This study was conducted to determine the effects of adding ethanol extract of propolis (EEP) and cumin essential oil (CEO) to diets of broiler chicks on the performance, blood parameters, immune response and carcass traits. A total of 240 day-old Ross-308 broiler chicks were randomly allocated to four treatments with six replicates and 10 birds in each replicate in a completely randomized desi...

In order to evaluate the effects of chlorella on broiler performance and immune system, an experimentwas performed by using 80 ROSS 308 male broiler chicks. The experiment was accomplished incompletely randomized design including 5 treatments with 4 replication and 4 observations in eachreplicate. The basal diet was based on corn-soybean meal (control) and without any additives. Agraded level o...

introduction corn and wheat are the grains most routinely used in commercial poultry diets. for consumption of these cereals, there are a competition between humans and mono-gastric animals. due to corn crop limitation in iran, approximately 50% of the corn required for poultry nutrition is supplied through imports. since triticale is more resistant to various diseases, dry weather and in simil...

The effects of feeding finishing diets containing whole corn with no roughage on performance and carcass characteristics of feedlot steers were evaluated in 6 trials conducted at commercial research facilities (Bos Technica Research Services Inc., Salina, KS) in the Southern Plains of the United States. One hundred and two feedlot pens containing 6,895 steers were represented. All trials were d...

In this study, we compared corn gluten hydrolyzates, BCAAs, and leucine for their effects on body weight reduction in high fat-induced obese rats in order to determine the major active components in the corn gluten hydrolyzates. After obesity was induced for 13 weeks with high fat diet, the overweight-induced SD rats (n = 64) were stratified according to body weight, randomly blocked into eight...

A series of 3 experiments were conducted to determine the in vitro and in situ disappearance, preference, and performance of steers consuming increasing concentrations of a novel feedstuff called algae meal (ALG). In Exp. 1 and 2, 3 ruminally cannulated steers (998 ± 103 kg BW) and 4 treatments were utilized: a dry-rolled corn-based diet (CON), or 15% ALG (A15), 30% ALG (A30), or 45% ALG (A45) ...

A complex system of economic and political policies has led to the mass over production of corn in the United States. As a result of this overproduction, we now see corn in the majority of processed foods as well as animal feeds, in particular cattle feed. However, evolutionarily cattle are adapted to pasture diets not corn-based diets. Cattle have complex digestive systems, consisting of the r...

The objective of this experiment was to measure the apparent total tract digestibility (ATTD) and the retention rate of Zn, Cu, Mn, and Fe in pigs fed either inorganic or organic sources of Zn, Cu, Mn, and Fe. The experimental design was a randomized complete block design with a 2 × 3 factorial arrangement of treatments. There were 2 types of diets (corn grits-based or corn-soybean meal [SBM]-b...
