Abstract:

Many wildcat species are threatened with extinction, rare or vulnerable due to habitat destruction and poaching. In addition, Ankara and Van domestic cat species originating from Türkiye are in danger of extinction and are under protection. Thus, the requirement for assisted reproductive techniques in b oth domestic and nondomestic cat species has been increasing in recent years. Assisted Reproductive Technologies (ART) such as in vitro maturation, in vitro fertilization, embryo transfer, and cloning in domestic cats (Felis catus) provide a useful and suitable model for the conservation of end

Abstract:

Knowledge about forming of sex cells, fertilization and pregnancy is basis for biotechnological effect on reproduction. Beside artificial insemination which is regularly used in practice in Serbia, embryo transfer is method which will probably have wide application, since it enables good performances of male heads and improvement with genetic material of selected female heads. Method is especially useful in selection and breeding of cattle and horses, since in previous agricultural practice, number of offspring from single female head was relatively small.

Abstract:

Breeding by natural mating is ideal for maintaining animal populations. However, the lack of breeding space resulting from an increased number of strains and the decline in fertility caused by inbreeding inhibits the reproduction of subsequent generations. Reproductive technologies, such as gamete preservation and artificial fertilisation, have been developed to overcome these problems. These approaches efficiently produce offspring of laboratory, domestic and wild animals, and can also be used to treat human infertility. Gamete preservation using sperm contributes to improvements in reproduct

Abstract:

Animal domestication is a natural selection experiment the important result of which is a great increase in the rate of appearance of new forms and in the wild range of variation of organisms. Analysing different aspects of this problem, D.K. Belyaev has came to a hypothesis that the morphological and physiological reorganisation of domestic animals has been going by the way of unconscious selection of animals on their behaviour, carried out by person at the very first stages of domestication (Belyaev, 1979). To testify this hypothesis, a population of tame silver foxes has been produced in lo

Abstract:

Oxidative stress occurs when the levels of reactive oxygen species (ROS) overcome the antioxidant defenses of the organism, jeopardizing several biological functions, including reproduction. In the male reproductive system, oxidative stress not only impairs sperm fertility but also compromises offspring health and survival, inducing oxidative damage to lipids, proteins and nucleic acids. Although a clear link between oxidative stress and male fertility disorders has been demonstrated in humans and laboratory rodents, little information is available about the implications of impaired redox home

Abstract:

Reproductive process leads to dynamic changes in metabolism and energy consumption, which may be responsible for the excessive production of free radicals (oxidants) that are generated during the physiological process of oxygen consumption. As the ovary is a metabolically active organ, it produces oxidants. Growing follicles, granulose cells of Graffian follicles and ovulated follicles all produce both enzymatic and non-enzymatic antioxidants to preserve themselves from the oxidative damage of oxidants. Oxidants and antioxidants are involved in several reproductive functions such as the regula

Abstract:

The control of reproductive processes involves the integration of a number of factors from the internal and external environment, with the final output signal of these processes being the pulsatile secretion of gonadotrophin-releasing hormone (GnRH) from the hypothalamus. These factors include the feedback actions of sex steroids, feed intake and nutritional status, season/photoperiod, pheromones, age and stress. Understanding these factors and how they influence GnRH secretion and hence reproduction is important for the management of farm animals. There is evidence that the RF-amide neuropept

Abstract:

In the article, the authors present data on the development parameters of replacement heifers, milk productivity, reproduction rates, and economic longevity of Simmental cows of domestic and foreign selection in the farms of the mountainous regions of the Altai Republic and the Altai Territory. For the first time, the authors determined the efficiency of breed use (EIP) according to the method of M.A. Svyazhenina (2012) and proposed to supplement this method with an indicator of the age of insemination of heifers. In all the herds studied, the authors note the optimal indicators of herd reprod

Abstract:

Time budget studies focus on the amount of time individual animals allocate to mutually exclusive activities. In the wild, horses’ behavioural patterns revolve around maintenance behaviour and reproduction (Forgacz 1999). They have evolved as nomadic, trickle feeding, prey animals. Hence, they don't necessarily suit the confines of a domestic environment where their “mutually exclusive activities” may include stereotypical behaviour.Various time budgeting studies have shown that “the behaviour of horses within the domestic management system was significantly different to that of the wild horse

Abstract:

MicroRNAs (miRNAs) are small non-coding interfering RNA molecules capable of post-transcriptionally regulating gene expression through sequence-specific base pairing to messenger ribonucleic acid (mRNA). In recent years, hundreds of miRNAs have been identified in humans, various animals and plants. The action of miRNAs has been examined in several biological processes, including tissue morphogenesis, development, cell proliferation and differentiation, apoptosis, immunity, metabolism, and major signaling pathways. Changes in miRNA expression have also been analyzed in the context of various pa

Abstract:

Preservation of aboriginal breeds and populations of domestic animals is one of the main tasks set before the world community by the Convention on Biological Diversity. With the intensification of Ukrainian livestock breeding with the use of commercial imported breeds, there is a threat of loss of domestic unique gene pools that carry original sets of alleles responsible for high adaptability and resistance to environmental factors in combination with high productivity and reproduction. The article assesses the current state of the Askania gray Ukrainian breed population and the dynamics of it

Abstract:

Techniques to manipulate reproduction and productivity are well established features of the husbandry of domestic animals and the treatment of human infertility. Similar approaches are feasible in marsupials, but little work has been done to apply our considerable basic knowledge of marsupial reproduction to produce practical artificial breeding. If the reproduction and productivity of marsupials could be more effectively controlled it would greatly aid research and profoundly change both current practice in the management of zoo animals, and the strategies employed for the breeding and conser

Abstract:

Leptin, an adipocyte-derived cytokine (adipokine) has plethora of physiological roles in the body, particularly in the onset of puberty, viz. reproduction and immune function of an animal. Moreover, body fatness which is a crucial determinant of meat quality is governed by blood leptin level. Since its discovery in 1994, various research groups have explored its potential role in animal production, reproductive fitness and immune function which ultimately determine the profitability of livestock rearing. Leptin binds with leptin receptor (LEPR) and activates different intracellular signaling p

Abstract:

Indigenous domestic animals such as cattle, sheep, goats, pigs, and chickens have a natural resistance to endo- and ecto-parasites and are tolerant in terms of harsh environmental conditions. These species orginated from the Fertile Cresent between 12,000 and 10,000 BP before migrating into surrounding continents. In view of limited information on the reproductive status of indigenous breeds, it is important to examine their semen characteristics in order to select males to improve livestock production. We have largely relied on existing literature but also our published and ongoing research o

The most important side in breeding work is reproduction and its indicators. In modern conditions, domestic cattle breeds are losing their popularity, there is an intensive expansion of native breeds by Holstein bulls of American lines, which on the one hand leads to an increase in milk productivity, but at the same time leads to a decrease in the productive longevity of the livestock used. On the territory of the North-Western Federal District of the Russian Federation, mainly black-and-white root breeds are used, both locally selected, such as the Kholmogorskaya breed of cattle, the Yaroslav
