The objective of the present study was to evaluate the in vitro and in situ dry matter degradation by including cacay cake (Caryodendron orinocense) on a diet based on Brachiaria dictyoneura. The experiment was developed in an animal nutrition laboratory on the Animal Sciences Faculty at the Universidad de Ciencias Aplicadas y Ambientales, Bogotá, Colombia, in July 2015. Four treatments were evaluated: B. dictyoneura, cacay cake and two mixtures of B. dictyoneura: cacay cake (80:20 and 60:40). The chemical composition and the in vitro and in situ degradability of the dry matter and the crude protein, at 48 hours were determined. The variables were analyzed through a complete randomized design with four treatments. The inclusion of cacay cake decreased the cell wall-associated with carbohydrate concentration and increased the higher digestibility nutrients; the crude protein and dry matter, in situ and in vitro degradability increased 22, 6 and 38%, respectively. In conclusion, the inclusion of cacay cake on a diet of B. dictyoneura improves dry matter degradation in vitro and in situ conditions.

This study aimed to evaluate the nutritional value of legumes leucaena and desmodium preserved in hay and silage form. We used a completely randomized design in a 2x2 factorial arrangement with two bulky conservation methods (hay and silage) and two legumes (leucaena and desmodium). For the bulky characterization was determined chemical composition and total digestible nutrients (TDN). For assessing the nutritional value, analysis of in vitro dry matter digestibility (IVDMD) and cell wall digestibility (IVCWD), and in situ effective degradability of dry matter (EDDM) and crude protein (EDCP) were performed. Data were submitted to ANOVA and Tukey test at 5% probability. Due to the characteristics of each specie leucaena presented a higher crude protein (CP) and TDN content compared to desmodium and lower fibrous fractions. The IVDMD presented interaction between the conservation form and forage (P<0.05), where leucaena hay was higher than the others treatments. The IVCWD also presented interaction (P<0.05), and the best values were obtained for leucaena silage. EDDM was superior in leucaena compared to desmodium (P<0.05). Regarding the method of preservation, the EDDM was higher in hay compared to silage. For the EDCP there was an interaction between conservation method and forage, where leucaena silage and hay were similar (P<0.05), but higher than other treatments. Thus, leucaena has a nutritional value higher than desmodium and the conservation of legumes in the hay form presented a higher nutritional value to the conserved as silage.

The amaranth plants showed high potential feed value as forage for ruminants. An in-depth study of this plant, particularly in cattle, will help extend its utilization as an alternative protein and fiber feed source in cattle feeding. In this study, the nutrient compositions of three different species of amaranth, Amaranthus caudatus L., Amaranthus cruentus L., and Amaranthus hypochondriacus L.—two varieties for each species, A.ca 74, A.ca 91, A.cu 62, A.cu 66, A. hy 30, and A. hy 48—were evaluated. The in vitro technique was used to evaluate the fermentation characteristics such as total gas production, total volatile fatty acids (VFA) concentration, pH, and ammonia concentration of the rumen fluid. Moreover, the effective degradabilities of dry matter (EDDM) and crude protein (EDCP) of the amaranth forages were determined through in situ bag technique. The amaranth forages: A. caudatus, A. cruentus, and A. hypochondriacus showed better nutritive value than the locally produced forages in Chungcheong province of Korea. The CP of the amaranth ranged from 11.95% to 14.19%, and the neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents ranged from 45.53% to 70.88% and 34.17% to 49.83%, respectively. Among the amaranth varieties, A. hypochondriacus 48 showed the most excellent ruminant feed nutrient quality (CP, 14.19%; NDF, 45.53%; and ADF, 34.17%). The effective degradabilities of dry matter (EDDM; 33–56%) and crude protein EDCP (27–59%) of the amaranth were lower compared to other studies, which could be due to the maturity stage at which the forages were harvested. Nonetheless, A. hypochondriacus 48 showed the highest EDDM (56.73%) and EDCP (59.09%). The different amaranth species did not differ greatly in terms of total VFA concentration or molar proportions, total gas production, or ammonia-N concentration. The high nutrient composition, and highly effective degradability of dry matter and crude protein, coupled with the favorable fermentation characteristics, suggest that the amaranth forages showed good to excellent feed quality for cattle.

<p>Para cuantificar la degradación <em>in situ </em>de tejidos vegetales y su relación con la composición química de especies forrajeras se seleccionaron láminas foliares de las gramíneas <em>Bouteloua repens </em>y <em>Bothriochloa pertusa </em>y foliolos de las leguminosas <em>Stylosanthes scabra</em>, <em>Desmodium barbatum </em>y <em>Tephrosia cinerea</em>. En el rumen se incuba­ron muestras de 10 mm de largo durante 0, 12, 24, 48 y 72 horas; para la lectura del área residual se digitalizaron ocho tejidos. A las 24 y 48 h de incubación <em>B. pertusa </em>presentó relaciones positivas entre la degradación de la epidermis adaxial (EA) y la FDN (R2= 90,2), entre el mesófilo y la DIVMS (R2=80,1), y entre los tejidos len­tamente degradables (TLD) y la FDA (R2= 83,9); y relaciones negativas entre EA y DIVMS (R2= –73,1), los TLD con la DEF (R2= –74,3), la EA con la PC (R2= –87,6), y el esclerenquima con la DIVMS y la PC (R2= –84,3 y R2= –90,8). Después de 72 horas de incubación las mayores áreas residuales en gramíneas fueron la estructura kranz entre 34,2% y 36,5%, el mesófilo entre 20,9% y 21,4%, el xilema de 11,5% a 17,1% y la EA entre 11,8% y 13,9%; no obstante el esclerénquima se relacionó estrechamente con indicadores de calidad nutricional. Las gramíneas obtuvieron mayores porcen­tajes de tejidos no degradables que las leguminosas; por lo tanto, la DIVMS y la DEF fueron menores. Entre las leguminosas, <em>S. scabra</em>, presentó la mayor digestibilidad de los tejidos rápidamente degradables, tanto en sequía como en lluvia; en la época seca se incrementó en 134,6% la degradación de estos tejidos. Adicionalmente, en esta especie el área residual de los taninos no presentó relación directa con la degra­dación del mesófilo. En leguminosas la tasa y extensión de la degradación de las epidermis se incrementaron marcadamente a mayor tiempo de incubación, presen­tándose diferencias entre especies, situación que no exhibieron las gramíneas. En <em>D. barbatum </em>la degradación de la EA se asoció con la DIVMS y la DEF, explicando en 77,4% y 72,95% estos porcentajes; de igual manera se reportaron relaciones negati­vas entre la degradabilidad de la epidermis y los porcentajes de FDN, FDA, lignina y taninos (R2= –0,76; R2= –0,79; R2= –0,53 y R2= –0,76, respectivamente).</p><p> </p><p><strong>Microbial <em>in situ </em>degradation of grasses and legumes leaf tissues and its realtionship with nutritional quality and precipitation</strong></p><p>A study was conducted to measure the <em>in situ </em>de- gradation of plant tissues and its relationship with forage chemical composition in leaves of the grasses <em>Bouteloua repens </em>and <em>Bothriochloa pertusa </em>and of the legumes <em>Stylosanthes scabra</em>, <em>Desmodium barbatum </em>and <em>Tephrosia cinerea</em>. Forage samples of 10 mm in length were incubated in the rumen for 0, 12, 24, 48 and 72 h and tissue residual area was determined by reading the residual area in eight digitalized leaf samples per forage. In <em>B. pertusa</em>, after 24 and 48 h of incubation there were positive relations between the degradation of adaxial epidermis (AE) and the neutral detergent fiber (NDF, R2 = 90.2), between mesophyll and in vitro dry matter degradability (IVDMD, R2 = 80,1), and between slowly degradable tissues (SDT) and the acid detergent fiber (ADF, R2 = 83.9); and negative relationships between AE and IVDMD (R2 = -73,1), between SDT and effective dry matter degradation (EDMD, R2 = -74,3), between AE and crude protein (CP, R2 = -87,6), and between sclerenchyma and IVDMD with CP (R2 = -84,3 and R2 = -90,8, respectively). After 72 h of incubation, the greater residual areas in grasses were the Kranz structure (34.2% to 36.5%), mesophyll (20.9% to 21.4%), xylem (11.5% to 17.1%) and AE (11.8% to 13.9%). The area of sclerenchyma was related close­ly to indicators of nutritional quality. Overall, the grasses had greater content of non-degradable tis­sues than the legumes; therefore, their IVDMD and EDMD were lower. Among the legumes, <em>S. scabra </em>showed the greater digestibility of rapidly degrada­ble tissues, both during the rainy and dry seasons. At the dry season, the degradation of these tissues increased by 134.6%. Additionally, in this legume, the content of tannins did not have a direct relation­ship with the degradation of mesophyll. The rate and extension of the degradation of epidermis in legumes, were noticeably increased with increasing length of incubation, existing differences between species, a situation which was not observed in the grasses. In <em>D. barbatum</em>, the degradation of the AE was positively associated with both the IVDMD and EDMD (R2 = 77,4% and 72,95%, respectively). On the other hand, the degradability of epidermis and the percentage of NDF had negative relations with ADF, lignin and tannins (R2 = -0,76; R2 = -0,79; R2 = -0,53 and R2 = -0,76, respectively).</p>

Dry matter (DM) degradation of wheat straw (WS), barley straw (BS), lucerne hay (LH) and maize silage (MS) was determined using two different techniques: (i) in vitro gas production and (ii) nylon bag degradability technique. In vitro gas production and in situ DM disappearance were measured after 3, 6, 12, 24, 48, 72 and 96 hours of incubation. In situ and in vitro DM degradation kinetics was described using the equation y = a + b (1 &ndash; e<sup>ct</sup>). In all incubations there were significant (P &lt; 0.001) correlations between gas production and in situ DM disappearance or estimated parameters ((a + b)<sub>ga</sub><sub>s</sub> and (a + b)<sub>is</sub> or (a + b)<sub>gas</sub> and EDMD<sub>is</sub>) whereas there were no significant (P &gt; 0.05) correlations between c<sub>gas</sub> and c<sub>is</sub> or b<sub>gas</sub> and b<sub>is</sub>. Gas production from the insoluble fraction (b) alone explained 98.3% of the variation of EDMD. The inclusion of gas production from the quickly soluble fraction (a) and rate constant (c) of gas production in the regression equation improved the accuracy of EDMD prediction. The correlations between the results of both methodologies seem to be sufficiently strong to predict degradability parameters from gas production parameters. It was concluded that the in vitro gas production technique has good potentiality to predict in situ DM disappearance and some DM degradation parameters. &nbsp; &nbsp;

The objective of this research was to evaluate the effect of three concentrations (3, 6, and 9%) of forage turnip (Raphanus sativus) and physic nut (Jatropha curcas) cakes on dry matter, crude protein, ether extract, neutral detergent fiber, acid detergent fiber, lignin, acid detergent insoluble nitrogen neutral detergent insoluble nitrogen contents, in vitro dry matter digestibility, pH values and concentrations of N-NH3 in elephant grass silages. It was used an entirely randomized design in factorial arrangement [(2×3)+1]. Experimental PVC silos were used and ensiled material was kept for 62 days. The addition of cakes increased the dry matter contents (P<0.05). The fibrous fractions were reduced (P<0.05) with the inclusion of cakes during the grass ensilage and the CP contents increased (P<0.05). The forage turnip cake provided the same pH and N-NH3 values in ideal levels and the physic nut, added to 9%, increased those values (P<0.05). IVDMD was reduced (P<0.05) when the cakes were added. These co-products can be used in small amounts for elephant grass ensilage in order to provide improvement in chemical and fermentation characteristics of the silages. Nevertheless, physic nut cake shows limitations for its use in animal feeding due to the presence of toxic compounds, making necessary studies for their identification and elimination.
