Title: OVCHEPOLIAN SHEEP - BRED IN MACEDONIA
Authors: Elena Eftimova; Pacinovski Nikola; Mateva Natasha
Abstract: One of the three local breeds of sheep that is bred and is
under the protection in Macedonia is the Ovchepolian
sheep. The interest of breeders over the past years is
stable, and the number of heads bred from this breed
is increasing. The aim of this research was to give a
picture of the breed itself, some productive features
and its importance.
The data presented in this paper are obtained as
a result of field research within the program for
protection of biodiversity in our country over several
years. They are part of the reports of the Macedonia
Ministry of Agriculture, Forestry and Water Economy.
The average weight of rams is up to 45 kg and of
ewes is up to 35 kg. The color of its hair is often white,
sometimes mixture of white and black, and sometimes
they are completely black. Rams have well-developed
and large horns, while sheep do not have horns or they
have significantly smaller horns. The average lactation
length in this sheep was 6 months, the average
milk lactation was 50 - 60 liters and the average
daily amount of milk was 0.3 liters. The percentage
of fertility was 100 - 110%. Macedonia ratified the
Convention on Biological Diversity in 1997, and in
2004 adopted the first National Biodiversity Strategy
with an action plan. Since then has been started with
an effective protection to stop the loss of biodiversity.
In sheep breeding, the only domestic breed that will
be protected is the Ovchepolian sheep. After the
determination of the farms during 2003, from 2013
until today, this breed is continuously monitored and
financially supported by the state. The financial support
is 9 euros/per head yearly. The annual monitoring
includes 26 - 30 farms, with about 8,000 heads of all
categories, but new herds are also explored, where
it is determined whether they meet the criteria for
financial support. Because the Ovchepolian sheep is
characterized by low productivity that directly affects
the financial stability of stock raiser, endowment of the
same is of particular importance. At the same time, it
makes a significant contribution to the conservation of biodiversity in our country. Until the number of heads
increases from 9,999, when the breed will no longer be
valued as endangered, intensive activity is needed in
its maintenance and appreciation.

Title: Effect of Vegetative Application of Herbicides on the Quality of Silage from Sorghum vulgare var. technicum [Körn.]
Authors: Golubinova Irena; Marinov-Serafimov Plamen; Gjorgovska Natasha; Levkov Vesna
Abstract: On the basis of field experiments carried out during the period 2017 - 2020 in the experimental field of the Institute of Forage Crops –- Pleven, Republic of Bulgaria to establish the phytotoxic effect
of a group of herbicides for postemergence application in broomcorn and the biochemical analysis carried out at the Institute of Animal Science, Skopje, Republic of North Macedonia, a comprehensive assessment of the influence of herbicide selectivity on the quality of broomcorn silage was made. It was found that the physico-biochemical parameters (dry matter content, pH, lactic acid, and butyric acid) in the forage mass are directly related to the fermentation parameters and the quality of the broomcorn silage and are significantly influenced by the selectivity of the
herbicides at the culture. Obtaining silage from broomcorn with good silage qualities can be ensured by using above-ground fresh biomass from the crop with an established phytotoxic effect of no higher than 2.5 score as a result of the application of vegetation herbicides. The silage of above-ground biomass from broomcorn in the growth stage BBCH - 47 with established moderate-strong (EWRS - 4.5 score) to strong phytotoxicity (EWRS - 8.5 score) when applying herbicides, deteriorates the quality of the silage as a result of lowering the content of dry matter and compensatory processes related to reducing the content of lactic acid and increasing the share of acetic and butyric acids.2022-12-01T00:00:00ZInfluence of Pre-Sowing Treatment of Seeds with Siliplant on Initial Growth of Alfalfa (Medicago sativa L.)

Title: Influence of Pre-Sowing Treatment of Seeds with Siliplant on Initial Growth of Alfalfa (Medicago sativa L.) Cultivars
Authors: Marinov-Serafimov Plamen; Golubinova Irena; Cvetanova Galja; Levkov Vesna; Gjorgovska Natasha
Abstract: During the period 2021–2022 in the Institute of Forage Crops - Pleven was established the influence of pre-sowing treatment (priming) of seeds with Siliplant under laboratory conditions on the initial
development of three varieties of alfalfa grown by conventional ("Dara" and "Pleven 6") and SP5A001 biological method. Laboratory seed germination and primary plant development in vitro conditions and their response were evaluated using the complex plant growth index (GI) of the cultivars included in the study.
It was established that the recommended working concentration for pre-sowing treatment of alfalfa seeds with Siliplant for field conditions is in the range of 0.5÷0.6%, determining a complex stimulating effect on the growth of the root, epicotyl, and seedling, respectively and on the initial development of alfalfa in the "sowing-emergence" period. By means of polynomial regression
analysis, equivalence was established between stimulating and/or depressing effect on seedling growth as a result of the pre-sowing treatment of alfalfa seeds with Siliplant, expressed by the plant
development index (GI).2022-12-01T00:00:00ZTHE NUMBER AND COMPOSITION OF YEASTS AND MOULDS DEVELOPING IN BEATEN CHEESE PRODUCED IN INDUSTRIAL CAPACITY

Title: THE NUMBER AND COMPOSITION OF YEASTS AND MOULDS DEVELOPING IN BEATEN CHEESE PRODUCED IN INDUSTRIAL CAPACITY
Authors: Levkov Vesna; Beličovska Daniela; Eftimova Elena
Abstract: A b s t r a c t: The changes in the number end composition of yeasts and moulds during beaten cheese production and ripening were studied. The cheese was prepared in dairy in western part of North Macedonia by using raw cows’ milk and without adding starter culture. The obtained results indicate the presence of yeasts in all stages of cheese preparation. The number of yeasts in milk was in range of 3.62–4.25 log CFU·ml–1 and has increased during dry ripening reaching maximum value of 5.91 log CFU·g-1 in the 3rd day of ripening during the 3rd producing process. The beaten cheese ripening in brine results in decreasing yeasts number reaching value of 3.60 log CFU·g-1. The yeasts isolates were determinate as Kluyveromyces marxianus, Debaryomyces hansenii, Kluyveromyces lactis, Pichia polymorpha, Pichia membranifaciens, Trichosporon pululans, Torulopsis sp., Candida sp. The moulds were not noticed in all stages during beaten cheese making and ripening. They were continuously present during dry ripening till the 15th day of brining. Isolated species were determined as Aspergillus niger, A. oryzae, Mucor mucedo, M. pusilus, Penicillium sp., Trichotecium sp., and Trichoderma viride2022-12-01T00:00:00Z
