The results were based on surveying of 100 households and the markets monitoring in the District. Then, the average goat holding in the woreda was 14.43 heads. Of these, female goats account a higher proportion (48.43%) which is due to the fact that pastoralists kept their female goats longer than the male. Goats in Yabello woreda were solely kept for the purposes of generating cashes used for purchasing grains for family consumption. Considerable, proportions also used for meat and milk consumptions at home. In Study area various routine activities of goat production were shared among different family members. The activities like purchasing, selling and breeding of goats were performed exclusively by the husband. While, the husbandry roles like care of sick animal, milking, and cleaning barn, was left for women. Prom...

The diversified genetic resources is vital for the present and future livelihoods of the large rural farmers in the country. In Ethiopia, there was about 22.6 million heads of goats that were distributed across different agro-ecological zones of the country (CSA 2012). These resources provide a vast range of products and various services such as immediate cash income, meat, milk, skin, manure, risk management and social functions to many smallholder farmers in the country (Adane and Girma 2008). They also serve as sources of foreign currency through meat and live animal exports (Berhanu et al 2006) and have various social and cultural values; nevertheless the wider variations exist among different cultures, socio-economies and agro-ecologies of the country. Ethiopia has large goat resources than most of African countries. The relative importance of these resources and their products varied from region to region and are largely determined by ecological and economic factors. Traditionally, keeping large number of goats was considered as an expression of wealth and/or social status in the rural community. However, with ever increasing human population and drastically shrinking of farming land, goat production is becoming a predominant farming practice, particularly for the landless youth and poor families in the rural areas, while their counterparts, the large ruminants, are facing difficulty during critical seasons of feed shortage (Legesse et al 2008). On other hands, efficient livestock marketing system plays an essential role in assuring better income and benefit for producers. Production without access to market is also a problem for many livestock owners in tropical countries (Lightfoot et al 2005). In Ethiopia, small ruminant production lacks reliable marketing outlets that would benefit small scale small ruminant producers; the pastoralists and consumers (AIS 2003). In many parts of the world, rural people often claim the only reason why they cannot improve their living standards is the difficulties in accessing markets (IFAD 2003). Also with limited opportunities for access to markets goats are often kept beyond their optimum productive levels. This study was therefore, carried out in Yabello woreda of Borana zone. The Borana rangeland was highly endowed with various species of vegetations dominated by mixtures of perennial and woody plants, trees and shrubs with varying composition in response to intensity of grazing and browsing (Coppock 1994). The Long-eared Somali goats have been so far characterized as a dominant goats

Dietary imbalances in dairy cows can be one of fundamental cause of numerous and complicated types of health problems that are usually categorized as metabolic disorders. High producing dairy cows are among highly susceptible animal to such metabolic disorders during their transitional periods; three weeks before and after calving. In these periods, the animal struggles to maintain their calcium homeostasis; which is the most common metabolic disorder of high yielding dairy cows, due to their underlying physiological and pathological factors. Thus, those factors predisposing dairy cows to milk fever are age, stage of lactation and parity, body condition and diet. Usually, the basic principle of controlling milk fever is feeding the cows from diet constituting lower calcium and potassium contents in dry period. So that calcium mobilization from bone would be promoted, which ensures the increased metabolic processes of calcium mobilization during the transition period? Furthermore, supplementations of various anionic salts which includes magnesium sulfate, calcium sulfate, ammonium sulfate, calcium chloride, ammonium chloride and magnesium chloride are commonly used to raise blood calcium level, thus, minimizes risks of milk fever. Also, body condition management of cows during dry period is used to prevent milk fever. Finally, a recent research indicates that serotonin intravenous injections have significantly reduced the incidence of hypocalcemia in high yielding dairy cows.

Traded across different corridors of borderland, Ethiopia's CBLT were traditionally, destined to middle east countries, were the Eastern trade corridor with Somalia involves massive border crossing livestock trade and stand first in terms of traded volume and values. Nonetheless, a significant proportion of CBLT along Sudan, Kenya and Djibouti corridors were also carried out across northwestern, southern and northeastern parts of the country respectively. Livestock sector in Ethiopia, supporting more than 65% of the population and contributes more than 12-15% of total export earnings of the country. However, in recent year, the evidences show that, the trends of official livestock export were declining while, informal export is exponentially increasing. The role of CBLT, on the livelihoods of herders and economy of the country were loomed in the forms of its short-or long-term impacts. In short term, it improves the livelihoods of herders and/or traders through; assisting food security in supplying foods item to the food deficit areas, raising incomes to herders/traders through selling their animals at border crossing/international markets and creates employment opportunity for traders, trekkers or brokers. Whereas, in long term impacts, CBLT have significantly, damaged the economy of our country in several ways. Consequently, Ethiopia have been losing its multi-millions (ETB) of taxes revenue from trade and the devised irrelevant policies and strategies due to the missed livestock trade data (informal) from national statistics led to undermining of sector's economic contributions. In conclusion, any intervention(s) to the CBLT in Ethiopia virtually, requires valuation of its long-and short-term implications to the livelihoods of herders and economies of the country.

Consequently, direct-feds microbials (DFM), is an area of interest of several authors, since last few decades. The probiotics usually, used as DFM for animals are lactic acid bacteria; lactobacillus, streptococci, bifidobacterial, enterococcus and anaerobic fungi species; saccharomyces and aspergillus. Normally, the mechanisms of action of DFM, are modulation of microflora balance in gastrointestinal tract and improvements in digestion and nutrients absorption, sustaining the health of the animals (i.e., through competitive exclusion, secretion of the substances that inhibit the growth or kill and altering gene expression of pathogenic agents) and stimulates the immunity of the animals. Generally, though the effects of host species, types of diet, animal physiological conditions, dosage of probiotics or strain, time of probiotic supplementation and variant strains used, are amongst important factors to be considered, DFM often plays an important role in improvements of milk yield and composition of lactating dairy cows. The DFM of Propionibacterium, Saccharomyces cerevisiae, Lactocbacillus acidophilis, the mixture of yeast products and Enterococcus and combination of L. ecidophilus, L. casei and Enterococcus faecium to dairy cows, significantly improves milk yield and well as the composition. Therefore, DFM, is one of the promising areas of ruminant's nutrition in general or dairy cows in specific, not only because of its nutritional and health benefits to animals, but also due to its negligible residual effects to the animal and animal products.
