137Cs and 40K in some traditional herbal teas collected in the mountain regions of Serbia

Herbal teas are an important part of traditional medicine in Serbia. The objective of the present study was to determine the activity concentrations of 40K and 137Cs in herbal tea, using the gamma spectroscopy method. The samples were collected during the period 2011–2012 in three mountain regions in Western and Central Serbia. The activity concentrations of 40K and 137Cs were found to be in the range of 130–1160 and 0.7–124 Bq kg−1, respectively. The average annual effective dose equivalents from ingestion of 40K and 137Cs for an adult person consuming one cup of herbal tea daily were found to be 588.4–5250.2 nSv for 40K and 4.0–706.1 nSv for 137Cs. Our investigation showed that the herbal teas originating from Maljen, Zlatibor and Tara mountains are radiologically safe for human consumption.

Effect of phytase supplementation on growing pigs performance

Dietary concentrations of phytate are crucial for its anti-nutritive n properties and its negative impact on P availability. The increase of dietary n phytate level is shown to increase endogenous losses of amino acids and n minerals in pigs. The partial availability of the P component of phytate to n simple-stomached species attains importance as the worlds rock phosphate n reserves are not renewable, which could lead to a P supply crisis in the n future. Supplementing phytase is becoming increasingly common as a method to n improve the availability of P in plant ingredients containing high levels of n phytate P. Fourty-eight pigs (Swedish Landrace boars × Dutch landrace sows) n weaned at day 35 with an initial BW of 8.72±0.28 kg were used for a 40-day n weaner performance study. The study was structured as a complete randomized n design to evaluate the response of weaner pigs to four concentrations of n microbial phytase produced by Aspergillus niger: (T1) basal diet; (T2) basal n diet + 1000 FTU/kg; (T3) diet with decreased dicalcium phosphate + 1000 n FTU/kg; and (T4) diet with no dicalcium phosphate + 1000 FTU/kg. Control n group of piglets (T1) has achieved standard body mass while addition of n phytase in meal increased body mass by 6.59% in T2 and 7.52% in T3. Phytase n supplementation prevented decreased body weight gain diets where available n phosphorous level was reduced by 50. The amount of consumed feed per day was n not significantly different. Feed efficiency of T2 and T3 groups was by 3.23% n better and of T4 for 11.29% lower compared to the control group of piglets n (T1). Lower production results achieved by the use of low phosphorous diets n can be avoided to a certain level by the use of microbial phytase. The use of n phytase in pig diet significantly improved phosphorous availability, as well n as of other mineral substances from the phytate complex.

The analysis of forage quality for organic milk production in Fruška Gora region.

As a result of the growing demand for organic products, especially organic milk, the livestock organic production has increased. In this paper botanical and chemical composition of forage for organic diary cow production in Fruska Gora region were analysed. In the mixed hay samples, species from the Poaceae family were classified, according to their nutritive value into the first class. Dominant presence of Dactilys glomerata L. and Poa pratensis was revealed. Lucerne hay was predominantly composed only by one leguminous species Medicago sativa L. Basic nutritive components of mixed and Lucerne hay: crude moisture, crude ash, crude protein, crude fat, crude cellulose, calcium (Ca), magnesium (Mg) phosphorous (P), copper (Cu), iron (Fe), manganese (Mn) and zinc (Zn) were determined. Determined levels of hazardous and noxious substances (mycotoxins, pesticides and heavy metals) in all hay samples were in the range according to regulations. Botanical analysis has confirmed the presence of plants with high yield and of high nutritive value. Chemical analyses of hay samples originating from Fruska Gora has pointed out that the level of crude proteins, cellulose, fats, macro and trace elements can completely satisfy the requirements of animals in organic farming and therefore can present a solid base for further development of organic dairy farming.

Biodiversity and traditional sheep grazing in the South Banat region.

In this paper the capacity for reintroduction of traditional sheep breeds as n key resources for biodiversity conservation systems in HNV farming system of n the South Banat region was analyzed. Taking the vulnerability of the n ecosystem into consideration when creating the optimal grazing system based n on traditional rearing breeds, can contribute to the protection of n biodiversity in the South Banat region. The representatives of Fabaceae, n Poaceae, Lamiaceae, Rosaceae and Apiaceae family were described. Basic n nutritive components of pasture and mixed hay: crude moisture, crude ash, n crude protein, crude fat, crude cellulose, calcium (Ca), magnesium (Mg), n phosphorous (P), copper (Cu), iron (Fe), manganese (Mn) and zinc (Zn) were n measured. Botanical analysis has confirmed the presence of plant diversity, n as well as the nutritive value of sheep pastures. Chemical analyses of n samples pointed out that the levels of crude proteins, cellulose, fats, macro n and trace elements are sufficient to satisfy the requirements of low input n sheep farming system and therefore can be considered a solid base for n reintroduction of autochthonous sheep breeds in the peripheral parts of the n Deliblato Sands area.

The nutritive value of Valjevac grassland - zasavica reservation.

Valjevac pasture of Zasavica reservation with its area of 300 ha presents a n significant area for grazing cattle. In order to evaluate its potential for n livestock production, the botanical and chemical composition of hay in three n different time periods was observed (spring, summer and autumn). The n determined plants species confirmed the richness of Zasavica grasslands, as n well as the presence of dry, moist and forest habitat plants. The analyzed n plants mostly belong to the Poaceae, Fabaceae, Asteraceae and Plantaginaceae n families. Chemical analysis determined that the protein content decreased n (P<0.01) from April (17.22±0.40 %) to October (10.30±0.16 %), and cellulose n content increased (P<0.01) (from 19.07±0.38 % in April to 21.65±0.41 % in n October). The calculated energy density of hay samples ranged from 0.425 n Starch Units (SU) in October, 0.443 SU in April to 0.448 SU in June. The n Valjevac pasture with its numerous plant species is of great importance in n upkeeping biodiversity and also presents a solid base for livestock n production. The determined levels of manganese and copper point out to the n need of copper supplementation especially during the late summer and autumn n periods.

Chemical composition of complete fodder mixes for pig diet during 2007-2009.

Intensive pig breeding implies, among other things, the use of complete mixes n in their diet in correspondence with the animals’ age and purpose. In the n course of a threeyear period (2007-2009) the accredited laboratory of the n Department for Nutrition and Botanics of the Faculty for Veterinary Medicine, n Univerisity of Belgrade, analysed 65 fodder mix samples from the territory of n Serbia intended for the diet of all categories of pigs, namely: 6 samples of n complete mixes for the diet of pregnant sows and gilts, 9 samples of complete n mixes for the diet of nursing sows and boar, 4 samples of complete mixes for n enhanced diet of piglets, 13 samples of complete mixes for piglets in n programme I up to 15 kg, 12 samples of complete mixes for piglets in n programme II from 15-25 kg, 10 samples of complete mixes for growing pigs in n fattening programme I from 25-60 kg, and 11 samples of complete mixes for n pigs in fattening programme II from 60-100 kg. The analyses covered the n contents of the elementary nutritive matter and the obtained results were n compared with the quality conditions prescribed under the Regulations on the n quality of animal feed (Official Gazette of the Republic of Serbia No. n 41/09). It was established that there were certain deviations with regard to n the values presented in the Regulations on the quality of animal feed n (Official Gazette of the Republic of Serbia No. 41/09) in the average protein n content in complete mixes for piglet diet II, 15-25 kg (17.89±1.19%) and in n the mixes for growing pig diet II, 60-100 kg (13.95±0.53%). The established n average fat content was lower in the mixes for enhanced piglet diet (5.99± n 0.72%) and in mixes for piglet diet I, up to 15 kg (4.95±1.41%). A higher n average cellulose content (4.08±0.73%) was established in mixes for enhanced n piglet diet. Furthermore, significant differences from the values prescribed n under the Regulations were established in certain samples. The established n differences in the chemical composition of certain samples of the examined n mixes without a doubt indicate the need for constant and multilevel n monitoring of raw materials and finished products in order to preserve health n and to ensure the best possible utilization of the production potential of n animals.
