Abstract

The research aims to analyze the production potential and opportunities to increase the productivity of each cross-bred animal based on its quantitative characteristics. The livestock material used in this research was 50 Sera chickens (Sentul chickens x Arabian chickens) and 50 Mera chickens (Merawang chickens x Arabian chickens). The research was carried out by raising chickens from DOC to 3 months of age. The quantitative data involve body weight, weight gain, and body measurements (Head Length, Head Circumference, Head Height, Neck Length, Neck Circumference, Wing Length, Back Length, Back Height, Chest Length, Chest Width, Shank Length, Shank Circumference, Length Third Finger and Pubic Bone Distance). The quantitative data that has been observed is then analyzed through the t-test. Then, PCA is used to identify body shape and size determinants in Sera and Mera chickens. Statistical analysis was carried out using Minitab software version 21. The results obtained showed that the body weights of Sera and Mera chickens were significantly different (p<0.05) from DOC to 3 months of age. A significant increase in productivity in crosses between Sentul chickens and Arabian chickens and Merawang chickens with Arabian chickens occurs starting at 1-2 months. Sera and Mera chickens' body sizes differed significantly (p<0.05). The total diversity of PC1 in Sera chickens was 79.8%, and in Mera chickens, it was 70.6%. Meanwhile, the total PC2 diversity of Sera chickens was 17.7%, and Mera chickens were 7.9%. In conclusion, Sera chickens have the highest quantitative characteristics compared to Mera chickens, and the highest body weight gain occurs at 1-2 months in both Sera and Mera chickens.  Based on principal component analysis. The body size characteristic of Sera chickens is shank length, while in Mera chickens, it is chest length. The distinct shape of Sera chickens is body height, while in Mera chickens, it is shank length.

Abstract

Indonesia's annual beef consumption is experiencing a steady rise. In 2021, the per capita beef consumption amounted to 2.56 kg per person per year, resulting in a total of 696 million kilograms consumed across the country. This quantity is equivalent to the slaughtering of approximately 3.98 million cattle annually. With the increasing growth of the feedlot industry, cattle farmers, including feedlot operators, have the opportunity to enhance the value of agricultural companies in Indonesia by utilizing local feedstuffs. The objective of this study was to assess the suitability and nutritional value of indigenous feed sources for beef cattle in Indonesia. The research utilized feedstuff varieties and characteristics sourced from feedlots spanning since 2012-2021. The employed methodologies encompassed surveys, interviews, and questionnaires. This research involved the collection of both primary and secondary data. The potential and quality of local feedstuff were described using descriptive analysis. This research showed that eight types of local feedstuff could be categorized as energy sources including dehydrated cassava chips with a total digestible nutrients (TDN) value of 84.2% and bran pollard with a TDN value of 66.6%. The fiber sources consisted of corn cob (37.7% crude fiber), coffee husk (38% crude fiber), cocoa bean shell (20% crude fiber), tapioca solid waste/onggok (22% crude fiber), and palm kernel meal (22.1% crude fiber). The protein source consisted of copra meal with a protein content of 22.4%. The physical test most frequently inspected the feed color (18.1%) and odor (18.1%). Moisture examination (24%) was the most frequently used of proximate analysis was employed to identify the chemical composition. In conclusion the existence of eight local ingredients which were categorized into three different types: energy source, protein source, and fiber source commonly used in the concentrate formula for beef cattle feedlots in Indonesia.

Abstract

The aim of this study was to evaluate the effect of Waru Leaf Flour  (WLF) and Direct-Fed Microbials (DFM) supplementation on volatile fatty acid (VFA) and ammonia (N-NH3) concentrations, total protozoa, microbial protein synthesis (MPS), and the specific activity of cellulase, amylase, protease in rumen fluids of local beef cattle. The study was conducted as an experimental investigation using a factorial Completely Randomized Design (FCRD). The first factor were three levels of DFM (P) mixed with rice straw (0%, 0.5%, and 1% dry matter of rice straw). The second factor consisted of three levels of WLF supplementation (D) in concentrates (0%, 0.24%, and 0.48% of dry matter concentrate). This resulted nine treatment groups, each it replicated three times.The diet composition consisted of rice straw and concentrate at 40:60 ratio (% dry matter). The interaction between DFM and WLF had a statistically significant impact (p<0.01) on the rumen fluid's total protozoa, N-NH3, and protein content. However, this interaction was not statistically significant (P>0.05) in relation to VFA, MPS, cellulase, amylase, and protease activity. While no significant interaction were observed for total VFA, cellulase, amylase, and protease, DFM supplementation had a statistically significant effect (P<0.01) on reducing enzymes activity, and total VFA (P<0.05). SDS-PAGE and zymography analyzes showed two protease molecules at all treatments with molecular weight of 144 kDa and 133 kDa, cellulase molecules at 62-67 kDa and 19-21 kDa respectively. The addition of DFM showed a new protease band, they had a measurement of 14 and 25 kDa.This study provides valuable insights into enzyme activities in rumen, particularly protease, cellulase, and amylase. The results suggest that the combination of 0.24% WLF and 0.5% DFM supplementation holds promise for optimizing rumen conditions and improving the performance of local beef cattle.

Abstract

Iron's significance in human health and diseases has been extensively examined in recent reviews, leading to the consensus that iron insufficiency is a worldwide issue requiring immediate attention. Fe-enriched eggs are significant for delivering this essential trace mineral to humans. This study aimed to assess the effects of adding premix minerals on the physical and chemical quality of eggs and the yolk's iron levels. 1,680 Lohman brown laying hens, aged 31 weeks (body weight: 1.70±0.11 kg, egg production average: 81.2 %), were divided into two groups (n = 840) and fed different diets for six weeks. The diets included a basal diet (CON) and a diet enriched with a 2.5 g / kg food premix mineral (PM-Fe). The findings indicated that there was no impact on the physical and chemical quality of the eggs. However, compared to the control diet, the addition of premix significantly enhanced the iron level in the yolk after 42 days (p<0.05). To summarize, adding 2.5 g per kg of premix mineral (which contains 12.6 g per kg of iron premix) can result in a 23.4% rise in iron content in the diet and a 15.7% increase in iron content in the egg yolk.

Abstract

The study aimed to evaluate the impact of dietary supplementation with Angelica gigas Nakai (AGN) root extract on growth performance, hematological indices, and serum biochemical parameters in broiler chickens. A total of 320 straight-run Cobb broiler chicks from a commercial hatchery were distributed among four treatment groups: Basal diet (BD) as the Control; Treatment 1 (T1): BD + 2 g/kg AGN; Treatment 2 (T2): BD + 4 g/kg AGN; and Treatment 3 (T3): BD + 8 g/kg AGN), each comprising eight replicates with 10 birds per replicate. The supplementation of AGN resulted in dose-dependent improvements (P < 0.05) in body weight, gain, and feed efficiency. On both day 21 and day 35, increasing AGN dosage in the diet led to a significantly higher (P < 0.05) values of red blood cells (RBCs), white blood cells (WBCs), hemoglobin (Hb), and packed cell volume (PCV). By day 21, AGN supplementation dose-dependently decreased (P < 0.05) serum alkaline phosphatase (ALP), aspartate aminotransaminase (AST), alanine aminotransaminase (ALT), urea, and creatinine levels. Meanwhile, AGN dose escalation correlated with a notable increase (P < 0.05) in serum total protein (TP), albumin, and globulin levels. On day 35, increasing AGN levels led to a significant reduction (P < 0.05) in serum AST and ALT activity, along with lowered serum glucose, cholesterol, triglycerides, urea, and creatinine levels. In conclusion, AGN supplementation enhanced growth performance and positively influenced hematological indices and serum biochemistry profiles in broiler chickens. The study confirms the safe and effective utilization of AGN at an 8 g/kg (0.8 %) feed additive dosage to optimize broiler performance. These findings provide valuable insights into the potential benefits of AGN in poultry nutrition.

Abstract

The suitability of a product's perceived value to consumers’ needs determines the success of offerings. Food safety labels as product attributes have not yet become a concern for most consumers. This research analyzed consumer attention to NKV certification and perceptions of choosing NKV-certified livestock food products regarding demographic profiles. This research was conducted using a survey and data collection was carried out online via social media between June and August 2023. Respondents were determined using a purposive sampling method with the criteria that they had ever shopped for processed livestock products in the last month and were over 18 years old. A total of 210 data were collected and analyzed using descriptive statistical methods and non-parametric Chi-Square. The results showed that behavior regarding NKV certification is positively related to age, education level, and income variables but not to gender. Further analysis showed that the perception of purchasing NKV products is wise and a first choice is greater in groups with older age and higher education levels. Furthermore, the perception of this purchase has the potential to occur in the group of respondents with an income of at least IDR 1,500,000. Furthermore, NKV has not been considered by all respondents, only 14.28% of respondents thought NKV was an important attribute. This study concluded that demographic variables such as age, education level, and income should be deliberated in profiling the market segment for NKV-certified livestock food products. Behavior to purchase NKV products increases in older age groups, higher levels of education, and income.

Abstract

This study aimed to determine the effect of L-isoleucine supplementation in the diet on the growth performance of Kampong chickens at the starter phase (1-6 weeks). This study was conducted at Kefamenanu, East Nusa Tenggara Province, Indonesia, from May to June 2023. A total of two hundred and fifty-week-old Kampong chickens with an average initial weight of 59.03±0.52 g were used in the study. The chickens were divided into five treatments with five replications based on a completely randomized design. The diet treatments were: T0 (control feed); T1 (T0 + 0.20% L-isoleucine, NRC, 1994 for broilers); T2 (T0 + 0.30% L-isoleucine); T3 (T0 + 0.40% L-isoleucine); and T4 (T0 + 0.50% L-isoleucine). The parameters observed were body weight, weight gain, feed intake, feed conversion ratio, carcass weight, and carcass percentage. The data obtained were analyzed using variance analysis and the Duncan test. The study result showed that the groups T3 and T2 had the highest body weight (330.76±1.29; 334.48±1.47 g/bird, respectively). The highest weight gain was in group T2 (275.54±1.39 g/bird/5 weeks). Group T3 had the highest feed intake (613.15±5.79 g/bird/5 weeks) and the lowest feed conversion ratio (2.22±0.02). The highest carcass weight was in groups T2 and T3 (189.95±1.17 and 189.32±0.65 g/bird, respectively), while the highest carcass percentage was in group T2 (57.43±0.47 %/bird). The statistical analysis indicated that body weight, weight gain, feed conversion ratio, and carcass weight were affected by the level of L-isoleucine (p<0.05). In contrast, feed intake and carcass percentage were not significant. It was concluded that supplementation with 0.40% L-isoleucine to the diet of Kampong chicken resulted in optimal growth performance at the starter phase (1-6 weeks).

Abstract

The farmers have encountered challenges in conducting livestock trade due to the absence of dealer activity caused by Anthrax and Foot Mouth Disease (FMD) epidemics. In this context, it is crucial to utilize technology in livestock marketing to obtain current market information from distant marketplaces and reduce the risk of contagion. To meet these purposes, a mobile phone application has been developed in order to be used by cattle farmers; after that, market testing has been conducted to gain feedback and determine the segmentation. Thus, the study aimed to examine the differences in the perceived ease of use, perceived usefulness, and social impact amongst farmers who are willing and unwilling to embrace a mobile phone application for digital marketing. A total of 968 cattle farmers were surveyed with stratified random sampling techniques in the Special Region of Yogyakarta. The data obtained were analyzed using mean difference inferential analysis. The result showed that farmers with various categories of age, education, farm revenue, farmers group, farmer experience, cattle ownership, and regions have significantly different (p<0.01) perceived usefulness (PU), perceived ease of use (PE), and social influence (SI) on mobile applications for livestock digital marketing. Furthermore, farmers willing to adopt mobile application have significantly higher (p<0.01) PU, PE, and SI factors. This study recommends mobile app developers evaluate potential user needs and background factors that may influence farmers' interest.

Abstract

This study aimed to examine the effect of marlin fish (Istiompax indica) byproduct meal (MFBM) mixed with some other feed ingredients such as yellow corn (YC), rice bran (RB), broken rice (BR), and top mix (TM) as a mixture feed (MF) in replacement fractionally a commercial ration (CR) on carcasses and organs of broiler chickens. As a comparison,  commercial local fish meal (CLFM) was used instead of MFBM in the MF. A total of 100 DOCs, strain MB 202, were raised for 35 days of age to feed the experimental rations. The experimental rations were: CR= 100% CP511/512 (control), MFBM4= 80% CP511/512 + 20% MF1 containing 4% MFBM, MFBM8= 80% CP511/512 + 20% MF2 containing 8% MFBM, CLFM4= 80% CP511/512 + 20% MF3 containing 4% CLFM, and CLFM8= 80% CP511/512 + 20% MF4 containing 8% CLFM. The research used a completely randomized design (CRD) with five treatments, four replications, and two subsamples. Data were analyzed by Analysis of Variance (ANOVA) and continued by Duncan’s multiple range taste (DMRT) only if the results detected a significant difference. This study showed that at 4% usage within the MF, using MFBM did not indicate a significant difference in the whole carcass and cuts-up weights than using CLFM. However, at the level of 8% within an MF, the former was significantly higher (p<0.05) on the whole carcass and breast weight than the latter. In conclusion, marlin fish byproduct meal (MFBM) could be used up to 8% to produce better whole carcass and breast weight compared to commercial local fish meal (CLFM) without adverse effects on the internal organs of broilers.
