- Analyse the problems associated with the cultivation, postharvest management and marketing of selected crops (cotton, oil palm, sisal, coconut and grape) and propose possible solutions
- Analyse the problems associated with the husbandry, postharvest management and marketing of livestock produce and products (goat & sheep) and propose possible solutions
The productivity and profitability of goat and sheep farming depend not only on good animal husbandry but also on effective postharvest handling and marketing. In Tanzania, smallholder farmers often face significant losses at these stages due to a chain of interconnected problems. Analysing these challenges and proposing practical solutions is essential for improving household income and food security.
Husbandry problems occur during the daily management of the flock and directly affect animal growth, health, and survival.
Feed Scarcity and Nutritional Deficiencies
- Problem: Over-reliance on natural pastures and crop residues leads to severe feed shortages during the long dry season (June–October). Animals lose weight, fertility drops, and kids/lambs grow slowly.
- Contributing factors: Lack of fodder banks, failure to conserve hay or silage, and overgrazed rangelands.
- Solution: Establish fodder banks (e.g., planted Leucaena or Gliricidia), harvest and store hay from the rainy season, and use crop residues (maize stover) supplemented with concentrates.
Disease and Parasite Burden
- Problem: High mortality rates from diseases like Peste des Petits Ruminants (PPR) and internal parasites (e.g., Haemonchus contortus).
- Contributing factors: Irregular vaccination, lack of strategic deworming, and wet, dirty housing that promotes parasites.
- Solution: Implement a farm health calendar including annual vaccination for PPR and clostridial diseases, and strategic deworming aligned with wet seasons. Maintain clean, dry housing with proper drainage.
Poor Breeding Management
- Problem: Low kidding/lambing rates and inbreeding.
- Contributing factors: Uncontrolled mating, keeping the same buck/ram for too long, and lack of records.
- Solution: Practice controlled mating (separating males and females), rotate bucks/rams between farms to avoid inbreeding, and keep simple records of mating dates and offspring.
Inadequate Housing
- Problem: Use of traditional thorn kraals or open enclosures that offer no protection from rain, wind, or predators.
- Contributing factors: High cost of proper housing materials and lack of technical knowledge.
- Solution: Construct simple, raised houses with slatted floors (as described in Chapter Six) to keep animals dry and reduce disease pressure.
Postharvest losses occur after the animal is sold or slaughtered and involve handling, processing, and storage.
Pre-Slaughter Handling and Stress
- Problem: Rough handling before slaughter causes stress, which leads to dark-coloured meat (dark cutting) and reduced carcass quality.
- Contributing factors: Long drives to markets, overcrowding, and lack of shade and water at holding points.
- Solution: Handle animals calmly, provide shade and water during fasting, and shorten transport distances where possible.
Slaughter Hygiene and Infrastructure
- Problem: Lack of proper abattoirs; slaughtering on dirty ground contaminates meat and shortens shelf life.
- Contributing factors: Lack of clean water, refrigeration, and sanitation at local markets.
- Solution: Use clean slaughtering slabs, wash carcasses with clean water, and process meat hygienically. Where possible, use ice or cool water baths to lower meat temperature quickly.
Skin Damage and Quality Loss
- Problem: Goat and sheep skins are often downgraded or rejected due to ticks, thorns, branding marks, and rough flaying.
- Contributing factors: Poor parasite control, use of thorn kraals, hot iron branding, and delay in curing skins after slaughter.
- Solution: Control ticks through routine spraying/dipping, avoid branding (use ear tags), and cure skins immediately by dry-salting in the shade. Train slaughterers in careful flaying.
Marketing challenges determine the final price received and the volume sold.
Weak Market Information and Price Volatility
- Problem: Farmers sell when prices are low (e.g., immediately after the rainy season) and lack bargaining power.
- Contributing factors: Seasonal oversupply, lack of market price information, and reliance on middlemen.
- Solution: Use mobile phones to check current prices at different markets (e.g., Makambako or Isiolo). Time sales to coincide with high-demand periods (Eid al-Fitr, Christmas).
Lack of Weighing and Grading
- Problem: Animals are sold "by eye" (estimated weight), leading to underpayment. Buyers demand specific weights, but farmers cannot meet them.
- Contributing factors: Absence of scales at local markets and lack of grading standards.
- Solution: Sell animals based on live weight using portable scales, or finish animals (fatten) for 4–6 weeks to reach target market weights (e.g., 25–30 kg).
High Transaction Costs
- Problem: High transport costs to distant markets and small lot sizes make sales uneconomical.
- Contributing factors: Poor roads, dispersed farmers, and lack of collective bargaining.
- Solution: Form farmer groups (e.g., SACCOs or marketing groups) to pool animals, share transport costs, and negotiate better prices.
Addressing the problems requires an integrated approach across the value chain:
- Production: Establish feed reserves, implement health calendars, and improve housing.
- Processing: Improve hygiene during slaughter and ensure proper skin curing.
- Marketing: Time sales to demand peaks, use weighing scales, and sell collectively to reduce costs.
Case Study: Maimuna's Goat Farm in Shinyanga Maimuna keeps 15 indigenous goats. She faces three main problems:
- Husbandry: Goats lose weight during the dry season (July–September) because there is no grass.
- Postharvest: Her goats often get skin damage from ticks, reducing their value at the market.
- Marketing: She is forced to sell quickly after the rains when prices are low (e.g., TZS 80,000 per goat) to pay school fees.
Analysis:
- Problem 1 (Feed): Caused by lack of feed conservation. Solution: She should plant a fodder bank of Drum grass or Napier grass and cut and carry during the rainy season to store as silage.
- Problem 2 (Skins): Caused by ticks and poor housing. Solution: Spray goats every two weeks during the rains and build a raised house to keep them dry.
- Problem 3 (Marketing): Caused by poor market timing. Solution: She should retain some goats and finish them (feed concentrates) for sale during the dry season when prices rise (e.g., to TZS 150,000) or during Eid.
In everyday life in Tanzania, a student whose family keeps goats in a rural village can use this knowledge to advise on the timing of sales. For example, if a family usually sells five goats in March to pay for school fees, the student can suggest fattening (finishing) two of them for sale during the dry season or Eid when prices are double, thereby covering the school fees more comfortably. Similarly, they can encourage the family to build a simple raised pen to reduce tick burdens and improve skin quality for the local tanner, turning a by-product into extra income.
