This study aims to investigate the diversity of quantitative characteristics and GH genes, along with the association between GH genes and quantitative characteristics. The research material consisted of 96 KUB chickens aged DOC-2 months and corresponding blood samples. The t-test was utilized to determine differences in body weight, weight gain, and body measurements between male and female KUB chickens, and assess the diversity of the GH gene. T2-Hotelling analysis was employed to compare body measurements between male and female KUB chickens, while principal component analysis was used to identify size and shape characteristics. Male KUB chickens' average body weight, weight gain and body size were significantly (p<0.05) higher than females. The analysis of the growth hormone gene exhibited three genotypes: +/+ (0.51), +/- (0.35), and -/- (0.14). Additionally, two alleles were identified: (+) accounting for 0.68% and (-) accounting for 0.32%. The growth hormone gene MspI of KUB chickens demonstrated polymorphism, with X2 count (2.93) < X2 table 0.05 (3.84). The heterozygosity value in the KUB chicken population was 0.43, and the obtained PIC value was 0.38. The genotype +/+ of the growth hormone gene in KUB chickens was significantly higher (p<0.05) than genotypes +/- and -/-.In conclusion, male KUB chickens exhibited higher body weight, weight gain, and body measurements compared to female KUB chickens. The chest circumference served as the identifier for body size in both male and female KUB chickens, while the length of the upper body and tibia length distinguished the shape characteristics of male and female KUB chickens, respectively. KUB chickens' growth hormone gene MspI was associated with body weight, weight gain, and body measurements, with the (+/+) genotype being the most favorable

This study aims to determine the effect of 40°C warm water and sodium hypochlorite solution (NaOCl) on the hatchability of KUB chickens through artificial hatchery. The NaOCl concentrations used in this study were 0.25% and 0.5%. The hatching eggs used are the production of KUB hens which are kept intensively in the UPBS Poultry Departmen, Assessment Institute for Agricultural Technology (AIAT) of North Sumatra. The research procedures applied in this study were collection of hatching eggs, fumigation of machines and equipment, setting of machines and hatching eggs, washing of eggs with cherry leaf extract and hatching of eggs for 21 days. During the hatching process, observations were made on the variables that had been determined. The observed variables were egg shape index, egg weight loss, shell temperature and hatchability. The method used was a completely randomized design (CRD) with 3 treatments and 300 replications. The results showed that the shape index of the eggs that hatched in this study was 76.71 - 77.38%, the P2 treatment experienced the most stable weight loss compared to other treatments. The conclusion in this study P2 (0.25% NaOCl) effective in the highest egg hatchability.

The application of cryopreservation to preserve germplasm in such specific breed requires preliminary studies, primarily related to the resistance of spermatozoa to low temperatures (4 – 5 °C) as measured by their motility and longevity. In this study, semen taken from five phenotypes of Kokok Balengeek Chicken (KBC) (Biriang, Jalak, Kinantan, Kuriak, and Taduang) was used to evaluate the effect of Ringer’s Lactate-egg yolk diluent on longevity and motility of spermatozoa. The treatments consisted of Ringer’s Lactate (RL) solution added with egg yolk at a concentration of 1% (RLKT1), 3% (RLKT3), and 5% (RLKT5). Evaluation of fresh semen showed that the spermatozoa of Jalak had the highest motility, namely 75.63 ± 0.5% (P<0.05). Post-dilution longevity and motility observations were carried out at 0, 24, 48, and 72 h, significantly decreasing each time (P<0.05). The lowest range of reduction was found in Jalak spermatozoa diluted with RL with longevity of 7.75 ± 0.70 days. Overall, the RL diluent showed the highest motility after 24 h, namely 41.13 ± 2.27%. Adding egg yolks to Ringer's Lactate solution could not maintain the motility of KBC spermatozoa when stored at 4-5°C for 48-72 h.

This study aimed to evaluate the physical quality of the wafer supplement with different binders and evaluate the performance of laying hens fed the supplement wafer in drinking water. The rearing stage used 64 Isa Brown chickens raised for 12 weeks. Stage 1 of the experiment used a 3x4 Completely randomized design (T1: Pollard, T2: Cassava Flour, T3: Tapioca Flour Waste). Phase two of the study used a completely randomized design with two treatments x 4 replicates x 8 chickens (P0: without supplement wafers, P1: supplement wafers). The variables observed were the wafer's physical quality and Isa Brown's performance. Different adhesives in the manufacture of wafers produced no significant difference in water content (p>0.05) but significant differences (p0.05) feed consumption, drinking water consumption, Feed Conversion Ratio (FCR), egg weight, and daily egg production but did affect (p<0.05) chicken mortality. The conclusion is that wafers with the best physical quality use cassava flour binder, and giving wafer supplements in drinking water can reduce mortality.

Milk production and composition are the main factors in the dairy industry. However, these traits are influenced by several factors, such as genetic factors. The CSN2 gene exon 7 is one of the genes that can affect the protein composition of goat milk. Several studies on the CSN2 gene exon seven have been conducted on Italian and Indian goat breeds, and their genetic variations have been found. Studies about CSN2 gene exon seven polymorphisms in Indonesia have been completed but found no variations. Therefore, this study aims to find genetic variations of CSN2 gene exon 7 using the Sanger Sequencing Method. Ninety-five blood samples of 66 Sapera, 15 Saanen, and 14 Etawa Grade goats were collected from the Livestock Research Center, Ciawi. Genetic diversity was calculated using PopGene32 programs. The results found two polymorphic SNPs in all three dairy goat breeds, namely g.8946C>T and g.8956G>A. Three genotypes found in SNP g.8946C>T are CC, CT, and TT, while a new SNP g.8956G>A found two genotypes (GG and GA). In conclusion, SNPs g.8946C>T and g.8956G>A are polymorphic. Additional research should be conducted to determine whether there is any association between these 2 SNPs and milk production and quality.

Transporting livestock is a common practice in agriculture, but it can be a stressful situation for the animals. This stress can lead to physiological responses like live weight loss, changes in blood cortisol levels, and immune suppression. Goats are particularly sensitive to transportation stress and stress-induced diseases. In this study, we investigated the effects of road transport on the physiological condition of 33 goats (13 Anpera goats and 20 Boerka goats) transported for 72 hours over approximately ±2.000 km. Live weight loss was determined by comparing the body weights of the goats before and after transportation. We measured psychological responses (heart rate, respiratory rate, rectal temperature), blood parameters (Blood urea nitrogen/BUN, creatinine, glucose), cortisol, and hematological parameters. The results showed that transportation caused an average weight loss of 4.05 kg/head (14.22%). Heart rate decreased by 14.71 x/minute after transport, while respiratory rate and rectal temperature increased by 8.44 x/minute and 0.41 units, respectively. BUN levels increased by approximately 10.92 mg/dL (35%) and glucose levels increased by approximately 30.07 mg/dL (48%). Hematological parameters also showed significant changes, with transportation causing alterations in WBC, RBC, hemoglobin, hematocrit, MCV, and MCH levels. The study also showed an interaction between the sex and breed of goats on BUN, glucose, MCV, MCH. The comparison between Anpera goats and Boerka showed that transportation had significant influence on heart rate, rectal temperature, cortisol, RBC, haemoglobin, RDW. In conclusion, transportation for 72 hours caused stress on goats, leading to weight loss, changes in psychological behavior, and blood parameters, and the breed and sex of the goats played a crucial role in the observed changes.

This study aims to determine the effect of in-ovo injection of L-arginine into local chicken eggs on embryo development and chick performance of local chicken. A total of 160 eggs were incubated using semi-automatic incubator with temperature of 37-38C and relative humidity of 55-65%. The injected L-arginine solution has a concentration of 0.5% (m/v). In treatment was divided into 4 groups, the first treatment was without injection (control), the second treatment was the injection of 0.2 mL L-arginine solution 0.5% (m/v)/egg, the third treatment was the injection of 0.4 mL L-arginine solution. 0.5% (m/v)/egg, and fourth treatment was the injection of L-arginine solution 0.6 mL 0.5%(m/v)/egg. The results showed that embryo mortality and hatchability were lower with L-arginine injection treatment than without injection. All treatments showed no effect on extraembryonic fluid absorption, but there was an increase in embryo weight in the injection treatment 0.2, 0.4, 0.6 mL L-Arginine 0.5% /eggs 2,355 g, 2,577 g, 2,705, respectively. In conclusion, an in-ovo injection of L-arginine in local chicken eggs has a good effect (the beneficial effect) on embryo death and embryo performance. Injection of 0.4 ml L-Arginine 0.5% /eggs improved hatchability and Newly Hatched Chick Weight (NHCW).

The safety of poultry products, especially broiler chickens, can be stated to be relatively low. Antibiotic growth promoter (AGP) is used to improve chicken performance and maintain immunity. The ban on the use of AGP triggers the innovation of other materials to replace the function of AGP. Biopeptide is a solution that can be used. Biopeptides can be made from materials with a high protein content, for example, waste from chicken slaughterhouses. The waste that can be used is chicken feet, biopeptides produced from hydrolytic proteins have antioxidant and antimicrobial properties. These properties can improve the performance and immune system of broiler chickens. The aim of the study was to examine the supplementation of biopeptides from chicken feet on the immune system (total Escherichia coli and internal organ) and the growth of broiler chickens. The research material was 200 day old chickens of broiler strain cobb unsex, which were reared for 42 days of the rearing period. The treatment feeds were P0: basal feed, P1 basal feed + 2% biopeptide, P2: basal feed + 4% biopeptide, P3: basal feed + 6% biopeptide. The collected data were analyzed using analysis of variance with the Tukey test (BNJ). The results showed that biopeptide supplementation from chicken feet had a significant (P<0.05) effect on total Escherichia coli, spleen weight, bursa of Fabricius weight, body weight gain, and feed efficiency for broiler chickens. However, the results of the study had no significant effect (P>0.05) on liver weight and Avian Influenza antibody titers for broiler chickens. Biopeptide supplementation from chicken feet can reduce total Escherichia coli, and spleen weight, and increase the bursa of Fabricius weight, body weight gain, and feed efficiency for broiler chickens. Biopeptide supplementation from chicken feet of 6% gave the best results in body weight gain and feed efficiency.

Aflatoxin B1 is a toxin produced by the fungus Aspergillus flavus which reduces the development and function of organs in broilers. The aim of this study was to determine the effect of adding binder toxin from different bentonite to feed contaminated with AFB1 on productivity, intestinal morphology, and liver toxicity in broilers. A total of 60-day old chick male broilers were placed in 12 pens. Each treatment consisted of three replicates, each replicate containing five broilers. Treatment in the study consisted of P0 (control, basal diet, without the addition of AFB1), P1 (P0 + 100 µg/kg AFB1 + 4 g/kg calcium bentonite Type A), P2 (P0 + 100 µg/kg AFB1 + 4 g/kg calcium bentonite Type B), and P3 (P0 + 100 µg/kg AFB1 + 4 g/kg calcium bentonite Type B + kerolite + saponite). Treatment diets were given to broilers from day 22 to 35 (finisher phase). The results showed that the toxin binder on AFB1 contaminated feed had no effect on feed consumption, body weight gain and feed conversion (p>0.05). Addition of toxin binder on AFB1 contaminated feed increased the relative weight of the duodenum (p=0.024), although P3 was not significantly different. Treatments had no effect on villus length, crypt depth, and ratio of villus length to crypt depth (p>0.05), but decreased villus width (p=0.013). The addition of toxin binder tended to decrease the villus area (p=0.055). SGOT and SGPT did not show differences between treatments. AFB1 contamination with the addition of toxin binder showed signs of toxicity on liver histopathological observations. Based on the research, it can be concluded that the addition of binder toxin in feed contaminated with AFB1 can reduce the negative effect on the development of intestinal villus and chemical effect to the liver. Toxin binder Type B has the best efficacy for reduce the negative effect

This study was aimed to measure the farmers' commitment, accessibility of resources (information, capital, and assistance), and the correlation between those variables. The research method used in the current study was the survey method. The location was purposively selected in Pemalang Regency, the regency with the largest buffalo population in Central Java Province. Three subdistricts (20%) with formal and informal farmers' groups were selected, and there were Taman, Pemalang, and Belik subdistricts. One Village was selected for each subdistrict. Respondents for informal groups were taken by census method. Respondents in formal groups were taken by random sampling, and the number of respondents followed the number of informal groups. There were 136 farmers selected as respondents. (69 from each formal and informal groups). The data were analyzed using the descriptive and rank Spearman correlation methods. The results showed that the farmers' commitment of formal group and informal group members was in the moderate and low categories respectively based on the percentage score interval scaling method. Resources accessibility of formal and informal members of the farmers' group was in the low to moderate category, but the member of formal groups was slightly better. There was a strong correlation between the accessibility of resources with the commitment in the formal groups, whereas in the informal groups there was a moderate to strong correlation between the accessibility of resources with the commitment of buffalo farmers. Based on the conclusion, this study recommend that the government should assist the informal farmer group to establish formal group with the result that would increase farmers accessibility toward information, support, and capital. That condition would increase farmers commitment to continue their buffalo farm business in Pemalang Regency.
