Orientation by environmental geometry and feature cues in the green and black poison frog (Dendrobates auratus)
Anim Cogn. 2023 Sep 12. doi: 10.1007/s10071-023-01820-y. Online ahead of print.ABSTRACTThe ability to use environmental geometry when orienting in space reflects an animal's ability to use a global, allocentric framework. Therefore, understanding when and how animal's use geometry relative to other types of cues in the environment has interested comparative cognition researchers for decades. Yet, only two amphibians have been tested to date. We trained the poison frog Dendrobates auratus to find goal shelters in a rectangular arena, in the presence and absence of a feature cue, and assessed the relative influence of the tw...

Pinecone oil supplemented to multiparous sows from 107 days prenatal to 21 days postpartum improves reproductive performance and milk composition and affects serum parameters
In conclusion, supplementation of 400 mg/kg PO during late gestation and lactation contributed to greater offspring growth performance, possibly by enhanced milk quality and alleviated maternal stress. (Source: Journal of Animal Physiology and Animal Nutrition)

In ovo feeding of vitamins in broilers: A comprehensive meta ‐analysis of hatchability and growth performance
AbstractIn ovo feeding has been introduced as a cost-effective method to improve hatchability and broiler performance. Specifically, several studies have focused on the impact of vitamins. However, due to variations in experimental conditions across all trials, drawing general conclusions appears challenging. Therefore, we conducted a meta-analysis of 17 published papers, including a maximum of 134 sample size to evaluate the potential effects ofin ovo feeding of vitamins in broilers. Studies were retrieved by consulting scientific repositories such as Pubmed, Scopus, Scielo, Web of Science, and Google Scholar. A binary lo...

Supplemental impact of silymarin in growing pig diet on the growth performance, total tract digestibility, faecal microflora, faecal noxious gas emission and absorption rate in blood
AbstractThe research was done to examine the impact of dietary silymarin on growth performance, total tract digestibility, faecal microbial, faecal gas emission and absorption rate in blood of growing pigs. Experiment 1: a total of 140 growing pigs (24.47 ± 2.49 kg) were used in a 6-week trial. There were four dietary treatment groups (seven replicate pens/treatment, five pigs/pen) and treatment diets composed of corn, soybean meal (SBM), distille rs dried grains with solubles (DDGS), and rapeseed meal-based basal diets with 0%, 0.025%, 0.050% and 0.10% of micelle silymarin respectively. Experiment 2: A total o...

Is the relationship between body length and body mass consistent across habitats? A case study on Niphargus (Crustacea: Amphipoda)
Zoology (Jena). 2023 Sep 9;161:126120. doi: 10.1016/j.zool.2023.126120. Online ahead of print.ABSTRACTBody size is one of the main characteristics of any organism and influences various aspects of individual's biology. In animal ecology, it represents a key functional trait that can be quantified using different measures and is often used as a proxy for different organismal functions. The way we quantify body size is critical in any study using this measure alone or to scale other organismal traits. It is especially important in groups that act as model systems across different fields of biological research. One of such gr...

Polyomavirus-associated Disseminated T-cell Lymphoma in a Colony of Zebra Finches (Taeniopygia guttata)
Comp Med. 2023 Sep 11. doi: 10.30802/AALAS-CM-23-000011. Online ahead of print.ABSTRACTFour zebra finches in a closed research colony presented with variable clinical signs, including masses, skin lesions,shivering, and/or ruffled feathers. These birds were not responsive to treatment efforts; 3 died and one was euthanized. All4 were submitted for necropsy to determine the cause of the clinical signs. Gross necropsy and histopathologic findings fromall birds resulted in a diagnosis of round cell neoplasia in multiple organs, including the skin, liver, kidney, and reproductivetract, with intranuclear inclusion bodies in the...

Isolation and Characterization of a Novel Alpha-Hemolytic Streptococcus spp. from the Oral Cavity and Blood of Septicemic Periparturient Immunodeficient Mice
Comp Med. 2023 Sep 11. doi: 10.30802/AALAS-CM-23-000020. Online ahead of print.ABSTRACTMISTRG is an immunodeficient mouse strain that expresses multiple human cytokines that support hematopoietic stem cell maintenance and myelopoiesis. While establishing a breeding colony of MISTRG mice in a dedicated barrier room, 6 cases of death or disease occurred in pregnant or postpartum mice. Clinically, this manifested as hunched posture, dyspnea, and 1 case of emaciation with ataxia. Pathologic analysis of 7 mice revealed multisystemic necrosuppurative inflammation variably affecting the uterus and placenta, joints, meninges, inne...

Role of the placenta in developmental programming: Observations from models using large animals
Anim Reprod Sci. 2023 Aug 30;257:107322. doi: 10.1016/j.anireprosci.2023.107322. Online ahead of print.ABSTRACTDevelopmental programming, which proposes that "insults" or "stressors" during intrauterine or postnatal development can have not only immediate but also long-term consequences for healthy and productivity, has emerged as a major biological principle, and based on studies in many animal species also seems to be a universal phenomenon. In eutherians, the placenta appears to be programmed during its development, which has consequences for fetal growth and development throughout pregnancy, and likewise has long-term ...
