  This study intended to investigate the present management condition and to identify the problems related to Milk Production of Private Dairy Farms of the Rangpur Sadar Thana. About 4 month, door-to-door survey was conducted where 100 farm owners were interviewed. From the survey it was reported that 51% farms belongs to business man, 24% to service personnel, 21% related with agriculture and 4% others. The average number of cows per farm was 15.19. Almost all cows in this farm were crossbred. Most of the cowshed was constructed by straw (48%), tin shed house (26%), half building (22%) and only 4% building. Sixty three, 34 and 3% farm had closed, semi-closed and open house, respectively for their animals with 73% proper ventilation and 33% proper drainage system. Ninety-five percent farm was used as untreated straw and the rest treated straw. Fifty one percent of farmers do not opined to grow fodder crops due to lack of land and the rest lack of seed, lacking of knowledge, lack of awareness and others. The most important constraint of dairy farming was scarcity of feeds and fodder, milk marketing facilities and capital. It is expected that if all these facilities are available dairy farming in Rangpur Sadar Thana will be improved.

  The study was conducted to investigate milk production performance of Black Bengal goat in different parity reared in semi-intensive system. Twenty five pre-pubertal (6-7 months) female Black Bengal goats were selected on the basis of their phenotypic characteristics and their ancestral history from Goat Development farm, Savar, Dhaka. Milk production records of the Black Bengal goat were recorded from January 2000 to December 2002. During the trial they are allowed to graze and concentrate supplement at the rate of 300, 200 and 100 g d-1 to does bucks and kids respectively. Average litter size in the 1st, 2nd and 3rd parity was 1.08, 1.76 and 1.96, respectively. Total milk yield d-1 in the 1st, 2nd and 3rd parity was 275, 312 and 332 g d-1, respectively. Lactation length and milk yield kg-1 live weight lactation-1 in the 1st, 2nd and 3rd parity were 61.56, 66.4 and 67 days and 1.02, 1.2 and 1.2 kg, respectively. Milk yield lactation-1 was 16.37, 20.86 and 21.8 kg, respectively. Milk production performance of Black Bengal goat was better in 3rd parity than that of the 2nd and 1st parity.

  The study was conducted to investigate the reproductive and productive performance of Black Bengal goat in different parity reared in semi-intensive system. Twenty-five pre-puberal (6-7 months) female Black Bengal goats were selected on the basis of their phenotypic characteristics and their ancestral history from goat Development farm, Savar, Dhaka. The animals were vaccinated against peste Des petits Ruminants dewormed and deeped in 0.5% malathion solution. They are allowed to graze once concentrate supplement was fed at the rate of 300, 200 and 100 g/d to does buck and kid, respectively. Different reproductive and productive characteristics of the Black Bengal goat were recorded during 2 years. Young female attained puberty at an average age and weight of 209 ± 32.25 days and 8.08 ± 1.28 kg, respectively. Mean age and weight at 1st kidding were 401.5 ± 32.08 days and 15.41 ± 1.35 kg, respectively. Growth rate at 1st gestation period was 49.56 ± 9.15 g/d. Sex ratio of male: female kids born was found to be 56:44, 48:52 and 51:49 in the 1st, 2nd and 3rd parity, respectively. It required 1.2-1.4 services per conception with average gestation length of 148 days. Average litter size in the 1st, 2nd and 3rd parity was 1.08, 1.76 and 1.96, respectively. Post partum heat period was 48, 43 and 38 days for 1st, 2nd and 3rd parity, respectively. Kidding interval also reduced significantly (p<0.05) from 199 days in 2nd parity to 187 in 3rd parity. Average birth weight of male was higher (1.14 kg) then female (1.06 kg). Total litter size production in the 1st, 2nd and 3rd parity was 1.22, 1.79 and 2.03, respectively. Live weight at kidding in 1st, 2nd and 3rd parity was 15.41, 18.43 and 19.99 kg, respectively. Kid mortality was reduced from 22.2 to 8.16% with the parity. Reproductive and productive performances of Black Bengal goat were better in 3rd parity than that of the 1st and 2nd parity.

  The study has been conducted to compare the productive and reproductive performances of indigenous and crossbred cows. Fifty small diary farms were taken covering 8 Thanas of Jessore and a random sample of 75 cows. Statistical analysis showed significant differences (P<0.01) within the age at puberty, service per conception, calving interval, milk yield and lactation length of different types of dairy cows. In case of gestation length, there were no significant (P>0.05) differences. Shortest age of puberty (6.42 days) and highest service per conception (2.43) were found for Friesian cross. There was no difference in the gestation length (278 days) of the four crosses. The highest value (278 days) was observed in indigenous cow. Friesian cross were observed to have the lowest calving interval (414 days). The highest daily milk yield (7.2 liter) were observed in Friesian cross. Considering above parameters except service per conception, Friesian cross cows were more profitable, acceptable and highest producers than others.

  The effect of ammonia treatment of straw and of barley and lucern-unmolassed sugar beet pulp supplementation on intake, digestibility, nitrogen retention and metabolizable energy of barley straw was studied in sheep. A conventional balance trial was conducted in two periods with 12 sheep, six sheep receiving the same straw in each period, with two sheep on each diet. Chemical analysis of the straw showed a remarkable increase in crude protein content (2.90-8.75% DM) intake (744-939 g/day), dry matter digestibility (56.9-65.3%) nitrogen retention (-10.2-1.4 g/100g N intake) and ME (6.60-8.01 MJ/kgDM) after treatment with ammonia. Supplementation with barley and to lesser extent with lucern-sugar beet pulp, suppressed straw intake but increased total intake up to 600 g dry matter per day.

  The treatments comprised of four sizes of seedling tubers viz. 5.0, 7.5, 12.5 and 17.5 g derived from the TPS progeny HPS II/67 and four depths of planting viz. surface level, 2.5, 5.0 and 7.5 cm with their all possible combinations. Seedling tuber size significantly influenced the growth and yield of potato. Yield was found to increase with the increase in seedling tuber size and the maximum yield (39.34 t/ha) was obtained from the large seeds (17.5g). Depth of planting had no significant effect on the growth and yield of potato. The combined effect of seedling tuber size and planting depth revealed that the maximum yield per hectare (39.42 t/ha) was obtained from the large seedling tuber (17.5 g) with the planting depth of 5.0 cm. Economic analysis indicated that the best economic return was obtained from 17.5 g seedling tubers planted at a depth of 7.5 cm.

  Twenty-four New Zealand white crossbred growing rabbits (Aged 120 days) were used to study the effect of different protein sources on growth and reproductive performances of rabbit does. The animals were fed three diets containing til oil cake (A), soybean meal (B) and gram (C) along with ad-labium green grasses. However daily live weight gain was higher in gram containing diet but not significant (P>0.05) than those received til oil cake or soybean meal. Daily live weight gain of rabbits was 2.34, 2.33 and 3.14 g/day for til oil cake (A) Soybean meal (B) and gram (C) respectively. Feed conversion ratios were differed significantly (P<0.05) among the three treatment groups. Age at first breeding, age at first kidling gestation period, liter size, number of litter alive, number of litter dead and percentage alive were not differed significantly (P>0.05) among the treatment groups. Only kit mortality up to 7 days were differed significantly (P<0.05). Lower kit mortality (12.51) in gram containing feed (C) and increased in group B (36.37) and group A diet (36.37) respectively. Based on the present research findings gram diet may be used as a protein supplement for raising rabbits in Bangladesh. But further research is needed using large number of rabbits in this aspect before final recommendation.
