BACKGROUND A pilot clonorchiasis control project was implemented to evaluate the efficacies of various chemotherapy strategies on prevalence, incidence and re-infection in Heilongjiang Province, China. METHODS AND FINDINGS Seven intervention groups (14,139 residents, about 2000 in each group) in heavily or moderately endemic areas were subjected to repeated praziquantel administration from 20...

The classic episode of biological invasion: Cochliomyia macellaria (Fabricius, 1775) versus Chrysomya megacephala (Fabricius, 1794) (Diptera: Calliphoridae) - evaluation of the biotic potential. The biotic of the native fly Cochliomyia macellaria and the exotic Chrysomya megacephala was compared, through the reproductive capacity and longevity. The experiment took place in a climatized chamber,...

This study aims to analyze the Break-Even Point of Backyard laying hens business in Sidenreng Rappang Regency. research was conducted Bulo Village, backyard farm. from February April 2020. In this used a case study, results are not generalized. The total profit earned by these people's farm is IDR 137,717,244. For price 37,000 eggs, it will reach BEP at 1,617,723/ egg, 1,436,727,272 with egg 88...

Th e aim of the present trial was to study the eff ect of two diff erent dietary phosphorus (P) levels on the laying performance in long-term (17 months) egg production and egg shell quality in terms of strength and thickness from the 7th to 17th month of laying. In case of eggshell quality parameters the time eff ect as well as the interaction between dietary P levels and time were also examin...

abstract  introduction: this experiment was conducted to study the effects of different levels of flaxseed (0, 5, 10 and 15% of diet) and copper (in the form of cupric sulfate pentahydrate, 0 and 250 ppm of diet) on fatty acids and cholesterol in egg yolk of laying hens. methods: a total of 128 white leghorn layers aged 50 weeks were used in a factorial design and randomly assigned to 8 treatme...

s of papers 19 series were fed to the same strain of layers starting at 31 wk of age. Broken line regression analysis provided the following isoleucine estimates (g/day): Series 1 egg production, 0.46; Series 1 egg mass, 0.58; Series 2 egg production, 0.52; Series 2 egg mass, 0.50.

We used a split-plot design of five diets: control (corn-soy) with 3.8% Ca, 10% flaxseed with 3.8% Ca, 10% flaxseed with 4.5% Ca, 10% flaxseed with 3.8% Ca and 22,000 IU vitamin D3/kg, and 10% flaxseed with 4.5% Ca and 22,000 IU vitamin D3/kg, and two strains of birds, DeKalb Delta (DD) and Hy-Line W-36 (HL), to evaluate long-term effects of flaxseed supplementation on egg production parameters...

Control of Delia radicum (cabbage maggot) in field collards (Brassica oleracea) was compared after one or two applications of entomopathogenic nematodes, Steinernema carpocapsae (All strain) and Heterorhabditis bacterophora (HP88 strain), a single application of granular chlorpyrifos, and a water-only treatment. Nematodes were applied with a sprayer during the egg stage of first-generation D. r...

In South Asian countries, the lucrative production of peaches has been seriously threatened by an assortment biotic stresses especially nematodes. This situation compromises achievement sustainable development goals (SDGs) related to food security and zero hunger. Recently under changing climate, root-knot nematodes genus Meloidogyne have emerged as most damaging phytopathogenic nematodes, whil...

A procedure for extracting eggs of Meloidogyne spp. from soil was developed by modifying and combining certain existing techniques. Egg masses were elutriated from the soft, gelatinous matrices of the egg masses were dissolved, and the dispersed eggs were stained to facilitate counting. Data on egg population densities thus obtained facilitate the study of population dynamics of Meloidogyne spp...
