“…Similar responses in DMI to tannin supplementation of higher forage diets have been also reported in feeding trials involving goats (Puchala et al 2005), lambs (Douglas et al 1995), and in cows (Woodward et al 2000). In contrast, Krueger et al (2010) and Mezzomo et al (2011) did not observe effects of supplemental tannins (1.5% and 0.4% of diet, respectively) on DMI of finishing feedlot steers. High levels of dietary tannin (> 5% tannins of diet) have markedly depressed feed intake in ruminants (Frutos et al 2004).…”

Two trials were conducted to evaluate the effect of tannin supplementation of steers during the feedlot finishing phase. In Trial 1, 96 Holstein steers (478 ± 6.5 kg) were used to evaluate the effects of level of supplemental condensed tannin (0%, 0.2%, 0.4%, and 0.6% of dry matter basis) on growth performance. Supplemental tannin increased (6.5%, P = 0.05) weight gain, gain efficiency (5.5%, P = 0.04), and tended to increase dietary net energy (3.2%, P = 0.06). In Trial 2, 96 Holstein steers (392 ± 4 kg) were used to evaluate the effect of tannin sources on growth performance. Treatments consisted of a steam-flaked corn diet supplemented with (1) no supplemental tannin, (2) 0.6% condensed tannin, (3) 0.6% hydrolysable tannin, and (4) a blend of 0.3% condensed and 0.3% hydrolysable tannin. Tannin supplementation tended to increase average daily gain (ADG, 6.8%, P = 0.08) and dry matter intake (DMI, 4%, P = 0.04). It is concluded that tannin supplementation promotes greater DMI, and hence, ADG of steers during the finishing feedlot phase. The basis for this effect on feed intake is not certain, but is apparently independent of potential tannin effects on metabolizable protein supply. Source of supplemental tannin (condensed vs. hydrolysable) have minimal effects on overall growth performance response to supplementation. ARTICLE HISTORY

“…Unfortunately, not all studies in this database reported comprehensive information on variables such as diet digestibility (NDF, CP, starch), which are important indicators of underlying model performance. The studies that reported observed whole-tract or rumen values for these variables were used to evaluate digestibility predictions, in addition to the literature data of Gilbery et al (2010), Yang et al (2010) and Mezzomo et al (2011).…”

“…Since the level of dietary NDF is much lower than that of starch, quantitatively, errors in NDF digestibility would have a smaller impact on the model results than errors in starch digestibility. The NDF digestibility was the most difficult component to predict accurately, reflecting the challenge of (2011) and Gilbery et al (2010), data used to evaluate starch digestibility came from Archibeque et al (2006Archibeque et al ( , 2007a and Yang et al (2010), and data used to evaluate pH came from McGinn (2005, 2006), Yang et al (2010), Mezzomo et al (2011) and Gilbery et al (2010).…”

“…The Dijkstra model bases rumen pH prediction on concentration of VFA in the rumen, but rumen pH is also influenced by buffers present in the diet, the cation exchange capacity of dietary cell walls and bicarbonate secretion through saliva production as influenced by effective dietary NDF content, or via bicarbonate dependent absorption of VFA [reviewed by Dijkstra et al (2012)]. Mezzomo et al (2011) suggested that high rumen pH values observed in their study, despite only 13% roughage in the diet, could be because of the use of sugar cane bagasse, which has high levels of effective fiber and stabilizes the rumen environment via increasing rumination and saliva production. Gilbery et al (2010) used chopped alfalfa, whereas some other studies in the CH 4 database used ground alfalfa, which would be much lower in effective fiber.…”

“…Protection of protein from microbial enzyme degradation can be carried out by linking the protein molecule to several chemicals such as formaldehyde (Spears et al 1985) and tannic acid (Mezzomo et al 2011;Coblentz & Grabber 2013). Experimental reports have proved the effectiveness of using formaldehyde to make undegradable protein in the rumen.…”

Dietary protein is digested to a certain extent in the rumen causing decreases its potency as source of amino acids for the animal. Dietary protein should mostly reach the intestines where the protein digestion takes place and absorption occurs in the form of intact amino acids and subsequently becomes nutrient deposition in muscles or milk. The higher muscle or milk protein synthesis, the higher the protein in the products of animal, as long as energy for the metabolism is available. Strategies of feeding rumen degradable versus undegradable protein in ruminant have become a research interest for decades. Technologies of dietary protein protection to reduce its degradability in the rumen by heating, chelating or coating have been developed. Key words:Protein, degradability, protection, rumen ABSTRAK Manipulasi Degradabilitas Protein di Dalam Rumen untuk Meningkatkan Produksi Ternak RuminansiaBerhubung sebagian dari protein di dalam pakan akan dicerna di rumen, maka pakan tersebut akan kehilangan fungsinya sebagai sumber asam amino bagi ternak. Protein pakan sebaiknya sebagian besar tidak didegradasi di dalam rumen sehingga terbawa sampai ke usus dimana akan terjadi proses hidrolisis dan penyerapan asam amino yang selanjutnya akan digunakan dalam deposisi nutrien di dalam jaringan tubuh ternak. Dengan adanya deposisi protein, produk ternak akan mengandung protein lebih tinggi dengan syarat energi untuk metabolisme tersedia. Strategi pemberian pakan mengandung protein terdegradasi versus protein tidak terdegradasi di dalam rumen ternak ruminansia sudah lama menjadi perhatian penelitian. Teknologi proteksi protein bahan pakan untuk menurunkan angka degradabilitasnya di dalam rumen melalui pemanasan, khelasi atau pelapisan telah dikembangkan.
