We evaluated the effect of feed additives on the risk of ruminal acidosis in Holstein heifers (n = 40) fed starch and fructose in a challenge study. Heifers were randomly allocated to feed additive groups (n = 8 heifers/group): (1) control (no additives); (2) virginiamycin (VM); (3) monensin + tylosin (MT); (4) monensin + live yeast (MLY); and (5) sodium bicarbonate + magnesium oxide (BUF). Hei...

The present study was conducted to evaluate whether bodyweight and the micronisation of dietary fibre affect the endogenous nitrogen and amino acid losses (ENL and EAAL) in pigs. The effect of the micronising process was tested by providing pigs with 90 g DM x kg(-1) BW0.75 of a N-free diet supplemented with isolated pea inner fibres, presented in native or micronised form and with a water-hold...

The objective of this research was to evaluate the effects of residual feed intake (RFI) determined under ad libitum feeding conditions on DMI and performance of yearling ewes fed either chopped or pelleted alfalfa hay. In Exp. 1, 45 ewe-lambs had ad libitum access to a pelleted grower diet for 63 d and individual DMI was determined using an electronic feed delivery system. Residual feed intake...

Patients 1000 women between 16 and 45 years of age seeking emergency contraception within 72 hours after an episode of unprotected sexual intercourse who had regular menstrual cycles (21–35 d), were certain about the dates of their last menstrual period, and were willing to abstain from further acts of unprotected intercourse during the menstrual cycle. Exclusion criteria were use of oral contr...

Abstract The aim of this study was to evaluate the effects on dry matter intake (DMI), daily gain (DG), feed efficiency (FE) and rumen fermentation including fresh alfalfa (FA) a restricted TMR diet finishing steers. Twenty steers (8 with 8-mm ruminal catheters), fed (ground corn grain, soybean meal, pasture hay, mineral-vitamin concentrate Anavrin; 65% DM, 12.8% CP, 23% NDF) were blocked by BW...

1Department of Animal Sciences, NDSU The objectives of this study were to determine the effects of forage inclusion level on growth performance, feeding behavior and carcass characteristics in finishing steers. These results indicate that a decrease in forage inclusion from 20 to 5 percent (dry-matter [DM] basis) in a finishing diet increases dry-matter intake (DMI), average daily gain (ADG) an...

Abstract There is a need to understand the feeding behavior ontogeny of newly received high-risk steers. Understanding how calves learn eat out bunk will facilitate implementation management practices that expedite this process and allow animal managers exploit information monitor individual health. To address knowledge gap, steers were for backgrounding was quantified characterized using elect...

The objective of this experiment was to determine the association of glucocorticoids and markers for immune status in finishing beef steers and heifers with DMI, growth, and efficiency. Steers ( = 127) and heifers ( = 109) were individually fed a finishing ration for 84 d with BW measured every 21 d. Blood samples were collected via jugular venipuncture for metabolite (glucose and lactate) and ...
