“…This value was somewhat similar to that obtained by de Souza et al, 3.51 ± 1.6 ppm ( 30 ), but it was found below (4.3–4.53 ppm) that described by Faria et al ( 32 ). In another study, by de Souza et al, Cu values of 5.61 ± 1.38 ppm were recorded ( 11 ). Copper has a very specific role in the growth of the hoof, as it is essential to build the keratin bridges present in the hoof.…”

“…The K levels determined (3,416 ± 3,270 μg/g) were higher than those mentioned by Sargentini et al (1,690 ± 112 ppm) ( 24 ) and de Souza et al (460 ± 425 ppm) ( 31 ). With regard to Mg, values of 181 ± 98 μg/g were obtained, while in mules and donkeys, de Souza et al ( 11 ) indicated values of 840 ± 922 ppm and 1,178 ± 855 ppm, respectively.…”

“…If Cu is deficient, enzyme activity decreases, and the structural bridge is compromised. Ultimately, it is likely that the growth of these protein bridges will be affected, and in turn, this causes the hoof to show cracks from the growth ( 11 ).…”

“…Minerals comprise approximately 4% of body weight and are an essential part of the horse's diet as they help to metabolize proteins, fats, and carbohydrates; aid muscles and nerves to function properly; maintain the acid-base balance of body fluids; and are essential components of each enzyme required for metabolic functions (5). Horses require at least 15 different mineral elements, and some of these are required in relatively greater amounts such as calcium (Ca), phosphorus (P), sodium (Na), potassium (K), chlorine (Cl), magnesium (Mg), and sulfur (S), while microminerals such as iron (Fe), copper (Cu), zinc (Zn), manganese (Mn), and selenium (Se) are needed for keratinization in the living part of the hoof (10); however, with regard to microminerals, Zn and Cu are also important for improving hoof quality (11). That is why equine hoof characteristics such as its tensile strength, wear, and integrity, are associated with the chemical composition of the hoof and clearly depends on dietary nutrients (10)(11)(12).…”

Preliminary Study on the Connection Between the Mineral Profile of Horse Hooves and Tensile Strength Based on Body Weight, Sex, Age, Sampling Location, and Riding Disciplines

Hoof mineral profile is important as it could affect locomotion. Factors such as body weight, sex, age, and riding disciplines affect hoof mineral profile. In Mexico and globally, studies are needed on the characterization of mineral profile of hooves and tensile strength, as this could help to prevent overgrowth or microfractures. Therefore, in the present survey, 165 samples of equine hoof cuttings from different sex, ages, breeds, and riding disciplines from different regions of Mexico were analyzed for their mineral composition, and a universal testing machine was used to measure tensile strength. More than half of the samples were from males (63%) and aged 3 to 5 years (52%). Most samples were obtained from horses used for reproduction (36%) and working (29%) purposes. The most preponderant minerals were K (3,416 μg/g), Na (2,242 μg/g), and Ca (631 μg/g). Tensile strength ranged from 1.2 to 45 N. Females had higher (P < 0.05) amounts of Zn than males. Animals younger than 3 years old have lower (P < 0.05) levels of Na than those between 3 and 5 years old. Horses used for reproduction had lower (P < 0.05) Mg concentrations than animals used for running and working. Tensile strength was similar between demographic characteristics. Horses from Santa Gertrudis military ranch had higher (P < 0.05) levels of Ca, Se, and Na compared with horses from other sampling location. Copper was higher (P < 0.05) in horses from racecourse. Potassium was higher (P < 0.05) in horses from the Presidential General Staff. Overall, there was no evident connection between sex, ages, breeds, and riding disciplines from different regions of Mexico and the mineral composition of the hoof or its tensile strength. Further research should focus on the relation on specific feeding regimes, horse individual characteristic, hoof mineral contents, and tensile strength.

У вітчизняних літературних джерелах на сьогодні практично відсутня інформація щодо анатомічних та фізіологічних особливостей копит віслюків, їхніх відмінностей від копит коней, ме-тодів розчистки та перебігу патологічних процесів у ділянці копита. Через популяризацію утриман-ня віслюка не тільки як сільськогосподарської тварини, а і як домашнього улюбленця, у зарубіжних науковців зріс інтерес до цих тварин, а оскільки вони також потребують догляду, то й до особливо-стей анатомії й фізіології, зокрема копит віслюків. Огляд зарубіжних літературних даних показав, що всі структурні елементи копита віслюків мають анатомічні та фізіологічні відмінності від копит у коней. Серед таких відмінностей варто відмітити: фронтальна форма копита, форма опорної поверхні копита, інші проміри кутів копита, розмір та положення кісток копита, великі розвинені пружні частини копита, інше співвідношення розмірів структур копита та багато іншого. Зважаючи на особливості в анатомічній будові копита при розчистці віслюків спеціаліст повинен відходити від наявних класичних методів, які застосовуються для розчистки в коней та досконало володіти технікою розчистки саме у віслюків. Віслюки на відміну від коней здатні трива-лий час «приховувати» існуючі проблеми з копитами, а клінічні ознаки з’являються вже коли стан копита надто складний, а лікування та реабілітація будуть тривалими та економічно місткими. А отже, власникам та ветеринарам, що мають справу з віслюками, необхідно напевно знати, яким має бути копито віслюка в нормі та чим воно відрізняється від копита коня. Цей огляд має на меті пояснити щодо наявних відмінностей в анатомічній будові копит віслюків та коней. Проведений аналіз є надзвичайно корисний та має як теоретичне, так й практичне значення, адже дає змогу лікарям ветеринарної медицини та спеціалістам, які проводять розчистку копит у тварин здійсню-вати цю маніпуляцію максимально правильно, що сприятиме кращому догляду за кінцівками віслюків, а отже, й за твариною загалом.

Filter-feeding has been present for hundreds of millions of years, independently evolving in aquatic vertebrates' numerous times. Mysticete whales are a group of gigantic, marine filter-feeders that are defined by their fringed baleen and are divided into two groups: balaenids and rorquals. Recent studies have shown that balaenids likely feed using a self-cleaning, cross-flow filtration mechanism where food particles are collected and then swept to the esophagus for swallowing. However, it is unclear how filtering is achieved in the rorquals (Balaenopteridae). Lunging rorqual whales engulf enormous masses of both prey and water; the prey is then separated from the water through baleen plates lining the length of their upper jaw and positioned perpendicular to flow.Rorqual baleen is composed of both major (larger) and minor (smaller) keratin plates containing embedded fringe that extends into the whale's mouth, forming a filtering fringe. We used a multimodal approach, including microcomputed tomography (µCT) and scanning electron microscopy (SEM), to visualize and describe the variability in baleen anatomy across five species of rorqual whales, spanning two orders of magnitude in body length. For most morphological measurements, larger whales exhibited hypoallometry relative to body length.µCT and SEM revealed that the major and minor plates break away from the mineralized fringes at variable distances from the gums. We proposed a model for estimating the effective pore size to determine whether flow scales with body length or prey size across species. We found that pore size is likely not a proxy for prey size but instead, may reflect changes in resistance through the filter that affect fluid flow.
