Significant Difference

The objectives of the study were (a) to study the characteristics of uterine involution in ewes that had developed subclinical uterine infection in the immediately post-partum period and (b) to evaluate effects of the infection in the subsequent reproductive performance of ewes. Uterine infection was induced in ewes (I, n = 10) by intrauterine inoculation of Escherichia coli; uninoculated controls were included (C, n = 12). Animals were examined at regular intervals before and post-inoculation. Clinical and ultrasonographic examinations were performed. Vaginal swab samples and biopsy uterine tissue samples were collected for bacteriological, cytological and histological examination. Finally, ewes were put to rams and reproductive performance was monitored. After challenge, it was ultrasonographically found that caruncular dimensions, myometrial thickness and diameter of uterine lumen were greater in I ewes. In these ewes, particular reduction of dimensions occurred during the second week post-partum, whilst in C ewes during the first week. The uterine artery diameter and the blood flow into the uterus were also greater in I than in C ewes. E. coli infection was more frequent and of longer duration in I than in C ewes: in 68.1% and 50.0% of ewes and 19.5 and 14 days, respectively. There was lower proportion of neutrophils and higher of lymphocytes in group I than in C. In inoculated ewes, there was histological evidence of uterine epithelial destruction, increased cellular infiltration, hyperaemia and extracasation, which persisted up to 42 days post-partum. During the subsequent reproductive season, all ewes in group I lambed normally and produced healthy and viable lambs. No significant difference in reproductive performance parameters were seen in I comparison to C ewes. It is concluded that the innate immunity of the uterus sufficed to counteract the bacterial infection, although the process of involution took longer than in healthy animals; moreover, the ultrasonographic examination is a useful means for assessment of the genital tract of ewes post-partum; finally, no adverse effects were noted in the subsequent reproductive performance of ewes.

SUMMARY Progestational agents were studied for their effects on collagenolytic activity and loss of collagen and wet weight from the involuting post-partum rat uterus. Administration of very large doses of progesterone (80–150 mg/day) significantly retarded uterine involution and loss of collagen. This was accompanied by a significant reduction in uterine collagenolytic activity. By 72 h post partum, uteri of rats treated with 150 mg progesterone/day had wet weights 30% above, collagen 85% above, and collagenolytic activity 45% below, those of the control uteri. Similar effects were produced by 17α-acetoxy-6α-methylprogesterone at the same dosage levels. However, the progestational agent 6α-chloro-17α-acetoxypregna-4,6-diene-3,20dione acetate had no effect in this system.

ABSTRACTNineteen pluriparous buffaloes of Nili-Ravi breed which calved during the months of October and November 1983 were studied for the effects of sucking stimulus on the uterine involution, post-partum ovarian functions and fertility. On the day of calving, buffaloes were assigned to either a limited-suckling (LS) or non-suckling (NS) group. Changes in reproductive organs were monitored by rectal palpations at weekly intervals. Buffaloes were observed for oestrus twice daily (04.00 and 18.00 h) with the help of a teaser bull, and were artificially inseminated at the first post-partum and each subsequent oestrus. LS buffaloes had a shorter period to uterine involution (20 days) than NS buffaloes (28 days). Intervals to regression of the corpora lutea of pregnancy and to resumption of post-partum follicular development did not differ in the two groups. LS buffaloes had longer intervals to first post-partum oestrus and conception (54 and 88 days respectively) than NS buffaloes (39 and 68 days respectively). However, the difference in services per conception of LS and NS buffaloes was non-significant (2-05 v. 1·62). These limited data reveal that the suckling stimulus has a negative effect on the post-partum resumption of oestrous activity, and that conception is delayed. Further studies are indicated to verify these observations in a larger sample size and during all seasons of the year.

Tenfold Increase

Treatment of parturient rats with 100 μg oestradiol/day caused a significant retardation of uterine involution and collagen breakdown. The post-partum uterus had a peroxidase activity of 180 μmol H2O2 reduced/min per uterus. Treatment with oestradiol caused an eight- to tenfold increase in this activity within 3–4 days. Treatment of rats with 4 mg cortisol/day commencing 3 days prepartum had no effect on uterine peroxidase activity but it blocked the oestradiol-induced increase in peroxidase. Cortisol had no effect on collagen breakdown and did not reverse the inhibition of collagen breakdown produced by oestradiol. It is postulated that the effects of oestradiol on peroxidase activity are mediated by uterine epithelial cells but that oestradiol effects on collagen breakdown may be mediated by another cell type.

Abstract Non-parametric survival analysis and piecewise exponential model (PEM) was used to estimate prevalence and incidence of goat mortality, to identify major clinical causes of morbidity and mortality related disease, and to investigate animal and environmental related risk factors affecting goat mortality at Ataye boer goat breeding and evaluation research site. A total of 671 kids and 347 adult (yearling) age goats were used for the analysis of non-parametric survival and piecewise exponential model for survival, mortality incidence rate and causes of morbidity and mortality analysis. The mortality incidence rate of kids and adult goats were 0.638 and 0.302 per animal year respectively. The 25th, 50th and 75th percentile of survival time of kids were 5, 157 and 1,274 days respectively and of adult goats were 280, 828 and 1,557 days respectively. The present mortality rate is relatively larger than reports of boer cross breeding and evaluation research sites in Ethiopia as well as goat mortality prevalence abroad. Gastro-intestinal related diseases, pneumonia, weak kid, agalactia, mismothering and hear water (cowdriosis) were most important causes of mortality. Constant piecewise exponential regression analysis of risk factors indicates that breed, kid birth weight (BWT), doe post-partum weight (PPWT), birth type, birth year and precipitation variables were associated with (p-value < 0.05) kid mortality rate. Pure boer kids compared with CHG cross boer goat, are 2.505 times at higher probability of mortality (p ≤ 0.001). A 1 kilo gram increase of kid birth weight and dam PPWT reduces mortality probability by 32.5% (p-value ≤ 0.001) and 6.4% (p-value ≤ 0.001) respectively. Twin birth kids are1.512 times higher rate of mortality (p-value = 0.001) compared with single born kids. A one-millilitre increment of 15 days average precipitation significantly reduces kid mortality by 7.8% (p-value ≤ 0.001). Fleshing of does during early meeting to improve the post-partum weight of does and kids is also important to reduce both kid and doe mortality at and after kidding. Immunization of new introduced and kids to common endemic diseases in the area, extensive control of ticks to breakdown heart water transmission and use of proper comfortable housing to reduce stress of goats is recommended. Improving nutrition particularly during scarce grazing and browsing feed availability is important to improving the health and reducing mortality of goats in intensively managed goat farms.

AbstractThe aim of the study was a comparative analysis of uterine horn diameter, calcium and magnesium concentrations in blood serum and uterine washings in cows both with and without endometritis. The study was performed on 28 cows at 5, 22 and 42 DP (day post partum), of which 14 cows had been diagnosed with endometritis and the other 14 had no endometritis. The animals were selected based on clinical symptoms and cytological examination. Uterine horn diameter was determined in both examined groups of cows using an ultrasonographic device. The level of calcium and magnesium in the blood serum and uterine washings, and protein in uterine washings was determined using a BS-160 Mindray analyzer. Uterus diameter was similar in both examined groups of cows only at 5 DP, and on subsequent days of examination this parameter was higher in the endometritis group compared to the control (P<0.001). Calcium levels in the blood serum of cows with endometritis were lower than in cows without endometritis, both at 22 DP (P<0.001) and at 42 DP (P=0.004). The levels of calcium, magnesium and total proteins in uterine washings were higher in cows with endometritis compared to the group without endometritis, both at 22 and at 42 DPP (P<0.001). The results of this study confirm that the process of uterine involution is slower in cows with endometritis compared to cows without endometritis, and the myometrium of inflamed uterus does not utilize sufficient amounts of calcium and magnesium, which means that the concentrations of these elements in uterine fluid are higher than in cows without endometritis.
