Lambing Frequency in the Ile de France, Suffolk and Babolna TETRA Stocks of Babolna c.o., Szendrő
Published May 4, 2004
29-32

Lambing frequency of three different genotypes was evaluated in the breeding stock of Babolna c.o. Szendrő. Ile de France, Suffolk and Babolna TETRA breeding ewes gave the data for the further evaluation. The main aim of this research was to find out if there is any significant effect of selected parameters (registration class, lambing season,... lambing type and the years) on the lambing frequency, the period between consecutive lambings. Production parameters of 9,471 Ile de France, 1,244 Suffolk and 7,618 Babolna TETRA ewes were collected and processed. The analysis covered the period between the years 1989-1999. It was concluded that not all of the evaluated parameters had a significant effect on lambing frequency. Not all of the genotypes showed significant differences, according to the examined parameters.

Study of the rams’ jumping order
Published December 1, 2010
59-62

The bevahiour of Babolna Tetra, Ile de France and Suffolk rams was studied at semen collection by artificial vagina. The sequence of rams coming out of the group to the place of semen collection and the number of jumpings needed to ejaculation were observed. It was investigated if there were changes in these characters at different occasions, a...nd did they show connection to the body condition. The number of jumpings before ejaculation was different in the different breeds. Semen was taken at the first jump from 63% of the Suffolk, 56% of the Babolna Tetra and 55% of the Ile de France rams. There was no early ejaculation at the Ile de France, but it was common among the Suffolk rams. The greatest changes in the jumping order between different semen collections were observed in the Babolna Tetra breed. There was a medium correlation in the Suffolk breed between the jumping order and body condition in the autumn and spring, which was tight and significant in winter.
