Ovarian Dynamics

The objective was to determine the size of the dominant ovulatory follicle, the ovulation time and the conception rate of cows in anestrus treated with serum equine chorionic gonadotropin (eCG), recombinant chorionic gonadotropin and untreated controls. 57 anestrus primiparous Brangus cows were used with 70 ± 26 days of calving and a body condition of 2.50 ± 0.15. They were synchronized with a FTAI protocol based on estrogen and progesterone devices (DI). Upon removal of DI, 3 groups were made according to the type of eCG applied: serum eCG received 400 IU im of equine Chorionic Gonadotropin, recombinant eCG received 140 IU of recombinant Equine Chorionic Gonadotrophin and Control did without treatment. Follicular size and time of ovulation (normal or abnormal) was determined at DI removal, during FTAI and 7 days later. An ANOVA was performed to determine the effect of the treatment on ovarian dynamics and a chi-square test and correspondence analysis to establish associations. In normal ovulation cows at the FTAI, 94.4% of the serum eCG, 55.5% of the recombinant eCG and 71.4% of the Control cows presented a dominant ovulatory follicle (DOF), which in those treated with serum eCG, it was 1.4 mm greater in relation to the Control (P = 0.0073). The ovulation rate, in normal and abnormal ovulation cows, was 94.4% for serum eCG, and for recombinant eCG and 66.6% for Controls. A significant association was detected between ovulation time and the treated groups (P = 0.0042). Normal ovulation was 38.9% higher in cows with serum eCG in relation to those treated with recombinant eCG and 50.8% in comparison with Control. A significant relationship was observed between the conception rate and the groups treated with the different Gonadotropins (P = 0.0574), being 66.7% in serum eCG, 50% in recombinant eCG and 28.6% in the Control. The use of eCG, either serum or recombinant, in anestrus primiparous cows, stimulates the development of DOF at FTAI, increases ovulation rate and improves conception in relation to untreated cows.

Objective: To evaluate the effectiveness of placing a resorbable collagen barrier in impeding the extrusion of obturation material in primary molars undergoing resorption. Study design: All the 94 canals in 47 mandibular molars were allocated to 2 groups- Group ‘A’- 47 canals with collagen barrier (Test group) and Group ‘B’- 47 canals without collagen barrier (Control group) based on randomization protocol. Pulpectomy was performed and obturation of both test and control canals were radiographically assessed. Pearson’s chi – square test was applied to analyze the results. The significance level was predetermined at p < 0.05. Results: Among the test group, 93.6% of the canals showed no extrusion while, 6.4% showed visible extrusion of the material outside the apex. In the control group, 83% showed no extrusion whereas 17% of the canals showed visible extrusion outside the apex. But no significant difference was noted (p>0.05). Conclusion: The placement of resorbable collagen barrier in the apical third of the canal prevented the extrusion of obturating material beyond the apex in resorbing primary molars.

The objective of this study was to determine leucocyte and offspring production of guinea pig (Cavia cobaya) giving Anredera cordifolia leaf extract. Materials used were female 16 heads of guinea pig with body weight of 425g. The treatments were an extract of A. cordifolia leaf at doses of 0, 10, 50 and 90 mg/head, designated as T0, T1, T2 and T3, respectively. A. cordifolia leaf extract was administered orally from 10 days prepartum to 10 days postpartum. Blood was taken at 10 days prepartum and 10 days postpartum. Total birth of the offspring was observed. Data were analyzed by analysis of variance and if there was effect of treatment, then continued with Duncan multiple range test and Chi-Square test for fetal production between the given A. cordifolia leaf extract and control. The result showed that there was no significant difference for 10 days prepartum after addition of A cordifolia leaf extract treatment. The postpartum treated showed a total 50 mg/head level increaed for monocytes than that of level 0, 10 and 90 mg/head. Ten days postpartum treatment showed the total increase for leucocyte and monocytes total were 50 and 90 mg/head, respectively compared to 10 mg/head level. Total lymphocyte of 90 mg/head increased compared to level 10 and 50 mg/head. The highest total neutrophil as found at level of 50 mg/head which increased compared to the level of 0 and 10 mg/head. ProvisioningA. cordifolialeaf extract at doses level of 50 and 90 mg/head could increase litter size (P<0.05; χ2=9.267) and decreased offspring mortality (P<0.05; χ2=6.4). In conclusion, by giving 50 mg/head A. cordifolia leaf extract could increase leucocyte profile and offspring production of guinea pig.

A cross sectional study was conducted in Eastern and Western parts of Chitwan district from November 2015 to April, 2016  in two parts, the social study followed by biological to determine and compare the prevalence, distribution of antibodies, and level of awareness of farmers  against Brucella abortus in cattle of the two regions of same district. Altogether blood samples of 92 cattle were taken for detection of Brucella antibodies by using RBPT test and the positive samples were further retested by Indirect ELISA test through ID Vet iELISA kit 2016. The samples which showed positive on both tests were confirmed as seropositive. Chi -square test and Fisher Exact test was used to find out the association between various variables. The result showed that 14.13% (13/92) and 10.86% (10/92) sample were positive by RBPT and iELISA test respectively. There was no significant prevalence differences (p>0.05) on location, age group, breed type, and method of service (artificial and natural) used in cattle. Comparing abortion with prevalence of Brucellosis, there was significant differences (p<0.05) in the result of both RBPT and iELISA test. Inferring from this result, there is association between the abortion and occurrence of Brucellosis. The higher significant prevalence differences (p<0.01) was according to the time of abortion where higher seropositivity was obtained in the cattle aborted on 5-7th month of pregnancy and cattle of 3rd parity. The study showed the existence of Brucellosis in Chitwan district with no adoption of any preventive measures against this disease, so here is current need of the strategies for its prevention and control in order to mitigate such overwhelming situation.Int J Appl Sci Biotechnol, Vol 4(3): 365-371

The aim of this study was to enhance ovarian follicular development and subsequent oocyte retrieval by the use of a combined equine chorionic gonadotropin (eCG) and recombinant bovine somatotropin (rbST) protocol, as well as to compare its efficiency between the Brazilian zebu breed Tabapua (TAB) and Holstein (HOL) nulliparous heifers. In a changeover design, TAB (n = 16) and HOL (n = 12) were allocated to 1 of 2 protocols in 2 distinct periods. Two days before initiation of the protocols (D2), dominant follicles were ablated by transvaginal ultrasound-guided aspiration: Group 1: on day 0 (D0) a subcutaneous injection of 500 mg of rbST (Boostin®, Intervet, SP) and on D2 an intramuscular injection of 500 IU of eCG (Novormon®, Schering-Plough-Intervet, SP); and control: vehicle only. Two days later (D4), ovum pickup (OPU) was performed and the ovarian follicle population was evaluated by ultrasound. Twenty days after the first OPU session, heifers were switched over across treatments and were aspirated a second time, so that a total of 28 sessions were performed for each treatment. Main effects of period, breed, and protocol and their interactions on follicle numbers and oocyte yield were analysed through the GENMOD procedure of SAS (SAS®, Cary, NC, USA) using the Poisson distribution option. Means were compared by orthogonal contrasts, and the probability value set at 0.05 for significance unless otherwise specified. There was an interaction effect between hormonal stimulation and breed (P < 0.05) on the number of aspirated follicles (2 to 10 mm in diameter) such that they were higher in TAB treated (41.4 ± 2.6) compared with control (29.9 ± 2.6) heifers and did not differ between the HOL heifers (15.5 ± 2.6 v. 14.4 ± 2.6 in treated and control heifers, respectively). Overall, follicle numbers were higher (P < 0.0001) in TAB (35.6 ± 1.84) than in HOL (15.0 ± 2.1) heifers and in treated (28.4 ± 2.0) v. control (22.1 ± 2.0) heifers (P < 0.001). There was no effect (P = 0.77) of treatment on total viable oocytes (grades 1 to 3) between treated (3.5 ± 1.2) and control (3.9 ± 1.1) heifers. Tabapuã heifers had more (P < 0.05) viable oocytes than HOL (5.9 ± 0.9 v. 1.6 ± 1.4). In conclusion, the proposed protocol may improve OPU results but viable oocyte yield was not associated to the higher number of follicles available for aspiration. It may be necessary to modify this protocol to improve results perhaps by increasing the time window between rbST and eCG injections as well as by increasing the rbST dosage for heifers. The present protocol may be cost saving, compared with follicle stimulating hormone, for initial OPU sessions in the case of Tabapuã heifers because it is expected that responses decrease after a sequence of eCG injections. It is also interesting to notice that it is possible that HOL heifers already have higher endogenous growth hormone concentrations, which could help to explain the interactive effect observed in the ovarian response. Further studies are necessary to improve this protocol especially in HOL heifers. CNPQ, CAPES, Schering-Plough-Intervet.

In recent years, reproductive performance of dairy cows has been declining worldwide, especially among cows of high genetic merit for milk production. The cause of the low fertility may considerably vary across countries and is probably multifactorial. This problem remains unsolved. Further, the first-service conception rate of dairy cows has remarkably decreased worldwide. The number of services required for conception has increased due to the low fertility in dairy cows. However, there are few reports about the relationship between conception rates and the number of services in the current dairy cows. The objective of this study was to investigate whether the number of services affects the conception rates of dairy cows. Data concerning the conception rates was obtained for 8386 Holstein cows from 40 commercial dairy herds in eastern Hokkaido, Japan, from 2006 to 2009. The diagnosis of pregnancy was confirmed by rectal palpation between 30 and 45 days after insemination. The average interval between calving and the first-service was 87.3 days. The average milk yield was 8500 kg. Number of conducting services was from the first to the seventh service. The conception rate was analysed using chi-square test. The results are presented in Table1. The conception rate from the first to the seventh service was 40.2 to 54.0%. The conception rate at the first service was significantly low (40.2%); however, the conception rates did not significantly differ after the second-service. A similar tendency was observed during each year. Moreover, the total percentage of conceptions from the first to the third service was 83.8%. The average number of services per conception was 2.2. The results of this study indicate that the first service yielded the lowest conception rates. The conception rates after the second service did not significantly differ. Moreover, ∼84% of the dairy cows became pregnant between the first service and the third service. However, this result shows that ∼16% of the dairy cows in the herds were repeat breeding. In order to improve fertility, it is necessary to study the factors that affect the first-service conception rates of dairy cows. Moreover, to improve the conception rate of dairy cows, it is important to elucidate the cause of these problems.

Atopic dermatitis (AD) is a chronic, relapsing, highly pruritic skin condition that develops in early childhood. Sleep problems are common in AD children and lead to impaired quality of life, disturbance of neurocognitive function and behavior. The aim of this study was to assess the prevalence of sleep problems in 0-36 months old Indonesian children with AD. Children aged 0-36 months were enrolled, divided into two groups, AD and control. Sleep problems and AD were assessed using Brief Infant Sleep Questionnaire (BISQ) and Severity Scoring of Atopic Dermatitis Index (SCORAD). Chi-square test was performed to compare the outcome. There were 35 children participating in each group. In children with sleep problems, 85.7% were diagnosed with AD and 11.4% were non-AD. Nocturnal sleep duration, night waking, nocturnal wakefulness, sleep onset time, method of falling asleep and parental consideration of sleep problems occur more often within AD group. Severity of AD also significantly contributes to sleep problems in AD group. In conclusion, this study showed that sleep problems are more prevalent in children with AD.

SummaryObjective: The aim of this study was to monitor the ovarian response and conception rate following estrous synchronization using CIDR, Ovsynch and double prostaglandin F2α protocols in Egyptian buffalo heifers. Material and methods: A total of 80 cyclic buffalo heifers were divided into four equal groups: CIDR (intravaginal progesterone releasing device, EAZI-BREEDTM CIDR®), Ovsynch (GnRH, PGF2α, GnRH injections), PGF (double PGF2α doses) and control. Timed artificial insemination (TAI) was performed in all heifers. All animals were exa - mined using ultrasound and blood samples were collected for measurement of progesterone. Results: A new follicular wave occurred earlier in the Ovsynch and PGF groups than in the CIDR group (p < 0.05). The mean diameter of the ovulatory follicle was smaller in the CIDR group than in the Ovsynch and PGF groups (p < 0.05). The ovulation rate was 100% in the CIDR group, 75% in the Ovsynch group and 70% in the PGF group. In the control group a lower pregnancy rate (20%) was determined in than in the CIDR (35%), Ovsynch (40%) and PGF (35%) groups. Progesterone concentrations were numerically higher in pregnant heifers of the CIDR group but the difference was non-significantly compared to the Ovsynch, PGF and control groups (p > 0.05). Conclusion and clinical relevance: EAZIBREEDTM CIDR®, Ovsynch-based TAI and PGF protocols were effective in synchronizing oestrus and resulted in nearly similar pregnancy rates in Egyptian buffalo heifers.

Drosophila, as the test organism, was used to assess 17 chemicals. The teratogenic potential of 15 of these chemicals is well established from animal studies or human epidemiology. The test involves examination of adult flies following treatment during larval stages of development. Flies are examined for abnormal external morphology. The incidence of abnormalities in treated and control populations is compared using the Chi-square test. All 17 chemicals were active to varying degrees in the test system. Most chemicals produced a unique response yielding individual patterns of abnormalities. These results suggest that Drosophila may have the potential to become a valuable teratogen screen, but further, more rigorous examination–particularly with nonteratogens–is required.
