Mercury deposition/accumulation rates in the vicinity of a lead smelter as recorded by a peat deposit

. Recent findings show that Hg records from peat tend to overestimate historical levels of Hg deposition. Therefore we used the mass loss compensation factor (MLCF) to normalize Hg accumulation rates. These corrected Hg accumulation rates were significantly lower (maximum 129 mg m À2 yr À1 ) and better corresponded to changes in historical smelter emissions, which were highest in the 1960s. The agreement between the corrected Hg accumulation rates in the uppermost peat sections (2-38 mg m À2 yr À1 ) and biomonitoring of atmospheric deposition by mosses in several recent years (4.7-34.4 mg m À2 yr À1 ) shows the usefulness of MLCF application on Hg accumulation in peat archives. However, the MLCF correction was unsuitable for Pb. The recent Pb deposition rates obtained by an independent biomonitoring study using mosses (0.5-127 mg m À2 yr À1 ) were better correlated with net Pb accumulation rates recorded in peat (7-145 mg m À2 yr À1 ) than with corrected rates obtained by the MLCF approach (1-28 mg m À2 yr À1 )

The feed push-up as a factor influencing health of dairy cows

The effect of feed push-up has already been proven in several studies, so this topic can be considered one of the main points that helps improve the health status of dairy cattle. This study aimed to determine how the frequency of feed push-ups influences the health status of udder (mastitis), somatic cell counts, and reproduction. The effect of feed push-up on mastitis, the somatic cell counts, and the conception of dairy cows was evaluated. The feed was pushed-up at a frequency of 2x, 3x, 4x, 5x, and 6x a day for one calendar month. The effect on the number of dairy cows treated with mastitis was insignificant (P ≥ 0.05). The lowest number of cows with mastitis was found when feed was pushed-up five times daily. The effect on the somatic cell counts was insignificantly, too (P ≥ 0.05). The worst milk quality was found in the experimental group, which had a frequency of push-up 5x/day. However, it has been shown that the frequency of food push-up positively affected the conception rate in dairy cows (P < 0.001)

Influences which have effect on the weight of lambs in the age of 100 days of breed texel

The aim of this bachelor thesis was to evaluate chosen influences which have effect on the weight of lambs in the age of 100 days of breed texel. The evaluation was done in 2014 and 283 lambs was include in it. The observed effects were sex, line of ram, the month of birth and litter size of lambs. From the point of view of the influence of sex lambs male achieved the average weight of 33,7 kg in the age of 100 days and female 30,9 kg. From the point of view of the line of ram lambs of line TONDA (38,7 kg) and lambs of line TARTE (34,1 kg) achieved the highest values. The lambs of line TREFLE (30,1 kg) and lambs of line TUTU (30,1 kg) achieved the lowest values. From the point of view of the month of birth the lambs born in June (34,7 kg) and in March (33,1 kg) achieved the highest values. The lambs born in April achieved the lowest values (31 kg). From the point of view of the litter size singles achieved the highest values (34,8 kg). The lambs of triplet achieved the lowest values (29,7 kg). At the observed effects was found that the influence of sex, the month of birth, the line of ram and litter size had an effect on the weight of lambs in the age of 100 days

Vlivy působící na hmotnost jehňat ve 100 dnech u plemene texel

The aim of this diploma thesis is to evaluate the chosen influences which effects the weight of lambs in the age of 100 days of breed texel. The evalution was done from 2013 to 2016 and the basic data set is consisted of 1149 lambs. The observed effects were sex, litter size, month of birth, year of birth, mother's age, father's line, and mother's father line. There was found a statistically highly significant difference in the monitoring of sex influence in male lambs (34,69 kg). A statistically significant difference was found in singles (35,14 kg) when evaluating the influence of litter size. There was found a statistically significant differences between the lambs born in May (36,78 kg) and February (37,29 kg), according to the influence of the month of birth. There is also the influence of the year of birth, a statistically highly significant difference was found between 2016 and 2015. There wasn't found a statistically significant difference in the influence of the mother's age. The influence of the father's line proved a statistically highly significant differences in the TAXI line (36,81 kg) and TAYLOR (37,76 kg). The evaluating of the influence of the mother's father line didn´t show a statistically significant difference in the TRISK line (48,50 kg). There wasn´t found a statistically significant difference in interaction of mother's father line and litter size
