Glyphosate-resistant corn and soybean are grown in rotations in the Midwest, including Nebraska. Volunteer corn is a problematic weed in soybean fields because it causes harvest problems, reduces yield and seed quality, and potentially harbors insects, pests, and diseases. Several pre-packaged herbicides have been registered in soybean in recent years, but response of volunteer corn to these he...

The aim of this model study was to investigate how selected gut functions and serum lipid profile in rats on high-fat diets differed according to the type of fat (saturated vs. unsaturated) and carbohydrate (simple vs. complex). The experiment was conducted using 32 male Wistar rats distributed into 4 groups of 8 animals each. For 4 weeks, the animals were fed group-specific diets that were eit...

Experiments were conducted with growing and finishing swine to evaluate the effectiveness of various amino acid additions to low-protein corn-soybean meal diets. Two feeding experiments were conducted with growing swine each including a 16% protein positive control diet. In the first, a 14% protein diet served as the negative control while in the second trial it was a 12% protein diet. Amino ac...

Two experiments were conducted to determine the effects of dietary supplementation of exogenous enzymes on growth performance, apparent total tract digestibility (ATTD) of energy and nutrients, blood metabolites, fecal VFA, and fecal ammonia-N in growing pigs (Sus scrofa) fed a corn (Zea mays L.)- and soybean [Glycine max (L.) Merr.] meal (SBM)-based diet. In Exp. 1, 240 growing barrows (initia...

This study was conducted to evaluate the effects of algal fucoidan and probiotic Bacillus subtilison growth performance, blood metabolites and intestinal morphology in broiler chickens. A total of 250 one-day-old Ross 360 male broiler chickens were randomly distributed into 5 treatments (6 replication pens/treatment) and reared for 42 d. The 5 dietary treatments were as follow: 1) a corn-soybea...

the aim of the present study was to assess whether near infrared reflectance spectroscopy (nirs) and regression equations are the practical and accurate approach of nutritional assessment of common feedstuffs. therefore two experiments were conducted to study the effect of amino acid determination methods on broiler performance. in experiment i, two hundred thirty four male ross broiler chicks ...

Two trials of similar experimental design were conducted to assess the effects of various dietary enzymes on energy digestibility of diets high in distillers dried grains with solubles (DDGS) for broilers. A 2 × 4 factorial arrangement of treatments was used in which a cornsoybean meal control diet and a diet with 30% DDGS were supplemented with 2 different commercial enzyme products. In additi...

Ninety-six (Finnish Landrace x Dutch Landrace) reproductive sows were used at parities 1, 3, 5, and 7 + 8 from d 107 of gestation to d 21 of lactation to investigate the effects of diet and parity on apparent total tract digestibility (ATTD). Animals were randomly assigned to one of four dietary treatments. Dietary treatments were 1) a P-deficient (1.1 g digestible P [dP]/kg) Dutch semipractica...

this experiment was conducted to determine the effects of myrtle essential oil (meo) on growth performance, carcass characteristics, antibody titer and blood parameters of broiler chickens. a total of 200 ross 308 broiler chickens were allocated to five dietary treatments with four replicates of 10 birds each. dietary treatments were prepared by formulating a corn-soybean meal-based diet free o...
