  Background and Objective: A major challenge in broiler breeder management is the nutritional requirement and the effect of feed formulation on breeder performance. Metabolizable energy and crude protein levels are two important nutritional parameters for evaluating poultry feed. The purpose of this study was to evaluate the effect of low-protein and low-energy diets on the performance of Sasso breeders. Materials and Methods: The experiment was performed with 120 Sasso breeders divided into 3 groups (control group, low-protein group and low-energy group) of 40 birds each. Feed intake, body weight, egg weight and egg component weights were recorded weekly. At 35 weeks of age, a total of 600 settable eggs were collected in 7 days and stored at 15°C before incubation. Prior to setting for incubation, eggs were numbered, weighed and assigned to 4 replications of 50 eggs each diet/treatment. Results: Results indicate that breeders of the control diet group exhibited increased body weight (p<0.05) with heavier eggs (p<0.05) and an increased ratio of albumen weight to egg weight (p<0.01) as compared with the groups with the low-energy diet and the low-protein diet (p<0.05). In addition, day-old chicks from eggs of the control group were heavier (p<0.05) than those from eggs of both the low-energy and low-protein diet groups. Conclusion: Low-protein and low-energy diets during the laying period negatively affect the feed intake and feed conversion ratio. These diets also affect the egg weight and ratios of albumen, yolk, shell and chick weight. No significant differences were observed regarding hatchability and blood serum concentration levels of total protein, triglycerides and glucose.

  Background and Objective: Medicinal plants are currently used as alternative to antibiotics growth promoters. However, their positive effect on livestock growth performance, particularly on poultry, depends on the rearing conditions and the birds’ lines. This study investigated the effect of different levels of Moringa oleifera leave meal (MOLM) on performance and serum biochemical parameters of egg-type chicken from one day old to 8 weeks of age. Methodology: A total of 450 days old chicken were randomly assigned to three treatment groups (M0, M1 and M3), 150 birds per treatment group and were respectively fed with diets containing 0, 1 and 3% of Moringa leaf. During experimental period, feed intake, body weight and feed conversion ratio were recorded weekly. At 5 weeks of age, 12 birds per group were slaughtered to collect blood, gizzard, pancreas, heart and liver. Blood serum concentrations in total protein, albumin, uric acid, calcium, magnesium and iron were also determined. Results: Results showed similarity between feed intake, liver relative weight while significant differences (p<0.05) between treated groups and the control one were observed on body weight, daily weight gain, feed conversion ratio and gizzard relative weight. In addition, total protein, albumin, calcium, magnesium and iron levels were significantly increased (p<0.05) in chickens fed MOLM as compared to control. The results also indicate that chickens of control diet group had higher blood uric acid level (p<0.05). However, no significant difference in phosphorus concentration was found between groups. Conclusion: During juvenile growth, MOLM did not affect feed intake, liver relative weight and phosphorus level. The leaves affect body weight, daily weight gain, feed conversion ratio and gizzard relative weight. Significantly differences were observed on total protein, albumin, calcium, iron and magnesium levels.

  Background and Objective: High incubation temperatures accelerate embryonic growth or increase embryonic mortality depending on incubation stage, duration of exposure. The purpose of this study was to evaluate the influence of high incubation temperature on layer chicken embryo. Materials and Methods: A total of 1200 hatching eggs were studied in two different experiments and divided into two groups, control and high temperature group. Eggs of control group were incubated at standard incubation temperature of 37.6°C. Eggs of high temperature groups were incubated at 38.6°C during the first 10 days for experiment 1 or 18 days for experiment 2. During incubation samples of eggs were used to determine the weights of remaining albumen, embryo and yolk sac. Also, hatching events and hatch were monitored every two hours between 19 and 21 day of incubation. Blood samples were collected at 18 day-old embryo, internal pipping stage and at hatch for tri-iodothyronine, thyroxine and corticosterone level determinations. Results: Results suggested that, the embryos incubated at high temperature during the first 10 days used albumen more rapidly with no effect on hatchability. On contrary, embryos incubated at high temperature during the first 18 days reduced significantly albumen utilization after days 13 of incubation with negative effect on hatchability (p<0.05). In addition, high incubation temperature decreased yolk sac weight compared to control groups (p<0.05). In experiment 1, the highest T3 and T4 levels were obtained at internal pipping stage. Conclusion: A temperature increased by 1°C of the standard during the 18 days of incubation is detrimental for embryo development and hatching performance.
