Chicken meat tends to be high in polyunsaturated fatty acids and cholesterol, which may increase the risk of atherosclerosis, stroke and other associated diseases. A study was conducted for 42 days to evaluate the efficacy of dietary supplementation of two phytogenic feed supplements viz. AV/LMP/10 and AV/HLP/16 (M/s Ayurvet Limited, India) for their ability to produce lean meat in commercial broiler chicken. One hundred and fifty (150) one-day old Cobb-400 broiler chicks were randomly allocated to five equal groups. All the groups were fed standard basal ration. T0 was control group (without treatment), groups T1 and T2 were supplemented with AV/LMP/10 @ 500 g/ton and 1 kg/ton of feed, respectively. Groups T3 and T4 were supplemented with AV/HLP/16 @ 1 kg/ton and 1.5 kg/ton of feed, respectively. On day 42, significantly better (P<0.05) results were obtained in the treated groups (T1-T4) in terms of body weight (2118.10±0.61, 2159.20±0.34, 2098.90±0.41, and 2180.40±0.56 g), total protein (19.10±0.56, 19.93±1.18, 20.80±0.36, and 21.04±0.64%), crude fat (1.25 ±0.25, 1.25 ± 0.31, 0.92 ± 0.24, and 1.03 ± 0.03%), pH (6.01 ± 0.07, 5.93 ± 0.09, 5.78 ± 0.08, and 6.06 ± 0.09), TBARS value (1.11±0.07, 1.11±0.05, 1.06±0.06, and 1.08±0.06 mg/Kg), cholesterol (54.19±1.11, 35.72±1.71, 45.61±1.54, and 36.09±1.045 mg/dL), HDL cholesterol (16.70±0.56, 12.61±1.28, 14.16±1.02, and 15.59±0.57 mg/dL) and total lipids (1.60±0.13, 1.56±0.22, 1.64±0.15, and 2.03±0.12 mg/g) in comparison to the untreated group (2050.80±0.71 g, 18.15±0.41%, 1.66 ± 0.48%, 6.07 ± 0.08, 1.18±0.09 mg/Kg, 62.36±0.88 mg/dL, 24.25±0.54 mg/dL and 2.42±0.18 mg/g). FCR and slaughter parameters varied non-significantly among different groups. The meat: bone ratio was numerically higher in the treated groups T1-4 (2.01±0.20, 2.09 ±0.19, 2.16±0.20 and 1.89±0.35) as compared to the control group (1.80±0.18). The highest protein content was obtained in T4 (21.04%) followed by T3 (20.80%), T2 (19.93%), T1 (19.10%) and lowest in T0 (18.15%), while highest crude fat was obtained in the muscles of the control group T0 (1.66%) followed by T1 and T2 (1.25%), T4 (1.03%) and T3 (0.92). Overall sensory acceptability of meat also improved in the supplemented groups. From the present study, it could be concluded that the phytogenic formulations AV/LMP/10 and AV/HLP/16 were effective in lean meat production in broiler chicken.

This study was conducted to observe the effect of different administration method of garlic and neem on growth performances, feed efficiency and serum biochemical parameters for safe broiler production. The experiment was done for a period of 32 days with 384 one-day-old straight run broiler chicks. The broiler chicks were divided into six groups each of 64 birds and replicated to four subgroups each of 16 birds. The dietary groups were; control (basal diet; no additives), antibiotic (basal diet + antibiotic), garlic in feed (basal diet + 0.25% garlic powder), garlic in water (basal diet + garlic extracts), neem in feed (basal diet + 0.25% neem powder) and neem in water (basal diet + neem extracts). Results showed that the body weight and body weight gain increased significantly (P<0.05) in both the garlic and neem groups compared to the control group. Feed intake was not different (P>0.05) among the treatment groups. Garlic in feed and water and neem in feed groups showed better FCR (P<0.05) compared to the other treatment groups. There were no significant (P>0.05) difference in meat yield, bone development and dressing parameters except head and gizzard in different dietary groups. Supplementation of garlic with feed and water significantly (P<0.05) decrease cholesterol, triglyceride and LDL compared to the other groups. However, both the garlic and neem groups showed numerically higher HDL compare to the control group. There were no 0significant (P>0.05) differences in serum glucose and GPT among different treatment groups. GOT was significantly (P<0.05) lower in neem groups than that of garlic and antibiotic groups. Additive groups showed higher profitability than control group. Based on the results of the study, it may be suggested that the garlic and neem could be used both in feed and water as potential feed additives for safe broiler production. Bang. J. Anim.

Abstract The broiler chicks provide the major portion of daily food items. The current study aimed to investigate the effects of Bacillus subtilis (BS) on broiler chicken gut microflora diversity, digestive enzyme activity and expression of Toll-like receptors (TLRs). A total of 240 crossbred broiler chickens were randomly allocated into 4 groups with 3 replicates. The groups were named as control group (basal diet, BD), group Ⅰ (BD with 300 g/d BS,1.08×107 CFU/kg), group Ⅱ (BD with 600 g/d BS, 2.16×107 CFU/kg), and group Ⅲ (BD with 900 g/d BS, 3.24×107 CFU/kg). Samples were collected at the 21st day. The difference of α diversity and β diversity between control group and treatment groups were not significant, but the abundance of some microorganisms in the treatment groups were improved, and the core microorganisms were different between groups. In comparison of control group, the protease activity in ileum of experimental groups was significantly increased (p < 0.05). Protease activity in ileum of group Ⅱ and Ⅲ was improved by 22.59% (p < 0.01) and 14.49% (p < 0.05). The amylase activity in ileum of treatment groups were also significantly increased (p < 0.05). Amylase activity of group Ⅱ was increased by 41.85% (p < 0.01) in comparison to control, group Ⅰ and Ⅲ. Expression of TLR1A and TLR7 in the jejunum and caecum of treatment groups were significantly up-regulated while their expression in ileum was decreased. Similarly, the expression of TLR1B gene was significantly improved in the ileum, and down regulated in the cecum. Transcription levels of TLR2A and MyD88 in jejunum, liver, spleen and kidney were significantly increased, but their expression was significantly lower in the ileum and cecum. The TLR2B, TLR3, TLR4, TLR15, TLR21 expression were also significantly modulated in various organ of broiler chicken. The most important inflammatory factor such as IL-1β expressions in spleen and kidney were significantly increased in the current data. Bacillus subtilis could not regulate the caecal microflora diversity, but improved amount of some gut probiotics such as lactobacillus, the digestive enzyme activity, regulate some immunogenic expressions and enhance the immune capacity of animal. We hope that the impact of this data will explore the diseases control and feeding quality of broiler chicks at industrial level.

The present study was undertaken to evaluate the efficacy of aspirin as anti-heat stressor. Broiler chicks were reared on a standard diet up to 14 days of age. Thereafter, the chicks were randomly distributed into three dietary treatment groups viz., T1 (Control group: Standard diet), T2 (Standard diet with aspirin@250 mg/kg) and T3 (Standard diet with aspirin@500 mg/kg). Each treatment was having five replicates of eight birds per replicate. Experiment was carried out during hot-dry (April-May, 30.0±0.70 to 37.0±1.40C, Rh, %: 58.05±1.32 to 70.11±0.82) summer. Feed intake and live weight gain was comparable among the treatments but FCR, protein and energy efficiency improved significantly (P less than 0.001) on aspirin supplementation. The relative yield of thymus and bursa at 4th and 6th week of age improved significantly (P less than 0.05). The percentage of protein, aspartate transaminase (AST) and alanine transaminase (ALT) increased significantly (P less than 0.001) due to aspirin supplementation at 4th as well as 6th week of age. While H:L ratio, serum corticosteron and serum cholesterol (only at 42nd day of age) decreased significantly (P less than 0.001) in aspirin supplemented groups at 28th as well as 42nd day of age. Supplementation of aspirin at 500 mg/kg reduced relative expression of HSP70 in jejunum tissues during 28th or 42nd day of age. It can be concluded that aspirin supplementation 500 mg/kg in diet of heat stressed broilers improved performance as well as welfare..

The study was conducted to access the effect of early post-hatch nutrition regimens on the productive performance of 384 number of commercial broiler chicken (Cobb 400). Different nutrient regimens include glucose and probiotic alone in hatcher tray and first day in pen and a high and very high density diet of 25 and 27 per cent dietary crude protein respectively and 3100 kcal ME/kg diet in hatcher tray and subsequent three days in pen along with glucose and probiotic alone in hatcher tray and first day in pen was provided. Later, all broiler chicks were switched over to the recommended commercial Cobb broiler diet up to 42 days. Body weight, feed efficiency and breast muscle fibre diameter were significantly higher in treatment groups. No significant difference existed between different treatment groups for hatchability, livability percent, carcass characteristics and cut up parts. Trimmable fat per cent was significantly higher (P less than 0.01) in control birds. It may be concluded that early post hatch nutrition with high nutrient dense diet resulted in better production performance in commercial broiler chicken.

An experiment was conducted to investigate the effect of supplementing of exogenous phytase enzyme on productivity of commercial broilers. Four strains of commercial broiler such as Fast feather, Arbor acres, Cobb-500 and Hubbard classic each having 78 numbers were reared for a period of 5 weeks. A total number of 312 day old broiler chicks were distributed into two dietary treatments i.e. basal diet (Control-T0) and basal diet supplemented with phytase enzyme 1g/kg feed (supplemented-T1). The results indicated that broilers fed on diets supplemented with phytase have gained more body weight when compared with control group (P<0.05). The first and second highest body weights were recorded for the strains Cobb-500 and First feather broilers, respectively, which feed on diet containing phytase.   Feed consumption varied significantly between the broilers on different dietary regimes. Significant differences (P<0.01) were found in feed conversion ratios among the birds fed on diet with phytase enzyme. The lowest feed conversion ratio was in Cobb-500 fed on phytase diet where as the highest was in Fast Feather provided with only basal diet during the 5th week of age. Average feed conversion ratios were 1.73 and 1.86 for the supplemented and control group respectively. Use of phytase as feed additive in the diet resulted in high profitability/ broiler. Net profit per live broiler was the also higher in treatment group compared with control groups of birds. The highest net profit per live broiler was observed in Arbor Across strains fed on phytase diet. The result of the present study suggests that the addition of dietary phytase enzyme in the diet of broiler may increase the production performance and reduce the cost of production.Bang. J. Anim.

SUMMARYThe carcass characteristics of young adult female pigs (gilts) slaughtered after weaning their first litters have been investigated using three groups of 19 Landrace × (Landrace×Large White) gilts. In two treatment groups gilts were mated at their pubertal oestrus and suckled their piglets for 5 to 11 and 35 to 42 days respectively. These gilts were slaughtered on average 10 days after weaning. A third control group consisted of unmated gilts slaughtered at 118 kg live weight.There was no significant difference in the killing-out percentage for the three groups. The carcasses of the gilts which farrowed contained significantly less fat (P<0·001) than those of the unmated controls. The carcasses of the farrowed gilts had significantly lighter middle sections (P<0·001) and significantly heavier shoulders (P<0·001) than the controls.Despite the variations in tissue yield and distribution, the yield of prime joints for the gilts which had farrowed was only 0·62 percentage units less than that of the controls.No commercially significant variations between groups in meat quality were observed.

To investigate the effect of dried Bacillus subtilis culture on growth, body composition and hepatic lipogenic enzyme activity, female broiler chicks were fed on either no additive (control) or dried B. subtills-culture-supplemented commercial diets (215 g crude protein/kg, 12.85 MJ metabolizable energy/kg) at 10 or 20 g/kg diet for 28 d from 14 to 42 d of age. Body weight, and moisture, fat, protein and ash contents of the body were not influenced by the B. subtilis culture. Feed efficiency. N utilization, the ratio of abdominal fat or liver to body weight, acetyl-coenzyme A carboxylase (EC 6·4·1·2) activity, liver and serum cholesterol contents were significantly lower in treatment groups, while fatty acid synthetase activity and serum cholesterol concentration were not significantly different, compared with the control group. Liver triacylglycerol concentration was decreased in chicks given 20 g culture·kg diet, while serum and carcass triacylglycerol concentrations were significantly lower in treatment groups than in the control group. Serum phospholipid concentration was increased but carcass phospholipid concentration was decreased in chicks given 20 g B. subtilis/kg diet, while liver phospholipid concentration was not significantly influenced. The advantages of inclusion of B. subtilis to the broiler diet included improved feed efficiency, less abdominal fat, reduced triacylglycerol concentrations in the liver, serum and carcass and reduced cholesterol concentrations in the liver and carcass.
