Two experiments were carried out to investigate i) the effects of four levels of lactic acid bacteria inoculants (LAB; 0, 2×10, 3×10 and 4×10 cfu/g fresh forage) and two physical forms of rice straw (whole and chopped rice straw) on silage fermentation quality and nutritive value of rice straw (RS) silage for lactating Holsteins and ii) the effects of the replacement of corn silage (CS) with di...

The Effect of Processing Corn Silage with Schizophyllum Commune on Chemical Composition, Ruminal Degradability and in Vitro Gas Production

The influence of corn silage feeding level was examined on eighty-three Charolais crossbred steers (389+30 kg BW). Each steer was randomly assigned to one of four diets which contained either 0, 15, 50 or 85 percent corn silage (CS) dry matter. Each ration was balanced to a 13.6 percent crude protein level. Mineral, vitamin and ionophore fortifications (monensin @ 33 ppm) were similar for each ...

The study was conducted to screen high 1,2-propanediol produced by Lactobacillus buchneri strains, isolated from baled silages stored for 1 or 2 years, and evaluate their effects on fermentation quality aerobic stability of whole-plant corn silage. In total, 31 L. strains were alfalfa, oat silages. Based growth performance acetic acid production, two 9-2 10-1, alfalfa silage, further assessed i...

Amaranth ( sp.) is a C plant adapted to poor soils and regions with limited rainfall and high temperatures. The plant is characterized by a yield of up to 85 t/ha, CP concentration of up to 28.5% of DM, and DM digestibility of 59 to 79%, which may vary depending on the species and variety. The potential of this plant as a forage source for ruminants has not been completely considered. This stud...

I arrived at UC Davis in October 1979, back in the Stone Ages. I can still remember my first UC Davis Dairy Cattle Day presentation (1980) in 194 Chemistry. I presented data from my Ph.D. research on forage quality at Penn State. In my research project the main forage was corn silage along with about three pounds of long alfalfa hay per cow daily. After my talk, a dairy producer came up to intr...

a number of 36 holstein young bulls (initial bw of 345±61 kg) were randomly assigned to 6 dietary treatments, following a 3 × 2 factorial arrangement, with three concentrate levels of fish oil (0, 1.5 and 3 % of dm) and 2 levels of alfalfa hay versus corn silage (10 and 20 % of alfalfa hay forage versus 20 and 10 % of corn silage) were used to investigate the effect of fish oil supplementation ...

The objectives of this study were to evaluate lauric acid (LA) as a practical ruminal protozoa-suppressing agent and assess effects of protozoal suppression on fermentation patterns and milk production in dairy cows. In a pilot study, 6 lactating Holstein cows fi tted with ruminal cannulae were used in a randomized complete-block design trial. Cows were fed a basal total mixed ration (TMR) cont...
