Nitrogen (N) balance studies were conducted with male growing broiler chickens to reevaluate the lysine (Lys) requirement of a modern broiler strain (Ross 308), making use of eight diets with graded crude protein (CP) supply (6% 34% CP as-fed). Wheat, soy protein concentrate, wheat gluten, fishmeal and crystalline amino acids (AAs) were the protein sources in the experimental diets with Lys as ...

The present study was carried out to investigate the economic loss of flood victim broiler farms and also to explore the relationship between various independent variables with economic loss of flood victim broiler farms (dependent variable). The independent variables were considered as education, family size, occupation, farm size, feed sources, types of vaccine and medicine used and marketing...

The content of vitamin D in pork produced in conventional systems depends on the vitamin D concentration in the pig feed. Both vitamin D3 and 25-hydroxyvitamin D3 (25(OH)D3) are essential sources of dietary vitamin D; however, bioavailability assessed by serum 25(OH)D3 concentration is reported to be different between the two sources. Furthermore, the relationship between serum 25(OH)D3 level a...

There are few good sources of natural food folates apart from green leafy vegetables and these may have a limited potential to increase folate status because of substantial losses that can occur during cooking. Fortified foods can overcome this but are controversial because of safety concerns regarding chronic exposure to high-dose folic acid (FA; the synthetic form). The aim of the present stu...

This study was initiated to characterize urban and peri-urban sheep production systems and their economic importance in and around the towns of Debre Berhan and Dessie, Ethiopia. The study was undertaken using group discussions, structured questionnaire and personal observations. In both locations the majority of sheep producers were male household heads and predominantly traders in urban and f...

Tilapia is one of the most important groups of fish for aquaculture with an annual production exceeds two million metric tons. They have been cultured for quite a long time ago. However, their aquaculture production has been developed remarkably during the last few decades due to the increased level of intensification and cultured area. In the past, fish meal was used as a main protein source i...

This study examined the comparative utilization of 30% inclusion levels of three vegetable protein sources [Groundnut Cake (GNC); Soybean Meal (SBM) and Cotton Seed Cake (CSC)] in the diets of growing and laying Japanese quails. The findings showed no significant variations (P>0.05) on feed intake, weight gain and feed/gain ratio during the growing period among the vegetable protein sources fed...

this study was conducted to determine nutritive value of common animal feed sources in east azerbaijan province including second cutting of alfalfa hay ( n=35) and wheat straw (n=26). chemical composition and mineral contents of alfalfa hay and wheat straw were determined according to standard methods. then the average chemical compositions of these samples were compared with those of the gilan...

Many herbivorous insects feed on plant tissues as larvae but use other resources as adults. Adult nectar feeding is an important component of the diet of many adult herbivores, but few studies have compared adult and larval feeding for broad groups of insects. We compiled a data set of larval host use and adult nectar sources for 995 butterfly and moth species (Lepidoptera) in central Europe. U...

Fractional rate of degradation (kd) of fermentable nutrients in the rumen is an important parameter in modern feed evaluation systems based on mechanistic models. Estimates of kd for starch was obtained on 19 starch sources originating from barley, wheat, oat, maize and peas and treated in different ways both chemically and physically. The starch sources were fed in mixed diets together with gr...
