“…Cows previously identified as phenotypically slow eaters of concentrate have a lower motivation to seek forage, a higher tendency to rest close to water or in sheltered areas than fast eaters [ 86 ]. However, cows of high and low feed efficiency do not differ in the daily distance travelled in steppe rangelands [ 44 ], and no relationship between liveweight gain and home range size or proportion of time spent on summer farm meadows was found in cows grazing on boreal forests [ 87 ]. Cows differing in their phenotypical habit to use hilly terrains graze different parts of the same pasture; “hill climbers” use rougher terrain and begin travelling to water about one hour later than cows previously classified as “bottom dwellers” [ 88 ], showing the degree of asynchrony in the motivation to eat or drink of different individuals [ 37 ].…”

Understanding the behaviour of grazing animals at pasture is crucial in order to develop management strategies that will increase the potential productivity of grazing systems and simultaneously decrease the negative impact on the environment. The objective of this review was to summarize and analyse the scientific literature that has addressed the site use preference of grazing cattle using global positioning systems (GPS) collars in the past 21 years (2000–2020) to aid the development of more sustainable grazing livestock systems. The 84 studies identified were undertaken in several regions of the world, in diverse production systems, under different climate conditions and with varied methodologies and animal types. This work presents the information in categories according to the main findings reviewed, covering management, external and animal factors driving animal movement patterns. The results showed that some variables, such as stocking rate, water and shade location, weather conditions and pasture (terrain and vegetation) characteristics, have a significant impact on the behaviour of grazing cattle. Other types of bio-loggers can be deployed in grazing ruminants to gain insights into their metabolism and its relationship with the landscape they utilise. Changing management practices based on these findings could improve the use of grasslands towards more sustainable and productive livestock systems.

“…Where livestock grazing might be permitted and productive, such tools should be investigated collaboratively with farmers and other relevant authorities and stakeholders, and adjusted according to site knowledge, scientific monitoring, and management objectives, to determine density-and/or durationbased management plans. We note that seasonal grazing with winter stall feeding indoors may be preferred for practical reasons, but moderate year-round "natural grazing" outdoors (Vermeulen, 2015) is often preferable as densities are naturally regulated by winter food availability, reducing risk of overgrazing typical of seasonal regimes (Goderie et al, 2013;Tofastrud et al, 2020). In relation to diet selection and density effects, we can expect cattle at moderate densities to have limited effect on woody vegetation (Calleja et al, 2019), and short duration, high density "boom and bust" grazing may reduce woody vegetation but compromise livestock health and production (Teruel-Coll et al, 2019).…”

Cattle Grazing Effects on Vegetation and Wild Ungulates in the Forest Ecosystem of a National Park in Northeastern China

There is evidence that cattle grazing in forests limits big cat abundance. There is concern, too, about competition with wild ungulate prey through bottom-up effects on vegetation. Hence, there have been calls to remove or control forest livestock grazing in aid of restoring endangered large carnivores and their prey. To help inform scientific debate and decision making, we explored cattle-vegetation-prey dynamics in Northeast Tiger and Leopard National Park, northeast China and present a reappraisal of livestock grazing in the context of coexistence and an integrated approach to land use in China. Inside long-term forest grazing enclosures, wild boar (Sus scrofa) density increased with cattle density. Roe deer (Capreolus pygargus) density and occurrence probability of wild boar and roe deer were not influenced by cattle density. Wild ungulate densities were not related with the number of annual shoots, i.e., forage plant abundance. The presence/absence and abundance of annual shoots was not related with cattle density. Wild ungulate density had mixed associations with vegetation structure; arbor tree diameter at breast height (DBH) and habitat “openness” increased with cattle density. Finally, inside and outside enclosures had different vegetation characteristics and wild boar densities, while roe deer densities were equal. We conclude that cattle density and associated changes to vegetation have positive, negative, and neutral effects on two wild ungulate prey species. Each of these factors warrant consideration in evidence-based management decisions in regard to regulating ungulate community composition to support different large predators as preferred prey in core areas and corridors of habitats.

“…In this regard, in beef cattle breeding there is a tendency towards a transition from the extreme compact (solid) type with a short and square body on low legs to a type that is larger in live weight and well-defined meat forms [9,10].…”

Body types of Aberdeen Angus bulls and their relationship with meat production

The study results of Aberdeen-Angus breed bull meat production, depending on the body type, are presented. The first group consisted of bulls descended from stud bulls of large tall type, the second group consisted of bulls descended from stud bulls of the small compact type. It was determined that at the age of 18 months, bulls from large-type parents reached a weight of 442 kg, and from small-type parents - 413 kg. The first group bulls had a higher pre-slaughter weight by 31.4 kg and heavy carcasses compared to the second group bulls by 28.3 kg or 13.5% (P > 0.99). The first group bulls, being higher-legged, produced carcasses with a higher bone content (by 4.08 kg) during slaughter compared to the second group. In their carcasses, there was 4.52 kg of boneless meat per 1 kg of bones, while in the second group carcasses - 5.03 kg. However, in general, when boning semi-carcasses of the first group, more boneless meat was obtained, by 9.9 kg. or by 11.72% (P > 0.99) compared with the second group.
