Abstract : From weaning 50 ewe lambs were maintained on annual grassland range pasture which provided adequate feed for only 2 or 3 months in spring, followed by a dry season until early winter. This barely maintained weight for 6 months after weaning and allowed a slow gain until breeding the following year. From Julyto April50 similarlambs were kept on irrigated pasture of ladino clover and trefoil supplemented with lucerne hay to appetite from November to April. This promoted continuous growth. They were then transferred to the range pasture and both groups were kept there for 5 to 7 breeding seasons. The only supplement given was a mixture of salt and cottonseed from mating until the end of the dry season each year. Ewes which had been reared on good pasture were 34% heavier as yearlings than those reared on the range and remained significantly heavier until 41/2 years old and in some the difference was still seen at 6 years. They had greater heart girth and height at withers after a year on range and produced significantly more wool at the first and third shearings but at no other. They lambed significantly earlier, 8 days, in the first year; in subsequent years they lambed 2 to 3 days later than the other group. They raised fewer lambs per ewe in the 7 seasons but frequency of twins and weights of lambs at 120 days were the same in both groups. Total weight of lambs per ewe and lambs weaned per ewe were less in those given poor pasture at the start.-J. G. Gordon. |

Bovine mastitis is a problem in the context of animal health. However medicinal plants are a management strategy in agroecological production systems. In this context, the plant Tagetes minuta L. plays a leading role, due to its recognition in the popular pharmacopeia. Thus, the objective of this work was to assess the effect of hydroalcoholic extracts of T. minuta from different collection sites compared to ten bacteria related to bovine mastitis. The antimicrobial evaluation was done through the microdilution technique in syrup, in 96 well microplates in triplicate, for the determination of Minimal Bacterial Concentration (MBC) (%). In the microplates, the extracts of T. minuta and the inoculums of the bacteria were placed in addition to the growth control of the bacteria and the control of the extracts, which were incubated for 72 hours at 37°C in an oven. After this time, aliquots of 5?L of each orifice were transferred to plates containing 5% equine defibrinated blood agar and maintained in incubation for 24 hours at the same previous temperature. With this, the growth readings were performed, with the subsequent interpretation of the results by the geometric mean of the MBC (%). The results indicate that there is a difference in sensitivity to microorganisms by the extracts as a function of the collection sites and both present antimicrobial action. |
