The Lebedyn breed of the combined direction of productivity was used for improvement of economically useful signs, especially milk productivity of cows of Brown Carpathian breed. Both breeds belong to the dual-purpose direction of productivity, they are adapted to the natural and climatic zones of breeding and "belong" to a related group of brown breeds. The largest related group of the Brown Carpathian breed are the descendants of the bull Rupora 6507, to which the "single crossing" of the Lebedyn breed of the dual-purpose direction of productivity was carried out. In addition, the following servicing bulls of the Lebedyn breed were used to improve the economically useful characteristics of the Brown Carpathian breed: Tuman 779 Shafran 2012, Henii 958, Kokos 923 (related group of Elbrus 1871) Zhdanyi 035, Limonad 2188, (line of Narzan 937) Landysh 2012 (related group of Rolik 113) Minus 1353 (line of Fordzon-Mylyi 290). The Lebedyn breed has played an important role in strengthening the productive characteristics of Brown Carpathian breed and expanding its genealogical structure.

ABSTRACTFor the Mpwapwa cattle breed in Tanzania, the efficiency of various breeding schemes including an open nucleus was investigated by model calculations. Artificial insemination and intensive recording of production are assumed to be applied in a nucleus which is the main breeding unit. As a pre-nucleus, associated herds with less intense data recording serve as the basis to screen superior cows for nucleus replacements, provide the capacity for progeny testing, and operate as bull multipliers for commercial herds.The criteria of efficiency were genetic gain and profit from selection for a dual purpose breeding objective (milk and beef) in a total population of 10 000 cows. Introducing a two breeding tier scheme through separating all recorded cows into a nucleus and pre-nucleus leads to an increase of the genetic gain rather than the profit. Further improvement is obtained by introduction of artificial insemination in pre-nucleus herds. The nucleus size should not exceed about 5% of the cow population and an optimum size of the pre-nucleus is about 15%. Opening the nucleus to replacement cows coming from the pre-nucleus affects the aggregate genetic gain very little although it can be recommended if milk yield is to be mainly improved or if the total profit is taken into account. Furthermore, the nucleus should be opened if there is little difference between the heritabilities in the nucleus and pre-nucleus and also in order to avoid detrimental effects of inbreeding and genotype × environment interaction.

SUMMARYPolish Red is the only indigenous cattle breed in Poland. Breeding was first started at the end of the 19th century. At the end of the 1960s the breed constituted more than 20 percent of the total cattle population in Poland. During the 1970s Polish Red cattle were superseded by Friesian,-and now there are about 200 000 cows left (i.e., 3 percent of the total population).These dual-purpose (dairy-beef) animals are hardy and well adapted to rather poor feeding conditions. An improvement programme, through crossbreeding, would likely diminish their original characteristics. Therefore, together with breed improvement, a gene reserve in the form of a conservation herd of 300 cows and a gene bank of frozen semen and embryos have been implemented. A systematic breeding programme has been implemented also to maintain the old genotype and ensure wider genetic variation within the herd.

Abstract Russian Ayrshire population of cattle is the second largest in number the world population of animals of this breed. Trimethylaminuria (TMA) is the monogenic disease manifesting in the ‘‘fish off-flavor” of the milk from the sick cows and caused by R238X mutation in the flavin-containing monooxidase 3 gene (FMO3). The aim of our investigation was the analysis of the FMO3 gene polymorphism of Ayrshire cattle breed and its relationship with the milk productivity of the first lactation. The analysis of FMO3 gene polymorphism has been carried out on 352 animals of 5 herds, and associations with the milk productivity due 305 days have been evaluated on 20 healthy cows (RR) and 6 ones-carriers of the mutation (RX). DNA has been extracted by means of the kit “DNA-Extran” (“Syntol”, Russia). The identification of the FMO3 genotypes has been conducted by PCR-RFLP in according to the previously developed method with using TaqI restriction endonuclease. The frequency of animals-carriers of X allele associated with the defect of “fish off-flavor” of milk was in the range 10.21–12.82%. The frequencies of RR, RX and XX genotypes were 76.9, 20.5 and 2.6 %, respectively. The study of relationship between the genotypes on FMO3 gene and productivity traits has shown that the homozygous RR-individuals in comparing to RX-ones had significantly higher levels of the milk yield (+918.6 kg, P ≥ 0.05) and content of the milk protein (+28.8, P ≥ 0.05). Adaptive abilities of RR-cows of Russian selection allowed them to surpass animals of Finnish origin with a similar genotype in milk yield 5,655.6 ± 254.2 against 5,105.0 ± 238.6 kg. The investigations has shown the significant superiority the animals-non carriers of the “fish off-flavor” defect in the milk yield and content of the milk protein.

Baladi, (B taurus; DAGRIS) a native cattle breed found throughout the entire Southern Mediterranean basin, is known for its high disease resistance and hardiness. Baladi cows in Israel and Southern Mediterranean basin are endangered due to the introduction of larger and more productive European breeds in these regions. In order to promote conservation initiatives of Baladi by stakeholders, the yet unexplored production traits, over their well accepted adaptation to the harsh Mediterranean conditions, were sought in the current study. Aiming at locating the genetic potential of Baladi for meat quality, the allelic and genotypic frequencies of four polymorphisms in CAST, CAPN1, DGAT1, and FASN genes, previously reported to be associated with meat quality traits, were compared to four cattle breeds. The other four breeds included Limousine, Holstein, Simmental and Brahman cattle, which represent beef, dairy, dual-purpose and indicine bovine members, respectively. Relative to the four bovine members, Baladi cattle exhibited high frequencies of the increasing alleles and genotypes in all four SNPs associated with meat tenderness or fat deposition. These findings, along with future phenotyping and genomic profiling of meat quality related markers, and the well-established adaptability to the challenging Mediterranean pasture conditions, may promote conservation initiatives of Baladi cattle by stakeholders.

The present study was carried out in Deoni, the dual purpose cattle breed of Southern India, maintained at NDRI herd, SRS, Bengaluru. Mean phenotypic performances for the traits of age at first calving (AFC), first service period (FSP), first lactation milk yield (FLMY) and first lactation length (FLL) were estimated as 42.90 ± 0.49 months, 179.00 ± 6.3 days, 643.08 ± 25.16 kg and 178.24 ± 4.41 days respectively. Significant effect of parity was found on AFC and FSP. Effect of period of birth, period of calving and season of calving was found to be significant on FSP. Significant effect of period of birth, period of calving, classes of AFC and FLL were found on FLMY. The heritability of first lactation milk yield was estimated as 0.38 ± 0.29. Phenotypic correlation of FLMY with FLL (0.88 ± 0.02) was found to be highly significant (p Lass Than 0.01).

SUMMARYThe degree of inbreeding was studied for a subpopulation of the beef cattle breed Retintofrom the Cadiz Province in Andalusia (Spain). The pedigree information from 492 female and 25 male breeding animals was analyzed. On the basis of the available information, only the current inbreeding, that is the inbreeding with consideration of three ancestral generations, could be calculated. While close inbreeding is purposely avoided with the bulls, it is of great importance in cows. The average coefficient of inbreeding for cows born inthe years 1982 to 1987 was o 2.35 /;o, although in the great-grandparent generation only 55% of the ancestors were known. Inbreeding was discovered in 17.7% of the cows; 5.8%of the cows had an inbreeding coefficient of 25%. The rate of inbreeding per generation is very high in comparison with other beef cattle breeds and above all in comparison with dual purpose cattle. Because of the manner in which the bulls are used, also considerablenon-current inbreeding has to be expected.

Recently, a Total Merit Index (RZ€) has been developed for German Holstein dairy cattle on the basis of margin in Euro. Our aim was to adjust this lifetime net merit for the dual-purpose German Black Pied cattle breed (DSN) accounting for beef production in addition to milk performance and fitness traits. We used the estimated breeding values of DSN sires and developed a breeding value for carcass weight and quality. Furthermore, we adjusted the German Holstein marginal profits per standard deviation, which are used to calculate the estimated breeding values, to DSN-specific values. The DSN Net Merit is the sum of the three sub-indices DSN Net Milk, DSN Net Fitness, and DSN Net Beef, which contribute to the DSN Net Merit with 52.84%, 43.43%, and 3.73%, respectively. The DSN Net Merit that was calculated for 33 DSN sires ranged between EUR −1114 and +709. The DSN Net Merit strongly correlates with the Total Merit Index. The implementation of the DSN Net Merit is useful for selection and mating decisions. Especially, the sub-index DSN Net Beef, which does not correlate with existing breeding values, can be used to maintain the dual-purpose character of DSN while modestly improving milk yield. The approach can be easily adapted to other dual-purpose breeds.

The study of age-related milk productivity in the breeding cattle enables to determine the duration of their use and adaptability to the technological conditions. According to the investigations conducted on the farm of “Vamax” LLC, the high index of milk productivity in the Fleckvieh cattle breed is related to sufficient acclimatization capacity and the expansion of their economic use span. Thus, the inclusion of longevity factor among the other breeding peculiarities would promote the stock increase in the cows of 5th and 6th calving (5th and 6th lactation) with high milk productivity. It is recommended to implement the introduced technology in the farms where Fleckvieh cows are bred.
