    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 favorabl

    Cattle is meat-producing livestock of the large ruminant. The environmental conditions must remain in the thermoneutral zone because this affects livestock productivity. An environmental modification related to microclimate management is required through a misting system using a water sprinkler. The study was conducted in one of the barns of the Sekolah Peternakan Rakyat (SPR) Maju Bersama livestock group in Drokilo Village, Kedungadem District, Bojonegoro Regency, East Java. The purpose of this study was to analyze the microclimate management of the barn through the misting system in order to improve the physiological response of cattle. The variables observed were the air temperature, air humidity, Temperature Humidity Index (THI), respiratory frequency, heart rate, rectal temperature, and body surface temperature. Body surface temperatures were measured on the face, back, and rump. The analytical method used in this was unpaired T-test five replications. The results showed that the average microclimate data for barn cattle were: air temperature 27.40±0.59°C, air humidity 83.92±1.55%, and Temperature Humidity Index (THI) 79.59±1.06. The results showed that the average physiological response data for cattle were: heart rate 47.02±2.29 beats per minute, respiration rate 16.94±1.26 beats per minute, and rectal temperature 38.65±0.27°C. The results showed that the average body surface temperature data for the face was 37.03±0.38°C, the back was 36.33±0.59°C, and the rump was 36.28±0.68°C. The results showed that the treatment before and after the morning measurement water misting was significantly different (p<0.05) in all the observed variables. Water misting has the effect on decreasing the air temperature, humidity, Temperature Humidity Index (THI), respiratory rate, heart rate, body temperature, and rectal temperature

    The body's Blood Urea Nitrogen (BUN) concentration could be used as diagnostic information for interpreting animal nutritional status, improving nutritional management, and preventing metabolic disorders in ewes during the reproductive phase. This study aimed to evaluate the reproductive success rate and changes in the BUN status of Garut ewes fed sorghum-Indigofera in Majalengka District – West Java, Indonesia. Twenty-eight multiparous Garut ewes with an average body weight of 30 kg, aged 2-3 years or parity from 3rd to 4th, and non-pregnant were separated into two feed treatment groups; divided field grass (FG) and sorghum-Indigofera (SI) mixed feed. This study was designed using a Complete Randomized Design (CRD). After one month of feed acclimatization, all ewes were served an estrus synchronization protocol and mated naturally. A pregnancy test was carried out on the 28th day after mating using ultrasonography (USG). Seven blood samples were taken (1 time in the pre-mating phase and three times each in the pregnancy and lactation phases), and the BUN parameter was analyzed. The results showed that SI feed increased the number of ewes pregnant and giving birth compared to FG (10 vs. 9 and 9 vs. 6, respectively). Meanwhile, the average value of the BUN content of ewes in both FG and SI treatments during the premating, pregnancy, and lactation phases did not show any differences (p>0.05). The concentration of BUN is still in normal condition even though it has decreased from pre-mating until the lactation phase. It can be concluded that Sorghum-Indigofera mixed feed could increase reproductive success. However, the average value of BUN in the two types of feed treatment experienced the same status change in all reproductive phases. Both can overcome the energy deficit problem if they have sufficient feed
