Intensive dairy farming systems from Holland and Brazil : SWOT analyse comparison

Intensive systems of milk production in Brazil and Holland are compared by SWOT analysis. Twenty-one farms, 10 in Wageningen, central region of Holland, and 11 in Castro, central-eastern region of the state of Paraná, Brazil, were sampled. Data were retrieved from semi-structured interviews with the owners or people responsible for dairy activities, using a questionnaire guide and a digital recorder. After results were analysed, a table was elaborated representing the strengths, weaknesses, opportunities and risks for each country. Dairy farms in Holland were uniform, or rather, small and medium-sized farms with high production. It has also been observed that Dutch farms have several problems due to high intensification, for example, hoof diseases with great economic loss. In the case of Brazilian dairy farms, several types of systems and degrees were detected. Brazilian production in the region analysed features a higher quantity than that in Holland, with less intensity when compared to that on Dutch farms.


Introduction
The characterization of dairy farming systems is important to identify the main impairments in the production sector and in the implementation of projects within regional development (Assis et al., 2005;Godinho, & Carvalho, 2013).Comparing the characteristics of Brazilian dairy farms with wellstructured production systems, such as those in Holland, contributes towards the development of the sector in Brazil.
Dairy farming systems in Holland are characterized as a family production, involving high technology (Thomassen, van Calker, Smits, Iepema, & de Boer, 2008).The cost of labor is relatively high and the use of modern machines such as cleaning robots for stables, robotic milking, tractors, seeders and harvesters to optimize system productivity are more viable (Wade, van Asseldonk, Berentsen, Ouweltjes, & Hogeveen, 2004).
According to a survey conducted by Wageningen University, Dutch dairy farms are characterized as intensive.As a rule, Dutch farms average 78 lactating animals in the herd, producing more than 8,000 kg of milk per cow -1 year -1 in small 51-hectare farms where 38 hectares are reserved for the production of grass silage and 8 ha for maize silage.The animals are housed in a free-stall system where the animals remain grouped, but with free access to bed and individual feeders.
On the other hand, there is a great difference between extensive and intensive dairy farm systems in the state of Paraná (Lopes Junior et al., 2012;Silva, Moraes, Hack, & Faccio, 2008).Extensive production systems are characterized by the use of non-selected animals, with an average production of less than 4000 kg cow -1 year -1 , low usage of concentrated and preserved forage for the dry season and manual milking (De La Ossa, Lana, Gutierrez, & Márcio, 2013).
In intensive systems, specialized animals are housed in a free-stall system, fed on high quality forages, such as alfalfa and corn silage, and animals are milked in automatic milking parlors (Lopes, Santos, & Carvalho, 2012).These specialized farms producing over 6000 cow -1 year -1 on average are mainly concentrated in the middle region of the central-eastern section of the state of Paraná, in the municipalities of Castro, Arapoti and Carambeí (Paula, Martins, & Silva, 2009).
The town of Castro in the state of Paraná, Brazil, with strong Dutch influence, has a potential to produce winter grasses as in Holland.The animals bred in the region are from the same stock as those used by Dutch farmers, surmising that the dairy production of the Brazilian town of Castro would equal or exceeds Dutch milk production (Fagan, Jobim, Júnior, Silva, & Santos, 2010).So that such a comparison may be undertaken, specific tools are required to assess the farm qualities of each region.
Strengths, Weaknesses, Opportunities and Threats (SWOT) analysis is a strategic planning tool used to provide information on different productive sectors.So that the intrinsic and extrinsic aspects of Dutch and Brazilian farms could be identified, the SWOT matrix organizes the internal environment of the farm with regard to its strengths and weaknesses, as well as its external environment property with regard to opportunities and risks.In fact, SWOT analysis has already been applied as a tool to assess the impact of strategic planning in a small company dedicated to milk production (Marion & Segatti, 2006).
Current study determines the main characteristics of intensive dairy production system in the state of Paraná, Brazil, represented by Castro and the neighboring region, and that of Holland, represented by Wageningen and its surrounding region.More specifically, current research investigates the strengths and weaknesses detected in both systems, coupled to the external factors that exert their influence in Brazil and in Holland.

Material and methods
Current study comprised the comparative evaluation of Dutch and Brazilian intensive dairy farming systems represented by Wageningen and Castro, respectively located in the central and southern region of each country.
For data collection, 21 farm owners were interviewed, 10 in Wageningen, between June andJuly, 2013, and11 in Castro, between September andOctober, 2013.The selection of the farms was discussed with professionals from the region and dairy milk experts representing the intensive dairy farming systems of each region.
Information was based on semi-structured interviews with the owners or those responsible for the activities, using a questionnaire guide and a digital voice recorder (Foddy, 1994).
So that the farms could be properly characterized, data were collected on production index by several questions on the number of persons employed; total area of the farm; total milk production; number of lactating cows; cow production day -1 ; fat and protein percentage; Somatic Cell Count (SCC); price paid for milk; concentrate efficiency; replacement rate; age at first calving and duration of the dry period; data on the general characteristics of the farms were collected by qualitative questions on rearing system; feeding system; forage used; major problems and criteria for animal selection.
Data from the answers of the questionnaires were tabulated (Excel 2007 and SPSS Statistic 19) and analyzed, based on frequency distribution of calculations to characterize the systems of the two countries.Dutch and Brazilian production systems were compared by SWOT analysis (Marion & Segatti, 2006).
The strengths, weaknesses, opportunities and threats of the farms from each country were analyzed by data collected from the interviews and from a review of the literature.

Results and discussion
The Boxes 1 and 2 show the Strengths, Weakness, Opportunities and Threats from the SWOT analyses of dairy farms interviewed from Wageningen, Holland, and Castro, Brazil.The dairy farms in Holland are small and medium-sized, with few employees, since production has a familial feature.The number of workers on the farms surveyed did not exceed two since the owners themselves administered the farm (Table 1).The cost of labour in Europe is relatively high, making the production system inefficient when several people are hired (Ciolos, 2010).Current study showed that Dutch farms averaged 54 ha (Table 1), similar to rates reported by Wageningen University in 2012.According to the European Commission -Agriculture and Rural Development (Ciolos, 2010), farms are entitled to receive a government subsidy according to their size, provided they adopt food safety standards and animal welfare.The subsidy paid by the government not only enhances a more competitive production but also encourages and maintains the population in agricultural activities.In fact, farmers provide an ecological service by taking care of the forest and water reserves.It is very common to find several small farmers throughout Holland demanding the grant.
Besides high milk production rates, high amounts of fat (4.4%) and protein (3.5%) in the milk produced on Dutch farms are reported (Table 1) The protein content is similar to rates (3.5%) recorded by De Marchi, Bittante, Dal Zotto, Dalvit, and Cassandro (2008), although fat contents reported by the authors of the above study were lower than those observed in current one.The difference is due to the fact that the concentration in milk fat varies more easily than protein, mainly influenced by the diet of animals.Animals fed on higher availability of effective fiber in the diet have a higher formation of acetic acid in the rumen, which is the precursor of milk fat.
Somatic cell count (SCC) is indicative of the health of the mammary gland and therefore herd management.An increase in SCC may be caused by various factors such as udder inflammation, mastitis, metabolic diseases, such as acidosis, ketosis and laminitis, which increase the number of antibodies in the blood conveyed into the milk.SCC is also due to the animal´s intrinsic factors.Older cows have an increased desquamation of epithelial cells resulting in an increased amount of expressed somatic cells in milk.In 2011, the United States Department of Agriculture established as requirements for the milk quality and health program that the amount of SCC in tanks must not be higher than 400,000 cells mL -1 (USDA, 2011).Since an average of 138,400 cells mL -1 (Table 1) was reported for farms surveyed in Holland, the milk produced proved to be of very high quality and safety for human consumption.
Milk production is dependent on the herds´ reproductive features since there is an inverse proportion between milk production and reproduction.Table 1 shows the reproductive parameters analyzed: the average age of heifers at first calving (23 months) and the duration of the dry period of the animals (5.5 weeks).The age at first calving is in part influenced by genetics and by feeding management during rearing since the animals may be first mated after reaching 360 kg live weight (Silva et al., 1998).Heifer diets which meet these demands gain weight faster and consequently reach sexual maturity earlier.With regards to the dry period, two factors affect its duration: the lactation cycle and the fecundation of cows.In Holland, the milk production cycle is 305 days, with a quick return to oestrus and insemination 42 days after calving.A fast return increases the efficiency and economic return of milk production.However, it is important to observe that cows that produce a lot of milk have greater difficulties to return to the reproductive cycle due to the high nutrient demand required for lactation.The produ semi-feedlot w with restricted farmers (Figu Castro was sli or rather, 6.7% levels accepte 2011) (  (Barton,200 as been incre ease in bac Clark, 2003).farmers increased their milk production.However, in Holland, the increase of production by an increase in the size of the property is complex and expensive.Consequently, farmers tended to invest in the intensification of animal husbandry systems.In recent years there has been a reduction in the production of grazing animals in Holland.Dutch farmers rate grazing low since this productive strategy would result in lower milk production when compared to more intensive systems (Reijs et al., 2013).However, when the concentrate efficiency between Holland and Brazil is compared, one may conclude that grasses grown in Holland have a higher quality and supply a significant portion of animal requirements, because they have similar milk production (Table 1).
As a result of the intensification of dairy farming systems, the number of hoof diseases increased.An alternative to problems caused by the free-stall system would be the use of restricted pasture during the spring since it minimizes the load of microorganisms in the environment by few contacts with the faeces.Since the animals are placed on a softer floor, the pressure on the feet is lessened and hoof wear is minimized.Reducing the hoof issues means a decrease in antibiotics.Furthermore, the use of restricted grazing may increase the price paid for milk.The price of a milk litter paid to Dutch producers at the time the interviews took place was approximately R$ 1.09, which was lower than the amount received by Brazilian producers (Table 1).However, Friesland Campina, the largest Dutch dairy industry since 2011, in its line of organic products, increased the bonus of € 0.05 to € 0.50 for every 100 kg of milk produced on farms that apply restricted grazing for at least 6 hours during 120 days.The bonus system is greatly attractive to producers because, according to the company, this alternative increases the producers´ income from € 300.00 to € 3,000.00 on farms that produce approximately 600,000 kg of milk per year.

Brazilian farms
The main criterion for animal selection was milk production, followed by udder conformation, percentage of solids and leg conformation (Figure 4).It should be underscored that the production of milk per cow on the farms was high, since the Holstein breed is a specialized breed for milk production.In contrast, fat and protein production is lower when compared with the Jersey strain.Fat and protein percentage is taken into consideration in milk prices.The increased production of solid milk in Brazil is possible since the same strains are used on Brazilian and Dutch farms.However, Brazil still needs to incorporate a breeding program for the Holstein strain to select cows for the high production of solid milk.Due to the high incidence of hoof diseases, the main criterion for animal selection has been the conformation of legs (Figure 4).Animals which have a good conformation and structure of legs and knees have a less chance to develop lameness.The conformation of legs possesses a high negative correlation with milk production, since in the future the cows decrease their milk production potential (Klassen, Monardes, Jairath, Cue, & Hayes, 1992).

Brazilian farms
The animal diets on Brazilian farms are highly dependent on corn production.All interviewed farm owners use corn silage and ground corn in concentrates as a source of forage.The concentrate´s efficiency is lower when compared to that used in Holland (Table 1).The interviewed milk producers in Castro required 29 kg of concentrate to produce 100 kg of milk.Droughts during the last years in the USA caused a steep rise in the price of corn.Due to the high demand for this type of food for milk productivity in the Castro region, it is closely linked to the price of corn.High fluctuating prices throughout the year is a risk factor to farmers, since drastic changes in price would result in a significant increase in animal feed costs.
Although the SCC of cows on Castro farms are within acceptable levels by European standards, many farmers answered that mastitis was the main problem (Figure 4).There are basically two types of mastitis: clinical mastitis, which is visible to the black strip plate test, and subclinical mastitis, where no clumping exists, but has an increase in somatic cells.Subclinical mastitis causes an increase in the SCC tank since cows that have lumps are separated from the herd and treated with antibiotics

Conclusion
There is no better or worse production system.However, after analyzing the characteristics of the two production systems in the Wagenigen and Castro regions, there are practices that may be used by both to increase the production and efficiency of each dairy farming system.Holland has experienced several problems due to high intensification of milk production.The practices used in more extensive systems such as semi-feedlot may reduce the problems that affect these farms especially with regard to the health of hooves.On the other hand, milk production of the Castro region is well structured even though it has to improve the efficiency and quality of the milk produced.
