Comparative Effects of Garlic or Ginger in the Diets of Broiler Chickens Subjected to Different Feeding Manipulations

The major objective of poultry enterprise is to produce proteins of high quality at minimum cost in the shortest possible time. It is believed that 70 to 75% of total cost on broiler production is incurred on feed. This study composed of two experiments. Experiment investigated the effect of garlic or ginger inclusion in the diets of broiler chickens subjected to different feed access times. A total of 384 unsexed day-old Cobb strain of broiler chickens were used for experiment. The result obtained showed that the main effects of phytobiotics and levels of phytobiotics had a significant (p < 0.05) effect on feed conversion ratio: less feed intake resulted in high body weight gain on the growth performance of the broiler chickens. Inclusion of phytobiotics at 2.5% increased the lymphocytes of the broiler chickens. Low density lipoprotein was significantly (p < 0.05) influenced by the interactive effect of phytobiotics and feed access time in experiment. Increasing its value. Total cholesterol was also increased and significantly (p < 0.05) influenced by inclusion levels of phytobiotics and feed access time in the experiment with birds fed diet containing garlic combined with feed access time of 8 hrs and 12 hrs having the least. Breast percentage of the broiler chickens were significantly (p < 0.05) increased by the inclusion of phytobiotics at 2.5% in the experiment. The study concluded that the inclusion of phytobiotics at 2.5% in restricted birds reduce stress and improved breast meat percentage in carcass of broilers chickens.
