Tryczki o masie ciała ok. 18 kg żywiono dawką zawierającą 14% białka ogólnego (BO w suchej masie), z którego ok. 25% stanowiło białko poekstrakcyjnej śruty rzepakowej - grupa „R” nasion łubinu żółtego - grupa „Ł” lub ekstruderatu łubinowo-jęczmiennego - grupa „E”. Proces ekstruzji nasion łubinu żółtego wpłynął na zmniejszenie tempa degradacji białka w żwaczu. Jagnięta grupy „E” przyrastały lepiej niż jagnięta grupy ,,E’ (234 vs 186 g, P<0,05). Przyrosty jagniąt grupy „R” (199 g) nie różniły się istotnie od pozostałych (SEM=13,8). Wykorzystanie paszy wynosiło od 4,2 do 5,0 kg suchej masy i od 555 do 729 g BO/kg przyrostu w grupach „E” i ,,E’, odpowiednio (P>0,05). Strawność składników pokarmowych, bilans N (5,1 - 7,0 g/dobę, SEM=0,81) i zawartość allantoiny w moczu (5,2 - 6,4 mmoli/dobę, SEM=0,54) nie różniły się istotnie między grupami.

Young rams of body weights about 18 kg were fed a ration containing 14% crude protein (CP in DM), of which about 25% was rapeseed oilmeal protein (Group „R”), yellow lupine seeds (Group „Ł”), or lupine-barley extrudate protein (Group „E”). Extrusion of yellow lupine led to a decrease in rate of protein degradation in the rumen, Group „E” lambs showed better daily weight gains than Group ,,E’ lambs (234 vs. 186 g, P<0.05). The gains of Group „R” lambs (199 g) did not differ significantly from the others (SEM=13.8). Feed conversion ratio ranged from 4.2 to 5.0 kg DM and from 555 to 729 g CP/kg weight gain in Groups „E” and „Ł”, respectively (P>0.05). Nutrient digestibility, N balance (5.1 - 7.0 g/day, SEM=0.81) and urine allantoin content (5.2 - 6.4 mmole/day, SEM=0.54) did not differ significantly among the groups.

Tannins are water-soluble polyphenols with anti-nutritional properties but when supplemented at a low dose to the diets may exhibit positive effect on ruminants. Owing to great group diversity, tannins demonstrate various biological activities. They form complexes with nutrients and so they are enable to affect digestion processes. Thus, the aim of the study was to examine the effect of two types of tannins on sheep pancreatic enzymes activity. In the experiment 6 ewe of the Coloured Merino breed, fitted with catheters to the common pancreatic-biliary duct and simple cannula to the duodenum were used. Sheep were divided into 3 feeding groups for crossover design (n = 2), and fed control diet (CON) and two experimental diets with dried lingonberry leaves (VVI) or oak cortex (QUE) in a dose of 3 g ∙ d–1 , as a source of condensed and hydrolysable tannins, respectively. Non-significant effect of tannins on pancreatic-biliary juice secretion and its protein concentration was observed. In sheep fed diets with QUE addition lipase activity was increased in comparison to animals receiving VVI. An upward trend in amylase and trypsin activity after tannins addition was also found. Enriching sheep diets with additives containing tannins slightly stimulated pancreas exocrine activity. However, the inhibitory effects of tannins on endogenous protein activity, similar to the digestive enzymes inhibitors action, cannot be excluded. So, further studies on precise defining the mechanism of tannins action on enzymes activity and digestion process in ruminants are necessary

Evaluated was the influence of live cells and metabolites of yeast (Saccharomyces cerevisiae) in the diet on number of ciliates, concentration of volatile fatty acids (VFA) in the rumen and biochemical parameters of blood of heifers. The experiment was carried out on three rumen-fistulated heifers. The animals were fed diet consisting of 88% meadow hay and 12% concentrate. A dose of 10 g of live yeast or their metabolites – 60 g, were introduced into the rumen. The preliminary feeding period of animals lasted three weeks and was followed by sampling of rumen fluid (RF), rumen contents (RC) and blood. The number of protozoa in RC and concentration of VFA in RF as well as total protein, triacylglycerol, total cholesterol, HDL (high density lipoprotein), LDL (low density lipoprotein) and VLDL (very low density lipoprotein) in blood serum were determined. Supplementation with metabolites of yeast significantly increased the number of genus Entodinium compared to animals fed control diet or live cell of yeast. The number of representatives of the genus Diplodinium was similar in heifers fed control diet or metabolites of yeasts and was significantly higher than when the live yeast was applied to the diet. The number of ciliates from genus Ophryoscolex and Dasitricha significantly increased, when heifers were fed diet supplemented with live cells of yeast. Addition of fungal preparations to the diets increased RF pH compared to animals fed control diet. The administration of yeast metabolites to heifers increased molar concentration of acetate and acetale to propionate ratio, but decreased molar proportions of propionate and butyrate. The total protein, triacylglycerol and total cholesterol concentrations decreased significantly when live yeast cells were added comparing to animals fed control diet or metabolites of yeast.
