Published: May 2020

Mycotoxins contamination of animal feeds remains a great concern for animal feed safety, public health and economic significance. It may occur in various foods and feeds stuffs from agricultural commodities to finished foods and feeds of animal. Hot, humid weather and late harvesting of grains favored the mold and fungal growth in cereal crops. There are around 400 types of mycotoxins in which aflatoxin, deoxyinalenol (vomitoxin), fumonisin, zearalenone and ochratoxins are important for animal and human foods. However, presence of mold or fungi in the grains does not mean that mycotoxins are present in feeds or foods. The acceptable level of aflatoxins, deoxyinalenol (vomitoxin), fumonisin, zearalenone and ochratoxins are in livestock feeds are 20 ppb, 10 ppm, 5 ppm and 3-10 ppm and 3-20 (μg/kg) respectively. Mycotoxins can be found in contaminated cereal grains, straw and silage. The most detrimental effects of mycotoxins are hepatic, digestive, immunological, reproductive disorders, teratogenicity, nephrotoxicity, edema and carcinogenicity etc. of animal and human being. Adsorbents and activated charcoal in animal feeds bind the toxic substances. There are some regulations but not in all countries aimed to prevent and control mycotoxins in industrial processed foods and animal feeds but not in locally processed ones. A number of strategies in some countries for preventing mycotoxins have been mobilized but the awareness for implementation is very weak. Mass media can play an important role to build awareness to mycotoxin.

Authors: Monira KN , Hussain SS 
Published: May 2020

Poultry contributes the largest parts of animal-source foods. The International Food Policy Research Institute (IFPRI) has estimated that by year 2015, poultry will account for 40% of all animal protein. Indigenous chicken have a capacity to resist disease, able to utilize low quality feeds and their products are preferred by consumers. Their views were collected to indigenous chicken production scenarios and their characteristics and to synthesize the information for gathering knowledge. The review areas were all over Bangladesh but our studied areas were Baraigram, Natore; Sarail, Brahmonbaria and Bandarban Hill tract and genotypes were Indigenous, Aseel and Hilly chicken. The production or management system was backyard scavenging and semi-scavenging type for Indigenous, Hilly and Aseel female chicken but for Aseel male it is used intensive system for breeding program; which was characterized by small flock size.The average number of chicken per house-hold was almost same in Baigram and Sarail (7.93±4.46 and 7.69± 2.75); but lower in Bandarban Hill district (5.11± 1.78). Indigenous, Aseel and Hilly chickens have a large morphological variation. The percent of plumage color of Indigenous chicken was 35% black brownish, 30% brown with black strip, completely black 30% and golden red 5%; in Aseel chicken was as 45% golden red, 30% black brownish, completely black 25% and in Hilly chickens have 50% black brownish, 45% brown with black strip and 5% black plumage color. 90% of indigenous chicken have yellow shank while 10% black shank. All the Aseel chickens have yellow shank. The shank color of Hilly chicken was as 50% yellow, 39% white and 11% black. The study revealed that indigenous chicken and Hilly chicken laid mainly white colored eggs and Aseel chickens laid mainly light brown egg. Feeds were not usually supplemented in all three genotypes reared under scavenging system. Chickens pick up grains such as rice, vegetables, green grass, insect, earthworm etc. from the yard, as chickens have reared under scavenging system. Different types of housing were used for chickens in the selected sites. Approximately 30%, 40% and 60% of farmers kept chickens in their living houses in cases of Indigenous chickens, Aseel and Hilly chicken, respectively. No farmer used artificial lighting for the chickens. So, the study was performed to review indigenous chicken production scenarios may serve as an important base of Ph.D research and may help to take proper planned to conserve of these three genotypes.

Authors: Giasuddin M , Ali MZ , Karim MR , Hassan MZ , Hasan M , Islam E 
Published: May 2020

Avian influenza virus (AIV) is a pandemic thread and this year 2018 is passing the century of Spanish flu (H1N1) of 1918 when the world approximately 50 million human deaths occurred worldwide. About 1.7 million peoples become died in over Asia from 1957 to till now by the name of Asian flu (H2N2) at 1957 and Hong Kong flu (H3N2) at 1968. In Bangladesh, since first identification of Highly Pathogenic Avian Influenza (HPAI) at 2007 poultry industry faces outbreaks at a significant level in every year although human infection is uncommon. The infections spreading among all major avian species like chicken, duck, turkey, quail. On the other hand it is reported that the infection is spreading among wild birds like house crow, migratory birds and wild animals also. During first isolation the virus were in clade 2.2.2 but after several mutations over 11 years now it becomes under clade 2.3.2.1a and circulating in environment. Government of Bangladesh decided to vaccinate against AIV in 2012 with two killed and one vector vaccine to combat the AIV that brings a satisfactory result. But from the couples of years again the incidence of AIV becomes very high and ongoing researches like sink surveillance shows 50-90% live bird markets of Dhaka and Chattagram districts are infected. To combat the AIV it is recommended that farms should have to ensure the good quality vaccine with good farm biosecurity practice along with conventional stamping out program.

Published: May 2020

A prevalence study was conducted to observe both ecto-and endo-parasitic (gastrointestinal) infection throughout one year surveillance. The study was conducted from July 2014 to June 2015 through Parasitology Laboratory, BLRI, Savar, Dhaka. The study considered age of cattle, season and type of parasitic infestation. In the study area total number of cattle population was 2000 in which 500 fecal and 200 ectoparasitic samples was collected considering three respective seasons like rainy, summer and winter. The fecal samples were examined by direct smear method followed by McMaster counting techniques and examine under microscope. After collection of samples within 24 hours all sample were tested by preserving at 40C temperature. In clinical observation, the overall prevalence of endoparasitic (gastrointestinal) infection was 68% and ectoparasitic infection was 60%. Prevalence of endoparasite was more frequent in rainy season (52.65%) followed by summer (27.05%) and winter season (20.29%) whereas prevalence of ectoparasite was more frequent in summer (39%) followed by rainy (13.5%) and winter (7.5%) season. The parasitic prevalence load was low in winter season. In endoparasitic infection, the higher prevalence of Paramphistomum spp. (20%) was found in rainy season whereas Haemonchus spp. (14%) and Toxocara spp. (12%) were higher in summer. In cattle, prevalence of Paramphistomum spp. (25.14%) and Haemonchus spp. (18.58%) was higher in adult cattle (above 6 months), whereas prevalence of Toxocara spp. (36.67%) and Coccidial oocyst (23.33%) was higher in calf (under 6 month) than adult animal (above 6 months) of age. The overall prevalence of ectoparasite was 60% and tick infestation was highest (22.5%) followed by lice (17.5%), mange (12.5%) and maggot fly (7.5%). High humidity (above 70%) and temperature provoke high endo- and ecto-parasite infection in the environment and infect cattle as well as other livestock species.

A study on value added dairy products and availability of milk, meat and egg at consumers’ level in selected areas of Bangladesh
Authors: Uddin MT , Islam MM , Nasrin M 
Published: May 2020

The goal of the study was to analyze the different actors involved in the dairy products value chain with their value addition activities and estimate the demand for livestock products through measuring the availability of milk, meat and egg at individual level. With this goal, the study was conducted in four districts namely Sirajganj, Bogra, Rangpur and Narsingdi which were selected purposively for this study based on concentration of dairy farming and the presence of dairy processing plants/companies. The simple random sampling technique was followed to select a total of 240 from six types of stakeholders/ actors i.e., input suppliers, dairy farmers, milk traders, processing plants/companies including their branches/agents, credit organizations and service providers, and consumers of livestock products. Data and information were analyzed by using descriptive statistics, mathematical techniques, enterprise analysis, SWOT analysis and value chain analysis followed by graphical presentation. Cost of milk per litre was highest in Narsingdi (Tk. 25.33) and lowest in Sirajganj (Tk. 19.66). Dairy farmers in Narshingdi derived highest net return per cow per day (Tk. 109.48). Investment in dairy farming was highly profitable since BCR per day per cow in all the districts were more than one. Collection point/processing plants added highest value (35.5%) to a product followed by farmers (25.2%), milk traders (28.3%) and retailers (11.0%). The availability of milk, meat and egg was higher in all the study areas than the national average. The impact of price and income on quantity demand was statistically significant for all the products. The demand for milk and egg was price elastic whereas demand for meat was price inelastic. On the other hand, the demand for livestock products was found as income inelastic. However, in spite of various problems and threats, there is a great export potential for value added dairy products along with satisfying the unmet consumer demand in the domestic market for such products.

A feeding trial was conducted on 21 crossbred (Local×Friesian, Local×Sahiwal, Sahiwal×Friesian) calves of around one week age for a period of 70 days with the objective of evaluating effects of probiotic on growth performances of calves. Calves were selected and distributed equally into three groups maintaining equal sex ratio in each group, namely the farm practice (FP), control and probiotic groups. The calves were fed on milk as 12% of their live weight up to 14 days and then 10% milk of their live weight up to 70 days of age and wheat bran was supplied to the calves from 50th day at the rate of 250g/calf. The calves of probiotic group werefedaprobiotic mixture containing lactic acid bacteria (LAB) at 0.5 g /d. The data of feed intake and growth for all groups were recorded up to 35 days and then up to 70 days for probiotic and control groups. The calves under probiotic group were achieved 82.8% and 74.5% higher gain (P<0.05) than that of FP and control group, respectively and feed conversion ratio was observed significantly (P<0.05) better in probiotic group (1.83) than that in FP (3.41) and the control group (3.50) up to 35 days of trial. However, no significant differences were found in average live weight gain and feed conversion ratio between probiotic and the control groups (1.99 vs 2.07, respectively) up to 70 days of the trial. Average counts of E. coli were lower in probiotic group than that in the control and FP. The incidence of diarrhoea in probiotic fed group was found 3 and 13 times lower compared to FP and the control group, respectively.
