“…The main effects of plant extract in the rumen are a reduction of protein and starch degradation, and an inhibition of amino acids degradation by a selective action on certain rumen microorganisms, especially some bacteria (Hart et al, 2008). Thus, the use of tCNSL might improve the total digestibility of CP, due to higher N flow to small intestine and as a consequence of a decrease of peptides and amino acids fermentation, due to lower deamination.…”

sUMMAryThe objective was to evaluate the inclusion of technical cashew nut shell liquid (tCNSL) in the concentrate for cattle fed on a high-grain diet on feed intake, ruminal and total apparent digestibility coefficients of nutrients, fermentation characteristics and microbial efficiency. Four Holstein steers (445 ± 23.39 kg of body weight) fitted with ruminal and duodenal cannulae were used. The diets had (in DM basis) 144 g kg-1 of crude protein and 799 g kg-1 of total digestible nutrients, with a forage to concentrate ratio of 15:85. The experimental design was a 4 x 4 Latin square with 10-day experimental periods. The diets consisted of 0; 300; 600 and 1200 mg of tCNSL in DM of the concentrate. Intake and total apparent digestibility coefficient of nutrients, on DM basis, were not affected by experimental diets. However, ruminal digestibility of ether extract showed quadratic response in which animals fed 0 and 300 mg tCNSL kg-1 of concentrate had the lowest values for ruminal digestibility. Ruminal ammonia nitrogen, plasma urea nitrogen and microbial efficiency were not affected by treatments. However, ruminal pH tended to increase when animals were fed with tCNSL. Objetivou-se avaliar os efeitos da inclusão do líquido da casca da castanha de caju (tCNSL) na dieta de bovinos alimentados com dietas ricas em grão, sobre a ingestão e o coeficiente de digestibilidade ruminal e total dos nutrientes; as características de fermentação ruminal, eficiência de síntese microbiana no rúmen e parâmetro sanguíneo, através do nitrogênio ureico plasmático. Foram utilizados quatro novilhos da raça Holandesa (445 ± 23,39 kg de peso vivo) providos de cânula ruminal e duodenal, recebendo uma dieta com 144 g kg-1 de proteína bruta e 799 g kg-1 de nutrientes digestíveis totais, com uma relação volumoso:concentrado de 15:85. O delineamento experimental foi o quadrado latino 4 x 4 com 10 dias de períodos experimentais. As dietas foram compostas de 0, 300, 600 e 1200 mg de tCNSL na matéria seca (MS) do concentrado. A ingestão e os coeficientes de digestibilidade aparente total dos nutrientes, com base na MS, não foram influenciados pela inclusão de tCNSL na dieta. O coeficiente de digestibilidade ruminal (CDR) do extrato etéreo apresentou resposta quadrática, em que os animais que consumiram 0 e 300 mg tCNSL d-1 apresentaram menores valores de CDR. O uso do LCCt não influenciou o nitrogênio amoniacal no rúmen, o nitrogênio ureico plasmático e a eficiência de síntese microbiana. No entanto, houve tendência de maior pH ruminal quando os animais consumiram o LCCt. PAlAvrAs-chAve AdicionAisAditivo. Cardol. Cardanol. Digestibilidade. Fermentação ruminal.

“…Tambahan pakan berupa tepung tersebut diberikan sebanyak 2% dari bobot tubuh sapi peliharaan, atau sebanyak 4% pada sapi laktasi (perah) yang perlu diberikan untuk melengkapi kebutuhan. Menurut Hart et al (2008), tambahan pakan tersebut akan mempengaruhi tingkat kemampuan mencerna oleh rumen sapi sehingga dapat mendukung tingkat asupan protein oleh tubuhnya. Pola manajemen pakan seperti ini merupakan teknologi yang dapat digunakan di dalam mengembangkan pola adaptasi akibat perubahan iklim, sehingga produktivitas ternak dapat dipertahankan.…”

INTISARISumber daya flora lokal untuk pakan memiliki nilai penting, khususnya untuk ketahanan masyarakat petani di dalam menghadapi perubahan iklim global. Ketersediaan hijauan pakan untuk ternak pada ekosistem lahan kering tergantung kepada ketersedian air. Dampak perubahan iklim dirasakan pada bergesernya pola curah hujan, bahkan terhadap mulainya masa musim kering. Hal tersebut harus diantisipasi dengan kesiapan masyarakat lokal di dalam memahami ketersedian pakan dan pengelolaannya pada masing-masing musim. Di kawasan Bali Bagian Timur dan kawasan Nusa Tenggara (Barat dan Timur) iklim kering tahun 2004 menyebabkan krisis pakan. Mengacu kepada permasalahan tersebut di atas, penelitian telah dilakukan dengan tujuan inventarisasi sumberdaya hayati flora potensial di lahan kering. Fokus bahasan dilakukan berdasar kepada hasil survei dan pengumpulan data sekunder. Diperoleh 22 tanaman yang dapat dimanfaatkan untuk hijauan (forage feed) yang materialnya berlimpah pada musim hujan; sedangkan 15 ragam sumber pakan lainnya dapat dijadikan pakan awetan (silage) maupun pakan hijauan pada musim peralihan dan sepanjang musim kering. Hasil analisis menunjukkan bahwa saat ini yang perlu dilakukan adalah introduksi teknologi fermentasi silase untuk pengawetan pakan untuk persediaan musim kemarau. Terkait dengan pengembangan teknologi tersebut maka dilakukan kajian terhadap peran mikrobia penghidrolisis senyawa polimer dan proses fermentasi dengan keberadaan mikrobia GRAS (Generally Recognized as Safe) yang diawali oleh peran Lactobacillus plantarum. Hasil kajian dapat menjadi acuan dalam mengatasi dampak perubahan iklim di wilayah lahan kering, melalui aplikasi teknologi mikrobia fungsional pada pengelolaan pakan ternak sapi petani lokal yang berskala kecil.

“…Takashi (6) reportó que la producción de metano en rumiantes de países en vía de desarrollo puede ser alta, debido a que en sus dietas tiende a haber una falta de nutrientes que resultan críticos para un crecimiento microbiano eficiente en el rumen. Se ha reportado que los extractos vegetales disminuyen la producción de metano decrease in rumen methanogens (3). One of the most important goals of stock breeders is manipulation of rumen microbial ecosystem to improve ruminant performance and to reduce methane emissions generated by ruminants.…”

Objective. The aim of the study is to determine the effect of different plant essence oil supplementation to TMR, concentrate and hay on methanogenesis and at 2, 8 and 24 hours (h) using in vitro gas production technique in cattle. Material and methods. Three fistulated Holstein dairy cows were used for rumen fluid collection for application of in vitro gas production technique. Four essence oils (T. vulgaris, O. vulgare, S. aromaticum, Z. officinale) were used as plant extracts. Results. Essence oil supplementation, particularly at increased doses, significantly decreased methane production for TMR, concentrate and hay at 8 and 24 h compared to negative and positive control groups (p<0.05). Among all plant extracts, Syzygium 200 ppm supplementation resulted the lowest methane production values(p<0.05). While methane production at 24 h in positive control groups were recorded respectively as 10.45, 10.75 and 10.07 for TMR, concentrate and hay, the values in Syzygium 200 ppm group were recorded respectively as 1.65, 3.28 and 1.98 for these feed groups. Conclusions. The findings of the study indicate that increased doses of essence oil supplementation significantly decrease methane production in ruminants. Hence, it is suggested that essence oil will be highly beneficial in ruminant nutrition.
