- Estradiol Concentrations During Estrous in Dairy Cattle and Its
Association with Pregnancy and Genotype Diversity
Authors: Yuliati Wahyu Setyorini, Edy Kurnianto, Sutopo Sutopo, Sutiyono Sutiyono
Pages: 120 - 126
Abstract: This study determined estradiol concentrations during estrous in dairy cattle and its association with pregnancy and genotype diversity. A total of fifteen female dairy cows that had been identified with their genotype type using the PCR-RFLP method on follicle-stimulating hormone receptor (FSHR) and prolactin (PRL) genes were used in this study. The parameters measured were serum estrogen concentrations during estrous, estrous intensity, and pregnancy. Estradiol concentrations were analyzed by the enzyme-linked immunosorbent assay (ELISA) method. The data were analyzed using a general linear model procedure in the SAS program. The results showed that the average estradiol concentrations in dairy cows during estrous were 60.06±33.25 pg/ml. There was no difference (P>0.05) in estradiol concentrations in different classifications of age, body condition score (BCS), and estrous intensity. Estradiol concentrations in the group that showed success in post-insemination pregnancy were higher and significantly different (P<0.05) from the non-pregnant group. Differences in genotype variations of the FSHR and PRL genes had no significant effect (P>0.05) on the estradiol concentrations. In conclusion, estradiol concentrations during estrous were not associated with age, BCS, estrous intensity, and genotype diversity of FSHR and prolactin genes but were associated with pregnancy.

- Effect of the Additional Natural Compound in Litter on Performance and
Health Parameter of Broiler
Authors: Joko Sujiwo, Bambang Ariyadi
Pages: 127 - 133
Abstract: This study investigated the impact of adding natural compounds, including zeolite, charcoal, Quicklime, and limestone, to broiler litter on broiler chickens' performance and health parameters. The experiment was conducted using a completely randomized design with five treatments: T1 = fresh rice husk without additional compound, T2 = 10% zeolite, T3 = 10% charcoal, T4 = 5% quicklime, and T5 = 5% limestone. The results showed that adding natural compounds improved broilers' growth rate, with the highest final body weight observed in the T5, 2459.78 g. Mortality rates did not differ significantly among treatments. The addition of natural compounds did not affect (P > 0.05) the relative weight of the immune organ, except the liver. The addition of natural compounds did not significantly affect blood parameters, including red blood cell count, white blood cell count, and haemoglobin levels (P > 0.05). Additionally, the incidence of footpad dermatitis was lower in litter treated with natural compounds than in untreated litter. In conclusion, adding natural compounds to broiler litter can enhance broiler performance and health without adverse effects, promoting overall growth and reducing footpad dermatitis.

- Assessing Nutrient Consumption and Fattening Performances of Simmental
Crossbred Bulls Fed Concentrate Feed and Chopped Forage Under Different
Times on Feed Offered
Authors: Theo Mahiseta Syahniar, Dwi Agus Setiawan, Mira Andriani
Pages: 134 - 139
Abstract: This study aimed to determine nutrient consumption, body weight gain, feed conversion, and feed efficiency of Simmental crossbred bulls through different feeding management specifically for levels of time on feed offered. Nine bulls were allocated on three different level treatments and three replicates. They were T0=feeding whole concentrate first in the morning then offering whole chopped forages after 6 hours later; T1=feeding half of the concentrate first then offering half of the chopped forages after 2 hours later in the morning and afternoon; T2=feeding half of the concentrate and chopped forages simultaneously in the morning and afternoon. Bulls were fed twice daily and had free access to drinking water ad libitum. Parameters observed were nutrient consumption, daily gain, feed conversion and efficiency. Data were analyzed using ANOVA and further analysis by DMRT for the significant parameter. The results showed that the treatment of different feeding management presented significantly different (P<0.05) on nutrient consumption; however, it had no effect (P>0.05) on daily gain, feed conversion, and feed efficiency. Feed-offered time differences affected nutrient consumption but did not alter the concentrate and forage ratio consumed or cattle performances.

- Reproduction and Production Performance of Swamp Buffalo (Bubalus Bubalis)
at The Small-Scale Holder Farmer in Sragen Regency, Central Java,
Indonesia
Authors: Nimas Alifia Nastiti, Joko Riyanto, Ratih Dewanti, Muhammad Cahyadi, Ari Kusuma Wati, Wari Pawestri, Yuli Yanti
Pages: 07 - 07
Abstract: This research was aimed to determine the performance of swamp buffalo reproduction and production at the small-scale holder farmer in Sragen Regency, Central Java, Indonesia which has been carried out from June to September 2021. The method used in this research was a survey with a census (complete) sample determination. Data collection applies to interviews, observations and literature studies. Research parameters used in reproductive performance were calving interval (CI), service per conception (S/C), age of the first estrus, age of first birth and postpartum estrus. In contrast, production performance parameters were chest circumference, body length and estimated body weight. The result of research on reproductive performance showed that the average CI were 13.2±0.9 months, S/C 1.25±0.4 time, age of first estrus 2.7±0.6 years, age of first birth 3.7±0.5 years and postpartum estrus were 30–60 days. The result of research on the production of male buffalo body length was 205.3±1.7 and the body length of female buffalo was 127.2±4.3 cm, whereas the chest circumference of female was 205.3±1.7 cm and the chest circumference of the male was 189±2.8 cm. The estimated body weight of females and males was 516.7±7.7 kg and 445.2±11.9 kg. Based on the result of the research, the characteristics of swamp buffalo reproduction and production in Sragen Regency were classified as good.
