Abstract: This experiment tested the hypothesis that a lift in the nutrition of ewes, before lambing, to increase colostrum production
would enhance lamb survival. In all, 261 mature Corriedale ewes, each with a single fetus from a synchronised mating, grazed
native pasture to day 130 after mating; at which point they were weighed, condition scored and allocated to graze either
native pasture or a pasture dominant with Lotus uliginosus. Five days later (14 days before the expected start of lambing)
the ewes were allocated to one of four treatments and fed: (i) native pasture alone, (ii) native pasture plus a commercial
high-energy lick, (iii) L. uliginosus pasture alone or (iv) L. uliginosus pasture plus whole maize. The weight, viscosity and
concentration of components and immunoglobulin G in the colostrum that had accumulated at parturition, were measured
for 10 ewes in each treatment. The lambs that survived to 20 days of age from the 221 ewes that were not milked, were
recorded. The ewes supplemented with the lick or maize grain and those that grazed the L. uliginosus pasture alone
accumulated two to three times more colostrum at birth than the ewes that grazed native pasture alone (396, 635 and 662 g v.
206 g; P , 0.01). The colostrum from the ewes that grazed only native pasture was more viscous (lower score) than that from
the ewes supplemented with the lick or maize grain or the ewes that grazed the L. uliginosus pasture alone (scores of 4.1 v.
6.2, 6.5 and 6.4, P , 0.001) and, not surprisingly, the concentration of lactose in the colostrum of the ewes fed only native
pasture was also much lower (1.1% v. 3.0%, 2.8% and 2.6%; P , 0.001). The survival of lambs from the ewes fed only native
pasture was less than that of the lambs from ewes fed native pasture plus the commercial lick (81.8% v. 95.5%; P , 0.05)
or the L. uliginosus pasture alone (92.4%, P , 0.05), and also tended to be lower than that for lambs born to ewes fed
L. uliginosus pasture plus maize (91.8%, P 5 0.08). The concentration of glucose in the blood of the lambs from the ewes
that grazed only native pasture was lower than that of the other lambs (42.1 v. 60.2 ng/ml, P 5 0.012). We conclude that the
marked increase in colostrum production associated with the lift in ewe nutrition, just prior to lambing, enhanced lamb survival MenosAbstract: This experiment tested the hypothesis that a lift in the nutrition of ewes, before lambing, to increase colostrum production

Abstracts. Uruguay is a leading exporter of bovine meat and dairy products, and cattle production is one of the principal economic backbones in this country. A main clinical problem faced by livestock farmers is neonatal calf diarrhea (NCD); however, causes of NCD have not been extensively studied in Uruguay. Bovine norovirus (BoNoV) has been proposed as one of the possible etiologies of NCD as experimentally infected calves developed diarrhea and enteropathy, although limited information is available from field surveys. The aims of this study were to
determine the frequency of infection, to investigate possible risk factors, and to determine the molecular diversity of BoNoV in Uruguay. A total of 761 samples of feces or intestinal contents from dairy and beef calves were analyzed through RT-qPCR. The overall frequency of detection of BoNoV was 66.1% with higher frequency in dairy (70.5%) than beef (15.9%) calves (p < 0.01). BoNoV was detected similarly in diarrheic (78.8%) and non-diarrheic (76.2%) dairy calves (p = 0.50). Calves ?2 weeks of age (84%) were infected more often than older
(62.7%) calves (p < 0.01). Phylogenetic analysis confirmed the presence of GIII.1 and GIII.2 genotypes. In addition, we reported the circulation of recombinant strains and the detection of a strain with the recently described novel VP1 genotype. This study represents the first report describing the circulation, the associated risk factors, and the molecular diversity of BoNoV in Uruguay. |
