Effects of homo-fermentative bacterial inoculants on fermentation characteristics and nutritive value of low dry matter corn silage
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...
متن کاملthe effects of high non fibrous carbohydrates diet on milk production, inflammation and molecular mechanism of innate immunity in lactating dairy cows
پژوهش حاضر با هدف بررسی اثر جیره حاوی کربوهیدراتهای غیرالیافی زیاد و بروز التهاب در گاوهای شیرده در دو آزمایش جداگانه انجام شد. در آزمایش اول 20 رأس گاو مبتلا به ورم پستان از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) و 20 رأس گاو سالم از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) انتخاب شدند. همه گاوها در دوره دوم و یا سوم شیردهی و در روزهای 80-120 پس از زایش بودند. میانگین تولید شیر در گروه...
Corn silage versus corn silage:alfalfa hay mixtures for dairy cows: effects of dietary potassium, calcium, and cation-anion difference.
Corn silage (CS) has replaced alfalfa hay (AH) and haylage as the major forage fed to lactating dairy cows, yet many dairy producers believe that inclusion of small amounts of alfalfa hay or haylage improves feed intake and milk production. Alfalfa contains greater concentrations of K and Ca than corn silage and has an inherently higher dietary cation-anion difference (DCAD). Supplemental dieta...
متن کاملInfluence of corn silage particle length on the performance of lactating dairy cows fed supplemental tallow.
The objective of this study was to determine if the length of chop of processed corn silage influences the impact of supplemental fat on rumen fermentation and performance of dairy cows. We hypothesized that increasing forage particle length may alleviate the interference of fat on rumen fermentation. Sixteen Holstein cows averaging 120 d in milk were used in a replicated 4 x 4 Latin square des...
متن کاملNutriDense corn grain and corn silage for dairy cows.
Twenty multiparous Holstein cows, 4 of them surgically fitted with ruminal cannulas, were used in a replicated 4 x 4 Latin square to compare the effects of whole-plant silage and grain produced from NutriDense (ND), leafy NutriDense (LND), or a conventional yellow dent (YD) hybrid on ruminal fermentation, total tract nutrient digestibility, and performance of lactating dairy cows. On a DM basis...
