Reproductive efficiency of Nellore cows nursing Nellore or crossbred Simmental x Nellore calves

The objective of this study was to analyze the influence of genetic group (GG) of the calf during gestation, mobilization of body reserves and period of postpartum anestrus in Nellore cows. Thirty-seven primiparous and multiparous cows were used: 24 gave birth to Nellore (NEL), and 13 gave birth to 1/2 Simmental x 1/2 Nellore (SIM) calves. According to the date of calving, cows were divided into three blocks, with intervals of 20 days between blocks. The body condition (BC) of the cows was estimated subjectively on a scale from 0 to 5 points, with intermediate grading of 0.5 points. We measured the thickness of subcutaneous fat (SF) between the 12th and 13th ribs and rump by ultrasound. Blood samples from each cow were collected weekly from the third week after birth until weaning, to analyze the level of progesterone; in the samples collected until 16 weeks postpartum, we analyzed the concentration of nonesterified fatty acids(NEFA). The gestation period of mothers of NEL calves was eight days longer, on average. The variables relating to the mobilization of body reserves (NEFA, BC and SF) were not influenced by calf GG, with the only significant effects being the number of days postpartum, witha peak in the concentration of NEFA between the sixth and eighth weeks and linear decrease in BC and NF. Mothers of NEL calves remained in anestrus for 4.6 weeks longer than the mothers of crossbred calves.

Allonursing in river buffalo, Bubalus bubalis: Nepotism, incompetence, or thievery?

Allonursing was investigated in a dairy herd of 30 river buffalo cows and their calves. The primary behavioural variables were solicitations of allonursing by calves and acceptances of calves by cows. The sample of cows included a group of nine half-sisters, two additional pairs of half-sisters, and a pair of full-sisters. All of the calves were half-siblings owing to putative common paternity. Ancillary variables were age, milk-yield and docility of cows, as well as age, sex, weight and growth rate of calves. Three hundred and fifty-one instances of allonursing and 341 of filial nursing were recorded. There were large individual differences in the cows' tendencies to accept their own offspring and non-filial calves, and for the calves to successfully solicit milk from their mothers and other cows. Thirteen of the 30 cows accounted for 97% of the allonursing. Frequent allonursing was correlated with decreased growth rate in the donors' calves. Allonursing was unrelated to kinship or reciprocal relationships among the cows, and was associated with a lack of maternal experience in young cows and apparent milk theft by hungry calves whose mothers were not providing them with sufficient milk. © 1995 The Association for the Study of Animal Behaviour.
