A simple random sampling technique was employed to select the household’s (HHs) and 96 representative households were selected. Data were collected using group discussions, structured questionnaire, secondary data and personal observations. As it was identified in the study district, natural pasture, crop residues and agro-industrial by-product were major feed resources for the livestock. An average of 129,461.0156 tons of feed dry matter (DM) per year was produced in the district from the major available feed resources, and the demand for maintenance requirement of the livestock population in the district was 190,054.416 (tons DM/year) and this showed that a deficit off 60,593.4004 (31.88%) tons of DM per year in the district. Drought, feed shortage, water scarcity, disease and parasite, market and theft and predator were assessed to be the major livestock production constraints. Generally, the results from this study confirmed that the total dry matter produced from different feed resources in to the study  area was not enough to satisfy the dry matter requirement of livestock to support the livestock production in to the study area, which suggest that the main focus needs to be refining the existing feed resources through restoration of tainted grazing areas, introduction compliant feedstuff production, improving feed utilization practices  and introduce and promote the crop residue feed improvement. \u0000 \u0000 Key words: Feed availability, feed balance, feed requirement, feed resources.","PeriodicalId":14143,"journal":{"name":"International Journal of Livestock Production","volume":"17 1","pages":"43-51"},"PeriodicalIF":0.0,"publicationDate":"2020-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79273788","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}

Questionnaires were administered on three kebeles and 90 respondents’ from scavenging chicken keepers, and 10 intensive farms were interviewed. The respondents’ were stratified into 1st,  2nd and 3rd strata having 1-10, 11-20 or 21-49 chicken, respectively. Chicken houses were constructed with material stone wall and grass roof (40%). From the total respondents, those not cleaning the chicken house were 45.6%. Also, while mother took charge of sharing and offering feed for chicken, selling egg and chicken at 53 68, and 50%, respectively; and father is largely responsible for shelter constriction (17%); both mother and father participated nearly equally (29 and 28%) in purchasing drug for chicken. All respondents provided supplementary feed and water for their chicken with majority (63%) of feed supplemented being maize. Moreover, it was observed that feed supplementation can only improve egg production and growth (26.7%) in summer (July - September) session if supplemented most often (78.9%).

However, Newcastle disease largely compromises the production of this precious bird under backyard production settings. The purpose of the study was to assess antibody responses and growth performance following Newcastle disease vaccination in kuroiler, broiler, and local Tanzanian chickens raised under the same tropical environmental condition. In the experiment, a total of 358 chickens comprised of 127 kuroilers, 121 broilers, and 110 local Tanzanian chickens were raised for seven weeks, and body weights were recorded weekly. Birds were vaccinated at four weeks, and blood samples were collected at days 10, and 21 post-vaccination for antibody titres quantification by ELISA test. Results demonstrated higher (P < 0.05) antibody titres in kuroilers (3.81 ± 0.06) as compared to local chicken (3.73 ± 0.07) and broilers (3.53±0.06) at day 10 post-vaccination.

Four comb types were observed, with strawberry (51%) being most dominant, as was whiteness of ear lobes (57%). Rounded ear lobe shape (92%) and curved beaks (99.6%) were both almost universal. Beak colour varied between green, black, yellow and brown with the latter most prevalent (51%). Evenly distributed feathers were most common (99.8%) whereas naked-neck phenotype was rare (0.2%).
