This experiment was performed to investigate whether feeding xylose-treated soybean meal (XSBM) or corn gluten meal (CGM) is economically better under field conditions. Ninety-four multiparous early lactating Holstein cows (55±5 days in milk and 2.82±0.41 body condition score) were used in a completely randomized design. Cows were randomly assigned to one of two treatments: XSBM or CGM as the m...

a digestion trial using cannulated lactating cows was conducted to evaluate the influence of barley grain processing on characteristics of ruminal fermentation and the site and extent of digestion. the experiment consisted in 4 periods and lasted 84 days. the total mixed rations contained 39.86% of grains and 42.90% of alfalfa hay and the rest of ration was composed mainly by cane molasses, fat...

The objectives were to compare milk production and composition, change in body weight and body condition score, rumen fermentation parameters and grazing patterns by cows when supplemented with different forms and amounts of corn grain. In experiment 1, 36 Holstein cows were supplemented with either 6, 6, 6, or 4 kg/d of dry matter of high moisture corn, coarsely ground corn, finely ground corn...

the aim of this study was to investigate the effect of feeding of  steeped barley grain with lactic acid (la) and citric acid (ca) on dry matter intake, feeding behavior, apparent nutrients digestibility, rumen ph and milk production. eight early lactating holstein cows in the second parities were used in 4×4 latin square change- over design. treatments  consisted of basis diet containing 1) dr...

The objectives of this study were to determine how feeding diets that differed in dietary neutral detergent fiber (NDF) concentration and in vitro NDF digestibility affects dry matter (DM) intake, ruminal fermentation, and milk production in early lactation dairy cows. Twelve rumen-cannulated, multiparous Holstein cows averaging 38 +/- 15 d (+/-standard deviation) in milk, and producing 40 +/- ...

in the past decade, a global demand for products from organic agriculture has increased rapidly. milk quality is of major interest for all parties. therefore, the objective of this study was to compare cow performance and product quality in conventional and organic system. twenty holstein dairy cows were allotted to one of 2 diet groups, which including: a conventional diet (con), and an organi...

the effect of different levels of alfalfa hay and corn silage, in early lactation diet, on milk production and on milk components in holstein cows was investigated. fifteen holstein cows (37 ±10 dim) were taken in a completely randomized design experiment, lasting for 9 weeks. three levels of hay and corn silage namely: 1) 10% alfalfa -30% silage corn (diet 1), 2) 20% alfalfa -20% silage corn (...

Eight ruminally cannulated multiparous Holstein cows that were part of a larger production trial were used to study the effects of varying dietary ratios of alfalfa silage (AS) to corn silage (CS) on omasal flow of nutrients and microbial protein. Cows were blocked by DIM and randomly assigned to 2 replicated 4 x 4 Latin squares (28-d periods). Diets fed contained (dry matter basis): A) 51% AS,...
