The Number and Species of Migrating Wild Geese in Hortobágy
22-25Views:94This paper presents the total number and annual distribution of wild geese population on Puszta Hortobágy. Two migrating goose species, White-fronted Goose (Anser albifrons) and Bean Goose (Anser fabalis) contribute most to the total number of geese population. Feeding place selection of goose depend on the season. In autumn and winter, croplands largely provided food for geese. Due to selections among fields and parts of the field, sometimes relatively high grazing pressure for the whole area may be severely multiplied in some cases resulting potentially 100% shoot defoliation on the frequented sites of a wheat field.

Effect of feeds with different crude fiber content on the performance of meat goose
5-8Views:314In the last 50 years, poultry meat production has increased dynamically. The role of crude fiber content in feed is unclear based on a small amount of literature about goose feeding.
The aim of theis experiment was to determine how various crude fiber content (55; 60; 65g crude fiber/kg feed) influences the performance of meat geese in the second phase of the rearing period. 150 goslings (3 treatments, 5 cages/treatment, 10 birds/cage) were included in the test. The experiment started and finished at the age of 21st and 63rd day, respectively.
The obtained results suggest that various crude fiber content did not influence the performance of meat geese significantly; however, a feed of 55g crude fiber/kg resulted in better fattening results (final body weight, body weight gain, specific feed protein and energy conversion rate). In addition, compound feed of 65g crude fiber/kg proved more favourable with respect to cost-efficiency. Based on the obtained results so far, further models and farm experiments are required.

Goose Production Responses to Grass-Based Diets
26-28Views:100A feeding trial with 4 week-old goslings was conducted in 2003 using different proportions of chopped grass and grain pellets in the diet. Proportions of chopped grass and grain pellets in diets for Treatments 1, 2, 3 and 4 were 25:75; 50:50; 75:25 and 0:100, respectively. Weekly and final live weights of geese and the feather quality were measured. Treatments with higher grain contents produced higher live weights, and better feather quality.

Preservation of Biological Diversity of Domestic Animals in Hungary
18-29Views:95Since the 1992 Rio de Janeiro UNO Congress domestic animals belong also officially to the genetic diversity of the world. Non commercial domestic animal breeds should be maintained for many cultural and technical reasons. Conservation and preservation of living beings is nowadays in the programme of many regional, national and international organizations.
The preservation of domestic animals is possible in situ (at the original place and conditions) and ex situ (by cryogenic methods).
There are three era in the history of preservation of domestic animals: the epoch of spontaneous maintenance, the period of sporadic national activities and the era of international programme.
Some of the questions to be solved by scientific research: the principles of selection of the candidate populations for maintenance, the different degrees of endangeredness, the necessary population size to be subsidized, the problem of inbreeding, the best mating systems etc.
In Hungary the maintenance of endangered domestic animal breeds is based upon the low.
The following breeds are on the list of protected breeds:
− the Hungarian Grey cattle,
− the Lipizzan, Shagya, Nonius, Gidran, Furioso,Kisbér Halfbred, Murinsulaner and Hucul horses,
− the Racka, Tsigai and Cikta sheep,
− the Mangalitsa pig,
− the Hungarian yellow, white, speckled and the Transsylvanian naked necked hen,
− the Bronze Turkey,
− the Frizzle Feathered goose.
Hopefully in the near future the breeders of traditional domestic animal breeds will find the possible niches for their special products. -
Effect of different lysine-metabolized energy ratio on performance of meat-type geese
39-42Views:185The aim of the experiment was to determine, how the different ratios of the digestibility lysine/ metabolized energy (0.82, 0.87, 0.91 g DLYS/MJ AMEn) of the feed influence the performance of geese. There were 150 goslings (3 treatments, 5 cages/treatments, 10 birds/cages). The experiment has started and finished at the age of 3 and 9 weeks, respectively.
The results of the experiment showed, the different ratios of DLYS/AMEn (0.82, 0.87, 0.91 g DLYS/MJ AMEn) did not influence the performance of young geese. Better growth performances were found for the 0.91 g DLYS/AMEn feed (feed intake, body weight gain, feed and energy conversion rate). This treatment coincided with high feeding costs. Based on these results we need more models and farm experiments to prove this tendency. -
The Role of Grasslands in the Diet of Geese
19-21Views:84A feeding trial was conducted with 4 weeks old growing geese. Feeding treatments were different proportion of chopped grass and grain pellets. Daily DM intake, weekly live weight gains and final live weight was measured. It is concluded that 25% of chopped grass in the diet has similar result as only grain pellet diet. This is good for the economy of goose production.
