SummaryComparative study was conducted at Alage and Ardaita Agricultural Technical and Vocational Education Training College dairy farm to evaluate the reproductive performance of Holstein Friesian (HF) and associated factors in the two farms. The data collected from 2000 to 2015 on reproductive traits (n= 1688) were analyzed using general linear model procedures of SAS version 9.2 (SAS, 2008). The result revealed that an overall least square means and standard errors for Age at first Service (AFS), Age at first calving (AFC), Calving interval (CI), Days open (DO) and Number of services per conception were 29.70 ± 0.49 months, 39.75 ± 0.53 months, 465.76 ± 7.22 days, 188.11 ± 7.22 days and 1.31 ± 0.04, respectively. AFC was significantly influenced by agro ecology (P< 0.001) and year of birth (P< 0.01). Besides this, agro ecology (P< 0.001) and year of birth (P< 0.05) was significantly influenced by AFC. Year of calving and parity had significant effect (P< 0.001) on CI and DO. Except CI, agro ecology had significant effect on all traits. Service per conception was significantly influenced by agro ecology (P< 0.05) and year of calving (P< 0.01). Season of birth and season of calving was not significant on all reproductive traits. Except SPC, the result obtained for AFS, AFC, CI and DO were below the standard expected from commercial dairy farm. Poor efficiency of estrus detection and expression were the most probable management factors accounted for longer period of AFS, AFC, CI and DO. Improving the level of nutrition as well as efficiency of estrus detection system is required for optimal reproduction performance of HF breed in the area.

Abstract Objective To assess the efficacy of antibiotic usage for the treatment of puerperal metritis (PM) and its association with reproductive performance, a retrospective cohort study including a total of 9168 records of cows from a dairy farm in Argentina was run. Material and methods Cows having a PM3 (metricheck, scale 0–3) and treated with ceftiofur (ceftiofur crystalline free acid, 6.6 mg/kg) at 0–21 days postpartum (p. p.) (n = 2688), and cows having a PM 1–2 and not treated with an antibiotic at 0–21 days p. p. (n = 6480) were included in the study. All cows were reexamined with metricheck to assess the clinical cure (vaginal discharge [VD] score 0), partial cure (VD score similar or lower than previous), no cure (VD score higher than previous). Cows with a metricheck VD1–3 after 0–21 days p. p. were diagnosed as clinical endometritis (CE) 1–3. The occurrence of PM1–3, cure rate, calving to conception interval, the hazard of pregnancy, odds for non-pregnancy, and odds for CE were analyzed using SAS software. Results A total of 8876 PM1–3 records were included, 2435 records of PM3 treatments with ceftiofur (27.43 %), and 6441 records of PM1–2 (72.57 %) with no treatment. Cows having PM1 and PM2 became pregnant 14 and 12 days earlier than cows with PM3 (p < 0.001). The PM3 ceftiofur treated cows had a clinical cure of 24.85 % (PM0); 53.63 % had a partially cure; and 18.52 % no cure. Conversely, cows with PM1–2 had a 51.96 %, 20.70 %, and 24.53 % cure rate, respectively (p < 0.001). Cows having complete cure became pregnant 13 and 11 days earlier than cows having partial cure and no cure (p < 0.001). Cows that had PM3 during the first 21 days p. p. had twice the chances of developing CE compared to cows having PM1–2 (41.28 % vs. 24.14 %, p < 0.001). After 21 days p. p., less than 1 % of cows with clinical cure developed CE compared to 63.32 % that developed CE with partial cure, and 38.21 % with no cure (p < 0.001). Conclusion and clinical relevance After ceftiofur treatment, 78 % of cows were cured when measured by disappearance of fetid VD but only 25 % of cows had clinical cure when measured by appearance of a clear VD. The cows that remained with clinical metritis had more chances of having CE after 21 days p. p. and had more days open than cows with clear normal VD.

The effect of days dry and days open on first, second and later lactation production was examined by intra-sire-herd-season regression. Neither variation in days dry nor days open accounted for more than 1% of the within-sire variance in fat test. Variation in preceding days dry accounted for 4.8% of the within-sire variance in milk production in second lactations but only 0.6% of the variance in later lactations. Differences in days open accounted for 4.5, 3.5, and 4.5% of the intra-sire variance in milk production in first, second, and later lactations, respectively. The effects of days dry and days open on fat production were, in all cases, slightly less than the effects on milk production. Heritabilities for both traits were low, indicating that the effects of both days dry and days open on production were largely of an environmental nature. Adjustment of milk yield for the number of days cows are open could lead to more accurate selection of dairy animals.

SUMMARYBreed additive and non-additive effects as well as genetic parameters for calving interval (CI), days open (DO), age at first service (AFS), age at first calving (AFC), number of services per first conception (NSC) and breeding efficiency (BE) were estimated in Ethiopian Boran cattle and their crosses with Holstein Friesian in central Ethiopia. The data analysed were spread over 15 years (1990–2004). The Ethiopian Boran cattle had longer CI and DO, lower BE and delayed AFS and AFC compared with all the crosses. However, there was no significant difference in NSC between the genetic groups. Comparison between the crosses revealed no clear cut superiority of any of the genetic groups except for CI and DO which were shorter for 0·50 and 0·875 crosses compared with the 0·75 crosses. The additive breed differences between Ethiopian Boran and Holstein Friesian for CI, DO, NSC and BE were not significant (P>0·05). These estimates are also associated with large standard errors. The non-significance of the otherwise large difference (40 days for CI for instance) between the two breeds could be a result of a large variation (and hence standard errors) associated with the traits. On the other hand, the estimates for additive direct effects for AFS and AFC were negative and significant (P<0·01). The estimates were −7±2·1 and −7±2·8 months, respectively. The individual heterosis values were not significant (P>0·05) for CI, DO, NSC and BE. However, significant (P<0·01) estimates for AFS and AFC (P<0·05) were recorded. None of the maternal heterotic effects for reproduction traits were significant (P>0·05) except for AFC, for which positive (2·9 months) and significant (P<0·05) estimates were obtained. Heritabilities of CI, DO, AFS, AFC, NSC and BE for crosses were 0·1±0·046, 0·1±0·047, 0·6±0·145, 0·7±0·159, 0·1±0·071 and 0·6±0·156, respectively. Selection coupled with improved herd reproductive management should substantially improve the reproductive performance of the indigenous Ethiopian Boran breed under such production system.

Detection Effect

In this study, it is aimed to investigate the estrus behavior characteristics of cows by observing them comparatively and to reveal especially the sound related features in detail. For this purpose cows were observing during the oestrus time for their vocalization behavior. Oestrus affected by many hormones secreted by the animal during oestrus periods. There are several estrus detection methods, but efficiency differs depending on many factors. Efficient oestrus detection effect reproductive performance, while providing a significant increase in productivity in herd management and eliminating factors that inhibit reproductive performance. This research was investigated between February -May 2017 at Private dairy Farm which is located Mediterranean region of Turkey. At the beginning experiment, cows were selected depending on their characteristics as an example at the beginning of the experiment in order to minimize the experimental error and avoid the effects caused by the differences between the groups. Holstein milking cows which selected similar lactation number (3,1±0,84), body weight (664,69±7,45) and milk yield (25,96±0,49) were used. 150 head cows were synchronized with their estrus using the ovsych protocol and 10 cows were taken observation pen. The barn where the experiment is conducted is a free-stall barn and there are also walking areas for animals. Oestrus behavior of the cows was recorded by the researchers using directly observation methods. During oestrus period vocalizations behavior increased from 12,67±2,11 to 61,46±12,18 calls. During post oestrus period vocalization of cows decreased to 24,00±2,01. There are big variations between the cow vocalization. But cow calling; a statistically significant difference was found between the number of repetitions of sound; repetition was significantly longer in heat cows (p <0.01). Results suggest that more studies are required to draw strong conclusions regarding detailed information about oestrus situation of cow.

Abstract. The aim of the paper was to establish reproductive traits and their heritability during the three successive generations of Holstein-Friesian cattle. Research was conducted on the duration of pregnancy, service period and fertility intensity. In each generation there were 135 first calved cows. Service period and fertility intensity refers to the following calving. Significant differences were established (P < 0.05) regarding duration of pregnancy between I and II generation. Significant (P < 0.05) influence of season on duration of pregnancy and service period was established in I generation (1991), on duration of service period and fertility intensity in II generation (1996) and on duration of pregnancy and service period in III generation (2000). Season effect (summer) was established for all traits of fertility in II generation (P < 0.05). The season (spring) had influence on duration of pregnancy (P < 0.05) and summer had an influence on duration of service period and fertility intensity, and winter effected the duration of service period (P < 0.05) in III generation. Values of heritability coefficients are pretty low for all generations. Considerably greater values for heritability were established for service period and intensity of fertility of cows per generations.

Any genetic improvement in dairy cattle requires information on productive and reproductive performance in the given population. Animals have been selected to improve their productivity in order to increase the profitability to the farmer. As a result, selection of animals is made for higher production and a shortened productive life. The reproductive performance of Friesian cows under intensive and semi-intensive management system in Bangladesh is poor. Animal selection has historically been based on production traits, and not much attention was given to AI recording. Many attempts were taken scatterly to increase productive and reproductive potential of Bangladeshi cattle for different periods with variable achievements. Therefore, in this review article we have addressed the new tools and information that could be used to determine the level of productive and reproductive performance and to evaluate genetic factors using admixture analysis of cows bred by AI sires which affect reproductive traits of crossbred Friesian dairy cows reared in selected areas in Bangladesh.

The main objective of this research was determining the effect of sire of cow, year and season of freshening, lactation number, and their different interactions on 305-day mature equivalent (ME) milk yield of Holstein Friesian cows in the United Arab Emirates (UAE). It also aimed to estimate sire and error variance and heritability of 305-day ME milk yield. The data was collected from AL Salamat Dairy Farm in Al Ain. The average size of the herd was 1000 animals during the experimental period. The Dairy Comp 305 computer program was used for compiling the data. The data under the study covered the years 2004 to 2007. The climatic temperature during the summer (April to September) varied from moderate to very hot. The winter (October to March) had lower temperature and higher relative humidity than the summer. All the effects were fixed except for random sire and residual error term. The overall least-square mean of the 305-day ME milk yield was 11060Å}355 kg/305 days. The data showed a significant effect of sire of cow (p≤0.001), year of freshening (p≤0.001), lactation number (p≤0.01), year x season of freshening (p≤0.01), and year of freshening x lactation number (p≤0.001) on milk yield. However, the effect of season of freshening showed non significant effect. No significant seasonal differences were found in 2004. However, in the year 2005 and 2006, the summer fresheners had significantly higher yield than those of the winter season. The 305-day ME pertaining to summer vs. winter were 11691Å}400 kg vs. 11483Å}410 kg and 11522Å}369 kg vs. 11041Å}374 kg for the year 2005 and 2006, respectively. However, the reverse was true in 2007 with the fresheners during summer that have lower 305-day ME (10286Å}372kg) than those freshening during winter (10672Å}388 kg). The differences among the three lactations were relatively high in 2004 (9837 to 12116 kg), compared to 2005 - 2006 (11267 to 11747 kg) and 2007 (9853 to 11355 kg). The heritability of 305-day ME was 0.31 indicating that a significant response to selection would be achieved through a well-designed progeny testing and cow evaluation program.

Abstract. Forty Thai x Holstein-Friesian (HF) crossbred dairy cows (75 % and 87.5 % HF upgrade level) with calves were used in experiments to investigate restricted suckling (RS) versus bucket rearing (BR) and hand versus machine milking in Thailand. Calves were kept indoors and remained with their dams during the first 4 days and were then allocated to the RS or BS treatment. Milking was done twice daily and RS-calves were allowed to suckle for 15 minutes after milking. All experimental animals were fed according to requirements with concentrate supplements, minerals and water ad lib. This paper reports effects on reproductive performance and weight of cows. Calving to first oestrus interval in cows with RS and BR calves were 72.2 ± 2.5 and 54.7 ± 2.5 (p < 0.001), respectively, and days open 114.2 ± 6.68 and 86.5 ± 6.7 (p < 0.01). Milking method (hand or machine) had no effect on days to first oestrus and days open. Primiparous cows had a longer calving to first oestrus interval than multiparous cows (p < 0.001) (72.3 ± 2.8 vs 54.5 ± 2.3) and a longer days open period (p < 0.01) (114.4 ± 7.4 vs 86.2 ± 6.1). Body weight change of cows during the first 2 months of lactation was not affected by any treatment or systematic factor tested.

Abstract. A total of 2897 lactation records of Holstein Friesian cattle from the fields of Dena Farm in Egypt from 1987 to 1993 were used to study relationships of days open and days dry with milk production. The effect of month and year of calving, sire and cow within sires were also investigated. Month of calving, year of calving, sire and cow within sires significantly influenced milk production. Including DO and DP as a polynomial of second degree of production were significant. The partial linear and quadratic regression coefficients of 305 day milk yield on DO and DP were significant, being 7.59 ± 0.40 kg/d and −0.37 ± 0.00 kg/d2, respectively for DO and −9.37 ± 0.54 kg/d and 0.02 ± 0.00 kg/d2, respectively for DP. Therefore, reduction of DO and DP are a desirable goal of dairymen. Heritability (h2) estimates for 305 day milk yield, DO, DP were 0.13 ± 0.05, 0.00 and 0.00, respectively. Adjustment of lactation milk yield for DO will not involve genetic influence on milk yield.
