Scientists of the Bashkir Research Institute of Agriculture of the Ufa Federal Research Center of the Russian Academy of Sciences are conducting scientific research on the development of biotechnological methods for housing and feeding calves of the preweaning rearing period using probiotic drugs. The purpose of the research was to conduct scientific and economic tests of the universal microbiological starter culture of probiotic action Biolax-U for the prevention and treatment of dysbiosis in heifers and to determine its effect on the live weight gain of young animals. Experimental investigations have been conducted in two farms in the Republic of Bashkortostan, where two groups of heifers (control and experimental) of Black-and-White breed of the preweaning rearing period have been formed, selected according to the method of pairs of analogues, taking into account origin, age, live weight. The expediency of using the universal microbiological starter culture of probiotic action Biolax-U as a medicinal product in the diets of calves has been investigated. Feeding of the universal microbiological starter culture of probiotic action Biolax-U allowed us to increase the average daily gains in the live weight of young animals, to improve the functioning of the gastrointestinal tract. It has been found according to the results of control weighings of heifers that the live weight of heifers of the experimental groups was higher by the end of the experiment than the control herdmates in both experiments, and in the first experiment the difference was statistically significant at P < 0,01. It has been found that the absolute gain in the live weight of animals of the experimental groups receiving Biolax-U exceeded the control herdmates in the first experiment by 8,3 kg or 10,0 %, in the second experiment by 7,6 kg or 9,9 % as the result of improving the digestive system, increasing the digestibility and availability of feed in the diet. The heifers of the experimental groups in both experiments had an advantage in terms of average daily gain. For example, in the first experiment this advantage was 93 g/day or 10,0 %, in the second experiment it was 84,4 g/day or 9,9 %.

This study aimed to assess forage production, animal performance, and the chemical composition of Tanzania grass pasture fertilized with 50, 100, 200, and 400 kg ha-1 of nitrogen. The variables analyzed were: leaf mass, daily accumulation rate, leaf/stem ratio, average daily gain, stocking rate, live weight gain per unit of area crude protein, neutral detergent fiber, and in vitro dry matter digestibility of leaves. The pasture management maintained the pasture height at 50 cm by using a continuous grazing method with the adjustment of stocking rate. The experimental design was a randomized block with three replicates. The leaf mass increased linearly in response to nitrogen, with an increase of 1003 kg (34%) observed between a nitrogen content of 50 and 400 kg ha-1. Nitrogen did not affect the average daily gain, but increased the stocking rate and live weight gain ha-1. The value of crude protein and neutral detergent fiber were higher with increased nitrogen levels, whereas the leaf digestibility did not affect nitrogen use. The comparison of 50 and 400 kg ha-1 levels indicated that there was an average increase of 19.2% in the leaf crude protein. The increased application of nitrogen fertilizer in Tanzania grass improved the chemical composition and animal performance; with regard to studied variables, the dose of 200 kg ha-1 resulted in the greatest improvement.

The purpose of research and production experiment in the conditions of Akhmetov farm located in the Vysokogorsky district of the Republic of Tatarstan was to study a new sanitary litter material and the effect on the indoor environment, production, viability and feed input required to rear gosling broilers. The experiment found that the new sanitary litter material, made of thermochemically and biotechnologically processed woodworking waste, over the entire period of research was characterized by higher qualities compared to raw sawdust. Accordingly, in the end, the moisture of the said material was lower by 28.5 %, the total microbial count and numbers of microscopic fungi were less by 13.3 % and 19.9 %, respectively. The said litter material helped to improve the environment in the poultry house, which reduced harmful gases (carbon dioxide – 0.11 % and ammonia – 0.33 mg/m3), dust – 0.9 mg/m3 and microorganisms – 8.9 thousand bwt/m3. Ultimately, this contributed to a higher daily live weight gain by 7.51 % and livestock viability by 1.80 %, and, sequentially reduced feed input per 1 kg of live weight gain by 4.98 %, as compared with the control.

ABSTRACT1. A primary growth of perennial ryegrass was cut on 8 to 11 May (early) or on 12 June (late) for comparison with the primary growth of a tetraploid red clover, which was cut either on 1 or 2 June (early) or on 28 June (late). The crops were ensiled, after wilting for about 4h, with the addition of formic acid at 2·21/t fresh crop. The silages were given ad libitum alone or with rolled barley at 11·5 g dry matter per kg live weight to 40 British Friesian steers initially 3 months old and 108 kg live weight.2. On average there was no significant difference in digestibility between perennial ryegrass and red clover. However, the rate of decline in digestibility with time was greater with perennial ryegrass than with red clover.3. Calves given silage of red clover as the sole feed ate more dry matter and grew faster than calves given grass silage (P <0·001) but supplementation with barley reduced the intake of red clover silage to a greater extent than that of perennial ryegrass silage. Barley supplementation increased live-weight gain of calves given perennial ryegrass from 0·32 to 0·83 kg/day and that of calves given red clover from 0·63 to 0·99 kg/day (interaction P <0·05). The results did not indicate a higher net efficiency of utilization of the legume. Date of cut had no significant effect on dry-matter intake but earlier cutting resulted in an increase in live-weight gain from a mean of 0·61 to 0·77 kg/day (P <0·001).4. The results show that high rates of live-weight gain (0·74 kg/day) can be achieved by calves given silage of red clover and that earlier cutting of herbage for silage does not always result in higher intakes of dry matter. Supplementation of silages with barley can reduce markedly the difference in intake and live-weight gain apparent when the silages are given as sole feeds.

The Difference

1. In the summer of 1958, 15 mg. of hexoestrol was administered to Blackface wether lambs in one of the following ways; 5 mg. before weaning followed by two 5 mg. tablets at weaning, three 5 mg. tablets at weaning, and thirdly a single 15 mg. tablet at weaning. In a further series of experiments in 1959 the effect of both raising the pre-weaning implantation to 10 mg., and the total hexoestrol dosage to 20 mg. was studied.2. Suckled lambs implanted with 5 mg. of hexoestrol at the milk clip gained significantly more in live-weight (18%) up to weaning in 1958 than did untreated lambs; in 1959 the difference was only 11%.3. Between weaning and the end of the trial all treatments with the exception of that in which hexoestrol dosage was raised to 20 mg. showed a very highly significant increase in live-weight gain over untreated lambs, the increases ranging from 26 % to 54%.4. In neither year was the overall gain in live-weight from pre-weaning to the end of the trial significantly increased by implanting part of the hexoestrol dose prior to weaning.5. Live-weight gain of the lambs was not significantly increased when three 5 mg. tablets of hexoestrol replaced a single 15 mg. tablet.6. The implanting of lambs with 20 mg. hexoestrol failed to give a response superior to that obtained with 15 mg. hexoestrol.7. Each group of lambs receiving hexoestrol treatment showed an increased average carcass weight.

Winter Feeding

1. Three winter feeding experiments (1954–57) were carried out using small flocks of Border Leicester x Cheviot ewes tupped by a Suffolk ram.2. The feeds used were various combinations of (a) silage, (b) hay, (c) ‘winter grass’, and (d)concentrates. Their value in late pregnancy was compared in terms of performance of the ewe and the birth weight of the lambs.3. In addition, in one year (1956–57) the effect of level of nutrition in early pregnancy and during the first 28 days of lactation was studied.4. It was found that ‘winter grass’ could replace silage and hay where a concentrate ration was being fed.5. Satisfactory results were obtained with a concentrate ration of ⅜ lb. per head per day rising to ¾ lb. per head per day by lambing time.6. In the mild winter of 1956–57 a group of ewes produced normal healthy lambs when fed entirely on ‘winter grass’ during the latter half of pregnancy.7. The intensity of grazing of the ewes in early pregnancy affected their live-weight gain, but this seemed to have little effect on lamb production.8. A high plane of nutrition during early lactation resulted in a significantly greater live-weight gain of lambs over this period. The difference had been reduced to a non-significant level by mid-June.9. None of the treatments imposed had any very marked effect on the nematode egg-output of the ewes.

The authors studied productivity and product quality under industrial poultry production technology. The productivity of broiler chickens of Ross-308 and Hubbard Iza-F-15 was different during floor rearing. Broiler chickens of Ross-308 outperformed Iza-F-15 chickens in body weight and average daily gain. The live weight at the slaughter of Ross-308 chickens was 2,360 g. The live weight of the chickens of Iza-F-15 was 2088 g. The conversion of feed to produce was higher in the chickens of Ross-308 cross by 0,06 kg compared with the chickens of Iza-F-15 and amounted to 1.64 kg per 1 kg of live weight gain. The survival rate was high for Ross-308 chickens (95.8%). The safety of the flock of the Izu-F-15 chickens was 2.2 per cent lower and was 93.6 per cent. Slaughter yield in the chickens cross Ross-308 is higher than in the group of chickens cross Iza-F-15. Meat quality is also better in Ross-308 chickens. Growing broiler chickens of Ross-308 cross for meat under industrial technology allowed to get more profit compared to the use of poultry of Iza-F-15 cross. At the exact cost of feed, 1 kg of live weight gain was 7.1 roubles, and per 1 head of chick was 19.1 roubles. The profitability level is also 12.6% higher for the broiler chickens of Ross-308 cross. The cumulative indicator the European productivity index is higher for chickens of Ross-308 breed, compared with chickens of Iza-F-15 breed on 56 units. This index was 341 and 285, respectively.

The growth of lambs on natural and cultiavated pastures was studied in 1979—1980 in northern Lapland at 69°40’ N and 27° 05’ E. The natural pasture was a peninsula covered by various wild grasses, bearing willow and birth and with sedge and horsetail by the shore. On the cultivated pasture timothy predominated. The experiments started in mid June, when the age of the lambs averaged three months, and lasted to mid September. During that time, the animals received no supplemental feeds. The grazing density on the natural pasture was 1.5—3.2 lambs/ha and on the cultivated pasture 15—20 lambs/ha. The lambs on the natural pasture grew significantly slower (P < 0.05) than those on the cultivated pasture. The difference in live-weight gain was especially marked in June and from the beginning of August. In lambs moved from the natural pasture to the cultivated pasture in mid August the growth rate was somewhat better than in lambs kept on the natural pasture throughout, but growth diminished in all the lambs in September. The slaughter criteria were also better for the lambs on the cultivated pasture than for the others.

The leading farms of the Sumy region studied the peculiarities of the growth of repair heifers of Ukrainian Black-and-White (PZ PE "Burynske") and Red-and-White (LLC "Mlynivskyi complex") dairy breeds. The absolute and relative indicators of live weight gain of heifers in the age dynamics from birth to 18 months of age were studied. Heifers of the Ukrainian Red-and-White dairy breed (36.2 kg) were the best in terms of live weight at birth in comparison with the peers of the Ukrainian Black-and-White dairy breed (33.9 kg). Their advantage persisted during the 18-month growing period. Repair heifers of the Ukrainian Red-and-White dairy breed at the final stage of development with an average live weight of 414.2 kg exceeded the peer of the Ukrainian Black-and-White dairy breed with a highly reliable difference of 15.5 kg (P <0.001). The development of repair heifers of both breeds within the obtained live weight indicators ensured their increase at the time of mating age at the level of 76-80% of the minimum target standards set for the first-born cows of dairy type of the created breeds. The average daily gains in live weight in the milk period averaged 810.4 g in heifers of the Ukrainian Black-and-White dairy breed, and 847.3 g in their peers of the Ukrainian Red-and-White dairy breed, the highest in the animals of the Ukrainian Red-and-White dairy breed herd LLC "Mlynivsky complex". The results of research showed that with the creation of appropriate conditions for feeding and keeping repair heifers of Ukrainian Black-and-White and Red-and-White dairy breeds were capable of high growth intensity.

Metabolizable Energy Intake

ABSTRACTAn experiment was carried out with 20 male veal calves to study differences in energy metabolism between pure Dutch Friesian and Holstein Friesian crossbred calves, containing a high proportion of Holstein Friesian genes (0·79). Two metabolizable energy (ME) intakes were given. The effects of genotype and ME intake on live-weight gain and its fat and protein composition were measured by indirect calorimetry and by the total collection of faeces and urine. Energy and nitrogen balances were measured for each calf during the last 5 weeks of the fattening period of 22 weeks.The difference in live-weight gain between the Holstein Friesian crossbreds and the Dutch Friesian calves was not significant but small differences in protein and fat composition of live-weight gain were found. Fat gain was closely related to ME intake (r = 0·95), but the correlation coefficient between ME intake and protein gain was only 0-36. Live-weight gain had a high correlation with protein gain (r = 0·70) but a lower correlation with fat gain (r = 0·29).Veal calves at the end of the fattening period had a declining protein gain as age increased. Calves given a high ME intake (> 2 × maintenance) may require diets containing less than 216 g crude protein per kg diet at the end of the fattening period.The study indicates that Holstein Friesian crossbred veal calves and Dutch Friesian veal calves have similar ME requirements.

Complex researches on studying of efficiency of use of a premix in which the filler was mustard protein-containing feed concentrate “Gorlinka” as a part of compound feeds for replacement pullets and laying hens have been carried out. Its influence on digestibility and digestibility of nutrients of diets, hatchable qualities of eggs, morphological and biochemical parameters of blood of experimental poultry, economic efficiency of production have been studied. It has been found that the input of the feed to young poultry of the experimental group of the studied premix contributed to a more complete digestion and use of nutrients. According to the results of weighing experimental pullets to 150-day age in the control group the live weight was 1719,23 g, and the average daily gain was 7,83 g, in the experimental group the live weight of the pullets was 1775,25 g, and the average daily gain was 8,74 g, which exceeded the indicator of the control group, respectively, by 3,26 % (P > 0,99) and 11,62 % (P > 0,95). Feed expenditures per 1 kg of live weight gain of poultry in the experimental group were lower than in the control group by 3,73 %, this allowed to obtain additional net income by saving the cost of feed per 1 kg of live weight gain of poultry 1,86 rubles. The economic effect in the experimental group of replacement pullets during the experiment reached 627,75 rubles. When calculating feed expenditures per 1 kg of egg mass, the following results have been obtained: in the control group this figure was 2,18 kg, which was higher than in the experimental group by 0,12 kg. Thus, the input of the experimental premix into feed for laying hens of the parent herd contributed to the increase in egg production and egg weight, as well as a reduction in feed expenditures by 10 eggs. It has been established that the experimental group was superior in all indicators of quality assessment of daily chicks of the control group, which received the premix based on sunflower oil cake as part of the feed. It has been received the chicks in the experimental group 257 heads, and that 14 heads more than in the control group. The chicks of the experimental group surpassed the chicks of the control group in the live weight of one chicken by 0,52 g, and substandard chickens in this group were less by 0,67 %. At an average realizable value of 1000 eggs was 9000 Rub, gross income in experimental group was higher than in control by 0,81 %, which resulted in additional net income from sale of eggs 2916 Rub. Economic eff ect through the use of the premix made up 3782,2 Rub.
