People are relying upon oil for primary energy and this will continue for a few more decades. Other conventional sources may be more enduring, but are not without serious disadvantages. The renewable energy resources are particularly suited for the provision of rural power supplies and a major advantage is that equipment such as flat plate solar driers, wind machines, etc., can be constructed using local resources. Without the advantage results from the feasibility of local maintenance and the general encouragement such local manufacture gives to the build up of small-scale rural based industry. This communication comprises a comprehensive review of energy sources, the environment and sustainable development. It includes the renewable energy technologies, energy efficiency systems, energy conservation scenarios, energy savings in greenhouses environment and other mitigation measures necessary to reduce climate change. This study gives some examples of small-scale energy converters, nevertheless it should be noted that small conventional, i.e., engines are currently the major source of power in rural areas and will continue to be so for a long time to come. There is a need for some further development to suit local conditions, to minimise spares holdings, to maximise the interchangeability of the engine parts, and of the engine applications. Emphasis should be placed on full local manufacture. It is concluded that renewable environmentally friendly energy must be encouraged, promoted, implemented and demonstrated by a full-scale plant (device) especially for use in remote rural areas.","PeriodicalId":210831,"journal":{"name":"Scientific Journal of Animal Science","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132760359","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}

Female E. alletteratus reached maturity at 42.54 cm FL. Maturity stage distribution and gonado-somatic index (GSI) revealed that spawning period extended from May to October, with a peak value of GSI attained in August. There is a direct correlation between GSI and hepato-somatic index (HSI), and an inverse correlation of these factors to the somatic condition (K c ). The absolute fecundity has linear relationship with the weights of specimens and weights of ovaries. Yet, curvilinear relationship was found between the absolute fecundity and sizes of females.

Twenty four Red Sokoto goats fed diets containing 0, 10, 20 and 30% baobab pulp and seed meal (BPSM) were used to evaluate the influence of baobab fruit on yield and composition of goat milk. The experimental design adopted was the completely randomized design. Animals were exercised daily inside a fenced paddock where they had access to forage. Dry matter (DM) intake, milk yield, feed conversion ratio (FCR) and milk composition in the goats were measured over a period of 84 days. There were significant (P<0.05) differences in intake, milk yield and FCR of the goats. DM intake increased from 21.5 to 27.5 % of live weight (LW) and milk yield from 333.8 to 441.9 g/day with inclusion of BPSM in the diet. FCR was 1.40, 1.30, 1.28 and 1.29 for 0, 10, 20 and 30% BPSM diets respectively. Milk composition was also significantly (P<0.05) influenced by level of baobab meal in the diet. Total solids in milk increased from 12.23 to 14.10 %; protein from 3.50 to 4.08 %; and fat from 3.38 to 4.45 % with BPSM in the diet.

The PUFA have a high propensity to oxidize, which in turn may affect lipid stability. The malondialdehyde (MDA) showed higher concentrations (31.11vs26.06 nmol.g -1 ) at all times of the oxidation kinetics in meat (A) than (C).

Uterine leiomyomas commonly cause significant symptoms such as anemia resulting from heavy irregular uterine bleeding, Pelvic discomfort, and bowel/bladder dysfunction from pressure. Fibroids have also been associated with infertility and recurrent abortion. Somatic mutations in MED12 exon 2 have recently been reported in uterine leiomyomas. The aim of our study was to see whether MED12 exon 2 mutations occur in uterine leiomyomas of women patients of Tehran Province of Iran. Mutations in exon 2 of the MED12 gene have been reported in 50% to 70% of uterine leiomyomas. To determine the frequency of MED12 mutations in various types of smooth muscle tumors as well as normal uterine myometrium adjacent to a leiomyoma, we selected a total of 23 cases for analysis of MED12 exon 2 mutations by polymerase chain reaction and Sanger sequencing. We found that 65℅ of classical uterine leiomyomas harbored mutations in exon 2 of the MED12 gene. Twelve of these mutations were located in codon 44 (c.130-132). In addition, one fibroids 0/43% displayed a missense mutation in codon 36 (c.107).We also observed two (0/86) exonic deletion type.","PeriodicalId":210831,"journal":{"name":"Scientific Journal of Animal Science","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129328890","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}

Rice straw as a crop residue is widely available in tropical countries and is used in an attempt to meet the energy requirements of growing ruminants. A major limitation to the use of rice straw is their high fiber content, low nitrogen and energy level. Therefore, treatment of rice straw with urea can lead to significant improvement in nutritional quality and greater utilization. The major objectives of the study was to Improve the nutritional value of rice straw using urea, to Evaluate the chemical composition of treated and untreated rice straw using urea. The dry matter, organic matter, crude protein, ether extract, Neutral Detergent Fibre (NDF), Acid Detergent Fibre (ADF), and Ash values are 60.62, 84.01, 12.29,1.07, 62.78, 41.48 and 13.40 for the urea treated rice straw and 75.56, 87.11, 3.22, 0.63, 68.18, 40.70 and 12.34% for the untreated rice straw respectively. The treatment of rice straw with urea has significantly at (P<0.05) reduced its dry matter content by 75.56 to 61.02 % and increased the value of crude protein by 3.22% to 12.29%.It is concluded that urea appears to be as efficient as any other source of ammonia in the treatment of straw. Therefore, the findings of this study will be beneficial to farmers as it will provides improved simple method of formulating local animals’ feeds using simple material like rice straw.","PeriodicalId":210831,"journal":{"name":"Scientific Journal of Animal Science","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115097939","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}
