    Estimasi dinamika populasi sapi potong yang dipelihara di areal perkebunan kelapa sawit di Kalimantan Selatan
    (J. Sains Dasar, 2014-09) Yudi, Adinata; Dicky, Pamungkas; Noor, Hudhia Krishna; Aryogi; J. Sains Dasar
    Usaha integrasi sapi potong dan tanaman kelapa sawit (integrasi tanaman ternak) perlu didukung dan dikembangkan. Penelitian ini bertujuan untuk menghitung estimasi dinamika populasi sapi potong yang dikelola oleh PT. KAL. Estimasi dinamika populasi dihitung menggunakan simulasi berdasarkan data populasi dan status fisiologis ternak serta daya dukung pakan di bawah tegakan sawit. Kapasitas terpasang berdasarkan daya dukung lahan adalah sebesar 2.066 ± 199 UT yang secara alami akan tercapai pada tahun 2029-2030. Pencapaian kapasitas optimum dapat pula dicapai secepatnya dengan cara mendatangkan sapi baru.

    Evaluation of the use of plant organic components and probiotics on ruminal characteristics and as a decrease of methane
    (IOP Publishing, 2021) Yenny, Nur Anggraeny; Dicky, Pamungkas; Mariyono; N H Krishna; R Antari; A S Putri; M N Apriliza; IOP Conference Series: Earth and Environmental Science
    The reduction of CH from the digestive tract of ruminants can be done through the use of organic components of plants such as tannins and saponins and the use of probiotics. This study aims to evaluate the addition of organic components and probiotics to the characteristics of rumen fluid and its ability to reduce CH in Ongole Cross Breed (PO) cattle. Sengon (Paraserianthes falcataria) leaf meal and Trembesi (Samanea saman) leaf meal are used as organic components due to their tannin and saponin content. Probiotics contain Acetoanaerobium notarae and Saccharomyces cereviseae. This research used total mixed ration as a feed. A total of 24 heads PO cattle were divided into 4 treatments, ie T1 = control treatment; T2 = T1 + organic components, T3 = T1 + Probiotics and T4 = T1 + organic components + probiotics. The research design was a randomized block design. The combination treatment of the addition of organic components and probiotic caused a decrease in the ratio of acetic acid to propionic acid percentage of acetic acid.

    A Growth Comparison of Ongole and European Cross Cattle kept by Smallholder Farmers in Indonesia
    (2022) Dicky, Pamungkas; Risa, Antari; D.E. Mayberry; D.P.Poppi
    Increasing beef production in Indonesia requires an increase in the productivity and profitability of smallholder cattle fattening enterprises. In East Java, smallholder farmers keep many different breeds of cattle for growing and fattening prior to slaughter, but there is no published information available about how the different breeds of cattle perform under village conditions.The aim of this research was to compare the growth performance of three common breeds of beef cattle during the dry and wet seasons at the smallholder farmer level. The three breeds of cattle monitored were: PeranakanOngole (Bos indicus)(PO; 26 in dry season and 22 in wet season), Ongole-Simmentalcross(Bos indicus/Bos taurus)(SimX; 35 in dry season and 28 in wet season), and Ongole-Limousincross (Bos indicus/Bos taurus)(LimX; 30 in dry season and 22 in wet season). Cattle were aged 1 to 2.5 years, and were kept by smallholder farmers in Pasuruan and Malang districts, East Java, Indonesia. Weight, girth and body condition score (BCS, 1-5 scale) of cattle were measured over 10 weeks in the dry season (July to September 2010) and 12 weeks in the wet season (December 2010 to March 2011). In each season, weight was measured three times and girth and BCS were measured five times.The composition and quantity of feedsoffered to cattle were also recorded. Changes in weight, girth and BCS were analysed by General Linear Models using SPSS programversion14.In both seasons, average daily weight gain of SimX (0.4 kg/d)and LimX (0.4 kg/d)was higher than that of PO (0.1kg/d). There was no difference in average daily weight gain between SimX and LimX cattle in either season. BCS of cattle increased during the wet season by 5% from an average 3.2 out of 5. In the dry season BCS decreased from 3.9 by 9%.Nutritive value of feed is likely to be higher in the wet seasoncompared to the dry season.Growth of all cattle breeds was lower than expected in both seasons. This was probably due to the high proportion of poor quality feeds such as rice straw in the diets (as fed basis, 48% at dry season and 78% in wet season). These results highlight the large discrepancy between what is expected from research on research stations and what is achieved on farm, and indicates the huge potential for improvement in production with better diet formulation.

    Rice straw, cassava by-products and tree legumes provide enough energy and nitrogen for liveweight maintenance of Brahman (Bos indicus) cows in Indonesia
    (Csiro Publishing, 2014) Risa, Antari; G. P. Ningrum; D. E. Mayberry; Dicky, Pamungkas; S. P. Quigley; D. P. Poppi; Animal Production Science
    The aim of this experiment was to test the effectiveness of two diets in increasing liveweight (LW) and body condition score (BCS) of Brahman cows in Indonesia. Diets were based on rice straw, with additional energy and nitrogen (N) provided in the form of onggok (a cassava by-product) plus urea or a tree legume. Thirty mature, non-pregnant, non-actating Brahman crossbred cows (288 kg LW, BCS 2/5) were allocated to one of two treatment groups. Cows were kept in individual pens for 21 weeks and offered one of two diets; (1) urea-supplemented rice straw ad libitum plus 10 g onggok DM/kg LW.day, or (2) untreated rice straw ad libitum plus 5 g onggok DM/kg LW.day and 5 g Gliricidia sepium DM/kg LW.day. The urea supplement provided no advantages over using locally available N sources such as gliricidia, with both supplement types meeting the rumen-degradable N requirements of the cows. Cows on both diets gained weight at a similar rate (0.19 kg/day) for the first 15 weeks of the experiment. Liveweight gain in Weeks 16–21 was only 0.04 kg/day, despite an increase in total feed intake and energy content of the diets compared with Weeks 1–15. Liveweight of cows stabilised during Weeks 16–21 at 304 kg, BCS 2.2. While our results demonstrate that Brahman cows can maintain LW on rice straw-based diets, they may not be able to maintain a BCS sufficient for good reproduction rates (i.e. BCS 3 or higher on 1–5 scale). Better quality diets containing higher levels of energy are required for cows to gain and maintain a suitable BCS.

    Supplementing mineral selenium and vitamin e in diets on in vivo digestibility, blood glucose, and urea levels of cows
    (IOP Conference Series: Earth and Environmental Science, 2022) Dicky, Pamungkas; Alif, Shabira Putri; Frediansyah, Firdaus; Retno, Widiyawati; Dicky, M. Dikman; IOP Conference Series: Earth and Environmental Science
    In such condition as of mating, pregnant and delivering calves, cows were often having deficiency in micro minerals, causing their reproductive functions to be less than optimal. The aim of this study was to determine the effect of Selenium and Vitamin E (SeVE) addition in diets on in vivo digestibility, blood glucose and urea levels. A total of 30 Ongole rossbred cows (I3-I4 Aged, Body Weight 423.8 _ 75.0 kg, and Body Condition Score 3.1 _ 0.2) were used in this experiment. The study was conducted for 13 weeks. Animals were prepared to be inseminated by the Belgian Blue straws. They were kept in individual cages and were divided into two treatments, namely (P0) = basal diets and (P1) = basal diets + SeVE. The diets given were elephant grass and concentrate (3% of body weight). The results showed that addition SeVE increased digestibility of organic matter and crude protein, increased blood Se and urea levels, but did not show significant effect on blood glucose levels. In subsequent observations, SeVE addition turned out to have a positive effect on the incidence of regnancy.
