Abdel-Lattif Coll. of Vet.Med./ Univ. of Al-Qadissia Coll. of Agri./ Univ. of Al-Qadissia AbstractThis study was undertaken to knowledge the chemical composition of some farm animals ( cow,buffalo,sheep and goat ) by using ultrasonic milk analyzer . This method was used first time in our country in the feiled of milk hygiene to determine and comparsion the composition percent of raw milk for farm animals as attempt to protect the health of consumers . 240 raw milk samples for each species of animals included in this study for two different season of year ,first (Novembe 2009 - January 2010) , second from (May – July 2010) . The chemical analysis from milk samples for cows, buffaloes, sheep and goat show the percentage of composition as follow : Fat percentages were 3.7% , 6.8%, 3.4% and 8.7 % ,respectively. Solid non fat compounds (SNF) percentages were 8.6 % , 10.8 % , 9.3% and 8.7 % ,respectively.Protein percentages were 3.3 %,5.9 %, 5.5 % and 3.6 % ,respectively .Lactose percentages were 4.6 % ,4.4 % , 4.3 % and 4.3 % ,respectively . Season of year had a significant effect on percentage of milk composition .
