Livestock plays a vital role in the livelihood of many people in Ethiopia. However, a number of challenges hindered the development of the dairy sector along with its commercialization. Advancing commercialization of the rural generations was a foundation of the advancement and poverty reduction policies of Ethiopia. Cross-sectional data from 385 randomly selected households in Eastern Ethiopia were used in this study to assess the commercialization of cow milk producers. Descriptive statistics and the two limit Tobit econometric models were used to analyze the data. The average commercialization index was 0.434, indicating that each household sold 43.4 percent of the milk produced during the survey period. Ownership of improved breed cow, cooperative participation, access to market information, and quantity of milk produce influenced milk commercialization positively, but household size and distance to the nearest market influenced it negatively. The study suggests strengthening policies to improve rural family planning, strengthening farmer cooperatives to reinforce knowledge sharing among farmers for enhancing farmer resource endowment, and promoting improved breed varieties. The commercialization of milk producers will also expand as a result of policies that try to lower the transaction costs of accessing markets, improve the capacity of rural institutions, and encourage value addition and market links among various market players.

cow milk allergy is a major cause of food hypersensitivity in infants and children.However,to the best of our knowledge,there has been minimal research on the antigenicity of cow milk(CM).As it is currently unknown if enzymatically hydrolyzed cow milk(HM)induces severe immunogenic responses,the potential allergenicity of HM was systematically evaluated in this work.HM effectively attenuated symptoms of weight loss and diarrhea,suppressed levels of mast cell tryptase,and relieved allergic inflammation of the intestine.Moreover,HM reduced the B220+cell count in mouse blood.In addition,in vitro studies demonstrated that gastrointestinal digestion of HM was not resistant to pepsin or trypsin.Thus,HM effectively alleviated allergic reactions and exhibited lower potential allergenicity.These results provide practical information for the future development of hypoallergenic CM products.

The aim of the study was to assess hygienic production practices and to evaluate microbial quality of raw cows’ milk in Cheha district of Gurage Zone, Southern Ethiopia. The study was conducted by interviewing 180 smallholder milk producers from two agro-ecologies (highland and midland) and by collecting 40 milk samples from milk producers, small shops, cafes and consumers for microbial quality analysis. The result indicated that majority of the respondents (96.7%) did not have cow barn and milking area, 57.3% of them clean their barn once and more than once a week. Moreover, milking without hand washing, absence of udder washing, failure to use towel to clean the udder, and use of plastic pail as milking equipment were practiced by 33.9%, 52.2%, 74.4% and 95.6% of the respondents, respectively. Furthermore, higher number of respondents (69.4%) used river water without proper treatment as a major source of water for cleaning purpose and majority of them fail to regularly clean utensils with detergents. Concerning microbial quality, overall mean total bacterial counts (TBC), Coliform counts (CC) and pH values of milk from current finding were 5.675 ± 0.016, 4.414 ± 0.017 log10 cfu/ml, and 5.963 ± 0.081, respectively. In general, overall quality of milk produced as well as marketed in the study area was poor. These were justified from poor hygienic practices and high values of TBC and CC that were significantly higher than the acceptable limits set by Ethiopian Standards for unpasteurized milk. Therefore, adequate sanitary and control measures should be taken at all stages from production to consumer level to produce and supply wholesome milk.

Feedstuff intake plays key role in impacting the yield and quality of milk. In this study, we discussed the contents of trace metal elements in cow milk impacted by different feedstuffs. We detected the contents of Pb, Cd, As, Cu, Mg, Ca, Fe and Zn in different feedstuffs and milk by atomic absorption spectrophotometry. The determinations of Pb, Cd and As contents were by graphite furnace A_AS and Cu, Mg, Ca, Fe and Zn was by flame atomic absorption spectrometry. The results showed that Pb, Cd, As and Cu presented in feedstuffs, but Pb, Cd and As were lowly detected in milk samples, and Cu was not detected in milk samples. The content of Mg in concentrates was lower than that in forages. However, the content of Mg in milk from concentrate feed was higher than that in forage feed. This suggested that the utilization of Mg in concentrate feed was higher than that in forage feed. The contents of Ca and Zn were opposite to Mg, and the utilization of Ca and Zn in forage feed was higher than that in concentrate feed. There was no obviously change law of Fe in different feedstuffs and milk samples. The relationship between the contents of trace metal elements in milk to feedstuffs would provide a theoretical basis for dairy farming. It would be useful for improving the milk yield and milk quality of dairy production.

The aim of the research was to examine ewe and goat cheese labelling on the market of the Republic of Croatia. During the four years (2012-2016) of the research, 133 cheeses from retail supermarket chains were selected by the random-choice method by the responsible inspection of the Republic of Croatia and analysed at the Reference Laboratory for milk and Dairy Products of the Department of Dairy Science at the Faculty of Agriculture University of Zagreb. To check the correct labelling of cheeses, the chemical composition of cheese was examined: the fat content, the dry matter content, the fat in dry matter content, and the water content in the fat-free cheese compound were calculated according to the Ordinance on Cheeses and Cheese Products, which refers to cheeses manufactured in the Republic of Croatia, and Regulation EU (2011) of the European Parliament and the Council on providing information to consumers about food products, which covers foreign cheeses. The presence of cow milk in cheeses labelled as products manufactured exclusively from ewe or goat milk was tested by the reference method using iso-electric focusing to determine any adulteration according to Commission Regulation (2008). The results of analysis in this research show the condition of the quality and correct labelling of ewe and goat cheeses on the market of the Republic of Croatia. Of the 133 cheeses analysed, 67 cheeses (50%) did not correspond to the values stated on the declaration or to legal regulations, while the presence of cow milk was found in 30% of the cheeses analysed. The research results indicate the need to carry out continuous systematic control in the interest of protecting consumers and those manufacturers who are following good manufacturing practices.
