Abstract
The current study was conducted to investigate the effects of magnetic treated water (MTW) on performance of adult male baladi goats kept in a special experimental unit at the faculty of veterinary Medicine, Alexandria University.
Goats were classified into two groups. The first group (control group, N=5) received clean fresh tap water during the entire experimental period, while goats of the experimental group (MTW group, N=10) received magnetized water. Animals in both groups were approved as clinically healthy before submission to the experiment and had similar body weights and ages. Moreover, animals received the same daily ration consisting of 0.75 Kg concentrate mixture and 1.25 Kg berseem during the experimental period.
Whole blood, serum as well as ruminal juice samples were collected from each goat in both groups on days zero, 30 and 60 of the experiment. The obtained blood samples were analyzed for complete blood picture (RBCs, WBCs, Hb and platelet count). Serum samples were analyzed for estimation of some biochemical parameters including liver function parameters (Total protein, albumin and globulin, total bilirubin, AST and ALT), renal function parameters (BUN and serum creatinine), redox status (MDA and TAC) and some macro-minerals (Ca, P, Na, K, Mg and Cl) in addition to blood glucose levels. Rumen samples were analyzed for TVFAs, TMC, RCPC, pH and MBRT. Individual goats were weighed at each sampling occasion.
Results were compared statistically between control and MTW groups on days 0, 30 and 60 using T- independent student test.
Improved water quality has been observed to improve nutrient digestibility, dry matter intake and consequently live weight gain of goats. Hemogram of examined goats, revealed significant improvement in values of total erythrocytic, leukocytic and platelets count with non-significantly improved hemoglobin concentration in MTW group.
The serum total proteins, albumin, total globulins, sodium, calcium, and phosphorous levels were significantly increased in MTW group than its level in healthy control goats. On contrary the mean values of, AST, ALT, total bilirubin, BUN and creatinine were significantly reduced in MTW group. While non-significant changes were observed in chloride and magnesium levels.
Additionally, the process of ruminal fermentation was also improved in goats received MTW as reflected in lowered ruminal PH, increased ruminal total microbial count (TMC), rumen ciliated protozoa (RCPr.), increased methylene blue reduction time (MBRT) with non- significantly improved total volatile fatty acids (TVFAs).
MTW altered the redox status where lower levels of MDA and higher levels of TAC were recorded in MTW groups on days 30 and 60 of the experiment indicating favorable effects of MTW on antioxidant system in goat blood.
It is clear that in addition to the statistically significant improvement in most serum vital parameters and rumen function criteria as a result of drinking magnetized water, most of the others vital measures which improved numerically only in the health direction, but this improvement was non- statistically significant, which indicate the possibility of statistical
