This study was aimed at determining the effective ingredients of yeast culture (YC) for animal breeding. First, the contents of YCs obtained from various fermentation times were detected using gas-chromatography. A total of 85 compounds were identified. Next, 336 Arbor Acres (AA) broilers were randomly divided into seven experimental groups and fed a basal diet, diets supplemented with YCs obtained at various fermentation times, or SZ1 (a commercial YC product). A significant increase in body weight gain (BWG) and a significant decrease in feed conversion ratio (FCR) of AA broiler chicks were observed with YC supplementation. Additionally, most of blood and immunological indices were improved with YC supplementation. According to the production performance and the results of multivariate analysis, glycine, fructose, inositol, galactose, and sucrose were found as the potential effective compounds of YC and were involved in metabolic pathways including glycine, serine, and threonine metabolism. Supplementation with diets based on combinations of effective compounds improved weight gain, feed efficiency, serum immunoglobulin A, and immunoglobulin G, but decreased blood urea concentration. These findings suggest YCs as effective and harmless feed additives with improved nutritional properties for broiler chicks.

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.

An experiment was conducted with 312 day-old male broiler chicks in grower phase(8-28d) to estimate the biological availability of four sources Zinc (Zn), Zinc sulfate(ZnSO4.H2O), two sources of Zinc oxide(ZnO FG1 and ZnO FG2) and Bioplex Zn. Zinc sulfate (ZnSO4.H2O) was used as the standard in the bioavailability assay. Chicks were allotted randomly to 13 dietary treatments with 6 birds per replicate and 4 replicates per treatment, that included an unsupplemented corn-soybean meal basal diet (25.50 mg of Zn/kg of DM), or the basal diet supplemented with 100, 150 or 200 mg/kg of DM as either ZnSO4.H2O (33 % Zn), Zinc oxide FG1(72%Zn), Zinc oxide FG2 (75%Zn) or Bioplex Zn (15% Zn). Dietary Zn level and source had no effect (P>0.05) of feed intake or body weight gain of chicks during first and second weeks of experimental periods, but feed conversion ratio in the first and second week and feed intake, body weight gain or feed conversion ratio in third week and total experimental periods were significant difference between treatments (P<0.05). The relative biological availability values using body weight gain were estimated to be 59, 99 or 45 for three levels of Zinc oxide FG1, 64, 78 or 31 for three levels of Zinc oxide FG2 and 151, 200 or 147 for three levels of Bioplex Zn, respectively. From the standpoint of bioavailability, Bioplex Zn was more available to broiler chicks than Zn from other sources and can be used by the feed industry as sources of supplemental Zn for broiler chickens.

A feeding trial of 42 days was conducted to discern the effect of dietary incorporation of giloe and cinnamon powder on growth performance in commercial broilers .One hundred and twenty, day old Vencobb broiler chicks were procured and divided randomly into 6 treatment groups with 2 replicates of 10 chicks each viz., T1 (control) were fed basal diet whereas in treatment group T2, T3, T4, T5 and T6, basal diet was incorporated with 1% giloe, 2% giloe, 1% cinnamon, 2% cinnamon and combination of 1% giloe and 1% cinnamon, respectively. During starter phase (0-21 days), the body weight gain was significantly (P£0.05) higher in T3incorporated with 2% giloe. The feed conversion ratio was significantly (P£0.05) improved in broiler chicks fed diet incorporated with 1% giloe (T2). The performance index was significantly better in T2 and T3 compared to other groups. During finisher phase (22-42 days), the feed conversion ratio was significantly better in T2 and T6 compared to other groups. Performance index was significantly higher in T2 incorporated with 1% giloe. During the whole experimental period (0-42 days), incorporation of 1 % giloe improved broiler performance in terms of body weight, weight gain, feed conversion ratio and performance index. The average body weight gain of T1, T2, T3, T4, T5 and T6 were 1408.8, 1580.2, 1540.3, 1517.2, 1474.4 and 1551.0g, respectively. It can be concluded that giloe and/or cinnamon in combination can be fed to broilers to improve growth performance.

This study was to evaluate the effect of chamomile alcoholic extract on performance, some blood parameters and intestinal characteristics of broiler chicks. A total 320 one day old Cobb 500 broiler chicks were randomly divided into 4 treatments. Treatments were further divided into 4 replicates. Chicks were fed a basal diet as control group, basal diet with 0.3% chamomile extract (S1), basal diet with 0. 5% chamomile extracts (S2) and basal diet with 0.7% chamomile extract (S3). The experiment was carried out of 42 days. Feed intake FI and body weight gain BW was calculated for estimation of feed conversion ratio FCR. At the end of experimental period (42 days), to determine carcass traits and other parameters, 2 birds form each replicates were slaughtered. Additionally, the blood serum samples were subjected to biochemical analysis. For determination intestinal characteristics, small intestine tissues were collected. Data from this study showed that improvement of body weight gain and feed conversion were found in chamomile extract groups (P<0.05). There were significant differences between carcasses traits in treatments feed by chamomile extract. As result reveled from this study serum triglyceride, cholesterol LDL decreased in groups fed by chamomile alcoholic extract and HDL increased significantly (p<0.05) instead. In addition villus height decreased in S1and S2 groups. An increasing crypt depth was seen on S2. According to these data villus widths, epithelium layer and goblet cells increased by using chamomile extract specially by using S2. In conclusion we could demonstrate that chamomile alcoholic extract may be used as ingredient in broilers ration without harming effects on carcass characteristics, blood biochemical parameters, and intestinal morphology of Ross 308 broiler chicks.

Ross 308 broiler chicks (n = 240) aged 1 day were assigned to five groups for eight replicates (six chicks for each) (3♂ and 3♀). Basal dietary groups were supplemented by 2000, 4000, and 6000 mg/kg cinnamon (CN) for 21 days. Basal diet alone was used as a negative control, and basal antibiotic diet (Colimox) was used as a positive control. At 10, 14, and 21 days of age, chicks that received 2000 mg CN and Colimox had a higher body weight, resulting in an increase in body weight gain. CN also resulted in the maximum improvement in the feed conversion ratio and feed efficiency over 1–21 days at the level of 2000 mg/kg. At days 10, the maximum relative breast weight was 2000 mg/kg of CN. Mean serum albumin concentrations, duodenal villus height, and goblet cell density increased (p < 0.05) by 2000 mg/kg of CN, and mean serum globulin and total protein concentrations and crypt depth increased (p < 0.05) by 6000 mg/kg of CN compared with control. Increased cecal Escherichia coli number was CN dose-dependent. In conclusion, dietary inclusion of 2000 mg/kg CN can be applied as an alternative to in-feed antibiotics for broiler starter diet.

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.

This study evaluated the effects of feed additives on the growth, blood biochemistry and intestinal health of broiler chicks. A total of 378 of broiler chicks (Ross 308) were randomly allotted to seven groups. Chicks were fed a basal diet with 0.0 (control negative), 0.0 (control positive), 0.1, 0.5, 0.12, 0.5 + 0.12 and 0.2 g Kg−1 of Maxus, CloStat, Sangrovit Extra, CloStat + Sangrovit Extra and Gallipro Tech, respectively for 35 days. After 15 days, the chicks were inoculated with Clostridium perfringens. All feed additives were found to enhance growth performance and feed efficiency. The best feed conversion ratio was found in the Negative Control, CloStat + Sangrovit Extra and Gallipro Tect groups, respectively. A notable increase in villus length, total villus area, small intestine weight, ilium weight and total lesion score was found in chicks supplemented with Bacillus subtilis. Besides, the dietary inclusion of phytobiotic compounds showed potential in reducing the serum Alanine aminotransferase (ALT) concentration and increasing the glucose levels. All intestine and liver histopathological signs were reduced in chicks fed a probiotic-supplemented diet. Our findings indicate that supplementation with probiotics and phytobiotics alone or in combined form can be used to enhance performance, intestine health and blood constituents against C. perfringens infection in broiler chicks.

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.

The effect of replacing an antibiotic growth promoter in the diet with a probiotic on growth performance, carcass characteristics and nutrient retention was studied in broilers (Vencobb 430) fed with and without meat cum bone meal (MBM). This experiment which lasted for 42 days consisted of six dietary treatments viz., basal diet (BD), basal diet with MBM (MBM), basal diet with antibiotic (AB), basal diet with probiotic (PB), basal diet with MBM and antibiotic (MBM+AB) and basal diet with MBM and probiotic (MBM+PB). Three-hundred, day-old chicks were randomly allotted in the beginning to these six groups. Body weight gain, feed intake and feed conversion ratio were significantly (P less than 0.05) affected at 4th week of age. Overall, highest body weight gain was recorded in birds fed with AB and PB. Inclusion of probiotic in MBM also showed improved body weight gain when compared to MBM group. Highest feed intake and feed conversion ratio was recorded with AB and PB groups. Birds supplemented with MBM+PB showed improved feed intake and feed efficiency when compared to MBM+AB and MBM diet supplemented groups. Higher dry matter, crude protein, calcium and phosphorus retention (P less than 0.05) was observed in birds supplemented with PB or AB in diet without MBM when compared to their control. In MBM supplemented groups addition of PB or AB improved crude protein retention. Birds supplemented with PB or AB with or without MBM showed a significant (P less than 0.05) increase in thigh yield and a non significant reduction in fat yield when compared to their control groups.
