Guinea fowl (Numida meleagris) has existed in the Carpathian Basin for centuries and now is becoming an important genetic resource for low-input production. This study aimed to compare production traits, such as livability, BW, and feed conversion, of 3 Hungarian Landrace Guinea Fowl (HLGF) ecotypes, 2 from Hungarian gene banks (Godollo (G) and Hortobagy (H)) and one local type from Central Hungary (C). Beyond 5 wk of age, birds were kept in enclosures of either 15 m2 or 50 m2 free-range area per bird. The highest average BW and lowest feed conversion at 14 wk of age (1329.38 ± 101.47 g and 2.916 ± 0.253 kg feed/kg BW gain, respectively) were recorded for the G ecotype of HLGF, which was kept in 50 m2 free-range area/bird. An ANOVA test showed that the ecotype of Guinea fowl influenced BW and feed conversion, and the size of the free-range area was found to be a determining factor for feed conversion rate at 14 wk of age (P < 0.001). Our study results indicate that use of the G ecotype of HLGF is preferred for meat production and that the size of the free-range area is essential for keeping any types of HLGF after 5 wk of age. Different HLGF ecotypes also were shown to exist in rural Hungary, which should be of interest to future conservation programs. © 2015 Poultry Science Association Inc.

Vietnam enjoys the richest natural resources and favourable conditions for agricultural development including poultry production. Backyard chicken production is considered as a traditional system in Vietnam, as it has a short production cycle and requires low investment. Despite the increase of semi-intensive and intensive farming, the self-sufficient backyard farming system is still practised by 84-85% of rural families in the Northeast-Northwest of Vietnam and approximately 42-71% of those in the Southeast-Mekong River Delta regions. Breeds raised in such systems are mostly popular local chicken breeds which accounted for over 70% of the country's total chicken population in 2007. In this paper, more than 30 native Vietnamese chicken breeds with their origin and endangered status are listed and the breeding traditions related to these native breeds are discussed. Moreover, some proposals are given for a particular conservation strategy regarding the possibilities to utilise the native Vietnamese chicken breeds in sustainable rural farming. It has been concluded that governmental conservation efforts should meet the natural way to save the local native breeds by local inhabitants. In this way, a sustainable on-farm chicken conservation pattern can be elaborated not only for Vietnam but also for the countries or regions which have similarly rich, valuable biodiversity, agro-biodiversity and agricultural traditions. For this, local researchers should be encouraged to study economic traits, veterinary status, and all special characteristics of the local breeds in the frames of an official, national gene conservation programme. © World's Poultry Science Association 2015.

This paper aims to describe the pattern and compare the egg production of conservation flocks of seven traditional Hungarian chicken breeds: Yellow Hungarian (YH), White Hungarian (WH), Speckled Hungarian (SH), Partridge coloured Hungarian (PH), White Transylvanian NakedNeck (WT), Black Transylvanian Naked Neck (BT) and Speckled Transylvanian Naked Neck (ST). Data were collected at the Research Centre for Farm Animal Gene Conservation (HáGK). It was observed that egg production was comparably high in WH and YH and low in ST. The Transylvanian hens produced fewer eggs during wintertime than the other groups. The egg-producing pattern of hens hatched in spring showed similarity with two main hills in most of the breeds. The significant difference between the 1st and the 2nd laying periods was found only in SH, WH, ST, and BT chicken breeds. The ST and BT hens produced significant higher number of eggs/day during the 2nd laying period than during the 1st one (0.306 vs. 0.416, p < 0.050 and 0.319 vs. 0.379, p < 0.050 respectively). Meanwhile, the SH and WH hens laid a significantly lower number of eggs during the second-laying period than during the first-laying period (0.459 vs. 0.386, p < 0.050 and 0.427 vs. 0.384, p < 0.050 respectively). Understanding the egg production of these traditional chicken breeds may help to improve the utilization and involvement of not only the Hungarian chicken breeds with better performance but also all the other breeds efficiently in family farming, as well as the other sustainable agricultural production systems. © Verlag Eugen Ulmer, Stuttgart.
