Abstract

The aim of this research was to determine the correlation between udder and body size of Saanen goats on milk production in BBPTU-HPT Baturraden. Total of 61 lactating Saanen goats were used in this study. The size of the udder was measured including the width and length of the udder, the inner and outer circusmference of the udder, the shape and volume of the udder, the length, circumference and direction of the nipple. Body measurements were measured including chest circumference, ear length and width, and body length and height. Body and udder characteristics were assessed once before milking while milk production was measured each milking. Data were analyzed using regression analysis. The correlation between body length, chest circumference, height, ear length, ear width, and neck wattle with milk production were 1.0%, 0.0%, 4.1%, 5.1%, 2.1 %, and 0.0% respectively. The correlation between udder volume, udder outer circumference, udder inner circumference, udder width, udder length, nipple circumference, and nipple length with milk production were 54.5%, 49.4%, 41.4%, 55.9,%, 10.9%, 24.2%, and 28.4% respectively. Saanen goat milk production had a correlation with udder characteristics but had no correlation with body size.

Abstract

In poultry, amino acids are sourced mainly from soybean meal (SBM). However, nutrient absorption and digestion are quickly reduced in the presence of antinutritional factors (ANFs), thus impairing poultry growth performance. Here, we experimented to determine the effects of fermented SBM with A. niger and B. subtilis on nutrient digestibility and carboxymethyl cellulase (CMCase) activity of Jawa Super (Joper) chicken. The experiment was completed from November 2022 to January 2023 on the poultry farm of the Animal Science Faculty, Universitas Sebelas Maret Surakarta, Indonesia. A total of 36 1-d-old Joper male chicks were randomly allocated into three dietary treatments; Control diet without fermented SBM (CON), fermented SBM with B. subtilis (P1), and fermented SBM with A. niger (P2) in a completely randomized design. The nutrient digestibility and CMCase activities were analyzed in response to a modified feeding using fermented SBM. Analysis of variance (ANOVA) was employed to analyze data using SPSS® Statistics 25 for Windows. There was a significant difference in the digestibility of crude protein (CP), dry matter (DM), crude fat, nitrogen-free extract (NFE), and organic matter (OM) between the control and treatment groups (P < 0.05). However, crude ash and fibre digestibilities are relatively similar (P > 0.05). Following the insignificant result of fiber digestibility, CMCase activities did not differ significantly (P > 0.05). To conclude, feeding Joper chicken with fermented SBM seems promising in achieving optimized digestibility of nutrients due to significant results, especially in CP digestibility. Additionally, within the treatment groups, B. subtilis (P1) demonstrated slightly better performance compared to A. niger (P2).

Abstract

The meat quality of Jawa Super Male Chicken is attributed to the diet treatment offered since the rearing period. This study aimed to evaluate the meat quality of Jawa Super Male Chickens fed on diets made of soybean meal (SBM) fermented with Bacillus subtilis or Aspergillus niger. The experimental groups were control group without steam conditioning or fermentation (P0), SBM fermented with Bacillus subtilis or SBM BS (P1), and SBM fermented with Aspergillus niger or SBM ASP (P2). Ninety chickens aged 21 days (210 ± 3.69 grams) were assigned to three groups, and replicated six times with five birds. Basal diets were made of corn-soybean with 16% crude protein (CP) and 2,950 Kcal metabolic energy (ME). The results showed significant differences (P<0.05) in the physical attributes (cooking loss, water holding capacity) and chemical properties (fat content) but the collagen and protein content did not differ significantly (P>0.05). The meat pH was within the normal range of 5.90 – 5.93. Conclusively, SBM fermented with Bacillus subtilisor Aspergillus niger increased meat quality.

Abstract

Soybean meal, feedstuff obtained from soy seed oil extraction, is a common feed ingredient for poultry despite containing antinutritional factors (ANFs), which can alter digestive activity and decrease poultry productivity. ANFs are reportedly eliminable by fermentation protocol. This study identified the effect of thermomechanical Fermented Soybean Meal (FSBM) on Javanese Super Chicken’s protease activity, blood metabolism, and growth performance. A total of 90-day-old chicks (DOCs) of Indonesian male Javanese Super Chicken were allotted to three treatment groups: CON (non-FSBM); T1 (FSBM with Bacillus subtilis); T2 (FSBM with Aspergillus niger). All groups were replicated six times with five birds each. The study was conducted for 76 days, and all birds were healthy and vaccinated with Newcastle Diseases (ND), Lasota, and Gumboro A. The result indicated that thermomechanical FSBM affected significantly (P<0.05) daily feed intake, average daily gain, feed conversion ratio, total protein, total albumin, and globulin. Protease activity was not affected by the treatments.

Abstract

Goat are widely raised as meat producer. Goat livestock in Indonesia are generally used as a side business. This study was carried out at Huda Kambing Sumber Barokah (KSB) Farm which is located at Jl. Klodran – Kadipiro, Banjarsari, Surakarta, Central Java. There were 250 goats in KSB. The aim of this study was to analyse and evaluate the management system of rearing and analysis business feasibility at KSB Farm. Seven goats were used as a sample to evaluate the performance productivity. Data included feed intake, body weight, and feed cost were calculated daily for 30 days. Cash flow and investment were taken from interview. The value of ADG; FCR; FCG and FER were 102 g/day; 8,94; Rp. 29.244,00 and 11,15 %. The Value of BEP; BCR; and FER were Rp. 303.639.908,00; 1,4; dan 4 years. From this study, it could be concluded that management system of KSB Farm is good, and the business feasibility analysis showed that this farm is feasible to develop.

Abstract

This study aimed to determine the effect of infertile eggs in the feed on slaughter weight, carcass quality and non-carcass quality in super native chickens. A total of 40 super-male chickens aged eight weeks were used in this study. The design of this study used a completely randomized design with a directional pattern with 4 treatments and 5 replications. The treatments in this study included: P0 (100% basal feed without additional infertile eggs); P1 (basal feed 96,7% + 3,3% infertile eggs); P2 (basal feed 93,4% + 6,6% infertile eggs) and P3 (basal feed 90,1% + 9,9% infertile eggs). The data were using analysis of variance (ANOVA), if significant results were obtained, they would be tested using Duncan's Multiple Range Test (DMRT). The results showed that the use of infertile eggs into the feed up to a level of 9.9% could increase the slaughter weight, carcass weight and carcass percentage (P<0.05). The addition of infertile eggs up to the level of 9.9% can also reduce the percentage of non-carcasses in super native chickens (P<0.05). The conclusion of this study is that infertile eggs can be used as feed ingredients for feed up to a level of 9.9% to increase slaughter weight, carcass weight, carcass percentage and can reduce the percentage of non-carcass in super native chickens.

Abstract

This research aims to examine the correlation between digestible crude protein (DCP) and digestible crude fiber (DCF) on methane gas production from fermented rice straw using urea and urine. The material in this study was used included eight indigenous rams aged ± 1.5 years with a weight of ± 20 kg. The feed provided consisted of concentrate and rice straw fermented with urea (P1) and rice straw fermented with urine (P2). Feed was given twice daily, and water was provided ad libitum. Data collection of digestible crude protein and digestible crude fiber was conducted by total collection method in metabolic cages for 7 days, while methane gas production measurement was conducted for 2 x 24 hours. The results showed differences in correlation values between the two types of treatments. Treatment with rice straw fermented with urea had correlation values of 0.937 for digestible crude protein and 0.507 for digestible crude fiber with coefficient of determination values of 87.9% for DCP and 25.7% for DCF. Meanwhile, in the treatment with rice straw fermented with urine, the correlation values were -0.632 for DCP and -0.991 for DCF with coefficient of determination values of 40.0% for DCP and 98.3% for DCF. The conclusion from this research is that the difference in correlation values is caused by the nitrogen source used for fermentation and the presence of accompanying compounds found in cattle urine used for rice straw fermentation.
