Therefore, a study was completed comparing yearling goats grazing grass pasture supplemented with SL or non-condensed tannins (CT) commercial pellets (control group), respectively, at 1.5% of body weight for 14 weeks, and then after 14 weeks, they were only fed with non-CT pellets at 2.5% of body weight for additional six weeks. Animal body weight was measured at the start of the trial, the 7th week, 14th week and end of the trial. Fecal samples were taken weekly to determine GIN egg output (fecal egg count; FEC) and coccidial oocyst production (fecal oocyst count; FOC). Blood samples (to determine packed cell volume; PCV) were taken weekly to monitor anemia status of the goats, and on days 0, 98 and 137 to determine aspartate aminotransferase (AST), alanine aminotransferase (ALT) and creatine kinase (CK). The study revealed that supplemental SL leaf meal pellets had no effect on FEC, but reduced FOC (P < 0.05) and improved FAMACHA© scores (P < 0.001) in the goats, and the SL supplemented goats tended to gain more weight (P = 0.07) than control animals during the first 49 d, following initiation of pellet feeding. There were no treatment effects on enzymes related to liver function or muscle turnover (AST, ALT and CK), suggesting that there was no muscle damage due to long-term feeding of SL pellets. In conclusion, feeding supplemental SL pellets at 1.5% of body weight on pasture may be a viable strategy for improving \u0000health and productivity of yearling goats.","PeriodicalId":14977,"journal":{"name":"Journal of agricultural science & technology A","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79073286","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}

There were total 16 late starter local pigs fed with four treatment feeds based on block design with four pigs in each treatment. The four treatment feeds offered consisted of: commercial starter feeds Charoen Pokphand 552 (T0), basal feeds + yeast 2% of daily feeds requirement (T1), basal feeds + yeast 4% of daily feeds requirement (T2) and basal feeds + yeast 6% of daily feeds requirement (T3). Feed intake, daily weight gain, feed conversion efficiency, protein and crude fiber digestibility were evaluated in the study. The findings showed that supplementing S. cerevisiae into low quality local-based diet improved 0.9%-2.7% feeds’ crude protein, 10%-19% feeds intake, 1%-6% daily weight gain, 3%-4% crude protein digestibility and 4%-5% crude fiber digestibility, but reduced feeds conversion efficiency by 0.3-0.4. The conclusion drawn is that supplementing S. cerevisiae (yeast) up to 6% improved performances of starter local pigs fed low quality feeds and performed the similar result with feeding commercial starter feeds Charoen Pokphand 552. Further research by widening the range and increasing the level of yeast supplementation could be done.","PeriodicalId":14977,"journal":{"name":"Journal of agricultural science & technology A","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74028482","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}

Aiming to obtain information about the knowledge of veterinarians on AW during the practice of their professional duties, in September 2016, an on-line questionnaire was sent to the veterinarians who were in the Educación Continua database. The questionnaire had four sections: a general gathering information and three additional sections, one for each veterinarian professional field (large animal’s health and production, small animal’s health and food industry). From 1,804 questionnaires sent, 388 answers were obtained. There were 69% attended at least one AW course, and 89.9% were willing to attend another AW course. And 63.5% considered the information received to be very useful for their daily activities, 95% considered that AW should be included in the veterinary studies curriculum, while 53.3% declared not having knowledge about the regional animal welfare strategy (RAWS). The majority of the veterinarians considered the acquired knowledge very useful and are eager to obtain more information. It is necessary to keep working to include AW in the veterinary studies curriculum as well as continuing with the diffusion of good practices and AW principles, based on the national and international norms.","PeriodicalId":14977,"journal":{"name":"Journal of agricultural science & technology A","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85492825","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 region is of major socioeconomic interest for the country. The climatological study of this region shows the variability of each parameter. The objective of this study was to analyze meteorological parameters trends and to assess the space-time evolution of some agro-climatic risks related to the main trends observed in the meteorological parameters regime of this region. In this study, programming tools were used for processing and analyzing meteorological parameters data, including temperatures, rains, wind, evaporation and storms measured in this observatory from 1931 to 2014. The interannual, annual and daily variations of these parameters were obtained, as well as temperature, precipitation anomalies and agroclimatic indexes trends. The analyzing of these variations explained that September is the rainiest months, and the year 1932, 1957 and 1970 are normal, rainy and dry year, respectively. The evaporation increased since 1971 from January to March and November to December. A positive temperature anomaly was observed since 1973 with the maximum 26-33 °C and the minimum 16-21 °C. A dominant westerly wind with a speed of 2.6 m/s was determined. Agro-climatic parameters in N'zerekore have high variability. From 1931 to 2014, three major periods can be distinguished: a wet period from 1931 to 1977, a dry period from 1978 to 1994 and rainfall variability from 1995 to 2014. The trend of these parameters explains the impact of climate change in this part of the world. This is exacerbated by human activity (deforestation), thus mitigation measures are necessary. It would be useful to extend this study throughout the country.","PeriodicalId":14977,"journal":{"name":"Journal of agricultural science & technology A","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83561024","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}

Embryogenic callus were recorded 100% mortality when cultured on MS medium containing 100 mg/L kanamycin with different cultivars, thus it was chosen for the selection of transformed explants. Embryogenic callus of Medjool and Khalas were incubated with Agrobacterium tumefaciens strain LBA 4404 for 0.5, 1, 2, 4 and 24 h on LB medium. After the incubation periods, embryogenic callus was transferred to MS medium with 0.1 mg/L NAA, 0.05 mg/L BA, 250 mg/L carbenicillin and 100 mg/L kanamycin for detection of transgenic embryogenic callus. Polymerase chain reaction (PCR) was used for the rapid screening of Cry3Aa gene. For screening, total genomic DNA was isolated from transformants. Using primer specific to Cry3Aa gene (forward and reverse), a PCR product with a size of about 2,000 bp was amplified when all nucleic acid from the transformants were utilized as templates. PCR analysis confirmed the appearance of the transgene of 2,000 bp in one individual plantlet. Presence and integration of foreign Cry3Aa gene in regenerated kanamycin resistant embryogenic callus was also confirmed by Southern blot hybridization.
