Comparative Study Of Cow Milk Constituents Under Different Management Systems

ABSTRACT

The milk constituents of thirty lactating White Fulani cc vs of which five were raised Semi-intensive, sixteen intensively and nine extensively, vere evaluated arid compared. Milk samples (I 00in1) wen coil cted l'oni each animal within one week and analyzed lbr total solids (TS), cru& prc em ( CP), butterfat (BF), solid-not-fat (SN F), total ash, 1,H and gross energy (GE).
