    Micronutrients Status And Their Supplementation In Relation To Reproductive Performance of Crossbred Cows
    (Birsa Agricultural University, Ranchi, 2001) Asad Hussain; A.K.Sinha
    The present study was carried out at Military Dairy Farm, Namkom. A total of 36 crossbred cows (first to third calvers) were selected and distributed in three groups. 2. Two Nutrisacc boli twice daily orally were fed to each animal in one group (T₁) and 4 gm of Biochrome powder once daily in second group (T₂) from 15 days before the expected date of calving to 15 days after calving. Third group (T3) was kept as control. 3. Four micronutrients viz., iron, copper, manganese and zinc were estimated in sera samples of 18 cows (six from each group) on 15 days before expected date of parturition (D-15), on the day of parturition (D'0') and on day 15 after parturition (D+15) were estimated by Atomic Absorption Spectrophotometry (GBC Model 902). 4. Increasing trends in average values of micronutrients were recorded in both the treated groups (T, and T₂) at D '0' and D +15 with the highest values at D+15. 5. Highly significant effects of treatments on average serum values of micronutrients were observed at D+15. 6.Average serum micronutrient values were higher in both the treatment groups (T, and T₂) as compared to control group (T₂). 7. Average serum micronutrients values were higher in Nutrisacc bolus fed group (T₁) than Biochrome powder fed group (T₂). 8.Average interval from parturition to first estrus was shortest (76.57) 11.09) in Biochrome powder fed group (T₂). 9 Average interval from parturition to fertile estrus was also shortest (129.46± 16.51) in group T₂. 10. Average number of insemination per conception was lowest (2.53 +0.38) in group T₂ 11. Lowest incidence of retention of foetal membranes (6.66 %) was recorded in group T₂ 12. An increasing trend with respect to average birth weight and subsequent body weight of female cows was observed in group T₂ 13. Average milk yield was higher in groups T, and T₂ than in group T₁ recorded at weekly intervals. 14. Better reproductive performance, more body weight gains in female calves and better milk yield were observed in the cows of Biochrome powder fed group (T₂).

    Induction of Farrowing with Xylazine, Prostaglandin and their Combination
    (Birsa Agricultural University, Ranchi, 2001) Brijmohan Mahto; M.P Sinha
    Our study employed prostaglandin in combination with xylazine to induce farrowing. This treatment allowed a more precise control of parturition of sows corresponding to normal working hours. No adverse effects were observed in either the piglets or sows. The combined. prostaglandin-xylazine treatment can therefore be considered an effective measure for inducing farrowing.

    Reproductive Profile of Crossbred Cows For Augmenting Productivity
    (Birsa Agricultural University, Ranchi, 2001) Bijay Kumar Sahu; M.P.Sinha
    The present study was carried out at Military Dairy Farm, Namkom, Ranchi. The available reproductive data of 241 animals and 791 calvings since 1987 to 2000 were scanned and various observations were recorded. The important findings have been summarized as follows: i) The overall conception rates of the herd was found to vary between 45.74 and 51.89 per cent. The overall services required per conception was recorded to be 1.98, the overall mean service period was 97.2 days. 11)Among the infertility problems in the herd, the overall incidence of anestrus was 52.27 per cent, endometritis, 5.01 per cent, cystic ovarian degeneration, 2.27 per cent and repeat breeding, 32.27 per cent. iii) Among the different periparturient disorders, the incidence of retention of fetal membrane, abortion, premature birth, still birth and dystocia was recorded to be 8.03 per cent, 6.06 per cent, 4.09 per cent, 0.9 per cent and 0.35 per cent respectively. The overall periparturient disorder percentage in the herd was 19.24 per cent. iv) The conception rate with 1st AI was 46.66 per cent. v) The average values of age at first heat and age of first fertile oestrus of herd was 696.04 ± 8.56 and 762.83 ± 9.82 days respectively. vi) The overall mean for age at first calving was estimated to be 1013.48 # 9.83 days. vii) The estimate of overall mean for calving interval varied between 411.38 19.52 days to 455.11 18.0 days. viii) The overall gestation length varied between 259.33 +2.33 and 290.00 0.0 days. ix) The average herd service period was recorded to be 185.45 ± 8.10 days. x) The overall lactation length of the herd was 305.69 ± 2,97 days whereas the overall mean for lactation yield was 2973.25 44.25 kg. xi) The overall HCI, PCI and ACI during the present study were recorded to be 434.76 ± 6.38, 455.45 +9.79 and 455 45 days, respectively. xii) The fertility index of the herd was found to vary during different parities and ranged between 41.27 and 52.92. It was highest during 4th parity and minimum during 1st parity. xiv) It was felt during the study that accurate recording of reproductive events. was extremely important in order to come to any conclusion. Moreover, the fertility index calculated with this farm during the present study needs to be compared with come more farms for conclusive reporting.

    Role of Certain Therapeutic Agents for Augmentation of Fertility in Swine
    (Birsa Agricultural University, Ranchi, 2000) Niranjan Kumar Singh; Balraj Singh
    1.The present study was conducted on 73 sows of "T & D" breed distributed in six groups. 2. Different treatments viz., Gestaforte vet bolus, Uterotone liquid, Betadine liquid along with Payapro bolus and Betadine liquid in four different treatment groups were administered within 24 hours of farrowing. Two groups were kept as control. 3. Highly significant effect (P < 0.01) of treatments on weight of piglets at various ages was recorded during pre-weaning periods from birth to 56th day of age. 4. Significant influence of treatments on litter weight was noted at different ages during pre-weaning periods except at birth, 5.Significant effect of Gestaforte vet bolus on average litter weight was noted at 10th, 20th, 30th, 40th, 50th and 56th day of age, except at birth in comparison to the subsequent farrowing in which no treatment was given. 6. Non-significant effect of treatments on litter size was recorded at all the ages during pre-weaning period. 7. Non-significant difference with regard to litter size was found between treated and subsequent farrowing non-treated sows in all the four treatment groups at all ages except at 10th day in group T₂. 8. The shortest interval of fertile estrus (10.58 1.86 days) was also observed in group T However, non-significant effects of various treatments on the interval of fertile estrus was observed. Farrowing interval was lowest (179.581.91 days) in group T, in which Betadine liquid intrauterine was administered. However, non-significant effect of treatments on farrowing interval in sows was observed. 10. Non-significant difference in the average percentage of still born piglets in all the treatment groups was observed. 11. Non-significant effect of treatments on mortality percentage of piglets at different ages was indicated. Non-significant difference in mortality rate in treated and untreated next farrowed piglets in all the treatment groups at all ages was recorded. 12. Post farrowing intrauterine therapy reduced duration of fertile estrus and farrowing interval but higher piglet weight at weaning was recorded with oral therapy groups. 13. The difference in return from the sale of piglets just after weaning was Rs. 394.80 and 283,50 in groups T, and T, respectively. The anticipated net extra return in T, and T, groups were found to be Rs. 3,51,016.00 and Rs. 1,82,644.50 respectively. 14. Oral therapy groups of sows showed higher profitability in comparison to intrauterine therapy groups of sows.

    Management of Bovine Reproduction with Dinoprost in Dairy Farms around Ranchi
    (Birsa Agricultural University, Ranchi, 1998) Vivek kumar Sinha; Balraj singh
    Studies on incidence of infertility and various types of infertility in cattle were conducted in 34 farms, categorised according to the strength of animals. Out of 731 animals, 327 cases (44.73 %) of infertility were recorded. No effect of herd size was observed on the incidence of infertility in heifers and cows. Likewise, incidence of infertility separately in heifers and cows was 51.22 per cent and 43.42 per cent respectively with no significant difference. With respect to types of infertility in cattle, the incidence of true anestrus was the highest (26.41 %) followed by apparent anestrus (24.63 %) but they also did not differ significantly. Similarly, the incidence of true anestrus in heifers was highest (53.97 %) followed by apparent anestrus (25.40%) and they differed significantly. In cows, the incidence of true anestrus (20.83%) and apparent anestrus (21.60 %) was almost equal and the difference was non-significant. Postpartum reproduction management in 20 cows was conducted by ad ministering 25 mg Dinoprost intramuscularly within 6 hours of parturition. Lower incidence of retention of fetal membranes(15.00 %) was noted in 'Dinoprost' treated group, than the control group (50.00%). Both the groups differed significantly ( p<0.05) . No significant effect of 'Dinoprost' was observed with respect to reduction in diameter of cervix and uterine cornua of treated cows. Postpartum estrus interval was significantly shorter(p <0.01) in treated group than that of untreated groups. Similarly, the postpartum fertile estrus inter val was also significantly shorter (P < 0.01) in treated cows than than of untreated cows. The conception rate was significantly higher (p < 0.05) in treated cows (70.00%) as compared to untreated cows (33.33%). Two injections of 'Dinoprost' (25 mg each) at 11 days interval was administered intramuscularly to 50 apparent anestrus cows. Forty six cows (92.00 %) came into heat within 96 hours of treatment which was significantly higher (p <0.01) than that of control group (38.88 %). The overall conception rate in the treated group (80.43%) was significantly higher (p <0.01) than that of control group (42.86%). With the same treatment schedule 73.68 per cent of apparent anestrus buf faloes came into heat as compared to 38.46 per cent of untreated controls and the difference was significant (p < 0.05) The overall conception rate was significantly higher (p < 0.05) in the treated buffaloes (71.43 %) than that of control group (20.00 %). Early detection of non-pregnancy was performed by Prostaglandin Induced Milk Flow Test (PG-IMFT) using 2.5 mg 'Dinoprost' intravenously and let down of milk was observed. The drug was administered on days 20-22, 30 and 40-45 post insemination. Estrus animals were included as control. The pregnancy was confirmed by per rectal palpation 45-50 days post insemi nation. The test was accurate in 88.23, 84.21 and 68.75 per cent on days 40-45, 30 and 20-22 post insemination respectively in positive cases whereas accuracy was 100.00 per cent in negative cases (non-pregnancy). Overall economic gain in postpartum reproduction management in cattle was Rs. 3017.38 per cow. In the management of apparent anestrus, the gain was Rs. 2156.58 per cow and Rs. 2043.02 per buffalo.
