Some studies on hypocalcemia in pregnant buffaloes in Sharkia province and its control

PART IScmples of blood froD pregnant buffaloes during the different stages of pregnancy and ef-cer parturition were collected and serum was separated. Milk samples after par- turition were also collected cnd samples of diet were ob- tained. The serum aanp Le s lysis for the estimation of Co., P and Mg levels. Cc.lciu111 content of milk and diet was eatimated.serum samples from control non-pregnant apparently norsal buffaloes were ob- tained and Ca , P, and Mg were found to be 10.9.3 (t 0.1897),6.81 (+ 0.2628) aThe effect of age on serum Ca., P, and Mg levels cnd Ca/p ratio was studied. There was a slight decrease in Cclevel at age class 4-6 years with- no variation in serWti inorganic P while there was narked decrease at age class12-14 years in serum P level. At age class 14-16 years there were a sh~rp DROP in Co. level ~nd 0 shnrp rise in Plevel. The Ca/p ratio showed a sharp rise at age class 12- 14 years from 2.1.3 to .3.42 followed by sharp DROP to l.k at the age class 14-16 years.The effect of pregnancy on serum Co., P and Mg levels
