The objective of this study was to compare milk parameters during lactation months on farms using automatic (ALS) and conventional milking systems (PLS). The highest milk yield per cow (30.1 kg) was obtained on 3x PLS farms, whereas cows on 2x PLS farms produced 7.7 kg less milk. Milk yield of the cows on ALS farms (24.8 to 26.3 kg) was between that of 2x PLS 2 and 3x PLS farms. On Robot 1 AL ...

In 2011 the experiment with spring wheat 'Manu' was carried out on the experimental field of the Estonian University of Life Sciences. The experiment was carried out in the soils with different content of organic carbon (Corg): background A with higher Corg content > 1.7% and background B with lower Corg content ≤ 1.7%. Four fertilizing treatment were used: 1) unfertilized, control (K); 2) co ...

Sheep have different nutritional requirements over the production cycle depending, on their life stage. Needs for energy are high at the end of gestation (especially for ewes carrying multiple lambs) and at the beginning of lactation. Ewe body condition score (BCS), production traits and feeding were monitored on three organic sheep farms (Farm A, B and C) during a three year period (2010–201 ...

The majority of the wild feline species are classified as dangerous or particularly dangerous, and that is why, in captivity conditions, performing routine manipulations is impossible without immobilisation. The choice of the immobilization method is made taking into consideration specific conditions, human resources, technology and the equipment available for registering vital physiologic pa ...

Beef cattle farming have expanded rapidly over the last decade in Estonia. The objective of this work was to study the effect of long ageing time on the quality of meat of the Aberdeen Angus cattle. Technological traits were analysed at 14, 28, 35 and 60 days, and chemical parameters at 14 days of ageing. No differences were found between the moisture, ash and protein contents of the muscles, ...

Escherichia coli O157:H7 human infections are mostly associated with consumption of raw or undercooked beef and raw milk. Ruminants, especially cattle are the main reservoir of the pathogen. The main aim of the present study was to evaluate the occurrence of E. coli O157:H7 in cattle dairy farm and beef production level in Estonia. It was found that E. coli O157:H7 is present at both the dairy ...

In actual review, the main morphological properties of the Pseudopodzolic soils and the principles of their dividing into soil species (identified by soil genesis) and varieties (divided on the base of soil texture) are treated. The compiling of actual review is caused by the fact that Pseudopodzolic soil was elected by the Estonian Soil Science Society for the Estonian year 2018 soil. In the ...

During drought chemical elements in a dry fertilizer go into solution in the soil with difficulty and the nutrients are less available to the plant. Foliar fertilization with Tecamin flower®, could compensate for nutrient deficiency due to water deficit. This study was designed to observe the effects of different application rates of foliar application of Tecamin flower® on growth, yield and f ...

Axillary shoot proliferation in in vitro mass propagation of Anoectochilus formosanus was successfully established via selection of different explant types, accessions and culture media to plantlet acclimatization. In the initiation stage, shoot tips and Murashige and Skoog (MS) medium containing 1.5 mg l-1 N6-benzylaminopurine (BAP) and 0.25 mg l-1 α-naphthalene acetic acid (NAA) were determi ...
