Effect of intrauterine concentrated lugol's solution during the early postpartum period on subsequent fertility in dairy cows

The effect of concentrated Lugol's idoine solution on some reproductive traits was studied in hundred and twenty three dairy cows. The cows were randomly assigned into one of two treatment groups. The 1st group [n=63] was infused intrauterine with 100-200 ml [4%] lugol's iodine solution at 12-14, days postpartum. The second group [n=60] received intrauterine saline solution [100-200 ml] and served as control. The mean interval from calving to uterine involution, first estrus, days open, number of services percenception and total conception rate were significantly improved when compared with the control one

Chemical castration in male rats with special reference to the micromorphological features of the sex organs

Sixty 6-month old male rats were classified into 15 groups and were intratesticularly injected with some necrotizing chemical agents including 3% and 5% formalin, different grades of glacial acetic acid either alone or with glycerol, alcohol 95% and 30% calcium chloride in 95% alcohol. At the end of the experiment, testes, epididymides, seminal vesicles and prostate gl and s were excised and histological sections were prepared. The results showed that the most effective irreversible degenerative changes in the testes and accessory gl and s were induced by 3% and 5% formalin, the different grades of glacial acetic acid and 30% calcium chloride in 95% alcohol. The clinicopathological results were assessed and thoroughly discussed with the other previous similar articles

Plasma B-endorphin in buffaloes and cows with and without retained placenta

This study was conducted on 14 and 12 pluriparous buffaloes and cows respectively, seven of the buffaloes and six of the cows had retained placenta. Blood samples were collected from all animals in heparinized vacutainer tubes and cooled on ice, plasma was removed by centrifugation in a cooling centrifuge and freezed at -20 until assayed for B-endorpfcin. Statistical analysis revealed significantly [P < 0.02] higher plasma levels of B-endorphin in both buffaloes [1045.417 +/- 148.156 Pg/ml] and cows. [969.666 +/- 140.064 Pg/ml] with retained placenta than in buffaloes [74.246 +/- 8.772] and cows [95.00 +/- 12.02l] without retained placenta. It is suggested that, B-endorphin would be considered as a factor which probably influences the retention of placenta in farm animals

Comparison of using gonadotropin releasing hormone [Gn-RH] and/or manual rupture in treatment of ovarian cysts in dairy cows

This study was designed to evaluate the efficiency of the treatment with Gn-RH and /or manual rupture of the ovarian cysts. The work was carried out on 30 Friesian and Crossbred cows having postpartum ovarian cysts classified into four groups. Group I [6 cows] left without treatment and served as control, the cows in group II [8 cows] were treated i.m. with 20 ug Gn-RH [Receptal, Hoechst, AG], the cows in group III [6 cows were treated by manual rupture of the cyst and the group IV [10 cows] were treated i.m. with Gn-RH [20 ug] with a simultaneous crushing of the cysts. The animals were closely observed for estrus, and two or three months following treatment, the cows were reexamined for pregnancy diagnosis. Animals treated with Gn-RH together with crushing of ovarian cysts exhibited percentage of heat appearance [90%] within a period of 12.11 +/- 4.79 days following treatment and also 90% got pregnant. In cows treated only with Gn-RH, 87.5% came in heat after 17.18 +/- 6.08 days and 75% become pregnant. In cows treated by manual rupture of the cysts, 66.6% exhibited heat within 32.0 +/- 11.51 days and 50% conceived

Prophylactic treatment with administration of Selenium and combination of Selenium and Vitamin E for placental retention and postpartum reproductive efficacy in dairy cows

Sixty Friesian and crossbred cows were used to determine the effects of treatment with selenium with or without vitamin E on retained placenta [RP] and some reproductive parameters. At about 30 days before estimated calving date, 20 cows were injected i.m. with 10 mg selenium and 500 mg vitamin E and other 20 cows were injected with 50 mg selenium alone. Twenty uninjected cows served as controls. Treatment had significant effects on retention of placenta, selenium and vitamin E [2/20, 10%] was more effective in preventing placental retention than did selenium injection alone [5/20, 25%] and control ones [10/20, 50%]. Additionally, treatment had significant effects on days to conception [77.0 +/- 2.5, 92.9 +/- 2.7 vs 106.7 +/- 2.5] and conception rate [90%, 65% vs 45%] in selenium and vitamin E, selenium-treated cows and control ones, respectively. Interestingly, the incidence of newborn mortality was 10% in both selenium and vitamin E and selenium alone, whereas, it was 30% in control group. In feeds selenium concentrations in concentrate and green grass [Darawa] were 0.013 ug/g and 0.26 ug/g, respectively

Serum total protein and protein electrophoretic pattern of buffalo fetus during development

Changes in serum total protein and protein fractionation of buffalo fetus were studied from 5[th] to 10[th] months of gestational age. The total protein concentration increased progressively with a prominent increase in albumin near term. The data obtained revealed five serum peotein fractions in buffalo fetus. These fractions were prealbumin, albumin, alphafeto-protein, transferring and gamma globulin. The gamma globulin started to apprar in the fetal serum at 6[th] month of gestational age
