Growth Performance Characteristics of Cockerel Chicken Fed Diets containing Ginger Rhizome and Garlic Bulb powder

The use of antibiotics in poultry production has raised global concern due to health risk associated with its residues in poultry products. A study was conducted to assess the growth performance characteristics of cockerel fed ginger and garlic based diets for a period of 12 weeks. A total of 180 day old Isa white cockerels were randomly allotted to 4 experimental treatment diets. Each dietary treatment was replicated 3 times with 15 chicks per replicate in a completely randomized design. Diet one had 0% ginger rhizome and garlic bulb powder (T1), diet 2 had 2% ginger rhizome powder (T2), diet 3 had 2% garlic bulb powder (T3) while diet 4 had 2% mixture (1:1) of ginger rhizome powder and garlic bulb powder (T4). The weights were measured and weight gain calculated on weekly basis. In addition, the feed intake and feed conversion ratio were measured and calculated on weekly basis. At starter phase, average initial weight, average final weight, average weekly feed intake and average daily feed intake were not significantly (P>0.05) affected by the dietary treatments. However, Feed conversion ratio (FCR) was significantly (P<0.05) highest (2.09) among birds placed on T2 while the lowest mean value of 1.30 was recorded in T3. At finisher phase, the average initial weight, average weekly feed intake, average daily feed intake and FCR were not significantly (p>0.05) affected by the experimental diets. However, birds fed T4 had the highest (P<0.05) mean value of average final live weight (1796.67g) while the least value (1553.33g) was obtained in birds fed T3. The average daily weight gain were significantly (p<0.05) highest 37.14 g T2. It was concluded that ginger and garlic powder can be used successfully in cockerel diets at 2 % level of inclusion to enhance growth performance characteristics especially at finisher phase.

CLOVE-SEED SIZE AND HEALTH AND PLANT SPACING ON THE VIABILITY OF GARLIC CROPS

ABSTRACT Garlic is a vegetable that has a high economic importance for Brazil. However, despite increases in garlic bulb production in the last years, Brazil is still dependent on imported garlic to meet the national demand. Thus, proper management practices and the use of virus-free clove-seeds are promising alternatives to ensure a high productivity and profitability. Thus, the objective of this work was to evaluate production characteristics and profitability of conventional and virus-free garlic crops as a function of different clove-seed sizes and plant spacings. Two experiments were conducted simultaneously, using virus-free and conventional garlic plants in Portalegre, state of Rio Grande do Norte, Brazil, in a randomized block experimental design, with four replications. The treatments were arranged in split-plot, with the clove-seed size (large and small) in the plots, and the spacing between plants (7.5, 10.0, 12.5, and 15.0 cm) in the subplots. The combination between the use of virus-free clove-seeds, large clove-seed size, and spacing of 12.5 cm between plants resulted in the highest commercial bulb yield and net income, R$ (BRL) 85,151.00 ha-1. The use of large clove-seeds and spacing of 7.5 cm between plants are recommended for conventional garlic crops.

Management of Anthracnose Disease of Aloe vera in Bangladesh

Aims: To identify the causal organisms of anthracnose disease of Aloe vera in Bangladesh and to manage this disease in field condition. Study Design: The experiment was designed by Randomized Complete Block Design (RCBD) with three replications. Place and Duration of Study: The field experiments were conducted in Natore, Bangladesh and the laboratory experiments were carried out at the Department of Plant Pathology, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh from January, 2017 to December, 2018. Methodology: The causal organism Colletotrichum gloeosporioides was isolated by tissue plating method and identified based on morphological and cultural characteristics and that was confirmed by pathogenicity test. Infested farmer’s fields were selected in rainy season under natural epiphytic condition to evaluate the efficacy of eleven treatments. Results: Among the treatments, Bordeaux mixture gave best result against this disease. Moreover, Tilt 250 EC and Folicur 25 EC and Garlic bulb extract showed better effect against the disease than the other treatments. Lime also has moderate effect against anthracnose disease of A. vera. In 2017, after 4th spray, the lowest incidence was recorded in Bordeaux mixture (58.33%) which was statistically identical with Folicur (64.58%), Tilt (64.58%) and Garlic bulb extract (66.67%). Similarly, the lowest disease severity was found in Bordeaux mixture (3.55) followed by Folicur (5.67%), Tilt (6.67%) and Garlic bulb extract (7.67%). Similar result also found in 2018. After 4th spray, the lowest incidence was recorded in Bordeaux mixture (38.58%) which was statistically identical with Lime (41.66%) and Garlic bulb extract (45.83%). Similarly, the lowest disease severity was found in Bordeaux mixture (0.20%) followed by Lime (0.25%) and Garlic bulb extract (0.36%). Conclusion: Garlic bulb extract could be used as eco-friendly approach. Moreover, use of Bordeaux mixture is better than the traditional use of lime. From chemical pesticides, Tilt 250 EC and Folicur 25 EC could be used for controlling the disease as the last option.

Agronomic Biofortification of Garlic through Selenium and Arbuscular Mycorrhizal Fungi Application

Garlic has a strong ability of selenium (Se) accumulation and is one of the best target crops for Se biofortification. Arbuscular mycorrhizal fungi (AMF) inoculation might enhance the nutritional qualities and the absorption ability of exogenous Se in plants. However, little is known about the exogenous Se application and AMF inoculation on garlic. Here, we evaluated the effects of different concentrations of exogenous Se on the growth, nutritional quality, and selenium enrichment of garlic. The results demonstrated that significantly higher Se content of garlic bulb was found in exogenous Se treated plants, and the Se accumulation was improved with the increasing of Se supply. Low application of exogenous Se appreciably improved the yield and the contents of soluble sugar and allicin in garlic bulbs, but the opposite was observed at high Se concentration. Furthermore, AMF inoculation significantly reduced the inhibition effect of high concentration Se on garlic. AMF supply was effective in improving the growth and nutritional indicators of garlic, which promoted the exogenous Se utilization rate when combined with 10 mg/L exogenous Se treatment. The results will provide a more theoretical basis for the production of high-quality selenium enrichment garlic.

Identification of Pathogens Causing Bulb Rot Disease on Garlic (Allium sativum L.) in Central Java, Indonesia

Garlic bulb rot disease was found from garlics (Allium sativum L.) cultivated from 2017 to 2019 by farmers in Central Java Province, Indonesia. The initial symptoms of the disease were stunted, leaf yellowing, and necrotizing to rotten bulbs. This research was conducted to determine the major causal agent of garlic bulb rot disease in Central Java. A survey was carried out in five regencies across Central Java that were major garlic-producing areas. Nematodes were isolated using water immersion methode and pathogenic fungi were isolated on Potato Dextrose Agar (PDA). Nematode identification was carried out based on the Ditylenchus dipsaci morphological and morphometric character. Seven isolates of Fusarium species were obtained from infected garlic. Identification of four chosen isolates were performed by sequencing the TEF-1α gene. The TEF sequence of isolate TB3, KK1, and KK4 showed 99% similarity with several F. oxysporum, BT3 sequences showed 98% identity with several F. solani, and all were deposited in the NCBI GenBank. Three locations were positively infected by the interaction between D. dipsaci and Fusarium sp. Based on the results of the morphological identification, parasitic nematode was identified as D. dipsaci, while based on the morphological and molecular identification isolates Fusarium were identified as F. oxysporum and F. solani, respectively, as first report causal agents of garlic bulbs rot in Central Java.

Hormonal profile and reproductive performance of male and female rabbits fed diets containing garlic bulb (Allium sativum) meal

An experiment was conducted with 24 buck and 24 doe rabbits of about 5-8 months. The animals were fed diets containing garlic flour meal to determine the effect on the hormonal profile and reproductive performance of the rabbits. The 48 rabbits were separated according to their sexes (buck and doe) and divided into four treatment groups with four rabbits consequently replicated three times in a completely randomized design. Dietary levels of 0.0, 5.0, 10.0 and 15.0% of garlic flour meal were used to formulate the diet for rabbits. At the end of this trial, different parameters on hormonal profile and reproductive performance were determined. All the parameters of hormonal profile were significantly P<0.05) different thereby maintaining similar values except luteinizing hormone which had slight value fluctuation. The highest value of testosterone and progesterone were recorded in the diet containing 15.0% garlic flour meal. Similarly, the parameters on reproductive performance exhibited significant (P<0.05) difference. Partum weight and litter weight at birth showed a higher value as garlic meal was increased. The results of this study indicated that 15.0% dietary level of garlic flour meal proved acceptable for hormonal profile and reproductive performance of rabbit.

Stimulantia Effect Of Single Bulb Garlic Extract (Allium Sativum Var.Solo Garlic) in Swiss Webster Mice

Stimulant is an agent that stimulates the central nervous system thereby increasing physical and mental abilities and minimizing fatigue. The use of synthetic caffeine stimulants of 10 mg / kg BW is known to have side effects of increasing total cholesterol and increasing LDL, therefore alternative stimulants from natural ingredients are needed. Natural materials that have been studied contain flavonoids and phenolic as a stimulant compound is a single garlic bulbs. The purpose of this study was to determine the stimulant effect of a single garlic bulbs ethanolic extract on mice from the difference in swimming time. The research experimental used Pre test and Post test control design. Sample of this research used mice which were divided into 6 groups. Group 1 pretest dose 5 g / kgBB, group 2 (negative control), group 3 (caffeine), group 4 extract dose 5g / kgBB, group 5 dose 10g / kgBB and group 6 dose 20g / kgBB. Data was analyze using one way Anova continued with Post Hoc test. The group of single garlic bulb ethanolic extract dose 20 g / kgBB had the highest stimulant effect with 222,722 minutes fatigue time difference and statistically have significant difference (p <0.05) than the negative control group. Group of single garlic bulb extract can influence the time of fatigue of mice by extending the swimming time of mice so that it has a longer fatigue time which means it has a stimulant effect
