“…The decline in DM and CP rumen degradability with plant maturity has been reported widely (Aufrère et al, 2003;Yu et al, 2004;Rodrigues et al, 2004;Silva et al, 2008;Belachew et al, 2013;Ribeiro Junior et al, 2014). This reduction in disappearance could be explained by the decrease in protein content and increase in ADL content of grass with maturity.…”

The effect of the stage of maturity on the productivity, chemical composition, and ruminal degradability of Napier grass (Pennisetum purpureum) leaves under irrigation was studied. Samples were collected at three stages of maturity, at intervals of four weeks starting from the fourth week until the twelfth week (AprilJuly) after sprouting and then harvested to determine biomass. The stages of maturity had significant effects on longest leaf length per plant and plant height, but had no effect on number of leaves per plant and number of tillers. Dry matter (DM) increased significantly with maturity, while crude protein (CP) and fat content decreased significantly, with no significant effect on acid detergent lignin (ADL), ash, acid detergent fibre (ADF) and neutral detergent fibre (NDF). Maturity significantly decreased potassium, copper and sodium, while calcium and zinc increased significantly up to the intermediate stage, then declined toward the late stage of maturity. Maturity did not affect the magnesium, phosphorus, manganese and iron contents of the forage. Ruminal degradability of CP at 48, 72, 96 and 120 incubation hour decreased significantly with maturity, with no effect on all other incubation times for DM and CP. Maturity significantly decreased the soluble fraction (a) of DM, with no significant effect on other fractions of DM and CP. Effective degradability (%) of DM and CP decreased with maturity when the rate of passage increased from 2% to 8%. Napier forage should be harvested before maturity to retain its high nutrient content, and the degradability of DM and CP. ______________________________________________________________________________________

“…Ruminant productivity can be improved by combining basal feed with foliage of legume trees and shrubs available in the region as proposed by Olivares-Perez et al (2011). Legume tree forages are generally a source of better feed quality for grazing and as a supplement to increase the productivity of ruminants fed low-quality feed, especially under harsh environmental conditions (Belachew et al, 2013;Abdalla et al, 2014). Isah et al (2013) reported that supplementation with legume feeds for goats helped to improve utilization of low quality forage during the dry season.…”

ABSTRAKTujuan penelitian ini adalah untuk menganalisis pengaruh tingkat penggunaan daun kabesak putih (Acacia leucophloea Roxb.) Willd. dalam pakan terhadap konsumsi, kecernaan pakan dan pertambahan bobot badan kambing Kacang. Rancangan Acak Kelompok dengan 5 perlakuan dan 5 ulangan digunakan dalam penelitian ini. Perlakuan tersebut berupa 5 pakan konsentrat yang masing-masing mengandung 0, 10, 20, 30, dan 40% daun kabesak putih berdasarkan bahan kering (BK) secara berturutturut sebagai perlakuan T 0 , T 1 , T 2 , T 3 , dan T 4 . Semua pakan dibuat dengan kandungan protein kasar (PK) berkisar 11,5-12,5%. Masing-masing pakan konsentrat diberikan pada 5 ekor kambing Kacang jantan (umur 1-1,5 tahun, berat badan awal 16,7±5,0 kg) ditambah rumput lapangan kering dengan imbangan 60:40. Hasil penelitian menunjukkan bahwa konsumsi BK, BO dan PK pada kambing yang diberi pakan T 0 tidak berbeda nyata dengan kambing yang diberi pakan T 1 tetapi lebih tinggi (P<0,05) dibanding pada kambing yang diberi pakan T 2 , T 3 dan T 4. . Kecernaan BK, BO, PK dan SK serta pertambahan bobot badan kambing yang diberi pakan T 2 secara nyata lebih tinggi dan mempunyai konversi pakan lebih baik (P<0,05) dibanding kambing dengan pakan perlakuan lain. penelitian ini adalah tingkat penggunaan daun kabesak putih yang paling optimal dalam pakan konsentrat adalah sebanyak 20% (T 2 ).Kata Kunci: pakan, konsentrat, suplemen, produktivitas, legium pohon ABSTRACTThis study was conducted to analysis the effect of levels of white kabesak (Acacia leucophloea Roxb.) Willd. leaves in the diet on feed intake, digestibility and body weight gain of Kacang goats. The completely randomized block design using 5 treatments and 5 replications was used in this experiment. The treatments were 5 concentrate feeds containing different levels of white kabesak leaves i.e. 0, 10, 20, 30 and 40% in the dry matter (DM) basis (representing T 0 , T 1 , T 2 , T 3 and T 4 treatments, respectively). The feeds were set up to contain 11.5-12.5% of crude protein (CP). Concentrate feed and native grass was fed at ratio of 60 : 40 was fed to 5 local male goats (age 1-1 .5 years old and initial weight of 16.7±5.0 kg). The results showed that DM, organic matter (OM), and CP intake of T 0 was not significantly different from those of T 1 goats, but it was significantly higher (P<0.05) than those of T 2 , T 3 and T 4 . The DM, OM, CP, and crude fiber (CF) digestibility as well as body weight gain in T 2 goats were significantly higher (P<0.05) and had feed conversion ratio that was significantly better (P<0.05) compared to those of the other feed treatments. In conclusion, the most optimum level of white kabesak (Acacia leucophloea Roxb.) Willd. leaves used in concentrate feed for goat was 20 %.

“…The varietal range of the CP value of the stover in the current study was 78.1–101 g/kg DM. This exceeds the critical level of 70 g/kg DM CP required for optimum activity of rumen microorganisms and feed intake in ruminants (Belachew, Yieshak, Taye, & Janssens, ). In our study, we observed a large variation between varieties for stover in vitro digestibility traits.…”

This study evaluated the varietal variability and interrelationship of the grain and stover yields, and stover quality characteristics of four common vetch varieties (three improved varieties and one local variety) used on the Tibetan Plateau. Stover quality attributes determined included chemical composition, in vitro true digestibility of dry matter (IVTD) and neutral detergent fibre (dNDF). The improved varieties were superior to the local variety in grain yield, harvest index and potential utility index (PUI). The wide ranges in the proportions of leaf (24.3%–34.6%), pod (22.0%–45.6%) and stem (29.5%–44.7%) fractions were observed. Significant varietal differences (p < .001) were observed for the whole‐stover content of crude protein [CP; 78.1–101 g/kg dry matter (DM)], neutral detergent fibre (aNDF; 520–564 g/kg DM), acid detergent fibre (ADF; 520–564 g/kg DM), IVTD (597–658 g/kg DM) and dNDF (305–384 g/kg aNDF). The leaf fraction had the highest levels of CP, IVTD and dNDF, while the highest contents of aNDF and ADF were observed in the stem fraction. Canonical correlation analysis showed that significant (p < .001) correlations between the quality attributes of whole stover and proportions and quality attributes of stover morphological fractions. Pearson correlation between the grain and stover yield was negative and significant (r = −.295; p = .001), while the correlations between the grain/stover yield and stover quality traits were positive or non‐significant. Ranking of the varieties differed when grain yield, PUI and stover quality scores were investigated. Of the varieties tested, Lanjian No.2 has the best potential for use as a ruminant feed, as indicated by PUI and stover quality.
