Blood selenium and trace minerals play an important role in animal’s health and production. The aims of this study were to determine selenium effect on blood glutathione peroxidase (GPX) activity, trace minerals and weight gain in lambs. Twelve female Makuei breed were studied for 63 days in groups of control, nanoselenium (NanoSe) and sodium selenite (NaSe). Mean concentrations of GPX, Cu and Fe in selenium supplemented groups were higher than in control group but the differences were not significant. Mean GPX and selenium was significant among the bleeding times, for Cu and Zn significant occasionally while not for weight gain. The percentages of weight gain in groups were 34.20, 38.90 and 36.30, respectively, which was not different. The individual comparison of parameters among groups showed differences for GPX, selenium and Cu. Correlations were observed between weight & Fe, weight & GPX, weight & selenium, Zn & Fe and GPX & selenium in NanoSe group. Weight gain showed negative correlations with Fe and positive correlation with GPX. In conclusion, selenium compounds increased GPX activity and selenium in which it was predominant in NanoSe than in NaSe group. Selenium compounds showed no effects on Cu, Zn and Fe but caused weight gain to increase. NanoSe revealed correlations between weight gain, GPX, Fe and selenium and was preferable to NaSe. Thus, the effect of NanoSe on reducing the oxidative stress and increased weight gain was acceptable and probably an option to NaSe administration in lambs.

Abstract
Lipids in liver wet and dry matter, liver moist and dry matter and their relationships were investigated based on species, sex and age in cows, buffaloes, sheep and goats. Mean percentage of lipids in liver wet and dry matter and liver dry matter in cows were 3.60%, 1.10%, 29.70%, and for buffaloes were ...

Lipids in liver wet and dry matter, liver moist and dry matter and their relationships were investigated based on species, sex and age in cows, buffaloes, sheep and goats. Mean percentage of lipids in liver wet and dry matter and liver dry matter in cows were 3.60%, 1.10%, 29.70%, and for buffaloes were 5.30%, 1.55%, 29.20%, sheep 3.00%, 0.83%, 27.90%, and goats 2.910%, 1.55% and 28.40%, respectively. The highest and lowest percentage of lipids in liver wet and dry matter was observed in buffaloes and sheep, and for the liver dry matter was recorded in cows and sheep, respectively. Analyses showed significant differences in liver parameters among ruminants (p < 0.01). Gender, except for goats, did not affect the animals' liver parameters. In overall 15.00% of buffaloes and 3.50% of cows showed over 10.00% lipids in liver, while none of small ruminants appeared to have over 6.00% lipids in liver. There was no correlation between liver lipid and liver dry matter. In conclusion mean percentage of lipid in liver dry matter in small ruminants was less than large ruminants. Liver dry matter was high in cows and low in sheep. Mean differences in liver parameters was significant, while the age and sex of the animals were not. Liver lipidosis in buffaloes seems greater than in cows, and in small ruminants it was negligible. No correlation was expected between liver parameters. Finally, on the basis of liver dry matter, the liver in ruminants ranked from cows to buffaloes, goats and sheep.
