Effects of choice feeding a completed feed and corn on the performance of broilers

Poultry feeding systems are likely to change for increased efficiency of production. An experiment was conducted to compare the response of broilers to choice feeding of corn with a standard broiler ration. The treatments consisted of providing broiler feed as the only feed (SINGLE FEED) and access to corn as a choice to a complete broiler feed (CHOICE FEEDING). Weights and feed consumption were obtained at weekly intervals. Samples at the conclusion of the experiment were taken to determine the weight of abdominal fat. Results showed that there was no significant difference in term of liveweight between the two feeding regimes. However, birds given a choice of the broiler feed and corn had better feed efficiency which is reflected by the lower total feed intake. Corn intake was 23.1% of total feed intake in the choice fed birds. In term of carcass colour, birds fed corn as a choice was observed to have a deeper yellow skin colour than the birds fed with broiler feed only

Effect of Increasing Stocking Density on Performance and Heterophil/Lymphocyte Ratios in Broilers

An experiment on space allowance of 0.095, 0.071, 0.057 and 0.048 m2/bird on wire mesh cages was conducted to study their effects on live-weight, feed intake and feed conversion of Orgal broilers from the age of 4 to 10 weeks. Heterophil/lymphocyte (H/L) ratio,an indicator of stress was also studied to determine whether over-crowding would effect this ratio. During the first 2 weeks of the experiment increasing stocking is reduced feed intake and improve feed conversion without significantly affecting growth rate. Overall, birds on the most liberal floor space allowance (0.095 m2/bird) had the best growth rate (39.2 glda») but this was achieved at a significantly higher feed intake (127.9 g/day) and poorer feed conversion (3.3).Conversely, birds on the highest stocking density (0.048 ,rz2lbiTd) had the poorest performance in terms of growlh rate (32.2 g/day) and feed intake(90.6 g/day). Birds on the two higher stocking density were constantly under stress as indicated by their relatively high H/L. ratios from the fourth week, of the study onwards, these two treatments also had higher mortalities. The results of the present study showed that stress associated with overcrowding reduced performance in broilers. A space allowance of 0.071 m2/bird is sufficient under om- local conditions for broiled reared in raised floor cages

Effects of early feed restriction on the performance of broilers

An experiment was conducted to compare the effects of early feed restriction on the performace and abdominal fat deposition in broilers. The treatments consisted of providing feed ad libitum (Full-fed) and three feed restriction treatments of restricting feeding between 8-21 days of age (DOA) either for a duration of 7 days or 14 days. The three feed restriction treatments were Restrict 8-14 DOA, Restrict 8-21 DOA and Restrict 15-21 DOA. Liveweights and feed consumption were obtained at weekly intervals. Samples of both male and female broilers broilers were taken at 43 DOA to determine the weight of abdominal fat, liver and gizzards. Feed efficiency was generally improved by feed restriction, but a compensatory gain was not observed in the restricted groups. Broilers on restricted feeding also had lower mortality as compared to the full-fed broilers. There is no effect of early feed restriction on the weight of the abdominal fat and the dressing percentages but the weights of the liver and gizzard were affected by restriction. Also there was an effect of sex on the weights of the abdominal fat, the liver and gizzard of the males and females

This study aims to determine the potential for developing small-scale fisheries and to analyze the efficiency level of types of fishing gear. The research location is in Kolaka Regency, Southeast Sulawesi Province, the data used is primary data based on the results of direct interviews in the field and secondary data collected from relevant government agencies. Small-scale capture fishery business activities, especially in line fishing gear and basic longlines, have low-efficiency values seen from their profitability values, namely 20%, and 30% compared to fishing gear, Jalah Jatu, and boats, with profitability values of 40% and 50%, respectively. In general, small-scale fisheries in Kolaka are still very dependent on business capital owners to carry out fishing activities. The development of fisheries business, especially in fishing gear that has a low-efficiency value, requires large capital assistance to increase the value of its income. Small-scale fisheries policies in Kolaka Regency are managed by the Capture Fisheries Technical Implementation Unit, especially in the field of empowering small-scale fishermen

Physical, Chemical Parameters and Saphrobic Coefficients (X) as Determinants of Water Quality in the Senapelan River, Pekanbaru

Senapelan River is one of the polluted river in Pekanbaru. The pollutants in this river are originated from domestic activities, tofu industries and palm oil plantation.
