El-Battawy National Research Centre, Animals Reproduction, Cairo, Egypt This investigation was carried out to study the impact of rbST administration on the levels of progesterone, estradiol-17ß and insulin like growth factor-1 in Baladi goats. Eleven Baladi goats aged 2-3 years were used in this investigation after being assigned randomly into three groups. First group (rbST+LH group, n=4), each goat was injected SC with 10mg rbST in 2ml buffer saline daily, starting from day 5 of synchronized estrous cycle till day 12 of cycle then S/C pregnyl (LH) was injected at a level of 275 I.U. per animal while each animal in the second group (rbST group, n=4) was administered only rbST as previously mentioned. A third group (n= 3) served as control. Goats were exposed to mature, fertile bucks daily and blood samples were collected daily. Results indicated that the progesterone concentrations and estradiol-17ß. In conclusion, this study confirmed that the administration of rbST increased the levels of progesterone, estradiol-17ß and IGF-I 827 Stimulation of Oestrous Activity of Female Goats Exposed to Long Days Treated Sexually Active Males in Different Months of Seasonal Anoestrous J. Flores, E. Carrillo, F. Veliz, H. Hernanadez, J. Delgadillo Centro de Investigación en Reproducción Caprina, Universidad Autónoma Agraria Antonio Narro, Departamento de Ciencias Médico Veterinarias, Torreón, Coahuila, Mexico Objective: This study was carried out to determine the response of female goats to male effect in different months of seasonal anoestrous using sexually male goats treated with continuous long days and untreated males. Material and Methods: In three months of seasonal anoestrous (April, May and June), three groups of anovulatory does (a group each month) were exposed during 15 days to males rendered sexually active with a treatment of continuous long days (16 h light/day), while other three groups of does (a group each month) were exposed to untreated males that only perceived the natural variations of photoperiod (26°N). The oestrus was detected twice daily during 15 days. The sexual behaviour of males (nudging, mount intention and complete mounts) was recorded during 2 h in the first 5 days after male introduction. Results: In April, the proportion of females showed oestrous behaviour was higher in does exposed to treated (18/19) than untreated males (0/20; P0.05) between does stimulated with treated (20/20 and 18/20, during May and June, respectively) and untreated males (19/20 and 18/19, during May and June, respectively). The sexual behaviour of the males treated with continuous long days was greater than the control males (P0.05). Conclusions: These results show that oestrous activity of female goats can be stimulated during April only when sexually active males are used. In contrast, during May or June, the response of females is similar when exposed to treated or untreated males. The lack of difference is likely to be due to the onset of the natural sexual activity of untreated males, which start in May.

Elizundia 2 , H. Hernandez 1 1 CIRCA, UAAAN, Torreón, Coahuila, Mexico 2 Dirección Particular: Angel Camino 161, Col. Valle del Nazas, Gómez Palacio, Durango, Mexico Objectives of the study: The aims of the present study was to investigate 1) if artificial long days (16 h of light/day) during winter 140 XXV. Jubilee World Buiatrics Congress 2008 may increase the milk production in Saanen goats from subtropical region and 2) if the milk production is maintained after remove the photoperiodic treatment. Materials and Methods: To this end, we used two balanced groups of Saanen goats with regard to date of parturition, initial milk production, parity, live weight and condition score. Starting on December 16 th (day 8 ± 0.6 postpartum; mean ± sem) one group of goats (n=19) was submitted daily during first 70 days of lactation to artificial long days (16 h light /day; Treated group), followed by the natural short days. Simultaneously, another group of goats (n=19) were maintained under natural variations of photoperiod (nearly 10 h and 19 min of natural light/day during winter solstice; Control group) during first 134 days of lactation. In both groups the weaning of the kids was performed at 30 days postpartum. All goats were maintained under intensive conditions and were fed alfalfa hay (with 18% of CP) and commercial concentrate (14% CP). Each two weeks, in all animals milk production in a 24 h-period were assessed through two machine milking 12-h apart up to 134 days postpartum. Results: Before the weaning of the kids, milk production did not differ significantly between the two groups (3.1 ± 0.1 kg in both groups; P>0.05). In contrast, at days 42, 56 and 70 post-exposition, goats from long days treated group yielded in average 3.0 kg of milk/day, and goats from control group only 2.5 kg of milk/day (P
2 Veterinary Medicine Faculty, Dept. Physiological, Biochemical and Cellular Sciences, Sassari, Italy Objectives of study: Energy metabolism is a key factor supporting cell functions and male gamete require exceptionally more ATP than other cell types in order to sustain its high queue activity. The aim of this study was to evaluate the relationhips between ATP concentration, viability and motility in fresh and cryopreserved-thawed spermatozoa during the breeding season. Materials and Methods: During the breeding season, semen was collected by artificial vagina from three bucks originating from native stocks in Ogliastra area of Sardinia. Semen was cryopreserved in 4% glycerol, cooled to 4 °C, frozen in 0.25 ml pellets on dry ice and then plunged into liquid nitrogen. Fresh and frozen/thawed semen samples from the three males were evaluated for viability by PI fluorescent staining and for progressive motility by Sperm Class Analyzer (v. 3.2.0. Microptics S.L., Barcelona, Spain), while ATP levels were measured spectrophotometrically at 340 nm using NADH-linked enzyme-coupled assays (H.U. Bergmeyer, Principles of enzymatic analysis, Academic Press, New York ,1974) modified for being adapted to the our system. Data were analysed using Statgraphics Centurion XV (Statpoint, inc). Results: Our data show that both ATP, progressive motility and viability do not differ between subjects nor between ejaculates in both fresh and frozen semen (Anova; P
