An Overview of the Rock Art of AlUla: Tracing Changes in Content and Form Across 12,000 Years of Human History

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Between 2018 and 2021, the Identification and Documentation of Immovable Heritage Assets (IDIHA) Project recorded over 19,000 rock art panels in the AlUla (al‐‘Ulā) region of north‐western Saudi Arabia. This study presents a chronological assessment of the corpus, drawing on superimpositions, datable motifs, inscriptions, and varnish formation,

Trace Element Patterns in Juvenile Wild Chimpanzee Dentitions

open access: yesArchaeometry, EarlyView.
ABSTRACT Trace elements are used to infer mammalian early‐life diets, environmental toxins, dispersal patterns, stress histories, and weaning ages. Here, we employ laser ablation‐inductively coupled plasma‐mass spectrometry (LA‐ICP‐MS) to reveal elemental patterns in our closest living relatives, chimpanzees.

Animal Production Performance and Herd Management in Suckling Farms on Réunion Island

open access: yesRevue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 2008
In Réunion, because of the insularity and the small size of farms, improving cattle farm productivity involves increas­ing technical management aspects. To analyze relationships between herd management practices and animal perform­ances, a survey was conducted in ten suckling farms, located in the Highlands, from 1999 to 2002.

Shaping Future Children, Sex Selection, and “Normal” Human Capacities

open access: yesBioethics, EarlyView.
ABSTRACT If we think that parents have an obligation to have a healthy child then we need to know what counts as healthy, when male and female children are born with very different capacities. If we give up on the idea that our obligations to use technologies of genetic selection are discharged once we try to secure the birth of a healthy child, as ...

Muscarinic agonists for schizophrenia: Bridging preclinical evidence and clinical enthusiasm

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Antipsychotic drugs targeting dopamine receptors have been used to treat schizophrenia for decades, primarily alleviating positive symptoms such as hallucinations and delusions. However, they provide limited benefit for cognitive and negative symptoms—major contributors to poor outcomes—and are frequently associated with significant side ...

Suckling and allosuckling behavior of dairy calves in indoor dam-rearing systems

open access: yesFrontiers in Veterinary Science
An important element in dairy cow-calf contact (CCC) systems is to ensure sufficient milk intake by calves. However, little is known about possible changes in suckling behavior during suckling periods for calves up to 15 weeks old, and the prevalence of ...

Evaluating the Predictive Value of Estimated Breeding Values of Piétrain Sires for Uniformity and Survival in Their Crossbred Progeny

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT High litter sizes in pigs are associated with lower birth weights and increased within‐litter variation, which poses challenges to pig farming. Improving piglet uniformity and survival via genetic selection of terminal boars could be a strategy to enhance these traits.

Impact of birth weight and daily weight gain during suckling on the weight gain of weaning piglets [PDF]

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia
This study evaluated the effect of birth weight and weight gain during the suckling phase on the piglet daily weight gain during the nursery phase (21-61 days of age). Piglets (n= 534) derived from 55 first-parity sows were weighed at birth, weaning, and

Genetic Determination of Maternal Behaviour in Pigs

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In sows, maternal behaviour is a commercially important trait which affects sow and piglet welfare and the quality and safety of human‐animal interactions, especially if free farrowing of sows without crates is in place. The aim of this study was to evaluate maternal behaviour and to estimate its quantitative genetic parameters in Swiss ...
