Abstract

Bovine mastitis is an inflammation of the mammary gland with local and or symptoms that occasionally result in a systemic infection. This disease has a profound impact on animal welfare and milk quality, and the most costly disease affecting dairy cows. The bacteria Staphylococcus aureus is one of the most frequently isolated pathogens from both subclinical and clinical infections. This study was conducted to investigate the phenotypic and genotypic characterization of S. aureus involved in dairy cow mastitis in West Algeria. A total of 141 isolates of S. aureus isolated from quarter milk samples were collected from dairy cows. All retained S. aureus species contained gyr gene and were identified by molecular typing. The presence of resistance was evaluated in S. aureus. Staphylococci antimicrobial resistance was performed by detection of mecA gene. Several virulence factors including toxin of the Pantin Valentine leukocidin coding gene (pvl) were also investigated by polymerase chain reaction (PCR). Only one strain of S. aureus was mecA - and pvl+ gene.

Key words: Mastitis, S. aureus, Gyr A, PCR, mecA, pvl.

Abstract

In this study, it was aimed to determine the factors affecting farmers’ decision to benefit from milk incentive premium. The study was carried out in the Northwest region of Turkey, which is considered one of the most productive milk producing region and the Northeast of Turkey, where the number of cattle is the highest. The number of survey conducted in the provinces of these two regions was determined to be 540. Based on the data obtained, the regression analysis was performed using LIMDEP statistic package program with descriptive statistical analysis and univariate (binomial) probit procedure. According to the results of the study, it was determined that the farmers in the Northwest benefited more from the milk incentive premium, produce more milk for market, have higher levels of education than that of those in the Northeast, which was average. It was also observed that they generally have more productive breeds of cattle in their farms. Considering all these results, it could be thought that, it is necessary to perform animal growing more consciously in the Northeast and thus, it is a need in this region to train the animal growers, and the support policies should be restructured by considering regional differences.

Key words: Turkey, milk incentive premium, probit, regional differences.

Key words: Ethiopia, cattle, production, reproduction.

Abstract

Potential of ethanolic extract of Terminalia arjuna Wight & Arn bark to enhanced the shelf life and anti-oxidant ability of clarified butterfat (ghee) was evaluated using accelerated oxidation tests. Seven percent by weight of ethanolic extract of T. arjuna Wight & Arn bark was effective in retarding the auto-oxidation of both cow and buffalo ghee during storage. It had significant (P<0.05) ability to enhance the antioxidant potential of ghee in terms of its radical scavenging activity. It also improved phytosterol, content in ghee. Shelf life of the Arjuna ghee samples was 8 days at 80±1°C as compared 2 days in the control. Findings suggested that ethanolic extract of T. arjuna Wight & Arn could be used as a natural antioxidant and enhancing the phytosterol content in ghee. Freshly prepared cow milk Arjuna ghee possesses good potential to act as free radical scavenger and thus could help in prevention of many free radical related disorders.

Key words: Arjuna, ghee, antioxidant and radical scavenging activity, phytosterol content, oxidative stability.

Abstract

Livestock is the dominant cog of economy of Pakistan and also livelihood supporter fulfiller for the subsistent farmers of country. The country has a great potential and prosperous with dairy animals’ breeds. Unfortunately, farmers are so far away to cash in the actual potential of animals. Non-adoption of improved practices is the major productivity retarding factor. In this regard, present study was conducted in the different areas of Punjab, Pakistan. Data were collected from the 107 livestock farmers. The sample was a blend of landless, illiterate and young, middle aged and small farmers who were immensely dependent on livestock. Data analysis indicated that cattle were the more likely animal among farmers. Farmers were interested in different management practices regarding feeding, breeding and disease management. However, farmers were adopting the only practice which needs no investment and technicality. Farmers were lacking in technical knowledge=2.81) were other constraints compelling farmers to adopt traditional practices. Correlation analysis indicated highly significant association of age, education, land size and annual income with adoption of scientific dairy practices. On the basis of results, it is suggested that the role of livestock extension should be diversified under strict evaluation. Micro credit schemes with cooperation of government may also boost the adoption. It is also inferred that international organization may also start some projects keeping in mind the ultimate potential of Pakistan dairy sector.

Key words: Livestock, dairy farming, adoption, Punjab.
