Poisonous plants of regional importance

Page 2: Common  Plants  Poisonous to Livestock

Poisonous plants - Poisonous as such : containing toxic

substances – phytotoxins- toxic to the animals

Not toxic as such ; become toxic under unfavourable conditions to the animal- season, stage of the plant growth, hunger, management , practices

Page 3: Common  Plants  Poisonous to Livestock

Phytotoxins-toxic principles present in the plant

Predisposition Fodder scarcity New areas Loss of sense of discrimination Malicious poisonong Lack of information/knowledge

Page 4: Common  Plants  Poisonous to Livestock

Classification

Organic phytotoxins by-products of plant metabolism. Eg: alkaloids , glycosides,essential oils, terpenes, proteins, and resins etc. Inorganic phytotoxins fluorides, nitrates and selenium compounds merely accumulate in the plant due to their translocation from the soil and water rich in these substances.

Page 5: Common  Plants  Poisonous to Livestock

Factors affecting the phytotoxicity

Region/place Stage of growth Part of the plant Quantity ingested Climate Soil composition Size Age Sex Prevailing health/ nutritional status of the animal Management practices- use of fertilizers etc

Page 6: Common  Plants  Poisonous to Livestock

Clinical condition

Acute Gastrointestinal and nervous signs predominant. Off-feed, colic, bloat, diarrhoea mixed with blood and mucous, salivation, CNS signs - convulsions, paralysis , coma , deathChronic Not fatal, affects the economy of farmer Fall in production and fertility of animals. Allergic dermatitis, photosensitisation, Haemoglobinuria and agalactia

Page 7: Common  Plants  Poisonous to Livestock

Diagnosis History and Information on feeding practices Survey of the grazing area and farm premises Symptoms, botanical and toxicological Analysis of hay, forage, silage or suspected

plant material.Materials to be sent to the lab Fresh plant material Whole fresh plant if it is small, Leafy branch with

flowers In case of large plants and trees- uncrushed bulky

parts-root, fruits in a plastic bag Dried plant material in a rigid cardboard box taking care not to break

branches/detach leaves

Page 8: Common  Plants  Poisonous to Livestock

Treatment Adsorbents like charcoal, raw white of an egg

orally Antiserum (if the causative phytotoxin is

specifically known) Specific antidotes whenever available Symptomatic treatment- administration of

astringents, antispasmodics, anticonvulsants, fluid therapy, liver tonics, etc.

Prevention• Drying of plants • Caution while stall-feeding• Manual removal of poisonous plants and weeds

from the farm premises

Nitrate/Nitrite accumulating plants

Page 82: Common  Plants  Poisonous to Livestock

Crop sources: a) Oats - Avena sativa( seeme oats, seeme thoke

godhi) especially if green hay or green chop and left on the wagon overnight before feeding. The forage heats up and converts nitrate to nitrite before it is eaten. Oats are no longer toxic after the grain forms.

b) wheat - Triticum aestivumc) barley - Hordeum vulgare d) Corn - Zea mays e) rye - Secale cereale f) Beta vulgaris g) rape - Brassica napush) soybeans - Glycine maxi) Flax- Linum usitatissimum j) alfalfa - Medicago sativak) Sudan grass- Sorghum vulgare.-

Acute toxicity Digestive symptoms –vomition, diarrhoea, colic and

frequent urinationRespiratory symptoms like dyspnoea, cyanosis, rapid

& weak pulse weakness, trembling, collapse, coma, terminal clonic

convulsions and death Chronic toxicityAnorexia, decreased body weight gain, reduced milk production, weakness, abortions, birth of weak & stunted calves, poor conception rate, hypovitaminosis of A, D, E thyroid dysfunction .

Page 84: Common  Plants  Poisonous to Livestock

Treatment: Methylene blue 1% w/v solution, @ 8.8 mg/Kg body

wt. slow I/V.for cattle and sheep. In other species the dosage is 4.4 mg/Kg body wt. slow I/V. Repeat after 30 min. if symptoms persist.

Saline purgatives  Broad-spectrum antibiotics in 8-19 L cold water to

inhibit microbial conversion of nitrate to nitrite. For chronic toxicity o Eliminating the source o Supplementation with vit. A D & E.o For prevention, indiscriminate use of nitrogenous

fertilisers like urea to forage crops to be avoided
