The revision of honey plants in the regions’ floras and nature objects is regularly made for estimation of melliferous capacity of the territory. The article is devoted to the investigation of the melliferous flora of Northern and North-Western Altai in the area of Altai Territory. The goal of the research was to reveal the botanical composition of authentic honeys. The representativeness of melliferous species among common floristic richness in the studied districts is the following: in Altaiskiy − 56.49 %, Smolenskiy − 60.17 %, Soloneshenskiy − 53.61 %, Charyshskiy − 44.57 %. The examples of the botanical content of samples typical for each of these districts have been shown. In the angelica (djagilevyj) honey from Altajskiy district the maximum content of pollen belongs to the representatives from Apiaceae family 78.86 %. For the angelica (djagilevyj) honeys from surveyed districts the high content of pollen from the families Asteracerae, Brassicaceae, Fabaceae, Rosaceae are typical with different percentage in the samples. The article provides information on examples of wild-growing plant species including relicts, potential melliferous which pollen can be used as “marker” for determination of honey as Altai-origin.

A comparative study was made in 1958 of the visual estimation and hand separation methods of determining botanical composition of two-component forage mixtures. The results indicated that there were positive significant correlations between the per cent legume values obtained by the two methods. The visual estimation method was less variable than the hand separation method and the precision per unit cost was greater. The differences between per cent legume values obtained by the two methods were influenced by the stage of maturity (medium or late hay) of the components and the cut (hay or aftermath). In this study, the difference was significant only in the medium aftermath cut.Individually, three observers showed some inconsistencies between estimates on the medium and late maturity groups and between the hay and aftermath cut. However, by averaging the three estimates to obtain a mean sample, these inconsistencies were minimized.Both methods were more precise in the aftermath pasture cut than in the hay. An additional observer increased precision of the visual estimate more than an additional replicate or sample. The greater precision resulting from additional replicates, samples, or observers increased at a decreasing rate. The number of replicates, samples, and observers required for specific degrees of precision and a specific cost were calculated.The experiment showed that the visual estimation method can be superior to the hand separation method as a means of determining botanical composition.

Research has been conducted for 2 months, namely March to April 2020 aims to find out the type of forage animal feed on the rice fields lora village District Mata Oleo Bombana District Southeast Sulawesi Province. Determination of research locations by purposive sampling with observation variables in the form of forage type of animal feed, botanical composition, weight of fresh materials and capacity of capacity. The results showed the type of fodder forage consists of 10 types namely Cyperus esculentus, Bixa orellana, Cyperus iria L., Fimbristylis moliaceae (L.) Vahl, Digitaria sp., Echinocloa colona, Digitaria setigera, Monochoria vaginalis, Cyperus difformis L. and Desmodium triflorum. Botanical composition with an important value comparison dominated feed forage type Cyperus esculentus (18.72) and the lowest dominance Bixa orellana (1.72). Fresh weight production is 590.40 kg/ha with a capacity of 0.3 UT/ha/month.

This study was carried out at the meadows and pastures in Çolpan village of Van province in 2020. In the study, matter yield, botanical composition, plant covered area, rate of decreaser/increaser/invader species were determined. The Loop method was used to determine the botanical composition. In grassland area were identified 69 species belonging to 17 families. In meadow area were identified 20 species belonging to 6 families. The amount of Poaceae, Fabaceae and other families found in the grassland area were determined as 18.66%, 15.65%, and 65.69%, respectively. In the meadow area, the amount of Poaceae, Fabaceae and other families were determined as 67.50%, 15.0%, and 17.50%, respectively. Artemisia spicigera (4.74%) Taeniatherum caput-medusae (5.0%) Arenaria serpyllifolia (5.0%) Medicago monantha (5.92%) species were the most common species found in the grassland area. Hordeum brevisubulatum (25.5%), Bromus scoparius (16.75%), and Taraxacum androssovii (9.25%) species were the most common species found in the meadow area. According to the ratio of good plants, pasture was classified as poor pasture and meadow was in the moderate meadow class. Grassland and meadow matter yields were found to be 91.4 kg/da and 385.2 kg/da, respectively. In the grassland of Çolpan village, invader species were found to be dense. It was concluded that grassland area should be improved.

Abstract A consortium of European enterprises and research institutions has been engaged in the Feed-Code Project with the aim of addressing the requirements stated in European Union Regulation No. 767/2009, concerning market placement and use of feed of known and ascertained botanical composition. Accordingly, an interlaboratory trial was set up to compare the performance of different assays based either on optical microscope or DNA analysis for the qualitative and quantitative identification of the composition of compound animal feeds. A tubulin-based polymorphism method, on which the Feed-Code platform was developed, provided the most accurate results. The present study highlights the need for the performance of ring trials for the determination of the botanical composition of animal feeds and raises an alarm on the actual status of analytical inaccuracy.
