This study tested whether the effects of a short period nutritional supplementation given to ewes during luteal phase on follicle development and ovulation rate is associated with an increase in circulating concentrations FSH, glucose or metabolic hormones. Oestrus was synchronised two prostaglandin injections 9 days apart supplement consisted corn grain soybean meal. Corriedale low body condition were randomly assigned 2 groups: control group (C; n = 10) received maintenance diet while...
This study investigated the effects of adding a blend essential oils, tannins, bioflavonoids (ANAVRIN®, VetosEurope, Lugano, Swuitzerland), monensin, and their combination on performance rumen fermentation finishing steers fed total mixed ration (TMR). Thirty (441 kg body weight, 34.3 months old) consuming TMR were blocked by BW randomly assigned to three treatments according addition of: 1) EOTB (ANAVRIN® at 0.35 g/100 weight); 2) MON (monensin 0.033 g/kg dry matter); 3)...
This study investigated the effects of adding a blend essential oils, tannins, bioflavonoids (ANAVRIN®, VetosEurope, Lugano, Switzerland), monensin, and their combination on daily gain, feed conversion, rumen fermentation finishing steers fed total mixed ration (TMR). Thirty (441 kg body weight, 34.3 months old) consuming TMR were blocked by BW randomly assigned to three treatments according addition (1) EOTB (ANAVRIN® at 0.35 g/100 weight), (2) MON (monensin 0.033 g/kg dry matter), (3) +...
Enteric methane (CH4) emissions are directly related to the quantity and type of feed intake. Existing mitigation strategies, for example, addition legumes grass-based diets increased use grains, have been thoroughly researched applied in different production systems. In this paper, we propose a need expand capacity mitigate enteric CH4 cattle under grazing conditions. The objective paper was contribute evaluate strategy conditions using contrasting levels pasture quality. study performed...
The aim of the experiment was to study diurnal variation in water-soluble carbohydrate (WSC) concentrations leaf and stem tall fescue lucerne autumn determine impact these changes on rate extent vitro fermentation. Vegetative herbage were sampled at 0900, 1300 1700 h, following three consecutive regrowths between April May. Whole plants, analysed for chemical composition gas production. There a linear increase WSC throughout day all plants plant components (P < 0.001). In both lucerne, this...
Our aim was to evaluate whether increasing soluble carbohydrates in the herbage by changing time of grazing session or including Acacia mearnsii tannin diet would affect intake, digestion, N partitioning, and productive performance dairy cows fed a combining ryegrass with partial total mixed ration (PMR). We hypothesized that both strategies could reduce concentration NH3-N rumen, reducing urinary excretion. Nine Holstein were used triplicate 3 × Latin square experiment experimental periods...
Fermentation kinetics, digestibility, faecal characteristics and bacterial populations (aerobes, anaerobes, lactobacilli, lactic acid bacteria, enterococci, coliforms clostridia) of dog food mixed with citrus pulp apple pomace were evaluated. The in vitro gas production a pre-digested 0, 30, 50 70 g/kg dry matter (DM) or was measured, also an experiment dogs fed the same without addition either fresh conducted. Gas increased linearly (p < 0.001) quadratically as fibre levels augmented....
The objective of this study was to quantify the emissions enteric CH4 from growing Hereford steers raised under feedlot conditions based on contrasting levels residual feed intake (RFI). A repeated measurements experiment conducted over 20 d determine production two groups nine steers, with RFI values (mean ± SD): low (LRFI group; -0.78 0.22 kg DMI/d) vs. high (HRFI 0.83 0.34 DMI/d). Steers were selected a larger contemporary population in which evaluated. maintained confined ad libitum...
The aim of this study was to assess the potential consequences on calf intake, performance, behavior, ruminal microbiome, and epithelium development combining inclusion chopped barley straw alfalfa hay during pre- post-weaning periods keeping concentrate forage ratio constant among dietary treatments. Forty-five Holstein calves (44 ± 5.7 kg BW 3 1.5 d age) individually penned were blocked by body weight (BW) randomly assigned a common pellet fed ad libitum along with one following feeding...
To determine whether non-fibrous carbohydrate (NFC) supplementation improves fiber digestibility and microbial protein synthesis, 18 Corriedale ewes with a fixed intake level (40 g dry matter (DM)/kg BW0.75) were assigned to three (n = 6) diets: F 100% fresh temperate forage, FG 70% forage + 30% barley grain FGM 15% molasses-based product (MBP, Kalori 3000). Two experimental periods carried out, late (P1) early (P2) vegetative stage forage. For P2, fitted ruminal catheters. Forage was...
Diets combining herbage and total mixed rations (TMR) are increasingly used in temperate regions for feeding ruminants, but little information is available regarding the effects on nutrient intake digestion of this management beef cattle. The aim study was to determine TMR (10% CP 13% ADF), legume-based (14% 27% ADF) intake, digestion, ruminal fermentation, microbial N flow glucose nitrogen metabolism heifers. experiment a 3×3 Latin square design replicated three times; each period lasted 18...
The nutritive value of cardoon (Cynara cardunculu.sL.) green forage (GF), dry leaves (DL) and straw (S) was studied from chemical composition analyses voluntary intake, digestibility rumen degradability estimations obtained using adult wethers.Aptitude for being ensiled according to the wilting period also evaluated making silages with fresh after 24 94 hours wilting.Green had a high value, as shown by low levels fibre lignin its very (86 % OM).Nevertheless, intake rel- atively (64 g DM.kg!'...
The present study was conducted to determine the effect of feed intake on composition rumen contents sheep and their bacterial densities.
