The pea leaf weevil, Sitona lineatus L. (Coleoptera: Curculionidae), has recently emerged as an important pest of field peas in the Canadian prairies. Systemic seed-coated insecticides may provide a tool for the integrated pest management of this pest. Therefore, several controlled assays were performed in order to determine effects of a recently registered neonicotinoid, (thiamethoxam) on S. l...

The female reproductive tract is commonly referred to as oviduct in birds. The oviduct is a highly convoluted muscular duct, concerned with the transport of the ovum away from the ovary, with fertilization of the ovum and by the deposition of albumen, membranes and shell on to the ovum to form the finished egg [1]. Reproductive diseases in poultry causes high morbidity (35%), mortality (15%) an...

Egg-burying reptiles need relatively stable temperature and humidity in the substrate surrounding their eggs for successful development and hatchling emergence. Here we show that egg and hatchling mortality of leatherback turtles (Dermochelys coriacea) in northwest Costa Rica were affected by climatic variability (precipitation and air temperature) driven by the El Niño Southern Oscillation (EN...

a 3*2*2 factorial experiment was conducted to study the effect of feeding whole wheat (0, 10, and 20%), a microbial enzyme source (arabino-xylanase based enzyme for wheat at 0% and 0.1%) and 0% or 1% insoluble grit (number 3 layer size) on the performance of white leghorn hens at 19 to 54 weeks of age. each dietary treatment was replicated four times with ten hens, housed two to a cage, eac...

The objective of this experiment was to compare the effects of 2 sources of phytase on performance of commercial Leghorns fed corn-soy diets. Seven diets were fed to Hy-line W-36 hens (n = 840; 8 replicates of 15 hens per treatment) from 21 to 33 wk of age. The treatments consisted of a control diet containing 0.38% nonphytate P (NPP) and a 2 x 3 factorial arrangement of 2 dietary NPP concentra...

This study aimed to evaluate egg production systems within the scope of sustainability criteria under Turkey conditions. A standardized data approach was used measure and compare systems. The covered a one-year egg-laying cycle 24 farms including conventional cage, organic, free-range Hens in cages had higher lower feed intake compared hens organic highest mortality found while lowest cage syst...

to evaluate the effect of metarhizium anisopliae and trichoderma harzianum on root knot nematode (meloidogyne javanica) in tomato, experiments was performed under controlled as well as greenhouse conditions. volatile and non-volatile tests showed that there is no inhibitory effect against every one of each biocontrol agents. on the larval mortality and inhibition of egg hatching, a laboratory t...

A study was conducted to examine the effect of yeast culture residue (YCR) on the suppression of aflatoxicosis in broiler breeder hens. One hundred twenty, 35-wk-old, Cobb broiler breeder hens of the same cross were fed diets supplemented with aflatoxin (AF) (0 or 3 mg/kg) and YCR (0 or 2 lb/ton) singly and combined in a 2 × 2 factorial designed experiment. The birds were randomly assigned to p...
