Dietary effects of different organic acids on growth and nutrient digestibility of broiler

Abstract

An experiment was conducted to determine the effect of organic acids (acetic, butyric, citric and formic acids) on growth and nutrient digestibility of broilers. One hundred fifty (150) day old Hubbard chicks were used. There were five dietary treatments such viz Diet 1 as control contained no organic acid, diets 2, 3, 4, and 5 contained 0.25% acetic, butyric, citric and formic acids, respectively. Each treatment was replicated three times having 10 birds arranged in completely randomized design (CRD). Feed and water were given ad libitum. Feeding of organic acid diets lasted for 7 weeks starting from the second week. At the starter phase, formic acid improved live weight. Feed and water intakes were significantly (P<0.05) reduced by butyric acid. Feed: gain ratio was improved by formic acid. At the finisher phase, live weight was significantly (P<0.05) improved by the acids except butyric acid. Feed intake, daily gain and feed: gain ratio were not significant (P>0.05). Crude protein and ether extracts digestibility were improved by all the organic acids (P<0.05). It is therefore concluded that 0.25% formic acid could be added to broiler diets.Bang. J. Anim.

Effect of Dietary Probiotic and Citric Acid Addition on Broiler Chicks Performance during Fattening Period

“…This change might be because of the expansion in the absorbability of supplements because of good gut conditions including diminished pH of digesta in various section, enhanced gut measure and morphometry, which represents expanded ingestion surface. These results are in concurrence with those detailed by Ndelekwute and Enyenihi (2017) who found that FCR was not significantly influenced for chicks by dietary PB supplementation during growth period.…”

“…1 and 2). These results are corrsistent with Ndelekwute and Enyenihi. (2017) who concluded that digestibility coefficients of nutrients was significantly (P≤0.01) improved by supplementing organic acids mixture to broiler diet as compared to the un-supplemented diet.…”

“…These results are in the line with Ahmad et al (2018) who reported that weight gain was improved due to dietary CA supplementation with 0.3 or 0.5% than the control group. Also, Ndelekwute and Enyenihi (2017) found that organic acids addition to basal broiler diet improved growth parameters as compared with those fed un-supplemented diets.Improvement of weight gain may be attributed to the effect of organic acids onthe integrity of microbial cell membrane, cell macromolecules or meddle with the nutrient transport and energy metabolism causing the bactericidal effect in gut (Rout et al, 2016), or they induced an inhibition of intestinal bacteria which resulting in reduction bacterial competition with the host for available nutrients and reduction toxic bacterial metabolites, resulting in improvement of protein and energy digestibility, thereby improving the weight gain of broiler chicks (Fascina et al, 2012).…”

Apparent nutrient digestibility, gut pH and digesta viscosity of broiler chickens fed acidified water

“…Feed grade enzymes, probiotics, prebiotics, yeast, spices and essential oils, have been reported to increase digestibility in monogastric animals. [9][10][11] Recently, Ndelekwute et al, 12 and Mohammed 13 reported that organic acids enhanced growth performance of broiler chicks. Earlier, Waldroup et al, 14 Patten & Waldroup 15 and Dibner 16 had emphasized the essentials of organic acids in nutrient utilization by broilers.…”

Role of acidifiers in livestock nutrition and health: A review

“…Smulikowska, Czerwiński, Mieczkowska, & Jankowiak, 2008) illustrated increased nitrogen retention in the host supplemented with fat coated organic acids, because of their enhanced bioavailability in the distal digestive tract and the greater epithelial cell proliferation.In broiler chickens,Ndelekwute and Enyenihi (2017) reported that citric and ascorbic acids of lime juice improved digestibility of nutrient at 7 weeks of age of broiler chickens. Also,Ndelekwute et al (2018) found that digestion coefficients of protein, fibre and ether extract were significantly improved by addition of organic acids in drinking water (p < .05).…”
