuable meat cuts ( breast and thigh), their ratio in the body mass ,
• to reduce fat content, especially fat under the skin, and to reduce abdominal fat mass,
• to reduce water content in the muscle in case becomes justified by the results of later studies.

Summing up, our objective is to change genetically the body composition of meat geese. For that purpose we have the most up to date, highest technology internationally available , namely the above mentioned X ray computer tomograph (RCT). Here a solution was found, the first internationally, when RCT has been put to use in animal improvement so that human diagnostics studies have also been made possible.

The use of RCT has made it possible that the animals intended for breeding should be selected based on their own performance.With the help of the instrument cross section exposures are made in points considered as best. Those pictures enable us to read very exactly the composition of the body textures of the goose, that is the muscle, bone, fat and water contents. This the body composition can be determined in vivo without damaging the bird. The key components of the body are among the inheritable features. The selection made based on own performance increases the safety if the selection of the birds most suited to breeding, and significantly accelerates breeding work.

The pictures received by the RCT method are evaluated with the help of computer. To illustrate the safety in selecting the most appropriate birds, it is enough to mention, that we evaluate, analyse approx. 1000 data, ratios for each gander. Of that great number of data the computer prepares in a matter of seconds the ranking of the geese in accordance with the given features and the best ones on the list can then be used as breeders.

The KOLOS geese have excellent genetic background and as a result of the breeding work its production indicators are of international standard. The two geese type we sell bring the following yields when bred under optimum farming conditions ( genetic abilities are some 15 % higher):

1. KOLOS WHITE GOOSE

This type of goose has white feathers, rapid growth rate, good feed utilisation capacity, is of excellent meat form, has favorable meat : bones ratio and is a low fat goose for broiler. It has large body mass, easy to cut, easy to remove the feather and produces plenty og feather with high down content goose for roast. It has high resistsance , its health is stable, and is eary to grow. Its parameters are as follows:

1.1. KOLOS WHITE parent stock goose ( their goslings specialised to meat and feather production)

Sex rate: 1 : 3 , 1 : 4
Mortality: 3 - 4 % / year
Selection: 4 - 5 % / year

1.2. KOLOS WHITE broiler goose ( can be slaughtered at day 56 )

1.3. KOLOS WHITE meat and feather producing goose ( can be slaughtered at week 26 or 32 )

2. KOLOS GREY GOOSE

This type of goose has grey feathers, rapid growth rate, excellent feed utilisation capacity, sands forced feeding excellently, and on its effect produces liver of excellent quality and quantity.
Its parameters are as follows:

2.1. KOLOS GREY parent stock goose ( their goslings specialised for liver production)

Mortality: 2 - 3 % / year
Selection: 5 - 6 % / year

2.2. KOLOS GREY liver goose ( can be slaughtered in week 11 - 12 )

We deliver the geese every year in the period between February and June at the age of one day ( or as requested).
Should we establish business relations we offer the following services:

• - expert consulting on location, farm management based on special agreement,
• - assistance, conultating in designing and building farms, hatcheries, their reconstruction,
• - transfer of technologies adapted to breeding and growing KOLOS geese, development of feed mixes, continuous consulting services,
• - consulting in animal hygiene,
• - training of workers ( employees on location or in Hungary).
