Vplyv prídavku humínových látok u mladých prasiat na rast, parametre exkrécie a mikrobiológiu trusu

The aim of this research was to investigate the influence of dietary humic substances on growth efficiency, faeces indicators, and the bacteriological composition of faeces in piglets. Twenty-four crossbred young pigs (Slovakian White x Landrace) in total were allotted into two groups: the experimental and the control groups. They were fed a diet with humic substances supplemented at 0.5% in the experimental group. In this study, there were no significant differences in the monitored production indicators of piglets. The addition of humic substances increased the dry matter of faeces in the experimental group (P < 0.001). Other indicators in the faeces samples were not significantly affected by dietary treatment. We observed a significant decrease in the counts of coliform bacteria in the faeces (P < 0.05) of the experimental group. The results also showed a tendency to increase the counts of the lactic acid bacteria and a decrease in the counts of the Enterobacteriaceae in the piglets’ experimental group compared to the control group. A decrease in coliform bacteria counts in the faeces of experimental animals showed a positive effect on the microbiota in the intestine. It was concluded that the addition of humic substances to the diet of piglets could have a positive impact on gut flora without having a negative effect on production performance or other fecal characteristics.Cieľom tejto štúdie bolo hodnotiť vplyv humínových látok v krmive na rastovú výkonnosť, vlastnosti trusu a bakteriologické zloženie vzoriek trusu u prasiatok. Celkom 24 krížencov (Slovenská biela × Landrace) bolo rozdelených do dvoch skupín: kontrolná skupina a experimentálna skupina. Boli kŕmené kŕmnou zmesou doplnenou o prídavok humínových látok v množstve 0,5% v experimentálnej skupine. V tejto štúdii neboli zistené signifikantné rozdiely v sledovaných produkčných ukazovateľoch prasiatok (telesná hmotnosť, prírastok telesnej hmotnosti a konverzia krmiva). Suplementácia humínových látok zvýšila obsah sušiny v truse v porovnaní v experimentálnej skupine (P < 0,001). Ostatné sledované parametre vo vzorkách trusu neboli významne ovplyvnené príjmom krmiva s prídavkom humínových látok. Pozorovali sme významný pokles počtu koliformných baktérií vo výkaloch (P < 0,05) experimentálnej skupiny. Výsledky tiež ukázali tendenciu zvyšovania počtu baktérií mliečneho kvasenia a poklesu počtu Enterobacteriaceae v experimentálnej skupine prasiatok v porovnaní s kontrolnou skupinou. Pokles počtu koliformných baktérií vo výkaloch pokusných zvierat preukázal pozitívny vplyv na črevnú mikroflóru. Dospelo sa k záveru, že prídavok humínových látok do krmiva prasiatok by mohol mať pozitívny vplyv na črevnú flóru bez negatívneho vplyvu na produkčné parametre alebo iné vlastnosti trusu

Stanovenie pufračnej kapacity vybraných krmív používaných vo výžive ošípaných

If gastric acidity is to be encouraged, it may be beneficial to eliminate some feed elements from pig starter meals since they bind more acid in the stomach than others. The cereals (wheat, maize, and barley), soybean meal, commercial mineral supplement, and two feed mixtures (one of them with the additive Zeolit) were evaluated. In this study, it was discovered that adding zeolite to the feed mixture had the effect of lowering its initial pH (P<0.001), buffering (P<0.05) and binding capacity (P<0.05). This study aimed to measure the buffering and acid-binding capacity of some ingredients commonly used in growing pig feeds and estimate the coefficient of correlation between crude protein, ash, and the buffering capacity of feed ingredients with significant linear correlation (P<0.05 and P<0.01, respectively). The combined impact of the individual feed mixture components\u27 individual buffering capacities has not been proven.Ak sa má podporiť kyslosť žalúdka, je potrebné obmedziť niektoré zložky krmiva z kŕmnych zmesí pre ošípané, pretože viažu v žalúdku viac kyselín ako iné. V tejto práci boli hodnotené jednotlivé komponenty, ktoré sa bežne využívajú pri výrobe kŕmnych zmesí pre prasatá. Boli použité obilniny (pšenica, kukurica a jačmeň), sójový extrahovaný šrot, komerčný minerálny doplnok a dve kŕmne zmesi (jedna s prídavkom Zeolitu). V tejto štúdii sa zistilo, že pridanie zeolitu do kŕmnej zmesi malo za následok zníženie jej počiatočného pH (P<0,001), pufračnej (P<0,05) a väzbovej kapacity (P<0,05) v porovnaní s kontrolnou kŕmnou zmesou. Pri sledovaní závislosti medzi pufračnou kapacitou a množstvom dusíkatých a minerálnych látok bola zaznamenaná signifikantne zvýšená pufračna aktivita u kŕmnych komponentov s vyšším obsahom dusíkatých a minerálnych látok ako u iných komponentov, ktoré mali nižšie hodnoty dusíkatých a minerálnych látok (P<0,05 resp. P<0,01). Nebol preukázaný kumulatívny efekt pufračných kapacít jednotlivých kŕmnych komponentov tvoriacich kŕmne zmesi. Výsledky poukázali, že analyzovaná pufračná kapacita kŕmnych zmesí je vyššia ako vypočítaná pufračná kapacita na základe pufračných kapacít jednotlivých kŕmnych komponentov tvoriacich kŕmne zmesi
