Abstract

Rice straw (RS) is widely available in South East Asia and it can be used as a source of fibres for ruminant animals. However, RS has poor palatability and nutritional values. Thus, the use of concentrate (CON) as a dietary supplement is required to increase the utilisation of RS. Green (GT) and black (BT) teas can act as natural dietary additives in a CON. This study evaluated nutrient compositions of the diet ingredients and the impact of supplementing GT and BT in a rice straw-based sheep diet on in vitro dry matter degradability (IVDMD), total gas production (TGP) and  pH during more than 24 hours of incubations. The CON, GT, and BT had higher crude protein, organic matter, and metabolizable energy but lower fibre fractions than RS. The GT and BT had greater total tannins than CON and RS confirming that they could potentially be used as natural dietary additives. In addition, GT supplementation improved IVDMD without affecting TGP and pH values. Conversely, BT supplementation did not improved IVDMD. Thus, BT is less preferable as a ruminant dietary supplement than GT.

Abstract

Gender equality is an increasingly relevant issue for developing countries, including Indonesia. However, recognition of women's contribution to the livestock sector still needs to improve, which can affect their motivation to be more actively involved in the livestock business. The Foot and Mouth Disease (FMD) pandemic has become an additional challenge by causing a decrease in income from livestock activities. This research aims to examine the division of women's roles, analyze the impact of household characteristics on gender equality, and evaluate the level of gender integration among post-FMD livestock farmers. The research method used was simple random sampling and multinomial logit regression analysis. The research results show a change in the role of women who are more active in diversifying sources of income, as well as the influence of household characteristics on gender equality in access to economic opportunities. In addition, the level of gender integration among farmers after the FMD has shown a responsive level of 56% and a transformative level of 44%, reflecting positive developments in gender practices and awareness in the livestock sector.

Abstract

This research examined the effect of different densities on carcass weight, carcass parts, and carcass percentage. The material used in this research was 200 broiler chickens aged three weeks, reared for 14 days until they were 35 days old. The experimental design used was a Completely Randomized Design (CRD) consisting of 5 treatments and four replications. If the analysis of variance showed an effect of treatment (P<0,05), then Duncan's Multiple Range Test was carried out to determine the effect between treatments. The treatments used were P1 = density of 13 birds/m², P2 = density of 14 birds/m², P3 = density of 15 birds/m², P4 = density of 16 birds/m², and P5 = density of 17 birds/m². The study found that density had no significant effect (P>0,05) on the carcass weight, carcass parts, and carcass percentage. Based on the research results, it can be concluded that a density of 16 birds/m² for broiler chickens kept in closed houses still provides good production performance and meat quality.

Abstract

Madura bull are one of the local bulls in Indonesia whose semen is used for artificial insemination. This study aims to evaluate the quality of semen and the repeatability value of semen from Madura bulls at the Lembang Artificial Insemination Center. A total of 1,402 semen collection data from three Madura bulls from 2014-2020 were used for analysis. The data was analyzed descriptively to evaluate semen quality consisting of semen volume, sperm motility and sperm concentration. Repeatability value was estimated using analysis of variance and intra-class correlation. The results showed that the average volume, motility, and concentration were 5.32 ± 1.50 ml; 68.10±7.07 %; and 1,044.27 ± 277.63 million/ml. The semen volume repeatability value was high, motility was low, and concentration was medium.

Abstract

Indonesia is a tropical country with high ambient temperatures and humidity. In Indonesia’s hot and humid summer, dairy cows cannot dissipate enough body heat to prevent a rise in their body temperature. Increasing air temperature, temperature humidity index, and rectal temperature above a critical threshold are associated with decreased dry matter intake (DMI), milk production, and milk production efficiency. Modifications including shades and cooling fans can help dissipate body heat, lower body temperature, and increase BMI. Genetic selection for heat tolerance is possible, but continued selection for better performance without consideration for heat tolerance will result in greater susceptibility to heat stress. The nutritional requirements of dairy cows change during heat stress, and ration reformulation to account for reduced DMI, the need to increase nutrient density, alter nutrient requirements, avoid excess nutrients and maintain normal rumen function is required. Sustaining cattle performance in hot and humid climate conditions in the future will likely require increased cooling capabilities, continued advances in nutritional formulations, and the need for genetic advances that include selection for heat tolerance or identification of genetic traits that enhance heat tolerance.

Abstract

The research explored the use of boiled sunflower seed meal (BSSM) as sustainable feed alternative for broiler chickens, evaluating its impact on their growth and development thereby reducing the industry’s reliance on resource-intensive feed ingredients. One hundred and fifty unsexed Ross broiler chicks were used for the study. The experiment was laid in a completely randomized design (CRD) in which BSSM were incorporated in the diets at 0, 10, 20, 30 and 40%, coded as Treatments 1, 2, 3, 4, and 5, respectively. Each treatment comprised of 3 replicates of 10 birds. Birds were housed in floor pens containing wood shavings as litter material. The diets and fresh drinking water were provided ad libitum throughout the eight weeks of the experiment. Data were analysed in statistical analysis system (SAS) package. Results revealed significant differences (p<0.05) in all the growth parameters measured except for initial body weight, feed conversion ratio and mortality. The packed cells volume (PVC) and white blood cells (WBC) were affected (p<0.05) by the treatment effect. Broiler chickens' health and productivity were not negatively affected by 30-40% BSSM inclusion in their diets, suggesting further research on improving sunflower seed using alternative treatment options.

Abstract

This study aimed to find out what happened to the performance of Sentul chickens when microencapsulated noni fruit (Morinda citrifolia Linn.) extract was added to their food during the production phase. The research employed a sample of 40 Sentul hens aged 24 weeks and spanned 12 weeks. The investigation used a completely randomized design (CRD) and an experimental method. The treatments comprised five distinct types: P0 (basal diet), P1 (basal diet supplemented with 50 mg/kg zinc bacitracin), P2 (basal diet supplemented with 75 mg/kg MEBM), P3 (basal diet supplemented with 150 mg/kg MEBM), and P4 (basal diet supplemented with 225 mg/kg MEBM). The study's findings indicate that the P4 treatment statistically impacted the mean egg weight. Similarly, the P3 treatment also significantly influenced hen day production and feed conversion ratio (FCR layer) but did not appear to affect feed consumption. Ultimately, adding microencapsulated noni fruit extract to the diet at 150 mg/kg MEBM and 225 mg/kg MEBM concentrations can raise the average egg weight, the number of days that hens lay eggs, and the feed conversion ratio.

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

A research was conducted to generate a mathematical model for estimating the rearing cost of replacement dairy cattle. This research uses a survey method to collect data regarding farmer expenditures in raising young dairy cattle. Data collection involved 67 farmer who kept 231 replacement dairy cows with various ages, from birth up to two years of age. Data analysis used linear regression to estimate an equation model for describe a causal relationship between the partial total cost (TCp) with the period of rearing the cattle (q). The analysis performs two model equation namely quadratic and cubic cost function. The second model performs a goodness of fit better, with an S-shaped curve, .  Analysis of variance result in the R2 of 0.67. Based on the estimated cost equation model above, total cash expenditure for two-year-old pregnant heifers reached IDR 15,565,800. If the opportunity cost of a calf is included in the cost calculation, the cost will increase to IDR 19,102,800. Compared to the local price for two-year-old heifers, farmers still have a price margin of IDR 6,211,200.Keywords: replacement cows, total cost partially, cost function

Abstract

Cow feces is the rest of the digestive process of the livestock body, while coffee grounds are the rest of coffee brewing, and both are organic materials with fixed carbon that can be utilized as fuel. The purpose of this study was to determine the effect of the addition of coffee grounds in processing dairy cow feces into briquettes on physical properties (color, texture, density), chemical properties (moisture content, ash content, volatile matter, and fixed carbon), and energy value (calorific value, temperature, flame duration). This research method is experimental, with four treatments, each consisting of five repetitions. The treatments in this study consisted of P1 (100 g dairy cow feces + 20 g coffee grounds), P2 (100 g dairy cow feces + 40 g coffee grounds), P3 (100 g dairy cow feces + 60 g coffee grounds), P4 (100 g dairy cow feces + 80 g coffee grounds). The data obtained were analyzed statistically with ANOVA at = 5%. Further tests were carried out using the Duncan test. The results showed that the addition of coffee grounds to dairy cow feces briquettes had a significant effect (p<0.05) on physical properties (density), chemical properties (moisture content, ash content, volatile substances, fixed carbon) and energy value (calorific value, temperature, and flame duration). The addition of 80 grams of coffee grounds (P4) gave the best effect on the performance of dairy cow feces briquettes with a moisture content of 6.94%, ash content of 25.47%, volatile matter of 18.58%, fixed carbon  of 49.02%, calorific value of 3717 cal/gr, temperature of 463°C.
