“…Reproduction can be negatively affected in many ways (Bellows & Short, 1994). Retained placentas and cesarean delivery can result in a prolonged postpartum interval to conception, causing increased days open and decreased milk production (Barkema et al, 1992;Van Werven, 1992). Infertility regardless of cause is a major reason for culling the animals.…”

Reproductive problems among dairy animals are one of the major causes of loss in dairy sector. These problems can be tackled by imparting appropriate knowledge to the livestock owners. An attempt was made to measure the knowledge of livestock owners by developing a knowledge test on reproductive problems of dairy animals. The study was undertaken in Karnal district of Haryana state, India. Data were solicited from 300 livestock farmers who had at least one milch animal at the time of investigation. In addition to developing schedules for socio-economic variables, a knowledge test was also developed for measuring knowledge construct. Data were solicited on scientific treatment of affected dairy animals and 59.54% knowledge was observed on reproductive traits. Study indicates that majority of livestock farmers adopted scientific methods for treating their animals. Respondents' age, extension contact and milk production were positively and significantly correlated with knowledge. Therefore, imparting quality practical training and periodical assessment of performance of lay inseminators for improving their skills and knowledge regarding estrus detection and insemination needs to be emphasized. Extension machinery has to be an ideal bridge between research/development institutions and dairy farmers for their catalytic effect (Meena & Malik, 2009). Extensive awareness programs are needed for inculcating scientific outlook among livestock farmers on these complex problems. Easy accessibility of veterinary hospital at village level can reduce the adoption of indigenous technical knowledge in treatment of these complex problems.

“…[6] However, caesarian sections are not very common on Dutch dairy farms although one study mentioned percentages per farm ranging from 0 to 3.6%. [15] Based on this, findings of isoxsuprine in calves' hair should be rare, if found at all.…”

“…In healthy human volunteers, the absorption of isoxsuprine was assumed to be about 51%,14 and for horses, oral bioavailability was found to be 2.2% with a high first‐pass effect 6.

Isoxsuprine is a beta-agonist that can be used for growth promotion in cattle, but it is also used as registered veterinary medicine. To investigate if veterinary treatment of cows could lead to residues of isoxsuprine in the hair of their newborn calves, an animal experiment was performed. Four cows, treated on veterinary indication with isoxsuprine lactate (Duphaspasmin) before a caesarian section, were included in the experiment. Hair samples from cows and from their calves were analyzed. The animals were shaved every week for 16 weeks and levels of isoxsuprine were measured in hair. In the cows, the levels of isoxsuprine were highest (>15 µg/kg) just after administration of the isoxsuprine lactate. After two weeks in two cows, a sort of plateau was reached and then the levels decreased. After approximately 10-15 weeks the levels were around the CCα level of the method used (0.5 µg/kg). In calves, for the first two weeks after birth, no isoxsuprine was found above CCα level in three of the four animals. At about 20-30 days old, a maximum concentration of 4 µg/kg was found. Then the levels dropped again under the CCα level, after 60 days no levels above CCα level were found. In one animal, the levels never reached CCα level. We conclude that veterinary treatment of cows with isoxsuprine may temporarily lead to low levels of isoxsuprine in the hair of their newborn calves which can be measured for a maximum of 60 days after birth.

“…Elective caesarean is sometimes performed on small heifers or dams carrying large calves. Waiting for full cervical dilation, even in elective caesarean section, is recommended before performing surgery, as it promotes postnatal respiratory and metabolic adaptation (Barkema et al, 1992b). There are some advantages to embryotomy: speedier, safer and less exhausting to animal and operator (Arthur, 1982).…”

“…Risk factors for caesarean section consist of first parity, single male calf, long gestation period, long interval between first service and conception, long dry period, sired by a bull of double-muscled structure, under 730 days of age at first calving, and having a previous cesarean section (Arthur, 1982;Barkema et al, 1992b).…”
