Abstract Sow milk is usually enough to meet the need for nutrients of three weeks age piglets. However from the beginning of life they need supplemental nutrients in the form of creep feeding. The objective of this study was to survey the usefulness of special mixed feeds (super starter, pre-starter, starter feeds) given as creep feeding and feeding to suckling pigs, as well as the use of immunostimulant for their health, better growth and development. The study showed that suckling pig fed with special super starter, pre-starter and starter mixed feed depending on age, as well as young animals additionally treated with intramuscular injected immunostimulant better by growth rate. The highest indicators for the live weight of piglets at the age of 60 days (weaning) and for the milk content of sows were in the experimental group, which was intramuscularly injected with an immunostimulator The highest live weight of (weaning) piglets aged 60 days was in treated groups.

Изучены рост и развитие бычков — помесей красной степной с казахской белоголовой породой в равнинной провинции Дагестана. Установлено, что помесный молодняк, по сравнению с чистопородным скотом красной степной породы, имеет более высокую живую массу при рождении на 1,8 кг, или 7,3%. При отъеме в 8-месячном возрасте помеси имели живую массу 210 кг против 187,6 кг у красного степного молодняка, что на 22,4 кг, или 11,9% выше. В 12-, 15- и 18-месячном возрасте живая масса помесных бычков равнялась 291,8 кг, 359,7 и 436,6 кг, соответственно, или на 28 кг, 36 и 45,8 кг больше по сравнению с красным степным скотом. Среднесуточные приросты помесных бычков за период выращивания и откорма составили 760 г, что выше на 12,1% по сравнению с чистопородным красным степным молодняком. После заключительного откорма и убоя помесные бычки дали тяжеловесные туши с хорошим поливом. По массе парной туши они превосходили чистопородных аналогов на 31,3 кг, или 15,6% с преимуществом выхода туши на 2,4%. Убойный выход у бычков опытной группы составил 58,7%, контрольной — 55,8%. От помесных бычков были получены тяжеловесные шкуры массой 27,1 кг, от чистопородных — 21,6 кг, преимущество по этому показателю имели помесные животные 5,5 кг, или 25,4%. Для увеличения производства говядины в равнинной провинции Дагестана рекомендуем скрещивание коров красной степной породы с быками казахской белоголовой породы. The growth and development of bulls of red steppe crossbreeds with the Kazakh white-headed breed in the flat province of Dagestan were studied. It was found that young crossbreed animals in comparison with purebred red steppe cattle have a higher live weight at birth by 1,8 kg or 7,3%. When weaning at 8 months of age, cross-bred bulls had a live weight of 210 kg against 187,6 kg in red steppe young, which is 22,4 kg, or 11,9% higher. At 12, 15 and 18 months of age, the live weight of crossbred bulls was 291,8 kg, 359,7 and 436,6 kg, respectively, or 28 kg, 36 and 45,8 kg more than the red steppe cattle. The average daily growth of cross-bred bulls during the growing and fattening period was 760 g compared to 678 g, that is, they were 12,1% higher compared to purebred red steppe young. After the final fattening and slaughter, the cross-bred bulls gave heavy carcasses with good watering. By weight of the paired carcass, they were superior to purebred counterparts by 31,3 kg or 15,6% with an advantage of 2,4% carcass yield. The slaughter yield of bulls in the experimental group was 58,7%, 55,8% in the control group, respectively, with an advantage in favor of crossbreeds of 2,9%. Heavy skins weighing 27,1 kg were obtained from crossbreed bulls, 21,6 kg from purebred ones, and crossbreed animals of 5,5 kg or 25,4% had an advantage in this indicator. Studies have shown that in order to increase beef production in the lowland province of Dagestan, it is necessary to use crossbreeding of the breeding stock of the red steppe breed with bulls of the Kazakh white-headed breed.

The growth rate and bone metabolism indicators were monitored in broiler chickens receiving the feed supplemented with clinoptilolite. One-day-old broiler chickens ROSS 308 were divided into control (C) and experimental (E) groups with 100 males and 100 females per group. The chickens received the complete feed mixture BR1 from 1 to 10 days of age, followed by the feed mixture BR2 until the age of 30 days, and the feed mixture BR3 until the end of the experiment (40 days). The feed mixtures of the experimental group were supplemented with clinoptilolite (commercial additive ZeoFeed) at a level of 0.5% (BR1), 1.5% (BR2) and 2.5% (BR3), replacing the corresponding portion of wheat. Feed mixtures and drinking water were provided ad libitum. The live weight of broiler chickens in both the control and experimental group increased steadily during the experiment. At the end of the experiment, live weights of experimental females (2,416 g) and males (2,829 g) were higher than those of control females (2,345 g) and males (2,694 g) by 3% and 5%, respectively. Significant differences in the live weight between groups were found from the age of 30 days (P ⪬ 0.05 and P ⪬ 0.01). At the age of 40 days, the chickens were slaughtered and the femur and tibiotarsus of the right leg were analysed for the content of dry matter, ash, calcium, phosphorus and magnesium. The ash content in dry matter ranged from 53.0 to 54.1% in group C and from 51.7 to 53.2% in group E. The Ca and P contents in dry matter in group E were lower than those in group C, except for Ca and P in the male tibiotarsus. In both groups, regardless of sex, the ash content was higher in the tibiotarsus than in the femur. Since fat levels in bones of the experimental group were increased (females by 19.5% in the femur and 21.3% in the tibiotarsus; males by 22.0% in the femur and 26.3% in the tibiotarsus), which could affect the values obtained, ash, calcium, phosphorus and magnesium were determined in the fat-free dry matter. The trends found in the originally determined dry matter were maintained, i.e. lower levels of ash, Ca, and P in the experimental group, except for male Ca in both kinds of bones. The corresponding levels in the fat-free dry matter were relatively higher as compared to the original dry matter. The results of the study showed that up to 2.5% of clinoptilolite in the diet had no adverse effect on performance and bone metabolism indicators of growing broiler chickens. Thus, it can be used as a suitable feed additive to broiler diets due to its positive effect on nutrient utilization, mechanism of digestion and pollutant elimination in connection with food safety issues.

The use of clinoptilolite is an effective means of increasing the gain and live weight of calves. The application does not cause difficulties in the methods of introducing the additive to calves. Natural clinoptilolites of various deposits are presented in a wide range on the feed additives market. Aims: The objective of the work was to study the effectiveness of natural mineral clinoptilolite on physiological and zootechnical indicators of growth and development of calves. Methodology: The study was carried out on 39 clinically healthy Holsteinized black-and-white calves selected at random, 13 animals per group. For 85 days, the calves of the experimental group received a basic diet enriched with natural mineral clinoptilolite to increase the efficiency of growth and development at a dosage of 25-50 and 50-100 g / head / day. Blood samples were taken from the jugular vein at the end of the supplement feeding (n = 5) for physiological, biochemical and immunological studies. Results: In the course of the study, it was found that in the experimental groups there were higher gains in live weight by 7.3 and 4.7% in comparison the control, and low feed costs per 1 kg of gain. Feeding clinoptilolite promoted an increase in the concentration of Ca in the blood of calves of the dairy period by 14.2% (p <0.05), an increase in phagocytic activity by 4.87 (p <0.05), the phagocytic number was higher by 0.20 (p < 0.05) units. Conclusion: The totality of the information presented confirms the physiological adequacy for calves to the introduction of natural mineral clinoptilolite in the indicated dosages.

It is known that one of the most important reasons for the birth of weak calves is the impact of adverse factors on the physiological status of the cow, which in turn affects the intrauterine and postnatal development of the fetus and newborn. The results of studying the introduction of different doses of tissue biostimulator to cows during the dry period and its effect on the development of the conformation of calves received from them have been presented in the article. The experiment was carried out in 2019 on cows of Priobsky type of Black-and-White breed and calves obtained from them. In order to conduct the experiment four groups of dry cows-analogs have been formed with 10 heads in each for 55–60 days before the expected calving at the age of III lactation and older. When selecting animals the live weight and milk productivity of cows for the previous lactation have been taken into account. The highest growth rate has been observed in calves from cows the 2nd experimental group, which exceeded the control by 24,4 % (P ≤ 0,001). The best indicators of conformation development have been also observed in calves obtained from cows of the 2nd experimental group, which were injected subcutaneously with 22,5 ml of tissue preparation. So, oblique body length have been greater by 12,6 % (P ≤ 0,001), chest girth by 17,3 % (P ≤ 0,001), width of hook bones by 21,0 % (P ≤ 0,01), the width of the pin bones by 15,0 % (P ≤ 0,05). The lengthiness index was by 11,5 % higher (P ≤ 0,001), the blockiness index was by 4,1 % higher (P ≤ 0,05), and the boniness index was by 10,6 % lower (P ≤ 0,05) than in the control group herdmates.

The aim of this work was to investigate the growth performance of Diaphanosoma birgei fed with two Chlorophyceae algae, Ankistrodesmus gracilis and Haematococcus pluvialis using monoalgal diets and simpler mixed diets. D. birgei was daily fed on four treatments: 1) 100% Ankistrodesmus gracilis (Ag); 2) 100% Haematoccocus pluvialis (Hp); 3) 25% A. gracilis + 75% H. pluvialis (Ag-25+Hp-75) and 4) 75% A. gracilis + 25% H. pluvialis (Ag-75+Hp-25). The fecundity curve of D. birgei showed that the mixed feed Ag-25+Hp-75 and temperature 24±2°C triggered fast fecundity at approximately two days. The fecundity was low when based only on H. pluvialis (Hp), albeit with greater longevity (19 days) and a higher number of broods (8). D. birgei fed on Ag and Ag-75+Hp-25 diets in this experiment sustained higher growth rate and higher lipid content in these treatments. The present study showed that A. gracilis diet and mixed microalgae diets tested were able to support the egg production and development of D. birgei.

The Relationship

The objective of the study was to determine the effect of growth and development intensity in Holstein replacement heifers on economically important animal traits. The intensity of growth was assessed by the average live weight gain until 14 months of age. In addition, live weight and height at the sacrum at 14 months of age were analysed as indicators of growth and development when evaluating the length of productive life. The milk yield of first-calvers increased as the average daily live weight gain in the rearing period increased. An opposite tendency was recorded for cows in their second and third lactation and the total production also decreased with a higher growth rate of heifers. The analysis of the relationship between growth rate and the following reproduction traits revealed that the increased average daily live weight gain to 14 months was subsequently associated with reduced reproduction efficiency in cows. The differences between the groups with the lowest and the highest average live weight gains in the number of days open in the first and second calving interval were 26.78 and 17.47 days, respectively. This tendency was also confirmed in the other reproduction traits analysed. Productive life was significantly longer in animals with the lowest intensity of growth and development compared to the other groups (2.17 to 5.49 months, <i>P</i> < 0.01).

And Performance

ABSTRACTTo investigate possible pre-test environmental effects on testing station performance, pigs from a total of 107 litters from two breed types were weaned on one of three treatments: weaning at 3, 5 or 8 weeks of age, with a different creep-feeding regime on each. At 8 to 10 weeks of age, litter groups (usually consisting of two boars, one male castrate and one gilt) were sent to a Meat and Livestock Commission testing station and performance-tested from 27 to 85 kg live weight on twice daily to-appetite feeding.Weaning treatment significantly affected live weight at 50 days and boar growth rate and feed efficiency on test, but carcass traits were largely unaffected. Boars weaned on the 8-week treatment showed a significant advantage in index score of two-thirds of a standard deviation over those weaned at 3 weeks. A smaller number on the 5-week treatment were intermediate but did not differ significantly from those on the other two. It is concluded that wide variation in the weaning methods of herds sending pigs to a testing station could affect selection decisions. Ways of removing any bias by standardizing weaning methods or by statistical adjustment are discussed.

AbstractThe objective of this study was to assess the growth and development of carcass composition of entire male and female lambs of three British hill breeds (Scottish Blackface, Welsh Mountain, and Shetland), from weaning to approaching maturity, when kept under conditions designed to be nutritionally non-limiting. Lambs were weaned at 8 weeks of age and given a high-quality pelleted diet ad libitum until slaughter at one offive different degrees of maturity. The Gompertz growth function was used to characterize, for each genotype, the growth curve and to provide estimates of mature weight. As expected, there were significant effects of breed and sex on both food intake and growth rate. Growth rate was depressed, relative to the Gompertz fit, during the months of October to January, and intake was similarly depressed. The estimates of mature weight for the females of each breed were: Scottish Blackface, 69; Welsh Mountain, 61; Shetland, 46 kg. The mature weights of the males were found to be not significantly different from 1-3 times the mature weight offemales. Relationships between carcass composition and live weight were derived by allometric regression. This study provides the first full description of the growth and meat production potential of the three breeds.

Reproductive Indices

According to the experiment, the productive effect of different amounts of grain of the triticale of Harroz variety in feed for the reproductive indices of feeding rabbits was established. According to the tasks assigned, five groups of nursing rabbits were selected and formed according to the principle of analogues. To feed the experimental nursing rabbits, a full granulated mixed feed was used in the structure of which there was a different content of triticale grain: II research group – 10.0%, III, IV and V research groups - 20.0%, 30.0% and 40.0% respectively . Nursing rabbits of the 1st control group were fed full-fat mixed fodders, which were balanced for the main nutrients, but did not contain triticale grain. In the study of the multiplicity of feeding rabbits with different contents of crushed grain of the triticale of the Harroz variety, it was higher in the 3rd and 4th experimental groups (in the ration of 20 and 30% of the crushed grain of triticale) with an index of 8.0–8.2 heads (P < 0.05). The large-fruited index predominated in the nursing rabbits of the 4th experimental group and amounted to 65 g; in the 1st, 2nd, 3rd and 5th groups it was 62, 63, 64, and 61g. The amount of milk of nursing rabbits is an indicator that positively correlates with fecundity, the weight of rabbits at birth (large-fruited), the preservation of the nest. Milk index was also the best in nursing rabbits of the 4th group and amounted to 2.83 kg, which is 0.09–0.24 kg more than in all other groups (P < 0.01). By the number of rabbits with weaning at 35 days, the fourth group of nursing rabbits predominated, this index was 7.1 g. The average live weight of one head during separation was higher by 40–50 g in the 3rd and 4th test groups compared to the first control group and amounted to 0.75 and 0.76 kg (P < 0.05). According to preliminary indications, the best nest weight in weaning during 35 days was the nursing rabbits of the 4th group – 5.36 kg, which is 0.47 kg higher than the control (P < 0.05). The highest percentage of conservation of rabbits before weaning at 35-day-old age was observed in groups 3, 4 and 5, and was at the level of 94.59; 93.42; 97.1%. It was found that the structure of the ration of nursing rabbits with a content of crushed grain of triticale of Harroz 20, 30 and 40% was significantly influenced the preservation of the nest. The index – the index of the reproductive qualities of feeding rabbits (IVKK), based on the indicators of large-fruited, milk and number of rabbits with weaning (35 days) was higher in feeding rabbits of 3rd and 4th groups and amounted to 126.4 and 128.8. The maximum reproductive indices of feeding rabbits provided a structural content in the diet of 30% of the crushed grain of the triticale of the Harroz variety (the fourth research group). The ration (30% of the triticale crushed grain) ensured the growth of the multiplicity by 8.5%, the size of the fetus by 5%, the milkness of the rabbits by 9%, the weight of the nest at weaning at 35 days old by 9.6%, and the complex index of IVKK by 6.5%.
