PREGNANCY DIAGNOSIS IN GOAT BY USING VAGINAL CYTOLOGY AND TRANS-ABDOMINAL ULTRASONOGRAPHY The present study was conducted in a goat farm for pregnancy detection by using vaginal cytology and B-mode real time ultrasound using 5 MHz probe by transabdominal method. Seventeen pregnant does were used for this study. The objective of the study was to determine the earliest days of pregnancy and describe the chronological characteristics of pregnancy from days 22 to days 40 for vaginal cytology and days 25 to days 60 for ultrasonography of gestation. The present study revealed that the pregnancy was detected at 22-25 days after mating by detection of higher average percentages of intermediate cells and few percentage of superficial, keratinized and neutrophil cells. Parabasal cells were absent. The average percentage of intermediate, superficial, keratinized and neutrophil cells during early stage of pregnancy were 81.12%, 9.41%, 7.10% and 2.61% respectively on 22-40th days. In case of real time B-mode ultrasonography, pregnancy was detected at 25 days after mating by detection of gestational sac. The gestational sac was observed only in three does out of seventeen (17.6 %) at 25-30 days whereas the placentomes & heart beat of the foetus were first detected at 31-35 days in six does (35.3%). The foetal leg buds were first visualized at 36-40 days in four does (23.5%) whereas the foetal vertebral column was first observed at 36-40 days of gestation in only three does (17.6%). It could be concluded that vaginal cytology may be used for detection of pregnancy in doe. The real time transabdominal ultrasonography pregnancy can be easily utilized for early pregnancy diagnosis in does at field level. Further work involving large number of animal throughout the pregnant period should be needed. A THESIS BY MD.

SCROTAL CIRCUMFERENCE AND ITS RELATIONSHIP WITH TESTICULAR GROWTH, AGE AND BODY WEIGHT IN INDIGENOUS BULLS ALI, MD. ROMJAN The relationship among the scrotal circumference and testicular parameters with body weight and age were investigated in indigenous bulls. Data from thirty six indigenous bulls were recorded and classified into four age groups namely, Group I (15-18 months, n=7 animals), Group II (19-22 months, n=8 animals), Group III (23-26 months n=12 animals) and Group IV (27 months and above, n=9 animals). Age of the bulls were determined using their dental formula. Live weight body weight of each bull was calculated according to Shaeffer’s formula. Scrotal circumference were measured with a cloth tape and testicular parameters and were measured with a caliper. Body weight, scrotal circumference and testicular parameters were varied in different age groups even in left and right testes of the same animal. The results of different testicular parameters, scrotal circumference, and body weight at different age of Indigenous bulls were significantly (<0.05) different among the age groups. These parameters were increased by the advancement of age. The body weight was lowest in case of age group I (98.14±11.87 kg) and was highest in age group IV (214.22±33.27 kg). The scrotal circumference was lowest in case of age group I (17.14±.63 cm) and was highest in age group IV (24.33±1.31 cm). The average estimated testicular weight was lowest in age group I (86.38±12.18 gm) and was highest in age group IV (214.03±22.93 gm). Various measurements of the testes were highly correlated with each other (< 0.01). Body weight was more highly correlated with the various testicular measurements than age. Moreover age, testis weight, and body weight of Indigenous bulls were highly correlated with scrotal circumference. Scrotal circumference was highly correlated with other testicular measurements as well as testicular volume. Correlation coefficient R2 between scrotal circumference and age in indigenous bulls was 0.599 and between scrotal circumference and body weight was 0.785 which indicates a strong positive relationship among the parameters. Finally from the present study it could be concluded that scrotal circumference is a useful indicator and is an important selection criterion to determine the testicular development and breeding soundness in young bulls.

PREGNANCY DIAGNOSIS OF SHEEP, GOATS AND CATTLE BY BARIUM CHLORIDE AND SEED GERMINATION INHIBITION TEST AT FIELD CONDITION KHATUN, MOST. NASRIN Twenty one days non-returned cows and heifer (n=40), sheep (n=20) and goats (n=20) of pirganj and biral upazillas of Rangpur and Dinajpur Districts, respectively, were used to diagnose pregnancy using seed germination inhibition and barium chloride test. Animals were randomly divided into three groups. No germination with the change of colour having shoots length less than 1 cm were considered Pregnant. Germination 35-60% with moderated shoot length (4 cm), indicated non-pregnant. In controlled petri-dish, 60-80% germination with shoot length of about 6 cm were considered non-pregnant can go to dissimilar. The percentage of pregnant ewes diagnosed by seed germination inhibition test during 21-150 days of pregnancy were ranged from 21-35 days 75% (3/4) and 35-60 days 80% (4/5) of pregnancy results respectively. In goats pregnancy were ranged from 21-35 days 80% (4/5) and 35-60 days 87.5% (7/8) of pregnancy results respectively. The cows at 21-35 days pregnancy showed negative result. It was revealed that percentage of pregnant ewes diagnosed by barium chloride test during 21-150 days of pregnancy ranged from 21-35 days 75% (3/4) and 35-60 days 80% (4/5) of pregnancy results respectively. The goats ranged from 21-35 days 80% (4/5) and 35-60 days 87.5% (7/8) of pregnancy results respectively. The cows of 21-35 days pregnancy showed negative result. Seed germination inhibition test and Barium chloride test from 35 days of pregnancy in cow, the accuracy of pregnancy diagnosis was 90% (9/10). Hundred percent positive results were obtained from day 60-240 of pregnancy in cows. The total accuracy of pregnancy diagnosis was 90-100% from the day 35 to 240 by seed germination inhibition test and barium chloride test in cows A THESIS BY MOST.

EFFECTS OF FOCUS FEEDING WITH VITAMIN AD3E INJECTION ON PERFORMANCES IN JAMUNAPARI GOATS SHARMA, SNIGDHA The present study was conducted in a goat farm to adopt the strategies for focus feeding and observe the effects of focus feeding with Vitamin AD3E injection on reproductive performances and milk yield in Jamunapari goats. For this study, 30 clinically healthy does were used. All experimental goats were assigned into two groups as Group I and Group II. The goats of Group I were maintained on natural grazing with traditional feeding practice. While goats of Group II were supplemented with concentrate feed along with natural grazing and also vitamin AD3E injection. The supplements were given from 45 days before mating time up to 45 days after kidding. Vitamin AD3E was injected at every alternative day from 30 days before kidding up to kidding. There was no significant difference (p>0.05) in duration of estrous in indigenous does between two group. The observed duration of estrous was 46 ± 3.09 and 43 ± 3.82 hours respectively. Highest pregnancy rate (100%) was observed in does of Group II compare with Group I (86.67%). Though there was no significant differences (p>0.5) in gestation length between two groups, Group I goats showed slightly higher (143.3 ± 1.7 days) value than Group II (142.7 ± 2.7 days). Significantly (p<0.05) higher litter size was found in Group II (1.93± 0.7) than Group I (1.27±0.7). Significantly higher (p<0.5) kidding rate was observed in does of Group II (100%) compared with Group I (86.67%). Single kidding rate was higher (46.15 %) in Group I than Group II (26.67%). Twinning kidding rate were higher in Group II than Group I. Triple kidding rate were observed 7.69 % in Group I and 6.67% in Group II. Quadruple kidding was only observed in Group II (6.67%). Average daily weight gain in kids of Group II was significantly (p<0.01) higher than kids of Group I (0.0733±0.0076 Vs 0.0359±0.0205). Infertility rate was higher (13.33 %) in Group I than Group II (0%). Kid survival rate was significantly (p<0.05) higher (100 %) in Group II and 57.14 % in Group 8 I. The post partum onset of estrous was significantly shorter (p<0.01) in goats Group II (46 ± 0.5 days) than controlled group (78.8 ± 9.17 days). Average milk production was higher in Group II (946.12 ± 146.3 ml) than Group I (535.5 ± 138.3 ml). It could be concluded that focus feeding before breeding along with vitamin AD3E injection is effective, safe and practical technique and it may be used for improving reproductive performance of does, preventing mortality and increasing newborn vitality and increasing milk production. Further work involving large number of animal should be needed.
