This study assessed the effect of the combination of microencapsulated sodium butyrate (SB) and phytase (PH) on the performance, intestinal integrity, and bone development of broilers. The experiment comprised 736 chicks distributed in a completely randomised design in a 2 × 2 factorial scheme (with and without the inclusion of SB and with the inclusion of PH at the recommended dose and superdosing) totalling four treatments and eight repetitions of 23 birds each. SB was added at 0.750 kg/tonne and PH was included at 750 phytase units (FTU)/kg and 1 500 FTU/kg of diet. The live weight (LW), feed intake (FI) and feed conversion (FC) were evaluated weekly. Bone measurements of the tibia and femur, densitometry, length, the Seedor index, and diameter were performed at seven and 28 days. In the same ages, fragments of the jejunum and ileum segments were collected and subjected to a morphometry analysis. At seven days of age, the birds supplemented with the phytase superdosing showed a better FI and LW, and the microencapsulated SB in the diet showed a better LW and FC. In the period from one to 28 days, the treatment supplemented with SB provided a higher FI and LW. The SB supplementation resulted in greater bone measurements at seven and 28 days. The use of the superdosing phytase increased the villus length and width of the jejunum at seven days and at 28 days. There was an increase in the villus length, villus-to-crypt ratio, absorption area, and muscular layer of the jejunum and a decrease in the crypt width of the jejunum. The SB supplementation increased the ileum crypt width at seven days and there was no effect on any intestinal segment at 28 days. The supplementation of SB or PH 1 500 FTU/kg in the broiler diets’ growth promoter or antibiotic-free resulted in a better performance and bone measurements, while the association of the additional PH 1 500 FTU/kg and SB supplementation resulted in the greater depth and width of the jejunum crypt and villus : ileum crypt at seven days and greater villus length and ileum absorption area at 28 days. The association of SB and PH may be a strategy to improve the performance and bone quality and intestinal integrity in broilers.

The objective of this work was to evaluate the effects of two types of incubation and two types of feeding on the performance of chickens and intestinal development of chicks during the pre-starter phase (1 to 7 days of age). One-year-old male Ross® chicks were used. The experimental design was a randomized complete block design, in a 2x2 factorial design, with two types of feed processing (bran and micropelleted) and two types of incubation machines (single and multiple stage), totaling four treatments, with four treatment repetitions each. Twelve birds per experimental unit were used, totaling 192 animals. Performance evaluations were conducted, such as mean weight, weight gain, feed intake, feed conversion, bowel weight and size, and percentage of intestine in relation to live weight. Histomorphometric tests on the height of the villi and depth of the duodenal crypts were also performed. The two incubation machines did not influence any of the analyzed variables. Even though both had the same composition, the micropelleted feed resulted in positive gains for the performance variables: average weight, weight gain, feed intake, and feed conversion when compared to the meal, but was unable to significantly influence the morphometric measurements of the duodenum of chicks in the pre-starter phase.

This study aimed to assess the effect of stocking density of 10, 12, 14, and 16 birds m?2 on performance, carcass and cut yields, productivity, and bone development of broiler chickens Cobb 500®. The experimental design was completely randomized design with four treatments (stocking densities) and four replications. The assessments were performed weekly at 1, 7, 14, 21, 28, 35, and 42 days. The best live weight result was found at a density of 10 birds m?2 in the period from 1 to 7 days. No effect of density was observed on feed intake and weight gain. From 1 to 14 days, the best live weights were found at densities of 10, 12, and 14 birds m?2, in addition to a higher feed intake at densities of 10 and 12 birds m?2. Weight gain was better at a density of 10 birds m?2, showing no differences from densities of 12 and 14 birds m?2. In the period from 1 to 21 days, live weight and weight gain were higher at densities of 10, 12, and 14 birds m?2. The highest feed intake was observed at a density of 10 birds m?2, which showed no difference from the density of 14 birds m?2. A difference (P < 0.05) was observed for live weight, weight gain, and feed intake of animals reared at densities of 10, 12, and 14 birds m?2 for the phases from 1 to 35 days and the total phase from 1 to 42 days of bird age when compared to 16 birds m?2, which presented lower performance. However, feed conversion of 1-7, 1-14, 1-21, 1-35, and 1-42 days and carcass and cut characteristics showed no significant differences for all treatments. On the other hand, productivity was higher in the treatments with 14 and 16 birds m?2, but without difference between each other. No interaction (P > 0.05) was observed between stocking density and age for the assessed bone parameters. Similarly, no difference (P > 0.05) was observed for bone development of broiler chickens reared at different stocking densities for the studied parameters. Thus, the increased density of 10 or 12 birds m?2 to 14 birds m?2 has no influence on zootechnical performance, carcass and cut yields, and bone development, but increases broiler chicken productivity reared in a conventional shed without air conditioning.

The purpose of this study was to determine the effect of adding coated sodium butyrate at various levels to the rations of laying hens on their performance, egg quality, and some blood parameters. In this study, a total of 72 laying hens at the age of 60 weeks were fed for 56 days with the control ration and the rations containing sodium butyrate at various levels (300, 600, and 1200 mg/kg). The study was carried out in 4 treatment groups, each with 6 replicates. As a result of the study, there was no statistically significant difference between the treatment groups in terms of live weight change, egg yield, feed consumption, feed conversion ratio, egg weight, and egg mass. The addition of sodium butyrate to the rations of laying hens did not have a statistically significant effect on the egg shell breaking strength, eggshell ratio, shell thickness, egg shape index, albumen-yolk index, damaged egg ratio, and egg yolk colour criteria (L*, a*, and b*). Whereas there was no statistically significant difference between the treatment groups in terms of the levels of cholesterol, HDL, albumin, Ca, and P; some statistically significant differences were observed in terms of the levels of serum globulin, total protein, and uric acid. Based on the findings of the study, it was concluded that there was no need to add sodium butyrate to the ration for improving the performance and egg quality in the laying hens at the age of 60 weeks.

An eight week feeding trial was carried out to compare the effect of antibiotic growth promoter (streptomycin) (AGP) and formic acid (FA) on growth and nutrient digestibility in broiler. A number of 150 day old (Hubbard strain) birds were allocated in 05 dietary groups viz. control, control with 0.02% AGP, control with 0.25% FA, control with 0.50% FA, control with 0.75% FA. Each group was replicated thrice having 10 birds and the birds were fed diet and water ad libitum for 8 weeks. Apparent digestibility of nutrients was determined at the end of the experiment. A significantly (p<0.05) reduced feed intake, improved feed: gain ratio and protein utilization were obtained for starter broilers fed 0.02% AGP, 0.5% FA and 0.75% FA. During finisher phase, AGP and 0.5% FA performed better in live weight, feed conversion ratio and protein utilization. Streptomycin and all the levels of FA resulted to better protein and ether extract digestibility. It may be suggested to use 0.50% FA in the diet of broilers in place of antibiotics.DOI: http://dx.doi.org/10.3329/bjas.v44i1.23146              Bang. J. Anim. Sci. 2014. 44 (1): 69-74

ABSTRACT: The aim of this study was to evaluate two feed additives, one based on encapsulated sodium butyrate (Adimix® Precision) (AD) and the other, a phytogenic (Apex® 5) (AX), associated or not with an antimicrobial growth promoter (tylosin) during the growth and finishing phases on performance, carcass characteristics and health conditions. A total of 300 barrows and females were distributed in six treatments in a randomized block design with ten replicates. The treatments consisted of a negative control (NC), positive control (PC) (tylosin), AD (encapsulated sodium butyrate), AX (phytogenic), PC+AD (tylosin+encapsulated sodium butyrate), and PC+AX (tylosin+phytogenic). The performance (live weight, daily feed intake, average daily gain and feed conversion) and carcass data (carcass weight, backfat thickness, loin depth, lean meat on the carcass) were submitted to ANOVA plus Tukey’s test, and the health conditions (occurrence of diseases, culling, and spontaneous deaths) were analyzed by χ2. Animals of the AD group had the highest average daily gain (ADG) over the evaluation period and the highest live weight at 120, 140, and 164 days of age, in addition to the highest carcass weight compared to NC and PC groups. The AX treatment increased the ADG in growth phase II and the live weight at 120 and 140 days of age in relation to the NC. The PC+AX group had a higher final live weight compared to the NC and PC groups and higher carcass weight in relation to the NC group. There was no difference among treatments for backfat thickness, percentage of lean meat in the carcass, or occurrence of diseases and deaths. The inclusion of encapsulated sodium butyrate (AD treatment) was effective in increasing ADG, final live weight, and carcass weight compared to supplementation with tylosin (PC treatment), as was the inclusion of a phytogenic (AX treatment) on FC compared to the PC.

Bull Calves

The aim of the study was to evaluate and compare the effect of growth promoter 'Megavit-DB' on growth performance of indigenous Red Chittagong (RC) and Holstein Crossbred (HC) bull calves. For this purpose, six RC and six HC bull calves were assigned into four treatment groups having three calves in each as RCT0 (RC without Megavit-DB), RCT1 (RC with Megavit-DB), HCT0 (HC without Megavit-DB) and HCT1 (HC with Megavit-DB). The daily DM intake of different treatment groups were found almost similar. The daily average live weight gains were 0.27±0.05, 0.36±0.01, 0.36±0.01 and 0.45±0.05 kg/d, feed conversion efficiency were 9.08±0.16, 7.47±1.07, 7.13±1.24 and 6.16±0.27 and the average net returns (Tk.) were 1473.33±87, 2060±76.38, 1910±86.60 and 2776.67±44.10 for RCT0, RCT1, HCT0 and HCT1 treatment groups, respectively. The daily average live weight gain and feed conversion efficiency were significantly (p<0.05) higher in HCT1 than that from RCT1, HCT0 and RCT0. Accordingly, the average net returns were found significantly (p<0.05) higher in HCT1 than RCT1, HCT0 and RCT0. It may be concluded that Megavit-DB may have the potentials to improve growth performance of both HC and RC and may be used in cattle fattening program.

Coriander Seed

A total of 72 as hatched Cobb 500 broilers were fed ad libitum on a diet with 0 %, 0.5 %, 1.0 % and 1.5 % of coriander seed meal (CSM) to assess its feeding value. Treatment group with 1.5 % of CSM significantly (p<0.05) affected live weight of broilers at the age of 28 and 35 days. Among the dietary groups there is no significant difference in feed intake and feed efficiency. Meat yield characteristics especially abdominal fat level decreased significantly (p<0.01) at 1.5 % level of CSM. Cost of production per kg live broiler decreased when dietary inclusion level was increased. Profit per kg of live broiler was significantly (p<0.05) increased with the increase levels of dietary CSM. These results suggest that the CSM could be considered as a potential natural growth promoter for poultry, and showed the best responses at a 1.5 % level of inclusion. It was concluded that the supplementation of the coriander seed meal to broiler diet had beneficial effects on body weight gain, feed conversion ratio and carcass yield.DOI: http://dx.doi.org/10.3329/bjas.v43i1.19383 Bang.

Feeding cupric citrate as alternative to cupric sulfate to broilers has been suggested in the literature. Day-old male broiler chicks (1,200) were used in an experiment to evaluate the efficacy of cupric citrate supplementation (75 mg Cu kg-1) during the 1-21, 22-42 or 1-42 d periods in comparison to an unsupplemented diet and a diet supplemented with cupric sulfate (200 mg Cu kg-1, 1-42 d). A randomized block design was used, with five treatments, six replicates and 40 birds per pen. The diets, based on corn and soybean meal, and water were offered ad libitum during the 42-day experimental period. Over the entire period, there was no effect of copper supplementation (P > 0.05) on bird live weight, weight gain, feed intake, feed conversion and mortality. Cupric citrate supplementation on the 22-42 d period resulted in worse feed conversion as compared to broilers receiving cupric sulfate (2.014 vs. 1.967, P < 0.05). Copper residues in the litter were reduced when broilers were fed cupric citrate, as compared to cupric sulfate (P < 0.01). The absence of response to copper supplementation can be attributed to the environmental and sanitary rearing conditions.

Abstract The study aimed to evaluate a commercial blend of functional oils based on liquid from the cashew nutshell and castor oil as a growth promoter in newly weaned piglets. A total of 225 piglets, castrated males and females with 28 days of age were randomly distributed in pens with 15 animals composing three treatments and five repetitions. The treatments were: control (without the inclusion of additive), probiotics, or functional oils. The performance was evaluated. At 50 days of age, a pool of fresh feces from 3 animals/repetition was collected to perform the sequencing of microbiota using the Illumina MiSeq platform. Supplementation with functional oils improved the piglets' daily weight gain and feed conversion ratio (P < 0.05) in the first weeks of the experiment, which resulted in higher final live weight (P < 0.05) in the phase when compared to the control treatment. The animals that received probiotics showed intermediate performance. Both additives were effective in modulating groups central to intestinal health, such as Ruminococcaceae and Lachnospiraceae. The functional oils were more effective in reducing pathogenic bacteria, such as Campylobacter and Escherichia coli. In conclusion, the use of functional oils optimized performance and effectively modulated the microbiota of newly weaned piglets.

AbstractThe study aimed to evaluate a commercial blend of functional oils based on liquid from the cashew nutshell and castor oil as a growth promoter in newly weaned piglets. A total of 225 piglets, castrated males and females with 28 days of age were randomly distributed in pens with 15 animals composing three treatments and five repetitions. The treatments were: control (without the inclusion of additives), probiotics, or functional oils. The performance was evaluated. At 50 days of age, a pool of fresh feces from 3 animals/repetition was collected to perform the sequencing of microbiota using the Illumina MiSeq platform. Supplementation with functional oils improved the piglets' daily weight gain and feed conversion ratio (P < 0.05) in the first weeks of the experiment, which resulted in higher final live weight (P < 0.05) in the phase when compared to the control treatment (24.34 kg and 21.55 kg, respectively). The animals that received probiotics showed an intermediate performance (23.66 kg final live weight) at the end of the 38 experimental days. Both additives were effective in increasing groups essential for intestinal health, such as Ruminococcaceae and Lachnospiraceae. The functional oils were more effective in reducing pathogenic bacteria, such as Campylobacter and Escherichia coli. In conclusion, the use of functional oils optimized performance and effectively modulated the microbiota of newly weaned piglets.
