Abstract

Growth curves can be used to reflect changes in the body structure due to genetic and environmental responses. Here, six growth curve models are used: Gompertz, Logistic, Richard, Von Bertalanffy, Morgan-Mercer-Flodin (MMF), and Weibull models. This study aims to determine patterns and growth as seen from changes in ages and weights of male and female Garut sheep at UPTD-BPPTDK Margawati Garut. The case study method was used with 214 samples. Data from samples were processed to find similarities and curve shapes and the data was examined using Curve Expert software. The results showed that each parameter measured has a sigmoid growth curve. The curve model with the best accuracy to determine the growth rate of Garut sheep at UPTD-BPPTDK Margawati Garut is the Gompertz model, with correlation values for single birth type: average determination coefficient of 0.99, standard error of 0.98, and 0.82. For twin birth type, the average coefficient of determination is 0.99, standard errors are 0.63 and 0.57. For triplet birth type, the average coefficient of determination is 0.99, standard errors are 0.46 and 0.65.

Abstract

The study investigating the relationship between body weight and egg weight in Padjadjaran quails, encompassing both layer and broiler types, was conducted at the Quail Breeding Center within the Faculty of Animal Husbandry at Universitas Padjadjaran. The research involved 100 female quails, consisting of 50 from each type, all of which were 15 weeks old, along with their eggs. The primary aim was to assess the strength and nature of the relationship between body weight and egg weight in these quails. A correlational method was employed for the analysis. The findings revealed a strong correlation between body weight and egg weight in Padjadjaran layer quails, indicated by a correlation coefficient of 0.792. The relationship was represented by the regression equation \( y = 0.0586x + 0.8429 \), which had a relatively high coefficient of determination (\( R^2 \)) of 0.6281. Conversely, the results for Padjadjaran broiler quails indicated a weak correlation, with a correlation coefficient of 0.374. The regression equation for broiler quails was \( y = 0.0145x + 8.0157 \), exhibiting a low coefficient of determination (\( R^2 \)) of 0.1402. In conclusion, the study identified a strong correlation between body weight and egg weight for Padjadjaran layer quails, while a weak correlation was observed for Padjadjaran broiler quails. Furthermore, the regression equation for predicting egg weight based on body weight is deemed reliable for Padjadjaran layer quails but not applicable to broiler quails, as the low determination value suggests that the regression model for broiler quails is insufficient for such predictions.

Abstract

The purpose of this study was to determine the performance and repeatability values of S/C, DO, and CI in the South Garut Farmers Cooperative. Reproduction data used were individual reproduction records of 162 Friesian Holstein dairy cows. The results showed that the average reproductive performance for S/C for parity 1 was 2.20 ± 0.797, parity 2 was 2.40 ± 0.974, parity 3 was 2.28 ± 0.947, parity 4 was 2.22 ± 0.965, and the total value of S/C was 2.28 ± 0.921. The DO value for parity 1 was 159.50 ± 80.838, parity 2 was 150.43 ± 73.874, parity 3 was 142.29 ± 56.689 days, parity 4 was 133.79 ± 42.678 days, and the total DO was 146, 50 ± 67.267 days. The CI value for parity 1 was 437.91 ± 80.144 days, parity 2 was 430.20 ± 75.211 days, parity 3 was 423.31 ± 57 days, parity 4 was 414.59 ± 42.470 days, and the total CI was 426, 5 ± 67.355 days. The repeatability value at KPGS for S/C was 0.17 ± 0.033, DO was 0.1 ± 0.040, and CI was 0.097 ± 0.040. These three reproductive properties show repeatability values in the low category

Abstract

Kondisi sebaran rumpun dan pola warna bulu pada suatu wilayah di beberapa pasar hewan relatif seragam.  Hal tersebut cenderung dipengaruhi oleh faktor wilayah dan preferensi peternak di wilayah tersebut.  Penelitian ini bertujuan untuk mengidentifikasi sebaran rumpun dan pola warna bulu domba lokal jantan di Kabupaten Purwakarta.  Objek penelitian ini adalah seluruh domba lokal jantan yang ada di pasar hewan Kabupaten Purwakarta.  Metode penelitian yang digunakan adalah deskriptif analitik, dengan melakukan sensus di Pasar Hewan Wanayasa, Bojong, dan Plered.  Berdasarkan hasil penelitian yang dilakukan, sebaran rumpun domba lokal jantan yang tersebar di tiga pasar hewan yaitu  Domba Garut sejumlah  24,1%, Domba Priangan sejumlah  75,2%, dan Domba Ekor Tipis sejumlah  0,7%.  Pola warna bulu domba lokal jantan yang tersebar adalah dominan putih sejumlah 85,3%, dominan hitam sejumlah 6,5%, dominan coklat sejumlah 2,3%, dan warna kombinasi sejumlah 5,9%.  Berdasarkan hasil pengamatan di lapangan, domba yang dominan di beberapa pasar hewan yang ada Kabupaten Purwakarta adalah Domba Priangan dengan pola warna bulu putih.Kata Kunci : Rumpun, Pola Warna Bulu, Domba Lokal Jantan, Pasar Hewan

Abstract

Brahman Indonesia cattle are a superior beef breed developed in Indonesia to increase national productivity, but their performance is influenced by various non-genetic factors. This study aimed to analyze the effect of these factors, specifically calf sex and dam parity, on the body weight performance of Brahman Indonesia cattle at BPTU-HPT Sembawa. Data from 2014-2023, consisting of 5,213 records (2,115 birth weight, 1,672 weaning weight, and 1,426 yearling weight) from the progeny of 31 sires and 178 dams, were analyzed using the General Linear Model (GLM) and Duncan's Multiple Range Test. The results showed that both calf sex and dam parity had a very significant effect (P<0.0001) on all observed growth traits. Male calves were consistently heavier than female calves at all age stages, while dam parity exhibited a performance pattern that was lowest at the first parity and reached its peak at parities 3-6. These findings confirm the importance of correcting for non-genetic factors in selection programs to improve the accuracy of genetic evaluation for Brahman Indonesia cattle breeding stock.

Abstract

Sentul chicken is a local from Ciamis Regency that has potential as an alternative source of animal protein. The utilization of microencapsulated noni fruit extract products that are rich in bioactive compounds in the ration is expected to improve the quality of meat through improving the nutritional composition of the ration. This study was using 100 Sentul chickens divided into four treatment groups, where the rations were given with variations in the addition of microencapsulated products at doses of 0, 75, 150, and 225 mg/kg MNFE. The microencapsulation method was carried out by coating noni extract using maltodextrin and drying it using the spray drying method. The results showed that microencapsulation of noni fruit extract had a significant effect on carcass weight, cholesterol content, and fat content of chicken meat. The optimal doses was found at 75-150 mg/kg MNFE which resulted in an increase in carcass weight and a decrease in cholesterol levels and the most effective meat fat. Therefore, using of microencapsulated noni fruit extract not only improves meat quality, but can also be an alternative solution in the livestock industry, especially in reducing the use of Antibiotic Growth Promoter (AGP) and increasing poultry meat quality.
