SUMMARYThe authors describe the history, evolution and actual situation of Estonia's two only remaining autochthonous breeds of farm animal namely the Estonian Native Cattle (577 cows in milk production in 1992) and the Estonian Native Horse (271 purebred horses). This is actually mainly found in the island of Saaremaa, where a nucleus of 211 purebred horses exists. The interest in the Estonian Native Cattle breed is growing since the creation in 1989 of an active Breeders' Association and many farmers applying less intensive production systems and farm management techniques prefer now this breed to the more productive Black and White and Estonian Red cattle. The situation of the Estonian Native Horse is much more fragile, as a clear breeding and conservation programme is needed to save this unique genetic material.

SummaryA survey was conducted in order to investigate what motives farmers have to utilize one of the old, native cattle breeds in Norway, Blacksided Trønder and Nordland Cattle (STN). The questionnaire, which was sent to 1 772 farmers who inseminated with the STN breed from 1987 to 1997, revealed clear opinions on the differences between this breed and the predominant breed of the country, the Norwegian Cattle (NRF).The farms in the survey were characterized by having herd sizes above the national average, as well as having owners interested in extensive farming and to a certain extent aware of the special breeding challenges of small populations. The results showed that the STN breed was regarded as being significantly different for traits that may be considered as important in extensive production systems. The more idealistic motives linked to the genetic resources aspect showed a high priority.The survey also revealed an obvious need for more research and objective information about this old native breed.

In this paper current situation is analyzed and sustainable systems introduced in production of milk on small farms. Old production systems used on farms were the reason why milk production wasn't profitable activity and therefore livestock production in mountainous regions had complete collapse and pastures remained almost entirely deserted. In population of Pirot Pramenka sheep and local Simmental population of cattle, our analysis of breed productivity shows that effects in milk production are bad. Application of sustainable systems of milk production would increase the milk yield and revive dairy livestock production. After application of new systems regarding of breeding and farm management, milk yield in sheep cows was increased in average by 12%.

Introduction. The main direction of increasing the productivity of milk is to increase the proportion of heredity of the Holstein breed in the genotype of cows. Industrial breeds in Ukraine are improving due to the increase in the Holstein inheritance in the genotype of cows. The "holsteinization" of the most widespread domestic Black-and-White diary breed is intensively conducted. Currently, the percentage of heredity from Holstein is 90% or more. The negative effect of "holsteinization" appeared in reducing the resistance of animals to diseases that led to the spread of necrobacterial pathology. The control of the spread of necrobacteriosis can be based on genetic markers. Important markers can be the allele of the BoLA-DRB3.2 gene responsible for the formation of adaptive immunity. Due to the ambiguity of the results of "holsteinization", the following tasks were solved: To study the genetic structure of the herd for the BoLA-DRB3.2 gene at the beginning of the "holsteinization" and now. To compare the detected genetic structures with the alleles spectrum of North American Holstein and identify quantitative and qualitative changes in the structure of the herd genotype. To determine the effect of "holsteinization" on the dynamics of milk production and the state of morbidity by necrobacteriosis. Materials and methods of research. Comparison of alleles of population of the Ukrainian Black-Pied Dairy (UBPD) breed and Holstein breed was conducted to detect the consequences of "holsteinization" on milk yield and incidence of necrobacteriosis. The data of the allelic polymorphism of the BoLA-DRB3.2 gene of the UBPD10 (2010, n = 162), UBPD15 (2015, n = 114) and two Holstein populations of the USA and Canada were collected. The allelic spectrum was determined by the PCR-RFLP method. The amplification of the BoLA-DRB3.2 gene was performed using 2-step PCR with the use of primers HLO-30, HLO-31 and HLO-32 and allele-specific PCR. Restriction analysis was performed with endonuclease RsaI, HaeIII, BstYI (XhoII). Restriction fragments were separated by electrophoresis in 4% agarose gel. Counting of allele frequencies was performed taking into account the number of homozygotes and heterozygotes found for the corresponding alleles. To determine the phylogenetic relationships between the populations of the studied herds, genetic distance and genetic similarity were determined by the M. Nei method. Individual dairy productivity of cows was estimated for all lactation (regardless of its duration). Average milk yields were determined as the total volume of milk produced divided by the number of dairy cows. Results and discussion. The breeding measures carried out led to the accumulation of alleles characteristic of the Holstein breed. For Holstein, there are eight alleles with a frequency of more than 4%. It is alleles *03, *07, *08, *11, *16, *22, *23, *24. A high degree of consolidation of weighty alleles can be outlined. In total they occupy 84,6% of allele spectrum of the population. Consolidation of such alleles in the herd of the Ukrainian Black-and-White diary breed is much lower - only 52.2%, although it increased by 6.2% over 5 years. Alleles *10, *13 and *28 are "weighty" for the Ukrainian Black-and-White diary breed, but they are almost non-existent in Holsteins. The genetic similarity of the herd UBPD15 and Holstein increased by ΔI = 0,085, and the genetic distance between the herds of the UBPD increased by ΔD = 0,085 for 5 years. The comparison of the allele spectrum of Holstein and the Ukrainian Black-and-White diary breed shows both the accumulation and the elimination of alleles associated with high productivity. The largest consolidation is typical for alleles *24 (+ 6.75%) and *16 (+ 4.65%). The frequency of "milk" alleles *22 and *08 decreased, respectively, by 4.14 and 1.27%. Alleys, which cause low milk productivity, have the following dynamics: * 23 + 2.53%, *11 – 0.67 and *28 – 0.26. The accumulation of alleles *16 and *23 (7.18%) was found that are associated with predisposition to necrobacteriosis and elimination of *03 and *22 alleles (4.75%) that influence on this disease. Conclusions. It is determined that the role of alleles characteristic for Holstein is increasing in the the Ukrainian Black-and-White diary herd. Breeding measures for holsteinization are conducted in the right direction. There is accumulation of alleles associated with high milk productivity and predisposition to necrobacteriosis. It positively affects the growth of milk production and negatively affects the incidence of necrobacteriosis.

In the Republic of Kazakhstan over the past decade positive changes have been observed in increasing the number of farm animals, increasing their productivity, and increasing the gross production of milk, meat and other products. At the same time the development of dairy cattle breeding is mainly due to the breeding of Black-and-White, Red Steppe, Simmental breeds and their intra-breed types as well as imported from abroad Holstein breed. The purpose of the research was to analyze ways to improve the intra-breed type Karatomar of Black-and-White breed in Northern Kazakhstan. Research work has been carried out on breeding animals such as Karatomar type cattle of Black-and-White breed in LLP “Experimental farm Zarechnoe” in the Kostanay district in the Kostanay region. The dynamics of growth and development indicators, reproductive traits of heifers of a new intra-breed type Karatomar of Black-and-White cattle have been studied. A comprehensive assessment of their economically useful traits in the first lactation, determined by the resistance of animals to climatic and forage conditions, the efficiency of breeding of animals of different genotypes has been conducted. It has been found that the replacement heifers – daughters of American breeding sires inherited precocity and showed higher growth energy after 6 months of age and continued to grow rapidly until 18 months. The advantage in metabolism was in the daughters of Holstein sires of the American selection Orbit 4078, and the increased immune status of the organism in the daughters of the sire of the domestic selection Yamal 975 as the most adapted to the conditions of Northern Kazakhstan. The best ability to increasing the milk yield, stable lactation activity, high milk productivity, gross content of dry matter and nonfat milk solids have been characterized by the daughters of sires of the American selection Orbit 4078 and Lowrider 4129. Analysis of economic indicators of milk production has been shown that from cows – daughters of sires Orbit 4078 and Lowrider 4129 for 305 days of lactation received 15,8 and 15,2 % more milk of base fat, the expenditures of EFU per 1 kg of production was lower by 10,2 and 5,9 %. A higher level of profitability has been observed in the group of daughters of the sires Orbit 4078 – 35,5 % and Lowrider 4129 – 33,1 %, which was 8,5 and 10,8 % higher than in the group of daughters of the sire Yamal 975.

Abstract Our objective was to determine the content of the bioactive protein osteopontin (OPN) in bovine milk and identify factors influencing its concentration. OPN is expressed in many tissues and body fluids, with by far the highest concentrations in milk. OPN plays a role in immunological and developmental processes and it has been associated with several milk production traits and lactation persistency in cows. In the present study, we report the development of an enzyme linked immunosorbent assay (ELISA) for measurement of OPN in bovine milk. The method was used to determine the concentration of OPN in milk from 661 individual Danish Holstein cows. The median OPN level was determined to 21.9 mg/l with a pronounced level of individual variation ranging from 0.4 mg/l to 67.8 mg/l. Breeding for increased OPN in cow's milk is of significant interest, however, the heritability of OPN in milk was found to be relatively low, with an estimated value of 0.19 in the current dataset. The variation explained by the herd was also found to be low suggesting that OPN levels are not affected by farm management or feeding. Interestingly, the concentration of OPN was found to increase with days in milk and to decrease with parity.

In a previous short term study, Ferris et al. (1997) demonstrated that similar levels of nutrient intake and animal performance could be obtained by either increasing silage feed value and reducing concentrate feed level, or by reducing silage feed value and increasing concentrate feed level. The principles established in this study were incorporated into this trial to examine two systems of milk production over a full lactation, including both the winter and grazing periods.Forty high genetic merit dairy cows (PTA95 fat + protein = 38.2 kg), in their second or subsequent lactation, were used in a continuous design full lactation study. Animals had a mean calving date of 1 November and were allocated to one of two systems of milk production, HF or HC, within 36 hours of calving. During the winter, animals on system HF were offered a silage with high feed value characteristics, supplemented with 5.5 kg of concentrate (crude protein concentration of 280 g/kg DM) through an out-of-parlour feeding system.

Farmlets, each of 20 cows, were established to field test five milk production systems and provide a learning platform for farmers and researchers in a subtropical environment. The systems were developed through desktop modelling and industry consultation in response to the need for substantial increases in farm milk production following deregulation of the industry. Four of the systems were based on grazing and the continued use of existing farmland resource bases, whereas the fifth comprised a feedlot and associated forage base developed as a greenfield site. The field evaluation was conducted over 4 years under more adverse environmental conditions than anticipated with below average rainfall and restrictions on irrigation. For the grazed systems, mean annual milk yield per cow ranged from 6330 kg/year (1.9 cows/ha) for a herd based on rain-grown tropical pastures to 7617 kg/year (3.0 cows/ha) where animals were based on temperate and tropical irrigated forages. For the feedlot herd, production of 9460 kg/cow.year (4.3 cows/ha of forage base) was achieved. For all herds, the level of production achieved required annual inputs of concentrates of ~3 t DM/animal and purchased conserved fodder from 0.3 to 1.5 t DM/animal. This level of supplementary feeding made a major contribution to total farm nutrient inputs, contributing 50% or more of the nitrogen, phosphorus and potassium entering the farming system, and presents challenges to the management of manure and urine that results from the higher stocking rates enabled. Mean annual milk production for the five systems ranged from 88 to 105% of that predicted by the desktop modelling. This level of agreement for the grazed systems was achieved with minimal overall change in predicted feed inputs; however, the feedlot system required a substantial increase in inputs over those predicted. Reproductive performance for all systems was poorer than anticipated, particularly over the summer mating period. We conclude that the desktop model, developed as a rapid response to assist farmers modify their current farming systems, provided a reasonable prediction of inputs required and milk production. Further model development would need to consider more closely climate variability, the limitations summer temperatures place on reproductive success and the feed requirements of feedlot herds.
