Concentration of Calcium and Phosphate Serum Following Administration of Zinc in Friesian Holstein Bulls

Minerals play an important role in bulls as they function to form mucles of and maintain the quality of sperm. Zn mineral in the diet will also affect the levels of calcium and phosphorus in the blood. The objective of this study was to determine the effect of Zn supplementation on the levels of calcium and phosphate serum in Friesian Holstein bulls. This study used ten Friesian Holstein bulls, 16-18 months old and divided into two groups, consisting of five bulls each, i.e. with no added Zn (control) and 60 ppm of Zn supplementation, respectively. Zinc was administered daily for four months. Blood samples were taken before treatment and after the four- month treatment for the examination of calcium and phosphate levels. The result showed that 60 ppm Zn supplementation was not significantly different (p>0.05) on the blood calcium and phosphate levels. However, the calcium level tends to increase while that of phosphate tends to decrease.

Profil Imunoglobulin-G Serum Kambing Peranakan Etawah Bunting yang Diberi Imbuhan Pakan Mineral Seng (SERUM IMUNOGLOBULIN-G LEVEL ON PREGNANT ETTAWAH CROSSBRED WERE GIVEN ZINC MINERAL)

The objective of this study was to find out the effect of zinc supplementation on the profile of immunoglobulin-G in the pregnant etawah-cross ewes. Fifteen etawah-cross ewes (3-6 years old and 3050 kg body weight) were used in this experiment and they were divided into three groups each of which consisted of 5ewes. The first group (Zn40) received 40 ppm Zn as control, the second group (Zn60) received 60 ppm Zn, and the third group received 80 ppm Zn. Blood samples were collected from jugular vein every two weeks, started at twelve weeks of pregnancy up to eight weeks post partum for immunoglobulin-G analysis. IgG level were analyzed by competitive Enzyme Linked Immunosorbent Assay (ELISA) technique. Results showed that there were no significant difference of immunoglobulin-G level (P>0,05) among the three treatment groups ( Zn40, Zn60, and Zn80). However, IgG level of Zn40 and Zn80 groups tended to decrease during the last staget of pregnancy until two weeks post partum. In conclusion, supplementation of 60 ppm Zn showed higher IgG level than Zn 80 ppm.

Performans Produksi dan Profil Metabolik Darah Domba Garut dan Jonggol yang Diberi Limbah Tauge dan Omega-3 (PRODUCTION PERFORMANCE AND BLOOD METABOLIC PROFILES OF GARUT AND JONGGOL RAMS THAT WAS FED MUNG BEAN SPROUT WASTE AND OMEGA-3)

The research objectives were to evaluate and compare of production performances and blood metabolicprofiles of garut and jonggol rams fed with mung bean sprout waste and omega-3. This research used 24rams aged of 1-2 years, consisted of 12 garut rams weighed of 36,43±1,45 kg (CV=13,87%) and 12 jonggolrams weighed of 23,09±0,57kg (CV=8,64%). Research used Completely Randomized factorial Design(CRD 2x3) with 2 main treatments x 3 factorials and four replications. The first factors as the maintreatments were different breeds of garut and jonggol. The second factors as the factorial treatments werethree different feed percentages which consisted of P0 (40% grass+60% concentrate I), P1 (40% mung beansprouts waste+60% concentrate II), and P2 (40% mung bean sprouts waste+60% concentrate II+omega-3).Data were analyzed by analysis of variance (ANOVA) and proceeded by Duncan Range Test. The resultsshowed that P1 had the highest performance on feed efficiency and average daily gain (ADG) parameters.Blood metabolic test showed that blood total protein, cholesterol, and glucose of all rams were normal. Inconclusion feeding rams with mung bean sprout waste as grass substitution have a positive effect on theperformance of the rams production performance.
