The productivity of Cashmere goats depends on their reproductive performance, which, in turn, depends on their level of nutrition. Ovulation rate and pregnancy in sheep are both affected by nutrition, but little is known about the response of female goats (does) to supplementary feeding. The lupin group (n = 40) received 250 g lupin per head per day in addition to pasture whereas the control group (n = 40) received no nutritional supplement. Both groups were synchronised for 17 days with intravaginal progestagen pessaries. The supplement was fed for 21 days, commencing 7 days before the bucks were introduced and intravaginal pessaries were removed (Day –2). Does were expected to ovulate 2 days later on Day 0 and the bucks were removed on Day 3. Blood was sampled for progesterone every 3 days from buck removal (Day 3) until Day 18. Ovulation rate was assessed by trans-rectal ultrasonography on Day 13 and pregnancy was diagnosed by trans-abdominal ultrasonography on Day 61 of the experiment. Does supplemented with lupins had a numerically higher ovulation rate than does fed only on pasture, but this difference was not significant (1.76 ± 3.21 v. 1.52 ± 3.79; P > 0.05). Similarly, there was no difference in the numbers of does conceiving to the first service between the lupin and control group (89% v. 94%; P > 0.05). Progesterone concentrations on Day 12 were higher in does supplemented with lupins than does fed only pasture (6.29 ± 0.27 ng/mL v. 5.41 ± 0.27 ng/mL; lupin and control group; P < 0.05). In conclusion, lupin supplementation induced a numerical increase in ovulation rate but this difference failed to reach significance. Does supplemented with lupins had higher concentrations of progesterone during early pregnancy, which is the opposite effect to that previously reported in sheep.

This study investigated the efficacy of intrauterine infusion of a chitosan solution (CHT) on uterine recovery in early postpartum dairy cows with or without endometritis, and their subsequent reproductive performance. In Experiment 1, cows with endometritis at 3 weeks postpartum were administered CHT (n = 5) and prostaglandin F2α (PGF2α) (n = 4). Untreated cows (n = 7) served as the control group. In Experiment 2, 18 cows with a normally recovered uterus at the fresh cow check (mean, 35 days postpartum) were assigned to the CHT (n = 10) and control (n = 8) groups, and intrauterine infusion was conducted in the CHT group. Overall, in Experiment 1, the percentage of polymorphonuclear leukocytes significantly declined in the CHT group (32.3 ± 10.2 to 5.5 ± 2.4, p < 0.05) from week 3 to week 5, but no decline occurred in the PGF2α and control groups. In Experiment 2, the CHT and control groups showed no significant differences in reproductive parameters, suggesting the absence of adverse effects of CHT on fertility. These results suggest that intrauterine infusion of CHT in the early postpartum period effectively accelerates uterine recovery from endometritis and might be a suitable replacement for PGF2α administration.

ABSTRACTBorder Leicester × Scottish Blackface (Greyface) ewes of three groups, each comprising 118 animals in a wide range of body condition scores, were mated at a synchronized oestrus in mid October. The ewes were passively immunized against testosterone (group P), actively immunized against androstenedione (group F), or not treated (group C). All ewes were slaughtered at return to service or at 35 to 45 days of pregnancy and ovulation rates and numbers of embryos present were determined. Mean ovulation rates of ewes in group P were higher than in those in group C (P < 0·05) and this difference was evident at most levels of body condition. The absolute increase in ovulation rate, compared with the control group, was similar at all condition scores. Mean ovulation rates of ewes in group F were higher than those in group C (P < 0·001) and the magnitude of the increase was greater in ewes in higher condition scores. The incidence of ova wastage was variable but differences between treatments in mean ovulation rate were generally reflected in mean litter size. The conception rates of immunized ewes were depressed compared with those of control animals, particularly in ewes with a body condition score less than 3·0 at mating. Consequently, there was no improvement in the potential lambing rate of immunized ewes following only one cycle of mating. Circulating antibody titres were not related to conception rate or body condition at mating and were related to ovulation rate only in group F ewes. It is concluded that immunization against steroids, using either passive or active techniques, can improve the reproductive performance of individual ewes but improvement in the performance of the flock as a whole may only be achieved under optimal conditions of nutrition and season.

AbstractThe results obtained from a study model using Sepia 200c in a herd of dairy cows led to an extended study. Overall reproductive performance was monitored monthly by a farm action list and the technique of palpation of the ovaries per rectum was used to determine pregnancy and cyclical status. A total of 101 cows were randomly treated with Sepia 200c on day 14 or 21 postpartum.Statistical analysis of the results was based on the differences between the untreated Control and Sepia-treated groups in periparturient disorders and pre- and post-service periods, and between the two Sepia-treated groups.In the pre-service period, a significant difference was found between the sepia-treated groups in the proportion of heifers calved, the number of assisted calvings and pre-service problems compared to Control. A difference of 9.9 total mean days to oestrus post-treatment was found between the Sepia-treated groups.During the post-service period, significant differences were found in the conception rate to first service, the percentage of cows in calf and total culled.A reduction (non significant) was found in the 21-day treatment group compared to control and 14-day treatment in the mean days calving to conception interval and the calving index. However, between the Sepia-treated groups a significant difference was found in total mean days calving to conception interval.The results of this study appear to demonstrate a difference in effect between the Sepia-treated groups and Control group. The study has been extended into a double blind placebo trial to find the effect of using a placebo and assess the use of Sepia given earlier postpartum on herd reproductive performance.

Background: One of the conservative management of ureteric caculi is by medical expulsive therapy by targeting common causes of obstruction such as edema, ureteral spasm and infection which will favour expulsion of calculi. The objective of this study was to assess comparative efficacy and safety of medical expulsive therapy of ureteric calculi.Methods: This was a randomized, prospective, open label, comparative study. Subjects satisfying inclusion and exclusion criteria were randomized into 4 groups tamsulosin, nifedipine, progesterone and control. Medical expulsion of calculi of 6mm to 15 mm size was carried out in 120 patients. Patients were followed up on OPD basis every third day. Calculi expulsion until day 28 as confirmed by abdominal ultrasonography was taken as the end point.Results: Expulsion rate in tamsulosin group was 90%, whereas nifedipine, progesterone group were 83.33% and 70% respectively which was significant compared to control group which was 36.6% (p < 0.005). Expulsion time was also reported to be significantly less in these groups as compared to control group. Therapy related adverse effects were minor and were seen in only 6 patients.Conclusions: Medical expulsive therapy of ureteric calculi of size 6 to 15mm with Tamsulosin, nifedipine and progesterone were safe and efficacious and could be implemented for initial management in selected patients.

The present study evaluated the development of equine conceptus transferred to non-cyclic recipient mares treated with altrenogest. Twenty four mares were used as embryo recipients during the ovulatory phase (Control group; n=8) or anestrus/transitional phases (Altrenogest group; n=16) and were evaluated by transrectal ultrasonography, at five day intervals, to monitor the development of embryonic vesicles from 15 to 45 days of pregnancy and embryo proper/fetus from 20 to 60 days. Embryonic vesicle's features such as shape, embryo location within the vesicle and umbilical cord development were similar between cyclic and non-cyclic recipient mares. The embryonic vesicle and embryo proper/fetus growth was significant (P<0.05) between 15 and 60 days of gestation in Altrenogest and Control groups, except for days 20 to 30, where embryonic vesicle growth decrease was observed (P>0.05). The embryonic vesicle and embryo proper/fetus growth was similar (P>0.05) when gestational days were compared between groups. The similarity in conceptus growth between cyclic and non-cyclic recipient mares during early pregnancy indicates that the uterine environment of non-cyclic recipient mares treated with progestins provides similar conditions for the development of transferred embryos

AbstractOverall reproductive performance and associated periparturient disorders were monitored in a herd of British Friesian cross dairy cows from September 1987 to August 1988. Pregnancy diagnosis and cyclical status of the herd was determined by palpation of the ovaries per rectum. A total of 49 (110) cows were randomly treated with Sepia 200c either on day 14(19) or 21 days (30) postpartum.Statistical analysis of the results was based on the differences between the control and combined Sepia-treated groups. Although there were significant differences in the proportion of heifers calving in each group, there was no significant difference in periparturient disorders or during the pre-service period.However, in the Sepia Group that held a lower proportion of heifers, a significant difference was found in the conception rate to 1st service (47%), the percentage of cows in calf (90%) and total culling rate (10%) compared to the Control Group (26%, 72% and 28% respectively). A reduction (non significant) was found between the Sepia and Control services to conception (0.2), calving to conception interval (5 days) and calving index (2 days).The results of this pilot study appear to demonstrate a difference in effect between the Sepia-treated Group and Control Group. The study has been extended to treat a larger number of dairy cows to examine the reproducibility of these results.

Chromium picolinate (CrPic), which is used as a nutritional supplement and to treat type 2 diabetes, has gained much attention because of its cytotoxicity. This study evaluated the effects of CrPic on the viability of the chick embryo fibroblast (CEF) using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, morphological detection, and flow cytometry. The results show that lower concentrations of CrPic (8 and 16 μM) did not damage CEF viability ( p > 0.05). However, higher CrPic concentrations (400 and 600 μM) indicated a highly significant effect on the production of intracellular reactive oxygen species, alteration of mitochondrial membrane potential, intracellular calcium ion concentration, and the apoptosis rate ( p < 0.01), contrary to lower CrPic concentrations (8 and 16 μM) and control group. Moreover, apoptotic morphological changes induced by these processes in CEF were confirmed using Hoechst 33258 staining. Cell death induced by higher concentrations of CrPic was caused by an apoptotic and a necrotic mechanism, whereas the main mechanism of oxidative stress-induced mitochondrial dysfunction was apoptotic death.

In a first study, 231 cows with retained placenta (RP) were assigned to four groups and their reproductive performance after treatment was studied. Group 1 received 2.0 mg/kg ceftiofur hydrochloride (CH), 10 mg estradiol cypionate (ECP) and 100 IU oxytocin for three consecutive days (CEO-3; n= 63). Group 2 received the same treatment for six consecutive days (CEO-6; n= 48). Group 3 was treated with CH and oxytocin for three consecutive days (CO-3; n= 68). Group 4 was subjected to the previous treatment for six consecutive days (CO-6; n=52). The control group (n= 62) did not present RP. Conception rates (CR) did not differ between treatments with values of 36.5, 25.0, 30.9, 30.8 and 33.9% for CEO-3, CEO-6, CO-3, CO-6 and control group, respectively. Services per pregnancy did not differ between groups (overall 3.6 ± 2.0; mean ± SD). In a second study, changes in milk production associated with RP were examined in cows receiving the CO-3 protocol. Data came from 360 cows with RP and 1623 served as controls. Mean 305-d milk yield was 283 ± 43 kg lower (P<0.05) in cows with RP compared to controls. It was concluded that either prolonged (6-d) or short (3-d) application of CH in combination with oxytocin and ECP were equally effective in preventing a reduction of the reproductive performance in cows suffering RP. Additionally, RP was associated with a 3% decrease in 305-d milk production.

A study on reproduction of 52 Red Sokoto Goat (RSG) does was conducted to evaluate some aspects of their reproductive performance for clinical application and as an update. Does were randomly divided into 18, 18 and 16 as prostaglandin F2-alpha (PGF2α),  progesterone sponges (P4S) and control groups respectively. Double injection protocol of PGF2α, 12-days apart, and P4S inserted for 12-days were used to synchronize oestrus, while the control group received no treatment. Thirteen bucks were used, seven as breeders and six as heat detectors. Oestrus detection employed visual observation and apronisation. Standing to be mounted was the cardinal  sign of oestrus. Breeding was by hand-mating and at detected oestrus. Results indicated heterosexual and homosexual mounting, thin stringy clear mucous discharge and standing-to-be-mounted as signs of oestrus. Oestrus response rate was 100 %, 94.4 % and 75.0 %  for PGF2α, P4S and Control respectively; P4S retention rate was 94%. Effect of synchronization agent on on-set of oestrus was 15.86 + 0.73 h (PGF2α), 15.08 + 0.84 h (P4S) and 17.73 + 0.85 h (Control), while parity on on-set of oestrus was 12.12 + 1.87 h (first), 17.77 + 0.77  h (second) and 18.79 + 1.95 h (third). Effect of synchronization agent on duration of oestrus was 44.76 + 2.13 h, 45.78 + 2.46 h and 42.40 + 2.50 h for PGF2Α P4S and Control respectively, while parity on duration of oestrus was 42.26 + 5.48 h (first), 45.02 + 2.27 h (second) and 45.67 + 5.73 h (third). There were no significant differences (P > 0.05) for oestrus on-set and duration. Overall pregnancy and  conception rates were 65.4 % and 72.3 % respectively, kidding rate was 76.5 %, abortion rate was 23.5 % and late embryonic mortality rate was 26.5 %. Mean gestation were 146.29 + 1.59 and 146.63 + 1.64 for single and twin births respectively. Age, parity and body condition score of dam had significant effect on litter size (P < 0.05). It was concluded that some aspects of the reproductive  performance of the RSG does studied following oestrus synchronization with PGF2α and P4S had clinical application, good and acceptable. Key Words: Reproductive, Red Sokoto, Does, Prostaglandin F2-alpha and Progesterone.

Early postpartum cyclicity is related to subsequent fertility. This field study evaluated the effect of gonadotropin-releasing hormone (GnRH) administration around the first postpartum month on subsequent reproductive performance in dairy cows. Holstein dairy cows underwent ultrasonography at 30.0 (±6) days postpartum to determine the existence of ovarian structures including corpus lutea (CL), follicles, or cysts. The cows without CL were divided randomly into 2 treatment groups: GnRH group and control group. Cows in the GnRH group received an injection of 100 µg of GnRH (gonadorelin, Godorel, Uni-Biotech Co. Ltd., Korea; n = 151). Cows in the control group received no GnRH (n = 171). Cows diagnosed with endometritis at the time of ultrasonography were excluded from this study. Cows received the normal herd reproductive management program including estrous detection or synchronization, or synchronization of ovulation in the breeding period. The voluntary waiting period from calving to first AI in this study was 40 days. Pregnancy was determined per rectum 60 days after AI by both ultrasonography and palpation. Reproductive performance data were collected for a minimum of 210 days postpartum. Reproduction data between the GnRH and control groups were evaluated by chi-square test or the Cox proportional hazard model with the PHREG procedure using the SAS program (version 9.1, SAS Institute Inc., Cary, NC, USA). The number of days to first insemination after calving did not differ (P > 0.05) between the control group (80.9 ± 2.2 days) and the GnRH group (82.1 ± 2.3 days), while the pregnancy rate to first insemination tended to be higher (P = 0.1) in the GnRH group (42.3%) than in the control group (33.3%). Furthermore, the pregnancy hazard was higher by 210 days in milk for the GnRH group compared with the control group (hazard ratio = 1.33; P < 0.05), which resulted in a 26-day reduction in the median interval to pregnancy. In conclusion, the administration of GnRH around the first postpartum month improved subsequent reproductive performance in dairy cows. This work was carried out with the support of the Cooperative Research Program for Agriculture Science & Technology Development (project no. PJ008464) Rural Development Administration, Republic of Korea.
