The effects of an increasing proportion of crushed linseed (CL) in combination with varying forage type (grass or corn silage) and forage to concentrate ratio (F:C), and their interactions on milk fatty acid (FA) profile of high-producing dairy cows was studied using a 3-factor Box-Behnken design. Sixteen Holstein and 20 Swedish Red cows were blocked according to breed, parity, and milk yield, ...
This study was conducted to evaluate the effects of inoculation of homo-fermentative lactic acid bacteria(LAB) on ensiling characteristics and nutritive value of low dry matter corn silage (LDMCS). Corn foragewas harvested at milk stage (22.8 ± 0.9% DM), chopped at theoretical length of cut (TLC) 2.5 cm, and stored in eighteen 3.8 L mini silos for each treatment. The following treatments were u...
Ruminant animals are carriers of Escherichia coli O157:H7, and the transmission of E. coli O157:H7 from cattle to the environment and to humans is a concern. It is unclear if diet can influence the survivability of E. coli O157:H7 in the gastrointestinal system or in feces in the environment. Feces from cattle fed bromegrass hay or corn silage diets were inoculated with E. coli O157:H7, and the...
the replacement of corn silage with varying levels of ammonia gassed wheat straw on performance, digestibility, fermentation parameters, chewing activities, blood metabolites and profitability of holstein heifers have been evaluated. fifteen holstein heifer with 9-10 months of age were assigned in a completely randomized design with 3 treatment as 1) 36% corn silage, 2) 18% corn silage and 18% ...
Estimating the available energy in corn silage provides a unique challenge because the silage contains variable proportions of grain and stover, each of which can differ in availability due to chemical composition and physical form. The objectives of this study were to investigate relationships among chemical components and their relationships with in vitro disappearance of ground and unground ...
The disappearance of dry matter (DM), crude protein (CP), and amino acids (AA) in steers after rumen incubation and intestinal passage of alfalfa hay, barley hay, corn silage, barley grain, corn grain, wheat bran, meat meal, fish meal, cottonseed meal, and soybean meal were measured in 3 steers using a mobile nylon bag technique. Ruminal degradation of individual AA differed between feedstuffs....
The aim of this study was to investigate the effect of bacterial inoculation on the fermentation and aerobic stability of corn silage and on the dry matter degradability and milk composition when fed to sheep or cows. Four male sheep were selected to measure dry matter degradability of uninoculated (UCS) and inoculated (ICS) corn silage. Milk composition was measured for 22 Holstein cows, separ...
Forty-eight Polish Landrace pigs (initially 32.43 ± 0.70 kg live weight) were assigned to a 2 × 2 × 2 factorial arrangement in order to assess the effects of the rearing system (outdoor v. indoor), diet (with corn grain silage v. without corn grain silage) and gender (barrows v. gilts) on performance, carcass traits, meat quality and intramuscular collagen (IMC) characteristics. During the tria...
The aim of present study was to assess the effects of individual various essential plant oils on chemical composition, aerobic stability and fermentation characteristics of corn silage and in vitro rumen fermentation and methane emission using gas production technique. Whole crop corn was harvested and ensiled in laboratory scale tubes (4±0.25 kg) for 45 days. Treatments consisted of either cor...
Alfalfa hay was steam heated for an average of 47 min at 100 to 110°C; net ruminal protein escape (total escape minus ADIN x 6.25), estimated in vitro, was 50% versus 29% for control hay. Heating increased ADIN content from 4.6 to 15.3% of total N and increased NDF from 43 to 53% of DM. In trial 1, 14 cows averaging 81 DIM and 30 kg/d of milk were fed, in a switchback design, diets containing 1...
