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

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.

Abstract

Kurva produksi susu merupakan kurva yang dapat menggambarkan jumlah susu yang dihasilkan oleh sapi perah selama siklus laktasinya. Model kurva yang memiliki tingkat akurasi tinggi antara produksi susu aktual dan pendugaan adalah model kurva Wood dan juga model kurva Ali-Schaeffer. Penelitian ini menganalisis produksi susu di PT. Sumber Citarasa Alam selama periode laktasi pertama dan kedua serta membandingkan akurasi model kurva Wood dan model Ali-Schaeffer dalam merepresentasikan data produksi susu. Standard error (Se) dan koefisien korelasi (r) digunakan sebagai indikator akurasi dalam evaluasi. Hasil penelitian menunjukkan bahwa puncak produksi susu terjadi lebih awal pada periode laktasi kedua dibandingkan dengan periode pertama, yakni pada minggu ke-5 untuk periode kedua dan minggu ke-6 untuk periode pertama. Rata-rata produksi susu pada periode laktasi pertama lebih rendah (13,33 liter) dibandingkan dengan periode laktasi kedua (14,83 liter), setelah itu kurva produksi mengalami penurunan yang berfluktuasi hingga akhir masa laktasi. Model Ali-Schaeffer memberikan pendugaan produksi susu yang lebih akurat pada kedua periode dibandingkan dengan model kurva Wood. Selain itu, nilai Se (0,891 dan 0,955) serta nilai r (0,395 dan 0,429) menunjukkan bahwa model kurva Ali-Schaeffer memiliki korelasi yang lebih kuat dan akurasi yang lebih tinggi dalam merepresentasikan data produksi susu di PT. Sumber Citarasa Alam. ABSTRACT The milk production curve is a model that illustrates the amount of milk produced by dairy cows throughout their lactation cycle. Curve models that exhibit high accuracy between actual milk yield and estimation include the Wood curve model and the Ali-Schaeffer curve model. This study aimed to analyze the milk production of dairy cows at PT. Sumber Citarasa Alam during lactation periods 1 and 2, and to determine which equation between the Wood curve model and the Ali-Schaeffer model most accurately represented the company’s dairy production data. The models were evaluated using Standard Error (SE) and correlation coefficient (r) as accuracy indicators. The study results indicated that dairy cow milk production at PT. Sumber Citarasa Alam reached peak production faster in the second lactation period compared to the first. Peak production occurred in the fifth week for lactation period 2, whereas it occurred in the sixth week for lactation period 1. The average milk production in the first lactation period was lower, amounting to 13.33 liters, while the second lactation period reached 14.83 liters. The production curve then declined fluctuatively until the end of lactation. The Ali-Schaeffer milk production curve model demonstrated a higher estimation accuracy for actual milk production in both lactation periods compared to the Wood curve model. Furthermore, based on the obtained SE values (0.891 and 0.955) and correlation coefficients (0.395 and 0.429), the Ali-Schaeffer model exhibited high correlation and accuracy.
