Abstract: DELA CRUZ. JOHNCAR A. Cavite State University. Indang. Cavite. April 2005. Evaluation of the Husbandry Practices and Production Performances of the Different Cooperators of the Crocodile Farm Institute (CFI) in Luzon. Adviser: Rezin C. Bahia, DVM. MS. This study was conducted to compare and evaluate the present crocodile husbandry practices and production performances of the different cooperators of the Crocodile Farm Institute (CFI). The cooperators studied were from Lipa City, Batangas; Trece Martires. Cavite and Teresa. Rizal and were designated as Farm A, Farm B and Farm C, respectively. These farms utilized only one species of crocodile, the Crocodylus porosus. All cooperators were privately-owned and started operations in January 2000. The farms were principally located on a flat terrain although Farm A and Farm C have in addition 30% and 40% rolling hills, respectively. Housing, flooring and perimeter fencing were principally made of concrete. Vegetation was found in or within the vicinity of these farms. Chicken remained to be the staple food source of the crocodiles as these farms also have poultry businesses. Only Farm C employed the services of a veterinarian although all the farms followed a fixed medication program. Results of the Analysis of Variance (ANOVA) showed highly significant differences (p < 0.01) on the Average Daily Gain (ADG) and Average Daily Gain in Length (ADL) among the three farms. However, there were no significant differences (p > 0.05) on the Feed Conversion Rate (FCR) of the three farms evaluated. Moreover, results showed that the ADG of Farm A (0.0206 kg./day), Farm B (0.0248 kg/day) and Farm C (0.0448 kg/day) were significantly higher than the ADG of 0.006-0.010 kg/day established by foreign studies. In addition, the ADL (1.088 cm/day) and FCR (28.92%) of Farm C are within the range set by foreign studies of 1.0-2.0 cm/day for the ADL and 27-30% for the FCR, respectively. Results of this study showed that good management and husbandry practices remained to be the most important factor that will guarantee that the production performances are within the normal range. It can also be predicted based on the results of this study that Philippine conditions may be more suitable for rearing crocodiles and that this may demand a different ideal range for ADG, ADL and FCR.
