There are many reports in the literature about the multifaceted effects of this type of supplementation on the animal organism. Therefore, the aim of the paper is to present the current knowledge of the possible application of nanometal forms in animal nutrition and its potential benefits and threats. The positive effect of nanoparticles used as feed additives has most frequently been reflected in an increase in body weight, higher average daily gain, or improvement of the FCR value. In some cases, however, the effect of nanoparticle addition to diets was indiscernible. The potent antibacterial activity of nanoparticles, especially against Gram-negative bacteria and Gram-positive bacteria, is regarded as a positive effect. In turn, the probability of their toxicity is a potential risk in application thereof. Supplementation of diets with nanometals has been accompanied by patholo...

Pigs were treated with CAP intramuscularly (20 mg/kg b.w. two times every 24 hours). Histomorphometrical and immunohistochemical analyses of small intestine and liver were done. CAP increased the thickness of myenteron and submucosa, and the length of villi; decreased the depth of crypts in the duodenum and jejunum. CAP influenced the Auerbach plexus. A decrease in cell proliferation, an increase in the number of apoptotic cells and T lymphocytes in the CAP-treated pigs were observed. CAP induces hepatotoxicity, neurotoxicity and disturbed intestinal epithelium. It can be concluded that short exposure of pigs to CAP at doses used therapeutically results in disturbed digestion and absorption process in the intestine.

The objective of the present study was to evaluate the effect of the commercial com-plementary feedstuff inclusion into dairy cow nutrition on milk yield and quality. The studies were carried out in a specialized farm for 24 months. The research involved the cows with daily milk production exceeding 20 kg which, having obtained the intended milk yield, were selected succes-sively on the basis of analogues into two treatment groups: control (C) and experimental (E). The experimental factor was a commercial mixture supplement (MS) incorporated into a TMR fed to the E cow group. During the study, the composition, quality and nutritional value of the adminis-tered feedstuffs (every 2 months) as well as the yield, composition and quality of cow milk (once a month) were anal...

The animals from 3 control groups (C-groups) were fed the diets without any additive, whereas 3 other, experimental ones (A-groups) received the diets with additive of glucogenic preparation (450 g per head/day) comprising calcium propionate and loose propylene glycol (1 : 1). In the control groups as well as in the experimental ones, three analogical treatments, differing in concentrate composed of grain species of varying ruminal degradability of starch, i.e. maize (M) – low ruminal degradability, barley and wheat (BW) – high ruminal degradability and marriage of them (MBW) were conducted. Finally, the treatments were: C-M, C-BW, C-MBW, A-M, A-BW, and A-MBW. The rations of all groups based on maize ...

The experiment was conducted on lambs from ewes receiving the MOS prebiotic and the Mi- crobiosan probiotic experiment factor. During the time of rearing, selected hematological and biochemical parameters were marked in lamb blood. The prebiotic introduced in ewes' doses significantly affected (P � 0.05) the red blood cell number growth and the haematocrit value in lamb blood. A positive interaction of prebiotic and the probiotic was found concerning the number of white blood cells and the leukogram. In the examined lambs' plasma (group B and BM) a con- siderable decrease of cholesterol rate as well as an increase of HDL-cholesterol fraction were observed.

The study was carried out on 60 dairy cows which were at their dry-off period at the trial onset. They were divided into 5 groups a control one (K) and four experimental ones, 12 animals each. In respect to the control group, the cows of the experimental groups received diets with GA (calcium propionate and propylene glycol mixture in loose form) at two levels (300 or 450 g/head/d) and during two different periods (4 or 7 weeks). Blood samples were collected 5 times to determine some blood biochemical parameters. The glucogenic supplement elevated the concentration of glucose and decreased beta-hydroxybutyric acid and free fatty acid accumulation in blood plasma. It also reduced aspartate aminotransferase and slightly elevated alkaline phosphatase activity. The best results were achieved when GA was used at the dose of 450 g/head/d for 7 weeks (1 week prior to calving and 6 weeks following it).
