Impact of ruminal pH on enteric methane emissions

Autor: M, Hünerberg, S M, McGinn, K A, Beauchemin, T, Entz, E K, Okine, O M, Harstad, T A, McAllister

Publikováno v: Journal of animal science. 93(4)

The objective of this study was to determine the impact of ruminal pH on methane (CH4) emission from beef cattle. Ruminal pH and CH4 data were generated in 2 experiments using 16 beef heifers offered high-forage (55% barley silage) or high-grain (92%

Enteric methane emission, diet digestibility, and nitrogen excretion from beef heifers fed sainfoin or alfalfa

Autor: Y-H, Chung, E J, Mc Geough, S, Acharya, T A, McAllister, S M, McGinn, O M, Harstad, K A, Beauchemin

Publikováno v: Journal of animal science. 91(10)

Effects of plant-bound condensed tannin (CT)-containing sainfoin vs. CT-free alfalfa (or low-CT alfalfa-sainfoin mixture), plant stage of maturity, and their interaction on enteric methane (CH4) emissions, diet digestibility, and N excretion were stu

Effect of dried distillers grains plus solubles on enteric methane emissions and nitrogen excretion from growing beef cattle

Autor: M, Hünerberg, S M, McGinn, K A, Beauchemin, E K, Okine, O M, Harstad, T A, McAllister

Publikováno v: Journal of animal science. 91(6)

The objectives of this study were to examine the impact of corn- or wheat-based dried distillers grains with solubles (CDDGS or WDDGS) on enteric methane (CH4) emissions from growing beef cattle and determine if the oil in CDDGS was responsible for a

Effects of increasing concentrations of glycerol in concentrate diets on nutrient digestibility, methane emissions, growth, fatty acid profiles, and carcass traits of lambs

Autor: J, Avila-Stagno, A V, Chaves, M L, He, O M, Harstad, K A, Beauchemin, S M, McGinn, T A, McAllister

Publikováno v: Journal of animal science. 91(2)

Two experiments were conducted to evaluate the effects of increasing concentrations of glycerol in concentrate diets on total tract digestibility, methane (CH4) emissions, growth, fatty acid profiles, and carcass traits of lambs. In both experiments,

The effect of excess cobalt on milk fatty acid profiles and transcriptional regulation of SCD, FASN, DGAT1 and DGAT2 in the mammary gland of lactating dairy cows

Autor: I J, Karlengen, O M, Harstad, O, Taugbøl, I, Berget, A H, Aastveit, D I, Våge

Publikováno v: Journal of animal physiology and animal nutrition. 96(6)

The main objective of this study was to investigate the effect of excess cobalt (Co) on gene expression of stearoyl-CoA desaturase (SCD), fatty acid synthase (FASN), diacylglycerol acyltransferase 1 (DGAT1) and diacylglycerol acyltransferase 2 (DGAT2

Cobalt reduces the Δ⁹-desaturase index of sow milk

Autor: I J, Karlengen, O M, Harstad, N P, Kjos, B, Salbu, A H, Aastveit, O, Taugbøl

Publikováno v: Journal of animal physiology and animal nutrition. 95(5)

The main objective of this study was to examine if cobalt (Co) reduces Δ(9) -desaturase indices in milk and blood lipids in sows. The experimental design consisted of a repeated measurement consisting of a pre-treatment period of a minimum of 9 days

Intravenous injections of cobalt reduce fatty acid desaturation products in milk and blood of lactating cows

Autor: O, Taugbøl, I J, Karlengen, B, Salbu, A H, Aastveit, O M, Harstad

Publikováno v: Journal of animal physiology and animal nutrition. 94(5)

The objective of this study was to determine whether intravenous infusion of Co affects levels of fatty acid desaturation products in bovine milk. Six cows were assigned to two replicated 3 × 3 Latin squares with 14-day periods. Treatment occurred o

Cobalt supplied per os reduces the mammary Delta9-desaturase index of bovine milk

Autor: O, Taugbøl, I J, Karlengen, T, Bolstad, A H, Aastveit, O M, Harstad

Publikováno v: Journal of animal science. 86(11)

Results indicated that the dual marker system of Yb-acetate and Co-EDTA supplied per os reduced the proportion of fatty acids in bovine milk that were products of Delta (9)-desaturase. To verify this effect and identify the responsible marker compone
