Purpose: to study the effect of feeding lactating cows with a feed additive enriched with a biocomplex of free L-amino acids of plant origin on the indicators of functional homeostasis, productivity and quality characteristics of milk.Materials and methods. Research and production tests were carried out on the basis of the OS "Streletskaya" branch of the Federal State Budgetary Scientific Institution "Federal Research Center of Legumes and Groats". To conduct scientific and production tests, 2 groups of cows of 3-4 lactation were formed, 70 heads each. The groups were formed on the principle of analogous pairs.The cows of the experimental group, starting from the second day after calving, in the morning, once a day, received a granulated feed additive "ZEO-AMINO" (Russia) fraction 0.2-0.7 mm at the rate of 2% of the dry matter of the ration daily for the first 100 days lactation. Experimental animals were monitored daily. Clinical examination of animals was carried out with obligatory control of the general condition, thermometry, counting of respiratory movements and rumen contractions, assessment of the udder condition. The productivity of cows was determined according to the results of control milking. Morphological and biochemical blood tests were performed.Results. It was revealed that the daily use of a granular feed additive of fraction 0.2-0.7 mm, starting from the second day after calving, once a day at the rate of 2% of the dry matter of the diet during the first 100 days of lactation, contributes to an increase in the average daily milk yield of cows on average by 15.9%; by 7 months lactation, an increase in the average daily milk yield was established by an average of 18.3%. It was found that feeding the supplement to cows after calving due to better absorption of nitrogen in the diet and accumulation of proteins in the animal's body allows partially neutralizing the negative consequences of negative energy balance after calving, and contributes to a more intensive recovery of live weight loss, which is reliably confirmed by indicators of animal productivity. The results of a biochemical blood test suggest that the use of a feed supplement in obtaining milk has a positive effect on the assimilation of the diet, metabolism and assimilation processes in the body, activates a number of vital functions during the normal course of physiological processes and ensuring functional homeostasis, which ultimately determines increasing the milk production of animals. Analysis of the quality indicators of milk allows us to conclude that the mass fraction of fat when feeding the additive increased by an average of 0.12 abs. %; the mass fraction of protein increased by an average of 0.22 abs.%.Conclusion. To increase milk productivity, reduce the negative effects of negative energy balance after calving, and more intensively restore body weight loss, as well as increase the efficiency of using feed proteins and normalize metabolic processes, it is recommended that daily use of the feed granulated dietary supplement "ZEO-AMINO" fraction in the diets of dairy cows 0.2-0.7 mm at the rate of 2% of the dry matter of the diet, starting from the second day after calving, once a day during the first 100 days of lactation.

Abstract A study was carried out to estimate the balance of metabolizable protein (MP), metabolizable energy (ME), calcium, and phosphorus in 12 recently calved (RC) and early lactation (EL, 42 - 50 days after calving) Gyr x Holstein dairy cows grazing in a Leucaena leucocephala and Cynodon plectostachyus intensive silvopastoral system (ISS) and receiving energy and protein supplementation. Dry matter (DM) availability from the grazing paddocks, nutrients offered and their balance were estimated. On average, the available forage DM per animal.day-1 was 44.7 kg for C. plectostachyus and 11.8 kg for L. leucocephala. EL cows had greater requirements of MP, ME, and minerals than RC cows. In RC cows, ME, MP, and mineral requirements were supplied by the total diet, while EL cows exhibited a negative energy balance. For both RC and EL cows, ME was the limiting dietary factor, whereas MP and P were found to be in excess. If cows were only to receive ISS forages with no supplementation, estimated daily milk yield would be 10 and 12 litters for RC and EL cows, respectively. Under tropical conditions, based on ISS forage intake, RC and EL cows can meet most of their ME, MP, calcium, and phosphorous requirements.

In order to effectively provide the body of cows with energy during the increasing the milk yield without the risk of acidosis, progressive animal breeders of the Altai Territory include wet flattened corn grain in the composition of concentrated feed. The question of the expediency and economic effectiveness of using wet flattened corn grain for cows of various physiological groups – first-calf heifers and mature animals continues to be debatable. Therefore, a comparative assessment of two options for feeding wet flattened corn grain to cows under the conditions of the Altai Territory is considered promising in modern animal husbandry and is of great practical interest. The purpose of the work was to identify the optimal and economically feasible option for using wet flattened corn grain in the rations of lactating cows. When using wet flattened corn grains in an amount of 7,1 % of the nutritional value of the ration the first-calf heifers during the period of increasing the milk yield, productivity has increased by 20,9 %. The average daily milk yield was 17,3 kg, which significantly exceeded the indicator of the control group (P > 0,95). The inclusion of wet flattened corn grains in the ration of mature cows in the amount of 1 kg for 30–35 days before calving, then 4,5 kg from 15 to 75 days after calving allows us to get the average daily milk yield of 30 kg or 20,3 % higher than that of the control group of herdmates (P > 0,95). The effectiveness of the use of wet flattened corn grain had significant indicators: the total profit from the sale of dairy products of the first-calf heifers of the experimental group amounted to 16 251,3 rubles/head, and from the sale of milk of mature cows of the experimental group it was 30 346,43 rubles/head.

The replacement of lost body tissue in modern dairy cows usually takes place later in the same lactation, once milk output begins to decline. Individual cows may not regain all lost body energy in the first lactation leading to a greater deficit to be replenished in the second. This results in carry-over effects from one lactation to the next, on both yield and non-yield traits. The use of random regressions and Fourier series allows modelling of cyclical changes in a trait over seasons (Meyer, 2000) and could be used to model multiple lactation energy balance changes in dairy cows. Parameters of these cyclical functions might then be analysed for relationships with traits of economic importance such as health, fertility and survival. The objectives of this study were 1) to model phenotypic daily milk yield, fresh feed intake, liveweight and condition score using random regression techniques, 2) to combine daily estimates obtained in objective 1) into an overall energy balance for each day of the first three successive lactations, 3) to compare energy balance curves over three lactations and 4) to investigate the feasibility of modelling energy balance in the first three lactations using harmonic analysis.

Metabolic Adaptations

This review examines the metabolic adaptations that occur in response to negative energy balance and their potential putative or functional impact on appetite and food intake. Sustained negative energy balance will result in weight loss, with body composition changes similar for different dietary interventions if total energy and protein intake are equated. During periods of underfeeding, compensatory metabolic and behavioural responses occur that attenuate the prescribed energy deficit. While losses of metabolically active tissue during energy deficit result in reduced energy expenditure, an additional down-regulation in expenditure has been noted that cannot be explained by changes in body tissue (e.g. adaptive thermogenesis). Sustained negative energy balance is also associated with an increase in orexigenic drive and changes in appetite-related peptides during weight loss that may act as cues for increased hunger and food intake. It has also been suggested that losses of fat-free mass (FFM) could also act as an orexigenic signal during weight loss, but more data are needed to support these findings and the signalling pathways linking FFM and energy intake remain unclear. Taken together, these metabolic and behavioural responses to weight loss point to a highly complex and dynamic energy balance system in which perturbations to individual components can cause co-ordinated and inter-related compensatory responses elsewhere. The strength of these compensatory responses is individually subtle, and early identification of this variability may help identify individuals that respond well or poorly to an intervention.
