The role of dietary supplemental mannan oligosaccharide (MOS) and an essential oil blend (EOB) on performance of laying hens, and susceptibility of egg yolk and hen liver to lipid oxidation were examined. Four hundred and thirty-two 52-week old Lohmann laying hens were divided into three groups and fed a basal diet containing no antioxidant as control (CNT), basal diet plus 1 g/kg MOS and basal diet with 24 mg/kg EOB, for a 10-week experimental period. Supplementation of diet with MOS and EOB improved egg production rate and eggshell weight, but did not influence other performance or egg quality traits. MOS and EOB provided higher antioxidant activity in egg yolk than the control regimen at all storage time periods. EOB also retained the oxidative stability of liver by measuring malondialdehyde (MDA) levels. Liver antioxidant enzymes, including superoxide dismutase (SOD) and glutathion peroxidase (GSH-Px), were higher in birds fed the additives. MOS and EOB tended to increase serum glucose concentration (6.2% and 8.8%, respectively) while they slightly decreased triglycerides (11.0% and 4.8%, respectively) without affecting cholesterol level. Relative weight of pancreas and spleen were not affected by dietary treatments whereas diet supplemented with EOB significantly increased liver weight. The findings of this study suggest that EOB and MOS could act as free radical scavengers that enhance performance and also increase eggshell weight.

Three levels of boron (0, 30, 60 ppm) were supplemented in practical corn-soybean based starter and grower diets, containing either adequate or inadequate Ca or P. A total of 1,800, 1-day-old sexed broiler chicks were assigned to six dietary treatments and fed with the experimental diets for 42 days. Boron improved the overall feed conversion ratio, but increased body weight only at 21 days of age (p<0.01). Boron decreased feed intake in the case of feeding on a diet deficient in Ca and P, and tended to increase feed intake when birds received a diet adequate in Ca and P, signifying significant boron by Ca-P interaction (p<0.01). Mortality was not influenced by boron (p>0.05). Dietary Ca and P deprivation reduced body weight and feed consumption significantly, but did not influence the feed conversion ratio and mortality (p>0.05). Serum Ca level, ALP and ALT activities were not influenced either by dietary Ca and P deficiency or boron supplementation. Serum P content increased with respect to boron at 30 ppm. Bone breakage strength was not affected by dietary variables. Tibia ash, Ca and P were increased in response to the supplementation diet with 30 ppm boron, whereas 60 ppm showed no effect in most cases. Accordingly, the dietary boron supplementation of 30 ppm significantly decreased fecal Ca and P excretion, while there was a numerical decline in the 60 ppm boron as compared to the 0 ppm boron group. Data presented herein indicated that boron, either at the 30 ppm or 60 ppm supplementation level, was effective in conversion of feed to body weight, whereas only boron at 30 ppm contributed to the mineralization of bone thereby augmenting more Ca and P while excreting less through faeces.

The aim of the present experiment was to investigate the effects of oral administration of a live attenuated vaccine (VAC) and an essential oil blend (EOB), either alone or in combination, as a novel anticoccidial strategy for broiler chickens with a mixed Eimeria spp. infection. A total of 624 broiler chicks were randomly assigned to one of six treatments. Two of the groups, only one of which was challenged with coccidiosis, were given a basal diet and served as controls. The other two groups, also infected, were given a basal diet supplemented with monensin sodium (MON, 100 mg/kg) or the EOB (75 mg/kg). Of the remaining two groups, which were infected with coccidiosis, one was vaccinated against coccidiosis (VAC) and the other was both vaccinated and fed a diet with an EOB (VAC+EOB). Birds treated with VAC and VAC+EOB had comparable live performance to MON-fed birds challenged with coccidiosis. Conversely, EOB diet supplementation had negative effects on growth, feed intake and feed conversion ratio throughout the growth period. None of the coccidial control strategies kept pace with the uninfected procedure in terms of performance during the course of the infection. There was no significant difference in mortality among treatments. All of the anticoccidial procedures kept serum infectious bursal disease titers at high levels after coccidial infection and reduced fecal oocyst excretion, with the exception of the MON-based procedure. The results indicate that vaccination against coccidiosis, with or without EOB, demonstrated the same efficacy in promoting recovery from coccidial infection and in reducing oocyst shedding as MON.

The aim of this study was to investigate the effect of diet type, supplementation diet with an essential oil mixture (EOM), and bird gender on the growth performance, carcass yield, internal organ weight, immune response, and small intestine histology of broiler chickens. To do this, a 2×2×2 factorial arrangement was designed. The variables used were: two diet types (based on either wheat or corn), 2 feed additives (with or without EOM), and gender (male or female). EOM supplementation in the diet decreased body weight in corn-fed male birds at Days 21 and 42, but not in those fed the wheat-based diet, signifying a diet × EOM × gender interaction. Cumulative feed intake was not influenced by either the diet type or EOM. The feed conversion ratio was not affected by diet type, whereas EOM improved feed conversion ratio over the 42-day growth period. Feeding birds on wheat decreased the carcass yield while it increased relative small intestine and large intestine weight. Relative weights of liver, bursa fabricius and serum infectious bursal disease (IBD) and Newcastle disease (ND) titers were not affected by any of the variables studied. EOM supplementation and feeding birds on corn increased jejunal villus height at both 21 and 42 days of age, while bird gender showed no effect. In general, EOM positively influenced body weight gain and efficiency of feed conversion in broiler chickens. Birds receiving the corn-based diet were more efficient in converting feed to body mass as com-pared to those fed on the wheat-based diet.

A total of 800 day-old broiler chicks were assigned to four test diets to assess the efficacy of phytase, fermented from Aspergillus niger, and boron, as boric acid, on the growth performance and mineral profile in chickens. The dietary treatments included the basal diet and the basal diet supplemented with boron (20 mg/kg), phytase (500 phytase units/kg diet), or a combination of boron and phytase. The following parameters were measured: growth performance indices, serum biochemicals, ash and the mineral profile of the tibia, breast muscle, liver and excreta. Boron decreased the overall feed conversion ratio by 1.9% (P<0.05) but did not affect the body weight and feed consumption of chickens grown for 42 days (P>0.05). The performance indices were not significantly influenced by dietary regimens for the first 21 days of the experiment (P>0.05). The addition of boron alone and boron + phytase resulted in significant increases in the boron concentrations of serum, bone, breast muscle, liver and excreta (P< 0.001). The serum alanine aminotransferase activity of chicks fed phytase was higher (P<0.05) than all other treatments. The ash content and mineral composition of the breast meat, liver and tibia did not respond to individual or combined dietary modifications (P>0.05). The chickens administered a diet with boron excreted less Cathrough excreta. However, the ash content and Fe and Cu concentrations in the excreta increased in response to phytase supplementation (P<0.05). In summary, supplementation with boron alone improved the feed conversion efficiency of broiler chickens fed diets containing adequate levels of nutrients. However, the combination of boron and phytase did not cause further improvements in broiler performance or the bioavailability of minerals.

Natural zeolite, or sodium aluminosilicate, influences calcium (Ca) and phosphorus (P) utilisation in chicks. A 2×2 factorial arrangement of treatments was used to investigate the effect of dietary Ca (recommended and below recommended levels) and zeolite (0 and 0.8%) on growth, plasma, tibia and faeces in chickens from 1 to 42 days of age. Zeolite supplementation did not affect overall body weight (BW) gain, feed intake (FI) or feed conversion ratio (FCR) of broiler chickens (P>0.05). Overall mortality of zeolite-fed chickens was lower than in untreated ones (P<0.01). Reduction of dietary Ca of approximately 10 to 18% decreased (P<0.05) BW at 14 and 42 days of age in association with reduced FI, but overall FCR was unchanged. Serum protein and sodium constituents were reduced in birds fed zeolite (P<0.05). Decreasing dietary Ca level increased (P<0.01) serum, total protein and glucose concentrations, but decreased Ca level. Zeolite decreased bone ash in birds fed a Ca-deficient diet while increased faecal excretion of ash, Ca, P and aluminum. However, zeolite increased tibia weight (P<0.05) and thickness (P<0.01). No significant response (P>0.05) in relative weight and gross lesion scores of liver or footpad lesion scores was found related to changes in dietary regimens. The results of the present study do not corroborate the hypothesis that the effectiveness of zeolite may be improved in Ca-deficient diets in association with its ion exchange capability.
