This study was designed to compare between the effects of subcutaneous injection of ivermectin at the left neck region versus behind the left elbow on the acute behavioural and biochemical responses of sheep, with the aim of selecting the most suitable injection strategy causing the least adverse effects on the animal health and welfare. Twenty-five sheep were assigned to 5 groups: one control group (C, without injection), and two groups injected with 0.9 % NaCl either at neck (SN) or elbow (SE), and two groups injected with ivermectin (IVM) at a dose of 0.2 mg/kg BW either at neck (IN) or elbow (IE). Results reflected that head shaking and neck scratching showed significant increases in the IN group, while standing was significantly lower in the IE group compared to the C group. Pawing was significantly higher in both SE and IE groups compared to the C group. Plasma levels of cortisol, glucose and lactate were significantly increased in both IN and IE groups. There were no obvious changes in the levels of other stress markers among the different treated groups. In conclusions, the magnitude of acute stress reactivity was not significantly different between IVM injections behind the elbow and at the neck region.

Two hundred and twenty eight (228) one day old quails were used to assess the suitability of cassava vinasse meal (CVM) as a replacement for maize at varying inclusion levels of 0.0 %, 5.0 %, 10.0 % and 15.0 %. The birds were fed an adequate starter diet for the first week before being randomly alloted into 4 dietary group of 3 replicate of 19 birds each. The feeding trial lasted for six weeks. The crude protein, crude fibre, ether extract, ash, moisture, nitrogen free extract and metabolizable energy of the dehydrated cassava vinasse were 19.26 %, 7.96 %, 3.72 %, 9.33 %, 5.68 % and 12.17 MJ/kg ME respectively. The results showed that final weight, average daily weight gain and feed conversion ratio were significantly (P < 0.05) influenced as inclusion level of cassava vinasse meal increases. Significant differences were observed on the haematological parameters such as haematocrit and mean corpuscular volume (P < 0.05). The analyzed panelist response on organoleptic parameters showed that tenderness, juiciness and texture were significantly different (P < 0.05) with birds fed 10.0 % CVM having the least values. In conclusion, 10.0 % CVM (21 % replacement for maize) in the diet of quails had no deleterious effect on the feed conversion ratio, haematological parameters and meat acceptability. Moreover, further research could be geared towards the use of exogenous enzymes and the performance of other poultry species including broiler chicken.

The aim of this experiment was to compare selected qualitative parameters in above-ground phytomass of the first Slovak cultivar of Festulolium A et. Gr. cv. Lenor in comparison to earlier registered cultivars Felina and Hykor. The pot experiment was conducted at the Demonstrating and Research base of the Department of Grassland Ecosystems and Forage Crops, Slovak Agricultural University in Nitra (Slovak Republic) with controlled moisture conditions (shelter) in 2017. Content of nitrogen, phosphorus, potassium, calcium, magnesium, crude fibre and water soluble carbohydrates were determined from dry above-ground phytomass of grasses. The significantly highest (P < 0.05) nitrogen content in average of cuts was in above-ground phytomass of Felina (30.3 g/kg) compared to Hykor (25.4 g/kg) and new intergeneric hybrid Lenor (25.0 g/kg). The lowest phosphorus content was found out in hybrid Lenor (3.4 g/kg). In average of three cuts, the lowest concentration of potassium was in new intergeneric hybrid Lenor (5.8 g/kg). The lowest content of calcium was found out in hybrid Lenor (7.0 g/kg). Magnesium concentration ranged from 5.0 g/kg (Hykor) to 6.1 g/kg (Felina). Higher (P < 0.05) fiber content in average of cuts was in above-ground phytomass of Lenor (27.0 %) and Hykor (26.5 %) than Felina (24.0 %). The highest concentration of water soluble carbohydrates was found in Hykor and Lenor (3.5 %).

Between breeders, Chinchilla rabbit is very popular as it has standard body shape and high quality of typically coloured fur. The aim of this study was to analyse quality of Chinchilla rabbit fur. Coat samples were gathered at the National Animal Exhibition in Nitra. We collected samples from three different body areas – those being scapula, back and thigh. Altogether, we obtained 153 samples of different individual animals. We observed different parameters of the fur. Those were – thickness and length of coat, height and width of the undercolour, ticking and height of the guard hair. We found out that average thickness of coat in the examined population was 0.106 mm in the area of scapula; 0.104 mm in the thigh area and 0.113 mm from the back area. Length of the guard hair from area of scapula was 35.8 mm; 37.9 mm in the thigh area and 36.4 mm in the back area. Height of the undercolour was 26.9 mm in the back area, 26.4 mm in area of scapula and 27.6 mm in the area of thighs. Observed width of intermediate colour was 5.1 mm in thigh area; 4.3 mm in back area and 4.8 mm in scapula area. Measured height of terminal black line of hair was 4.7 mm in area of scapula; 5.3 mm in the back area and 5.3 mm in thigh area. The differences among the evaluated body areas were not significant.

In recent years, the importance of biochar application in world´s soils have increased tendency mainly due to its opposite effects. Therefore, the effort of many companies is based on the development of soil amendment which together improve properties and crop productivity in lot of soils. In this short study, we have verified the effectiveness of biochar blended with farmyard manure named Effeco on soil properties and crop yields in different textural soils (1. sandy soil in Dolná Streda and 2. loamy soil in Veľké Uľany). Our results showed that the Effeco increased soil pH in both soils. In sandy soil, the Effeco more significantly affected sorptive parameters and soil organic carbon content than in loamy soil. Water retention in capillary pores after Effeco application in sandy and loamy soils was higher by 22 % and 4 %, respectively compared to control. On the other hand, more significant effect of Effeco application on soil structure was observed in loamy soil. The total crop productions in sandy and loamy soils due to the Effeco application were higher by 82 % and 16 %, respectively, compared to control plots. All in all, we concluded that the effects of biochar blended with farmyard manure differ mainly on soil texture.
