Researchers need to know how each animal relates to the rest of the group to assess the significance of family ties. Screaming and terrified, a baby monkey intended for use in British laboratories shakes with fear after being cruelly snatched from its parents at a breeding farm. Almond was a long-tailed macaque monkey, and a baby at that. Another female adult was then seen hugging a motherless child.This baby was later saved by the research team and reunited with his mother. But there are concerns this could spiral out of control if there is deregulation and an abandoning of EU rules after A total of 2,606 long-tailed macaques were imported into Britain last year, 2,064 from Mauritius and 542 from Vietnam.In Mauritius ADI filmed pregnant monkeys being manhandled and pinned down, and monkeys swung by their tails at key breeding facility, Biodia.In Vietnam they saw monkeys kept in small rusting cages which were in a state of collapse.Most primates (2,148) were last year used for regulatory safety tests on substances and would endure force-feeding or injections of experimental compounds and full body restraints.To help, ask your MP to back Early Day Motion 2228: Developing Innovative Science – Better for Animals and People.When you subscribe we will use the information you provide to send you these newsletters. But instead of living in the forest with her mom as she should been, Almond was being kept as a pet by a family in Bali, Indonesia.

In another instance, a baby spider monkey was left for dead after a violent attack. If they had not intervened, they say, his injuries were so severe he would have died.The researchers say that attacks from other predators "cannot be discounted" but that the wounds they observed were consistent with other spider monkey attacks.Infanticide also opens up the female to mating again. Under EU law, use of F1s will be phased out by 2023.It seemed the UK Government was moving towards this deadline, with no F1s used in British labs from 2014 to 2016, and just one in 2017.

An animal welfare charity is calling on the Government to act after the heartbreaking video shows a baby monkey being taken away from its parentsWhat is really going on in politics? A female spider monkey typically only gives birth every three years, but this is reduced to 9-10 months if her child dies.That is in line with existing theories about infanticide.

The mother and one of the other males had injuries, suggesting a fight had taken place. While they defeat their enemies one poor baby monkey is … A male was observed being violent towards a mother with a young baby In the current research, Sarah Alvarez from the Complutense University of Madrid in Spain and colleagues studied three different species of spider monkey in Ecuador, Colombia and Belize: In one case, a male was observed being violent towards a mother, named Kuao, with a young baby. The researchers now believe that it may be more common than was originally thought.The study also suggests that their observations could now explain the female-biased sex ratios that spider monkeys groups are known to have.Instances of infanticide are extremely difficult to capture and require detailed and long-term field studies. Published on Sep 20, 2012 This troop of Macaque Monkeys battle to protect their Indian temple home from a rival troop. A total of 246 offspring of wild-caught monkeys, known as “F1” primates were used in UK labs last year, accounting for some 10 per cent of primate use. The mother and one of the other males had injuries, suggesting a fight had taken place. A day later he died from his injuries. But a new study of spider monkeys has found that, in this species, only the male infants are targeted. Although no aggression was observed towards the child at that time, seven days later he was found crying on the forest floor with many cuts and open wounds.
