Book excerpt: Eight Angus cross-bred cows (669 ± 23.2 kg of BW) fitted with duodenal and ruminal cannulas grazing winter wheat pasture (WWP) were used in a split-plot design to evaluate the effects of monensin supplementation and WWP stage of maturity on forage intake, digestive function, metabolizable protein, and ruminal fermentation. Supplemental treatment was the main plot, and stage of maturity was the subplot. Two levels of monensin supplementation: 1) Control (CON; 1.0 kgcow−1d−1 of wheat middling only), and 2) monensin (MON; CON plus 200 mg of monensin); and two stages of WWP maturity: 2) mid-March (MAR; March 13 to March 26; vegetative stage), and 2) early April) (APR; March 27 to April 8; heading stage) of 2017 were compared in a 2 x 2 factorial arrangement of treatments. Cows grazed in a single wheat pasture with supplements deposited directly into their rumens through their rumen cannula at 0700 daily. Monensin supplementation did not affect forage intake (P = 0.64), nutrient flow to duodenum (P ≥ 0.47) or total tract digestion expressed as kg/d (P > 0.45). Although, OM and CP flowing to the duodenum were not affected by monensin supplementation (P ≥ 0.53), microbial OM and microbial CP decreased (P = 0.03) with monensin supplementation. As stage of maturity of WWP advanced, forage intake (P = 0.02), ruminal digestibility of DM and OM (P ≤ 0.05) and total tract digestion expressed as kg/d (P = 0.01) decreased. Also, total duodenal CP (P = 0.01), microbial protein (P = 0.01), and feed protein (bypass protein; P = 0.03) flow decreased with advancing WWP stage of maturity. Monensin supplementation increased (P = 0.01) propionate (18.38, and 20.79 ± 0.55 mol/100 mol), and decreased (P = 0.01) the acetate: propionate ratio (3.26, and 2.73 ± 0.13). Ruminal pH (6.03 and 6.31 ± 0.08), acetate (54.6 and 58.3 ± 0.98 mol/100 mol), and acetate propionate ratio (2.52, and 3.48 ± 0.13) increased (P ≤ 0.04), and propionate (21.9, and 17.3 ± 0.56 mol/100 mol) decreased (P ≤ 0.05) with advancing WWP stage of maturity. Results suggest that monensin increases propionate without affecting forage intake, digestibility or metabolizable protein of cattle grazing WWP. Key words: metabolizable protein, microbial synthesis, monensin, winter wheat pasture

This book was released on 2017 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eight ruminally and duodenally cannulated, angus-crossbred cows (665 ± 20.6 kg) grazing winter wheat pasture (WWP) were used in a complete randomized design to evaluate the effects of fish meal (FM) supplementation on forage intake, characteristics of digestion and metabolizable protein of cattle grazing WWP. The experiment was conducted from March 7 through March 19, 2016. Treatments consisted of cows grazing in a single pasture and supplemented with FM to provide: control, no RUP supplement (CON), or FM supplemented at a level calculated to supply 10% of the forage CP intake as RUP (FM). Supplemental FM was placed directly into the rumen cannula once daily at 0700 h. Forage DM, NDF, CP, total OM intake, OM intake expressed as g/kg of BW were not affected (P ≥ 0.44) by FM supplementation. Also, supplemental FM had no effects on microbial protein efficiency (P = 0.34), microbial protein synthesis (P = 0.70), feed protein bypassing rumen fermentation (P = 0.72), or total CP flowing to duodenum (P = 0.07). Moreover, true ruminal, or total tract digestibility of OM, NDF, and CP were not affected (P ≥ 0.38) by FM supplementation. Ruminal pH (6.37, and 6.43 ± 0.09 for CON and FM, respectively), total VFA production (50.2, and 49.7 ± 0.1.74 mM for CON and FM, respectively), acetate (74.4, and 74.6 ± 0.77 mol/100 mol for CON and FM, respectively), propionate (16.7, and 16.1 ± 0.62 mol/100 mol for CON and FM, respectively) and acetate/propionate ratio (4.49 and 4.69 ± 0.22 for CON and FM, respectively) were not affected by FM supplementation (P ≥ 0.49). Although FM supplementation did not decrease forage intake, it failed to improve MP of cows grazing WWP. The results indicate that improvements in performance of cattle grazing WWP should not be expected with supplementing FM at the level supplemented in this experiment

This book was released on 2014 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eight ruminally and duodenally cannulated, Angus-crossbred heifers (272 ± 19.2 kg) grazing winter wheat pasture (WWP) were used in a completely randomized design to evaluate effects of wheat middling (WM; offered at 0.4% of BW; as-fed basis) supplementation on metabolizable protein. The experiment was conducted from April 5 through April 19, 2013. Heifers grazed in a single WWP with supplements offered individually, once daily at 0700 h. Forage DM, total OM, NDF intake, and OM intake expressed as g/kg of BW were not affected (P [greater than or equal to] 0.11) by WM supplementation, and total CP intake (P = 0.03) increased with WM supplementation. Supplementation of WM increased the flow of OM, and CP (P [less than or equal to] 0.04) to the small intestine, but not the flow of NDF (P = 0.40). Feed protein flowing to the small intestine was not affected (P = 0.26) and microbial protein tended to increase (P = 0.10) with WM supplementation. Total tract OM, CP, and NDF digestibility were not affected (P [greater than or equal to] 0.13) by WM supplementation. Ruminal pH decreased and total VFA production increased (P = 0.01) with WM supplementation. Ruminal ammonia (P = 0.65), molar proportion of VFA (P [greater than or equal to] 0.11), and acetate to propionate ratio were not affected (P - 0.25) by WM supplementation. Supplementation of WM to cattle grazing WWP improves metabolizable protein by increasing microbial protein synthesis.

Available in PDF, EPUB and Kindle. Book excerpt: The ruminant animal is unique in that it can convert large quantities of cellusose into high quality human food. This is possible due to the large population of microorganisms in the rumen. Because of this capability, ruminants will occupy an even more important role in world food prodution in the future., especially in areas where land is not suitable for crop production. However, the need for increased animal efficiency and /or performance is becoming more critical as the food supply becomes more limited, and as the demand for grain and other plant products for human comsumption increases. Monensin, a biologically active compound produced by Streptomyces cinnamonensis has been shown to improve feed efficiency when added to high concentrate feedlot rations. Monensin-fed feedlot cattle tend to conume less feed but gain at a similar rate as non-monensin fed cattle. When fed to cattle grazing green forage, monensin has increased both gain and efficiency. Since forage is the principle fedd source for the beef cow, any compound which could alter efficiency and /or performance of grazing cows could affect the profitability of the beef cow enterprise. Information is not available, however, on the effectivevess of monensin when fed to range beef cows grazing low quality range grass. The purposes of this study were: 1) to evaluate the effect of monensin on milk production and milk composition for lactating range cows; 2) to evaluate the effect of monensin on forage and supplement intake and 3) to estimate the effect of monensin on rumen turnover rates and rumen components.

Available in PDF, EPUB and Kindle. Book excerpt: In a changing climate, livestock production is expected to exhibit dual roles of mitigation and adaptation in order to meet the challenge of food security. This book approaches the issues of livestock production and climate change through three sections: I. Livestock production, II. Climate change and, III. Enteric methane amelioration. Section I addresses issues of feed quality and availability, abiotic stress (heat and nutritional) and strategies for alleviation, livestock generated nitrogen and phosphorus pollution, and approaches for harnessing the complex gut microbial diversity. Section II discusses the effects of climate change on livestock diversity, farm animal reproduction, impact of meat production on climate change, and emphasising the role of indigenous livestock in climatic change to sustain production. Section III deals with the most recent approaches to amelioration of livestock methane such as breeding for low methane emissions, reductive acetogenesis, immunization/vaccine-based concepts and archaea phage therapy.
