    Mare milk, compared to the milk of other animal species used for dairy purposes, is distinguished by a wealth of bioactive substances conferring health benefits. Mare milk positively affects the human immune system and digestive system. It is rich in nutrients that have a beneficial effect on the skin and protect its cells against oxidative stress. The aim of the survey was to investigate consumer awareness of the alternative use of mare milk. The survey was conducted among students from four fields of study (bioengineering of food, dietetics, agriculture, and animal husbandry) and people with no connection to agriculture. In total, responses were obtained from 200 people. Fifty-one per cent of respondents were unaware that horses are used for dairy purposes. Mare milk is most often (60% of respondents) associated only with food for foals. The respondents’ awareness of the chemical composition of milk was low (37%). The main food product made from mare milk that was familiar to the respondents (70%) was kumis.

    Analysis of equine feeding systems in selected equestrian centers and stables
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2017) Janocha, Alina; Kryszak, Katarzyna; Różewicz, Marcin; Department of Animal Nutrition and Feed Management, Siedlce University of Natural Sciences and Humanities; Department of Animal Nutrition and Feed Management, Siedlce University of Natural Sciences and Humanities; Department of Animal Nutrition and Feed Management, Siedlce University of Natural Sciences and Humanities
    The aim of the study was to study the expertise and awareness of Polish horse owners in terms of equine nutrition and prevention of gastrointestinal tract problems, as well as to overview the applied feeds. Knowledge on the structure and functioning of equine digestive system and digestion processes is essential if we want to plan good nutrition schemes, especially for sport horses. Having a profound knowledge on horse feeding and nutrition, the owner may avoid many problems with the horse’s fitness and reduce the risk of digestive disorders. Horses are animals that basically feed on pasture. However, the work they perform for humans, which is associated with intense physical activity, requires additional energy and nutrients. Most difficult is the nutrition of performance horses, which requires proper determination of energy needs at the given level of training load, as well as adequate mineral-vitamin supplementation that will meet the needs of the horse. The entire consistent nutrition system should be treated with utmost care and consideration, since it is the key factor influencing the health status of the horse.

    Influence of the Season of the Year on the Quality of Milk Purchased by Dairies
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2019) Kot, Emilia; Wójcik, Ewa; Kryszak, Katarzyna; Institute of Bioengineering and Animal Breeding, Siedlce University of Natural Sciences and Humanities, Poland; Institute of Bioengineering and Animal Breeding, Siedlce University of Natural Sciences and Humanities, Poland; Institute of Bioengineering and Animal Breeding, Siedlce University of Natural Sciences and Humanities, Poland
    The aim of the study was to assess the effect of the calendar month on the quantity of milk purchased by dairies and to assess the chemical quality of milk based on analysis of its content of protein, fat, casein, and urea, as well as its SCC. Analysis of milk purchased in individual months showed that the most milk was purchased in June and the least in December. Assessment of the chemical composition of raw milk revealed that it contained on average 4.18% fat, 3.23% protein, 2.61% casein, and 222.92 mg/l urea, with a SCC of 246.67 1000/ml. The differences between means for individual months were statistically significant.
