ABSTRACTObjective. Evaluate the productivity and composition of fatty acids in chicks fed diets enriched with neem Azadirachta indica A. Juss seed flour. Materials and methods. 80 mixed broiler chicks of Arbor Acres stock and levels 0, 1, 3 and 5% neem seed flour added to a commercial diet were evaluated. 20 experimental units were included in each treatment for five weeks. The consumption and weight gain were recorded, as well as the composition of fatty acids in the fat by means of alkaline transesterification. Data was statistically analyzed by a completely random procedure and the measurements were compared with the Tukey test(p≤0.05). Results. The greatest weight gain, consumption and best feed conversion were found in the treatment that contains 1% neem seed flour. It also produced the increase in the proportion of polyunsaturated fatty acids, especially linoleic acid (C18:2 Omega-6) and eicosapentaenoic acid (C20:5 omega-3), and the proportion of palmitic acid (C16:0). The consumption of feed diminished when 5% of neem flour was added. Conclusions. It was demonstrated that incorporating 1% neem seed flour in the diet of broiler chicks modifies the consumption of fatty acids without harming its productive behavior.RESUMENObjetivo. Evaluar la productividad y composición de ácidos grasos en pollos alimentados con dietas adicionadas con harina de semilla de neem Azadirachta indica A. Juss. Materiales y métodos. Se emplearon 80 pollos mixtos de la estirpe Arbor Acres de engorda y se evaluaron los niveles 0, 1, 3 y 5% de harina de semilla de neem añadidos a una dieta comercial. En cada tratamiento se tuvieron 20 unidades experimentales con una duración de cinco semanas. Se registró el consumo y la ganancia de peso, así como la composición de los ácidos grasos de la grasa mediante transesterificación alcalina. Los datos se analizaron estadísticamente por el procedimiento completamente al azar y las medias se compararon con la prueba de Tukey (p≤ 0.05). Resultados. La mayor ganancia de peso, consumo y la mejor conversión alimenticia correspondió al tratamiento que contenia 1% de harina de semilla de neem. También propició el aumento en la proporción de ácidos grasos poliinsaturados especialmente en el ácido linoleico, (C18:2 omega-6) y en el ácido eicosapentaenoico (C20:5 omega-3), y de manera concomitante se redujo la proporción del ácido palmítico (C16:0). El consumo de alimento disminuyó al adicionar 5% de harina de neem. Conclusiones. Se demostró que la incorporación de 1% de harina de semilla de neem en la dieta de los pollos de engorda modifica la composición de ácidos grasos sin perjudicar su comportamiento productivo.

Background and Aim: Global trend to remove the antibiotic growth promoter (AGP) from animals contributes to the exploration of successful measures to sustain production and reduces the intestinal diseases in the post-AGP era. Plant extracts, therefore, have been used to improve performance and intestinal health. Here, we conducted a study to evaluate the effects of neem (Azadirachta indica) leaf extracts (NLE) as alternatives to AGPs in broiler chickens. Materials and Methods: Sixty day-old broiler chicks were assigned to 12-floor pens, each stocked with five birds and divided into three treatment groups of four pens per treatment. The groups were: Negative control, basal diet without additives; positive control, basal diet with antibiotics and vitamins; and NLE treated group, basal diet supplemented with 0.1% aqua extract of neem leaves. Results: Overall feed intake was significantly (p≤0.05) highest in the positive control. Higher body weight, higher dressing percentage, and lower feed conversion ratio were observed in birds treated with NLE compared to the negative control group (p≤0.05) but not the positive control group (p>0.05). There was no significant variation in hematology between different groups. Furthermore, the economic evaluation indicated that the NLE treatment was found cheaper than control and antibiotic treatment in cost-benefit analysis. Conclusion: We suggest NLE might be a cheaper alternative to antibiotics in broiler production as indicated by improved body weight and feed efficiency.

This study was undertaken to compare the growth performance and nutrient digestibility (energy, protein and amino acid) of broilers fed diets containing only vegetable protein (soybean) with birds that received Pro-EL as protein supplement in their diets. Day-old male broiler chicks (n=60; Cobb 500) were randomly distributed into 2 dietary treatment groups, namely control (T1) and supplemented (T2) diets, with 5 birds per replication in a CRD. Birds had a free access to iso-caloric and iso-nitrogenous starter diets in cages up to 21d.  The results of FI, LW, LWG and FCR of broilers up to 21 days were poorer (P<0.01) on T2 diet than the broilers fed on T1 diet. The ileal nutrient digestibility of GE and CP was identical (P>0.05), but the majority of the AAs digestibility values were influenced (P<0.05; P<0.01) by treatments except for Gly, Thr, Cys, Val, Ile, Leu, and Phe. The digestibility of Asp, His, Arg, Ala, Pro, Ser, Glu, Tyr and Lys was impaired (P<0.05; P<0.01) in the T2 diet compared to T1 diet except for Met, which was improved (P<01) in T2 diet. It can be concluded that the negative response of broilers fed on protein supplemented diet might arise from the reduced nutrient digestibility of the diet.Bang. J. Anim. Sci. 2017. 46 (1): 44-50
