Quality of Bali Cattle Oocytes Post Vitrification with the Addition of Antioxidant Glutathione Sulfihydryl (GSH) in Maturation Media
Full text linkThe success of oocyte maturation in vitro depends on several factors, namely the type of supplement used in the in vitro maturation medium, the quality of the oocytes used, and the risk of contamination and culture conditions. In vitro culture can cause oxidative stress, generating free radicals that can damage cells, so antioxidants are often added to overcome this problem. This study aimed to determine the effect of adding GSH to the maturation medium on the oocyte quality of Bali cattle after vitrification. This research was conducted at the Emryo In vitro Production Laboratory, Institute for Research and Community Service (LPPM) Building, Hasanuddin University, 2023. The study consisted of 4 GSH treatments: 0 mM, 0.5 mM, 1 mM, and 1.5 mM, with 6 replications. The research variables were viability, fractures of the zona pellucida, cytoplasmic shrinkage, and cytoplasmic lysis in post-vitrification and thawing oocytes. The results showed that adding GSH significantly affected oocyte viability (P0.05). It can be concluded that there was an increase in oocyte viability in line with the increase in GSH dose.
Physico-Chemical And Energy Properties Of Biomass Briquettes Composed From Dairy Cow Feces And Coffee Ground With Tapioca Flour Addition
Full text linkCow feces is the rest of the digestive process of the livestock body, while coffee grounds are the rest of coffee brewing, and both are organic materials with fixed carbon that can be utilized as fuel. The purpose of this study was to determine the effect of the addition of coffee grounds in processing dairy cow feces into briquettes on physical properties (color, texture, density), chemical properties (moisture content, ash content, volatile matter, and fixed carbon), and energy value (calorific value, temperature, flame duration). This research method is experimental, with four treatments, each consisting of five repetitions. The treatments in this study consisted of P1 (100 g dairy cow feces + 20 g coffee grounds), P2 (100 g dairy cow feces + 40 g coffee grounds), P3 (100 g dairy cow feces + 60 g coffee grounds), P4 (100 g dairy cow feces + 80 g coffee grounds). The data obtained were analyzed statistically with ANOVA at = 5%. Further tests were carried out using the Duncan test. The results showed that the addition of coffee grounds to dairy cow feces briquettes had a significant effect (p<0.05) on physical properties (density), chemical properties (moisture content, ash content, volatile substances, fixed carbon) and energy value (calorific value, temperature, and flame duration). The addition of 80 grams of coffee grounds (P4) gave the best effect on the performance of dairy cow feces briquettes with a moisture content of 6.94%, ash content of 25.47%, volatile matter of 18.58%, fixed carbon of 49.02%, calorific value of 3717 cal/gr, temperature of 463°C
The Relationship Between Parity to Placental Retention and The Impact on Days Open and Calving Intervals in Dairy Cows at KPSBU Lembang
Full text linkPlacental retention or retensio secundinae is one of the reproductive disorders that often occurs in dairy cows. This will interfere reproductive efficiency, including Days Open and Calving Interval. Retained placenta is defined as the failure to completely pass all of the placenta from the uterus (cotyledon villi) for more than 8 hours after parturition. This study aimed to determine the relationship between parity and placental retention and its impact on lambing days and lambing distance in dairy cows. The research was conducted at North Bandung Cattle Farming Cooperative (KPSBU) Lembang. The method used was data analysis using descriptive analysis and path analysis. The results showed that parity has a significant relationship with placenta retention, and placenta retention with increasing parity can affect days open and calving interval in dairy cows at KPSBU Lembang. Path analysis found that the t-statistical results had exceeded 1.96 with a significant p-value that did not exceed 0.05, so there was a significant relationship between the variables in the study. Dairy cows that have experienced retained placenta at North Bandung Cattle Farming Cooperative (KPSBU) Lembang have low reproductive efficiency, characterized by long open days and calving intervals exceeding the expected time
APPLICATION OF RECTAL EXPLORATION TECHNIQUES FOR PREGNANCY DIAGNOSIS IN GOATS
Full text linkThis study aims to explore the potential of applying rectal exploration (ER) techniques to goats for practical purposes. The principle of pregnancy detection in this technique is based on palpable gestational changes in the goat's reproductive tract in terms of location, consistency, and size. This study used 6 female goats aged 2-3 years with normal reproductive cycles and had given birth and one fertile male goat at the age of 2-3 years. Mating was carried out naturally. Previously, female goats had been in estrus synchronization with a double injection of prostaglandin 1.5 ml/head each intramuscularly with an interval of 11 days. Pregnancy tests were carried out at 30, 40, 50, and 60 days after mating using Real-Time B-Mode Ultrasonography (USG) and ER techniques. In this study, ultrasound was used as the gold standard because this method is more accurate and reliable for the diagnosis of pregnancy in small ruminants. The diagnostics observed in this study were the sensitivity and specificity of the ER technique for diagnosing pregnancy in goats compared to the gold standard. The results showed that four goats that were negatively pregnant with the ER technique also showed that they were not pregnant on ultrasound on all days of the examination stage, and two goats that were positive for pregnancy with ultrasound showed positive pregnancy with the ER technique on examination 50 and 60 days after mating. Based on the results of this study, it can be concluded that the ER technique can be used for an alternative pregnancy diagnosis in goats that is practical in the field
Estimated Model of Correlation Environmental Factor with Crowing Characteristics of Pelung Chickens
Full text linkIndonesia has high biodiversity, one of which is the diversity of local chickens such as Pelung chicken which is included in the singing chicken category. The characteristics of Pelung chicken's crowing sound are thought to be influenced by several factors, including genetic and environmental factors. This research was conducted to determine the relation of environmental factors to the characteristics of the crowing sound. The research was conducted using a survey method with purposive sampling techniques in Bandung, Cianjur and Sukabumi Regencies. The samples used were 32 Pelung chickens. The data observed were the duration, number, and crowing volume of Pelung chicken. When measuring sound characteristics, temperature, humidity, and light intensity were also measured. The data obtained were analyzed using multiple linear regression tests. The results of the research show that the regression equation for Duration and environment is Y=-0.547+0.142χ1+0.02χ2+0.066χ3, while crowing number with environment: Y=-47.48+1.17χ1+0.007χ2+0.423χ3, and Volume with environment: Y=62.563- 0.336χ1+0.01χ2+0.031χ3 with coefficients of determination (R2) of 0.179, 0.096, and 0.023 respectively. This research found that environmental factors such as temperature, light intensity, and humidity influenced the duration and number of Pelung chickens' crowing but did not influence the volume of the crowing sound. It is suspected that other factors and genetic factors are more dominant in influencing crowing characteristics

DESCRIPTION OF SERVICES PER CONCEPTION, CONCEPTION RATE AND PREGNANCY RATE IN DAIRY CATTLE POST FOOT AND MOUTH DISEASE AT KPSBU LEMBANG
Full text linkThe availability of dairy cow milk in Indonesia is still insufficient to meet domestic needs, one of which is caused by the declining dairy cow population due to infectious diseases, namely FMD (Foot and Mouth Disease). Not only does it cause economic losses, FMD also results in a decline in the reproductive status of dairy cows. To assess whether a cow's productivity level is good or not, it can be determined quantitatively by calculating several reproductive efficiency parameters, namely Service per Conception (S/C), Conception Rate (CR) and Pregnancy Rate (PR). The aim of this research is to describe the reproductive efficiency of post-FMD dairy cows based on S/C, CR and PR values. This research used a descriptive approach to data from 1,046 sample animals taken from the KPSBU Lembang recording system, which was then tabulated using the Excel program. Based on the calculation results of reproductive efficiency parameters, the S/C value was obtained, namely 1.635 times, where this value is in the normal category. Meanwhile, for the CR and PR parameters, the values obtained are 49% and 61%, which shows that these values are below the normal

Full text linkThe research explored the use of boiled sunflower seed meal (BSSM) as sustainable feed alternative for broiler chickens, evaluating its impact on their growth and development thereby reducing the industry’s reliance on resource-intensive feed ingredients. One hundred and fifty unsexed Ross broiler chicks were used for the study. The experiment was laid in a completely randomized design (CRD) in which BSSM were incorporated in the diets at 0, 10, 20, 30 and 40%, coded as Treatments 1, 2, 3, 4, and 5, respectively. Each treatment comprised of 3 replicates of 10 birds. Birds were housed in floor pens containing wood shavings as litter material. The diets and fresh drinking water were provided ad libitum throughout the eight weeks of the experiment. Data were analysed in statistical analysis system (SAS) package. Results revealed significant differences (p<0.05) in all the growth parameters measured except for initial body weight, feed conversion ratio and mortality. The packed cells volume (PVC) and white blood cells (WBC) were affected (p<0.05) by the treatment effect. Broiler chickens' health and productivity were not negatively affected by 30-40% BSSM inclusion in their diets, suggesting further research on improving sunflower seed using alternative treatment options
Indigofera Pellet Storage Time on Dry Matter Content, Organic Matter, Physical Properties and Palatability in Sheep
Full text linkOne of the protein sources of feed ingredients that contain high protein is I. zollingeriana. The abundant harvest of I. zollingeriana requires attention in the storage process. As forage, I. zollingeriana has bulky properties. This causes less efficiency in storage and transportation. Compaction of feed particles is one of the feed processing technologies to improve storage and transportation efficiency. The compaction process can be done by making pellets. The purpose of this study was to observe the interaction between the level of adhesive (cassava) and the shelf life of I. zollingeriana pellets on the content of dry matter, organic matter, physical properties, and palatability. The research was carried out with a nested design. The resulting data was tested with ANOVA. Indigofera zollingeriana was sun-dried for 3 days, grounded using a hammer mill, and given 10, 20, and 30% of the cassava as an adhesive. The pellets are dried in the sun to dry and put in plastic and sacks, and then the top is sewn using a sack sewing machine and stored in the feed warehouse for 0, 4, and 8 weeks. The I. zollingeriana pellets were stored for 0, 4, and 8 weeks. The results of the analysis showed that there was no interaction (P>0.05) between the adhesive level (cassava) and the shelf life of I. zollingeriana pellets. I. zollingeriana can be made into pellets with or without adhesive. Storage for up to 8 weeks did not affect the content of dry matter, organic matter, physical properties, and palatability.Keywords : pellets of I. zollingeriana, dry matter, organic matter, physical properties, palatabilit
THE EFFECT OF CLOSED HOUSE CAGE DENSITY ON MICROCLIMATE OF BROILER CHICKENS
No full textThe microclimate in the cage plays an important role in broiler productivity. Productivity is influenced by a good environment so that production will be maximized. The research was conducted in March-April 2023 in Pinggirsari Village, Arjasari District, Bandung Regency. The samples used were 52,500 broiler chickens of the Cobb CP 707 strain aged 0-32 days whose temperature, humidity, CO2 levels and NH3 levels in the cage were calculated. The cage used in this research is a closed house cage measuring 12x90 m divided into 6 partitions measuring 12 x 15 m, with each partition equipped with a feeding area and nipple drinker, fan feeder, baby chick feeder, and digital thermometer. The results of the study showed that cage density had a significant effect on temperature and levels of CO2 and NH3. Humidity had a real influence in the 4th and 5th weeks during maintenance on cage density. The average cage temperature is 25.17oC – 28.13oC, cage humidity is 70.41% - 82.24%, and CO2 levels are 594.13 ppm – 681.02 ppm. Density levels of up to 18 birds/m2 provide a good cage microclimate and are still optimal in industrial scale closed house cages. Keywords: broiler, cage density, microclimate
