Trial work on milking sheep carried out at the University of Salamanca, Spain using the Denis Brinicombe Group Orvec Super Tup supplement has shown an increase in ewe fertility of over 17%. An additional unexpected benefit was that there was a substantial increase in milk yield and, although less significant for milking sheep, there was also an increase in multiple births.

Orvec Super Tup is formulated to be an aid to fertility. The supplement contains a full range of minerals, trace elements and vitamins, with the zinc, selenium, manganese and cobalt in 'protected' forms.

The results of the trial, based on a flock of 174 milking sheep, have just been released. The results show significant benefits that are applicable to all classes of breeding ewe, regardless of location or management system.

At the conclusion of the trial the researchers were unequivocal in their remarks that, "The treatment with supplemental corrector [Super Tup] proved to be significant on fertility, with a difference of 17.4% compared with the Control Group."

Additionally they reported that, "The treatment also proved significant on milk production with a positive differential of 81ml [per day] for milk [production] for the treated batch compared to the control batch." This figure represents an increase of 10 litres per lactation per ewe.

The report also observed that although the result was not statistically significant, there was an increase in the number of twins born in the Treatment Group.

"This trial work has shown that Orvec Super Tup lives up to the claims that we have made for it in the past," said James Brinicombe, Group Director. "Super Tup has been available from the Group for some years now and during that time we have always had positive feedback on its effect in flocks but now, with this trial work by Salamanca University, we can put precise figures on the effect of our unique product."

"Although the trial work at the University of Salamanca was carried out on milking sheep we are confident that the results transfer to the UK flock in as much as the positive comments we have received over the years have been mirrored in the trial with the ewe fertility improvement and the increase in multiple births, both of which are important to the UK flock," concluded James.

The ewes were randomly divided into two groups, the Control Group and the Treatment Group. Both groups received the same ration, grazing time and supplemental feed. The Treatment Group received Super Tup for a period of 30 days pre-tupping and during the service period. The Control Group was offered a standard mineral package over the breeding cycle.

Both Groups had the same grazing time, on two separate plots of ryegrass. When housed they were fed a diet of one kilo of alfalfa, 200gm of oats, 250gm barley, 100gm peas and the Control Group received 20gm of a standard mineral, while the Treatment Group had Super Tup on offer - taking an average of 20gm/head/day.

The part of study relating to fertility took into consideration two effects; treatment and the age of the ewe and the second part of the study, relating to milk production, took into consideration treatment, age of the ewe and month of lactation.

Orvec Super Tup contains a unique formulation of minerals, trace elements and vitamins along with Orvec Stimulus, which all help to stimulate the ewe into oestrus, the aim being to improve overall fertility and tighten up the lambing period.
