Performance and hematological parameters of broilers fed neem, turmeric,<br>vitamin e and their combinations

Abstract

An experiment was conducted to study the efficiency of inclusion of neem, turmeric, vitamin E and its combinations on performance and hematological parameters for a period of six weeks with 288 day old Raja II broiler chicks. Basal diet was supplemented with Azadirachta indica (Neem 8g/kg feed), Curcuma longa (Turmeric 2g/kg feed) and Vitamin E 0.2g/kg feed) individually and in combination to form eight test diets. Each test diet was fed ad libitum for 42 days. The result of the present stumdy identified no significant difference in body weight of chicks fed with supplemented diets. Whereas, addition of either neem alone or in combination with turmeric and vitamin E induced significant growth depression in birds compared to control birds. Supplementation of neem, turmeric, Vitamin E and their combinations in broiler diets did not exhibit any significant effect on feed intake and feed conversion ratio during all the weeks of age. The percentage livability of birds under different treatments was statistically non-significant. Hematological parameters in broilers revealed that the hemoglobin concentration in neem fed group was significantly (P<0.05) higher (10.5 g/dL) when compared to turmeric fed group (9.85 g/dL), otherwise diet containing turmeric alone recorded lowest value of hemoglobin. Feeding of neem alone and its combination with turmeric and vitamin E increases significantly PCV values as compared to control. The supplementation of turmeric or vitamin E alone to basal diet did not significantly change PCV values.

Effects of Dietary Supplementation with Turmeric Rhizome Extract on Growth Performance, Carcass Characteristics, Antioxidant Capability, and Meat Quality of Wenchang Broiler Chickens

“…The significant biological properties of curcumin render it a potential substitute for antibiotics in livestock feed. A number of studies have been conducted to evaluate the effects of curcumin on the performance of broiler chickens (Suriya et al, 2012;Nayaka et al, 2013;Abou-Elkhair et al, 2014;Olukosi and Dono, 2014); however, the results of these studies have been inconsistent. Keeping in view of the medicinal attributes of C. longa, the purpose of the present study was to evaluate the effects of increasing levels of turmeric rhizome extract (TRE) on performance, carcass characteristics, antioxidant capability, and meat quality of Wenchang broiler chickens.…”

Biochemical studies in experimentally Escherichia coli infected broiler chicken supplemented with neem (Azadirachta indica) leaf extract

“…Neem is the most useful traditional medicine as a source of many therapeutic agents in the Indian culture and grows well in the tropical and semi-tropical countries. It has been shown that neem leaves extract acts as a growth promoter [ 7 ], improve performance and hematological parameters [ 8 ] and immune response [ 9 , 10 ] in broilers. In indigenous system of medicine, every part of the neem tree, viz .…”

“…Increasing heterophils count after administration of birds neem meal recorded previously by (Esonu et al, 2006;Nayaka et al, 2013). Administration of neem aqueous extract combining with vaccination and/or infection induced insignificant increase in heterophils count in compare with groups vaccinated or infected only may be resulted from the possible protection action of neem against heterophils apoptosis as NDV exhibit high-level of apoptosis (Ravindraa et al, 2009).The result of this study agrees with (Obianuju et al, 2015).…”
