The use of grain feed mixtures in the diets of young cattle at an early age does not fully meet their need for minerals, because of which other nutrients cannot be used eff ectively enough. In this regard the current situation determines the need to use and develop recipes for grain feed mixtures with the inclusion of relatively inexpensive natural mineral additives in their composition from the early age of calves. The purpose of the work was to experimentally substantiate the inclusion in the grain feed mixture of different doses of smectite kizelgur and their effect on the productivity of young cattle during the preweaning period with its summer and winter housing. The doses of inclusion of smectite kizelgur in the composition of grain feed mixture for calves of the preweaning period and their effect on productivity and energy consumption per unit of growth have been studied. The most effective doses of smectite kizelgur in the composition of grain feed mixture for calves during the preweaning growing period under the conditions of their summer and winter maintenance have been established. In the experiment the content of vital chemical elements from different parts of the calves’ body in the hair has been studied as an indicator of the mineral status of their body when feeding smectite kizelgur in the grain feed mixture. It has been found during the research that when rearing calves in the preweaning period the use of different doses of smectite kizelgur in the diet has the positive effect on their growth and development, interior indicators and increases the economy of the industry. The inclusion of 20 g/head/day in the grain mixture in the summer period, and 30 g/head/day in the winter period of smectite kizelgur is the most economically justified.

Mice of two strains (a laboratory strain of white mouse and a fancy strain of coloured mouse) were fed on a proprietary cubed diet and were given to drink tap water, or water containing 26 mg per litre of one of the following antibiotics: chortetracycline hydrochloride, ampicillin, or tylosin tartrate. In the first experiment growing mice were given these diets for 8 weeks from 4 weeks of age. Ampicillin produced weight increases in both strains (significant in the white mice), chlortetracycline produced an increase in the coloured mice and a reduction in the white mice, while tylosin reduced weight increases in both strains. The results of fortnightly weighings of the control mice and those receiving ampicillin showed that in the coloured mice the effect was marked at an early age, while in the white mice it tended to spread over the growing period. In a second experiment with breeding mice, using does of both strains, ampicillin increased litter size in both strains (significantly in the case of the coloured mice), chlortetracycline increased litter size in the white mice only, and tylosin did so in the coloured mice only. All three antibiotics increased litter birth weights in coloured mice (ampicillin significantly), but reduced them in white mice. Weight increases from birth to weaning of selected groups of 8 mice showed that antibiotics had little effect in the white mice, and that ampicillin and tylosin improved the rate of gain in the coloured mice (ampicillin significantly).

The article presents the results of cross-breeding of mountain cattle with Russian polled breed. The growth and development of the crossbreed and purebred bull-calves of these breeds in the mountainous province of Dagestan have been studied in a comparative aspect. Efficiency of highland pastures use by crossbreed animals in comparison with pure-bred mountain peers has been established. The young cattle was grown according to the technology of meat cattle breeding “cow — calf”. In ablactation, the crossbred bull-calves had a living weight of 191.3 kg versus 159.3 kg in peers of mountain cattle. This figure was higher by 32.0 kg or 20.1% compared to purebred bull-calves of mountain cattle. At 12 months of age, the crossbred animals were also superior in living weight in comparison of young mountain cattle by 40.1 kg or 18.4%. According to this indicator, the advantage in crossbred animals at 15 months of age remained. The live mass of crossbred bull-calves at 18 months of age equaled to 399.5 kg against 332.6 kg of purebred mountain peers, the difference in favor of the former was 66.9 kg or 20.1%. Average daily growth of crossbreed bull-calves during the growing period was 122 grams or 20.8% higher. Young crossbred cattle had a clear advantage in terms of physique. Heavy carcasses with high slaughter yield were obtained from it. The conducted studies indicate the effectiveness of cross-breeding of mountain cattle with Russian polled breed in the mountainous province of Dagestan.

Изучено влияние введения разных доз тканевого биостимулятора на биохимические показатели сыворотки крови ремонтного молодняка крупного рогатого скота. Опыт проводился в Алтайском крае на 4 группах ремонтных телочек Приобского типа черно-пестрой породы по 10 голов в каждой. При подборе животных учитывались возраст (1 мес) и живая масса (51,3±1,48 кг). Продолжительность опыта составляла 14 дней. Животным контрольной группы подкожно однократно вводили физиологический раствор в дозе 3,0 мл на 1 голову, I опытной — тканевый биостимулятор в дозе 2,0 мл, II — 3,0 мл, III — 4,0 мл на 1 голову. Опытную партию тканевого биостимулятора изготовили из субпродуктов и боенских отходов пантовых оленей по запатентованной технологии. Материалом для приготовления препарата служили мезентеральные лимфоузлы и средостения, селезенка, печень, матки с плодами (2—3 мес), плацента, отобранные в асептических условиях во время убоя здоровых животных. Введение тканевого биостимулятора телочкам в разных дозах способствовало повышению некоторых исследуемых биохимических показателей сыворотки крови. Наиболее оптимальной дозой применения тканевого биостимулятора следует считать 3,0 мл/гол, что способствует повышению содержания общего белка в сыворотке крови на 1,4% (P≤0,05), глюкозы — на 22,6% (P≤0,05) и снижению содержания холестерина на 12,3% (P≤0,05). The effect of the administration of different doses of the tissue biostimulant on the biochemical blood serum indices of replacement young cattle was studied. The experiment was carried out in the Altai Region in 4 groups of 10 Black-Pied replacement heifers of the Priobskiy type. When selecting the animals, their age (1 month) and live weight (51.3±1.48 kg) was taken into account. The experiment lasted 14 days. Saline solution was injected under the skin to the animals of the control group at a dose of 3.0 mL per 1 head; the tissue bio-stimulant was administered in the following doses: in the 1st trial group — 2.0 mL per head; the 2nd trial group 3.0 mL per head; the 3rd trial group — 4.0 mL per 1 head. The trial batch of the tissue bio-stimulant was made from velvet antler deer by-products and slaughterhouse offal by using the patent-protected technology. The tissue biostimulant was made from mesenteric lymph nodes and mediastinums, spleen, liver, uteri with 2—3 month old fetuses, and placentae collected under aseptic conditions from healthy animals at slaughter. The administration of the tissue bio-stimulant to heifers in different doses increased some of the studied biochemical blood serum indices. The tissue biostimulant dose of 3.0 mL per head should be considered the most optimal one; it increased the total protein content in blood serum by 1.4% (P≤0.05), glucose — by 22.6% (P≤0.05), and decreased cholesterol content by 12.3% (P≤0.05).

SUMMARYA longitudinal study in England and Wales of two dairy, five beef-fattener and three beef-suckler herds was carried out to identify risk factors for young cattle excreting verocytotoxin-producingEscherichia coliO157 (VTEC O157). A total of 1383 cattle, selected into cohorts at 0–24 months were sampled between March 2000 and February 2001. Mixed-effects logistic regression was employed to identify significant associations between VTEC O157 isolation from rectal faecal samples and explanatory factors (P< 0·001 unless shown). The results revealed a positive association with feeding root crops and a negative association with animals fed silage, milk (P= 0·001) or grain (P= 0·027). Cattle in suckler herds (P= 0·001) and those changing group between sampling visits were identified as negatively associated with VTEC O157 presence. The recovery of VTEC O157 varied throughout the year. However, the winter period from December to February was a risk factor in the multivariable analysis. Cattle in pens were 4·7 times more likely to shed VTEC O157 than those group-housed or at pasture. VTEC O157 detected in pooled environmental faecal pats and biofilm of the water supply within a group's enclosure were positively associated with an animal's VTEC O157 status in the multivariable logistic regression, as was detection of VTEC O157 in the pooled faecal pats at the previous visit.
