Abstract

Crossbreeding is carried out with the aim of enhancing and combining favorable traits between different breeds. The results of crossbreeding can be analyzed through genetic distance measured by various parameters, including morphometric measurements of livestock bodies. This study aims to analyze the morphometric diversity based on body measurements and canonical analysis in PE, Saanen, and Sapera goats to determine their genetic proximity. The research utilized a quantitative descriptive method using primary and secondary data from the BALITNAK Ciawi dairy goat station through a canonical analysis approach. The study and collection of primary and secondary data were conducted from March to April 2022. The research was carried out at the BALITNAK Dairy Goat Research Station in Ciawi Subdistrict, Bogor Regency. The results of this study indicate that the genetic distance between Sapera and Saanen goats is closer than between Sapera and PE goats. Furthermore, in terms of body measurements, the measurements of Sapera goats are closer to the Saanen goats compared to the PE goats. It can be concluded that the body size of Sapera goats is more similar to that of PE goats, while their external appearance is closer to the Saanen goats, which have predominantly white fur color.

Abstract

Developing Bali cattle population in Timor Island, East Nusa Tenggara province carries a potential issue regarding cattle population. The objective of this research was to conduct an analysis and projection of the development of Bali cattle population in the agricultural ecosystem in Timor Island using system dynamics. The research was conducted from January to September 2018. The research location was determined purposively based on the characteristics of the agricultural ecosystem located in Kupang Regency and Kupang City. The research used 60 Bali cattle and involved 102 rancher respondents. Interviews and field observations were conducted to obtain primary and secondary data. Data analysis was done by building a system dynamics using Powersim and interpreting the simulation results for the next 30 years. The analysis results of the system dynamics showed that a declining population of Bali cattle over the next 19 or 25 years due to the ranchers' current behavior. The contributing factors included calf mortality that reached 29.6% per year; Bali cow mortality was up to 14.1% per year; calving interval was 22 months; traditional farm management that it is not economical; and the rate of livestock export reached 29.5% per year of the total population. Rancher management interventions and farm policies to reduce the inhibiting factors of cattle productivity are needed to maintain the population of Bali cattle in Timor Island, especially in the agricultural ecosystem.

ABSTRACT. Penelitian ini bertujuan untuk mengevaluasi pengaruh substitusi hijauan dengan silase daun ubi kayu (SDUK) dan konsentrat dengan hay ubi kayu difermentasi ragi (Habira) terhadap produksi susu, kualitas susu, dan efisiensi ekonomi sapi perah. Materi yang digunakan adalah lima (5) ekor sapi Friesian Holstein (FH) periode laktasi kedua (6611 hari) dengan bobot badan 387,66,8 kg diberi perlakuan pakan dalam Rancangan Bujur Sangkar Latin 5 x 5. Perlakuannya adalah T0 (hijauan 60% + 20% konsentrat + 20% ampas tahu), T1 (hijauan 40% + 20% SDUK + 20% konsentrat + 20% ampas tahu), T2 (hijauan 40% + 20% SDUK + 15%. konsentrat + 20% ampas tahu + 5% Habira), T3 (40% hijauan + 20% SDUK + 15% konsentrat + 20% ampas tahu + 10% Habira) dan T4 (60% hijauan + 10% konsentrat + 20% limbah tahu + 10% Habira). Variabel yang diukur adalah indeks suhu kelembapan (THI), konsumsi pakan, produksi susu, kualitas susu, hubungan konsumsi protein dan total nutrien tercerna/total digestible nutrient (TDN) dengan produksi susu serta efisiensi pakan dan ekonomi. Hasil penelitian menunjukkan bahwa nilai THI yang diperoleh mengindikasikan sapi perah mengalami cekaman panas. Perlakuan T1, T2, T3 dan T4 berbeda nyata (P0,05) dengan T0 dalam konsumsi nutrisi dan produksi susu, sedangkan komposisi susu tidak berbeda nyata antar perlakuan. Konsumsi protein dan TDN pakan memiliki hubungan linier dengan produksi susu (P0,05). Tidak ada perbedaan signifikan (P0,05) dalam efisiensi pakan dan ekonomis. Dapat disimpulkan SDUK dan Habira merupakan pengganti hijauan dan konsentrat yang baik untuk sapi perah laktasi.(Effect of forage and concentrate substitution with cassava leaves silage and cassava hay on milk production and milk composition of Friesian Holstein dairy cows)ABSTRAK. This study aimed to evaluate the effect of forage replacement by cassava leaves silage (CLS) and commercial concentrate by yeast fermented cassava hay (Yefecah) on the production and quality of milk and economic evaluation. Five, early on the second lactation cycle (6611 day in milk) Holstein Friesian cows were randomly assigned to a 5 (treatments) x 5 (replications). Treatments were T0 (60% forage + 20% concentrate + 20% tofu waste), T1 (40% forage + 20% CLS + 20 % concentrate + 20% tofu waste), T2 (40% forage + 20 % CLS + 15% concentrate + 20% tofu waste + 5% Yefecah), T3 (40% forage + 20 % CLS + 15% concentrate + 20% tofu waste + 10% Yefecah) and T4 (60% forage + 10% concentrate + 20% tofu waste + 10% Yefecah). Variables measured were temperature-humidity index (THI), feed intake, milk production, milk composition, interrelationship crude protein (CP) and total digestible nutrient (TDN) supply to milk production, and economic factors. The Result shows that T1, T2, T3, and T4 were significantly (P0.05) from T0 on nutrients intake and milk production. Whilst, the treatments were not significant (P0.05) affect to 4% fat corrected milk (FCM) and milk quality with T2 and T3 obtained the best value. The variables of CP and TDN intake have a positive relationship to milk production (P0.05). There were no significant differences in (P0.05) in feed and economical efficiency. It could be concluded that cassava foliage silage and yefecah were the good replacement of forage and concentrate for dairy cows.

Abstract

The accumulation of ammonia in excreta waste cause air pollution and health problems for both humans and livestock. A solution to address this issue is through the bioconversion process using Black Soldier Fly larvae (BSFL). This study aims to evaluate the feasibility of Black Soldier Fly Larvae (BSFL) production using quail excreta as a growth medium and to analyze biomass production (BSFL and BSFL Frass) because of bioconversion. This study used a Randomized Block Design consisting of 2 treatments: non-fermented quail excreta (P0) and fermented quail excreta (P1). The bioconversion process was carried out at 3 different time periods. The variables observed are bioconversion indicators: growth rate, conversion efficiency (ECI), the weight of the BSFL, the weight and the characteristics of the BFSL frass. The data were analyzed using analysis of variance (ANOVA), followed by the Least Significant Difference (LSD) test. The average growth rate of BSFL P0 (10.97%) and P1 (12.52%) was not significantly different, in line with the conversion efficiency (ECI) value in the P0 treatment (0.08) and P1 treatment (0.11). The bioconversion results showed that the production of BSFL in non-fermented quail excreta media reached 10.97% ± 6.74%, while in fermented excreta media it reached 12.52% ± 1.98%. This study indicates that quail excreta have the potential as a medium for BSFL production, and the excreta fermentation process does not have a significant effect on the bioconversion process based on bioconversion indicator variables.
