This experiment was conducted at the poultry farm, poultry research station, state board of agriculture research, ministry of agriculture to study the effect of supplemental anise seed on broiler diets. A total of 640 of one-day old unsexed broiler chicks (Cobb) were used in this study. They were randomly distributed to four treatments. Anise seeds were supplemented at the levels of 0.2%, 0.4% and 0.6% compared with the control group for 49 days. The results showed: there was a significant (P 〈 0.05) increase in the rate of body weight for the two treatments 0.6% and 0.4% of the anise seeds compared with 0.2% and control treatments, body weight gain take the same direction, like in body weight, the highest treatment was 0.6% followed by treatment 0.4% as well as the feed consumption has increased in these treatments than in 0.2% and control treatments, so about feed conversion ratio the treatment 0.6% of the anise seeds recorded the best feed conversion ratio compared with other treatments. Significant decreased in mortality and significant increased in production index by increasing the level of anise seeds in feed. Dressing percentage increased significantly for all treatments using anise seeds and treatment 0.6% recorded highest dressing percentage, from the other hand percentage of abdominal fat decreased significantly by increasing anise seed levels and no significant difference in the percentages of liver, gizzard and heart were recorded in this study. About carcass cuts, the weights of primary cuts (thigh, drum stick, breast) relative to body weight recorded significant increase in the treatments using anise seeds at the expense of secondary cuts (neck, wings, back). There was a significant decline (P 〈 0.05) for total bacterial (E. coli and Staphylococci) in small intestine in all level of anise seeds (0.2%, 0.4%, 0.6%) in ration while the decline of two types of bacteria in colon recorded in 0.4% and 0.6% treatments compared with 0.2~/0 and control treatments. Conclude from this study the possibility of using anise seeds at all levels used in the experiment and the best level that can be used to get the best performance of the positive results of broiler chickens is 0.6%. 展开更多

A study was conducted to determine the effects of dietary digestible amino acids of feedstuffs and true metabolizable energy corrected for nitrogen on broiler breeder performance in 50 weeks to 64 weeks of age. 140 females and 20 males broiler breeders in 4 treatments with 5 replicates (7 females with a male) were used in the form of a completely randomized trial design 2 ~ 2 factorial. Four experimental diets were formulation based on two factors, first factor was included, two types of Apparent and True Metabolizable Energy corrected for Nitrogen (AMEn and TMEn) and the second factor was included, two types of Total Amino Acids (TAA) and Digestible (DAA) of feedstuffs. The result showed that egg weight, egg production (%) and egg mass (g/hen/day) was significantly different which was affected by diets formulation based on energy and interaction between energy and amino acids (P 〈 0.01). Treatment 2 (AMEn + DAA) was at the highest level significantly different (P 〈 0.01) in egg weight 68.97 g, egg production 62.45%, and egg mass 43. i g/hen/day. Hatching eggs were significantly different which was affected by diet formulation based on amino acids. Fertility, hatchability and number of chicks per hen were significant different, that were affected by diet formulation based on energy (P 〈 0.05). Interaction between two factors, were significantly different in two reproductive traits fertility and hatchability (P 〈 0.05). This experiment showed that diet formulation based on AMEn and DAA for broiler breeder was better and significant on performance. 展开更多
