leucocephala) by Pulikulam cattle. It is accepted that plant morphology and structure can influence preference
and intake of forages by ruminants (Burns et al., 2001). However, in the present study none of the tree fodders
had thorns and their leaves were equally accessible, suggesting that these factors were not the cause of the
difference. The main cause of the differences in intake was the effective time spent eating each tree fodder.
Hence, it is concluded that tree fodder Agathi (Sesbania grandiflora) is more preferred by Pulikulam Cattle
than (Subabul Leucaena leucocephala) tree fodder.

Introduction

Quails are being reared for meat and egg purpose by farmers. The usage of antibiotic growth promoters in
poultry feed is restricted in many countries because of problems like development of drug-resistant bacteria,
drug residues in the body of the birds, and imbalance of normal microflora. Alternatives to antibiotics such
as enzymes, organic acids, prebiotic, probiotic, phytobiotics etc., are being used in poultry production.
Probiotics are defined as live microbial feed supplement which beneficially affects the host by improving its
