![]() The results of the study can improve production indicators and economy in broiler fattening.Įffect of dietary protein level and length of fattening period on dressing percentage and carcass conformation in broiler chickensĭosković, Vladimir Bogosavljević-BoÅ¡ković, Snežana Å krbić, Zdenka Äoković, Radojica Rakonjac, Simeon PetriÄević, Veselin ![]() It follows from our results that the optimum amount of glycerol in feed for poultry is 5%.This study presents an original solution to optimize feed formula by replacing plant oil with glycerol. Feed conversion in chickens in experimental groups was better, being 1.84 kg in the control group and 1.81 kg in the experimental group in females, and 1.73 kg in the control group and 1.72 kg in the experimental group in males. In females, the overall consumption of diets within 38 days of fattening was 3.588 kg in the control group and 4.011 kg in the experimental group, in males, it was 3.915 kg in the control group and 4.366 kg in the experimental group, i.e. At the end of the experiment, the mean weight of chickens in the control group was 2.078 kg, whereas the mean weight of chickens in the experimental group was 2.341 kg. On 15, 32 and 38 day of age chickens of both sexes in the experimental group that were fed with diets containing glycerol showed significantly higher (p ≤ 0.01 mean body weight compared to the control group. Half (50% of the soybean oil in diets used in the experimental groups was replaced with glycerol at a ratio of 1:2. The experiment was performed on 122 one-day-old chickens that were divided based on sex into two control groups (30 females and 31 males and two experimental groups (30 females and 31 males. Glycerol as source of energy in broiler chicken fatteningĭirectory of Open Access Journals (Sweden)įull Text Available The objective of this study was to verify the possibility of replacing soybean oil in a diet with glycerol, and investigate the effect of glycerol on performance indicators and health in broiler chickens.
