Title: Growth and Water Intake of Boiler Chickens Offered Sucrose in the Drinking Water and the Effect of Nutrient Density Under Hot Arid Conditions.
Author: Selma Yahia Ahmed, Rahama
Abstract: Two experiments were carried out to study the effects of offering 50 g/L solution of sucrose as drinking water on broiler performance during the summer season. Mean maximum and minimum ambient temperatures inside the poultry house were 41.0 and 28.3°, respectively. The experiments were conducted in open-sided poultry houses and broilers were maintained in laying cages. Feed and water were fed ad libitum. In Experiment 1, thirty two one-day old chicks (Hybro) were assigned to four treatments as follows: treatment 1 received sucrose in water continuously throughout the experimental period, treatment 2 was given sucrose solution in the starter period only, treatment 3 was given sucrose solution in the finisher period only and treatment 4 received no sucrose at all. Each treatment was offered to a replicate of eight individually housed birds. The birds were fed standard broiler diet for six weeks. The results revealed significant (P<0.05) improvement in body weight gain, feed conversion ratio and water consumption, in the sucrose supplementation treatments. Birds receiving sucrose ate less feed (P>0.05). Sucrose solution given to birds through out the study (treatment 1) or during the finisher period (treatment 3) resulted in higher values of carcass and non-carcass components characteristics (P<0.05). In Experiment two 24 one-old day chicks (Avian) were fed three different diets for seven weeks. The energy levels of these diets were 3160, 3144 and 2781 kcal/kg for diets A, B and C, respectively. Nutrients density was raised by 10% of all nutrients other than energy in diets B and C. Each diet was fed to 8 individually housed birds, representing a replicate. Sucrose solution (50 g/L) was provided during the finisher period only (last four weeks) for diets B and C. The results of this experiment showed that, higher nutrient density during the starter period improved significantly broiler performance (P<0.05). Birds fed diet "A" had the lowest feed conversion ratio (P<0.05). No significant effect on feed intake was found in all groups. During the finisher period body weight gain, feed conversion ratio water consumption and total energy intake of birds receiving diets “B” and "C" were significantly (P<0.05) better than those of birds consuming diet "A". Feed consumption was similar on diets B and C. However, birds fed diet “C” consumed more feed than those fed diet "A" (P<0.05). The beneficial effects of higher nutrient density and sucrose supplementation water were well illustrated. Feed: water ratio was not affected by sucrose addition. A significantly higher dressing percentage (P<0.05) of carcass was noticed in birds of diets "B" and "C". A significantly lower weight of non carcass components was seen in birds of diet "C".
