“…This occurrence reflected higher ammonia absorption occurred in lambs fed urea ration and resulted in its higher plasma urea concentration. This finding agreed with Eryavuz et al (2003) who reported that higher plasma urea concentration was due to high ruminal ammonia as result of rapid hydrolysis of urea to ammonia. Nevertheless, plasma urea concentrations in the present research fall within lower margin of normal physiological range of plasma urea in sheep (2 to 5 mM) as proposed by Sunny et al (2007).…”

A research on dietary inclusion of urea-impregnated zeolite as slow-release urea (SRU) agent had been conducted to reveal its effect on ruminal fermentation characteristics in local lambs. The research used 24 heads of 7-8 mo old of local male lambs with (20.12±2.1 kg BW) designed upon a randomized block design. Treatments consisted of diets contained no urea, urea, zeolite, and urea-impregnated zeolite. The collected data was analyzed with UNIANOVA and Duncan's multiple-range test. Results indicated that feeding no urea, zeolite, or urea-impregnated zeolite ration produced lower ruminal ammonia nitrogen than feeding urea ration (P<0.05). Feeding zeolite ration produced lower ruminal pH than feeding urea ration (P<0.05). Despite total VFAs were similar across the treatments, feeding urea-impregnated zeolite ration produced lower ruminal acetate, acetate to propionate ratio, or methane production than feeding urea ration (P<0.05). Feeding urea ration produced the lowest molar proportion of branch-chained VFAs (P<0.05). Feeding urea ration produced higher plasma urea concentration than feeding no urea ration (2.75 mM vs. 2.16 mM; P<0.05). In conclusion, zeolite or urea-impregnated zeolite as slow-release ammonia or SRU agent was potential in decreasing ruminal ammonia, pH, acetate to propionate ratio, methane, and maintaining low plasma urea within its physiological range.

“…Nevertheless, an insignifi cant decrease in the concentration subsequently occurred in lambs of group A. The statistically signifi cant transitorily higher level of total protein in lambs of ewes receiving 3.1 mg iodine/kg of dietary dry matter was comparable until day 10 a er birth with data of Eryavuz et al (2003) and Ouanes et al (2011).…”

The objective of the study was to evaluate the infl uence of high iodine intake in ewes on haematological and biochemical parameters of the blood of ewes and their lambs. Twelve pregnant ewes of the Sumava sheep breed and their newborn lambs were included in the experiment. Control group (A) consisted of 6 ewes with 7 lambs and experimental group (B) comprised 6 ewes with 6 lambs. The feed ration was enriched with calcium iodate by addition of 3 and 5 mg/kg in group A and group B, respectively. The studied parameters in ewes and lambs were haematocrit value, red blood cell count and haemoglobin concentration in blood, concentration of urea and total proteins, and alkaline phosphatase activity in blood plasma. No diff erences were found out in haematocrit value, red blood cell count, concentration of haemoglobin and total proteins between groups of ewes A and B with their lambs. Urea concentration and alkaline phosphatase activity were higher in ewes of group B and their lambs during the entire experimental period. An increase in the values of urea and alkaline phosphatase in the group of ewes and lambs with higher iodine intake indicates a potential risk of high iodine intake associated with changes in the thyroid activity in ewes and their lambs.

The purpose of this study was to determine the effect of supplementation of sulfur to a diet containing sodium nitrate at a level that would cause chronic nitrate poisoning on some rumen and biochemical parameters in Angora goats. A total of 18 male Angora goats were used. The animals in the control group were fed the basal diet, while the animals were fed experimental concentrate containing 1500 mg/kg sodium nitrate in the nitrate group (N) and experimental concentrate containing 1500 mg/kg sodium nitrate plus 1.8% sodium sulfate in the nitrate-sulfur group (NS) throughout the study, which lasted for 6 months. While there were no differences among groups in live weights, nitrate supplementation to the diet increased the rumen nitrate content and the blood methemoglobin (MetHb) levels and decreased plasma vitamin A and carotene in the N and NS group. The supplementation of sulfur to a diet containing high sodium nitrate alleviated the negative effects of nitrate on the blood MetHb and plasma carotene significantly (P < 0.05). The results of this study suggest that Angora goats can tolerate diets containing the high sodium nitrate levels used in the present study, except for the results in regard to blood MetHb and plasma vitamin A and carotene.
