The Various of Complete Feed Block for Dairy Cattle

Abstract. The effect of three forms of complete feed blocks (CFB) for dairy cattle was evaluated. The form of various CFB were cube, cylinder and ball.  The CFB was prepared from napier grass specific tolerance acid soils and concentrate in 50:50 ratio.  The research used experimental method with randomized block design.   Sixteen dairy cattle were used in this experiment.  There were four treatments and four replications used in this experiment.  The treatments consisted of R0= control ration, R1= cube CFB, R2= cylinder CFB and R3= ball CFB.  The treatment feeds were fed twice a day, at 6.00 am and 15.00 pm.  The amount of morning ration 34 kg of fresh napier grass and 5 kg of concentrate for the control ration, and the same amount of ration was also given in the afternoon feeding, therefore, the daily total fresh forage was 68 kg and concentrate was 10 kg.  Before feeding the forage was chopped in 5 cm length.  The complete feed block for the dairy cows was 10 kg for the morning ration and 10 kg for the afternoon ration, therefore, the daily total complete feed block was 20 kg.  The drinking water was available adlibitum.  The preliminary period was conducted for 2 weeks and data collection were conducted for 5 day of the end of study. The variables measured were dry matter and organic matter intake, dry matter digestibility and milk production.  These results showed that the control ration significantly affected with  ration all CFB form on dry matter and organic matter intake but did not significantly affect the dry matter digestibility and milk production. Key words : dairy cttle, complete feed block Abstrak.Penelitian ini bertujuan mengevaluasi pengaruh tiga pakan komplit bentuk cetak yaitu bentuk kubus, silinder dan bola yang diberikan pada sapi perah.   Pakan komplit bentuk cetak dibuat dari hijauan rumput gajah yang spesifik toleran tanah masam yang telah digiling dan bahan konsentrat dengan perbandingan 50:50.  Rancangan percobaan yang digunakan adalah rancangan acak kelompok.  Enam belas ekor sapi perah dikelompokkan menjadi 4 dengan 4 ulangan.  Empat perlakuan yang dicobakan yaitu R0= ransum kontrol, R1= pakan komplit cetak bentuk kubus, R2= pakan komplit cetak bentuk silinder, dan R3= pakan komplit cetak bentuk bola. Pakan perlakuan diberikan dua kali sehari pagi pukul 06.00 dan sore 15.00.  Jumlah pakan  yang diberikan pada sapi perah kontrol pagi sebanyak 34 kg rumput gajah segar dan 5 kg konsentrat demikian juga pemberian yang sama pada sore hari sehingga jumlah hijauan segar yang diberikan kepada ternak 68 kg dan konsentrat 10 kg.  Rumput gajah yang diberikan sudah dipotong-potong terlebih dahulu dengan panjang 5 cm.  Jumlah pakan komplit cetak untuk sapi perah perlakuan yang diberikan pagi jumlahnya sama dengan pemberian sore masing-masing sebanyak 10 kg sehingga jumlah pakan komplit cetak yang diberikan 20 kg.  Air minum diberikan adlibitum.  Periode preliminary dilakukan selama 2 minggu dan koleksi data dilakukan selama 5 hari periode akhir percobaan.  Variabel yang diamati adalah konsumsi bahan kering dan bahan organik pakan, kecernaan bahan kering pakan dan produksi susu.  Hasil penelitian menunjukkan bahwa ransum kontrol beda nyata dengan semua bentuk pakan komplit cetak pada konsumsi bahan kering dan bahan organik, akan tetapi tidak berbeda nyata dengan  kecernaan bahan kering dan produksi susu. Kata kunci : sapi perah, pakan komplit bentuk cetak

The Use of Pacific Menhaden Oil and Palm Oil on Lipid Metabolism Profile in Blood Serum of Native Cockerels

Cholesterol is an important component of cell membrane, plasma lipoprotein and precursor of steroid synthesis in biologically crucial bile salt and steroid hormones.  Cholesterol level in the blood exceeding the 300 mg/100 ml can result in the incident of cardiac disorder. Cholesterol, HDL (High Density of Lipoprotein), LDL (Low Density of Lipo protein) biosynthesis in the blood plasma of broiler chicken can be manipulated by the use of Pacific Menhaden Oil and Palm Oil.  Therefore, The aim of the current experiment was to investigate the effect of  long chain fatty acid from Pacific Menhaden Oil (PMO) and Palm Oil (PO) use in feed on the blood level of cholesterol, HDL and LDL of native cockerels. Four kinds of ration which contained different levels of PMO and PO were formulated.  They were R0 (control, without PMO and PO); R1 (10% PO); R2  (10% PMO) and R3 (5% PMO and 5% PO).  A total of 72 native cockerels, aged two weeks were kept in 24 pens, three cockerels in each pen.  Each experimental unit were assingned at random to receive one of the four rations in completely randomized designed with six replicates. The use of PMO and PO in feed did not significantly affect (P>0.05) the concentration of cholesterol, HDL, LDL and triglyceride in the blood.  Although statistically was not significantly significant, Cockerels fed R2 had the highest concentration of HDL (39.36 mg/dl) and the lowest concentration of LDL (9.10) in the blood.

Essential – Mineral Balance on Growing Male Cattle

An experiment was designed to study the effect of unconventional protein source on the essential minerals balances of growing cattle.  The experiment had been conducted by experimental method with Completely Randomized Block Design, on twelve growing male cattle of Ongole Grade.  Based on the body weight, the animal trial was separated to three blocks, as the replication.  The tested treatment was four kind of protein sources in the ration (R):  R1 = kapok – seeds cakes; R2 = lamtoro – leave meals; R3 = cacao – pod meals and R4 = goat’s faeces.  The compose of ration was 50 percent of Elephant grass and 50 percent of concentrate (DM basis).  The measured variables were: the essential mineral balances i.e. Calcium, Phosphorus, Sodium, Potasium, Chlorine, Magnesium, Sulphur and Nitrogen.  The balance – trial was conducted by the total collection method.  The data was analyzed by the analysis of variance, and that of the interaction (Synergistic and antagonistic) by the Regression Analysis.  The result indicated that the total of essential mineral balance of each protein source or each ration on growing cattle of Ongole Grade is:  Cacao – pod meals = 116.09 g/day; Goat’s faeces = 111.89 g/day; lamtoro – leave meal = 84.64 g/day and Kapok – seed cake = 78.55 g/day.  These phenomena shown that all of the animal trial was in normal growth.  The strong synergistic interaction was reached by Ca « P (P <0.01; R2 = 0.92 – 0.98) while the weak interaction by Na « Cl (P > 0.05; R2 = 0.03 – 0.05).  Among the five couples of mineral elements of the antagonistic interaction the strong interaction was N ® S (P < 0.01; R2 = 0.70 – 0.75), while the weak interaction was Na ® P (P > 0.05; R2 = 0.08).  Based on all the variables measured, the experiment is concluded that: (1) all of the unconventional protein sources are able to improve the quality of the ration, indicated by the positive essential mineral balance on growing cattle of Ongole grade; (2) based on the total essential mineral balance, the most suitable protein source for growing cattle is cacao – pod meals; (3) the strong synergistic interaction was reached by Ca <----> P, while the antagonistic interaction was N ----> S.  (Animal Production 6(2): 101-109 (2004) Key Words: mineral, protein source, Ongole, cattle

The Effect of Debeaking and Crude Fibre in Ration On Canibalism and Performance of Muscovy Duck

A research has been conducted from September 3rd until November 2nd 2002 to study cannibalism and performance of Muscovy duck. The method applied was experiment with factorial pattern of Completely Randomized Design (CRD). The first factors were debeaking (P) : p1 = control, p2 = debeaking. The second factors were crude fibre content in ration (R) : r1= 6 %, r2 = 8 % and r3 = 10 %.  Parameters observed were cannibalism mortality, food consumption, growth rate, carcass production, meat and blood cholesterol and meat fat. The duck used were 96 heads at one week old and cage in 24 pens with litter floor.  The results indicated that debeaking had no significant effect on food consumption, growth rate, carcass percentage and blood cholesterol, but it had significant effect on carcass weight and meat fat up to 8 weeks old. Crude fibre had significant effect on blood and meat cholesterol. (Animal Production 6(1): 9-16 (2004) Key Words: Debeaking, Crude fibre, Canibalism, Production Performance
