“…Some evidence suggests that the superior heat tolerance ability of Jerseys is based on their less reduction in milk yield compared to Holsteins ( Bryant et al, 2007 ; Smith et al, 2013 ). Similar studies ( Mylostyvyi et al, 2021 ) have reported greater heat tolerance ability of Brown Swiss compared to Holsteins. Otto et al (2019) explored the genetic basis of heat tolerance using crossbred cows ( Bos indicus vs. Bos taurus cattle).…”

Heat tolerance is the ability of an animal to maintain production and reproduction levels under hot and humid conditions and is now a trait of economic relevance in dairy systems worldwide because of an escalating warming climate. The Australian dairy population is one of the excellent study models for enhancing our understanding of the biology of heat tolerance because they are predominantly kept outdoors on pastures where they experience direct effects of weather elements (e.g., solar radiation). In this article, we focus on evidence from recent studies in Australia that leveraged large a dataset [∼40,000 animals with phenotypes and 15 million whole-genome sequence variants] to elucidate the genetic basis of thermal stress as a critical part of the strategy to breed cattle adapted to warmer environments. Genotype-by-environment interaction (i.e., G × E) due to temperature and humidity variation is increasing, meaning animals are becoming less adapted (i.e., more sensitive) to changing environments. There are opportunities to reverse this trend and accelerate adaptation to warming climate by 1) selecting robust or heat-resilient animals and 2) including resilience indicators in breeding goals. Candidate causal variants related to the nervous system and metabolic functions are relevant for heat tolerance and, therefore, key for improving this trait. This could include adding these variants in the custom SNP panels used for routine genomic evaluations or as the basis to design specific agonist or antagonist compounds for lowering core body temperature under heat stress conditions. Indeed, it was encouraging to see that adding prioritized functionally relevant variants into the 50k SNP panel (i.e., the industry panel used for genomic evaluation in Australia) increased the prediction accuracy of heat tolerance by up to 10% units. This gain in accuracy is critical because genetic improvement has a linear relationship with prediction accuracy. Overall, while this article used data mainly from Australia, this could benefit other countries that aim to develop breeding values for heat tolerance, considering that the warming climate is becoming a topical issue worldwide.

The article deals with the results of research on the economic efficiency of the use of mixed ligand complexes of Zinc, Manganese and Cobalt in the feeding rations of highlyproductive cows of Ukrainian Red-Spotted Dairy breed in the first 100 days of lactation. The research was performed on five groups (one control and four experimental) of analogous cows in the conditions of ALC “Terezyne” Bila Tserkva district of Kyiv region. The control was the optimal dose of mixed ligand complexes of Zinc, Manganese and Cobalt, which was previously established with a concentration of 1 kg of dry matter (DM) of the feed mixture (FM), mg: Zinc – 60.8; Manganese – 60.8 and Cobalt – 0.78. For the 2nd experimental group, the concentration of these trace elements was increased by 10 %, and in the 3rd, 4th and 5th experimental groups – on the contrary, the concentration of Zinc, Manganese and Cobalt in 1 kg of DM of feed mixture was reduced by 10 %, 20 and 30 %, respectively, compared with the control. The best results on milk yield of natural and basic fat content were got from cows of the 4th experimental group, where the concentration of Zinc, Manganese and Cobalt due to their mixed ligand complexes in 1 kg of DM of feed mixture was, mg: Zinc – 48.6; Manganese – 48.6; Cobalt – 0.62. The cost of products got from experimental cows ranged from UAH 12702.3 up to UAH 13783.7 and it was the highest in the 4th experimental group. It was set up that for cows of Ukrainian Red-Spotted Dairy breed in the first 100 days of lactation the most economically advantageous was the dose of mixed ligand complexes, in which the concentration of Zinc and Manganese was 48.6 mg, and Cobalt – 0.62 mg/kg DM, which allowed to obtain a profit of 14.37 % more than in the control group. Doses of mixed ligand complexes with a concentration of Zinc and Manganese – 66.9 mg; 54.7 and 42.6 mg, and Cobalt – 0.86 mg; 0.7 and 0.55 mg/kg CF gave a much lower economic effect. Additional profit in the 2nd experimental group amounted to UAH 66.8 or 1.34 %; in the 3rd – UAH 95.6 or 1.92 % and in the 5th – UAH 561.6 or 11.28 %, compared with the control group.

“…Feeding of farm animals must be carried out according to detailed standards, taking into account the chemical composition and nutritional value of the feed used. This makes it possible to more fully balance the diets, thereby increasing the productivity of animals at the exact feed costs (Slavetsky, 2002;Razumovsky et al, 2002;Yakovchik & Ganushchenko, 2011;Johansson et al, 2012;Amamou et al, 2019;Borshch et al, 2021;Denkovich et al, 2021;Mylostyvyi et al, 2021).…”

Studies on the effectiveness of the inclusion of sodium humate in the diet of young cattle were conducted on four groups of animals. Installed improvement in the consumption of hay by the bulls of the experimental groups by 12.5–20 % compared with the control young was found, as a result of which they consumed more feed units by 1.5, 2.3, and 3.5 %, exchange energy – by 2.4, 3.9 and 5.1 %, digestible protein – by 1.2, 2.1 and 3.7 %. As a result of the inclusion of sodium humate in the diet as part of the KR-2 compound feed, the amount of hemoglobin in the blood of animals of the II experimental group increased by 5.8 %, in III – by 6.8, in IV – by 7.8 % compared to control analogs. With the growth of calves in the blood, the bactericidal activity of blood serum increased by 1.3, 1.9, and 2.5 %, lysozyme activity increased by 0.1 %, 0.2, 0.3 %, which indicates an increase in natural resistance in animals whose diets were injected with the studied peat and sapropel preparation. The use of sodium humate in the feed of bulls in the composition of compound feed KR-2 has a positive effect on the feed consumption, physiological condition, resistance of animals, which provides an increase in the average daily increase in live weight by 3.2–9.4 % while reducing the cost of its production by 2.9–8.5 percent.
