“…For example, cows undergo a significant shift in their hormonal status and metabolic profile during the period of pregnancy. In particular, with increasing periods of pregnancy, the content of estrogens and progesterone in the blood of cows significantly increases, the concentration of total lipids, cholesterol, and glucose increases (Edelhoff et al, 2020;Kaurivi et al, 2020;Pascottini et al, 2020).…”

The article describes the results of the research on the formation of the bone system of the carcasses of purebred and crossbreed steers. Three groups of animals were selected for the experiment by the analog method. The first group consisted of purebred steers of Simmental breed, the second and third groups consisted of ½ blooded steers of Simmental and Charolais beef breeds, respectively. The dynamics of age changes in the skeleton were studied by determining the absolute relative weight and calculating the growth coefficient. The research showed that the absolute weight of the skeleton has increased with the development of the test steers. Thus, if the skeleton mass of newborn steers was 7.44, 7.34, and 8.30 kilos for each group, then at the age of 6 and 12 months, it had increased to 29.

The results of meat productivity of young cattle of beef breeds (Auliekol, Kazakh Whitehead, Galloway, Hereford) depending on the breed, sex, and age (young bulls, steers-calves, heifers, first-calf cows, adult cattle-cows, bulls, calves) grown in the Western Region of the Republic of Kazakhstan during winter, turning winter (pre-spring), early spring and spring periods are given. The animals were divided into three groups according to their breed and growing conditions. The highest slaughter yield among adult animals was found in the cow of the Auliekol breed-63,7% with a pre-slaughter weight of 532.8 kg; the lowest yield was in the cow of the Hereford breed -53,6% with a pre-slaughter weight of 410.0 kg. Studies of young animals showed that the highest and the lowest values were 61.3% in a bull of the Auliekol breed with a pre-slaughter weight of 460.1 kg and 50.8% in a bull of the Hereford breed with a pre-slaughter weight of 372.3 kg, respectively. The proportion of muscle, fat, connective, and bone tissue in the slaughter process is determined. The muscle tissue of the animals of higher fatness in the I and II groups consists of 56.6-57.3% of carcass weight, fat-15.7-16.1%, and connective, bone and cartilage-26.9-27.2%. The muscle tissue of the animals of I and II groups of average fatness amounts to 59.7-60.2% of carcass weight, fat-9.8-10.3%, connective, bone and cartilage-29.8-30.1%, the muscle tissue of the animals of III group of average fatness amounts to 58.4% of carcass weight, fat-10.2%, connective, bone, and cartilage-31.4%. The amino acid content of cattle cuts of different breeds is almost identical in proline-0.68-0.7%, serine -0.76-0.79%, alanine -1.09-1.13%, tyrosine -0.63-0.66%; but there are also significant differences, such as argininefrom 0.65 to 1.27%, lysine-from 0.86 to 1.66% and leucine-from 0.87 to 1.56%. The highest total amino acid content is 13.59% and the lowest is 9.26%. As a result, the food and biological quality of beef depending on breed, age, living conditions, pre-slaughter housing, slaughtering, and production processes.

Fundamental Concepts, Knowledge Gaps and Key Concerns Relating to Welfare and Survival of Stranded Cetaceans

et al. 2022

Wildlife management can influence animal welfare and survival, although both are often not explicitly integrated into decision making. This study explores fundamental concepts and key concerns relating to the welfare and survival of stranded cetaceans. Using the Delphi method, the opinions of an international, interdisciplinary expert panel were gathered, regarding the characterisation of stranded cetacean welfare and survival likelihood, knowledge gaps and key concerns. Experts suggest that stranded cetacean welfare should be characterised based on interrelated aspects of animals’ biological function, behaviour, and mental state and the impacts of human interventions. The characterisation of survival likelihood should reflect aspects of stranded animals’ biological functioning and behaviour as well as a 6-month post-re-floating survival marker. Post-release monitoring was the major knowledge gap for survival. Welfare knowledge gaps related to diagnosing internal injuries, interpreting behavioural and physiological parameters, and euthanasia decision making. Twelve concerns were highlighted for both welfare and survival likelihood, including difficulty breathing and organ compression, skin damage and physical traumas, separation from conspecifics, and suffering and stress due to stranding and human intervention. These findings indicate inextricable links between perceptions of welfare state and the likely survival of stranded cetaceans and demonstrate a need to integrate welfare science alongside conservation biology to achieve effective, ethical management at strandings.
