Megjegyzések:	Examinations on ostrich chick vitality can help to improve the effectiveness of Hungarian ostrich husbandry and hatching technology. The investigations were carried out on an ostrich breeder farm in Eastern Hungary. For the analyses, the Tona et al. (2003) scoring system was applied presenting eight main criteria (activity, feather, condition, eyesight, the condition of navel and leg, the amount of the remaining shell membrane and egg content, and the size and tenderness of the abdomen). Most chicks (98.08%) were vigilant and had clean and dry feathers. There was no difference between the average hatching weights between May and August but a decreasing tendency was shown during the laying season. The vitality total score was above 90 in each evaluated month and was not affected by the hatching month. Our results revealed that the vitality of chicks was not affected by either the hatching month (P=0.51) or the weight category (P=0.11). Neither the hatching weight of chicks and leg condition were correlated (P=0.79). Results showed that the Tona scoring system with small modifications can be well applied to ostrich chicks. Practical on-farm usage of the system can be suggested as an aid in day-old chick evaluation. After individual marking of chicks, the investigation of growth and culling rate could be carried out for more precise conclusions, involving more farms and laying seasons.

Cím:	Effect of noninvasive castration method on weight gain, behavior and meat quality of ram lambs / Gabriella Novotni-Dankó, Rebeka Czoller, Zsófia Rózsa-Várszegi, Péter Balogh
Dátum:	2022
ISSN:	1587-1282
Megjegyzések:	In the course of producing heavyweight lambs (above 35 kg), males need to be separated from females at the end of the fattening period. If not, the rams must be castrated because they reach sexual maturity, and their activity bothers the ewes or unwanted pregnancy may occur. The present study surveys if the Hungarian sheep keepers know or use the non-surgical elastrator method for castration and assess the effect of castration (surgical and non-surgical) on daily weight gain, behavior, moving activity, and meat quality of rams, respectively. We found many advantages regarding the use of the elastrator method. Based on the survey results, 100% of farmers who used elastrator had a positive experience and favorable opinion about this method. There is no need to separate the rams, which allows for less area requirement and more economical technological conditions. The traditional castration (with a knife) process is longer (4?6 minutes), and caused longer-lasting stress while the elastrator application is bloodless, took only 20-30 seconds, and were stress-free. The number of steps of ring-gelded individuals was much lower than that of the non-castrated rams. The difference in steps number could also be seen in ewes separated into different ram groups. The weight gains of individuals castrated by the ring were better than the surgically castrated ones and also individuals with testicles. The palatability of the meat from the non-castrated group was less favorable, and the chewiness of the ringed group was the best. Finally, our results highlighted the benefits of the noninvasive elastrator method in animal welfare aspects.
