Abstract

The existence of weeds significantly depressed productivity and quality of herbage. Physically weed controlled by defoliation could be expected to sustain quality and production of herbage, and able to control weeds expansion. The aims of study were to find the effect of interval defoliations of B. humidicola that invited by C. odorata and its effect on concentration of ammonia and volatile fatty acid of B. humidicola herbage (in vitro). The experiment was carried out at Laboratory of Agrostology, Faculty of Animal Science Bogor Agricultural University. In vitro digestibility of herbage was analyzed at Ruminant Nutrition and Feed Chemistry Laboratory, Faculty of Animal Husbandry, Padjadjaran University. Split plot design in time was used in the field experiment. The treatments were nine different planting methods and different defoliation intervals. Defoliation times are divided on the first defoliation and the last defoliation. The results showed that concentration of both ammonia and volatile fatty acid of herbage, which defoliated every 60 days were found significantly higher than those defoliated every 30 days and 90 days. Present and defoliation of C. odorata didn’t give significant effect on the concentration of ammonia and volatile fatty acid of B. humidicola herbage.

Abstract

Penelitian ini bertujuan untuk mengevaluasi mekanisme adaptasi tanaman legum pohon (Desmodium sp dan Leucaena leucocephala) yang diinokulasi dengan fungi mikoriza arbuskular (FMA) terhadap cekaman kekeringan. Penelitian ini dirancang menggunakan Rancangan Acak Lengkap (RAL) pola faktorial, faktor pertama adalah inokulasi FMA (tanpa inokulasi dan inokulasi dengan FMA), faktor ke-2 adalah kekeringan (disiram setiap hari, cekaman kekeringan). Parameter penelitian ini adalah kandungan air tanah (KAT), potensial air daun (PAD), kadar air relatif daun (KARD), dan bobot kering tanaman. Data dianalisis dengan analisis sidik ragam (ANOVA), jika terdapat pengaruh terhadap peubah yang diukur maka akan dilanjutkan dengan uji Duncan Multiple Range Test (DMRT). Tidak ada pengaruh interaksi (P>0,05) antara inokulasi FMA dengan cekaman kekeringan terhadap KAT, KARD, dan bobot kering tanaman ke-2 jenis legum pohon. Cekaman kekeringan menurunkan KAT, PAD, KARD dan bobot kering total pada tanaman legum pohon.

Abstract

This study aimed to evaluate the effect of cattle barns microclimate modification on the physiological response of beef cattles reared on peatland. This study used direct observation and experimental research methods. Microclimate modification is done by using asbestos material, gable roof type and roof height ≥3.5 meters, and vegetation arrangement. Data were collected through measurements of microclimatic parameters and physiological responses in the morning (06.30–07.30), at noon (11.30–12.30), and in the afternoon (16.30–17.30), with measurement intervals every month. The number of cattle barns observed was 46 units. The physiological parameter measurements involved 124 female beef cattle, consisting of 70 Bali and 54 crossbred cattle with physiological stages, gestating cows and lactation period. The results showed that modifying cattle barns and the surrounding environment can reduce the microclimate in the cattle barn as indicated by a decrease in THI from emergency to dangerous levels during the noondayand from dangerous to caution levels in the afternoon. The improvement in microclimate conditions was also followed by a decrease in the level of heat stress as indicated by a decrease in the physiological responses of cows.

Abstract

The composition of non-carcass thin-tailed sheep fed Indigefera zollingeriana with different rearing systems, was evaluated using twenty sheep with an average initial body weight of 18.3 ± 2.01 kg. The variables observed in this study included the weight of the head, feet, skin, tail, liver, spleen, lungs, heart, kidneys, rumen, reticulum, omasum, abomasum, intestines, empty viscera and omnetal fat. The design used in this study was a factorial completely randomized design (CRD) with five replications. Feed is treatment factor one (P1 = grass + commercial concentrate and P2 = grass + Indigefera zollingeriana) and maintenance is treatment factor two (SI = Semi Intensive and I = Intensive). The results of the study were analyzed by analysis of covariance. and the correction factor is the initial weight of the sheep. The results of this study showed that giving P2 to sheep resulted in lower tail weight but higher kidney weight (P<0.05). In addition, there was an interaction effect (P< 0.05) between treatments on the weight of theomasum and abomasum, where the sheep with P1I treatment had the highest omasum and abomasum weights, while the lowest omasum and abomasum weights were in the P2I treatment.
