Türkiye, Doğu Anadolu Bölgesi ve Muş İlinde Çayır Mera Yem Bitkileri ve Hayvancılığın Bugünkü Durumu

The most important way to reduce feed inputs is to increase the amount of good quality roughage. According to official data of Turkey Statistical Institute (TSI) in 2018, Turkey has 18.6 million bovine animal unit (BAU) livestock existence, and 85 million tons of quality roughage is needed to feed the animal existence. However, total quality roughage production of in the Turkey is 59 million, 10 million from meadow and grassland lands, 18 million from forage crops, 31 million from plant residues. Accordingly, the roughage gap in the country is 26 million tons, this accounts for 30% of the need. The quality roughage deficit is quite above this. The Eastern Anatolia region and Muş province have a great potential in Turkey’s animal husbandry both in terms of the presence of animals and the productivity of the grassland areas. The amount of forage crops produced in the region, where livestock is based on pasture and grassland in general, is also above the average of forage crops produced in Turkey. In order to closure roughage gap in Turkey, it is necessary to obtain higher yields from these areas by improvement and using them in accordance with the technique of those areas. In addition, it is necessary to increase the cultivation areas of forage crops within the field agriculture. By the closure of the shortage of roughage, higher animal production will be achieved, input costs may decrease, and the income level of animal producers will increase and the price of animal products may decrease. The research in Turkey, Eastern Anatolia Region and Mus Province of grassland and forage crops status, deficit and status of roughage, issues were analyzed.

Cow Dung as a Bioremediation Agent to Petroleum Hydrocarbon Contaminated Agricultural Soils

Petroleum derived products are very important as they are energy source and it is prone to accidental spill regularly during the exploration, production, refining, transport and storage. The characteristics of the hydrocarbon content of the petroleum mixture influence the degradability of individual hydrocarbon components; the simpler the hydrocarbon structure the easier its biodegradability and the complex the hydrocarbon structure the harder its biodegradability. Furthermore, the order of biodegradability of hydrocarbon is alkanes > alkenes > alkynes > aromatics. Bioremediation technologies are effective techniques to mitigate many organic and inorganic contaminants such as hydrocarbons, halogenated organic compounds, halogenated organic solvent, non-chlorinated pesticides and herbicides, nitrogen compounds, radionuclides, heavy metals. Bioremediation is having different strategies like an exploration of indigenous microbial populations, bio-stimulation, temperature, soil pH, bio-augmentation, phytoremediation, photo-degradation, phyto-volatilization and phyto-stabilization. Cow dung, excreta of bovine animal is a cheap and easily available bio-resource on earth. Many traditional uses of cow dung are already known in India. Cow dung harbors a diverse group of microorganisms that may be beneficial to humans due to their ability to produce a range of metabolites. Nowadays, there is an increasing research interest in developing the applications of cow dung microorganisms as a bioremediation agent to hydrocarbon contaminated soils. Microorganisms capable of degrading hydrocarbon pollutants have been identified and isolated from cow dung. These organisms include; Micrococcus sp., Bacillus sp., Pseudomonas sp., Enterobacter sp., Proteus kleibsilla, Aspergillus sp., Rhizopus and Penicillium. Therefore, cow dung is an effective, economical and eco-friendly bioremediation agent which can lead to the complete mineralization of hydrocarbon. The post remediation assessment of residual hydrocarbons in contaminated soil can be done with gas chromatographic fingerprinting technique and phytotoxicity bioassay.

The current EU rules on bovine electronic identification systems: state of the art and its further development

Regulation (EC) No 1760/2000 establishes a system for the identification of bovine animals and regulates the mandatory and voluntary labelling of beef and beef products. While bovine ear tags must bear an identifying code, the current European Union (EU) rules do not regulate electronic tags for bovine animal.

Tissue specific differences in insulin receptor characteristics in the mature bovine animal

Insulin is believed to play a key role in the partitioning of nutrients towards fat and protein deposition. The biological effects of insulin are a function of plasma insulin concentration, insulin-receptor concentration and the affinity of the receptor. The number and affinity of insulin receptors on adipocytes differs between genetically lean and obese pigs (Camara and Mourot, 1996) while receptor number, but not affinity, was shown to differ in a variety of bovine muscles (Boge et al., 1995). The objective of the current work was to determine if insulin receptor affinity and number vary between the principal target tissues (i.e. liver, muscle and adipose tissue) in the bovine animal.Five Charolais-cross steers were offered grass silage ad libitum from 18 months of age until slaughter, at 701± 22.9 kg, at a commercial abattoir. Samples of liver [L], of two skeletal muscles [Ml, M3] and of subcutaneous [S], omental [0]and renal [R] fats were taken as soon as possible after slaughter (typically <30min for L, M3, S and O and <45min for Mland R), wrapped and snap frozen in liquid nitrogen prior to storage at -70 °. Insulin receptors were partially purified by solubilising tissues in 1% Triton X-100 for 24 hours at 4 °C followed by centrifugation (100000 x g, lh, 4°) and affinity chromatography of the supernatants on 0.5 ml wheatgerm agglutinin Sepharose 6MB columns. Bound receptors were eluted from the column with 0.3M N-acetyl-D-glucosamine. Receptor binding was assessed using a tracer amount of A-14 125I-insulin (∼35 pM) and increasing concentrations of unlabelled insulin (0-10 μM) in a total volume of 150 μl of pH 7.4 buffer as described by Magri et al (1990).
