The implemented research subjects

Unit of Poultry Breeding conducts the studies on poultry meat and egg quality. The studies concerning egg quality include analysis of factors, affecting morphological composition of eggs and, in particular, the quality of shell during the second period of laying period, depending on nutrition of hens. In the nutrition of hens, various feed additives are employed; they improve calcium conversion.

The studies on meat performance concern production results, quality of the product, composition of microflora of alimentary tract and the problems connected with the health state and the reasons for culling of the birds in the flock.

The studies concerning biology, conformation and production results and the quality of meat and eggs of the sole decorative hens in Poland, i.e. Ayam Cemani are a novelty in the Unit. Besides it, the research work is carried on production of crossbred of Ayam Cemani x Sussex with the aim to investigate the heritability of the carcass’ colour.

For many years, the Unit has been specialized in conducting the experiments with the application of modern, available feed additives and evaluating their effectiveness and their impact on the quality of the product.

Poultry Farm

The Unit has a modern experimental base at its disposal; it is situated at the territory of Agricultural Experimental Plant Wilanów in Obory (11, St.Kostki Potockiego str., 02-958 Warsaw, Experimental Breeding Centre Obory – Goździe, tel. 22 754-13-87, fax. 22 754-13-87) where, in one building with area of 1000 m², there are separate compartments, indented for management of hens of different types in cages and on litter, for management of laying chickens and for broilers. The mentioned building is equipped with the modern system of heating and ventilation; there are individual cages for hens and the improved collective cages. In total, the farm may keep 2000 chickens and 500 laying hens.

In the discussed centre, the experimental work, implemented by the employees of the Unit, candidates for Ph.D. and M.Sc. degree, is carried on. Certain work, ordered by feed companies or other institutions are conducted, as well. In the years 2008 – 2010, the following ordered studies were implemented:

1. The effect of Ronozyme WX in laying hens;
2. The effect of the addition of Hy-D preparation on production results, dressing percentage, quality of broilers’ meat and strength of femural bone;
3. Effect of addition of Crina Poultry+300 preparations to feed for broilers on the rearing performance;
4. Effect of addition of Roxazyme G2 at the minimum dietary inclusion level (50 ppm) on performance of broiler chickens;
5. Torelance study of Roxazyme GX in laying hens;
6. The effect of Ayucal preparation on of eggshell strength;
7. Effect of addition of Ronozyme ProAct on performance of broiler chicken.
