Abstract:
Optimising heifer growth rates is an essential component of dairy replacement management in order to ensure sustainable heifer replacement stocks. Continuous evaluation of the growth pattern of heifers in a herd may be used to identify particular effects of nutritional management and the environment. Body weight is considered the most useful indicator of a heifer’s growth rate, both in practice and experiment work, along with body measurements reflecting the skeletal growth of heifer. The aims of this research are to investigate: 1) body trait : age relationships, 2) ratio of body measurements to body weight, and 3) to predict body weight based on body measurements of Holstein heifers in Indonesia.

Abstract:
Abstract Beef cattle longevity can be tied to reproductive performance. Developing heifers that will thrive in their environment, under specific management systems, is crucial for today’s producers. Management decisions influencing heifer fertility are numerous; however, the most commonly discussed and studied revolves around nutrition. The objectives of this presentation are to review our understanding of the influence of nutrition on beef heifer fertility and identify potential mechanisms which may improve heifer fertility and beef producer profitability. Also, we will identify management decisions that may impact body weight gain or efficiency of weight gain, thus impacting fertility. Management strategies delaying heifer growth patterns pre- or post-weaning have been reported to alter heifer reproductive performance. Additionally, developing heifers on native range compared to in the dry lot or confinement settings may alter growth rates/patterns, thus affecting the heifer’s ability to become pregnant, or maintain that pregnancy. Supplementing heifers with specific nutrient profiles has also been reported to improve pregnancy rates compared with non-supplemented or control animals. Previously, it was believed heifers are born with a finite number of follicles within their ovaries, and the depletion of the ovarian reserve occurs at a constant rate. Recent research has challenged this, reporting heifers developed on a stair-step growth program had an increased number of primordial follicles compared to constant gain developed heifers. Additionally, development system (native range vs. dry lot) appears to impact ovarian function. Continued research increasing our understanding of mechanisms involved in improving heifer fertility are warranted. These efforts will aid in identifying management strategies that will optimize animal reproductive performance.

Abstract:
Abstract Alternative methods to antibiotics/chemical usage in cattle production has been of interest in recent years and essential oils/spices have been promoted to fill this niche. The purpose of this research was to evaluate effect of feeding spices on heifer gains and as control method for ticks. Eight bromegrass pastures were stocked (March to November) with four heifers per pasture to compare control mineral (CON) to mineral containing spices (SPICE; garlic + proprietary blend of 4 spices). Mineral (113.4 g/hd/d) was blended in dried distillers grains (DDGs) and total blend was supplemented daily at 0.5% of BW. Heifers were weighed on two consecutive days at the start and end of the study and every 28 d. Weekly (1st 10 weeks), ticks were counted and removed from every heifer. Gains evaluated using MIXED (SAS 9.4) as completed randomized design with subsampling where pasture was experimental unit and heifer within pasture as subsample. Ticks/heifer was evaluated similarly using GLIMMIX with binomial distribution. Average daily gain was increased by 0.7 kg/d with the SPICE mineral (P = 0.04) and heifers on SPICE gained 15 kg more over the entire grazing period (P = 0.04) than heifers on CON. The gain advantage for SPICE was observed within the first 28 d (P = 0.05). Overall, these pastures had a low tick population (137 total ticks collected). Even so, there was a tendency (P = 0.09) for a treatment x week interaction, where in weeks 2 and 3, SPICE heifers tended (P = 0.12) to have more ticks/heifer than CON heifers, yet at weeks 8 and 10 SPICE heifers tended (P = 0.07) to have less ticks/heifer than CON. SPICE in a mineral blended with DDGs increase heifer gains and appear, after a minimum of 4 weeks of consumption, to show some repellent effects to ticks.

Abstract:
The weight of 2659 Friesian heifers was measured electronically on 41 farms in north-eastern New South Wales during autumn 1992. The 41 producers involved were surveyed on their heifer management practices. The relationship between liveweight and age was determined from these measurements. This provided a base line against which improvement in heifer weight for age could be measured subsequent to a planned extension program. In 1992, 2 management practices were found to be associated with significantly higher weights for age. These were feeding more than 1 kg of concentrate to heifers prior to weaning and grazing heifers on fertilised pasture between weaning and 12 months of age. An extension program promoting improved heifer management was conducted, using adult learning principles, from 1992 until 1995. Nineteen of the 41 farms were revisited in winter 1997 when the heifers were again measured and management practices surveyed. Heifer weight for age had increased by a small but significant amount between 1992 and 1997. Management changes which occurred between 1992 and 1997 were: increased vaccination rates; decreased use of antibiotic injections for treating calf illnesses; increase in feeding over 1 kg of concentrate per day to preweaned heifers; and increased use of silage to feed weaned heifers. There was also a decreased percentage of producers who considered calf diseases to be a problem. Between 1992 and 1995, 14 farmers began monitoring their heifers regularly, either by measuring weight electronically or by using a weigh tape.

Abstract:
Abstract The objective was to determine the effects of beef heifer management system on growth performance and fescue toxicity. Fall-born Angus × Simmental heifers (n = 199; BW = 229 ± 24 kg] were stratified by BW into 12 groups and groups were randomly assigned to 1 of 4 treatments: dry-lot developed (DL); grazing endophyte-infected fescue supplemented with 2.3 kg dried distiller’s grains with solubles (DDGS) and soybean hulls per heifer daily (GF); grazing endophyte-infected fescue supplemented with 4.5 kg DDGS and soybean hulls per heifer daily from the midpoint of experimental period until breeding (GFLate); and grazing novel endophyte-infected fescue (GNF). The DL heifers were ad-lib fed a diet consisting of 70% hay and 30% DDGS. Experiment began in May and ended at time of AI. There was a treatment × time interaction (P < 0.01) for BW, BCS, HCS, and RR. There were no BW differences (P = 0.99) at trial initiation; however, on d 28, 56, 84, 112, and 148, DL heifers had greatest (P < 0.01) BW, with GF intermediate, and GFLate and GNF having the lightest BW. There were no BCS differences (P = 0.42) at trial initiation; however, on d 56 and 84, DL heifers had greatest (P < 0.01) BCS, with GF intermediate, and GFLate and GNF the lowest. On d 148, DL heifers had greater (P < 0.01) BCS than GF, GFLate, and GNF which were not different from each other. There were no HCS differences (P = 0.51) at trial initiation; however, on d 28, 84,112, and 148, GFLate had the greatest (P ≤ 0.03) HCS. For RR, DL had the greatest (P < 0.01) RR on d 28; on d 56, GNF had greatest (P < 0.01) RR; and at d 112, GFLate had greatest (P < 0.01) and DL least (P < 0.01) RR. Heifer management system impacted symptoms of fescue toxicity and heifers developed in a dry lot had the greatest BW and BCS.

Abstract:
In a national survey of US dairy operations, 1685 dairy operations reported 47057 new dairy heifers (either births or acquisitions) and 4427 deaths (9·4%) of preweaned dairy heifer calves over a 3 month period. Stepwise logistic regression was used to identify management practices associated with high mortality among preweaned heifers in dairy operations where at least three dairy heifer calves were born alive or moved on to the operation. Analysis was done twice: once by separating all operations by size into high or low mortality; again using only operations with <2 and >10% mortality to eliminate dairy operations with intermediate levels of mortality from the comparisons. Results were similar. Dairy operations in the West were more likely to fall in the high mortality category than dairy operations in the rest of the country. In addition, the following dairy operation characteristics were associated with high death levels in both models: rolling herd average milk production <7710 kg, preweaned heifers placed in groups of seven or more, a male having primary responsibility for the care and feeding of preweaned heifers, calves not receiving hay or other roughages until >20 d old, calves fed on mastitic or antibiotic milk after colostrum and calves not given whole milk after colostrum.

Abstract:
Management factors in 36 Pacific Northwest dairy herds were evaluated for their association with the prevalence of Shiga toxin-positive Escherichia coli O157 (E. coli O157) in dairy cattle. The within-herd prevalence of E. coli O157 was estimated by bacteriological culture of fecal pat samples, collected monthly for 6 months (approximately 60 per visit), from heifer cattle. During the first visit to each farm, a management questionnaire was administered that covered a broad range of animal husbandry practices. On each subsequent visit, a brief questionnaire was administered to detect changes in management practices. A significantly higher prevalence of E. coli O157 was noted in herds that fed com silage to heifers compared to herds that did not feed com silage. More tentative associations of E. coli O157 prevalence were observed for weaning method, protein level of calf starter, feeding of ionophores in heifer rations, feeding of grain screens to heifers, and feeding of animal by-products to cows.

Abstract:
AbstractThe aims of the research reported here were to identify potential risk factors associated with the presence of Staphylococcus aureus intramammary infection (IMI) in pre partum dairy heifers on 17 dairy farms from three provinces of Argentina and to characterize, at molecular level, isolates from those heifers and lactating cows from two selected herds. A total of 1474 heifers and 4878 lactating cows were studied. The prevalence of Staphylococcus aureus IMI in the heifers, heifers at quarter level and lactating cow mammary quarters was 14.41, 4.82, and 14.65%, respectively. Univariate analysis showed the key variables associated with S. aureus IMI presence in the heifers were: S. aureus IMI prevalence in cows of the lactating herd, the time calves stayed with their dam after birth, the calf rearing system, the place of rearing (own farm or other dairy farm) and fly control on the farm. None of the variables included in the multivariable analysis was associated with the presence of S. aureus IMI in the pre partum heifers, probably due to low variability among management practices used by the farms for rearing the heifer calves. At the molecular level, S. aureus isolates were grouped into three main PFGE clusters and several genotypes within the clusters. Isolates from mammary secretion of pre partum heifers and milk of lactating cows comprised different PFGE clusters in both herds, although two exceptions occurred. The absence of gene fnbpB, which codifies for a virulence factor protein involved in cell invasion by S. aureus, was significantly more frequent in pre partum heifer secretion isolates than in isolates from lactating cow milk. These results suggest that, under these management conditions, isolates from mammary secretions of pre partum heifers do not originate from the milk of lactating cows, but rather other sources to which the heifer is exposed.

Abstract:
SUMMARYDespite practical information and applied results from numerous experimental studies and/or field observations, there is a persistent gap between scientific recommendations and on-farm reality. There are numerous published reports on the impact of dairy heifer herd management conditions on short-term, medium-term and long-term performances, but few studies on actual dairy heifer herd management practices – particularly in France. In an attempt to address this shortfall, a survey was conducted in 2010 on 449 herds located in the second largest dairy production region, the Pays de la Loire region (Western France). Economic-related aspects of heifer farming were not addressed. The essentially qualitative survey information was collected by 107 independent agricultural technologists. A quantitative analysis based on a small set of the most representative key production criteria was also conducted on a representative sub-sample of 286 herds. Mean herd size, at 46·6 cows per farm, and milk production, at 7953 kg milk/cow/lactation, were close to French national averages (47·3 cows per farm and 8109 kg milk/cow/lactation). The survey covered nine core themes and confirmed an all-round lack of precise monitoring on animal growth, as reported in earlier studies performed outside France. Most of the farmers surveyed considered animal weight a useful indicator for estimating growth performance. However, very few actually weighed their animals, despite the fact that 0·80 of the farmers surveyed aimed to calve their heifers before 30 months of age, with 0·55 of them setting a minimum calving weight target of at least 610 kg. Mean calf age at weaning was 2·9 months, but in practice this was >3·5 months in 0·31 of cases. Although farmers differ on certain practices, common core foci emerged: weight or age targets for pre-determined growth and development stages (at weaning or at service), recycling non-marketable milk for feeding young calves, essentially visual oestrus detection methods, and others. Based on the farmers’ declarations, the estimated time spent rearing a heifer from birth to calving ranges from 12 to 15 h per animal, with most farmers spending an estimated 0–2 h/day rearing their heifers. While almost two-thirds of farmers stated that rearing heifers was a necessity, 0·36 of this survey population claimed they enjoyed the work, whereas 0·02 of the farmers felt the work was purely a chore. Mirroring the conclusions from other countries, dairy heifer herd performances could be improved through better animal monitoring and management.

Abstract:
Two surveys evaluated heifer management practices in dairy herds and custom grower operations. The NC-119 Heifer Management Survey conducted through the North Central Regional Research Project 119 included 226 Holstein and 67 Jersey herds from MN, MO, PA, VA, and WA. Mean rolling herd average for milk was 8,838 and 6,251 kg for Holstein and Jersey herds, respectively. Calf mortality rates from birth to first calving were 15.3 % for Holsteins and 15.8% for Jerseys. High producing herds had more aggressive, preventive health programs, hand-fed colostrum to newborn calves, and used prepartum groups and separate postpartum groups for first calf heifers. Practices associated with low calf mortality included using maternity pens in barns separate from the dairy herd as a calving facility and vaccination for brucellosis, an indicator of the level of overall management. Larger herds weaned calves earlier, placed more importance on heifer size as a criterion for first breeding, and used prepartum groups and separate postpartum groups for first calf heifers States differed in calving facility and calf housing choices. Calf mortality rates were similar among states. The Virginia Custom Dairy Heifer Rearing Survey included 24 growers. Average herd size was 194 head. Seven growers contracted with dairy producers, nine purchased, raised, and resold heifers, and eight did both. Survey results indicated a need for increased emphasis in several management areas. Only two contract growers had written contracts. Fifty-eight percent never monitored growth and 42% did not have forages tested or rations balanced. Fifty-seven percent used AI.<br>Master of Science

Abstract:
A microcomputer simulation was developed as a tool for analyzing the dairy replacement enterprise. The simulation was constructed using a spreadsheet, and equations were developed using stepwise regression procedures. The simulation predicted BW, DMI, and fixed and variable costs for each week of a heifer's life from birth to calving. After calving, milk yield, feed costs, and fixed costs were predicted for first lactation. Variation was estimated for each predicted variable, thus enabling normal distribution of predicted values. The simulation was used to analyze profitability of various growth rate scenarios and marginal costs associated with changing feed costs, heat detection efficiency, death loss, and abortion rate. For the growth analysis, six scenarios were evaluated: 1) normal growth from 5 wk to calving, 2) Accelerated growth from 5 wk to calving, 3) slow growth from 5 wk to calving, 4) normal Growth from 5 wk to 14 mo and accelerated growth from 14 mo to calving, 5) accelerated growth from 5 wk to 14 mo and control growth from 14 mo to calving, and 6) slow growth from 5 wk to 14 mo and accelerated growth from 14 mo to calving. Average daily gain from birth to calving was 0.78, 0.90, 0.62, 0.78,0.75, and 0.80 kg/d, and age at calving was 25.1, 23.1, 27.4, 23.1, 23.0, and 23.1 mo,respectively. Total rearing cost from birth to calving was 1246, 1220, 1275, 1148, 1148, and 1138 $/heifer, and net profit through first lactation was 399, 407, 319, 441, 432, and 463 $/heifer, respectively. Results suggest modest growth rates from birth to calving (0.75 to 0.80 kg/d) with reduced first calving age <24 mo) is most desirable, and delayed calving (>24 mo) is costly and merits higher growth rates with earlier breeding. Increasing feed costs, death loss at birth through weaning, or abortion rate one percentage point increased rearing costs 7.33, 2.40, and 9.10 $/heifer. Improving heat detection efficiency one percentage point reduced rearing costs $2.80/heifer. For the heat detection analysis, the relationship between age at first calving and total rearing costs was -584.38 + 73.49 x calving age in mo (R-squared = 0.97), for ages at first calving from 24.4 to 26.6 mo. Results of this research agree with field observations that managers should strive for early calving (<24 mo) and modest growth rates (0.75 to 0.80 kg/d) to maximize profitability of the replacement enterprise. In addition, death loss, abortion rate, and heat detection efficiency are variables that a manager must control to minimize heifer rearing costs.<br>Ph. D.

Abstract:
Heifers should represent the greatest genetic potential within a dairy herd. To maximize this potential, heifers must be inseminated to proven sires, a practice requiring management changes on many dairies. Holstein heifers (n=115) were allotted to one of three groups to compare alternatives to daily estrous detection that may facilitate the management of a program of artificial insemination for heifers. Group 1 heifers (Controls) received no treatment but were observed twice daily for signs of estrus. Group 2 heifers (2X-PGF) were synchronized with two injections of prostaglandin F2 alpha given 11 days apart and observed for estrus. Group 3 heifers (MGA+PGF) were synchronized with 9 days of melengestrol acetate feeding and an injection of prostaglandin F2 alpha 14 days after the last feeding and observed for estrus. Comparisons were made on the effectiveness of each treatment in estrous response and pregnancy rates and on the management requirements and economics associated with each program. Estrous response was significantly higher for the 2X-PGF group, while synchronized pregnancy and first-service conception rates did not differ. On an annual basis, the MGA+PGF group was calculated to require three-quarters of the labor input as compared to the 2X-PGF group and less than a fifth of the labor required for the Control group. A program of daily estrous detection was calculated to have an economic advantage over synchronization the frequency estrous synchronization programs was scheduled four times per year. was increased to six times per when When year, synchronization had a slight economic advantage over daily estrous detection when animal numbers were low and labor costs were high. The economic advantage of daily estrous detection is reduced when synchronization is performed more frequently throughout the year.
