  The study was designed to assess the comparative profitability of selected winter vegetables like potato, cauliflower and tomato. To achieve this objective, total of 75 farmers, 25 producing potato, 25 producing cauliflower and 25 producing tomato were selected. For this purpose, Cobb-douglas production function model was used. Per hectare total cost of production of potato, cauliflower and tomato were 51396.79, 64406.06 and 61663.87 TK., respectively and the corresponding gross incomes were 99401.44, 119165.12 and 93442.24 TK., respectively. The estimated net return of producing potato, cauliflower and tomato were 48004.65, 54759.06 and 31778.37 TK., respectively. For producing the three alternate winter vegetables net return was the highest for cauliflower followed by potato and tomato. It was also found that there was a large variation of yield in producing these winter vegetables among different categories of farms. In the case producing potato and cauliflower, per hectare yield was the highest for small farms followed by medium and large farms. On the other hand in the case of tomato per hectare yield was the highest (48164.50 kg) for large farms followed by medium (47444.10 kg) and small farms (46143.00 kg). It is concluded that production of cauliflower is more profitable than that of others.

  The experiment was conducted at Mirzagonj and Bauphol upazilas of Potuakhali district of Bangladesh to estimate the need for supplementary feeding of rearing ducks. In this experiment, 50 farmers were studied. Sxteen farmers were studied as control group (no supplementation) and other 34 farmers were studied as supplemental group, i.e., 17 farmers for Level-I (50% supplementation) and 17 farmers for Level-II (70% supplementation). The results showed that all the year round scavenging feeds are not available ad-libitum as per requirement for rearing ducks. It was observed that grazing season of ducks may be divided into lean season (summer) that is March to June, abundance season (rainy) that is July to October and moderately abundance season (winter) that is November to February. Rainy season appeared to be the best season for rearing ducks, followed by winter and summer. The results also showed that the crop and gizzard contents contain significantly (p<0.01) higher amount of ME and P in winter and in rainy season than that of summer. It was also observed that the crop and gizzard contents contain significantly (p<0.01) higher percentage of Ca in rainy season than those of winter and summer. The results indicated that the total live weight gain of ducks in supplemented Level-I and Level-II was significantly (p<0.01) higher than that of the total live weight gain of control group. The results also showed that the average daily live weight gain of ducks in supplemented Level-I and Level-II was 8.85 and 9.04 g, which was significantly (p<0.01) higher than that of the average daily live weight gain of control group (7.88 g). It was observed that the total dry matter (DM) intake of ducks in supplemented Level-II was significantly (p<0.01) higher than those of the total dry matter (DM) intake of ducks in supplemented Level-I and control group. It was revealed that the average daily dry matter (DM) intake of ducks in supplemented Level-II was significantly (p<0.01) higher than those of the average daily dry matter (DM) intake of ducks in supplemented Level-I and control group. The results showed that the average time of first lay in control group of ducks was significantly (p<0.01) higher than those of supplemented Level-I and supplemented Level-II. The average duck-day egg production of supplemented Level-I was 43.93% and supplemented Level-II was 45.53%, which was significantly (p<0.01) higher than that of the control group of ducks (23.45%). The observation revealed that the average egg weight of ducks in supplemented Level-I and supplemented Level-II was significantly (p<0.01) higher than that of the control group. The results showed that the average net return of supplemented Level-I was higher than those of the control group and supplemented Level-II group of ducks. It is concluded that only scavenging system of feeding cannot fulfill the nutritional requirements of growing and productive ducks. It may be suggested that minimum level of supplemental feeds should be given to the ducks for getting maximum production under semi scavenging system at farmer`s condition.

  The experiment was conducted to determine the effect of protein supplementation on growth performance in female goats and sheep. Ten does and six ewes aged about 15 months and weighing on average, 13.9 and 14.4 kg respectively were studied in this experiment. Animals were allocated to two feeding regimes [low protein (LP), 168g and high protein (HP), 208g per kg DM] in a randomized block design according to live weight. HP diet did not significantly (p>0.05) increase live weight gain (33.0 vs. 25.2 g/d) in goats. In contrast, sheep received the HP diet significantly (p<0.05, p<0.01) improved DM intake (509.0 vs. 425.9 g/d) and live weight gain (36.6 vs. 10.7 g/d) compared to those given the LP diet. These results indicate that supplementary feeding of high protein diet (208g CP per kg DM) significantly increased growth performance of sheep under grazing condition.
