Pharmacological Method

The aim was to estimate the effective pharmacological method of the estrous cycle synchronization by checking the effects of synchronization by measurement of progesterone (P4) and 17-beta estradiol (E2) concentration by RIA and artificial insemination. The experiment was performed at the red deer farm in Rudzie (North-East Poland; 3 year’s old). The herd (N = 14) was kept away from bulls and was divided in two groups of seven animals. In the Group I, CIDR insert (0.3 g of P4) was applicated intravaginally for 12 days; a second insert replaced the first one for the next 12 days, and next 200 IU of equine chorionic gonadotropin (eCG) was injected intramuscularly (Folligon). Estrus was expected 48 h after eCG injection. In the Group II, Chronogest sponge (20 mg of flugestone acetate) was applicated intravaginally and after 7 days replaced with second chronogest sponge for 7 days. After removing the sponge, on the same day eCG was injected and estrus was expected after 48 h. Artificial insemination was provided with frozen-thawed semen twice: 12 and 24 h after expected estrus. The peripheral blood from the jugular vein was collected each time when the inserts or sponge were applicated and 40 days after insemination. The concentration of P4 and E2 in plasma was measured by RIA. The effectiveness of insemination was monitored by pregnancy-associated glycoproteins determination and observed by the number of calves born. Two pregnancies were confirmed in Group I and five in Group II based on PAG concentration. One newborn was observed in Group I and five in Group II. Both methods of synchronization are effective in hinds based on the received profile of steroids. Although the sponge shape in case of chronogest is better comparing with CIDR, which was not completely deposited in the vagina of hind, potentially leads to bacteria inflammation, and it disturbs the rightful endocrine regulation. Moreover, pregnancy rate and hormone responsiveness were better in Group II.

AbstractGenetic and phenotypic parameters were estimated for farmed red deer (Cervus elaphus) in an upland environment in the north-east of Scotland. Genetic parameters were estimated using restricted maximum likelihood analyses. Heritabilities of pre-weaning traits associated with growth were moderate for birth weight (0·27 (s.e. 0·04)), weaning weight, generally in September at 3 months of age (0·21 (s.e. 0·06)) and growth rate from birth to weaning (0·15 (s.e. 0·03)). Heritabilities for post-weaning traits were 0·10 (s.e. 0·05) for turn-out weight in April/May, 0·14 (s.e. 0·06) for September weight, at 15 months of age, 0·08 (s.e. 0·05) for growth rate weaning to turn-out and 0·12 (s.e. 0·06) for growth rate turn-out to September. Correlations between weaning weight and post-weaning traits were high indicating the usefulness of weaning weight as a selection criterion for red deer on upland farms. While Wapiti (Cervus elaphus canadensis) crosses grew faster than pure red deer they also tended to have higher mortality rates pre-weaning. Older dams were more likely to have a successful pregnancy and also tended to calve earlier. Date of calving was found to show no heritable variation in this study.

Taxonomic Relationships

During the nineteenth century, scientific literature and official reports recorded the occurrence of a population of red deer, Cervus elaphus, on the island of Lampedusa (Pelagian Archipelago, Italy). Osteological specimens collected by the zoologist Enrico Hillier Giglioli towards the end of the century confirmed these references. Since cervids are not found among the fossil fauna of the island, the red deer must have been introduced by man although we do not yet know precisely when. The former existence of the species on Lampedusa is discussed by comparison of literary material and bone evidence. The population's probable origins and its taxonomic relationships with other Mediterranean red deer populations are also analysed.

The role of interferon in early pregnancy in red deer was investigated by (a) measuring production of interferon by the conceptus, (b) testing the anti-luteolytic effect of recombinant interferon-tau in non-pregnant hinds, and (c) treatment of hinds with interferon after asynchronous embryo transfer. Blastocysts were collected from 34 hinds by uterine flushing 14 (n = 2), 16 (n = 2), 18 (n = 8), 20 (n = 13) or 22 (n = 9) days after synchronization of oestrus with progesterone withdrawal. Interferon anti-viral activity was detectable in uterine flushings from day 16 to day 22, and increased with duration of gestation (P < 0.01) and developmental stage (P < 0.01). When interferon-tau was administered daily between day 14 and day 20 to non-pregnant hinds to mimic natural blastocyst production, luteolysis was delayed by a dose of 0.2 mg day(-1) (27.3 +/- 1.3 days after synchronization, n = 4 versus 21 +/- 0 days in control hinds, n = 3; P < 0.05). Interferon-tau was administered to hinds after asynchronous embryo transfer to determine whether it protects the conceptus against early pregnancy loss. Embryos (n = 24) collected on day 6 from naturally mated, superovulated donors (n = 15) were transferred into synchronized recipients on day 10 or day 11. Interferon-tau treatment (0.2 mg daily from day 14 to 20) increased calving rate from 0 to 64% in all recipients (0/11 versus 7/11, P < 0.005), and from 0 to 67% in day 10 recipients (0/8 versus 6/9, P < 0.01). The increased success rate of asynchronous embryo transfer after interferon-tau treatment in cervids may be of benefit where mismatched embryo-maternal signalling leads to failure in the establishment of pregnancy.
