Dissolved hydrogen (dH2) influences the pathways of VFA production and is a precursor methane formation in rumen. Measurements dH2 rumen fluid taken at same time as measuring other fermentation end products would improve our quantitative understanding role controller fermentation. Sample collections though cannula using oral stomach tubing were compared for measurements dissolved gases 4 ruminally cannulated dairy cows fed total mixed ration corn silage concentrate. Rumen was collected 0,...
The objectives of this study were to examine long-term effects feeding forage rape (Brassica napus L.) on methane yields (g per kg feed dry matter intake), and propose mechanisms that may be responsible for lower emissions from lambs fed compared perennial ryegrass (Lolium perenne L.). fresh winter or as their sole diet 15 weeks. Methane measured using open circuit respiration chambers, 22-30% smaller than (averages 13.6 g versus 19.5 after 7 weeks, 17.8 22.9 weeks). difference therefore...
Abstract The aim of this study was to evaluate the effect two commercial enzyme products on milk production in Egyptian buffaloes. Twenty-one lactating buffaloes (570±15 kg BW) were divided into three groups (n=7) a randomized block design for four months. Buffaloes fed total mixed ration containing 60% forage [rice straw and berseem hay (Trifolium alexandrinum)] 40% concentrates with either no enzymes added (Control) or an addition 40 g Veta-Zyme Plus ® (VET) Tomoko (TOM ) product per day...
Butyrate promotes the growth and gastrointestinal development of calves. But, mechanisms behind its effects on signaling pathways tract rumen microbiome is unclear. This study aimed to reveal transcriptomic epithelium microbial community in response butyrate supplementation calves fed a high fiber starter. Fourteen Holstein bull (39.9 ± 3.7 kg, 14 d age) were assigned 2 groups (sodium group, SB; control Ctrl). The SB group received 0.5% supplementation. At 51, slaughtered obtain samples for...
Feeding pelleted total mixed rations (TMR) instead of traditional loose concentrate plus forage to fattening lambs is an emerging practice. This study aimed determine the effects feeding TMR on feed intake behaviour, growth performance, digestion, rumen fermentation characteristics, microbial community, serum parameters, slaughter meat quality, and economic outcome. Two physical forms (pelleted vs. un-pelleted) composed same ingredients with particle sizes were compared in three animal...
Water-soluble components of feedstuffs are mainly utilized during the early phase microbial fermentation, which could be deemed an important determinant gas production behavior in vitro. Many studies proposed that fractional rate degradation (FRD) estimated by fitting curves to mathematical models might used characterize incubation for vitro systems. In this study, concept FRD was developed on basis Logistic-Exponential (LE) model, with initial volume being zero (LE0). The LE0 model exhibits...
In New Zealand, agriculture is predominantly based on pastoral grazing systems and animal excreta deposited soil during have been identified as a major source of nitrous oxide (N2O) emissions. Forage brassicas (Brassica spp.) increasingly used to improve lamb performance. Compared with conventional forage perennial ryegrass (Lolium perenne L.), common in faster growth rates, higher dry matter production nutritive value. The aim this study was determine the partitioning dietary nitrogen (N)...
A series of experiments was conducted in New Zealand to evaluate the potential forage brassicas for mitigation enteric methane emissions. Experiments involved sheep and cattle fed winter summer varieties brassica crops. In sheep-feeding trials, it demonstrated that several species can result, a varying degree, lower yield (g per kg DM intake) than does ryegrass pasture. Pure rape as crop resulted 37% yields did Increasing proportion diet pasture linearly decreased yield. Feeding also 44%...
Dietary nutrient manipulation (e.g. protein fractions) could lower the environmental footprints of ruminants, especially reactive nitrogen (N). This study investigated impacts dietary soluble (SP) levels with decreased crude (CP) on intestinal N absorption, hindgut metabolism, fecal microbiota and metabolites, their linkage metabolism phenotype. Thirty-two male Hu sheep, an age six months initial BW 40.37 ± 1.18 kg, were randomly assigned to four groups. The control diet (CON), aligning NRC...
The aim of the present study was to investigate dietary effects replacing corn with different proportions fermented straw on growth performance and intestinal health finishing pigs. A total 275 healthy commercial pigs aged 126 days (average body weight, 82.96 ± 3.07 kg) were randomly allocated into three groups: control (CTR, basal diet) group, 5% (FJJG5, corn) 10% (FJJG10, group. There six replicates in each group 14–16 per replicate. On day 39 experiment, one animal from replicate...
Both corn gluten feed and bakery by-products are important alternative concentrate feedstuffs for ruminants. Bakery by-products, which rich in ether extract (EE) starch, have the potential to be utilized as ruminants, with a capacity reduce ruminal methanogenesis. In study, fermented (FCG) (FBP) were mixed other formulate FCG FBP diets, respectively. Twenty growing Holstein bulls, weighing 241 ± 10.5 kg, randomly assigned one of two dietary treatments: or diet. The aim was investigate...
Five experiments were conducted to examine effects of lysophospholipids (LPL) on live weight gain, nutrient digestibility, ruminal fermentation parameters, serum biochemical parameters and rumen bacterial community profile in fattening lambs. Two dietary treatments (pelleted complete feed supplemented without (control diet; CON) or with 0.05% LPL dry matter basis) tested these experiments. Feed water provided ad libitum The results showed that average daily gain (ADG) tended increase was not...
