Thirty-six multiparous dairy @entity291 (8 fitted with ruminal cannulas) and 16 primiparous dairy @entity291 were blocked by days in milk and parity and assigned to one of four diets containing 53% alfalfa silage [ @entity62 ( @entity62 ) basis] plus 1) high moisture ear @entity4336 , 2) high moisture ear @entity4336 plus expeller @entity1460 meal, 3) ground high moisture ear @entity4336 , or 4) ground high moisture ear @entity4336 plus expeller @entity1460 meal. The high moisture ear @entity4336 was rolled before ensiling at 68% @entity62 . Ground high moisture ear @entity4336 was prepared by further grinding through a 9.5-mm screen; grinding reduced the geometric mean particle size from 4.33 to 1.66 mm. Diets contained 1.69 Mcal of net energy for lactation/kg of @entity62 . Relative to @entity291 fed diet 1, milk yield was 4 kg/d greater for @entity291 fed diet 2; numerically, milk yield was about 2 kg/d greater for @entity291 fed diets 3 and 4 than for @entity291 fed diet 1. Yield of milk components also was greater for @entity291 fed diets 2 and 3 but not for @entity291 fed diet 4. Intake of @entity62 and yield of 4% FCM were greatest for @entity291 fed diet 3 and lowest for @entity291 fed diet 1. Digestibilities of @entity62 , organic matter, starch, neutral detergent fiber, and acid detergent fiber were increased, and ruminal @entity3655 concentration was depressed, by the grinding of high moisture @entity4336 ; expeller @entity1460 meal increased ruminal @entity3655 . Total volatile @entity844 concentration was not different among in vivo treatments, but the molar proportion of @entity598 decreased, and @entity4919 increased, for @entity291 fed diet 3. The grinding of high moisture @entity4336 significantly decreased pH, increased total volatile @entity844 concentration, and increased the rate of decline of @entity3655 concentration in ruminal in vitro incubations. Grinding improved the utilization of high moisture @entity4336 by lactating @entity291 by stimulating ruminal fermentation.

Effect of processing high moisture ear XXXX on ruminal fermentation and milk yield.
