The aim of this study was to analyze the volatile compounds, physicochemical characteristics, and sensory properties Montasio, a semicooked pressed cheese, produced from milk dual-purpose Italian Simmental cows grazing on alpine pastures. A total 72 2 pastures, which differed in botanical composition (nutrient-rich pasture vs. nutrient-poor pasture), received different levels supplementation (3.0 vs 1.5 kg/head per day). experimental cheeses were whole, raw ripened for 60 d. Sixty-one...
Both condensed and hydrolysable tannins (CTs HTs, respectively) have the ability to reduce enteric CH 4 production in ruminants. However, precise mechanism of action is not fully understood. Among proposed hypotheses are reduction ruminal digestibility, direct control on protozoa, archaea, a hydrogen sink mechanism. In this vitro study, which simulated rumen fermentation, two additives, one containing CTs (70% based DM) from quebracho with HTs (75% chestnut, at four levels inclusion (2, 4,...
Residual feed intake (RFI), a widespread index used to measure animal efficiency, is influenced by various individual biological factors related inter-animal variation that need be assessed. Herein, 30 Simmental bulls, raised under the same farm conditions, were divided on basis of RFI values into high efficient group (HE, = −1.18 ± 0.33 kg DM/d, n 15) and low (LE, 0.92 0.35 15). Subsequently, bulls slaughtered at an average body weight 734 39.4 kg. Their ruminal fermentation traits analysed...
Rumen fermentation parameters and microbiota were evaluated in 3 vitro rumen experiments after addition of chestnut tannins (CWT) or an extract from Stevia rebaudiana Bertoni (SB) to substrates. A control (CTR) substrate was fermented alone added with 1.5% CWT SB extracts a batch culture system (Exp. 1, 500 mL for 24 h) subsequent continuous 2, 2 L bottles 9 d). Experiment used the Exp. 1 tested 7 doses each CTR (additions 0.2%, 0.4%, 0.6%, 0.8%, 1.0%, 1.2% 1.4% 48 h). The lowered (P < 0.01)...
The utilization of animal donors rumen fluid for laboratory experiments can raise ethical concerns, and alternatives to the collection fluids from live animals are urgently requested. aim this study was compare fresh (collected at slaughter, W) with that obtained a continuous fermenter (RCF) three methods preservation (refrigeration, R, chilling, C, freeze-drying, FD). fermentability different inoculum evaluated by in vitro tests (neutral detergent fiber (NDF) crude protein (CP)...
ABSTRACT Rumen degradability of dry matter (DM), organic (OM), nitrogen (N), neutral-detergent fibre (NDF), hemicellulose, cellulose and lignin was evaluated with the in situ technique for maize silage cocksfoot, timothy, fescue, lucerne meadow hays. The each six forages studied separately, forage being used turn as main component diet offered to four fistulated cows. For 300 g were mordanted sodium dichromate placed rumen when same studied. Faecal grab samples collected measure transit...
The aim was to evaluate 2 levels of dietary inclusion chopped whole-ear corn silage (WECS) on energy and nutrient utilization, growth, slaughter performances heavy pigs. Two in vivo experiments were conducted determine digestibility metabolic utilization WECS using 18 barrows weighing 118 ± 8 kg BW average, cages respiration chambers (Exp. 1), the effect growth performance carcass traits 42 from 90 170 2). In both experiments, pigs fed 3 experimental diets: a control diet (CON) containing...
Summary In three separate experiments, groups of four, and six mature, rumen-cannulated Simmental cows were fed diets designed to supply different quantities energy (E) nitrogen (N) the rumen microbes. Experiment 1 (straw plus concentrate urea) had balanced E N supplies; Expt 2 (hay four levels soyabean meal) sub-optimum at same intake as 1; 3 maize two reproduced shortage in a higher level intake. The amount total excreted urine (TUN) was 574 mg/kg LW 0·75 420 this purine (TPN). 2, TUN...
