Triticosecale Wittmack

The objective of this study was to evaluate the ruminal degradability of dry matter and crude protein of high moisture triticale silage ensiled with different chemical and biological additives. Urea, sodium benzoate and an enzyme-bacterial inoculant were used as treatments. Four samples from each treatment were incubated in rumen on four sheep. Effective degradability was estimated for ruminal passage rate of 2%, 5% and 8% hour-1. Bayesian procedures were used to estimate potential degradation parameters in situ. The high moisture triticale silage with urea showed highest value for the soluble fraction (70.46%) and the best effective dry matter degradability, with a passing rate of 2% h-1 (90.63%), of control silage at other rates of passage. In relation to control silage, the addition of sodium benzoate and enzyme-bacterial inoculant decreased the effective degradability of dry matter, regardless of rate passage evaluated. Due to high solubility of urea, the silage added with this additive had the highest soluble fraction of crude protein (76.42%). The addition of enzyme-bacterial inoculant accelerated the ruminal passage rate of dry matter and protein to 0.26 and 0.20% h-1, respectively, providing less potential degradability of both in relation to other silages. As enzyme-bacterial inoculation reduces rumen degradability of crude protein, it tends to increase the availability of amino acids for intestinal absorption. The addition of urea to high moisture triticale silage may be recommended for sheep feeding at a low level of consumption, as it improves the effective dry matter degradability.

The aim of this study was to determine the digestion of dry matter (MS), crude protein (PC) and amino acids (AA) in dairy cows. Two cannulated cows were used for the determination of passage rate (Kp), in situ ruminal degradability (DR) and intestinal digestibility (DI) by abomasal catheter. The data to calculate Kp was analyzed with NLIN procedure by SAS, and descriptive statistics for DR and DI of MS, PC and AA from Kikuyu grass (Pennisetum clandestinum), a commercial supplement and two sources of rumen-protected AA. The study showed a Kp and a ruminal retention time of 0.036 h-1 and 27.4 h. The highest values from DR of MS and CP were from Kikuyu grass (69.0 and 61.8%) and concentrate (84.7 and 77.2%), followed by MetP (60.2 and 66.7%) and LysP (6.72 and 11.4%). The highest percentages of rumen indegradable amino acids (AADR) were from Kikuyu and concentrate, varying between 58.7 and 68% in forage, and 76.1 and 82.9% in the concentrate. The DR was 11.5 and 65.8% in LysP and MetP, respectively. The DI of AA (%AADR) varied between 42.3 and 77.4% for Kikuyu and 42.2 and 59.3% for concentrate. The values for the protected amino acids were 42.1 for LysP and 58.6 for MetP.

Ruminal Degradability

The purpose of this study was to determine the ruminal degradability of dry matter, crude protein, neutral detergent fiber and their fractions, contained in regrowth of mulberry at 56, 84 and 112 days. The degradation of leaves, stems and the whole plant was calculated. The potential degradability of these three components diminished as the regrowth aged. The soluble fraction of the dry matter was reduced from 29% to 25% in the leaves and from 27% to 19% in the stems between the 56th and the112th day. The degradable fraction in the stem remained constant (61-63%) on the three measuring days, with ruminal degradation levels of 14%, 10% and 9%/h respectively. In the stem the degradable fraction diminished from 42% to 30% between the 56th and 112th day, with degradation speeds of 8.4%, 6.7 % and 5.3%/h. The soluble crude protein diminished with age from 41% to 33% in the entire plant and the degradable fraction remained constant between 49% and 51%. The degradation rate was higher than 9.4%/h. The neutral detergent fiber had a degradable fraction of 71%, 62% y 43% on the 56th, 84th and 112th day, with degradation rates of 13%, 10% y 9%/h respectively. The degradation of the neutral detergent fiber began in the rumen with a lag time of 1.5 to 3.2 hours.

To evaluate the bromatological composition and ruminal degradability of dry matter (DM), crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber (ADF) of Xaraés palisade grass (Urochloa brizantha ‘Xaraes’ syn Brachiaria brizantha) under grazing in integrated crop, livestock (ICL), and forest (ICLF) systems, we conducted an in situ degradability trial in randomized blocks with three non-lactating 3/4 Gyr × 1/4 Holstein cows, provided with ruminal cannula. The management of Xaraés palisade grass was similar in both systems, differing only regarding shading in the ICLF system provided by eucalyptus trees (average 65% crown cover). Grass samples were incubated for 0, 3, 6, 9, 12, 24, 36, 48, 72, and 96 hours. Considering the passage rate 2% h-1, the Xaraés palisade grass of ICL system had greater NDF effective degradability in relation to ICLF (46.38% vs 44.98%). However, the palisade grass CP potential degradability was greater in the ICLF than in the ICL system (68.92% vs. 65.40%). The presence of trees in the pasture has effect on nutritional traits of the Xaraés palisade grass, increasing its protein content and degradability and reducing its fiber degradability.

The aim of this study was to evaluate the chemical composition and ruminal degradability of the dry matter (DM), crude protein (CP) and neutral detergent fiber (NDF) of fruit residues. Three fistulated sheep were held collectively in a pen, and fed daily with the studied residues in a diet consisting of canarana grass (Echinochloa pyramidalis) and a concentrate of corn and soybeans. The animals were allowed an adjustment period of seven days. The residues were dried in the sun, crushed in a forage machine, sorted using a 4.0-mm sieve, and incubated for 3, 6, 12, 24, 48, 72, and 96 h using nonwoven bags (weight 60g/m2, 14 ×12 cm²). Chemical analyses of the residues were performed using a randomized block experimental design with split plots. The cherimoya and tamarind residues showed the highest concentrations of CP (12.66% and 11.79%) the ether extract of cherimoya residue was the highest at 22.30%stands out the sour soup residue. The cashew and guava residues showed the highest levels of lignin (22.13 and 18.34%). The effective degradability of DM for the pineapple and tamarind residues to a passage rate of 5%/h were 53.04% and 42.61%, respectively. The guava, cherimoya, and cashew residues showed lower values at 19.16%, 26.86%, and 29.21%, respectively. The cherimoya, guava and pineapple residues showed the highest values of potential degradability for CP at 87%, 81%, 86.02% and 90.94%, respectively, with an average effective degradability of 50.0% at the rate of 5%/h. The pineapple (35.38%) and tamarind residues (34.49%) showed higher values of the effective degradability of NDF at a passage rate of 5%/h. Among the studied residues, the pineapple residue showed the greatest potential for use in animal feed based on chemical composition and rates of degradability.

Ruminal Degradability

One factor that may interfere with rumen fermentation is the physical form of feed, because of the colonization by bacteria during processing. Here, we aimed to perform a meta-analysis and evaluate the in situ ruminal degradability of energy feeds with distinct physical forms (grain vs. meal). We created a database, comprising 39 treatments from 12 studies conducted in Brazil, and focused on parameters for the potential and effective degradability of dry matter (DM) and crude protein (CP) of energy feeds. The results showed that there was no difference (P > 0.05) in any of the degradability parameters of DM and CP between the grain and meal. However, the readily soluble fraction of DM in the grain showed a higher degradability trend (P = 0.0888). Overall, it was concluded that the processing of energy feeds does not modify the degradability parameters of DM and CP, and that further studies need to be conducted in Brazil to evaluate the in situ ruminal degradability of starch.

This study evaluated the chemical composition and ruminal degradability of dry matter (DM), neutral detergent fiber corrected for ash and protein (NDFap) and crude protein (CP) in byproducts of African oil palm (palm cake, kernel or fiber), macaúba (pulp cake and kernel cake), acai (acai fruit), babassu (kernel cake) and pineapple (peel, crown and bagasse silage). Nineteen rumen-fistulated sheep were kept in individual stalls, receiving a daily diet composed of elephant grass silage and corn and soybean concentrate. After preparation in nylon bags, the byproduct samples were incubated for 0, 3, 6, 12, 16, 18, 24, 48, 72, 96, 120 and 144 hours, with three replicates of each ingredient per incubation time. The divergence between the protein nutritional value and energy nutritional value, based on discriminatory variables between groups, was estimated by cluster analysis. The effective degradability of DM, NDFap and CP for the different byproducts was, respectively, 35.9, 26.9 and 59.0% for palm cake; 48.3, 34.3 and 76.4% for palm kernel; 21.1, 6.6 and 50.3% for palm fiber; 34.3, 15.0 and 52.8% for macaúba pulp cake; 58.1; 63.0 and 51.6% for macaúba kernel cake; 49.7, 49.6 and 41.8% for babassu cake; 53.4, 40.5 and 79.8% for pineapple bagasse silage; and 21.3, 17.0 and 38.9% for acai fruit. Based on their NDFap and CP characteristics, the feeds were clustered in up to four different groups.

ABSTRACT The objective of this study was to evaluate the nutritive value of sugarcane silage with or without inoculation with P. acidipropionici or L. buchneri, over three fermentation periods. The experimental design was completely randomized in a 3 x 3 inoculant by fermentation period factorial arrangement (without inoculant, inoculant 1, inoculant 2; x three fermentation periods, 10, 60, 90 days). Values of pH, dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), hemicellulose (HEM) and lignin were determined and in situ DM degradability profiles were modelled for parameters a, b and c, potential degradation (A) and effective degradability (ED). The 90 day fermentation yielded a lower pH for both inoculants. There was an interaction between inoculant and fermentation period (P < 0.05) for DM content, with a reduction in silage DM without the additive at 90 days. The CP, HEM, ADF and lignin contents of sugarcane were not influenced by the treatments. The addition of P. acidipropionici provided the lowest NDF content at 10 days and presented a higher fraction a, potential degradation and ED. At 60 days, there was no variation in soluble fraction, the control silage showed a higher fraction b, higher potential degradation and ED. At 90 days of fermentation, L. buchneri silages presented a higher fraction a, degradation rate and DE and a higher b value was obtained in the silage without inoculant. Inoculants are effective in maintaining the silage DM content and nutritional value during prolonged fermentation periods.
