“…For poor diets, despite the old results of Devendra (1978), the debate is still running regarding differences in digestive efficiency between goats and other ruminants, but the digestibility seems to be similar with good diets (Sales et al, 2012).…”

“…This is consistent with the fact that, for similar mixed diets, the rumen pH of goat is higher by about 0.4 point compared to cattle (Sauvant et al ., 2018c). For poor diets, despite the old results of Devendra (1978), the debate is still running regarding differences in digestive efficiency between goats and other ruminants, but the digestibility seems to be similar with good diets (Sales et al ., 2012).…”

The aim of this Research Reflection is to describe the basic rumen function of goats and its modification in response to environmental factors, as well as to discuss similarities and differences when compared to other ruminants. In so doing we shall reveal the adaptive capacity of goats to harsh environments. The basic rumen function in goats is similar to other species of ruminants, as stressed by the opportunity to apply the updates of feeding systems for ruminants to goats. The rumen epithelium acts as a protective barrier between the rumen and the host, but it can be damaged by toxic compounds or acidosis. The rumen also plays an important role in water balance, both for dehydration and rehydration. Recent studies show that the microbiota exhibits a high fractional stability due to functional redundancy and resilience, but this needs more investigation. The microbial community structure differs between goats and cows, which explains the difference in sensitivity to milk fat depression following intake of high lipid diets. Goats also differ from other ruminants by their enhanced ability to feed-sort, but as with cows they can suffer from acidosis. Nevertheless, goats can be considered to be very resistant to environmental factors such as water stress, salt stress or heat stress, and this is especially so in some endogenous breeds. They also are able to detoxify tannins, polyphenols and other secondary metabolites. Some new trials involving feeding behaviour, microbiota and omics or approaches by meta-analyses or modelling will improve our knowledge of rumen function in goats.

“…Известно, что генотипические особенности отражаются на активности функционирования регуляторных систем, что сопровождается изменениями в интенсивности и направленности пищеварительных и обменных процессов. Вследствие различий в адаптивных возможностях пищеварительного аппарата у животных разных генотипов в желудочно-кишечном тракте создаются специфические условия, влияющие на активность микроорганизмов и биосинтез метаболитов [19][20][21][22][23].…”

Relevance. It is known that genotypic features affect the activity of the functioning of regulatory systems, which is accompanied by changes in the intensity and direction of digestive and metabolic processes. The digestibility and use of nutrients, as well as the need for them in animals of different origins are not the same. Therefore, the study of the species composition and enzymatic properties of microorganisms in hybrid animals is of great interest. Scientific research in this area can expand the species diversity of cellulolytic microorganisms through the use of wild forms of sheep, in which the process of splitting and digesting raw fiber occurs more intensively.Methods. The species composition of the microflora and the main groups of microorganisms (total microbial number (OMH), lactic acid, enterococci, yeast-like fungi and cellulolytic microorganisms) were determined in the microbiology laboratory of the L.K. Ernst FITZ VIZH in 2021–2023 by seeding tenfold dilutions into accumulative and differential diagnostic media, followed by counting their number (CFU/ml) by groups of microorganisms.Results. According to the results of the study of the species composition of the scar content of hybrid sheep of different bloodlines, the largest number of microorganisms in the main groups was observed in hybrids — sheep 1/4 Argali × 3/4 Romanovskaya. The largest number of cellulolytic microorganisms with high enzymatic activity was isolated from four-breed hybrids: 1/32 Argali × 7/32 Romanovskaya × 8/32 Mouflon × 16/32 Katadin.

“…Biological substantiation of complete feeding of animals requires consistent studies of the processes of nutrition, digestion and metabolism [11][12][13][14]. Only a uniform tension in the work of a multi-chamber stomach of ruminants at the optimum for this type of combination in the diet of coarse, juicy and concentrated feed can greatly enhance the digestive capacity of the stomach and intestines.…”
