Inclusion of sorghum, millet and cottonseed meal in broiler diets: a meta-analysis of effects on performance.

Batonon-Alavo DI, Umar Faruk M, Lescoat P, Weber GM, Bastianelli D - Animal (2015)

Bottom Line: No effect of the level of substitution of sorghum on feed intake was found; however, growth performance decreased when the level of substitution of corn by sorghum increased.Cottonseed meal was substituted to soybean meal up to 40% and found to increase feed intake while reducing growth performance.An additional work is scheduled to validate these statistical results in vivo and to evaluate the interactions induced with the simultaneous inclusions of sorghum, millet and cottonseed meal in broiler feeding.

ABSTRACT
A meta-analysis was conducted (i) to evaluate broiler response to partial or total substitution of corn by sorghum and millet and (ii) to determine the effect of soybean meal replacement by cottonseed meal in broiler diet. The database included 190 treatments from 29 experiments published from 1990 to 2013. Bird responses to an experimental diet were calculated relative to the control (Experimental-Control), and were submitted to mixed-effect models. Results showed that diets containing millet led to similar performance as the corn-based ones for all parameters, whereas sorghum-based diets decreased growth performance. No major effect of the level of substitution was observed with millet or cottonseed meal. No effect of the level of substitution of sorghum on feed intake was found; however, growth performance decreased when the level of substitution of corn by sorghum increased. Cottonseed meal was substituted to soybean meal up to 40% and found to increase feed intake while reducing growth performance. Young birds were not more sensitive to these ingredients than older birds since there was no negative effect of these ingredients on performance in the starter phase. Results obtained for sorghum pointed out the necessity to find technological improvements that will increase the utilization of these feedstuffs in broiler diet. An additional work is scheduled to validate these statistical results in vivo and to evaluate the interactions induced with the simultaneous inclusions of sorghum, millet and cottonseed meal in broiler feeding.

Mentions: The residuals v. predicted values for all mixed models performed on theresponse to level of substitution are presented in Figure4. No obvious patterns are evident in the plots. However, the slight deviationfrom the solid line (Observed=Predicted) observed in sorghum and millet indicated a smalldifference between observed and predicted values. Better predictions were obtained withcottonseed meal models, since both solid regressions and dashed lines cannot bedistinguished. Despite some largest residuals observed in all ingredients, the lack ofcorrelation (R2≈0) indicated a fairly good prediction of δADFI,δADG and δFCR. Overall, all of the intercepts obtainedfrom the regressions analysis were significantly similar to 0(P>0.10) and the slope, almost (P>0.10), thus confirming the above mentioned results of the levelof substitution on performance.Figure 4
