“…These results are contrary with results obtained by Ahmad et al (2007); who reported that HI antibody titer against ND virus was lowest in diets containing 10% CM, whereas, it was highest in those having 15% CM. In another respect, CM at 30% and 60% replacement level did not cause significant effect on the relative weight of lymphoid organs compared to the control which agree with results reported by Ahmed et al (2015) when they fed broilers diets contained 5, 10 and 20% CM. Also, the present results are compatible with the results of Ashnie et al (2015) where, they did not found a significant differences of relative spleen weights among broilers fed diets contained 0, 7.5 and 15% CM while, the broilers fed diets contained 22.5 and 30% CM showed a significant increase of relative weights of spleen compared to the control group which was contrary with our results.…”

This study was conducted to evaluate the effects of replacing soybean meal (SBM) protein with canola meal (CM) protein on productive performance, nutrient digestibility, immune response, lymphoid organs, blood parameters, carcass fatty acids and cecum microbiota of broilers. A total of 160 one d-old Arbor Acres broiler chicks were randomly allocated to 4 dietary treatments of 5 replicates, where, CM protein replaced SBM protein at 0, 30, 60, and 90% for a 39 days feeding trial. The results showed no significant differences in productive performance parameters among control, 30% and 60% treatment groups, while, at 90% replacement level, all values decreased (P < 0.0001) all over the experimental period. The 90% replacement group showed depression of crude protein (P < 0.001) and crude fiber (P < 0.001) digestibility and spleen relative weight (P = 0.0386) with increase of thymus (P = 0.0555), bursa (P = 0.0334) and thyroid relative weight (P = 0.0276) as well as thyroid hormones (P = 0.0034, 0339) for T3, T4, respectively, while, there were no significant differences among control, 30% and 60% treatment groups for those criteria. However, CM levels had no effect on serum haemagglutination inhibition (HI) titer against Newcastle disease. CM significantly decreased serum cholesterol content (P = 0.0002) while increased HDL (P = 0.0532), compared to the control. CM levels showed an increase in carcass meat content of unsaturated fatty acids content (P < 0.0001) as the replacement level gradually increased. Erucic acid did not detected in carcass. All CM levels decreased cecum content of E. coli (P = 0.0051) while increased that of Lactobacillus (P = 4094). Conclusively, CM can be used safely in broiler diet to replace up to 60% of SBM protein without negative effects on growth and immune response of broilers.

“…Guar meal has been proved as a cheaper feed ingredient than cotton seed cake (CSC) and replacing CSC with GM helped in economical ration formulation without any detrimental effects on growth performance in animals (Sharif et al, 2014). Furthermore, enzyme supplementation in GM diets has shown positive effects on dressing percentage in broilers (Ahmed et al, 2015). Studies involving a dietary inclusion of guar in different avian species are summarized in Table 5.…”

| Guar is a very important legume crop in arid areas of Indian sub-continent. Over the world, India is known as the biggest producer of guar bean by contributing around 90% of the total production. Guar meal is defined as a guar gum by-product which has about 450 gram protein per kilogram. In spite having high protein content, guar meal is not known on a commercial scale but it has received substantial attention for animal feedstuffs. Trypsin inhibitors are the main anti-nutritive factor present in guar; however, these can be ameliorated with the uses of enzymes and heat treatment. Fluctuations in market prices of essential feed ingredients motivated poultry nutritionist to look for alternative valuable replacements for certain feeds. Based on the promising findings of guar meal inclusion in diets, it might be an acceptable feed ingredient in poultry feed. Guar meal can be fed up to 100 g/kg diet without adverse effects on poultry performance. Higher level of guar meal at150 g/kg can be detrimental for broiler and layer birds. Because of increasing the availability of guar beans, opportunities have been expanded for using guar meal as a partial alternative for soybean meal (SBM).The inclusion of guar meal in poultry diets canbe maximized by the addition of some feed additives such as β-mannanases. The present review article presents thatnutritional values of protein and amino acids of guar meal is similar to the SBM and seems to be an attractive feed ingredient in the poultry industry.

“…Dietary fibre has been reported to reduce protein and energy digestibility resulting in poor growth performance in chickens (Ahmed et al, 2015 ). Consequently, the potential of CM as a replacement for soybean products in diets of improved poultry species is limited by the negative physiological effects of these ANFs, as reported for quails (Karayagız and Bulbul, 2015 ; Mnisi and Mlambo, 2017 ) and broilers (Gopinger et al, 2014 ; Ahmed et al, 2015 ). A decline in feed intake and body weight was also observed by Woyengo et al ( 2011 ) in broilers fed on diets containing graded levels (0 to 40%) of CM.…”

Partial replacement of soybean products with canola meal in indigenous chicken diets: size of internal organs, carcass characteristics and breast meat quality

et al. 2020

While the use of canola meal ( CM ) as an alternative to soybean meal in broiler diets is well-documented, there is no information on the utility of this valuable by-product for slow-growing indigenous chickens. This study was, therefore, conducted to evaluate the effects of partially replacing soybean products in a chicken grower diet with graded levels of CM on carcass characteristics, relative organ sizes and meat quality in Potchefstroom Koekoek ( PK ) cockerels. A total of 175 PK cockerels (342.6 ± 15.2 g body weight, 5 wk old) were randomly allocated to 25 pens. Five isonitrogenous and isoenergetic grower diets containing 0, 3.75, 6.25, 8.75, and 17.5% of CM were then randomly allocated to the pens (experimental units). After 12 wk of feeding, chickens were slaughtered to measure carcass traits, size of internal organs and meat quality traits. There were no effects of graded levels of CM on carcass weights. Wing weight increased quadratically [ y = 6.27(±0.23) + 0.23 (±0.063) x –0.009 (±0.0003) x 2 ; R 2 = 0.28] in response to incremental levels of dietary CM. Drumstick, vertebrae, liver, and small intestine weights linearly increased ( P < 0.05) in response to incremental levels of dietary CM. Redness (a*), initial meat pH (pH o ), and shear force linearly increased ( P < 0.05) but lightness (L*) and water holding capacity decreased with an increase in CM inclusion levels. However, there were no significant linear and quadratic trends for yellowness (b*), ultimate pH (pH u ), drip loss, and cooking loss in response to incremental levels of CM. There were also significant quadratic trends for mineral contents of the meat with the exception of iron (Fe). It can be concluded that inclusion of CM in place of soybean products had no negative impact on carcass traits, organ size and meat quality traits of indigenous PK chickens.
