{"title":"Local sheep and goat reproductive performance managed under farmer condition in Southern Ethiopia","authors":"Hussein Taju","doi":"10.5897/ijlp2018.0509","DOIUrl":"https://doi.org/10.5897/ijlp2018.0509","url":null,"abstract":"Sheep and goats represent an important component of the farming system by providing about 12% of the value of livestock products consumed and 48% of the cash income generated at the farm level. Although diverse sheep and goats resources are found in Ethiopia, their productivity is low; the sector has not received a great deal of attention from scientists, administrators and legislators. Strategic recording and documentation of the performances of the animals in their native environment under farmer’s condition is very essential. Current survey study was conducted in Dwaro zone, Southern Ethiopia to assess productive and reproductive performance of sheep and goat kept under framers management condition. Primary data were collected from 270 household selected randomly, while secondary data from relevant written documents. Survey result showed that ewes and does were weaned on average at age of 126.2±1.44 and 145.5±1.48 and 249.0±3.10 days in order and weaning age was significantly longer in highland and midland as compared to lowland whereas ewes age at puberty does not vary significantly across agro-ecological zone but does age at puberty is significantly shorter in highland. In addition, the finding indicated that age at first lambing and kidding was 408.0±3.32 and 393.5±3.05 days, respectively. Age at first lambing was not significantly (p>0.05) affected by agro-ecological zones while age at first kidding of does was significantly (p<0.05) longer in lowland (408.6±7.75 days) as compared to midland (385.6±4.31 days) and highland (386.2±0.83 days). Furthermore, survey result revealed that mean kidding and lambing interval was 269.9±3.08 and 269.0±2.89 days, respectively and kidding interval was significantly shorter in highland (263.5±6.0 days) and midland (264.0±5.89 days) relative to lowland (281.7±3.70 days), whereas lambing interval was not affected by agro ecological differences. Furthermore, the survey pointed out that household in the study area slaughtered sheep and goat at mean age of 258.1±4.39 and 255.6±2.49 days in sequence. Lowland household were preferred to slaughter sheep and goat at younger age as compared to midland and highland household for both species that preferred slaughtering of sheep and goat at older age. Feed and other related management improvement and implementing strategic breed improvement is the area that need further work in the future. \u0000 \u0000 Key words: Age at first kidding, lambing interval, weaning age, Dawro.","PeriodicalId":14143,"journal":{"name":"International Journal of Livestock Production","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75733438","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}

Chicken production encompasses into traditional scavenging, small and large-scale market orientated systems based on the objective of the producer, the type of inputs used and the number and types of chickens kept. In Ethiopia, indigenous chickens produces 10 to 20 eggs per clutch and 30 to 65 small eggs per hen per year in 3 to 4 clutches. Local chickens reach slaughter/market age at 8 to 12 months with 0.6 to 2.5 kg average weight at farmer management system. Indigenous chickens require long time to reach sexual maturity and takes longest time to recover reproductive cycle by local broody hen. The average mortality rate was highest and which affects both productive and reproductive performance of indigenous chickens by reducing survival rate. There were huge number of indigenous chickens existing in Ethiopia but productivity was disproportional to the number of chickens. The major constraint which affects productive and reproductive performance of indigenous chickens are diseases and predators, feed shortages, lack of training and extension services, and lack of proper marketing systems. Conclusively, lowest productive and reproductive performance was recorded which needs further improvement by adjusting training and extension service for farmers. \u0000 \u0000 Key words: Indigenous chickens, reproductive performance, productive performance, Ethiopia.","PeriodicalId":14143,"journal":{"name":"International Journal of Livestock Production","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81576078","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}

The objective of this study is to evaluate the proximate value, in-vitro digestibility of dried poultry manure (DPM) and its subsequent effect on growth, pH, and volatile fatty acid production of indigenous goats in Zimbabwe. Eighteen goats were randomly allocated to two treatment diets: grazing veld grass plus ad libitum browsing of Luecaena leucocephala (T1) and 25% dry poultry manure plus 75% maize meal (MM) (T2), in a completely randomised design.  Three samples of 2 g each T1 and T2 diets were subjected to standard procedures, for proximate analysis; a two stage Tilley and Terry was used to evaluate dry matter (DM) and organic matter (OM) digestibility of the diets. The results show no significant differences between treatment diets for DM, ether extract (EE) and Ash; however T1 had higher (P 0.05).  Diet and sex of animals significantly influenced (P<0.05) the total VFA production. Male animals in T2 exhibited the highest (P<0.05) total VFAs.  In conclusion, although there were some nutrient inadequacies (ash, ADF) in poultry manure feed, it can support goat production at a marginal scale and positively influence pH and VFA production. \u0000 \u0000 Key words: Goats, digestibility, poultry manure, nutritive value.","PeriodicalId":14143,"journal":{"name":"International Journal of Livestock Production","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84522854","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}
