  Supplemental effect of concentrate was studied on growth and reproductive performance in female goats and sheep under grazing condition. Six females each of goats and sheep aged about ten months and weighing on average, 12.6 and 11.7 kg respectively was used. The supplied concentrate supplement contained wheat bran, rice polish and soybean meal (50:40:10, 350 g/d). Animals of each species were blocked according to live weight and the blocked groups were assigned at random to two feeding regimes (with or without concentrate supplementation) in a 2×2 factorial experiment. Significantly higher (P<0.01) dry matter intake was observed in supplemented group than those of control group (grazing without concentrate) irrespective of animal species. Between sheep and goats significant (P<0.05 to P<0.01) difference was observed in DM intake and live weight gain. Kids birth weight was higher (0.71 vs. 0.55 kg) and gestation length was lower (142 vs. 145 d) in goats given the concentrate supplement than those of control goats. These results suggested that the effect of supplementing concentrate diet be benefited for the growth and reproductive performance of goats and sheep under grazing condition.

  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 effect of protein supplementation was studied on growth and reproductive performance in female goats and sheep under grazing condition. Ten does and six ewes aged about 15 months and weighing on average 13.9 and 14.4 kg respectively were studied for 112 days. Animals were allocated to two feeding regimes [low protein (LP), 168g and high protein (HP), 208g per kg DM] according to live weight. Supplemental feed contained wheat bran, rice polish and soybean meal (LP-43: 43:14 & HP-35: 35:30, 300 g/d). HP diet non significantly (P>0.05) decreased the DM intake in goats. Moreover, significantly (P<0.05) increased live weight gain was observed in goats receiving HP diet. In contrast, sheep receiving the HP diet significantly (P<0.05 to P<0.01) improved DM intake and live weight gain compared with those given LP diet. Average birth weight of kids (0.85 vs. 0.75 kg) and lambs (1.10 vs. 0.83 kg) were higher in both species that received the HP diet than those given the LP diet. Subsequently daily average live weight gain in kids received the HP diet was higher (62.4 vs. 45.4 g/d) than those fed the LP diet up to weaning. These results showed that the effect of supplementing high protein to grazing improved the growth and reproductive performance of goats and sheep.

  The mean yield of rice, rice straw, rice bran, till oil seed, mango tree and jack fruit tree number and other feeds decreased significantly (p<0.01) after shrimp culture compared with before shrimp culture. The salinity and pH of water under shrimp culture area (saline area) are significantly (p<0.01) higher than that of non-shrimp culture area (non-saline area). In case of soil, the average EC value and pH under shrimp culture area are significantly (p<0.01) higher compared with non-shrimp culture area. The chemical composition of green grass, rice straw and rice bran is similar for both of shrimp culture and non-shrimp culture areas. So the production of livestock feeds have been affected following the shrimp farming practices but it do not affect the feed quality.
