The objectives of this study were to determine the effect of fresh pasture forage quality (vegetative and mature pasture in different seasons), feeding level and supplementation with maize silage or palm kernel expeller on methane (CH4) production (g/day) and yield (g/kg dry matter intake; DMI) in growing beef cattle. The null hypothesis was that pasture quality, DMI level and supplementation have no effect on the CH4 yield (g/kg DM) in beef cattle. Four experiments were conducted and in three experiments (Exp. 1–3) freshly cut vegetative or mature pasture was fed to 14 growing beef animals in two consecutive periods, respectively, at intake levels of 1.5, 1.8 and 1.1 × maintenance metabolisable energy requirements (MEm) in Exp. 1–3, respectively. For Exp. 3, 100% maize silage was fed in a third consecutive period to the same cattle used in Periods 1 and 2. In Exp. 4, 4 animals were fed one of three treatments at 1.6 × MEm of 100% fresh pasture, fresh pasture supplemented with 35% DM maize silage or fresh pasture supplemented with 35% DM palm kernel expeller. After acclimatisation to respective diets, DMI and CH4 were measured for 12 animals in individual open circuit respiration chambers for two consecutive days in each experiment. Methane yield (g/kg DMI) was similar when animals were fed vegetative or mature pasture in Exp. 1 (20.0) and 2 (25.8), whereas in Exp. 3 feeding vegetative pasture resulted in a higher CH4 yield (25.7; P < 0.05) compared with feeding mature pasture (23.3), with feeding 100% maize silage intermediate (23.8). Methane yield of cattle fed pasture supplemented with maize silage in Exp. 4 was 10% higher (P < 0.05) compared with cattle fed mature pasture only or supplemented with palm kernel expeller (25.9, 23.3, 23.4 g/kg DMI, respectively). The regression between DMI and CH4 yield was similar for vegetative and mature pasture and pasture composition could explain up to 26% of variation in CH4 yield (P < 0.05). The CH4 yield in cattle fed 100% pasture (Exp. 1–3) was not affected by DMI and averaged 24.1 ± 2.78 g/kg DMI. In conclusion, fresh pasture forage quality, feeding level and supplementation had only minor, but some significant, effects on CH4 yield in beef cattle.

Dry matter (DM) concentration of maize silage is directly related to maturity of the crop at harvest and widely reported to be positively correlated with total forage DM intake. The objective of this experiment was to investigate these effects using a late maturing beef genotype and a contemporary forage maize variety.Forage maize (variety Hudson) was harvested at four different stages of maturity during September and October 1996. Each stage of maturity was ensiled in a separate clamp with no additive. Resultant silage corrected dry matter contents were 247 (L), 305 (M/L), 331(M/H) and 388 (H)g/kgFW, respectively. Each diet was formulated to be isonitrogenous with fishmeal fed twice daily on top of the silage. Silage was offered ad libitum to 32 growing Simmental X Friesian heifers (mean initial weight 217kg), housed in individual pens in an open-sided Dutch barn and bedded on wheat straw. Eight animals were allocated to each treatment, in a completely randomised design with pre-treatment intake (non-experimental maize silage) used as a covariate in the statistical analysis.

Abstract: Enteric methane (CH4) production is the main source of greenhouse gas emissions from livestock globally with beef cattle contributing 5.95% of total global greenhouse gas emissions. Various mitigation strategies have been developed to reduce enteric emissions with limited success. In vitro studies have shown a reduction in CH4 emissions when using garlic and citrus extracts. However, there is paucity of data regarding in vivo studies investigating the effect of garlic and citrus extracts in cattle. The objective of this study was to quantitatively evaluate the response of Angus × Hereford cross steers consuming the feed additive Mootral, which contains extracts of both garlic and citrus, on CH4 yield (g/kg dry matter intake [DMI]). Twenty steers were randomly assigned to two treatments: control (no additive) and Mootral supplied at 15 g/d in a completely randomized design with a 2-wk covariate and a 12-wk data collection periods. Enteric CH4 emissions were measured using the GreenFeed system during the covariate period and experimental weeks 2, 6, 9, and 12. CH4 yield (g/kg DMI) by steers remained similar in both treatments for weeks 2 to 9. In week 12, there was a significant decrease in CH4 yield (23.2%) in treatment compared to control steers mainly because the steers were consuming all the pellets containing the additive. However, overall CH4 yield (g/kg DMI) during the entire experimental period was not significantly different. Carbon dioxide yield (g/kg DMI) and oxygen consumption (g/kg DMI) did not differ between treatments during the entire experimental period. DMI, average daily gain, and feed efficiency also remained similar in control and supplemented steers. The in vivo results showed that Mootral may have a potential to be used as a feed additive to reduce enteric CH4 production and yield in beef cattle but needs further investigation under various dietary regimen.

Abstract Crossbreeding has been used to improve performance in beef cattle; however, the effects of breed composition on methane production, yield and intensity from cattle in a tropical intensive system remain unknown. To assess the impact of breed composition on enteric methane emissions, Nellore (NE; yr 1: BW = 171.5 ± 19.4 kg; n = 10; yr 2: BW = 215.8 ± 32.3 kg, n = 25) and Angus-Nellore crossbred (AN; yr 1: BW = 214.2 ± 26.4 kg, n = 10; yr 2: BW = 242.5 ± 32.2 kg, n = 25) were compared. At trial onset, 10 mo old steers grazed Megathyrsus maximus ‘Mombaça’ in the grazing period (GP) and then were finished in a feedlot (FL) (35:65% corn silage:concentrate diet). Steers (n = 8) from each breed composition were randomly selected in GP and FL to measure CH4 production using a sulfur hexafluoride technique and DMI using titanium dioxide. The NE produced 19% less CH4 than AN in GP (17.21 vs 21.17 kg, P &lt; 0.01), and no difference was observed in FL (22.34 vs 22.67 kg, P &gt; 0.10). However, in FL, NE had greater CH4 intensity (CH4/ADG) compared to AN (122.76 vs 97.49 g/kg, P &lt; 0.01). Furthermore, CH4/carcass weight was greater for NE than AN (0.079 vs 0.067 g/kg CW, P &lt; 0.01). Breed composition did not influence CH4 yield (CH4/DMI) in either phase. The percentage CH4/GEI (Ym) for GP was higher for AN than NE (4.5 vs 3.8%), but lower than the IPCC recommended Ym of 6.5%. In FL, Ym was similar between breed composition (5.0%) and greater than the IPCC Ym of 3%. In our study the introduction of Angus into Nellore has potential to reduce CH4 intensity in tropical climates, resulting in less methane emission per kg beef produced.

Analysis Of Results

This paper provides the analysis of results of biogas and methane yield for: maize silage (MS), pig slurry (PS), waste potatoes (WP) and sugar beet pulp (SB). The results show that maize silage is the most energy substrate (among the samples tested), providing a cumulative methane yield from 595 to 631 m-3 Mg VS (VS – volatile solids). The study was carried out in a laboratory scale using anaerobic batch reactors, at controlled (mesophilic) temperature and pH conditions. This paper is Part I of a report of an experiment carried out, in the laboratory scale and in the commercial scale (in parallel) The purpose of the experiment was to verify differences in biomethane yields of the same materials in the two scales. Moreover, this paper is an introduction to a presentation of the method to determine the biochemical methane potential correction coefficient (BMPCC), the details of which will be explained in Part II.

The disappearance of total N, non-protein-N and amino acid-N after washing, rumen incubation and intestinal passage of sugarbeet pulp, maize-gluten feed, maize feed meal, palm kernel meal, soyabean hulls, soyabean meal, grass silage, maize silage and concentrate was measured in four dairy cows using nylon-bag techniques. Disappearance of amino acid-N after washing varied between feedstuff's from 14 to 69% of feed amino acid-N, and was lower than disappearance of non-protein-N. For sugarbeet pulp, grass silage and maize silage, washing had a considerable effect on the amino acid profile. Disappearance of amino acid-N after rumen incubation was also lower than non-protein-N and varied between feedstuffs from 25 to 73% of feed amino acid-N. Rumen incubation had only a small effect on the amino acid profile of the residue after washing. Disappearance of amino acid-N in the intestine varied between feedstuffs from 70 to 99% of rumen undegraded amino acid-N, and was higher than the disappearance of non-protein-N. Intestinal incubation showed a considerable effect on the amino acid profile for all feedstuffs. It was concluded that protein that was assumed to escape rumen degradation and was absorbable in the intestine was higher in amino acids and methionine, and lower in non-amino acid-N and glutamic acid and proline compared with protein in the feedstuff.
