Ticks, Demographics, Vegetation Cover, and Farmer’s Age Influence Red Meat Production in Resource-Poor Regions of Eastern Cape Province of South Africa ()
1. Introduction
The overall demand for the livestock product is greatly increasing by contributing 30% of agricultural products and 2.5% to the country’s Gross Domestic Product in South Africa [1] [2]. In the nine provinces of South Africa, the Eastern Cape Province (ECP) is endowed with different agro-ecological zones for crop and livestock production. Biomes such as Albany Thicket, Forest, Fynbos, Grassland, Indian Coastal Belt, Nama-Karoo, Savanna and Succulent Karoo in the ECP [3], make the ECP second in terms of the land size (168,966 km2). About 80% of the land is suitable for a larger herd of cattle, sheep, and goats production [4]. Currently, agricultural practices involving communal farming systems do not have an adequate monitoring system that controls the availability of grazing resources, coupled with poor animal husbandry practices that have resulted in lower offtake per annum [5].
Through interacting with farmers and previous records, we found several reasons such as inadequate infrastructure, costs of inputs, poor funding, overstocking and overgrazing, degraded natural resources, low reproduction rate, insufficient extension and veterinary services, limited access to the market, tick burdens and disease prevalence, influencing communal farming in this region [6] [7] [8] [9]. In spite that the effort of the National Development Plan (NDP) for 2030 in South Africa involves agricultural practices that will create millions of jobs for the youths in the rural community [10], previous records (e.g. [6] [7] [8] [9] ) found that the involvement of youths in agricultural practices such as farming and livestock production remains insufficient. Besides that, the communal farming system is hampered by the condition of the rangeland animals use to graze. For instance, the invasion of grazing fields by alien plants e.g. Acacia species, Acacia mearnsii, and the Vachellia karroo that pose a serious threat to fodder production [3] [11], and the occurrence of ticks and tick-borne diseases (TBDs) have been obstructing production in this region. Ticks of the genera Amblyomma, Hyalomma, Rhipicephalus including the subgenus Boophuilus [12] and tick-borne diseases (TBDs) such as babesiosis anaplasmosis, and theileriosis [13] [14] [15] are common to ruminants of the ECP. The buying and movement of cattle promote tick distribution to a new environment. For instance, the spread of the invasive tick (Rhipicephalus microplus) in the ECP has displaced the indigenous tick (R. decoloratus) [15] [16]. Despite these factors, continuity in monitoring is limited, therefore, the objective of this study is to determine the factors that could influence beef production in communal farming areas of the ECP.
2. Materials and Methods
2.1. Study Area
The ECP is a rural area located between the Western Cape and KwaZulu-Natal provinces. The region occupies about 13.9% of South Africa’s land area and it is the second largest after the Northern Cape. The ECP is divided into two metropolitan municipalities (Buffalo City and Nelson Mandela Bay) and six DMs, namely Alfred Nzo, Amathole, Chris Hani, Joe Gqabi, Oliver Reginald Tambo (O. R. Tambo) and Sarah Baartman (Figure 1). The district municipalities are further divided into 31 local municipalities. The climatic condition of the ECP involves a bimodal rainfall pattern that includes a winter rainfall and a summer rainfall [3] [17]. The rainfall in the province varies between 100 mm and 520 mm per annum. During winter, temperature ranges from 7˚C to 20˚C, while in summer, temperature ranges from 16˚C to 26˚C. Of the six DMs, five are involved in farmer profiling and red meat production. With the province having a total of 16 custom feeding centres that are communal based in livestock production of cattle and sheep, thus, ticks were screened from these six DMs.
2.2. Socio-Demographic Profile
An attempt was made to interview 10 - 15 farmers per local municipalities of the participating DMs. Data on demographic factors were collected using questionnaire for 271 farmers involved in farming commodities in Alfred Nzo (n = 51), Amathole (n = 54), Chris Hani (n = 57), Joe Gqabi (n = 50) and O. R. Tambo (n = 59). The information regarding red meat production was obtained from the farmers and the custom feeding centers located in the participating DMs.
2.3. Vegetation Sampling
In each DMs (Alfred Nzo, Amathole & Chris Hani), a group of communal

farmers were granted farms under the program known as Land Redistribution for Agricultural Development (LRAD) for the production of cattle, sheep and goats Of the five participating DMs, veld condition was conducted between nine and 10 farms per district randomly selected to show rangeland productivity. At each site, three 100 m parallel transects were laid out 25 m apart. Botanical composition and the basal cover of the herbaceous layer were assessed using the step point method and within belt transect, woody plant species were identified and counted to evaluate their composition [18].
2.4. Tick Collection
Ticks were screened from five cattle selected randomly in twenty diptanks found across the six DMs visited. The ears, bodies, bellies, feet, tails and peri-anal regions of the animals were screened once in every visit to the DMs. The ticks collected were stored in well labelled vials containing 70% ethanol, before transporting to the Döhne Agricultural Development Institute in Stutterheim and identified on a stereoscopic microscope. In the laboratory, ticks were identified based on morphology [19] and the aid of taxonomic keys of [20] and the reference ticks found in the museum of the University of Pretoria.
2.5. Data Analysis
Data for farmer’s demographic and farming commodity were subjected to [21], version 9.1 for analysis. Frequencies were determined using the PROC FREQ procedures [21]. The chi-square test was used to determine associations between the farmer’s demographic information and farming commodities. Correlation coefficients for farmers’ demography and their farming commodities were determined using PROC CORR procedures of [21]. In all cases, 95% confidence intervals and p < 0.05 were set for statistical significance. Meanwhile, geographic coordinates of each sampled site for ticks were used to plot the distributions of tick species in QGIS v 2.6.1 [22].
3. Results
3.1. Custom Feeding Centers Distribution
In an endeavour to collect information on red meat production for communal farming areas, a survey on customer feeding centers was done in five DMs (Figure 1). All the custom feedlot centers were visited and data regarding intake capacity was recorded. However, none of the 16 centers have achieved 100% operational status when comparing intake capacity with current numbers of animals. From the 271 farmers interviewed across the five DMs, the common challenges for red meat production were lack of marketing channels (23%), poor animal conditions (20%), lack of infrastructure (19%), high price of medicine (14%), shortage of feed (10%), stock theft (8%), and age of animals (too old) to be marketed (6%).
3.2. Farmers’ Socio-Demographic Profile
Table 1 shows the demographic profiles of 271 farmers who participated in the study. The majority of the respondents were males (67%) compared to females (33%). The highest numbers of farmers (26%) were between ages 41 - 50 years old, proceeded by 51 - 60 years old (21%). Most of the (32%) farmers were between 21 - 25 years of farming experience, proceeded by 16 - 20 years (15%), 11 - 15 years (18%), above 26 years (13%) and less than 5 years (10%). the farmer’s demography and farming commodities were conducted and there was a significantly strong correlation (p ≤ 0.001) between farming commodity and farming area (Table 2). We also found that farming commodities (such as livestock, poultry and piggery) were significantly influenced by gender and farming experience while age was not significant (p > 0.05).
3.3. Vegetation Assessment
Results from Tables 3-5 indicate the condition of veld in the three surveyed districts (Alfred Nzo, Amathole and Chris Hani Districts). It was observed that numerous farms were overstocked per each district during the survey. About 80% and 70% of farms in Alfred Nzo (Table 4) and Chris Hani District (Table 3) were overstocked, while the understocked (80%) farms were found in Amathole

LRAD (Table 5). Based on vegetation assessment of the farms, a greater proportion of increaser II grass species were observed in Alfred Nzo (55.6%), Amathole (53.9%) and Chris Hani (46.4%) DMs. The decreaser grass species were much lower in Alfred Nzo (16.5%), Amathole (13.8%) and Chris Hani (21.8%).
3.4. Tick Species, Prevalence and Distribution
A total of 34,929 ticks belong to five genera and 10 species were identified from 600 cattle. The most abundant tick genera was the Rhipicephalus including subgenus Boophilus (68.91%), proceeded by Amblyomma (20.72%), Hyalomma (8.64%), Ixodes (1.22%), and Haemaphysalis (0.51%). The geographic distribution of most encountered ticks such as A. hebraeum (Figure 2), R. (B.) microplus, (Figure 3), R. evertsi evertsi (Figure 4) and R. appendiculatus were illustrated (Figure 5).
3.5. Discussion
Beef in the ECP is useful to both communal and smallholder productions. Communal farming system is characterised by farming within a common ground and as such, no one is having ownership of the land. Through LRAD programs, farmers that have shown great interest in emerging from communal to smallholder production are assisted and encouraged to apply for LRAD farms. Since the ECP is largely communal farming, South Africa embarked on the Red Meat Program in 2005 to promote marketing of livestock that involves beef production called

the Eastern Cape Red Meat Project. This project was later (in 2008) taken up by National Agricultural Marketing Council (NAMC) and funded by Department of Rural Development and Land Reform (DRDLR) which led to the expansion to other provinces of the country [23].
We found that the factors obstructing beef meat production include marketing channels, poor animal conditions, lack of infrastructure, high price of medicine, shortage of feed, stock theft, and old animals to be marketed. Other studies from the ECP [24] [25] included that farmers were not satisfied with the low market prices they get from the auctions. This may be as a result of the large herd of the animals (cattle) which are in poor condition. As a way to improve communal or smallholder herd, 16 customer feeding centers were developed around the ECP to fatten cattle, therefore to improve the market price by weight gained. We found in line with a previous study, the poor supply of infrastructure for smallholder production is of great concern, thus, hampering the growth of smallholder production system [26] [27]. This could be attributed to differences in channels of marketing. For instance, the private sales are done for local people among neighbours and neighbouring communities mainly for cultural ceremonies or income for clearing fees for learners. In this regard, farmers do not experience any transport cost for dealing with the private sale.
Whereas in auctions, animals must be registered and be correctly identified through branding or tattooing with the owner’s brand. Communal farmers usually suffer due to high transactional costs of selling or buying from auctioneers.
The socio-characteristics from the respondents in the ECP showed that males were higher (67%) compared to females (33%) in livestock rearing of ruminants [28] [29]. The participation of youth in farming is still a challenge but is improving and as a result, we found that 32% of farmers were between 21 - 25 years of farming experience, although the highest number of farmers (26%) were between the ages of 41 - 50 years old, proceeded by 51 - 60 years old (21%). From this study, it is quite interesting to find out that more youths participated in agricultural activities in contrast to other previous records [30] [31]. More so, this study found a strong positive relationship between livestock farming and farming commodities.
In communally grazed area, the main source of nutrition is through forage on the veld and the animals extensively graze with no supplementary feeding. Species composition has been used to assess basal cover and production potential of the grasses on the veld. In turn, the veld condition gives information about the grazing capacity. Thus, from the ecological group of grass species encountered, the veld is in a good condition. Using the LRAD farms visited across the different DMs, we witnessed that numerous farms were overstocked in places like Alfred Nzo (80%) and Chris Hani (70%) DMs. A poor veld condition has been attributed to high stocking rates and continuous grazing [32] [33]. More so, Alfred Nzo and Chris Hani occur on a Grassland biome compared to Amathole district that is on a Savanna biome with main trees, bushes and grasses. Our findings showed that most of the Amathole district farms were understock (80%) and this may be due to the differences in the agro-ecological zones. Also, despite being understocked, assessment showed mismanagement of the veld increaser II grass species (e.g. Aristida congesta, Eragrostis curvula and Sporobolus africanus) [3]. Increaser species is an indication of poor veld condition as result of light, moderate or heavy overgrazing [11]. Likewise, a veld in good condition is characterised by dominance of decreaser grass species (e.g., Digitaria eriantha, Panicum maximum and Themeda trianda). All assessed farms have low numbers of decreaser species. Land degradation is caused by overgrazing on communal rangelands [34] and this has threatened both communal and commercial properties with an estimated value of US$40 billion per annum [35]. Indirectly, this contributes to lower production and poor performance in beef production.
In any farming system, ticks and tick-borne diseases threaten livestock production. In the present study, ticks of the genus Amblyomma, Hyalomma, Rhipicephalus and subgenus Boophilus were encountered. These genera are comprised of tick species of major concern in the livestock sector of South Africa [11] [12] [15]. Our study found that Rhipicephalus including subgenus Boophilus were most numerous ticks which were prevalent at 68.91%, proceeded by South African bont tick i.e. Amblyomma (20.72%), and Hyalomma (8.64%). Based on tick distribution (Figures 2-5), the brown ear tick i.e. R. appendiculatus attaches to the ear of a host and also causes corridor disease and East Cost Fever (ECF) in Africa [20]. Another tick species of interest is the R. evertsi evertsi which normally affects the perineum region causing loss of blood from a host. Tick species such as the A. hebraeum and H. rufipes are characterised by medium to long mouth parts that are capable for damaging the skin of the host [20]. Apart from this, A. hebraeum is among the major occurring ticks in ECP and is causing heart water disease (Ehrlichiosis) in ruminants. On the other hand, a one host tick, R. microplus has a wide distribution in the province and has replaced the indigenous tick (R. decoloratus) in most parts of the country [15] [16] [36]. The R. microplus is also causing huge stress in cattle farming by vectoring the African red water and Asiatic red water (bovine babesiosis) in a host [15]. Records have found with surprise, that both A. hebraeum and R. microplus are now prevalent on the inland of the ECP [12]. Previously, tick species such as R. microplus were not usually found in the cooler region of the ECP [15]. In communal rangelands, government provides chemicals to control ticks weekly during the summer and winter when ticks are much. Conversely, when resources from government are scarce, tick burden becomes intense thereby causing mortality of the host [25] [37].
4. Conclusion
The study outlined constraints faced by low input-farming areas and is bringing solutions that can be used to improve the farming conditions. Most farming areas are overgrazed and invaded by unpalatable species such as Increaser grass species. The poor conditions play a role in poor animal performance in terms of production and poor body conditions. This is compounded further by ticks and TBDs. There is a need for more tailored interventions which encourage government and stakeholders to assist farmers for infrastructure development, to get access to the credit, improve marketing channels so that they might be able to compete in the commercial sector. If the aforementioned constraints can be resolved, the low-input farmers can achieve competitive levels of production. This will then translate to the sustainable development goal of South Africa to alleviate poverty and reduce inequality in agriculture. However, it is recommended that farmers farm according to their carrying capacity and stocking rate, where government rangeland scientists provide assistance free to farmers.
