“…Dietary supplementation of neem leaves has been reported to negatively affect the growth performance of broiler chickens (i.e., body weight gain and feed conversion ratio) ( Bonsu et al , 2012 ; Ubua et al , 2019 ). Alternatively, one study demonstrated that dietary supplementation with 0.6% water extract of neem leaves did not affect the growth performance or carcass weight of broiler chickens ( Shaahu et al , 2020 ).…”

“…The leaves also contain relatively high fat and mineral content ( Esonu et al , 2005 ; Bonsu et al , 2012 ). In chickens, feeding diets containing 2.5%–7.5 % of neem leaves negatively affected growth performance because of the high crude fiber content ( Udedibie and Opara, 1998 ; Bonsu et al , 2012 ; Ubua et al , 2019 ). Nnenna and Okey (2013) reported that dried neem leaf extract (DNE) could be added to chicken feed without negatively affecting the growth performance or altering the biochemical parameters in the blood.…”

This study was conducted to evaluate the effects of dietary supplementation of dried neem (Azadirachta indica) leaf extract (DNE) on lipid peroxidation and the expression of genes encoding mRNAs in antioxidant enzymes in the pectoralis major muscle of chickens. A total of 24 male broiler chickens (ROSS308) were divided into three groups (n = 8) at 21 days of age. The control group of chickens was fed a basal diet, and the remaining two groups of chickens were fed a basal diet supplemented with DNE at a concentration of 0.5% or 2.0% until 35 days of age. Growth performance (body weight, weight gain, feed intake, and feed conversion ratio) and tissue weights did not differ among the three groups. The 2.0% DNE-supplemented diet decreased the muscle malondialdehyde content, a marker of lipid peroxidation, and drip loss compared to the control chickens. In addition, the expression of genes encoding mRNAs of antioxidant enzymes (i.e., Cu/Zn-superoxide dismutase, Mn-superoxide dismutase, glutathione peroxidase 7, and catalase) were higher in the pectoralis major muscle of chickens fed the 2.0% DNE-supplemented diet than in the control chickens.Therefore, DNE supplementation increased the expression of genes encoding mRNAs in antioxidant enzymes and reduced lipid peroxidation and drip loss in the pectoralis major muscle of broiler chickens.

“…The improved growth performance of broilers on diets with DGRC compared to those on control diets (Table 5) observed in the present study is in agreement with the the results of Esonu et al (2006) who reported a general increase in growth rates of birds as rumen contents were increased in the diets. However, the significant decrease in average daily feed intake (ADFI) of birds with increase in DGRC in the diets may be attributed to increase in dietary fiber content (Ubua et al, 2019) and more so, to the unpleasant smell of rumen contents. Dietary fiber limits feed intake (FI) more especially in young birds because their gastrointestinal tract (GIT) cannot digest fiber more easily (Ubua et al, 2019).…”

Dietary fiber limits feed intake (FI) more especially in young birds because their gastrointestinal tract (GIT) cannot digest fiber more easily (Ubua et al, 2019). As the level of DGRC increased in the diets, this could have led to a commensurate increase of unpleasant smell in the diets which could have eventually translated into reduced feed intake by the birds (Odonsi, 2003;Said et al, 2015).…”

The study investigated the use of dried goat rumen contents (DGRC) on growth performance of broiler chickens. Rumen contents were obtained from goats immediately after slaughter during the wet season, sundried, milled and incorporated in experimental diets at levels of 0, 5 and 10%. The 0% DGRC diet was the control. The experimental diets were formulated on iso-caloric and iso-nitrogenous principles in line with the nutritional requirements for growing broiler birds. Experimental birds were first fed on a common starter broiler diet comprising of 21% CP and 3100 Kcal/kg feed from 0 to 21 days of age; thereafter the birds (21-42 days) were allotted to the experimental treatments in a completely randomized design (CRD) with three replications. A cage with 10 birds was the experimental unit. Experimental diets were offered in the morning and evening, water was provided ad lib. Feed offered and leftovers were weighed daily, and body weight changes were recorded on a weekly basis. The results showed that birds on the 5% diet had significantly (Linear, Quadratic P<0.05) higher final body weights (FBWs), average daily gain (ADG) and better feed conversion ratio (FCR) compared to those o on diets with 0 and 10% DGRC. Apparent and ileal digestibility of nutrients was improved with incorporation of dried goat rumen contents in the diets. Sensory analysis showed that meat from birds on 5% DGRC diet had (P<0.05) more oil content and softer meat across diets. It is concluded that, use of dried goat rumen contents (DGRC) in broiler diets improves growth performance and organoleptic qualities of broiler chicken meat.

“…Neem leaf contains a good amount of protein, minerals and vitamins although it is high in fibre which is characteristic of leaves (Ubua et al, 2019;Akintomide et al, 2021). Kumar et al(2010) reported the relevance of neem could also serve as an antiprotozoal, antifungal and immune modulatory agent (Kale et al, 2003).…”

The study investigated the influence of neem leaf meal (NLM) with or without enzyme supplementation on carcass and meat qualities of broiler chickens. Two hundred and eighty eight (288) broiler chickens were randomly allocated to diets in which NLM was included at 0, 1.5, 3 and 5% with and without enzyme supplementation to form eight (8) dietary treatments. There were three (3) replicates per treatment and twelve ( 12) birds per replicate in a 4 x 2 factorial arrangement. At the end of the 8 th week, three chickens/ replicate were humanely slaughtered for assessment of carcass and organ characteristics and meat quality of the thigh, chest and drumstick muscles. The results showed that only the relative weights of back (g/kgLW) was significantly influenced (P<0.05) by levels of NLM inclusion. There was also significant (P<0.05) increase in relative weights (g/kgLW) of the liver and pancreas of the broilers with NLM inclusion. Cooking loss, thaw loss and palatability of meat from these chickens were not adversely affected by inclusion of NLM in the diets. Furthermore, the values obtained for moisture contents of the 3 muscles were within acceptable range. In conclusion, inclusion of NLM in broiler finishers' diets up to 5% did not jeopardize the development of carcass and organs, and meat quality of the chickens. Additional effect of enzyme supplementation was not observed in this study.
