The effect of linseed oil to pregnant and lactating ewes for rearing lambs
KLÁTIL, Jaroslav
The aim of this thesis was to evaluate the influence of the addition of linseed oil to pregnant and lactating ewes to rearing of lambs. For more conclusive results ewes were divided into groups that received linseed oil (for testing) and the group without the constituents of linseed oil in the diet (control). Effect of linseed oil was demonstrated in ewes blood analysis. Analysis of blood parameters were monitored three - cholesterol, triglycerides and lipase. Physiological levels of cholesterol in sheep is 1,7 mmol.l-1. Before the test was observed in ewes cholesterol levels from 1,6 to 2,2 mmol.l-1 and after the test in the range from 1,3 to 1-9 mmol.l-1. Cholesterol after the test decreased in both the test and the control group. Natural levels of triglycerides in ewes is 0.8 mmol.l-1. In our case, the TAG content was below this threshold. Before the test from 0,18 to 0,22 mmol.l-1 after the test from 0.08 to 0.19 mmol.l-1. In test and control groups after the test content triglycerides decreased. After the test, reducing the content of the lipase in the test group and an increase of the content of the control group. Lambs of control and test group ewes were compared on the following criteria: average daily gain (higher increases should control group lambs), weight in control days, the chemical composition of meat - nitrogen, protein and fats. The normal composition of lamb meat: 21 % crude protein, 4,75 % fat and 1,1 % ash. In our case, the content of the NL test group 22,3 % and 21,8 % of the control group, the fat content of the test group and the control 6,5 % and 5,4 %, ash content in the test group and the control 1,23 % and 1,25 %. Further monitoring criteria: weight in carcass weight (between groups) and analysis of blood (cholesterol, triglycerides and lipase) - no difference between test and control lambs.

The aim of this diploma work is to evaluate levels of reproduction and production indicators, the economics of selected stocks of Suffolk sheep and make recommendations to the owner towards improving current practices.
Blood values of sheep at a defined intake of selenium and iodine
KOCÁBOVÁ, Ivana
The theoretical part is concerned with the functional application of selenium and iodine supplementation methods, risks disproportionate to their income, including changes in biochemical and hematological parameters and evaluation methods of adequate saturation. The practical part analyzes the results of experiments on sheep with a defined content of selenium and iodine in the ration evaluation of selected indicators of the metabolic profile of ewes and their lambs. The results are processed statistically. It reflected the dynamics and interactions of monitored parameters.
