This study aimed to determine the effects of the addition of different doses of Lactobacillus brevis to oat silage on the physical and chemical properties, aerobic stability, in vitro organic matter digestibility, and energy value of the silage. In the study, the treatment groups were oat control (OC), 1x106 (Lb6), 1x108 (Lb8) and 1x109 cfu/kg dry matter (Lb9) L. brevis inoculated oats. Inoculation of L. brevis into oat silage increased the number of lactic acid bacteria and decreased the pH of the silage at the time of opening. This inoculation decreased the organic matter, acid detergent fiber and neutral detergent fiber contents of the silages at opening compared to those of OC, while increasing the dry matter and crude protein contents. The L. brevis inoculation into oat silage decreased the pH values and yeast counts on the fifth day after opening the silages compared to OC, without affecting the amount of CO2 production and mold count. The inoculation did not affect the in vitro organic matter digestibility and metabolizable energy value of silage; but increased the net energy lactation value compared to OC. When the L. brevis doses are evaluated independently, it can be said that 1*108 and 1*109 cfu/kg DM doses contributed more effectively to oat silage, so any of these doses can be preferred.

This study was carried out to determine the effects of different doses (10, 20 and 30%) of sumac shrub leaf substitution instead of corn silage in sheep rations on in vitro gas and methane production, metabolic energy (ME), net energy lactation (NEL) and organic matter digestion degree. Sheep ration consisting of corn silage (20%), alfalfa straw (22.5%), dry meadow grass (20%), and commercial feed (37.5%) constituted the control group. The experimental groups were formed by substituting 10 (S1), 20 (S2) and 30 (S3) percent sumac shrub leaves for corn silage in the control (C) group formed the experimental groups. The effect of sumac shrub leaf substitution on in vitro gas and methane production, metabolic energy, net energy lactation, and organic matter digestion degree was found to be significant. The 24-hour in vitro gas production values of rations ranged between 43.11- 46.77 ml/200 mg DM, methane production values 6.8-7.48 ml, metabolic energy values 8.91-9.41 MJ/kg DM, net energy lactation, 5.59-5.95 MJ/kg DM and organic matter digestion degree values found between 64.25 and 67.61%. As a result, it was determined that increasing doses of sumac shrub leaf substitute reduced gas and methane production. In addition, it was concluded that the data obtained should be supported by determining the microorganism counts, feed consumption amounts, and feed efficiency coefficients with in vivo studies.

This study was carried out to determine the effects of lactic acid bacteria+ enzyme (LAB+E) inoculants on the fermentation characteristics and feed values of silages prepared from alfalfa harvested at three maturity stages. Alfalfa was harvested at the early, middle and late flowering stages. Sil-All (Alltech, UK) were used as LAB+E inoculants. Inoculants were applied to the silages at the rates of 1×105, 5×105 and 1×106 cfu/g levels in 1 liter capacity plastic bags. The bags were stored at 20±2°C under the laboratory conditions. Three bags from each group were sampled for chemical and microbiological analyses on the 45th day after ensiling. The results showed that LAB+E inoculants reduced pH values and ammonia-nitrogen content, whereas increased lactic acid contents and lactobacillus count of alfalfa silages. High doses LAB+E inoculant decreased neutral detergent fiber and acid detergent fiber content, increased in vitro organic matter digestibility and metabolic energy of alfalfa silages. It has been demonstrated that the most effective application dose of LAB+E inoculant to improve fermentation and feed value of alfalfa silage was 1×106 cfu/g, but 1x105 and 5×105 cfu/g level can also be considered as effective dose.

The subject of the analysis was potato production, domestic consumption and foreign trade turnover (export and import) in Poland in 2001-2019. Based on the results of the analyzes, a medium-term projection (for 2025) was defined, covering production, directions of domestic use and foreign trade turnover of potatoes and their products. The analyzed data came from the Central Statistical Office and Institute of Agricultural and Food Economics- National Research Institute. Potato production in Poland in 2001-2019 was characterized by a downward trend. The slower drop in the harvest than in the area was due to the improvement in yield. There were various trends in domestic consumption: a decrease in total potato consumption, in the export of unprocessed potatoes, in processing in distilling and losses in storage, and an increase in food processing and other industrial processing. In foreign trade, an improvement in the positive balance of trade in potato products and a deepening of the negative trade balance in potatoes was observed. The development projection for 2025 shows that the production of potatoes in Poland may amount to 7,250,000- 7,540,000 thousand tonnes, and the demand – 7430 7570 thousand tonnes. The necessary import of fresh potatoes can amount to 30-180 thousand tonnes annually. / Przedmiotem analizy była produkcja ziemniaków, zużycie krajowe i obroty handlu zagranicznego (eksport i import) w Polsce w latach 2001-2019. W oparciu o wyniki analiz określono średniookresową projekcję (na 2025 r.) obejmującą produkcję, kierunki wykorzystania w kraju i obroty handlu zagranicznego ziemniakami i ich przetworami. Analizowane dane pochodziły z GUS oraz IERiGŻ-PIB. Produkcja ziemniaków w Polsce w latach 2001-2019 charakteryzowała się tendencją spadkową. Wolniejszy spadek zbiorów niż powierzchni wynikał z poprawy plonowania. W zużyciu krajowym występowały różnokierunkowe tendencje: spadkowa w spożyciu ziemniaków ogółem, w eksporcie ziemniaków nieprzetworzonych, w przetwórstwie w gorzelnictwie i w stratach w przechowalnictwie oraz wzrostowa w przetwórstwie spożywczym i pozostałym przemysłowym. W handlu zagranicznym zaobserwowano poprawę dodatniego salda handlu przetworami z ziemniaków oraz pogłębianie się ujemnego salda handlu ziemniakami. Z projekcji rozwoju na 2025 r. wynika, że produkcja ziemniaków w Polsce może wynosić 7250- 7540 tys. t, a zapotrzebowanie - 7430-7570 tys. t. Import niezbędny ziemniaków świeżych może wynosić rocznie 30-180 tys. t.

This study was conducted to determine the effects of different doses of Lactobacillus plantarum (LP) inoculation into triticale silage on fermentation, quality, feed value, and aerobic stability. This study used three doses of LP bacteria strains (MF098786 strain) isolated from homemade pickles as inoculants. As LP dose, 1×106, 1×108 and 1×109 cfu/mL levels were used. The LP inoculation was applied by spraying onto by using a sterile injector at 1 mL per 1 kg material. The prepared silages were incubated for 60 d. The treatment groups in the study consisted of triticale control (TC), 1×106 (LP6T), 1×108 (LP8T) and 1×109 cfu/kg DM (LP9T) LP inoculated triticale. The LP inoculation of triticale silage improved silage fermentation, chemical and microbiological properties, silage quality, and feed value, and aerobic stability of the product, regardless of dose application. This application did not change the silage's organic matter, ash, and hemicellulose contents but decreased the crude fiber, neutral detergent fiber, and acid detergent fiber contents. While there was no significant change in color parameters in all silages, a decrease in the ultimate pH value, and improvement in Flieg score and RFV were detected. The LP inoculation into triticale silage increased the number of lactic acid bacteria and decreased the number of yeast in the silages. This application improved the total digestible nutrient and energy values of LP9T silage compared with other silages. When LP doses were evaluated within themselves, it was determined that all doses gave almost similar results in terms of the parameters studied. However, when the data obtained from the research are evaluated as a whole, LP inoculation at the level of 1×109 cfu/mL can be recommended to triticale silage, because of the positive effects of silage on total digestible nutrient, digestible energy, metabolizable energy, and net energy contents.
