Ninety six commercial strain were conducted from 14 to 42 days of age to evaluate the affect of utilization zeolite and on performance of broiler and fecal characteristics. Birds were divided into four  treatment diets (4 replicates of 7 birds each): K (control), KB (K+ 1% bentonite),  KZ (K+ 1% zeolite), KBZ (K+ 1% Z+ 1% B). The birds were fed initially for two weeks a commercial starter ration and followed by treatment  diets 15 to 42 days of age. All the diets were formulated to have 20% crude protein and 3000 kcal. ME and 0.91% Ca and 0.69% P for control and 0.34% treatments. Body weights and feed intakes were measured on a weekly basis. The manure from each group was sampled on weekly basis and the  moisture content, pH and ammonia production was determined. The results showed the utilization zeolite and bentonite or both significant differences (P<0.05) on pH and (P<0.01) fecal ammonia content, but not on feces water content, final body weight, feed consumption, feed conversion ratio, and carcass.

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 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.

The research attempted to find out ratio of native grass and concentrate in the ration to the quality of milk production of Holstein cow. Latin Square Design was used with five treatments of ratio of native grass and concentrate ( 70 : 30%, 60 : 40%, 50 : 50%, 40 : 60%, 30 : 70%), applied using five Holstein cows at the third lactation periode and the third mounth of lactation. The variable measured were in the quality milk production consist of actual milk yield, the milk fat content, crude protein, solid non fat, efficiency of  energy bruto and energy netto, and income over feed cost. The best ratio of native grass and concentrate in the ration for the efficiency of energy bruto, energy netto and income was 50 : 50%. The milk fat content and actual milk yield have relationship form with the milk energy value. The best ratio of native grass and concentrate in the ration to increasing the milk fat content, crude protein and crude of solid non fat was 70 : 30%.
