among fungi, species of the genus paecilomyces are considered as promising biological control agents with high potential to reduce root-knot nematode (rkn) and other nematode populations. in this research we investigated a soil hyphomycetes, paecilomyces marquandii and its pathogenicity on eggs of rkn in vitro. in greenhouse test, root weight, plant length, fresh weight and dry weight of plants...

objective: the purpose of the study was to evaluate the production of antibodies in serum as well as egg yolk raised against s. typhimurium and the cross-reactivity of this antibody with other enteric bacteria. materials and methods: white egg–laying hens were immunized with s. typhimurium, heat-killed whole cell, in freund's adjuvant. immunization was done with 107 conlony forming unit (cfu) o...

introduction breeding quail and quail egg industrial production because of the high nutritional value of these products has been developing these years. considering the high demand and economical production, further development in the future is predicted. in order to design and effective utilization of the equipment for transportation, separation, packaging and storage, the physical and mechani...

BACKGROUND Embryonated chicken eggs have been used since the mid-20th century to grow a wide range of animal viruses to high titers. However, eggs have found so far only limited use in the production of recombinant proteins. We now describe a system, based on a Sendai virus minigenome, to produce large amounts of heterologous viral glycoproteins in the allantoic cavity of embryonated eggs. RE...

The quail raising in Brazil has increased through the last years and the incubation procedures are important to maintenance and improvement of quail egg production. To obtain a sufficient number of eggs to fill an incubator, eggs are usually accumulated in storage over a period from 1 day up to 3 weeks before incubation. The objective of this research was to verify the effect of egg storage on ...

A study was carried out to examine the hatchability of guinea fowls eggs and performance of keets under the traditional extensive system. A short questionnaire to ascertain production scope and management practices were administered to a total of ten farmers; five farmers from each of two communities, using purposive sampling. In order to establish some actual production indices, data was colle...

Many retailers have expanded and diversified their private label food product assortment by offering premium-quality products such as organic products. With price being identified the major barrier for purchases, could be a suitable more affordable alternative many consumers. While numerous studies examined consumer preferences food, very few incorporated concept of labels. This study addresses...

Broiler parent stock of 7851 Cobb-500, 8388 Ross and 8745 Hubbard-Hi-Yield were reared in controlled (slated cum floor system) house to determine the egg production performance, fertility and hatchability. A total of 151200 hatching eggs of Cobb-500, Ross and Hubbard-Hi-Yield broiler strain were collected and set in the incubator in 10 batches having 15120 eggs in each batch and 5040 eggs in ea...
