The effect of the haymaking /the traditional haymaking on swath and the two-stages haymaking consisting of the complete fade of swath and the additional drying with the ventilator/ and the silage /fresh green forage, completely dried up forage and fresh with the addition of 0,3% formalin/ on the content of some nitrogenous fractions in Rescue Grass, Timothy, and in the mixture of Rescue Grass with Lucerne and the mixture of Timothy with Common Clover was examined in this work. It was noticed that both silage and haymaking cause the rise in easy soluble nitrogenous fractions. There were from 15% to 40% more of these fractions in green forages than in silages. The addition of 0.3% formalin had no effect on the level of soluble nitrogen. In hay the level of this fraction of nitrogen was lower than in green forages and it depended on the technique of making the silage: there was more of soluble N in the traditional haymaking than in the two-stages haymaking: the difference comprised from 10% to 25% of dissolved N. The silage of the best quality was obtained from the completely dried up plants.

It was determinated the chemical composition, the digestibility of basic alimentary components and collection of red clover and meadow fescue mixtures with following clover participation: 25.50 and 75 %. The green forages from three swathes were subjected to appreciation, beside what utilizing first of it was initiated before the grass heading, but the regrowths were analysed in 6-week spaces. The alimentary components digestibility and receiving of mixtures were determined on milch-cows. The total albumen and raw fibre contents wasn't dependent on mixture composition. The digestibility of alimentary components were comparatively high and for organic matter it comparatively amounted from 69 to 78 %. The digestibility wasn't dependent on mixture composition however it was clearly lower for the first swath.

The aim of the study was to determine the influence of the addition to mixed fodder compouds containing fumaric acid, formic acid, orthophosphoric acid and flavomycin on the productive effects of piglets aged up to 60 days. The experimental was carried out on 30 piglet litters divided into 6 experimental groups. Group I was regarded as a negative control in which the animals did not received any supplements of stimulating activity. The piglets of group II, III, IV, V and VI were given the same fodder with different supplements of ergotropic type, i.e. group II - flavomycin (25 g/t), group III - 1.5% of fumaric acid and flavomycin (25 g/t), IV - 1.5% of fumaric acid, group V - 3% of Cytromix and group VI- 1.5% of Formic-Stabil. It was found that: a) Piglets fed on mixed fodder with the stimulating supplements had higher daily gains of body weight using less fodder per 1 kg of gains compared with animals receiving only the fodder without the supplements; b) The supplements of fumaric acid, formic acid and orthophosphoric acid to fodder designated for piglets aged up to 60 days had a similar influence to other stimulating supplements; c) The best productive effects in piglets aged up to 60 days were observed after administration of supplements in the form of flavonic acid plus fumaric acid; d) Fumaric acid, formic acid, orthophosphoric acid and flavomycin inhibited the development of bacteria and saprophytic fungi in mixed fodder for 6 months.

Celem przeprowadzonych badań było sprawdzenie skuteczności podawanego lochom syntetycznego β-karotenu oraz kwasu foliowego jako stymulatora płodności i plenności loch w doświadczeniu prowadzonym przez cztery kolejne cykle reprodukcyjne. Materiał doświadczalny stanowiło 180 loszek rasy wbpxpbz, przydzielonych do trzech grup doświadczalnych liczących po 60 sztuk. W trzech pierwszych cyklach reprodukcyjnych grupa I (kontrolna) loch otrzymywała standardową mieszankę pasz treściwych. Zwierzętom z grup II i III od pokrycia do 30 dnia ciąży podawano 2 mg kwasu foliowego w 1 kg mieszanki oraz dodatkowo do 14 dnia ciąży 80 mg β-karotenu (gr. II) i 160 mg tego składnika w grupie III. Po 30 dniu ciąży lochy żywiono tą samą mieszanką, co grupę kontrolną. W czwartym cyklu reprodukcji zwierzęta wszystkich grup doświadczenia żywiono identyczną mieszanką, bez stosowania dodatków. W wyniku przeprowadzonych badań stwierdzono, że najbardziej skutecznym modelem żywienia macior ze względu na ilość urodzonych prosiąt było skarmianie przed i 14 dni po pokryciu mieszanką zawierającą dodatek 80 mg β-karotenu i 4 mg kwasu foliowego. Na podstawie uzyskanych wyników stwierdzono, że u loch żywionych mieszankami pasz treściwych zawierających dodatek β-karotenu i kwasu foliowego wzrastała skuteczność krycia oraz liczebność miotów, a zmniejszała się ilość martwych prosiąt w miocie.

Aim passed of investigations was check efficiency of synthetic β-carotene given to sow’s mixture as a stimulator of fecundity and fertility of sows in experiment lasting for four following reproduction cycles. Experimental material determined 180 primiparas sows wbp x pbz allotted to three groups counting 60 animals each. In the first three reproduction cycles sows from control group received standard mixture. Animals from groups II and III from cover to 30th day of pregnancy one gave and 4 mg of folic acid in 1 kg of mixture and additionally to 14th day of pregnancy 80 mg β-carotene (gr. II) and 160 mg of this component in group III. After 30th day of pregnancy animals of all experimental groups fed the same mixture without any addition. In fourth reproduction cycle animals of all groups were feed with the same mixture, without additions. Results of investigation shows, that the most efficient model of nutrition of gilts and sows was feeding from heat to mating and to 14th day of pregnancy mixture containing addition 80 mg β-carotene and 4 mg of folic acid. Obtained results prove, that sows fed with mixtures with addition of p-carotene and folic acid increase mating efficiency, litter size and decrease number of dead -born pigs.

This paper compares several models of protein synthesis in the mammary gland of cows developed by using various statistical models. According to these models, it is possible to predict an increase in the amount of proteins in milk as a result of the addition of proteins or amino acids (AA) to dairy cows’ diet. It is difficult to increase the amount of proteins in milk via nutritional manipulation. In the case of dairy cows, the extra-ruminal addition of AA increases their intake, but an increase in the amount of proteins in milk is not always achieved, since the AA dose often does not include limiting essential amino acids (EAA). An additional factor that complicates protein transformations is AA metabolism in the small intestine and liver, which to a large degree influences the amount and profile of AA transferred to the mammary gland. The utilization rate of AA in the mammary gland depends on their concentration in arterial blood, the rate of blood flow through the udder, the transport process through cellular membranes and the level of amino acid metabolism in the gland. All these processes may be described mathematically by Michaelis-Menten kinetic equations. Nevertheless, the ideal model of protein synthesis in the mammary gland is yet to be developed. Also the role of the most important amino acids for that synthesis is not fully known. Among non-essential amino acids (NEAA), considerable importance is attributed to glutamine and asparagine.

After the addition of fat in rations for cows, a decrease in dry matter intake (DMI) is frequently observed. Stimulation of cholecystokinin release and an increase of the absorption and oxidation of fatty acids in the liver explain the mechanism of this phenomenon. The addition of fat does not reduce the lipolysis of storage fat. Differences in the hypophagic operation of different fats can be explained on the basis of their physical and chemical characteristics and acceptance by cows. The worst tolerated are calcium soaps of palm oil, whereas other fats are consumed by cows quite willingly. Occasionally fat causes the opposite - effect it increases dry matter intake by cows. This occurs when fat is replaced by cereals. DMI and milk yield in cows decreases when increasing the dose of the percentage of unsaturated long-chain fatty acids. This hypophagic effect is explained by either the lowering fiber degradation in the rumen or metabolic regulation of feed intake: unsaturated fatty acids absorbed and oxidized in the liver gives a feeling of satiety and the effect of metabolic fuel or slows intestinal peristalsis. A decreased amount of fat in milk may induce metabolic factors associated with the mammary gland or increase the amount of trans fatty acids in the metabolism of linoleic acid in the rumen. In certain cases, fat supplementation results in reducing the concentration of protein in milk. It decreases the ratio of blood flow through the cow’s udder tissue compared to the amount of milk produced (slower blood flow and a net amount of amino acids per saldo of kilogram of milk secreted is reduced), which results in lower protein content in milk.
