The general aim of the present work was to compare dairy performance and some reproductive parameters of Holstein-Friesian (HF) cows imported from Sweden as an in-calf heifers, and their age mates in Poland. The animals were kept freely on the deep litter on the farm owned by Agro-company “Witkowo” and feeding was based on TMR (total mixed ration) system during whole year. All ration’s ingredients (bulky feed, concentrate, miscellaneous additives) were mixed and fed as all-mash. The feed ration depended from the physiological condition of a cow and it was composed of corn and grass ensilage, mash concentrate, crushed corn meal, brewer’s grains and beet pulp.Cows imported from Sweden as in-calf heifers obtained higher milk, fat and protein yield in both lactations comparing to home cows. Significant statistical differences were observed for kg of milk, kg of protein, for FCM (P<0.01) and for kg of fat (P<0.05) in 2nd lactation. Fat and protein content in milk was in average higher for home cows (P<0.01). Big differences (P<0.01) were observed in SBT (proportion of protein to fat content) and RTB (difference between concentration of fat and protein) at imported cows in 2nd lactation. As far as reproduction parameters (gestation interval, calving interval, insemination index) are concerned was cows from Sweden better too. Heifers from Sweden calved earlier. The usage of high genetic potential of imported cows is possible only with providing them optimum living conditions suitable to their needs.

The Impact

The research was performed on Holstein-Friesian and Black and White bull dams reared on five farms of Agricultural Corporation of Belgrade - PKB. The study included 575 lactations of cows selected as bull dams and their progeny calved in the period from 2007 - 2014 and represent progeny of 24 bulls. The following dairy traits were analysed in a standard lactation (305 days): milk yield (kg) - MY, milk fat content (%) - % MF, milk fat yield (kg) - MFY, protein content (%) - % PC and protein yield (kg) - PY. Holstein-Friesian bull dams and their progeny, in standard lactation, produced on average 9239.84 ? 1607.64 kg of milk, with a milk fat content of 3.44 ? 0.20 and protein content of 3.21 ? 0.12. The impact of bull - sire, year of birth, lactation order, farm, year and calving season was present at different levels of statistical significance on yield traits, while the genetic group had no influence on any of the milk traits. Bull - sire, year of birth, lactation order and calving season did not influence the variability of milk fat and protein content. Heritability of observed milk traits was medium to low. The content of milk fat and protein had the lowest values of heritability, 0.014, and 0.024, respectively. The heritability of milk yield, milk fat yield and protein yield was 0.293, 0.319 and 0.273, respectively.

The characteristic of milk productivity of cows of Holstein and Simmental breeds in LLC “Sibirskaya Niva” in the Maslyaninsky district in the Novosibirsk region has been given. It has been revealed that under the natural and climatic environments of the Western Siberia, when creating favorable conditions for feeding and housing for cows of Holstein and Simmental breeds have sufficiently high milk productivity. It has been found that Holstein first-calf heifers surpassed their Simmental herdmates by 959 kg in milk yield for the first 305 days of lactation under the same conditions of housing and feeding, by 3,1 kg in daily milk yield, by 38,2 kg in milk fat yield, and by 28,3 kg in milk protein yield (P < 0,001). There were no statistically significant differences between animals of Holstein and Simmental breeds in terms of fat and protein content in milk, which amounted to 3,94 and 2,96 % in Holstein breed and 3,97 and 2,98 % in Simmental breed, respectively. Both breeds have shown high milk productivity during the first 3 lactations. Thus, the milk yield of Holstein cows for the first 3 lactation was 6475–9290 kg, Simmental cows it was 5516–7680 kg, fat content was 3,93–3,99 and 3,96–3,97 %, respectively. The protein content in the milk of cows of both breeds did not exceed 3,0 %. High variability has been found in milk yield, yield of milk fat and protein, the coefficient of milk content and duration of lactation, the lowest in the content of protein and fat in milk and live weight. The correlation coefficients between the fat and protein content in milk were generally positive, but did not exceed 0,28. Therefore, breeding in the herd of cows in LLC “Sibirskaya Niva” have to be conducted not only by fat content, but also by protein content in milk.

In order to examine the variability of production performance traits (lactation duration, milk yield for the whole lactation, milk yield in standard lactation, milk fat content, milk fat yield in standard lactation, protein content and yield in standard lactation), 954 cows, domestic and imported Simmental populations, were included in the study, with a total of 3641 completed lactations. Cows were located in the area of Toplica district, reared on individual farming households (tied system) and on the farm with intensive farming (free system). Based on the rearing method and origin, animals were divided into four groups: Group 1 (domestic animals reared by individual agricultural producers on individual farming households); Group 2 (imported animals reared by individual agricultural producers on individual farming households); Group 3 (domestic animals reared on the farm) and Group 4 (imported animals reared on the farm). The fourth group of studied cows showed the highest yield and protein content, while the cows of the third group had the longest lactation and the highest milk fat content. All production performance traits varied highly significantly (p?0.001) under the influence of the combined factor of housing/rearing method and origin.

Morning Milk

Milk yield varies during lactation, following what is termed a lactation curve. ŽIŽLAVSKÝ and MIKŠÍK (1988) recorded changes in milk yield within a day, too. TEPLÝ et al. (1979) a KOUŘIMSKÁ et al. (2007) published variation within a day ± 1.10 kg in milk yield, ± 0.75 % in milk fat content and ± 0.20 % in milk protein content. Milk yield of cows can be expressed in many different ways, for instance, in kilograms per lactation or in kilograms per day. A practical parameter describing milk production is milk yield (kg) per milking.The object of experiment were 12 cows of Holstein cattle on the first lactation from the 100-day of lactation to 200-day of lactation. The samples of milk were collected from January to May 2007, once a month from the morning and evening milking (milking interval 12 h ± 15 min.). The following parameters were monitored: milk production – milk yield (kg), milk protein production (kg), milk fat production (kg); milk composition – milk protein content (%), milk fat content (%), lactose content (%), milk solids-not-fat content (%), milk total solids content (%); technological properties of milk – ti­tra­tab­le acidity (SH), active acidity (pH), rennet coagulation time (s), quality of curd (class) and somatic cell count as a parameter of udder health.Highly significant differences were found (P < 0.01) between morning milk yield (15.7 kg) and evening milk yield (13.8 kg), between morning milk protein production (0.51 kg) and evening milk protein production (0.45 kg) and between evening milk fat content (4.41 %) and morning milk fat content (3.95 %). A significant difference (P < 0.05) was found between morning milk total solids content (12.62 %) and evening milk total solids content (12.07 %). No significant differences were found between morning (M) and evening (E) values of the remaining parameters: milk fat production (M 0.62 kg; E 0.60 kg), milk protein content (M 3.24 %; E 3.27 %), milk lactose content (M 4.78 %; E 4.86 %), milk solids-not-fat content (M 7.69 %; E 7.71 %), somatic cell count (M 80 000/1 mL; E 101 000/1 mL), titratable aci­di­ty (M 7.75 SH; E 7.64 SH), active acidity (M pH 6.58; E pH 6.61), rennet coagulation time (M 189 s.; E 191 s.), quality of curd (M 1.60 class; E 1.57 class).

The solute carrier family 27 member 1 (SLC27A1) is an integral membrane protein involved in the transport of long-chain fatty acids across the plasma membrane. This protein has been implicated in diet-induced obesity and is thought to be important in the control of energy homeostasis. In previous reports, our group described the isolation and characterization of the bovineSLC27A1gene. The bovine gene is organized in 13 exons spanning over more than 40 kb of genomic DNA and maps in BTA 7 where several quantitative trait loci for fat related traits have been described. Because of its key role in lipid metabolism and its genomic localization, in the present work the search for variability in the bovineSLC27A1gene was carried out with the aim of evaluating its potential association with milk fat content in dairy cattle. By sequencing analysis of all exons and flanking regions 14 new single nucleotide polymorphisms (SNPs) were identified: 1 in the promoter, 7 in introns and 6 in exons. Allele frequencies of all the SNPs were calculated by minisequencing analysis in two groups of Holstein-Friesian animals with highest and lowest milk-fat content estimated breeding values as well as in animals of two Spanish cattle breeds, Asturiana de los Valles and Menorquina. In the conditions assayed, no significant differences between Holstein-Friesian groups were found for any of the SNPs, suggesting that theSLC27A1gene may have a poor or null effect on milk fat content. In Asturiana and Menorquina breeds all the positions were polymorphic with the exception of SNPs 1 and 8 in which C allele was fixed in both of them.

The paper presents results of studies on evaluating Simmental cows for machine milking suitability. It was found that 78.7% of cows had a bowl-shaped udder, round - 14.7% and goat - 6.6% of cows at ‘agricultural production cooperative “COMBINE”. Bowl-shaped cows are more productive. Their milk yield was 4724 kg for 305 days of lactation with a fat content of 3.97% and a protein content of 3.30%. Their udder index was 47.7%. As for cows with a rounded udder shape, milk yield per lactation was 4246 kg with fat and protein content of 4.08 and 3.26% , respectively, and an udder index of 46.1%. Cows with a goat udder shape were characterized by low milk yield (3181 kg) and the worst parametres of milk fat content (3.88%), milk protein (3.20%) and udder index (2.2%). Approximately the same pattern is observed in the herd of the agricultural cooperative “Abodimovskiy” with slightly worse parametres of cow productivity. The intensity of milk production of cows of agricultural production cooperative “Abodimovsiy” with a bowl-shaped udder was 1.42, round - 1.35 and goat - 1.18 kg / min. Cows with a rounded udder shape had higher milk flow rate, which was equal to 1.65 kg / min, with a bowl-shaped one - 1.24 and with a goat udder shape- 1.09 kg / min in agricultural production cooperative “Combine”. No relation was found between udder index and milk composition. There is also no conjugation between the intensity of milk flow and fat and protein content for udder quarters and for the udder as a whole, whereas a positive correlation was found between the intensity of milk flow and daily milk yield.

Приведены результаты оценки быковпроизводителей голштинской породы по молочной продуктивности и воспроизводительным качествам их дочерей. Обработаны данные 563 первотелок и 45 быковотцов. В среднем удой дочерей за 1ю лактацию от разных отцов колебался от 6784 до 7789 кг, по содержанию жира и белка в молоке различий не выявлено. Большинство производителей обладали желательной степенью реализации генетического потенциала. Основной вклад в генетическое совершенствование стада вносят быки Altahessel Sex138929389, Altajupiter Sex 66011448 и ClearEc Altar2 62916235, достоверно увеличивая удой дочерей за 305 дней 1й лактации от 350 кг до 490 кг по сравнению со средними показателями по стаду. Уровень раздоя коров по 1й лактации достоверно обусловливает их дальнейшую продуктивность. У дочерей ClearEc Altar2 отмечена положительная корреляция (0,44) между удоем и белком, а у дочерей Бодо 354239752 (r0,68) между жиром и белком. Отмечены дочери с отрицательной коррелятивной связью между удоем и жиром, это свидетельствует о том, что в этих группах с высокой молочной продуктивностью отбор коров по жирномолочности не обеспечивает повышение белковомолочности. Самый короткий сервиспериод (98 дней) характерен для дочерей Магикон 536522893, наиболее длинный у дочерей Dinom Altatyson 66133528 и Short Cut 3504510619. Используемые быкипроизводители в хозяйстве реализуют свой потенциал в более сжатые сроки, что необходимо учитывать при дальнейшем их закреплении.The results of estimation of Holstein sires based on milk productivity and reproductive qualities of their daughters are presented .The findings of 563 heifers and 45 bullsfathers were processed.on average, the milk yield of daughters for 1 lactation from different fathers ranged from 6784 to 7789 kg, theee were not found any differences in the content of fat and protein in milk.most producers had a desirable degree of realization of genetic potential. Bulls Altahessel Sex138929389, Altajupiter Sex 66011448 and ClearEc Altar2 62916235mainly contribut to the genetic improvement of the herd, significantly increasing yield of daughters in 305 days of the first lactation from 350 kg to 490 kg compared to the average for the herd. The level of milking cows on the 1st lactation reliably determines their further productivity. Daughters of ClearEc Altar2 had a positive correlation (0.44) between milk yield and protein, and daughters of Bodo bull 354239752 (r0.68) between fat and protein. Daughters with a negative correlation between milk yield and fat were noted, this indicates that the selection of cows by fat content does not provide an increase in protein content in these groups with high milk productivity. The shortest service period (98 days) are typical for daughters of Magikon 536522893, the longest the daughters Dinom Altatyson 66133528 and Short Cut 3504510619.sires, used in farming, realize their potential in a shorter time, which should be taken into account in their further consolidation.

The share of genes of Holstein breed was 76.8% in the herd. It was found that during the research period, the normal distributions of milk productivity traits were observed in the herd. The number of cows in the herd decreased, but their breeding qualities increased. The main reason for which animals were culled from the herd was their gynecological diseases (in some years, up to 175 to 188 heads were culled). The protein content in milk varied from 2.90 to 3.39%. Most cows produced milk in which the protein content was at a level of 3.00 to 3.19%. The herd showed positive correlations between the yields of mothers and daughters for the 305-day-long period: 0.234 for the whole herd, 0.517 for the group of cows with 50% of Holstein breed (HF) genes, 0.098 for the group with 51-75% of HF genes, and 0,189 for the group with minimum 76% of HF genes. For the herd, the heritability coefficient for milk yield for the 305- day-long period (h2) was 0.468. The percent of the protein content in milk produced by cows with 50% of Holstein genes had a high heritability coefficient of 0.668. Only cows of the M. Chieftain line showed positive correlations between the fat content in milk produced by mothers and daughters, and positive correlations between the protein content in milk produced by cows of the W. B. Ideal and M. Chieftain lines was found. With an increase in percent of Holstein breed genes (HF) from 25 to 75% and more, there were no significant differences in milk yield among first-calf cows (they amounted to 5,424 ± 83 – 5,520 ± 116 kg of milk). The percentage of fat and protein in milk for the whole herd was positively interconnected (r = + 0.460). On average, daughters exceeded their mothers by 23.3% in terms of milk yield and by 2.0% in terms of the percentage of fat content in milk (of the trait value). The quantity of milk fat and protein increased by 25.8 and 22.5%, respectively. Based on the research results, it has been concluded that the Holstein breed has a positive effect on the productive traits of dairy cattle, but technology optimization is required to continue selection activities.

The milk composition responses in five feeding trials were as follows.1. A study of silage quality showed that the fat content was lower (39.9 v. 43.1 g/kg, s.e. of difference 1.00) and the protein content was higher (35.0 v. 33.7 g/kg, s.e. of difference 0.48) with silage cut three times per season compared with silage cut twice per season.2. Silage offered as a buffer food overnight in the early part of the grazing season reduced milk yield (18.9 v. 19.9 kg/day, s.e. of difference 0.26) and increased fat content (39.4 v. 35.6 g/kg, s.e. of difference 0.50) when compared with grazing only. Silage offered in the late grazing season did not affect milk yield but increased fat content(44.1 v. 41.3 g/kg, s.e. of difference 0.94). There was no significant effect on protein content.3. A concentrate containing 18 g crude protein/kg was offered at rates of 0.30, 0.375 and 0.45 kg/kg milk plus silage ad libitum. The fat contents were 38.0, 38.6 and 36.1 g/kg and the protein contents 30.3, 31.2 and 32.1 g/kg, respectively.4. In two experiments comparing flat-rate concentrate feeding with feeding according to yield, no significant differences were found in milk yield, fat and protein contents.5. In a study of body condition at calving, cows calving at score 2 had milk fat contents similar to cows calving at score 3 but there were differences in the fatty acid composition of the milks. The cows calving at score 2 produced milk with a higher protein content than those at score 3 (32.8 v. 30.7 g/kg, s.e. of difference 0.85).
