Semi-structured questionnaires and field observations were used to collect the required information from 136 from pastoral and 56 from agro-pastoral. Sheep and goats were kept for a variety of reasons including income generation, insurance (sale for cash to meet unexpected expenditures) and economic security (sale for cash to support foreseeable expenses), social/religious functions and prestige in ownership. In both production systems, next to camels, goats and sheep were ranked as the second and third most important livestock species in accordance to their relative importance. In the current study, there was a significance differences (P<0.05) in the reproductive performance of both sheep and goats between pastoral and agro-pastoral areas. Goats in agro-pastoral areas had noticeably higher average age at first kidding (12.33 ± 0.76 months), and kidding interval (8.76 ± 2.04 months) whereas they had lower age at first mating both for Doe and bucks (9.28 ± 1.85 and 7.98 ± 2.08 months, respectively). Similarly, sheep in the agro-pastoral areas had higher age at first lambing (12.30 ± 1.18 months) and lambing interval (9.16 ± 2.66 months) than sheep found in the pastoral areas. In both production systems twinning ability (0.46), fast growth (0.41) and trekking long distances were the main preferred sheep traits, whereas fast growth, milk yield and twining ability were the main goat preferred traits with an overall index value of 0.37, 0.32, and 0.32, respectively. Genetic improvement programs targeting pastoral and agro-pastoral production system need to be incorporated the traits of preference, multipurpose roles and the existing traditional herding and breeding practices.","PeriodicalId":147546,"journal":{"name":"Journal of Animal Science and Research","volume":"18 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":"122649123","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}

Outbreaks of FMD can have a devastating impact on livestock production and trade, resulting in significant economic losses in the agricultural sector. As a result, vaccination and containment programs have been implemented internationally to minimize the spread of FMDV. The national vaccination program has been implemented in Georgia since 2012, vaccinating Large Ruminants (LR) and Small Ruminants (SR) with trivalent (A, O, Asia1) vaccine twice annually. However, active seromonitoring surveillance still shows a high seroprevalence of the disease, indicating virus circulation. In this study we attempted to estimate the prevalence of different FMDV serotypes in various risk zones within Georgia. A total of 4991 small and large ruminants were tested for the presence of FMDV nonstructural proteins (NSP) in the blood, and the exact serotypes of positive animals were further investigated through structural protein (SP) based assays. The results show that significant percentages (6.6%) of vaccinated animals were affected by FMD, and those positive animals are usually affected by more than one FMDV serotype. As such, our data call upon a stricter vaccination and monitoring program for FMDV in Georgia, especially considering that due to the geographic location of Georgia, the presence of FMD can have significant impact on transit and can be a threat for other countries as well.","PeriodicalId":147546,"journal":{"name":"Journal of Animal Science and Research","volume":"31 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":"116942907","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}

A farm-scale study showed that CNSL feeding to broiler chickens from 0 to 42 days of age improved body weight gain and lowered mortality. Cecal levels of short chain fatty acids increased with CNSL feeding, while ammonia and indole levels decreased. Feeding CNSL decreased the relative abundance of cecal bacteria belonging to some clostridial groups and Ruminococcaceae. In particular, Clostridium perfringens was undetectable following CNSL feeding. A pure culture study showed that CNSL (≥ 6.25 μg/ml) inhibited C. perfringens growth, accompanied by cell surface disruption based on electron microscopic observation. Fermentation profiles of slurry cultures prepared from feces of chickens were altered by CNSL supplementation toward less ammonia production. The lowered ammonia was correlated positively with the abundance of unclassified Lachnospiraceae and unclassified Ruminococcaceae, and negatively with unclassified Enterobacteriaceae and Sutterella. These results suggest that CNSL could exert its beneficial influence on the hindgut health of chickens through impacting the microbiota.","PeriodicalId":147546,"journal":{"name":"Journal of Animal Science and Research","volume":"52 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":"130140842","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}
