‘BLOOD LIONS’: Report on captive lions reveal countless number of physical and mental problems

Poor hygiene and inadequate food, the study found, most likely contributed to a broad spectrum of diseases and clinical symptoms, including autoimmune, gastrointestinal, respiratory, musculoskeletal and neurological conditions.

DON PINNOCK: In South Africa, up to 8,000 lions are being raised in nearly 400 commercial captive breeding facilities. Every now and then the NSPCA is called in by a concerned neighbour or a conservation organisation snaps some distressing pictures. There’s very little control and no scientific studies on the effect of permanently caging wild lions or holding them on commercial farms.

In trying to get a scientific handle on this widespread industry, the NGOs Blood Lions and World Animal Protection embarked on a global search for hard facts on captive lion welfare. The results are disturbing.

Using a novel method, six wildlife scientists reviewed terms related to negative behaviour and health across 91 global studies on lions in captivity. Most of these are related to disease and injury, followed by negative behaviour, mental stress and nutritional concerns. What concerned them was a virtual absence of studies on captive lions in South Africa, a reflection of the hostility of breeders to any interference from “outsiders”.

Lions are bred for tourism interactions like cub petting and voluntourism, trophy hunting or to harvest their body parts (mainly bones) for local and international traditional medicine practices. They’re kept for purely commercial, not conservation reasons…

For many years, criticism and concern have focused on the negative animal welfare impacts and unregulated nature of the industry. When bones are the trade item, the condition of the lions they bear is irrelevant to breeders. Inspections of 95 lion farms during 2016-17 by the National Council of Societies for the Prevention of Cruelty to Animals (NSPCA) found that nearly half of the facilities were housing lions in substandard conditions…

Across the 91 papers reviewed for the Blood Lions/World Animal Protection study, a startling 170 different terms relating to negative aspects of captive lion welfare were identified. The issues cited included self-mutilation, abnormal pacing, unnatural aggression, chronic stress, anxiety, irritation and neuroticism and antagonistic behaviour leading to injuries, most likely from inadequate environmental conditions such as overcrowding.

Poor hygiene and inadequate food, the study found, most likely contributed to a broad spectrum of diseases and clinical symptoms, including autoimmune, gastrointestinal, respiratory, musculoskeletal and neurological conditions.

Nutrition-related concerns included anaemia, dehydration and nutrient deficiencies. This, say the authors, could lead to mechanical issues such as malformation and spinal cord degeneration. Dental decay was also a problem. In addition, raising lions in small captive populations can lead to inbreeding, which increases susceptibility to infectious diseases such as bovine tuberculosis…

The premature separation of mothers and cubs and the subsequent bottle-feeding of cubs on alternative milk formula that lacks essential amino acids, such as taurine, and is deficient in vitamin A, is also practised at commercial breeding facilities. The resulting nutritional deficiencies can compromise the immune system and leave animals more susceptible to pathogens…

According to the study, there are anecdotal reports of “lion abattoirs” where lions are slaughtered by tranquillising and shooting them through the ear rather than the cranium to preserve the integrity of the skull for buyers…

This is the list of conditions and diseases cited in the studies the report perused relating to lions in captivity. It’s not easy reading, but it tells a story that needs to be known.

Physical problems include:

Weight loss, anaemia, loss of condition and body weight, advanced emaciation, vitamin A deficiency, stress from surrounding environment, range restriction, restriction of opportunity for social contact, disturbed daytime and night-time behaviours, abnormal pacing, stress caused by visitor presence, display of aggression, self-harm, head tossing, auto mutilation, faeces licking, refusal of food, reduction in complex and exploratory behaviour, dragging of the hind paws, neuroticism, impulsiveness, fright, distress, frustration, boredom, fearful, suspicious, tense, insecure, constrained, fearful of conspecifics, timidity.
