Macerated Alfalfa Forage For Beef And Dairy Cattle

Sejumlah penelitian telah dilakukan untuk menyelidiki faedah pemecahan batang alfalfa pada saat dipanen di daerah prairi terhadap lama pengeringan, sifat-sifat nutrisi pada saat disimpan dan nilai nutrisi pakan. Alfalfa pada awal pertumbuhan bunga dipanen  menggunakan salah satu dari dua mesin. : mesin convensional, (CONV) atau dengan mesin pemecah batang yang mempunyai empat tingkat pemecahan (LIGHT : ringan,LIGHT + : agak berat, SEVERE : berat dan SEVERE+ : sangat berat). Selama pengeringan, perlakuan  LIGHT + s.d. SEVERE+ mencapai kadar Bahan Kering (BK) 45 % dan 80% dalam waktu masing-masing hanya sekitar 2 jam dan 9-11 jam, dibanding CONV, yang mencapai kadar BK tersebut berturut-turut dlm waktu 6 dan 54 jam. Padet sapi pedaging mengonsumsi BK silase 13 % lebih banyak dan memperoleh pertambahan  bobot badan harian 22.7% lebih berat (P<0.05) jika batang alfalfa dipecah pada saat dipanen(SEVERE), dibanding tidak (CONV) , pada awal pertumbuhan selama 21 hari. Sapi perah Holstein betina awal laktasi yang diberi ransum yang mengandung silase dan hay dari alfalfa yang batangnya dipecah pada saat dipanen memproduksi susu dengan kandungan gizi yang sama disbanding batang. Namun demikian, kelompok sapi yang diberi ransum yang mengandung alfalfa yang terpecah batangnya memberikan bobot hidup yang lebih berat dan nilai kondisi tubuh yang lebih baik (P<0.05) pada saat akhir penelitian laktasi selama 14 minggu.

Study on the Quality of Broiler Carcasses Stored at Room Temperature After Steaming Treatments

This research is conducted to study the effect of steaming time before marketing on quality and storage time of broiler carcasses. A Completely Randomized Design (CRD) with factorial 3 x 4 was used. The first factor was steaming time, i.e. steaming at 80˚C for 2 minutes, 4 minutes, and 6 minutes. The second factor was storage time at room temperature, i.e. initial condition, 4, 8, and 12 hours. The parameters observed were pH, water holding capacity, and total number of bacteria. Results showed that the interaction between steaming time and storage time had significant effect on pH, and  total number of bacteria. Storage time had significant effect on water holding capacity of broiler carcasses. It can be concluded that steaming at 80˚C before marketing significantly decreases total number of bacteria. Meanwhile, broiler carcasses stored for 8 hour at room temperature showed no significant decrease of carcass quality (pH, water holding capacity and total number of bacteria).

A Review: Livestock On-Station and On-Farm Trial

Scientist working in international livestock research are expected to be familiar with an interdisciplinary systems approach, and to work in multidisciplinary teams. The argument for this approach is that (1) discipline specialists are not equipped to understand the relationships between the components they focus on and the systems as a whole, (2) if the specialist operates in isolation from the other discipline, he/she is operating in isolation from the system and so the results may be irrelevant or, if applied, actually have a deleterious effect on the systems, (3) therefore, the specialist must understand the system through a  systems approach, a systems person, or the activities of a team. Applicants hoping to work in international livestock research are expected to have had project experience in the tropics, where the environment, culture, facilities and infrastructure  may be very different from that in Northern Europe. The purpose of this course is to familiarize student with the  multidisciplinary or interdisciplinary systems approach and to prepare them for their field projects in the tropics.

Sustainability of Forage Systems in Small Holder Dairy Cattle in The Plateau in East Java

Abstract. This study aimed to describe the sustainability of forage system in the small holder dairy cattle  in the plateau in East Java, in particular related to the nutrient content. The method used was survey (interviews, questionnaires, field observations and sampling) at the cooperation unit, farmers, livestock and farming location in one of the areas of dairy cattle cooperation in the plateau (Cooperation of SAE Pujon-Malang). The data obtained were analyzed through descriptive and regression statistics. The results showed that forage system dominantly given during dry and rainy seasons are elephant grass and corn stalks. Linear regression equation for the nutrient content of elephant grass is TDN= 40.516 + 1.404 CP, while corn trees is TDN= 56.212 + 0.740 CP. The conclusion showed that the dependent variable is largely influenced by external factors (environment). Improved continuity of availability of forage can be done by increasing the feeding system in the region (plateau) as well as the support from outside the region. Key words: plateau, dairy cattle, forage  Abstrak.

Influence of Non-fibrous Carbohydrate and Degradable Intake protein and Ruminal Fermentation ,Nutrien Digestion and performance of Local Sheep

The objective of current study was to evaluate the impact dietary non-fibrous carbohydrate ( NFC) and ruminally degradable intake protein (DIP) concentration have on ruminal fermentation , nutrient digestion and performance of local sheep. The animal had a mean of  liveweight 19.80 ±1.55 kg. four diets ,arranged in a 2x2 factorial ,were formulated to contain either 40 or 50 % NFC and 50 or 60 % of dietary crude protein as DIP .dietary DM contained 25 % Indonesian field grass and 75 % concentrate. Solvent –extracted or formaldehyd  2 % -treated soybean meal were used to alter DIP and corn or soybean hulls to alter NFC level. Percentage of  energy and NDF digestion was similar ( p<0,01) as DIP level decreased in the diets. The soybean hulls was fermentable and total VFA concentration in the rumen increased ( p<0.01), but N-NH3 concentration was decreased ( p<0.01) as DIP level decreased in the diets. Daily live weight gain ( 146.29±25.84 g) and body composition ( fat, water , protein and mineral) was similar ( p<0.05) among diets. The preponderance ruminal fermentation ,nutrient digestion and performance of local sheeps did not be improved by sincronization of energy and nitrogen release but may more likely be limited by either energy or nitrogen alone.

Voluntary Feed Intake and Growth of Local Sheep Fed on Road Side Grasses Following A 6-Week Feed Restriction Period

The purpose of this experiment was to investigate an adaptation time sheep to eat at a normal amount required by the local experiencing liveweight loss due to feed restriction, to investigate feed intake and feed digestibility and to investigate sheep growth following feed restriction. The experiment was conducted in The Experimental Farm of Faculty of Animal Husbandry, Unsoed. Twelve local sheep were randomly assigned to two different groups of treatment: namely, control (C) and restrictively Fed Animal (R). there were two periods through out the experiment, Period I (PI) and II (PII). During P I (6 week), Animals in group R were restrictively fed so that they lost live weight of approximately 15%. During P II Animals in group  R were than offered ad libitum. Whereas, animal in group C were fed ad libitum through out the experiment. The results of this experiment showed that animals in group R needed 17 days for adaptation to consume feed at a normal amount after they had experienced feed restriction for 6 weeks. Dry matter intake was not different between group C dan R. However, when it was expressed per metabolic live weight (g/Kg0,75), Dry matter intake for group R was significantly higher than that for group C (102.35 vs 91,79). Dry matter digestibility value for group R was higher than that for group C either during PI (62 vs 57%) or during PII (70 vs 61%). The rate of live weight gain was not different between C and R during period II. In conclusion, local sheep had capability of consuming more feed after resumption of full feeding for 17 days.
