The evolution of the investment in exaggerated secondary sexual traits is a topic of great interest for scientists. Despite antlers in the family Cervidae being one of the most interesting allometric structures, the nature of the relationships between antler and body size, and the influence of physiological factors driving the evolution of these characters, still remain unclear. In this paper, I examine these relationships in depth using the largest sample size ever studied (43 species). Under the hypothesis that antler growth may be limited by skeleton size as this process requires the allocation of huge amounts of mineral resources to the antlers, skeleton-related variables may more accurately explain these allometric relationships. The existence of physiological constraints should therefore be more clearly highlighted when studying the relationships between body size variables and the relative investment in the antler (measured as length or mass of antler per kg of skeleton). Results show that antler length is best described as being linearly related to head-body length rather than other measurements of size, and antler weight has a quadratic relationship with body mass. However, the relative investment in antler length (related to skeleton mass) is independent of body size variables, while the relative investment in antler mass has a quadratic relationship with shoulder height. The results obtained for antler mass reflect the existence of physiological constraints in the evolution of antlers, which are greater for larger sized species. On the other hand, the evolution of antler length may be linked to other factors, most probably sociobiological and biomechanical ones.

Factors affecting antler growth period and casting date in red deer

Jose Angel Gomez, Javier Perez-Barberia, Andres Jose Garcia, Jamil Cappelli, Louis Chonco, Francisco Ceacero, Martina Perez-Serrano, Tomas Landete-Castillejos

Summary: Body weight, age, and antler weight have effects on the casting date and growth period of antlers. Heavier and older males cast their antlers earlier and grow them faster. The date of the end of antler growth also influences casting date, with longer growth period leading to later casting.

Influence of weather on the behaviour of reintroduced Przewalski's horses in the Great Gobi B Strictly Protected Area (Mongolia): implications for conservation

Anna Bernatkova, Ganbaatar Oyunsaikhan, Jaroslav Simek, Martina Komarkova, Miroslav Bobek, Francisco Ceacero

Summary: Weather patterns seem to influence the behavior of Przewalski's horse, with feeding behavior increasing in cloudy and windy conditions, and locomotion behavior being positively influenced by temperature and cloudiness. Increased social interactions were observed with higher temperatures and were more frequent in summer. Differences in behavior were found among the selected harems based on their origin and experience. These results are important for further management plans for the species, especially in the context of intensifying climate change and alteration of weather patterns.

Carcass and Offal Yields of Farmed Common Eland (Taurotragus oryx) Males, as Affected by Age and Immunocastration

Tersia Needham, Abubakar Sadiq Musa, Radim Kotrba, Francisco Ceacero, Louwrens Christiaan Hoffman, Nicole Lebedova, Daniel Bures

Summary: Common eland have untapped potential in meat production, but are currently undervalued. Immunocastration has no effect on slaughter performance, while age affects offal yields and muscle yields. Juveniles have higher primal cut yields and high-value meat ratio, while sub-adults have higher individual muscle yields.

Evidence of three distinct lactation stages in nursing gazelles: Implications on maternal behaviour assessment

Pavlo Fiialkovskyi, Jorge Cassinello, Karolina Brandlova, Francisco Ceacero

Summary: Studying suckling behaviour provides insights into parent-offspring conflict in mammals, but this information is often reported as a by-product of studying other types of suckling behaviour. This study analyzed filial suckling bouts to understand the decision-making process and found three distinctive behavioural stages in dorcas gazelles during the lactation period. Additionally, there was evidence of male-biased maternal investment and a compensational mechanism for different birth seasons.

Effects of immunocastration and supplementary feeding level on the performance and blood biochemical markers of farmed yearling fallow deer (Dama dama)

Veit Ny, Tersia Needham, Ludek Barton, Daniel Bures, Radim Kotrba, Abubakar S. Musa, Francisco Ceacero

Summary: Blood biochemical markers in cervids can indicate changes in physiology and environment, particularly in response to nutrient supplementation or hormone manipulation. Immunocastration is a more ethical method but remains unexplored in fallow deer. This study examines the effects of food supplementation and immunocastration on growth parameters and blood markers in yearling male fallow deer, showing that diet and immunocastration can influence body growth and blood biochemical markers. However, further research is needed to evaluate carcass performance under similar conditions.

Combined effects of supplementation of amino acids and immunocastration in first antler growth of farmed fallow deer (Dama dama)

Francisco Ceacero, Veit Ny, Radim Kotrba, Ludek Barton, Stipan Cupic, Daniel Bures, Jiri Turek, Martina Komarkova, Tersia Needham

Summary: Amino acid supplementation and immunocastration are two husbandry practices that have attracted increasing attention in the deer farming industry. They have positive effects on body growth and product quality, but may interfere with antler growth due to hormonal regulation. This study evaluated the combined use of both practices and found that amino acid supplementation had limited impact on antler growth, while immunocastration had significant effects on antler composition.

Summary: Analyzing social networks is a powerful tool for understanding the ecology of social species. This study found that there are significant differences in social network connectivity between wild-born and captive-bred Przewalski's horses, with wild-born individuals having stronger network connections. This trend supports the need for time in newly released groups of Przewalski's horses to display the typical social behavior patterns of wild-born individuals.

Potential benefits of amino acid supplementation for cervid performance and nutritional ecology, with special focus on lysine and methionine: A review

Veit Ny, Tersia Needham, Francisco Ceacero

Summary: Deer farming is an important industry, and studies have shown that amino acid supplementation can have positive effects on various production factors and overall performance of captive-bred cervids. However, the supplementation should be used with caution in high protein rations and during winter to avoid the accumulation of internal fat. Further research is needed to explore the potential effects on milk production and antler cycle regulation.
