Abstract

his research was carried out in two locations, namely in the smallholder dairy farms SAE Cooperative area, Pujon District, Malang Regency from August to October 2021. Nutrient contents analysis using the proximate method and digestibility In Vitro using the In Vitro digestibility method by Tilley and Terry (1963) were carried out at the Laboratory of Nutrisi dan Makanan Ternak (NMT) of the Faculty of Animal Science, Universitas Brawijaya, Malang from November 2021 to April 2022. This study aims to evaluate the nutrient contents and in vitro digestibility of dairy cattle feed used by smallholder farms of SAE Cooperative area, Pujon District, Malang Regency.

English Abstract

This research was carried out in two locations, namely in the smallholder dairy farms SAE Cooperative area, Pujon District, Malang Regency from August to October 2021. Nutrient contents analysis using the proximate method and digestibility In Vitro using the In Vitro digestibility method by Tilley and Terry (1963) were carried out at the Laboratory of Nutrisi dan Makanan Ternak (NMT) of the Faculty of Animal Science, Universitas Brawijaya, Malang from November 2021 to April 2022. This study aims to evaluate the nutrient contents and in vitro digestibility of dairy cattle feed used by smallholder farms of SAE Cooperative area, Pujon District, Malang Regency. The materials used in this study were all feed stuff given to the smallholder dairy farms in the SAE Cooperative Pujon area which included forage and concentrates, as well as rumen fluid obtained from the Gadang Slaughterhouse. In addition, tools and chemicals for nutrient contents and digestibility in vitro analysis. Data were collected by conducting direct observations and interviews with smallholder dairy farmers (respondents) in the SAE Cooperative area, Pujon District, Malang Regency. The method in determining the respondents is purposive sampling, namely by considering farmers who have dairy cows that have been artificially inseminated (AI) once. The measured variables consist of Dry Matter (DM), Organic Matter (OM), Crude Protein (CP), Crude Fiber (CF), Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), Dry Matter Digestibility (DMD), Organic Matter Digestibility (OMD), and Crude Protein Digestibility (CPD). The results of observations on smallholder dairy farmers in the SAE Cooperative Pujon area showed that the feed stuff provided by smallholder dairy farms in the SAE Cooperative Pujon area consisted of forage and concentrate. The forage provided consists of Napier grass, Maize stover, calliandra, avocado leaves, and carrot leaves. The concentrate is given consists of SAEPRO concentrate, cassava peels, cassava pulps, pollard, and expired bread. Napier grass and Maize stover are foraged that are mostly given by smallholder dairy farmers to dairy cattles, and SAEPRO concentrate and cassava pulp are mostly given by smallholder dairy farmers in the SAE Cooperative Pujon area. Based on the analysis, the value of nutrient content and digestibility of the forage given to smallholder dairy farms in the SAE Cooperative Pujon area was obtained. The nutrient content of Napier grass is DM 24.93%, OM 85.67%, Ash 12.33%. CP 12.65%, CF 29.24%, ADF 34.66%, NDF 50.83%, with digestibility 47.89% DMD, 38.15% OMD, and 45.94% CPD. The nutritional value of Maize stover is DM 36.30%, OM 91.21%, Ash 8.79%. CP 9.77%, CF 26.95%, ADF 33.48%, NDF 60.60%, with digestibility 37.93% DMD, 27.71% OMD, and 52.58% CPD. Nutrient content of calliandra is DM 32.33%, OM 94.73%, Ash 5.27%, CP 20.71%, CF 15.48%, ADF 19.27%, NDF 27.50%, with digestibility 43.76% DMD, 32.99% OMD, and 36.60% CPD. The nutrient content of avocado leaves is DM 43.96%, OM 93.67%, Ash 6.33%. CP 12.25%, CF 25.01%, ADF 38.01%, NDF 46.86% with digestibility 26% DMD, 28.69% OMD, and 28.91% CPD. The nutrient content of carrot leaves is DM 13.08%, OM 82.99%, Ash 17.01%. CP 13.50%, CF 22.77%, ADF 3.51%, NDF 41.99%, with digestibility 45.12% DMD, 34.90% OMD, and 50.60% CPD. As for the concentrate given at smallholder dairy farms in the SAE Cooperative Pujon area. The nutrient content of SAEPRO concentrate was DM 81.93%, OM 90.11%, and Ash 9.89%, CP 14.29%, CF 19.05%, ADF 24.41%, NDF 44.49%, with digestibility 51.46% DMD, 46.28% OMD, and 50.24% CPD. The nutrient content of cassava pulp was 26.83% DM, 98.27% OM, 1.73% Ash, 1.01% CP, 13.06% CF, 23.88% ADF, and 38.80% NDF with digestibility was 45.93% DMD, 40.76% OMD, and 46.41% CPD. Nutrient cassava peels contained 22.64% DM, 95.03% OM, 4.97% Ash, 4.82% CP, 15.57% CF, 22.65% ADF, and 35.32% NDF with a digestibility of 69.86% DMD, 67.22% OMD, and 57.70% CPD. The nutrient content of pollard is 77.22% DM, 95.69% OM, 4.31% Ash, 18.28 CP, 14.60% CF, 11.59% ADF, and 37.91% NDF with a digestibility of 59.25% DMD, 52.96% OMD, and 59.54% CPD. The nutrient expired bread contains 71.55% DM, 98.34% OM, 1.66% Ash, 10.23% CP, 2.17% CF, 0.15% ADF, and 0.63% NDF with a digestibility of 82.79% DMD, 85.56% OMD, and 84.66% CPD. This study concluded that the forage feeds that are widely used in smallholder farms in the SAE Cooperative area are Napier grass and maize stover, while the concentrates that are widely used are SAEPRO concentrate and Cassava pulp. The results of the analysis of nutrient content are still within the normal range or are still suitable for use as feedstuff for dairy cattle
