| Dissertation note | The poultry sector is playing a substantial role in agriculture sector of Pakistan. The extensive research in poultry has brought vital changes that accelerated growth and improved FCR. Poultry diets are majorly formulated cost effective for the sustainable poultry industry. For this reason, the main focus is on protein sources which, if maintained to an adequate level with the requirement results in cost effective feeding. In the coming days, main focus of the nutritionists would be on replacement of expensive sources of protein during feed formulation. For this reason, their first choice may be the selection of poorly digestible protein sources such as CM and SFM. These sources are cheaper as compare to the SBM which is imported hence increasing the feed cost. The poorly digestible protein sources, furthermore, in hind gut may be subjected to microbial fermentation, results in formation of nitrogenous products that are not only harmful to birds, but also excreted into litter bedding and generate ammonia, nitrous acid and nitrous oxide, the latter one is a powerful greenhouse gas with an effect about 300 times compared with carbon dioxide. The potential solution to this problem is supplementation of synthetic amino acids in low nutrient density (CP) diets formulated by using cheaper and poorly digestible protein sources. For this reason, a study was designed with the objectives to determine the impact of dLys, on growth performance, ileal digestibility of protein and gut development in broilers fed poorly digestible protein sources (CM and SFM). An experiment with 624 mixed sex 1-d-old broilers (Ross 308) was conducted to test the hypothesis that supplementation of dLys may improves growth performance of the broilers fed poorly digestible protein sources (CM and SFM). The interaction effects of the protein source (CM vs. SFM), CP levels (high vs. low) and dLys (recommended vs. supplemented) were tested in a factorial arrangement of 12 (2 × 2 × 3) dietary treatments and SBM as a control diet was used. The results indicate the birds fed diets DISCUSSION 42 containing CM and SFM supplemented with dLys has significant effect on growth performance in broilers. The results of the study showed that the FI, BWG and FCR for CM and SFM based diets was different during starter and grower phases. The FI and BWG FCR was influenced by CM and SFM based diets. The FI was not influenced by dLys levels during starter phase. The BWG and FCR was improved with supplementation of dLys levels. During starter phase FI and BWG was not influenced by CP levels, however, FCR was improved. The results of the grower phase indicate that FI was significantly influenced by protein sources, CP levels, as well as, by dLys levels. The BWG, similarly, was significantly influenced by protein sources, CP levels, and dLys levels. The FCR during the grower phase was improved by increasing CP level. The FCR was also improved when fed CM based diets. Supplementation of dLys significantly influenced FI and BGW during grower phase. The FCR was also improved with the supplementation of dLys levels. The results indicate that the birds fed dLys supplemented diets had significant effect on ileal digestibility of protein. The results of the study showed that ileal digestibility for protein was not influenced by CP levels. The present study resulted that some of the organs are significantly influenced by dLys levels and CP levels, whereas, other are in influenced by protein sources. Amino acid supplementation showed significant difference on ileal digestibility of protein and gut development in broilers. The negative effect of poorly digestible lysine can be compensated with the supplementation of synthetic amino acids including lysine. CONCLUSIONS Supplementation of dLys above the recommended levels improves the growth performance, ileal digestibility of protein and gut development in broilers fed poorly digestible protein sources (CM and SFM). In conclusion, the negative effects of poorly digestible protein sources in broilers may be ameliorated by supplementation of dLys. |
