Kitten is the earliest stage of a cats life, starting from 0 6 months old. As the golden age of a human baby in their first 1000 days of life, a kitten is the golden period for cats to grow and explore the environments. People tend to adopt cats at this stage as it is easier for them to shape and understand the characteristics of their cats. Therefore, understanding the behaviors of cats during the kitten period is fundamental. This study observed the behaviors of two pet kittens at 13 weeks of age when they roamed around the urban backyard. An ethogram was designed to record the duration of states (in second) and the frequency of events (per observation) of all behaviors. During the assessments, both kittens dominantly performed exploratory behaviors. They tended to explore the environment by sniffing ground, climbing trees, staring at birds, and walking around the backyard. These behaviors could be seen more often than their playing behaviors (object play and social play). In conclusion, this study supports the view that during the late socialization period (9-16 weeks), kittens seem to show the intense exploration of the environment as part of the development of predatory behavior or hunting skills in wild nature settings.

The chicken farming industry in Indonesia cannot be separated from the use of antibiotics as a curative effort in controlling the disease. Its use is either via injection, soaking, or as a feed additive (growth promoter) mixed in feed. Inappropriate use of antibiotics causes allergic reactions or resistance and the possibility of causing poisoning, residues in livestock tissues or organs that are harmful to human health when consuming them. This study aimed to determine the antibiotic residues in eggs and the level of knowledge of livestock workers on the use of antibiotics in livestock. The detection of antibiotic residues was conducted using the agar plate diffusion method by Kirby Bauer with the disk diffusion technique using Escherichia coli and Salmonella sp. As indicator bacteria. The results were analysed using a qualitative descriptive approach. The samples were 76 eggs taken from the Regional Technical Implementation Unit of the Non-Ruminant Livestock Center of the Aceh Livestock Service in Blang Bintang and Saree Aceh Besar. Chloramphenicol antibiotic was used as a test medium and as control by calculating the diameter of the inhibition zone formed on MHA media. furthermore, a cross-sectional study design was used and questionnaires were distributed to 14 livestock officers to understand the knowledge of officers on the use of antibiotics in livestock by using google form. The data were analyzed using the chi-square test through the SPSS 22.0 program. The results showed that the eggs and feed samples were negative from antibiotic residue. There was no relationship between feeding and antibiotic residues in eggs and laying hens feed. However, only 35.7% of officers had good knowledge about proper antibiotic usage. This means continuing awareness to the officers regarding the use of antibiotics either for treatment of diseases or as feed promoter are essential.

A cross-sectional study was conducted among commercial pig farmers in the Ejisu Municipality to investigate reproductive performance, piglet mortality, and reproductive health problems on their farms. Questionnaires designed to obtain information on reproductive performance and reproductive health problems were administered to a total of 50 randomly selected pig farmers. Three farms were randomly selected to monitor farrowing and pre-weaning piglet mortality. The farrowing records of a minimum of 10 sows on each farm were taken, and the piglets followed up to the point of weaning by six weeks. Records of piglet mortalities and their causes were retrieved from farm records or post mortem reports. The mean litter size, stillbirth per litter, piglet birth weight (Kg), weaning to estrus interval, and gestation period were 9.5 1.4, 1.6 0.2, 1.0 0.1, .71.0 days, and 115.1 2.6 days, respectively. The pre-weaning mortality (%) at day 42 was 18.7 and ranged from 7.3-28.3. Within the first two days post farrowing, mechanical crushing (8.9%) of piglets by sows and piglet starvation (7.2%), while diarrhea (2.5%) and piglet anemia (1.5%) accounted for mortalities within the first two weeks of life. Reproductive health problems by frequency of occurrence included mastitis (23%), agalactia (18%), stillbirths (18%), repeat breeders (14%) and dystocia (14%). The study concluded that the reproductive performance of sows was satisfactory, while pre-weaning piglet mortality was high. It is recommended to intensify extension education on the management of piglets after farrowing.

Many countries have imposed regulations relating to concerns that hide contamination will affect the cleanliness of abattoirs. However, South Korea has not indicated any clear criteria. The purpose of this study is to use surrogate bacteria to measure the contamination in abattoirs caused by contaminated cattle hides. The swab contact method and plate count method are used. Surrogate bacteria are found in most internal environments after the final process. These surrogates remained on the carcass even after the final washing process. This paper is the first study in South Korea that use surrogate bacteria to analyze contamination levels in abattoirs.

The objective of this study was to identify risk factors for repeat breeder dairy cows and their impact on reproductive performance. The characteristics of 1,504 cows, including their peripartum health, nutrition, production, and reproduction, were collected. Cows with metabolic disorder were significantly more likely (odds ratio [OR], 2.47; p less than 0.001) and cows with clinical endometritis tended to be more likely (OR, 1.35; p less than 0.1) to become repeat breeders than cows without metabolic disorder and clinical endometritis, respectively. Cows initially inseminated more than 80 days after calving were less likely (OR, 0.78; p less than 0.05) to become repeat breeders than cows initially inseminated ≤ 80 days after calving. As a result, repeat breeding in dairy cows resulted in a 90 day longer (p less than 0.0001) mean interval from calving to pregnancy. In conclusion, postpartum metabolic disorder, clinical endometritis, and a short interval from calving to initial insemination were risk factors for repeat breeder dairy cows, resulting in a severely impaired reproductive performance.

This study investigated dexamethasone (DXM) residues in the milk from intramuscularly dosed dairy cows and established the withdrawal time (WT) of DXM in milk. Eighteen healthy Holstein cows were injected with 20 (DXM-1) or 40 mL (DXM-2) of a drug containing 1 mg/mL of DXM. After administering DXM, milk samples were collected from all cows at 12-hour intervals for five days. The DXM residue concentrations in milk were determined by liquid chromatography-tandem mass spectrometry. The correlation coefficient of the calibration curve was 0.9966, and the limits of detection and quantification (LOQ) were 0.03 and 0.1 μg/kg, respectively. The recoveries were 97.0% to 104.0%, and the coefficient of variations was less than 7.22%. After treatment, DXM in DXM-1 was detected above the LOQ in two milk samples at 36 hours and below the LOQ in all milk samples of DXM-2 at 48 hours. Using the WT calculation program WT 1.4, the withdrawal periods of DXM-1 and DXM-2 in milk were established to be two days. In conclusion, the developed analytical method is sensitive and reliable for detecting DXM in milk. The estimated WT of DXM in bovine milk is shorter than the current milk WT recommendation of three days for DXM in lactating dairy cows.

This study was aimed to evaluate the prophylactic anti-glaucoma effect of topical 5% betaxolol (BTX) and 2% dorzolamide (DRZ) on the second eye in dogs with unilateral primary angle closure glaucoma (PACG). Medical records of 60 dogs with unilateral PACG who received prophylactic anti-glaucoma eyedrops in the second eye, from 2016 to 2021, were reviewed. The prophylactic effects of BTX were maintained on 28/60 (46.7%) eyes until last visit and BTX failure was observed on median 510 (range, 53-1,927) days in 32/60 (53.3%) eyes. After DRZ instillation in BTX failure eyes, the prophylactic effects were extended at median 610 (range, 157-2,270) days in 21/32 (65.6%) eyes. DRZ failure eyes (17/21, 81.0%) eyes required chemical ablation or surgical intervention due to uncontrolled intraocular pressure. The duration of prophylactic effects was decreased with aging (R2 = 0.334, p = 0.006). The predominant breeds were Shih-Tzu (41.9%) and American Cocker Spaniel (30.6%) with no significant differences in survival curves (p = 0.210). The average prophylactic effects of BTX persisted more than 1.5 year and could be selected the first prophylactic eye drop in unilateral PACG. Also, early surgical intervention should be considered in prophylactic medications failure cases.

5-Fluorouracil, doxorubicin, and vincristine are chemotherapy agents used to treat various cancers, such as breast cancer and lymphoma for decades, and their effects on cancer have been proven. On the other hand, these anti-cancer drugs cause fatal side effects, including immunosuppression. This study investigated whether sonicated Bordetella bronchiseptica bacterin (B. bronchiseptica) can attenuate the immunosuppression of spleen cells induced by these chemotherapy agents and which subsets of spleen cells were affected. B. bronchiseptica increased the metabolic activity of spleen cells treated with 3 anti-cancer drugs. Cell death analysis using Annexin V/propidium iodide showed that B. bronchiseptica markedly decreased the death of spleen cells. The subsets of spleen cells were analyzed by flow cytometry using a surface marker-specific antibody. B. bronchiseptica increased nitric oxide production in the spleen cells treated with anti-cancer drugs (p less than 0.0001). Despite the pharmacological effects of anti-cancer drugs, many patients suffer from the fatal side effects of immunosuppression. This study provides valuable information on how to overcome chemotherapy-induced immunosuppression.

With the increasing population of companion dogs, the social cost derived from their behavioral problems is increasing. Therefore, it is important to understand the environment to provide experience for dogs via interactions with their owners to prevent and solve these problems. The parenting behavior of dog owners as an environmental factor has a profound impact on the behavior development of dogs, as does the parenting behavior on children. Therefore, this study aimed to develop a scale to assess the dog owner’s parenting behavior. Exploratory factor analysis involving 300 participants resulted in a scale with four subscales, Positive Education, Involvement of Socialization, Intimacy, and Stable Responses, and 19 items. Confirmatory factor analysis was then performed to verify its reliability and validity. The result of parenting behaviors assessed by this scale was significantly different between a group with dogs with problematic behavior (n = 141) and those without (n = 159). Overall, a dog owner’s parenting behavior involves affection and control aspects, but the role required specifically in the control aspect is distinguished from the parenting behavior with children. The findings in the present study will provide dog owners with effective education that will help prevent dogs from developing behavioral problems.

This study reports the efficacy of the vasodilator sodium nitroprusside (SNP), for treatment of acute cardiogenic pulmonary edema in dogs. For this study, the patients were divided into the SNP only treatment group, the SNP, furosemide and dobutamine treatment group, and non-SNP treatment group. Seven dogs, 6 dogs and 2 dogs were favorable responders in SNP only group, group with SNP, furosemide and dobutamine and non-SNP treatment group, each. The results of this study suggest that SNP can be an effective alternative therapy for dogs with acute cardiogenic pulmonary edema.
