    Role of Hormones in Reproduction Management of Swine
    (Birsa Agricultural University, Ranchi, 1996) Shishir Kumar Harichandanray; Dr. A. K. Sinha
    1.Synchronized farrowing during day time on working days was possible either through intramuscular route (PG 5 mg) or IVSM route with a considerable low (1mg) dose of PG. 11. Termination of pregnancy with PG (day 111) revealed no adverse effect on piglet size or weight at birth. 111. Induced farrowed sows recorded significantly shorter weaning to fertile estrus interval. iv. Addition of oxytocin or EV to PG (5 mg) resulted in more precise farrowing (LWY) by shortening induction interval. V. Post parturient PG treatment (LWY) significantly increased piglet survivability and weight gain. Significantly shorter weaning to fertile estrus interval was recorded in the treated pigs. vi. The piglet born out of PG treated mother weaned at day 40, 45 or 50 consistently showed higher body weight than control. Vii .Application of PMSG (500 IU) alone or in combination with HCG (500 IU) at 24 hrs of weaning resulted in a significantly earlier post weaning estrus with higher CR than control. viii. Administration of HCG to sows at day 12 of service had a significant increase on piglet weight at birth.

    Freezing of Buck Semen with Different Cry protective Agents Leakage of Enzymes and Fertility Trial
    (Birsa Agricultural University, Ranchi, 1992) Murari Prasad Singh; Dr. B. K. Singh
    1.Semen of Beetal bucks appeared more cryoresistant and therefore, can be frozen more successfully than either crossbred or Black Bengal bucks. 2.Lactose glycerol appeared to give better cryoprotection to spermatozoa than either glycerol alone or glycerol + DMSO. 3. DMSO alone appeared to be a poor cryoprotectant. 4. Cryoprotection offered by lactose appeared to be concentration dependent; higher the concentration better was the protection. 5. Quantitation of AKP, LDH and aminotransferases (AST and ALT) can serve as good marker for spera quality during freezing ability of a semen sample. 6.Results on fertility trials were not conclusive. This requires further studies on larger population.

    Studies on Liquid Preservation and Potential Fertility of Boar Semen
    (Birsa Agricultural University, Ranchi, 1993) Ram Pravesh Pandey; Dr. B. K. Singh
    1. Kiev dilutor proved to be the most suitable extender for preservation of boar semen at 15 - 20°c. 2. Both Kiev and BTS dilutors maintained acrosome integrity, sperm motility and live sperm percentage more effectively as compared to BL-1 up to 72 hours of preservation. 3. Gentamycin was most effective against both Gram +ve and Gram -ve bacterial genera, isolated from boar ejaculates 4. Penicillin and streptomycin which are commonly added to boar semen extender were observed to be least effective against Gram +ve and Gram -ve bacteria. 5. Quantitative estimation of transaminases, lact dehydrogenase and alkaline phosphatase can serve as perfect indicator for assessing sperm quality during preservation. 6. Preservation time and extenders used for diluting boar semen had no effect on litter size. 7. Artificial insemination in pigs gave 69.11 per cent farowing rate with freshly diluted semen and 61.62, 53.02 and 51.28 per cent respectively after 24, 48 and 72 hours of preservation.

    Studies on the Role of Motility Enhancing Agents on Freezing Seminal Attributes and Fertility of Buck Semen
    (Birsa Agricultural University, Ranchi, 1992) Manoranjan Prasad Singh; Dr. B. K. Singh
    Addition of 2 mm caffeine and 5 ml of glutathione and 5 mm of theophylline increased the progressive motility as well as fertility rate of frozen thawed semen over the controls. 2 mm caffeine treated dilutor appeared to be the best followed by TT5 and TG5 dilutors in all the three breeds. Enzyme leakage was also less in TC2, TC5 and TT5 diluted semen samples.

    Studies on Some Aspects of Reproduction in Different Breeds of Pigs and Relationship between Reproductive performance and Blood Biochemical Profile
    (Birsa Agricultural University, Ranchi, 1987) Birendra Kumar Singh; Dr. B. K. Singh
    The present investigation was conducted to compare the reproductive performance of three breeds of pigs viz. Large white Yorkshire, Landrance and Hampshire during three seasons. The relationship between reproductive efficiency and blood biochemical profile during different stages of reproduction was also studied. Furthermore, the changes in vaginal epithelium during different stages of oestrous cycle and pregnancy were observed using biopsy technique. 1. The average age at puberty in large white Yorkshire landrace and Hampshire was noted as 320.54, 1.95, 314.68, 1.62 and 316.52, 1.56 days. The influence of breed on attainment of puberty was significant (P-0.05). The influence of season on puberty attainment was also significant(p0.01) and gilts born during rainy season attained puberty earlier as compared to gilts born during winter and summer season. 2. The mean duration of oestrous cycle and average duration of oestrus did not differ significantly between breeds during different seasons. A significantly (p-0.01) higher occurrence of oestrus was recorded during winter (42.06 +0.47%) than summer (24.16=0.51) and rainy season (33.10 +0.49). 3. The mean duration of 1st, 2nd and 3rd stage of farrowing was 2.49 -.18, 2.27+.162 and 2.31 + 0.19 hours respectively. The total duration of farrowing was 5.46 +.628, 8.95 +.74 and 6.87 +.60 hours in large white Yorkshire, landrace and Hampshire respectively and the differences were statistically significant (P 0.01). The overall placental weight was 1.25 +0.54 Kg.

    Observation on Parturition in Goats
    (Birsa Agricultural University, Ranchi, 1981) Ram Raj Prasad Verma; Dr.B.K.Singh
    The study was conducted on Black Bengal goats, Black Bengal and Jamnapari bucks were used for mating. Development of udder, relaxation and loosening of sacro-sciatic ligaments, swelling and widening of vulva, vaginal mucous discharge and restlessness were observed to be the symptoms of approaching parturition. Variations in body temperature during per parturient period were not significant. The symptoms during different stages of parturition were closely observed. The duration of first, second and third stages of parturition was recorded to be 72.57 2.124, 16.81 0.754 and 113.10 5.536 minutes respectively. The influence of litter size on the duration of different stages of parturition was also studied. It was observed that 67.21% parturitions occurred in sitting position and 32.79% in standing position. The frequency of abdominal contraction was observed. 86.67% parturitions occurred during the day and 13.33% during the night hours. The overall mean gestation length was 144.125 0.420. days. The effect of sex of foetus, litter size, parity of dam and breed of sire on gestation length was also observed. The overall mean birth weight of kid was found to be 1.47 0.55 kg. Different factors affecting birth weight of kids were also studied.

    Superovulation, Embryo Collection And Cytomorphology of Genital Organs In Prepubertal And Adult Goats
    (Birsa Agricultural University, Ranchi, 1990) Singh Balraj; B.K. Singh
    1.The experiment was conducted on a total of 48 healthy goats comprising of 16 prepubertal and 32 adult parous goats. 2. Prepubertal goats were divided into four groups comprising of four goats in each group. Pregnant sare serum gonadotrophin and human chorionic gonadotrophin either alone or in combination were used to induce superovulation in different groups. 3.Adult goats were divided into six groups comprising of five goats in each group. Two goats were kept as control. Two injections of prostaglandin 72 alpha vere administered intramuscularly in first three groupe and intra vulvo-submucosally in another three groups at 11 days interval. Pregnant mare serum gonadotrophin was administered in each group forty eight hours before the second injection of PG F2 alpha and forty eight hours after the second injection of PG F2 alpha human chorionic gonadotrophin was administered to each goat. 4. The goats were allowed mating with fertile bucks two times (48 and 72 hours post PG ₂ alpha) during heat. 5. Superovulatory response was judged on the basis of numbers of corpora lutea, corpora haemorrhagica and anovulatory follicles on the day of embryo collection. 6.Embryos were collected surgically on day 3 from the oviduota and between day 6 to 8 from the uterine horas. Cytomorphological and cytochemical studies were conducted. 7. Cytomor phological and cytochemical studies were conducted on the genital organs collected from two of the super ovulated goats. 8. Superovulatory response did not increase by increasing the dose of PMSG from 500 IU to 750 IU in prepubertal goats. 9. Ovarian response was significantly higher in right ovary as compared to the left in prepubertal goats. 10. Average number and percentage of ovulations increased significantly (P/ 0.01) with the incorporation of HOG alongwith PMSG and the best results were obtained with 750 IU PASO and 1000 IU HOG in prepubertal goats. 11. Highly significant effect (PL 0.01) of treatments on the number of anovulatory follicles in prepubertal goats was observed, thus, anovulatory follicles were maximum in the group in which highest dose (750 IU) of PMSG alone was administered. 12. A total of 19 embryos (35.18 percent) were recovered from prepubertal goats. Out of 57.89 percent fertilized embryos recovered, 36.84 percent embryos were normal. 13. Prepubertal goats can be superovulated and may be used as embryo donors.

    Enzyme Immunoassay of Progesterone In Milk of Bovines During Early Pregnancy And In Serum Of Superovulated Cows
    (Birsa Agricultural University, Ranchi, 1988) Gupta, jSharadendu Kumar; A. K. Sinha
    In super ovulated cows, maximum value of serum progesterone was recorded after PMSG injection, or on the day of second injection of PGF₂ alpha. The super ovulatory response was judged on the basis of palpable corpora lutea on the ovaries upon rectal palpation as good ( 12 corpora lutea), moderate (6-12 corpora lutea) and poor (1-5 corpora lutea). The serum progesterone values were observed to fluctuate consider ably. Whereas, the fluctuations were not so marked in one poorly responding cow.
