Adding Different Types of Commercial Garlic to Drinking Water and Their Effect on Some Productive Traits of Broiler Chickens

Abstract

The experiment was conducted in the broiler hall of the Animal Production Department at the College of Agriculture / Tikrit University for the period from
17/2/2025 to 24/3/2025 to study the effect of using different types of commercial garlic in drinking water and its impact on some productive traits of broiler
chickens. A total of 225 one-day-old Ross 308 broiler chicks were used, placed in floor pens, and divided into five treatments. Each treatment contained three
replicates, and within each replicate, there were fifteen birds. The first treatment was the control group. The birds were fed a ready-made starter diet from the
Middle East factory until 10 days of age. Subsequently, experimental diets mixed in the feed mill of the College of Agriculture / Tikrit University were used. A
grower diet was used from 11 to 24 days of age, and then the diet was switched to a finisher diet, fed from 25 to 35 days of age (Table 1). Feeding was ad libitum.
The experimental materials were added to the drinking water starting from 10 days to 35 days of age. The additions were 500 ml/1000 liters for the second
treatment, 350 ml/1000 liters for the third treatment, 200 ml/1000 liters for the fourth treatment, and 200 g/1000 liters for the fifth treatment, according to the
recommendations of the manufacturing companies, using plastic manual feeders and drinkers.
The results of the statistical analysis showed no significant differences in live body weight at 10 days of age (the beginning of the experiment), nor were there
significant differences in body weight at 24 and 35 days of age. A significant decrease in feed consumption was also observed at 25-35 days of age, as the first
treatment recorded an increase in feed consumption compared to the other treatments, and there was no significant difference between the second treatment and
the control treatment. A significant decrease was also observed in the addition treatments compared to the control treatment in the total amount of feed consumed.
No significant differences were observed at 11-24 days of age in the amount of feed consumed. No significant differences were observed in the rate of weight gain
at any age. The experiment revealed significant differences in feed conversion efficiency during the 11-35 day age period, with a notable improvement observed
in the third, fourth, and fifth treatments compared to the control group. No significant differences were found between these treatments and the second group.
