ThesisItem Open Access ULTRASONOGRAPHIC ASSESSMENT OF PLACENTAL THICKNESS IN DOGS AND ITS RELATIONSHIP WITH GESTATIONAL AGE(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2018-08) CHANDRASHEKHAR AYYA SALIMATH; Dr. G. SUDHAThe measurement of gestational sac diameter (GSD) and biparietal diameter (BPD) using ultrasonography (USG) remained fairly accurate determinants of gestational age (GA) in canines during early and later stages of gestation with precision of ±1 to ± 2 days. The present study looked at the possibility of placental thickness (PT) as a determinant of GA using USG in normal pregnancies of different breeds and body sizes and then to correlate the same with reported gestational age (RGA). A cross sectional observational study was conducted on 90 pregnant dogs of different breeds and parity and a total of 112 observations were made by using ALOKA PRO SOUND α-6 ultra sound unit using 5 MHz convex probe.ThesisItem Open Access CLINICAL EFFICACY OF MIFEPRISTONE AND MISOPROSTOL IN INDUCTION OF PARTURITION IN FEMALE DOGS WITH SINGLE PUPPY SYNDROME(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR- 585 401, 2018-02) VIJAY PEETALA; Dr. V. CHANDRASHEKHARA MURTHYA clinical study was designed to evaluate the efficacy of mifepristone and misoprostol in induction of parturition in dogs with single puppy syndrome. The incidence of single puppy syndrome was 5.08 per cent, recorded in nine different breeds of dogs. The highest incidence was observed in Pug while the lowest in Dachshund and Chihuahua. Further, higher incidence was noticed in primiparous bitches with less than two years of age. The incidence of dystocia due to single puppy syndrome was 25 per cent. The blood glucose, serum calcium and phosphorus concentrations were within normal physiological range in both control and treatment groups. In control group, all the animals bearing singleton were presented with dystocia and assisted whelping was performed. All the animals in treatment group hadn’t shown any signs of parturition even after 62 days of gestation were administered mifepristone @ 5 mg/kg BW per orally twice a day at 12 hours interval followed by intra vaginal administration of misoprostol @ 200 µg for bitches with ≤ 20 kg BW and 400 µg for bitches with > 20 kg BW, 12 hours after second dose of mifepristone. The mean time taken for the expulsion of the single pup from the time of initiation of treatment was 28 ± 2.74 hours and the mean time taken for the expulsion of the single pup after administering misoprostol intravaginally was 5.3 ± 1.7 hours. Live singletons were whelped in all treatment group animals giving 100 per cent results. It is concluded that the use of mifepristone and misoprostol combination is safe and effective for induction of parturition in female dogs with single puppy syndromeThesisItem Open Access CLINICAL STUDIES ON PSEUDOPREGNANCY IN DOGS(KARNATAKA VETERINARY, ANIMAL AND FISCHERIES SCIENCE UNIVERSITY, BIDAR, 2018-08) SHILPA V. S.; Dr. V. CHANDRASHEKHARA MURTHYA study on the prevalence, predisposing factors, clinical signs associated with pseudopregnancy and efficiency of dopamine agonists and management practices to reduce the clinical manifestation of pseudopregnancy was conducted. The prevalence of pseudopregnancy was 35.41% with highest prevalence in medium breeds and lowest in small breeds. The prevalence was higher in young (less than 2 years) and nulliparous female dogs. Age and parity showed a statistically significant influence on the exhibition of pseudopregnancy. The signs were exhibited during the anestrus stage of estrous cycle in majority of dogs as indicated by the serum progesterone values less than 1 ng/ml. The average number of days from last estrus was 63±2.25 days. The clinical signs varied widely between individuals and mammary development with milk or milk like secretion was the most common sign (96.08%). Physical changes and maternal instincts were also recorded and clinical signs were seen in less than 50% of the dogs. The complications like mastitis or mammary dermatitis were rare (3.96%). Cabergoline at 5µg/Kg BW once daily took an average of 6.4±0.65 days for complete recovery and bromocriptine at 10µg/Kg BW twice daily took an average of 9.5±0.73 days. Managemental practices like food and water withdrawal during night hours and application of Elizabethan collars for an average of 15±0.77 days also had a significant effect in reducing clinical signs compared to control group. Even though pseudopregnancy is a self-limiting condition, when clinical signs are exacerbated, compared to bromocriptine, cabergoline was found to be safe and effective. Managemental interventions were found to be effective in absence of veterinary aid.ThesisItem Open Access ULTRASONOGRAPHIC ASSESSMENT OF PLACENTAL THICKNESS IN DOGS AND ITS RELATIONSHIP WITH GESTATIONAL AGE(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2018-08) CHANDRASHEKHAR AYYA SALIMATH; Dr. G. SUDHAThe measurement of gestational sac diameter (GSD) and biparietal diameter (BPD) using ultrasonography (USG) remained fairly accurate determinants of gestational age (GA) in canines during early and later stages of gestation with precision of ±1 to ± 2 days. The present study looked at the possibility of placental thickness (PT) as a determinant of GA using USG in normal pregnancies of different breeds and body sizes and then to correlate the same with reported gestational age (RGA). A cross sectional observational study was conducted on 90 pregnant dogs of different breeds and parity and a total of 112 observations were made by using ALOKA PRO SOUND α-6 ultra sound unit using 5 MHz convex probe. The dogs were categorised into two groups, namely the large breeds and small breeds, GA and PT were recorded from 3rd to 4th week of gestation. The mean PT in small breeds of dogs was found to be 3.42 ± 0.32, 4.20 ± 0.15 and 4.36 ± 0.12 at 36.11 ± 1.19, 46.11 ± 0.71 and 54.84 ± 0.89 average GA, respectively with a significant positive correlation between PT vs GA and PT vs RGA (r= 0.58 and 0.59), and respective R² of 0.34 and 0.35 was recorded. Similarly, for large breeds mean PT of 2.91 ± 0.24, 5.28 ± 0.15 and 5.88 ± 0.13 at 33.80 ± 0.81, 44.92 ± 0.66 and 57.18 ± 0.98 days, respectively with significant positive correlation between PT vs GA and PT vs RGA (r=0.82,0.81) and respective R² of 0.67 and 0.67 was recorded. The present study revealed that there was no significant difference between the calculated gestational age (CGA) and reported gestational age (RGA). It was concluded that the placental thickness (PT) was significantly correlated with GA and RGA and it can be used to estimate gestational age of foetus along with other parameters like GSD and BPD.ThesisItem Open Access COMPARATIVE PREGNANCY DIAGNOSTIC TECHNIQUES IN GOATS(KARNATAKA VETERINARY ANIMAL AND FISHERIES SCIENCE'SUNIVERSITY, BIDAR-585226, 2018-10) SHASHIDHAR; Prof. M. K. TANDLE; Dr. M. D. SURANAGI; Dr. R. G. BIJURKAR; SRIKANT KULKARNIThe study was undertaken with the objective to compare different techniques of pregnancy diagnosis like pregnancy detector, vaginal electrical resistance (VER), ultrasonography and progesterone assay in Osmanabadi goats. Pregnancy detector has not yielded good results to detect pregnancy in does from day 1-30 post breeding. Higher VER values are indicative to detect pregnancy on day 19 post breeding and with accuracy of 66.67 % and 100 % from day 19-20 and day 21-30 post breeding respectively in does. Trans-abdominal ultrasonography was effective tool to detect pregnancy with accuracy of 73.33 %, 80.00 % and 100 % from day 19-20, 21-30 and 31-45 post service respectively in does. Visibility of embryonic vesicle and gestational sac as early as on day 20 after natural service in does by trans-abdominal ultrasonography was an accurate, rapid, non invasive, potential and safe technique for pregnancy diagnosis in does. Visibility of gestational sac and fetal heart beat was detected on day 30 by trans-abdominal ultrasonography and fetal heart beat and measurement of crown-rump length and biparietal diameter measurement was possible on day 45 post breeding in does. Progesterone estimation was useful aid to detect pregnancy in does with highest accuracy (100.00%) from day 21-30 followed by day 19-20 (80.00 %) and day 1-18 (66.67 %) respectively. Progesterone estimation on day 18 post breeding was a useful aid to detect pregnancy in does. Progesterone estimation was effective aid to detect pregnancy from day 1-18 post breeding in does with 81.82 % sensitivity, 25.00 % specificity and 66.67 % accuracy respectively.ThesisItem Open Access EFFICACY OF GnRH TREATMENT IN REPEAT BREEDER CATTLE(KARNATAKA VETERINARY ANIMAL AND FISHERIES SCIENCE'SUNIVERSITY, BIDAR-585226, 2018-09) SATISH BIRADAR; R.B. DHABALE; M.K. TANDLE; S.M. KARTIKESH; SRIKANT KULKARNIEfficacy of GnRH analogue (Buserelin acetate) treatment on the day of AI, 12th day post AI or on both, the day of AI and 12th day post AI, on repeat breeder cattle was analysed in 32 repeat breeder cattle. Animals were divided into four groups of 08 animals each viz., group-I treated with 2.5mL(10mcg) GnRH analogue on the day of AI, group-II treated with GnRH on 12th day post AI, group-III treated with GnRH both on day of AI and 12th day post AI and group-IV were inseminated without treatment as a control group. They were inseminated and blood sample was collected for analyzing progesterone and alkaline phosphatase enzyme on the day of AI, 12, 20 and 40th day post AI. There was a significant (P<0.05) increase in the progesterone concentration in animals receiving GnRH treatment than control and AKP concentration increased significantly (P<0.05) in pregnant animals. The conception rates of each group was 75%, 37.5%, 62.5% and 37.5% for group-I, II, III and IV respectively. The study concluded that single dose of GnRH at the time of AI was most efficient treatment for repeat breeder cattleThesisItem Open Access SUPPLEMENTATION OF OLIVE AND ALMOND OIL IN EXTENDERS FOR PRESERVATION OF SEMEN IN NARI SUWARNA STRAIN OF SHEEP(KARNATAKA VETERINARY ANIMAL AND FISHERIES SCIENCE'SUNIVERSITY, BIDAR-585226, 2018-07) NANCY JASROTIA; Prof. M. K. TANDLE; Dr. M. D. SURANAGI; Dr. R. G. BIJURKAR; Dr. SRIKANT KULKARNIThe study was carried out to evaluate the effect of supplementation of almond oil (AO) and olive oil (OO) in Skim milk (SM) and Tris egg yolk (TEY) extenders, on sperm quality parameters of the NARI Suwarna ram semen refrigerated for 72 h. Semen collected from five mature NARI Suwarna rams was pooled and diluted to a final concentration of 0.8 x 109 spermatozoa/ml in SM and TEY extenders supplemented with AO and OO at 0.25% v/v (SM, SMAO, SMOO, TEY, TEYAO, TEYOO). Semen was then stored at 5°C and several sperm motility and velocity parameters were assessed by Computer assisted semen analysis (CASA) at 0, 24, 48 and 72h of storage. Randomized Block Design (RBD) was used to test the significant difference between extenders. Extenders of TEY (TEY, TEYAO and TEYOO) were significantly (P<0.05) better as compared to SM, SMAO and SMOO. Supplemented skim milk extenders (SMAO and SMOO) preserved motility and velocity parameters better compared to plain SM extender. Addition of olive oil (0.25%) in TEY extender had beneficial effect in preserving rapid progressive sperm motility percentage better than in other extenders and sperm curvilinear velocity (VCL) improved after addition of almond oil and olive oil in TEY extender. Assessment of sperm motility and velocity parameters by CASA revealed TEY as better extender for preservation of refrigerated NARI Suwarna ram semen for 72 h.ThesisItem Open Access EFFECT OF FLUSHING AND ESTRUS SYNCHRONIZATION IN KENGURI EWES(KARNATAKA VETERINARY ANIMAL AND FISHERIES SCIENCE'SUNIVERSITY, BIDAR-585226, 2018-09) NAGARAJ; Dr. R G. BIJURKAR; Dr. M.K. TANDLE; Prof. R.B. DHABALE; Dr. SHRIKANT KULKARNIThe study was conducted to know the efficacy of different synchronization protocols and effect of flushing in postpartum anestrous Kenguri ewes in non-breeding season. Thirty healthy ewes of 60 days postpartum were selected and divided in to 5 groups, each containing 6 animals (n=6). All the five groups were fed with maize grains (250 gm/ewe/day) for 15 days prior to synchronization protocol. G I served as control group with only flushing without treatments. After 15 days of flushing, 4 treatment groups received CIDR intravaginal device (0.3 gm of progesterone) and left intravaginal for 12 days. After 12 days, during the removal of CIDR, G II and G IV animals received I/M inj. PGF2α @125µg /ewe whereas G III and G V received I/M inj. PMSG @ 500 IU/ewe. Upon exhibition of estrus and natural mating, G IV and G V animals received I/M inj. hCG @500 IU/ewe. Estrus response (%) was 33.33, 33.33, 66.66, 50.00 and 66.66 and conception rate (%) was 50.00, 50.00, 50.00, 66.66 and 75.00 in GI, GII, GIII, GIV and GV respectively. Mean ± SE values of onset of estrus was 204.00 ± 12.00, 61.83 ± 3.17, 44.25 ± 1.00, 62.53 ± 1.85 and 45.15 ± 1.34 h and duration of estrus was 24.88 ± 0.88, 30.54 ± 0.79, 37.12 ± 0.58, 29.03 ± 1.07 and 35.39 ± 1.17 in G I, G II, G III, G IV and G V respectively. In conclusion, hCG treated animals had better conception rate in postpartum anestrous Kenguri ewes.ThesisItem Open Access EFFECT OF FLUSHING AND ESTRUS SYNCHRONIZATION IN POST PARTUM ANESTROUS GOATS(KARNATAKA VETERINARY ANIMAL AND FISHERIES SCIENCE'SUNIVERSITY, BIDAR-585226, 2018-09) DEEKSHITH, T.; Dr. R G. BIJURKAR; Prof. M. K. TANDLE; Prof. R.B. DHABALEThe study was conducted to find out the effect of flushing and hormonal effects upon induction and synchronization of postpartum anoestrus goats in and around Bidar. Thirty does which were about 60 days postpartum were selected and divided in to 5 groups (n=6). All the 5 groups were fed with maize grains (250 gm/doe/day) for 15 days. Group one served as control with only flushing. After 15 days of flushing, 4 treatment groups received CIDR intravaginal device containing Progesterone 0.3gm and left intravaginally for 14 days. At the removal of CIDR after 14 days of treatment, G2 and G4 animals received I/M inj of PGF2α @125µg/doe whereas G3 and G5 received I/M inj of PMSG @ 500IU/doe. Upon exhibition of estrus, 4th and 5th group animals received I/M inj of hCG @ 500IU/doe after natural mating. Estrus inductions were recorded for G1, G2, G3, G4 and G5 as 66.66, 50.00, 83.33, 50.00 and 83.33 % respectively. Conception rate were recorded for G1, G2, G3, G4 and G5 as 100, 33.33, 60, 66.66 and 80 % respectively. Mean ± SE values of onset of estrus were recorded for G1, G2, G3, G4 and G5 as 139.75±19.02, 68.5±4.80, 33.2±2.22, 70.0±1.85 and 32.0±2.82 Hr respectively. Mean ± SE values of duration of estrus were recorded for G1, G2, G3, G4 and G5 as 30.25±1.854, 33.16±2.24, 47.7±2.095, 31.0±0.577 and 36.3±0.86 Hr respectively. Serum was estimated for serum glucose, cholesterol and progesterone. It was concluded that the control group (G1) which received only flushing and group receiving Flushing+ PMSG+ hCG (G5), both have high efficiency in increasing conception rate in postpartum anestrous goats.
