Fertility Traits

Fertility traits have been included within breed selection programmes for the Norwegian Red (NR) dairy cow population in Norway for over thirty years. As a consequence, a 60 day non-return rate to first artificial insemination (AI) of 72.5% was recently calculated for NR cows in Norway (Garmo et al., 2008). In view of this long term breeding programme, and current fertility performance within Norway, there is considerable interest in the NR breed as a means of overcoming the high levels of infertility that currently exist within the Holstein-Friesian (HF) breed. However, farming systems within Norway are very different from those within the UK, with herd sizes in particular being much smaller. Thus an experiment was established on 19 commercial dairy farms to compare the fertility performance of cows of the NR and HF breeds.

The economic pressures on the dairy industry may force more farmers to consider reducing the amount of concentrates fed to cows in order to keep costs down. We have been testing whether the long-term performance of daughters of sires progeny tested in high concentrate systems maintain their advantage over cows of average genetic merit when managed in a lower input feeding system. This paper extends the scope of our initial report (Chalmers et al., 1997) and includes data on reproductive performance.Data were from Holstein-Friesian cows managed at the Langhill Dairy Cattle Research Centre. Sires of the Selection (S) line are among the highest available in the UK for predicted transmitting abilities of weight of fat plus protein (PTA F+P). Sires of Control (C) line cows are about UK average for PTA F+P.

Effect Of Feeding

Major changes have been occurring over the last 20 years in the UK dairy industry, with improvements in cow genetics and nutritional management resulting in a doubling of average milk yields to 6,750 litres/cow/year by 2004 (DEFRA, 2005). The same period has resulted in a decline of dairy cow fertility parameters with recent studies having identified a 1% fall in conception rates per annum (Royal et al., 2000). The role of organic forms of trace minerals has been examined in ruminant diets with particular regard to their role in immune function (Spears, 2000). The aim of the study was to examine the effect of feeding an organic source of zinc (Bioplex Zinc™, Alltech Inc. USA) and selenium yeast (Sel-Plex™, Alltech Inc. USA) to high yielding Holstein dairy cows on production and reproductive performance.

Poor fertility is a major problem on dairy farms. On-farm studies indicate than pregnancy rates to first service have declined from approximately 55% between 1975 and 1982 to 39% between 1995 and 1998 (Royal et al., 2000), illustrating a decline of approximately 1% per year during this period. The cause is multifactorial and influenced by many factors including genetics, management and nutrition. Previous studies have reported improved fertility through nutritional modification in early lactation (Gong et al., 2002). The aim of this study was to evaluate the effect of nutritional strategy in early lactation on reproductive performance.

Lameness causes significant economic losses and serious welfare problems in dairy cows. Surveys carried out in the UK since 1960 have produced different results. In a recent survey (1989/1991) the annual incidence of lameness was put at 54.6 limb cases per 100 cows. The objective of the present survey was to measure the incidence of lameness, and type of lesions involved, in a group of typical UK herds using the Dairy Information System (DAISY).A survey was carried out using computer based dairy cow records from 17 DAISY sites (veterinary practices and farms) in southern England. Lameness records from over 150 herds were examined for lameness cases (treated by the vet or farmer) recorded between July 1995 and June 1996. Data reliability was checked via personal contacts with veterinary surgeons involved with these herds. Data for the survey were finally derived from 50 Holstein/Friesian herds (average herd size 150 cows).

AbstractAfter decades of farm specialization, re-integrating crop and livestock farming systems is being reconsidered as a key step toward sustainable agriculture. The relative profitability of Maine farms integrating crops and livestock is compared to non-integrated or conventional farms. Crop and livestock integration in Maine occurs through either diversified on-farm integration or, more commonly, through coupled interactions between specialized crop and livestock producers. Potato and dairy systems coupled for only 2 years (short-term) had greater profitability compared to conventional systems. Profitability increased in the short term in two ways. First, potato farms grew more of their primary cash crop. Secondly, dairy farms expanded cow numbers, increasing profitability assuming increasing returns to scale. Coupled systems integrated for more than 10 years (long-term) had more favorable profitability than short-term couplers since greater manure-nutrient credits were taken for potatoes and silage corn. The advantages of potato–dairy integration were even greater if potato yields increased in the long term, as suggested by long-term rotation plot studies in Maine. Even if coupling is more profitable than non-integrated systems, it requires that farms be in close proximity and for farmers to have adequate working relationships and management skills. Despite these challenges to re-integrating crops and livestock, short- and long-term economic benefits may encourage farmers in appropriate areas to consider coupling with other producers.

Dry period management of the dairy cow focuses on maximising milk production during the subsequent lactation but may include procedures that negatively affect dry cow health and welfare. A survey of dairy farmers in the UK was conducted to investigate dry cow management procedures. The questionnaire was completed by 148 farmers. Most farms (84 per cent) kept dry cows in dynamic social groups. The median length of the dry period was 56 days, and 83 per cent of farms stopped milking abruptly, regardless of milk production level at dry-off. Twenty-seven per cent of cows from respondent farms produced more than 20 kg of milk per day at dry-off. The majority of farms (78 per cent) used antibiotic dry cow intramammary tubes at dry-off, in combination with internal or external teat sealants. Procedures that were commonly practised and potentially stressful for dry cows included abrupt cessation of milking of high yielding cows and frequent changes in diet and social environment.

The drive for improved carcass quality has encouraged greater use of continental cross suckler dams (MLC,1993), producing three-quarterbred continental progeny. Little information is available on the performance of these types of suckler cow under hill conditions in the UK, but significant genotype by environment interractions have been measured elsewhere (Morris et al, 1993). As a finished animal, the Piemontese cross has shown significant advantages in killing-out proportion and yield of saleable meat (Davies et al, 1992), and some improvements in eating quality (Fisher et al, 1992).The objective of this experiment was to assess the output and reproductive performance of Piemontese cross Holstein/Friesian (PxH/F) and Simmental cross Holstein/Friesian (SxH/F) heifers in an autumn calving suckler herd.

Low Incidence

Norway has adopted a multi-trait selection programme within its Norwegian Red (NR) dairy cow population for over thirty years, in contrast to breeding programmes with the Holstein-Friesian (HF) breed, which have, until recently, focused primarily on milk production. As a result, evidence from Norway suggests a dairy cow population with high levels of fertility and a relatively low incidence of mastitis. Consequently, there is considerable international interest in the NR breed as a means of overcoming some of the fertility, health and longevity problems that currently exist within the HF breed. To examine the potential of the NR breed, an experiment was established on 19 commercial dairy farms to compare the production, fertility and longevity of animals of the NR and HF breed across a range of production systems.

Background and Aim: Milk yield (MY) is one of the main factors that affect the economic profitability of dairy farms. Thus, increasing the MY per animal and decreasing the feed cost can lead to economic gains, so the objective of this study was to evaluate the effect of dry period length (DPL), days open (DO), and days in milk (DIM) on the productivity and profitability of dairy cow farms. Materials and Methods: Data used in this study were taken from 3095 lactation records of Friesian dairy cows of private and governmental sectors. The data were classified into 4 DPL categories: DPL1 <45 days; DPL2 45-60 days; DPL3 61-75 days, and DPL4 >75 days, 3 DO categories: DO1 ≤90 days; DO2 91-110 days and DO3 >111 days, and 8 DIM categories: DIM1 180-210 days; DIM2 211-240 days; DIM3 241-270 days; DIM4 271-300 days; DIM5 301-330 days; DIM6 331-360 days; DIM7 361-447 days; and DIM8 >447 days. Results: The average net profit (NP) was significantly different (p<0.05) among different categories of DPL, DO, and DIM in both production sectors, where high estimates of NP were calculated for DPL3 (30667.3 EGP), and it was the lowest for DPL1 (19690.6 EGP). DO2 had the highest NP (30754.1 EGP), while DO3 had the lowest NP (24875.5 EGP). DIM3 had the highest NP (29569.3 EGP), while DIM8 had the lowest NP (19528.4 EGP). Conclusion: Finally, we can conclude that DPL 61-75 days, DO 91-110 days, and DIM 241-270 days had the highest level of total MY, total return, and NP. Private dairy cow farms achieve a higher level of NP than governmental ones under subtropical Egyptian conditions.
