More specifically, they practice polygyny. According to our text book, "Principles and Applications of Domestic Animal Behavior", in polygyny, males have multiple mating partners. 
-Like beef cattle, many elephant species practice polygyny. These bonds are either temporary or non-existent and care of the offspring is not shared. ]]> 2017-03-06 04:25:44 UTC https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157919019 katewangs22 https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157920427 According to www.botswana.co.za, "Many elephant species adopt a bachelor herd policy whereby males that have reached sexual maturity will be chased out of a breeding herd by the dominant male or female and will join up with a group of males-bachelor herd-and here they will compete with the others to establish dominance." ]]> 2017-03-06 04:45:03 UTC https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157920427 katewangs22 https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157921412 Bull, cow, and calf are used for BOTH beef cattle and elephants.

Female-female mounting is also an obvious sign displaying that the female is sexually ready. ]]> 2017-03-06 05:31:12 UTC https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157922973 katewangs22 https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157923317 From www.seaworld.org, "Reproductive receptiveness is often displayed in females by greater interest and enthusiasm at the approach of a bull." Females will also perform an "estrous walk". Here, the receptive female will hold their head high and frequently look over their shoulders. They will also vocalize which helps males locate them. ]]> 2017-03-06 05:37:44 UTC https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157923317 katewangs22 https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157924081 2017-03-06 05:50:42 UTC https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157924081 katewangs22 https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157924276 Elephants use male-male competition along with female choice as the deciding factor of who they will mate with. In the wild, male elephants will push, ram, tusk, and wrestle each other. The weaker of the two will retreat and give up mating rights. https://www.bing.com/videos/search?q=elephants+fighting+&&view=detail&mid=E29509F7E42DF2F65BC2E29509F7E42DF2F65BC2&FORM=VRDGAR]]> 2017-03-06 05:53:00 UTC https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157924276 katewangs22 https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157925024 Male-male competition and female choice are eliminated when it comes to mating systems in cattle. Since cattle are domestic animals, their breeding is virtually all controlled by humans. According to our text, "The loss of female choice when the animal breeder, rather than the animal itself, chooses it's mate ("forced" pairings) can increase the incidence of behavioral incompatibility and breeding failure greatly."]]> 2017-03-06 06:02:44 UTC https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157925024 katewangs22 https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157925917 2017-03-06 06:13:22 UTC https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157925917 katewangs22 https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157925989 The gestation period for elephants is two years (20-22 months). From www.seaworld.org, "As the time of giving birth approaches, the female will seek close contact with another female in her family unit for protection during labor." A single calf is usually born head and forelegs first. Twins are extremely rare. On average, newborn calves weigh around 265lbs but can weigh as much as 365lbs. ]]> 2017-03-06 06:14:15 UTC https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157925989 katewangs22 https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157926546 The gestation period for cattle is around nine months. When the female starts the calving process, she will generally separate herself from the group. In normal calving situations, the calf is born head and forelegs first. There is usually a single calf but twins do occur. Birth rates can vary from 70lbs-95lbs depending on the breed. ]]> 2017-03-06 06:23:07 UTC https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157926546 katewangs22 https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157929837 https://www.researchgate.net/profile/Joyce_Poole/publication/222028670_Mate_guarding_reproductive_success_and_female_choice_in_African_elephants/links/02e7e538ef40c6b932000000/Mate-guarding-reproductive-success-and-female-choice-in-African-elephants.pdf]]> 2017-03-06 07:05:12 UTC https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157929837 katewangs22 https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157930745 https://minerva-access.unimelb.edu.au/bitstream/handle/11343/39540/81406_748.pdf?sequence=1]]> 2017-03-06 07:14:43 UTC https://padlet.com/katewangs22/h9kf9i0t2y8j/wish/157930745
