Kitten is the earliest stage of a cat’s 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.

Respiratory distress syndrome (RDS) or hyaline membrane disease is the most frequent cause of respiratory failure and mortality in preterm infants. As a result, many infants are brought to a neonatal intensive care unit (NICU). There may also be other factors that affect the incidence rate of RDS as well. Our research goals are to find out the incidence rate of RDS among three preterm groups and its related factors. In a cross-sectional-descriptive analytical study, newborn data was gathered and assessed by using hospital medical records. One hundred forty-two preterm infants with gestational age ≤ 36 weeks were hospitalized in the NICU. All participants were divided into three groups: extremely preterm ( 28 weeks), very preterm (28 to 32 weeks), and moderate-to-late preterm (32 to 36 weeks). The frequency of RDS and some related factors were compared among three groups. Finally, we analyzed the relationship between variables by SPSS statistics software version 19. The level of significance was considered P 0.05. Respiratory distress syndrome was observed in 64.68% of all participants; RDS is more common in infants within 28-32 weeks of gestation (81%), while infants with 28 weeks of gestation and 33-36 weeks of gestation have lower rates (50% and 52 Our study shows a positive correlation between birthweight and RDS as well as between birthweight and gestational age. (P value: 0.001, 0.003). Infants between 28 to 32 gestational age have a higher risk of RDS. The risk of RDS also increases in low birth weight and male infants.

Using an online questionnaire, this study evaluated the profile of a Brazilian population’s food handling practices in the home environment. The questionnaire, containing questions about domestic behavior in terms of hygiene and food handling, was built and available through social media sites. Information about the participants’ profiles, their food prepreparation, food preparation, and food post-preparation practices, and the occurrence of foodborne diseases (FBDs) was included in the questionnaire. A total of 701 responses were obtained. The interviewees included 78.31% female participants and 21.68% male participants, with an average age of 31.2 years. Nearly all (94.3%) had a complete or incomplete higher education. In the pre preparation stage, the participants evaluated the shelf life (97.28%) and storage temperature (44.79%) of the products while purchasing them. Regarding food handling practices, only a few participants washed the food packages before storing them (31.95%) or removed hand jewelry or other adornments when washing food (61.48%). Most participants washed their hands (91.58%) and washed vegetables (99.28%). But a group of interviewees reported washing raw meat (27.81%) before preparing it. Cutting surfaces such as plastic (50.36%) and glass (49.36%) tops were the most prevalent in the study. Most respondents did not know how long they had been using their cutting boards (67.62%) and mentioned using the same surface to handle both raw and ready-to-eat products (84.17%). As for the preparation, most interviewees declared they did not check the food temperature during preparation (86.31%), ignoring the ideal cooking temperature (88.26%). Regarding the occurrence of FBDs, 79.17% of the interviewees reported having suspicious clinical signs associated with contaminated foods and 65.59% did not seek medical help. Thus, the participants demonstrated ignorance about adequate practices for food safety in the home environment, highlighting the need to conduct health education programs within the Brazilian population.

The objective was to evaluate the fermentation profile, aerobic stability, chemical composition, and mineral content of silages of mango combined with cocoa pod husk meal. A completely randomized design was adopted, including four levels (65, 70, 75, and 80%) and five repetitions, totaling 20 experimental silos that were opened after 90 days of sealing. Increasing mango levels in the silages increased the dry matter recovery, total carbohydrates, and fraction B2 of carbohydrates, and reduced gas losses, dry matter, and mineral matter. The quadratic effect was found for pH, buffering capacity, potassium, boron, iron, and nitrogen fractions A and B1 + B2. Using unconventional products such as mango combined with cocoa pod husk meal for silage making can reduce the cost of food supplementation for ruminants, and the environmental contamination.

The objective of this study was to estimate (co)variances and genetic parameters and to predict genetic trends for weight at 120 (W120), 210 (W210), 365 (W365), and 450 (W450) days of age in Nelore cattle raised in the northern region of Brazil. The database comprised records of 30,387 animals born between 2000 and 2013 in the Brazilian North. Estimates were calculated by the Restricted Maximum Likelihood (REML) method, in single- and multi-trait analyses in an animal model. Heritability as obtained using single- and multi-trait models for W120 (0.22 and 0.31), W210 (0.20 and 0.34), W365 (0.51 and 0.51), and W450 (0.49 and 0.51) indicated moderate to high magnitudes, with the possibility of genetic selection and incorporation into the herd. Genetic correlations between growth traits were favorable, ranging from 0.78 to 0.96. Genetic trends for W120 and W210 varied largely, from -0.31 to 4.68 and -0.53 to 7.62 kg/year, respectively. Smaller fluctuations were observed in genetic trends for W365 and W450, which ranged from -1.08 to 10.90 and -1.29 to 12.51 kg/year, respectively. Selection for W365 and W450 proved to be the criterion of choice for Nelore herds raised in the region; however, it may compromise adult performance because of higher costs and time for production. A thorough analysis of mattings is recommended to allow the selection of earlier-developing animals.

This study evaluated (a) the efficacy of an association between injectable antibiotic therapy and sealant (ATBS) on milk yield (MY), somatic cell count (SCC), and prevalence of intramammary infections (IMI); and (b) the efficacy of gonadotropin-releasing hormone (GnRH) on follicular cyst (FCs) resolution (cyclicity at the 45th day in milk; DIM) and cumulative pregnancy rate (CPR) in heifers submitted to a lactation induction protocol (LIP). A total of 114 crossbred (Holstein × Jersey) heifers, with 34.7 ± 4.8 months and 439 ± 56.35 kg were submitted to LIP. On the 5th day of the LIP, the heifers were assigned to (i) ATBS (n = 57) with 7 mg/kg of norfloxacin associated with sealant and (ii) Control 1 (n = 57; CONT1) with no treatments. Lactation began on the 21st day of LIP and the 15th DIM, FCs were diagnosed and 106 heifers were randomized into two treatment groups with 53 heifers each: (i) GnRH (5 mL injectable GnRH) and (ii) Control 2 (CONT2; no treatment). Of the 114 heifers initially induced, 83.33% (n = 95) responded to LIP with an average MY of 15.19 kg/milk/day during 22 weeks of lactation. In the first 14 DIM, the IMI prevalence was 18% and 28% for heifers ATBS and CONT1 treated, respectively. Additionally, coagulase-negative Staphylococcus was the most frequently isolated group of pathogens. Mammary quarters that received ATBS treatment had a lower risk of IMI and SCC than CONT1. The cyclicity at 45 DIM was 68% (ATBS) and 35% (CONT1), and 57% and 46% for animals in the GnRH and CONT2. CPR was 60% in the ATBS group and 89% in CONT1, but GnRH treatment did not affect the CPR. In conclusion, LIP was effective in stimulating MY in heifers, and the IMI prevalence decreased with ATBS treatment. Also, the use of GnRH did not affect the FC regression, cyclicity at 45 DIM, and CPR.

Objectives: The herbicide glyphosate, a pesticide used in agriculture to control weeds, both in food crops and in other agricultural areas, has been identified as an endocrine modulator through the inhibition of aromatase activity and the activation of estrogen receptors. The present study examined the effects of a glyphosate-based herbicide (Roundup® (GLY-BH) on sexual dimorphism of rats after perinatal exposure to low and high GLY-BH in males and females offspring. Methods: Two groups of pregnant rats were treated with two doses of GLY-BH (50 or 150 mg/kg) from day 15 of gestation (GD15) to postnatal day 7 (PND7). Play fighting behavior was observed at the juvenile stage and during social and sexual behaviors in adulthood. Results: Perinatal GLY BH exposure reduced male and female body weight at 28, 75, and 90 days of age. The play fighting behavior was decreased in both sexes, but female rats were more affected. The sexual behaviors were reduced only in females. Conclusions: Perinatal exposure to both doses of GLY-BH promoted sexually dimorphic effects in both juvenile and adulthood stages. These effects were attributed to the inhibition of aromatase activity induced by exposure to GLY-BH in the perinatal period.

Sedative and antinociceptive effects of two anesthetic protocols in black-tufted marmosets were compared in this study. Twenty-six marmosets underwent chemical immobilization for physical examination, blood sampling, tattooing, and microchipping. Animals were randomly treated with S-(+)-ketamine (10 mg/kg) and midazolam (1 mg/kg) (KM) or fentanyl (12.5 µg/kg) and droperidol (625 µg/kg) (FD) given by intramuscular injection. Heart and respiratory rates were recorded. Sedation, antinociception, muscle relaxation, posture, auditory, and visual responses were evaluated using a scoring system. Sedation in KM was achieved faster (p < 0.001) and lasted for a shorter period of time (p = 0.0009). KM was similar to FD in its cardiorespiratory effects, auditory and visual responses. Both protocols promoted adequate sedation to allow manipulation. Animals in KM assumed lateral recumbency while animals in FD maintained a quadrupedal posture during evaluation. FD produced less intense sedation and muscle relaxation but a higher degree of antinociception compared to KM and is suitable for procedures that require analgesia in black-tufted marmosets.
