A total of 900 hatching eggs (HE) from 40 weeks old parent stock were sorted, graded and purposively grouped on weight basis into small (<50g), medium (50-65g) and large (>65g) sizes (3 groups). Each group was allotted 300 eggs and replicated thrice, with each replicate having 100 eggs in a complete randomised design before incubation for 21 days. Candling of incubated eggs was done on day 18 on group basis and numbers of fertile eggs noted. The chicks were individually weighed and counted to determine hatchability, hatchling weight and cost of production. Thereafter, hatched chicks were allotted into the respective groups and replicated to determine the post-hatch performance. Each replicate has 45 chicks, intensively raised and were fed ad libitum with broiler starter mash for the first 4 weeks of life and broiler finisher mash from 4-8 weeks. Data generated include feed intake, final weight, mortality; weight gain, feed conversion ratio and unit cost of production of chicken were calculated. The data were analyzed by GLM of SAS and Duncan’s multiple-range test was used to separate significance of differences among treatment means at 5% significance level. The medium HE had the best fertility (93.00%), hatchability (95.67%) and cost of producing a chick (N 90.07) when compared with the small and large HEs. The large HE has the best results in terms of, final weight and weight gain, while medium HE has the best FCR, lowest mortality and least cost of production, which are significant at p< 0.05. It is therefore recommended poultry breeders and hatchery operators should consider the use of medium weight (50-65g) HEs in their operations, so as to cut down the production cost. \u0000 \u0000 ","PeriodicalId":347217,"journal":{"name":"Journal of Agricultural Science and Environment","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122101976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study looked at resource use efficiency and profitability of Orange Flesh Sweet Potato (OFSP) in Osun State, Nigeria. Two out of the three zones in Osun State were randomly selected from which six blocks were selected; and thirty cells were randomly selected from the six blocks. Two Hundred and Fifty (250) respondents were randomly selected across the thirty cells for the study. Data were analyzed using linear regression and Pearson Product Moment Correlation (PPMC). Results of the study showed that respondents are agile and active in orange flesh sweet potato production, with mean age of 38.8 years and had wealth of experience (12.6 years). Most (82.4%) of the respondents cultivated orange flesh sweet potato on ridges, 78.8% used hired labour and 92.4% used personal savings for orange flesh sweet potato farming. The average yield of orange flesh sweet potato was 6.20 tonnes/ha, the Total Revenue (TR) was ₦127,999.93/ha while the profit was ₦46,841.93/ha. Major limitations to orange flesh sweet potato production are inadequate finance (83.2%), poor extension service support (80.45), and inadequate market information (74%). Results of linear regression showed that land (t = 3.146, p = 0.001), labour (t = -3.105, p = 0.003), agrochemicals (t = 8.499, p = 0.000), and seeds (t = 3.928, p = 0.004) were determinants of orange flesh sweet potato production (p < 0.05). In addition, correlation revealed negative relationship between constraints faced by the respondents and profit realized from orange flesh sweet potato production (r = -0.72, p = 0.01). The study concluded that orange flesh sweet potato production was profitable. It was recommended that soft credits should be extended to sweet potato farmers by the banks in the study area. \u0000 \u0000 ","PeriodicalId":347217,"journal":{"name":"Journal of Agricultural Science and Environment","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126359355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
