ABSTRACT   The purpose of this research was to know the relationship between the the weight and body measurements at age of 12 weeks  of crossbreds of three chicken types that were broiler, kate and Sabu chicken. The relationship of body weight with the body measurements  was used as a consideration for selecting the body weight.  The research  material  was 30 tails of  crossbreds  with genotype composition was ½ broiler 1/4  Kate ¼ Sabu chicken.  The method of research was experiment and directly weighting and measuring of the body measuremens. All  chickens  were given freely the  same  food  and waters. The observed parameters were body  weight, backbone  length, chest circumference, shank circumference and wing span.  Data   was analised using the correlation analysis.  Research results  obtained  the koefisien of correlation between  chest circumference, backbone length,  shank length  and wing span  with body weight were 0.62; 0.32; 031 and 0.20.  Correlations between body weight  and  body measurements  of chicken crossbreds   with genotype composision ½ broiler  ¼ Kate ¼ Sabu   were positip.

There are various types of native chickens in Nusa Tenggara Timur Indonesia that have the opportunity to be developed such as Sabu chicken, Semau chicken, and also KUB chicken. So that the selection of seeds from these chickens can be done earlier, it is necessary to know the magnitude of the correlation value between various ages of growth, so that the selection can be done earlier. The purpose of this study was to analyze the correlation of several growth traits of three genetic groups of native chickens, namely Sabu chickens, Semau chickens, and KUB chickens that were reared intensively from 0-8 weeks of age. This study used a completely randomized design. All correlation data were analyzed using Pearson Correlation, using SPSS Release 21. The results showed that there was a high positive correlation value between DOC weight and body weight at 8 weeks of age, so that DOC weight could be used as a selection basis for body weight 8 weeks old.

The aims of this research  were to  estimate   repitability  coefficients of production  at birth  and  weaning characters  and to determine the average and standard deviation  of landrace  crossbreed sows. This research  was carried out in two breeding farms namely the Instalation of Pig Breeding, village of Tarus, Kupang Regency and the Manise Pig Farm, Village of Oetete, Kupang City, East  Nusa  Tenggara.   Materials used  15heads  landrace  crossbreed  sows ( 15  heads ) which born and weaned piglets  during the study periode.  The number of piglets for the first parity was 151heads and for the second parity was  162heads. All  sows  was  mated by artivicial insemination  with  boars of  landrace  crossbreed.   Variables were  liter size, weaning rate, birth weight, weaning  weight and weaning  rate.  Results  showed that landrace  crossbreed sows had the  average and  deviation standard for  the first and second liter size were 10.00±1.50heads  and  10.73±2.40heads, respectively;  for the first and second  birth weight were 1.37±0.23kg and 1.68±0.34kg, respectively;  for the first and second weaning  weight were  6.42±0.38kg  and  6.72±0.51kg, respectively  and for the first and second weaning rate were 8.33±1.28heads and  8.68±1.43 heads; respectively.  The average of litter size, birth weight, weaning weight and weaning rate between the first and second  parity  was no difference (P > 0,05). The  value of  repeatabitily for  characters  of  liter size, birth weight, weaning weight  and  weaning  rate   were  0.32; 0.47;  0.49 and 0,42; respectively.   In  conclusion,  the   repeatabily value   of litter  size,  birth weight, weaning  weight and weaning rate from landrace  crossbred sows were  medium value  and the performance of  those characters between  the first  and  second parity were  no difference.

Penelitian ini bertujuan untuk mengetahui kinerja produksi sapi bali pengemukan yang diberi pakan komplit berbasis silase batang pisang dengan level berbeda. Ternak yang digunakan dalam penelitian ini adalah 12 ekor sapi bali jantan penggemukan dengan kisaran berat badan 80,5-97 kg dengan rataan 89,4 kg KV = 10,07 %. Metode penelitian yang digunakan adalah metode percobaan menggunakan rancangan acak lengkap (RAL) dengan 4 perlakuan dan 3 ulangan.  Perlakuannya di dalam penelitian ini yaitu R0: silase batang pisang 80% + konsentrat 20%, R1: silase batang pisang 70% + konsentrat 30%, R2: silase batang pisang 60% + konsentrat 40% dan R3: silase batang pisang 50% + konsentrat 50%. Hasil analisis statistik menunjukkan bahwa perlakuan berpengaruh nyata (P<0,05) terhadap pertambahan berat badan harian sapi bali penggemukan dan berpengaruh tidak nyata (P>0,05) terhadap nilai konversi ransum dan efisiensi ransum. Kesimpuan pemberian pakan komplit berbasis silase batang pisang 50% dan konsentrat 50% menghasilkan pertambahan bobot badan harian sebesar 0,47 kg/e/h. Kata kunci: kinerja produksi, pakan komplit, silase batang pisang, sapi Bali   This study aims to determine the production performance of fattening bali cattle fed complete feed based on banana stem silage with different levels. The livestock used in this study were 12 fattening male bali cattle with a body weight range of 80.5-97 kg with an average of 89.4 kg KV = 10.07%. The research method used is an experimental method using a completely randomized design (CRD) with 4 treatments and 3 replications. The treatments in this study were R0: banana stem silage 80% + concentrate 20%, R1: banana stem silage 70% + concentrate 30%, R2: banana stem silage 60% + concentrate 40% and R3: banana stem silage 50% + 50% concentrate. The results of statistical analysis showed that the treatment had a significant (P<0.05) effect on daily weight gain of fattening bali cattle and an insignificant (P>0.05) effect on the ration conversion value and ration efficiency. The conclusion of giving complete feed based on 50% banana stem silage and 50% concentrate resulted in daily body weight gain of 0.47 kg/e/h.

This aim of the research was to know the influence of sex on production performances at birth age of piglets of   duroc sow crossbreds. The research was carried out in two breeding farms namely the Instalation of Pig Breeding, village of Tarus, Kupang Regency and the Manise Pig Farm, Village of Oetete, Kupang City, East  Nusa  Tenggara (NTT).  There were 20 heads of duroc  crossbred sows. The method  used a survey and samples were collected purposively. Samples were all pigles  that  born  during  research period from  all of duroc sow crossbreds. The variables were litter size, body weight, girth size, and body length. Data was differentiated between males and females  and analysed using the t test.  The results showed that  males had  the average of litter size, body weight, girth size and body length of  4.94±1.21 head; 1.42±0.55kg; 23.94±2.80cm  and 21.91±4.06cm, respectively;  while  females had the average of liter size, body weight, girth size and body length of 4.60±1.32 head; 1.39±0.38kg; 23.20±2.76cm and 20.93±4.20cm,  respectively. Statistical analysis showed that there was no difference (P>0.05) between males and females from observation variables. Performances of piglets from duroc sow crossbreds for male and female characters such as litter size, birth weight, girth size and body length were relatively similar.
