In order to fi ll the existing protein defi ciency in the rations of farm animals in particular dairy cows it is necessary to input feed lupins as widely as possible in crop rotations. Lupin is a very versatile forage crop it can be used in feed as herbage, in the form of haylage, silage, in compound feed as a protein additive, as well as a green manure crop to increase soil fertility. Questions of protein nutrition should be to be quickly resolved, both in the production of protein and in its standardized rational use. Unbalanced protein rations increase feed consumption per unit of production, thereby increasing its prime cost. In the world soya is generally recognized as a protein feed, but in the Kaliningrad region as in most of regions in our country, it does not maturate being a heat-loving crop. Under these environments the inclusion of extruded lupine grain in the composition of energy-protein concentrates for the production of compound feed has become an alternative to replacing expensive soya. The researches have been carried out it the cattle farm of LLC “Temp” in the Guryevsky area in the Kaliningrad region (March-May 2019) on feeding lactating cows energy-protein concentrate from extruded grain of narrow-leaved lupine, fl ax, triticale, subjected to heat treatment on a press extruder. For this purpose two groups of lactating cows of Black-and-White breed (control and experimental) have been formed using the method of pairs of analogs per 11 heads in each. Cows of the control group have received the main ration of the farm, and cows of the experimental group in addition to the main ration have received compound feed with extruded energy-protein concentrate based on lupine. As a result of research, the positive infl uence of energy-protein concentrate based on lupine in compound feed on the dairy productivity of cows has been established. Recipes of concentrate and compound feed with concentrate for lactating cows, the volume of inclusion of components in the concentrate and in the compound feed have been calculated. During the experiment, the milk yield in the experimental group of cows has increased by 62,4 kg or 8,0 %, than in the control group. From the cows of the experimental group the conditional profi t has been received in the amount of 1684,8 rubles per head.

Ct Data

ECTemp™ is a heart rate (HR)-based core temperature (CT) estimation algorithm mainly used as a real-time thermal-work strain indicator in military populations. ECTemp™ may also be valuable for resting CT estimation, which is critical for circadian rhythm research. This investigation developed and incorporated a sigmoid equation into ECTemp™ to better estimate resting CT. HR and CT data were collected over two calorimeter test trials from 16 volunteers (age, 23 ± 3 yrs; height, 1.72 ± 0.07 m; body mass, 68.5 ± 8.1 kg) during periods of sleep and inactivity. Half of the test trials were combined with ECTemp™’s original development dataset to train the new sigmoid model while the other was used for model validation. Models were compared by their estimation accuracy and precision. While both models produced accurate CT estimates, the sigmoid model had a smaller bias (−0.04 ± 0.26°C vs. −0.19 ± 0.29°C) and root mean square error (RMSE; 0.26°C vs. 0.35°C). ECTemp™ is a validated HR-based resting CT estimation algorithm. The new sigmoid equation corrects lower CT estimates while producing nearly identical estimates to the original quadratic equation at higher CT. The demonstrated accuracy of ECTemp™ encourages future research to explore the algorithm’s potential as a non-invasive means of tracking CT circadian rhythms.

Massey University assumed management responsibility for "Riverside", a 723 ha sheep and beef cattle farm 8 km north of Masterton in Master-ton in March 1978. The farm is leased to the University under the terms of the will of the late Mr Sydney Campbell to assist in the accumulation, expansion and dissemination of knowledge about agriculture, with particular emphasis on agriculture in the Wairarapa. A lo-year farm development programme instigated in 1978 resulted in the sale of the beef herd and the winter stocking rate of sheep being increased to 15.1 suiha by 1984 (9.7 sulha in 1978). In 1985 stocking rates were sharply reduced following a severe drought and the current mixed 2-year bull beef and breeding ewe policy was introduced. Recent research has focused on drought-tolerant pasture species. In late 1992 sheep and beef cattle farmers (n=lOO) were surveyed to identify local information needs and how Riverside could continue to serve the region's research and extension requirements. Information related to fertilisers and farm management were most frequently rated as the most imporant current needs. Keywords: extension, research, Riverside, teaching, Wairarapa

Using of silage and haylage of forage legumes in ruminant nutrition and promotion of promoting proper forage conservation techniques should be an important strategy in livestock production in our country. Forage legumes are difficult to ensile, so it is necessary to apply the starter culture of selected strains of lactic acid bacteria that support the ensiling process and prevent bacterial butyric fermentation and thus contribute to the preservation and improvement of silage and haylage quality. In this paper, the influence of bacterial inoculant ?Silko for alfalfa? on the quality of silage and haylage of alfalfa in two separate trials is presented. The inoculant is a combination of homofermentative lactic bacteria Lactobacillus plantarum and Pediococcus spp. The first-cut alfalfa in the second year was used for silage and haylage. The silage was examined in mini-silos in the laboratory, and the haylage at the cattle farm where the plant material was cuts were collected in experimental silo bags. The treatments were control (untreated silage, i.e. haylage) and silage, i.e. haylage treated with inoculant ?Silko for alfalfa? (rate of 5 ml t-1 fresh material). The silages were analyzed after 90 days, and haylage after 40. The inoculant ?Silko for alfalfa? has been found to maintain the nutritive value of silage and haylage and to improve their chemical, energy and fermentation parameters relative to the control. Since ?Silko for alfalfa? positively affects the correct lactic acid fermentation of silage and haylage and contributes to a lesser loss of nutritional value and energy it is expected that it can promote a high level of productivity of ruminants, and thus contribute to the growth of profit in livestock production.
