SummaryThe present study was conducted to determine the effect of dietary supplementation of organic acids combined with synergistic components, using a commercial product Lumance™ (Innovad NV, Belgium) containing esterified butyrins, propionic acid and sorbic acid, with medium chain fatty acids (capric, caprylic, and lauric acid) and plant extracts, on the productive performance and mortality of growing broiler chickens. A total of 492, one day old broiler chicks (Ross 308) were randomly allocated to four experimental treatments either with an unsupplemented control or 0.05, 0.1 or 0.15% organic acid mixture in a pelleted corn/soyabean meal diet, which were offered ad libitum until 35 days of age. Results showed that birds in the 0.1% supplemented diet group gave significantly higher (P < 0.05) body weights during the first two weeks of age and increased weight gain during the first three weeks of age. The inclusion had no effect on broiler mortality.

And Performance

A study was carried out to investigate the effects of dietary supplementation of an organic acids mixture and two methionine supplements on intestinal morphology, protein and nucleic acids content, microbial population and performance of broiler chickens. Six hundred unsexed day-old Ross 308 broiler chicks were used in a factorial arrangement (3 × 2) based on a completely randomised design by four replicates with 25 chicks in each. Experimental diets consisted of: 0% organic acid mixture + DL-methionine (Treatment 1), 0% organic acid mixture + Alimet (Treatment 2), 0.5% organic acid mixture + DL-methionine (Treatment 3), 0.5% organic acid mixture + Alimet (Treatment 4), 1% organic acid mixture + DL-methionine (Treatment 5) and 1% organic acid mixture + Alimet (Treatment 6). A significant increase in jejunum mucosal DNA content was found by using 1% of organic acid mixture compared with those by other levels of organic acids at 21 days of age (P < 0.05). Also Treatments 5 and 6 had a higher mucosal DNA content than other treatments (P < 0.05) in a similar period. While at grower stage, the results have shown that protein content, protein/DNA and protein/RNA ratio by 0.5 and 1% of organic acids mixture significantly increased compared with those in the 0% level (P < 0.05). The addition of 1% level of organic acid mixture significantly increased villus height compared with 0 and 0.5% level of organic acid mixture at 21 days of age (P < 0.05). Highest and lowest villus heights were obtained by Treatments 1 and 6 (P < 0.05). Crypt depth increased by 0.5 and 1% of organic acid at 21 and 42 days of age (P < 0.05). Villus surface was significantly increased by 1% of organic acid mixture compared with that by 0% level at 21 days of age. The use of organic acid levels especially 1% resulted in an increase in lactic acid bacteria and decreased Enterobacteriaceae counts in the ileum of broiler chicken (P < 0.05). Better bodyweight and feed conversion ratio were obtained (P < 0.05) by 0.5 and 1% of organic acids mixture, although no response was found in feed intake and mortality in this respect (P > 0.05). The results of this study have shown improved reactions on intestinal morphometrical parameters and microflora atmosphors, by using 1% organic acid mixture. In contrast no differences were found between Alimet and DL-methionine in all tested parameters.

ABSTRACT The objective of this study was to evaluate the effects of probiotics and synbiotics on the performance and Enterobacteriaceae count of broiler chickens. A total of 640 one-day-old male broiler chicks were distributed in a completely randomized design with four treatments and eight replicates with 20 birds each. The treatments were: ration with performance enhancer (zinc bacitracin; positive control); ration without performance enhancer and probiotic/synbiotic (negative control); ration with probiotics; and ration with synbiotics. At 35 days, five birds from each treatment were euthanized and intestinal contents were harvested for determining the Enterobacteriaceae count. The performance data and average colony-forming units (CFUs) transformed as log CFU/g were subjected to analysis of variance and Tukey’s test. The effects of probiotics and synbiotics were observed in the initial phase, with supplemented birds exhibiting comparable weight gain to those supplemented with bacitracin. No effect of the treatment on broiler performance was observed after 42 days. The enterobacterial count was comparable among all experimental treatments. Supplementation with probiotics and synbiotics did not compromise the performance of broilers and did not alter the Enterobacteriaceae count.

This experiment was conducted to investigate the effect of rosemary powder in diet on blood metabolite and performance of broiler chickens. 180 one day broiler chicks were distributed in a completely randomize design with 4 treatments and 3 replicates and 15 bird in each. Experimental treatments were included: Control (without additive), 0.05, 0.1 and 0.2 percent of rosemary in diet. In 42 day of age one bird from each replicate was selected and slaughtering for carcass traits. The results were sowed use of 0.05 percent of rosemary could be significantly increased feed intake of broiler in starter period (p<0.05). Also use of 0.1 percent of rosemary caused to significantly increase broiler body weight gain in overall of rearing period than 0.2 percent group (p<0.05). Use of 0.1 percent rosemary in diet had a significantly  feed conversion ratio (FCR) than T4 (0.2% rosemary). Experimental treatments had no significant effect on carcass traits, except in liver percent weight, which had significantly higher in T2 group (p<0.05). Also experimental treatments had no significant effect on glucose, cholesterol, triglyceride level of broiler chickens in 42 day of age. The results of this experiment showed use of rosemary powder could be improved broiler feed intake in starter period.

Two thousand four hundred male broiler chicks were used in three experiments to evaluate the biological and economic effects of using arsanilic acid as a growth promoter. In two experiments four treatments were (A) control diets (CD); (B) CD plus 99 mg kg−1 arsanilic acid; (C) CD plus drinking water containing arsanilic acid calculated to achieve equivalent exposure to treatment B; and (D) same as treatment C except arsanilic acid concentration reduced by 50%. A third experiment evaluated the dietary addition of arsanilic acid at 0, 33, 66 and 99 mg kg−1. Arsanilic acid supplementation had no significant (P > 0.05) effect on mortality, feed conversion, final live body weights or monetary returns at slaughter age (42 d). Analysis of breast, thigh and liver tissues using method with a sensitivity of 0.02 mg kg−1 showed a significant increase in liver arsenic residues when supplemented diets were fed to slaughter age. Withdrawal of arsanilic acid from diets 7 d prior to slaughter returned the arsenic residues to normal background (control) levels. It is concluded that the use of arsanilic acid at dietary concentrations up to 99 mg kg−1 (the maximum permissible in Canada) was ineffective in improving either the biological or economic performance of broiler chickens.

Body Weights

Four hundred and forty vent-sexed commercial broiler chicks were used in this study. One half of this sample was exposed to common fluorescent light, the other half to a light source that in the spectral composition better approximates daylight characteristics (Vita-lite). Body weights of all birds were measured at weekly intervals. Weight of the body organs was measured on 20 birds randomly taken from each of four possible light source-sex combinations at 14-day intervals. The only significant difference in body weights linked with lighting was found in 2-wk-old chicks. High interactions between sex and lighting at this age revealed a positive effect of Vita-lite on females. In all other age categories, lighting did not affect body weights and did not interact with sex. Regression of body weights on age did not show any differentiation in growth related to the light source. Proportional weight of body organs did not indicate any significant effect of lighting. Birds in cages, illuminated with Vita-lite, when transferred to floor pens showed lower ambulatory activity than their counterparts from normal fluorescent light. Overall mortality during the first 14 days was lower in the Vita-lite group. Frequencies of subjective classifications of birds’ visual appearance showed evident sex × light source interactions only at the age of 14 days.

AbstractThis experiment was conducted to investigate the effects of guanidinoacetic acid (GAA) on productive performance, intestinal morphometric features, blood parameters and energy utilisation in broiler chickens. A total of 390 male broiler chicks (Ross 308) were assigned to six dietary treatments based on a factorial arrangement (2×3) across 1–15 and 15–35-d periods. Experimental treatments consisted of two basal diets with standard (STD; starter: 12·56 MJ/kg and grower: 12·97 MJ/kg) and reduction (LME; starter: 11·93 MJ/kg and grower: 12·33 MJ/kg) of apparent metabolisable energy (AME) requirement of broiler chickens each supplemented with 0, 0·6 and 1·2 g/kg GAA. Supplemental 1·2 g/kg GAA decreased the negative effects of feed energy reduction on weight gain across starter, growing and the entire production phases (P<0·05). Energy retention as fat and total energy retention were increased when birds received LME diets supplemented with 1·2 g/kg GAA (P<0·05). Net energy for production (NEp) and total heat production increased in birds fed LME diets containing 1·2 g/kg GAA (P<0·05). A significant correlation was observed between dietary NEp and weight gain of broilers (r 0·493; P=0·0055), whereas this relationship was not seen with AME. Jejunal villus height and crypt depth were lower in birds fed LME diets (P<0·05). Serum concentration of creatinine increased in broilers fed LME diets either supplemented with 1·2 g/kg GAA or without GAA supplementation (P<0·05). Supplemental GAA improved performance of chickens fed LME diet possibly through enhanced dietary NEp. The NEp could be preferred over the AME to assess response of broiler chickens to dietary GAA supplementation.

Three thousand two hundred male broiler chickens were used to evaluate the efficacy of chlortetracycline (CTC) as a growth promoter when used in compliance with the present maximum feed-supplementation rate permitted in Canada (5.5 mg kg−1). No significant (P > 0.05) improvements in 21- and 42-d live body weights or feed conversion efficiencies were observed, regardless of the method of administration (feed or water). Changes to the sources of dietary calcium and phosphorus in an attempt to circumvent antibiotic inactivation by divalent cations also failed to potentiate any effect of this level of CTC. It is suggested that, if adequate attention is paid to the diet and health of broiler stocks, no further gains will be realized through feed supplementation with 5.5 mg kg−1 CTC.

AbstractA feeding trial was conducted to evaluate the effects of plant extracts derived from Mentha arvensis (MA) and Geranium thunbergii (GT) on broiler performance, carcass yield, digestive organ weights, meat quality and odorous gas emissions from the excreta. A total of 210 one-day-old broiler chicks were randomly assigned to one of the following dietary treatments for five weeks: (1) control, (2) 0.1% MA, (3) 0.05% GT, (4) 0.1% GT and 0.1% mixed preparation with varying ratios such as (5) 0.1% 1MA:1GT, (6) 0.1% 1MA:4GT and (7) 0.1% 4MA:1GT. The weight gain (0–3 weeks) was significantly (P<0.01) increased in response to dietary inclusion of plant extracts; however, no significant differences were observed in breast and thigh meat yield (P>0.05). Additionally, no differences were observed in proventriculus, gizzard, pancreas, small and large intestine weight. When compared with the control group, birds fed plant extracts had the lowest meat TBARS value after 0 and 3 weeks of storage (P<0.05). Moreover, the pH value was significantly lower (P<0.05) in the plant extract supplemented groups at 0 weeks. The faecal H2S emissions were significantly reduced at 0 h and 6 h in all supplemented groups relative to the control (P<0.05). Similarly, NH3 emissions were reduced at 0 h and 6 h for all supplemented groups except the 0.1% 1MA:1GT group (P<0.05). Overall, the results of the present study indicate that plant extracts supplementation can be used to improve performance and meat quality of broiler chickens while reducing the emission of harmful gases from the excreta.

An experiment was conducted to evaluate the effects of Bio strong Forte (BF) on the performance of broiler chickens. The BF is a commercial blend of essential oils and organic acids. Five hundred and forty (540) day old Ross broiler chicks were used in the feeding trial. The birds were randomly distributed into five treatments, each replicated thrice with 36 chicks per replicate. T1 is the control; T2, T3 and T4 had 50, 75 and 100g BF per 100kg feed, respectively while T5 had Oxytetracycline (AGP) 60g/100kg of feed. The five diets were supplied ad libitum to birds for 42 days. Parameters collected were growth performance indices, haematological parameters, liver function indices, and carcass quality. All data were subjected to analysis of variance and significant (P
