Intensive System

The experiment was conducted with forty four pre-pubertal stages female lambs of 12.5±2.5 kg average live weight and 7.5±0.5 months of average age. Animals were equally and randomly allocated into two feeding groups, intensive and semi-intensive feeding systems with 22 animals in each group. Under intensive system, animals were fed concentrate mixture (15.0% crude protein (CP); 11 MJ metabolizable energy (ME)/kg dry matter (DM)) at the rate of 1.5% of live weight with ad libitum green grass from May to November and supplied urea molasses straw (UMS) in place of green grass from December to April. There were no significant differences (p > 0.05) in service per conception, litter size, lambing interval, gestation length, service period, birth weight and weaning weight between intensive and semi-intensive feeding system. Reproductive traits and productive traits were not affected by feeding system. Conception rate was higher (98.0%) in semi-intensive system than intensive system (83.0%). On the other hand lamb survivability was higher in intensive system than in semi-intensive system. The semi-intensive feeding system is found to be better to rear sheep for commercial purpose compared to intensive feeding system.

One of the main tasks of the development of the national economics of the Altai Republic is a rapid and signifi cant rise in animal husbandry, both in terms of increasing the number of all animal species, and in terms of increasing the productivity of maral breeding. New methods, new breeds, and highly productive types and lines are needed to solve these complex problems. Any breed is characterized by the unique gene pool and is the result of a long, purposeful and hard work. The scientists had the task of breeding and researching a breed type of maral of Altai-Sayan breed, which is common in some regions of the Republic. The object of the research was marals of the breed type has been bred in the APC BF “Tenginsky”, which were distributed both in the Republic of Altai and in other regions of the Russian Federation. In the sharply continental environments of the highlands animals have been bred that are characterized by a large live weight, high antler productivity and reproductive traits. With regard to the typicality and technological properties of antlers, marals in the APC BF “Tenginsky” occupy the first place in the production of antler products and breeding young animals. A complex evaluation of the method for the distinctiveness, uniformity and stability of breed type of marals has shown that the antler productivity of Tenginsky type antlers has higher indicators not only relative to the marals of neighboring farms, but also higher than the average indicators of the AltaiSayan breed by 30 %. Adult Siberian stags of Tenginsky type have live weight in the range 270–350 kg. Marals of the tengin type belong to large deer with a height of 150–165 cm at the withers. The horns of marals of the Tenginsky type are large in size and have 6–7 appendages. A distinctive feature of the main array of antlers in the Tenginsky type of antlers is the presence of short, but thick in girth trunks. The antler productivity of individual Siberian stags reaches 19,0–23,6 kg of raw antlers. The bred type includes high-class animals (91,6 % elite and class I), which annually produce more than 5,5 t of antlers and at least 350 breeding calves.

ABSTRACTFive hundred and seven British Friesian × Ayrshire bull calves were reared on a once-daily milk replacer feeding system from approximately 6 to 72 days of age in four naturally ventilated, unheated calf houses differing in design and degree of insulation. Environment within the calf houses was monitored each hour. Differences in design and degree of insulation produced small but significant differences in internal house temperature, humidity and air movement which had no measurable effect on calf daily live-weight gains.Calves receiving 0·6 kg/day compared with 0·3 or 0·4 kg/day of milk replacer plus concentrates ad libitum ate less concentrates but had higher daily live-weight gains (0·56 compared with 0·49 kg/day respectively) (P < 0·001). Rations supplying similar amounts of metabolizable energy from varying proportions of milk:concentrate resulted in comparable live-weight gains. Results suggest that calf viability was affected by level of nutrition and that low levels of milk replacer feeding resulted in higher mortality. Naturally ventilated, unheated calf houses were demonstrated to be suitable for rearing calves in south-west Scotland.

The examination was made on the effect of systematic factors (parturition group, calving season, birth type, calf gender, and birth type-calf gender interaction) and age at first conception on the expression of reproductive traits (gestation length, service period, fertility intensity and calf birth weight) in 143 Simmental cows. The overall mean (?) for gestation length, service period, intercalving period and calf birth weight was 284.14 days, 153.82 days, 416.92 days and 35.40 kg, respectively. The parturition group effect on all fertility traits was highly significant (P<0.01). The calving season statistically significantly (P<0.05) affected the intercalving period and calf birth weight. Birth type induced very significantly longer gestation (P<0.01) and higher calf birth weight in singles (P<0.01) and significantly longer service period in twins (P<0.05). Calf gender had a very significant effect (P<0.01) only on calf birth weight, and the interaction between birth type and calf gender significantly affected gestation duration only (P<0.05). The regression effect of age at first conception on all fertility traits was not significant (P>0.05).

Background: The Black Bengal goat (BBG) is well adapted food animals with profitable productive and reproductive traits being naturally reared to enhance economic status and food security in rural people. Bangladesh government has taken program through establishment of ‘Government Goat Development Farms’ (GGDF) to enhance the goat rearing activities of the smallholders at rural level but the research reports on the productive and reproductive performances of goats in these GGDF are very limited. Objective: The main objective of this study was to evaluate the productive and reproductive performances of the BBG reared in semi-intensive system at the Rajshahi GGDF Materials and Methods: The Rajshahi GGDF had 398 goat populations of which 121 does were selected to study the productive and reproductive performances during the period from July 2010 to June 2011. The age of first estrus, conception rate by natural service, gestation length, post-partum heat, kidding interval, litter size, survivability of kids, morbidity and mortality of kids and their seasonal influence were studied. Results: The age of young female BBG showed 1st estrus varied from 180 to 270 with an average of 204  27 days. The conception rate varied from 88 to 100 with an average of 97% with natural services. The gestation length varied from 145 to 182 with an average of 150  5 days. The post-partum heat period varied from 60 to 90 days with an average of 69  7 days. The kidding interval varied from 199 to 268 with an average of 219  13 days. The litter size varied from 1 to 3 with an average of 2. Out of 234 kids borne, 47.44% were male and 52.56% female with higher mortality in male (10.81%) than female (5.69%) with an overall average mortality of 8.12%. There was no significant influence of season and parity on the birth weight of kids. However, the heavier birth weight of kids was recorded in male (1.38 kg) than female (1.17kg) kids. The birth of twin kids (56.41%) was found significantly (p < 0.0001) highest in comparison to triplets (26.92%), single (11.54%) and quadruplet (5.13%). Conclusions: The results support promising breeding and reproductive efficiency of BBG under local environmental conditions and therefore, there is a need to be improved milk yield of dam and control of morbidity and mortality in BBG kids. It may be concluded that the productive and reproductive performances of the BBG reared by using semi-intensive system of management appears to be encouraging at the Rajshahi GGDF which could be extended and compared to research findings with other four GGDF in Bangladesh.

The results of research on the use of the probiotic drug “Profort” in the diet of young pigs have been presented in the article. The research was carried out under the conditions of LLC “Agrofirma Ariant” on the crossbreds of young pigs. The purpose of the research was to study the eff ectiveness of the effect of the probiotic drug “Profort” in intensive pig rearing on the reproductive traits of sows and the productive traits of piglets. In order to conduct the scientific and economic experiment at the first stage, 2 groups of pregnant sows were formed in each with 10 heads. The feeding and housing of the experimental animals were the same. In addition to the main diet the sows of the experimental group were fed the probiotic additive “Profort” at the dose of 500 g/t of feed for 30 days before and 30 days after farrowing. At the second stage the resulting young animals were divided into 3 groups. In addition to the main diet the young animals of the 1st experimental group have been received the probiotic drug “Profort” from 7 to 105 days together with compound feed. Piglets of the 2nd experimental group have been received the probiotic additive from 7 to 30 days. It has been found during of studies that as a result of the use of probiotic additive the prolificacy of sows in the experimental group was higher – 10,6 compared to 10,4 heads in the control group. The livability of piglets for weaning in the experimental group was 97,9 % compared to 93,9 % in the control group. The absolute gain in live weight of piglets from 30 to 105 days in the experimental groups was 34,94–36,98 kg, which was higher than in the control group by 7,9–14,2 %. In the blood of piglets of the experimental groups, the increase in the level of red blood cells, total protein, calcium and phosphorus has been noted.

Egg Diameter

Currently, in many countries of the world, there is a positive dynamics of growth in the quail industry. When studying agricultural poultry, quails can serve as a model that characterizes all stages of bird growth, but in for the short period of time. Quails have been studied relatively recently, so there is the need to further study the productive traits of quails in order to have objective data when developing advanced technologies for the production of eggs and quail meat. Today in Russia for obtaining meat of quails, breeds of quail Pharaoh and Texas Whites use mainly. The development of scientific achievements opens up wide opportunities to increase the production of quail products and improve their quality Rearing quails with the right approach is even more cost-effective than rearing broiler chickens. The successful solution of problems in the rearing of quails depends largely on the results of scientific research. It was found according to previous studies that the trait “small egg diameter” is positively associated with the hatchability of eggs and the output of chicks. The purpose of this study was to determine the influence of selection by small egg diameter on the reproductive traits of the descendants of laying quails, their egg and meat productivity. The researches have been carried out at the Siberian Scientific and Research Institute of Poultry on quails of Pharaoh breed. The selection of quails based on the trait “small egg diameter” has led to the earlier sexual maturation by 3,2 days, the increase in egg production by 0,70 %, egg weight by 5,67 %, output of chicks by 5,60 %, live weight by 11,06 % (P < 0,001), average daily and absolute gain by 11,17 and 11,24 % (P < 0,001) and slaughter yield by 0,53–2,01 %.

The comprehensive evaluation of the productive traits of the initial genotypes of pigs in the creation of breeding herds using population selection methods has been carried out. Based on the results of evaluating the growth and development of breeding animals using the methods of index selection and DNA testing for the genes markers RYR1, ESR, IGF-2, MUC4 the genealogical structure of breeding herds has been formed on the basis of new stud lines of Belarusian stud type of pigs of Yorkshire breed. It has been found that sows of new lines had high reproduction rates: prolifi cacy was 11,6 piglets, milk capacity was 59,1 kg, number of piglets at weaning was 11,2 heads, and litter weight at weaning was 103,6 kg. The breeding herd of two new stud lines is represented by boars of the line Drug 6805 and Dobry 2313. The average productivity of boars-line continuers was: the age of reaching a live weight of 100 kg to 160 days, the average daily gain from birth to reaching the live weight of 100 kg was 636 g. At the age of 12 months, the live weight and body length of replacement boars were 268 kg and 175 cm, the thickness of the fat was 8,9 mm, the height of the longest back muscle was 51,5 mm, the content of lean meat in the body was 62,6 %, which corresponds to the class “elite”. Boars have been separated into reproductive traits. Improvement of lines is carried out through the continuators of related groups. Analysis of genetic studies of animals of new stud lines has shown that they have a high frequency of occurrence of desirable alleles by genes: RYR1 (stress-resistant animals) – 1,0; IGF-2 (fattening and meat traits) – 0,783; ESR (reproductive traits) – 0,608; MUC4 – (resistance to escherichiosis) – 0,786.

Reproductive traits and health status in dairy cows are largely affected by diet quality. Natural zeolite has been successfully used in livestock production as a feed supplement for some types and categories of domestic animals. This experiment was conducted over a period of 15 months involving Domestic Spotted dairy cows. The test animals were assigned to three groups, each receiving different levels of supplemental zeolite. The control group comprised cows that received no zeolite supplement. Experimental groups I and II were fed rations supplemented with 4% and 2% zeolite, respectively. The reproductive traits studied included gestation length, length of service period, length of calving interval, calf body weight at birth and calf body weight at 90 days of age. The results obtained suggest that zeolite supplementation affects some reproductive traits, depending on the zeolite level present in livestock feed.
