Lemongrass Oil

An attempt was taken to study the growth performance of lemongrass oil (Cymbopogon citraturs) as a growth promoter on the broiler production. A total of 180day-old broiler chicks were procured from private hatchery (Shivam Hatchery Birgung, Parsa, Nepal) and were allocated following Completely Randomized Design (CRD) into four treatment groups (each treatment with 3 replications and each replication with 15 birds); T1= control, T2= containing lemongrass oil 200 ml/100 kg feed, T3= containing lemongrass oil 400 ml/100 kg feed and, T4= containing lemongrass oil 600 ml/100 kg feed. The study was carried out for 36 days at Avian Research Unit, Regional Agriculture Research Station, Parwanipur, Bara, Nepal. Concentrate mixture and lemongrass oil were procured from Shakti Feed Industry, Birgung; Herbs Processing Plant of Ministry of Forest and Soil Conservation, Jadibuti, Kathmandu, respectively. Experimental birds were provided ad libitum amount of starter feed from 0 to 21 days and finisher feed from 22 to 36 days. Feed intake was recorded daily and body weight gain was measured in 7 days interval. The study revealed that the cumulative feed intake per bird was found higher in T3 (3443.17g) followed by T4 (3377.33g) and T2 (3354.04g), respectively, and were statistically non-significant among the diet groups. The FCR was highest in T3 (1:1.44 kg) and lowest in T4 (1:1.51 kg), and differed insignificantly among the diet groups. Similarly, the total weight gain of the experimental bird was found to be higher in T3 (2385.13g) followed by T1 (2279.46g) and T2 (2271.86g), respectively.  The average daily gain of experimental birds noted higher in T3 (66.25g) followed by T1 and T2 (63.31g) and (63.1g), respectively. The experiment suggested that inclusion of lemongrass oil could be considered as an alternative to antibiotic growth promoter in broiler diet to enhance the production performance.

Abstract The study was designed to investigate the effect of mannan-oligosaccharide (MOS) supplementation on intestinal histomorphology, immunity against Newcastle disease virus (NDV) and productive parameters of broilers. A total of 1800 day old broiler chicks of Cobb-500 strain were selected and randomly assorted into 6 treatment groups: T1 (basal diet without antibiotics as negative control); T2 (basal diet plus antibiotics as positive control group); T3 (basal diet plus 200g/ton MOS); T4 (basal diet plus 400g/ton MOS); T5 (basal diet plus 600g/ton MOS) and T6 (basal diet plus 800g/ton MOS). Each treatment was having 6 replicates and the feed intake, body weight gain and feed conversion ratio (FCR) were recorded on weekly basis. Results showed that, MOS supplemented birds have significantly higher feed intake, weight gain and FCR (P < 0.05). Similarly, supplementation of MOS showed positive effect on villus height and crypt depth both in jejunum and ilium. Goblet cell density was unaffected by MOS addition (P < 0.05). Furthermore, birds fed with diets containing MOS, exhibited better productive performance in comparison to positive and negative control groups. In conclusion, MOS can replace antibiotic growth promoters (AGPs) as non-microbial performance-enhancing feed advocates.

Abstract Background This study evaluated the effects of supplemental xylanase and xylooligosaccharides (XOS) in a corn-soybean meal (SBM)-based diet on growth performance and intestinal health of broilers. A total of 288 day-old chicks (Cobb 500) were allocated to 36 floor pens (8 birds/pen) equally in 9 dietary treatments in a 3 × 3 factorial arrangement. The treatments were combinations of 3 levels of xylanase (0, 0.005% and 0.01% Econase XT) and 3 levels of prebiotics (0, 0.005% and 0.01% XOS) added to basal mash diets formulated in three phases (starter, d 0–14; grower, d 15–28; finisher, d 29–42). The feed intake and body weights were recorded weekly. On d 42, ileal sections were collected for histomorphometric and gene expression analysis, and cecal content was collected for determining short-chain fatty acids (SCFA) and microbiota. Results Xylanase linearly (P < 0.01) increased the average daily gain (ADG) in both the finisher and total period and the final body weight gain (FBWG, 2940 & 2932 vs. 2760 g) of broilers. XOS did not significantly increase either ADG or FBWG (P > 0.05). Supplemental xylanase and XOS did not affect average daily feed intake and feed conversion ratio (P > 0.05). Xylanase and XOS did not change villus height (VH) or crypt depth (CD) ratio (P > 0.05). However, xylanase exhibited a trend (P = 0.097) on VH:CD ratio. The inclusion of 0.01% XOS without xylanase increased the level of IL-10 (a marker of anti-inflammatory cytokine) and IL-4 (a T-cell differentiation cytokine) genes compared with control (P < 0.05). The acetate production was increased by xylanase (P < 0.01) and XOS (P < 0.05) without an additive effect. Xylanase increased total SCFA (P < 0.01) while XOS had a tendency to increase (P = 0.052). Alpha and beta diversity of microbiota among treatments were not different (P > 0.05). However, the mean proportion of family Ruminococcaceae was increased by the supplemental 0.01% xylanase (P < 0.01). Conclusion It can be concluded that XOS can enhance cecal fermentation, while xylanase can increase the body weight gain along with the fermentation metabolites in the ceca of broilers fed the corn-SBM-based diet but the effects may not always translate into an improved mucosal absorptive capacity and a better feed efficiency.

One hundred and twenty Anak broiler chicks of both sexes were fed furazolidone (additive) in feed to study their growth/weight gain response. The birds were grouped into four, A, B, C, and D of 30 chicks each Treatments B, C and D were administered with furazolidone in feed at the following dosage rates: 0.008%, 0.004% 0.002% respectively. Group A served as control in which furazolidone was not added in the feed. All the groups, (except in feed intake where the control differed significantly) had no significant differences in body weight gain, feed efficiency, and feed intake. It was concluded that it is not necessary to use furazolidone as a growth promoter in broiler feeds.

The efficacy of tulsi (Ocimum sactum) and neem (Azadirachta indica) leaves extract as a growth promoter were studied in broiler. A total of 40 day-old broiler chicks were purchased from Kazi hatchery and after three days of acclimatization the chicks were randomly divided into four groups (n=10). No vaccination schedule was practiced and no antibiotic was added in ration of group A, B, C, and D respectively. Group A served control without any supplements while group B, C and D were supplemented with combination of tulsi and neem extract @ 1 ml, 2ml and 3 ml/liter of drinking water. Live body weight gain was recorded weekly up to 6th weeks and hematological studies were performed at 21st and 42nd day of experiments. At the end of 42nd day of experiment final body weight of group A, B, C and D were 1561± 12.10 g, 1698± 12.87 g, 1608± 12.04 g and 1763± 13.28 g, respectively. The birds of group D utilized their feed more efficiently among the treatment groups (p<0.05). The net body weight gain were, 1533± 11.98 g, 1443± 11.32 g and 1588± 12.10 g in treated groups compared to control group (1393± 11.07 g ) and total net profit per broiler was 19.08, 40.10, 20.68 and 45.07 Taka , respectively. Hematological parameterss (TEC, PCV, Hb and ESR) were not significantly changed among the treated and control group suggesting no side effects of herbal extracts in broiler. It can be concluded that tulsi and neem extract is economic and safe in broiler production.DOI: http://dx.doi.org/10.3329/bjvm.v11i1.17728 Bangl. J. Vet. Med. (2013). 11 (1): 1- 5

This study was carried out to evaluate the feeding effect of high yielding fodders (HYF) on feed intake and growth performance of growing Hilly Brown Bengal (HBB) goat. For this purpose, a feeding trail was conducted with 16 growing HBB kids (4 to 5 months) by dividing equally in four groups having four replicates for a period of 75 days. The goats in group T0 (control) received natural grass along with 101.30g concentrates and adlibitum cowpea hay, whereas in group T1, T2 and T3, only natural grass was replaced by BLRI Napier 3, BLRI Napier 4 and Ruzi fodder, respectively. Total dry matter intake (DMI), roughages DMI, crude protein intake (CP), body weight gain (kg), average daily gain (g) and forth night body weight gain (g/day) were studied. Results revealed that, DMI (288.39, 285.71, 293.48 and 301.35 g/day in group T0, T1, T2 and T3, respectively), body weight gain (3.60, 3.74, 3.73 and 3.77 kg in group T0, T1, T2 and T3, respectively), average daily gain (47.32, 49.16, 49.12 and 48.92 g in group T0, T1, T2 and T3, respectively) and feed conversion ratio (6.2, 5.9, 6.0 and 6.1 in group T0, T1, T2 and T3, respectively) of HBB kids were not differed significantly (P>0.05) for all the treatment groups. The DMI from roughages (196.2, 193.5, 201.3 and 209.2 g/day in group T0, T1, T2 and T3, respectively) and CP intake (38.7, 42.1, 48.3 and 38.8 g/day in group T0, T1, T2 and T3, respectively) were significantly varied (P<0.05), while highest CP intake was found in the treatment group T2. Forthnight body weight (g/day) was not significantly (P>0.05) gained with feeding of HYF for all the treatment groups. From this study, it can be concluded that, growing HBB kids could equally be supplied with either BLRI Napier 3 or BLRI Napier 4 or Ruzi fodder in addition to ad libitum cowpea hay for better voluntary feed intake and growth.

In the present feeding trial, responses of laying hens, kept at high ambient temperature, to various dietary ratios of linoleic acid (LNA) to α-linolenic acid (ALA) and vitamin A levels on performance and egg characteristics were evaluated. A total of 360, 40-wk-old, Leghorn laying hens were fed on diets with various combinations of canola oil and linseed oil to achieve LNA to ALA dietary ratios of 20:1, 10:1, 4:1, 2:1, 1:1 and 1:2, each supplemented with 3000 IU or 10000 IU vitamin A/kg of diet. The diets were fed in a 6×2 factorial Completely Randomized Design that continued for 12 weeks. Feed intake, weight gain, egg production and egg quality traits were recorded during the trial. Decreasing dietary LNA to ALA ratio in the diet affected negatively (P<0.05) on body weight gain and yolk percentage in laying hens. While, feed intake, hen-day and hen-housed egg production, feed conversion ratio (FCR) per dozen of eggs and shell quality remained unaffected (P>0.05) by dietary treatments, with the exception of FCR per kg eggs, egg weight and egg-shell thickness which responded significantly (P<0.05) to various dietary treatments. Although the dietary ratio of LNA to ALA of 4:1 or less could produce eggs by the hens with desirable quantities of n-6 and n-3 poly unsaturated fatty acids – that are characteristics of functional diets – the performance of laying hens in terms of body weight gain and egg-yolk percentage was slightly compromised.

Considering the inherent attributes of tannia cocoyam (Xanthosoma sagitifolium) its appropriate utilization may enhance performance of starter broiler chicks. This study was therefore carried out to determine the dietary evaluation of starter broiler chicks fed cooked cocoyam tuber meal as energy source in place of maize. The cooked cocoyam tuber meal was used to replace maize at various levels of 25%, 50%, 75% and 100% respectively for diets 2, 3, 4 and 5 to determine the best replacement level that would give optimal performance in starter broiler chicks' diets. Result of the proximate composition of cooked cocoyam tuber meal showed that it contained 13.11% moisture, 2.60% ash, 1.85% ether extract, 3.90% crude protein, 9.45% crude fibre, 70.13% nitrogen free extract and 3004.37 Kcal/kgME. 150 day old Anak broiler chicks were used for the experiment. They were divided into 5 treatment groups of 30 broiler chicks each. Each treatment group was subdivided into 3 replicates of 10 broiler chicks each and kept in deep litter. Each starter diet was fed to a group of 30 starter broilers for 4 weeks using completely randomized design. They were given feed and water adlibitum. Parameters measured include initial body weight, final body weight, body weight gain, feed intake, feed conversion ratio and economics of production. In the starter broiler feeding trial, the starter broilers on 25% cooked cocoyam meal compared favourably with the control (P> 0.05) in terms of feed intake, body weight gain and feed conversion ratio and significantly (P > 0.05) performed between than those on 100% CCYM. The cost of production (N/Kg broiler) was however cheapest for diet 2 (25% CCYM) N395 versus control diet (N494.28). It was therefore concluded that cooked cocoyam tuber meal (Xanthosoma sagitifolium) could be used in the diets of starter broiler chicks' up to 25% without affecting the body weight gain, feed intake and feed conversion ratio as indicated in this study.

The effects of feeding probiotic (PB) with or without Lincomycin 2.2% (AGP) were investigated in broiler chickens during summer. Seven hundred Cobb-500 one day old straight run broiler chicks were randomly distributed into four dietary treatments each of five replications. Four diets were compared: control; control diet plus PB (Bacillus subtilis DSM17299) at a level of 50g/100kg; control plus (AGP) at a level of 15g/100kg and control plus a combination of PB and AGP (50gm/100kg and 15g/100kg respectively). Control birds were fed on a corn-soybean based starter mash that contained ME 3000 kcal/kg and CP 24.39% from 0-21 days of age and a corn-soybean based grower mash of ME 3100 kcal/kg and CP 20.43% during 22-35 days of age. The records were kept of feed intake (FI), body weight and mortality while weight gain, feed conversion ratio (FCR) and survivability were calculated. Temperature and humidity were recorded four times daily except during extreme heat stress when measurements were made more frequently. One bird that was close to average of pen weight was taken from each replication at the end of the trial and the birds were sacrificed to determine carcass characteristics. Both performance and carcass yield data were statistically analyzed. Birds that received PB and a combination of PB +AGP treatments showed significant differences (P<0.01) from control with respect to body weight gain and FCR while feeding AGP alone although showed a decrease in feed intake. Abdominal fat was significantly (P<0.01) reduced in PB treated birds. Higher mortality was encountered in control group. Both PB alone and a combination of AGP treatments were able to show improved performance and reduced mortality, feeding PB alone may be practiced on the combined grounds of improved performance, efficiency in combating heat stress and to discourage the use of AGP in broiler diet.Asian J.

An extract of nishyinda (Vitex negundo) leaves, black pepper (Piper nigrum) and cinnamon (Cinnamomum verum) (polyherbal extract) were used as growth promoter in broilers. A total of 20 day-old broiler chicks were purchased and after seven days of acclimatization randomly divided into two equal groups. No vaccination schedule was practised and no antibiotics were added in rations. Group A served as control while group B was supplemented with polyherbal extract 1 mL/litre in drinking water. Weekly body weight gain up to six weeks was measured and blood tests were performed at 21 and 42 days. Polyherbal extract significantly (P<0.05) improved weight gain. There was no change in haematological parameters. It can be concluded that the polyherbal extract was safe as a growth promoter in broiler production without adverse effects on chicken health.

This study was conducted to determine the efficacy of tulsi (Ocimum sanctum) leaves extract as a growth promoter in broilers from January to June 2013 under Dept. of Pharmacology, Bangladesh agricultural University, Mymensingh-2022, Bangladesh. Fourty number of day old broiler chicks were taken and after seven days divided into two groups A and B. The B group was supplemented with tulsi leaves extract @ 1ml/litre in drinking water. Weekly observations were recorded for live body weight gain up to 5th weeks and blood test was performed at 17th and 35th days age of broiler to study hematological changes between control A and treatment B group. No significant difference in hematological changes was observed in both treatment and control group in 1st week of age but significant change in body weight gain was observed on 35th day. They are 1500 g (control) and 1650 g (treated). The cost of production and economic study was carried out and it was observed that net profit in control group was 5.33 T.K/Kg broiler and in treatment group was 13.33 T.K/Kg broiler. Bacterial sensitivity test was positive in case of Escherichia coli and produced zone of inhibition 0.5 cm and other was negative.Asian J. Med. Biol. Res. June 2017, 3(2): 226-232
