The bacterial proportion of this consortium has been elucidated regarding its ability to break down and metabolize complex compounds (particularly polysaccharides) which would otherwise be undigestible to the mammalian host. True symbioses such as that found in the rumen between the host animal and the resident ruminal microbial population is rare in nature. The development of Next-Generation DNA Sequencing techniques now allows us to study the microbial composition in greater detail than ever before. The implementation of new technology to characterize the ruminal microbial population, combined with animal performance data, has opened a new field of study for animal scientists and ruminant nutritionists. Ultimately, we must correlate animal feed efficiency and microbial degradative specific activities with the overall ruminal microbial diversity. These correlations will pave a new way for nutritionists to feed cattle more efficiently, precisely selecting in favor of the microbial populations that are most associated with efficient animal performance.","PeriodicalId":314180,"journal":{"name":"Archives of Animal & Poultry Sciences","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115099478","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 drugs used in the treatment of these infections may present toxicity and low bioavailability, delaying the recovery process of these animals. In this context, nanotechnology appears as a new approach for the development of new effective pharmaceutical dosage forms of these drugs, aiming a better biodistribution and decrease of adverse events. Nanocarriers, such as liposomes, have great potential for the delivery of bioactive substances due to their biocompatibility, biodegradability and low toxicity. Liposomes can be used in a variety of fields, including veterinary medicine, and have made great strides in recent decades. Thus, the present study aims to highlight the main and most recent scientific discoveries about the promising potential of liposomes as nanocarriers of drugs in the treatment of parasitic and bacterial infections in domestic animals.","PeriodicalId":314180,"journal":{"name":"Archives of Animal & Poultry Sciences","volume":"101 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131551096","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}

To check this, 66 Ghezel ewes,2-3 years-old and with average weight of 55±2 were chosen and all ewes were allotted randomly into six experimental groups (n=11) as follows: A; Control (only used Basal diet), B; Flushing diet, C; Flushing diet plus vitamin E plus Seleno protein, D; Flushing diet plus vitamin E plus Sodium Selenite, E; Flushing diet plus Monensin sodium, F; Flushing diet plus Saccharomyces cerevisiae yeast. The levels of serum minerals including calcium, magnesium, sodium and potassium concentrations were measured. Results showed that ewes in groups E and F had more serum calcium and magnesium compared with other groups (P<0.01) and the number of female lambs was the highest in these two groups. Ewes in group F had the lowest serum potassium and sodium and ratio of male to female lamb births (0.25) compared to other groups. This study indicated that ewes fed with Monensin and yeast (high Ca & Mg) rich ratios tended to have female progeny, also, the ewes fed with selenoprotein and sodium Selenit (high Na & K) rich ratios tended to have male progeny.","PeriodicalId":314180,"journal":{"name":"Archives of Animal & Poultry Sciences","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115178085","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}

That remarkable quality as a protein source, make them to be also highly attracted by the poultry industry for the same purpose. This raised the issue of investigating other sources of protein for the poultry in other to balance the competitive situation between humans and the chicks. A review of a relatively recent literature reveals that there are several species and varieties of under-utilized legumes with relatively considerable amount of protein as compared to the commonly consumed legumes by humans. However, their experimentation as animal feed suffers a bit in term of documentation. Therefore, it might be wise to intensify research in that line for this is going to be source of cheap input and better economic benefit for the poultry industry.","PeriodicalId":314180,"journal":{"name":"Archives of Animal & Poultry Sciences","volume":"BC-18 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120989668","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}
