Michal Hulik et al.,(2014) studied effect of mycotoxin sequestering agents added into feed on health, reproduction and milk yield of dairy cattle.

R. Dokovic et al.,(2011) studied effect of zeolite on the chemical composition of milk from Serbian spotted dairy cattle.

Battacone et al., (2009) studied the transfer of aflatoxin M1 in milk of ewes fed diet naturally contaminated by aflatoxins and effect of inclusion of dried yeast culture in the diet.

REVIEW OF LITERATURE

9

AIM: To evaluate proteins, lactose, fat, SNF in milk of buffalo and milk yield up to 45 days in control and treatment groups fed with and without Toxin Binders.

OBJECTIVES: To compare the levels of fat,lactose,SNF,proteins

in milk of buffaloes and milk yield between control and treatment groups.

AIM AND OBJECTIVES

10

Aflatoxins a major concern

Hepatocellular carcinoma, is the third-leading cause of death

SIGNIFICATION OF RESEARCH PROBLEMS SELECTED

11

In addition to health problems aflatoxins affects nutritional value of milk

Role of toxin binders

Aflatoxins cannot be removed through pasteurization

CONCLUSION

Lower milk yield in C & T3 groups and higher in T2 & T1groups

Talc and exal + bentonite proved to be best toxin binders

Protein, SNF and lactose concentration did not vary with the treatments
