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

Rapeseed (Brassica napus L.) is the second most produced oilseed crop in the world. It provides a high-quality nutrient for pollinating insects, and pollination, in many cases, increases crop yield. Although a large number of species visit rapeseed crops, Apis mellifera (Hymenoptera: Apidae) is the most frequent, abundant, and with the highest pollination potential. Our aim was to evaluate the effect of A.mellifera on the different yield components of Brassica napusL. (cv. Rivette). The hypothesis of the study was that the presence of pollinators would increase rapeseed crop yield and improves maturation uniformity. Four trials were conducted (one in 2013, two in 2015, and one in 2016) in commercial rapeseed crops, using pollinator exclusion tents placed during the flowering period. A randomized complete block design with two treatments and six replications during 2013 and three replications during 2015 and 2016 was used. Treatments consisted of exclusion tents with the addition of an active beehive (WITH) and without a beehive (EXCLUDED). WITH treatments showed greater uniformity on siliques maturation and a lower proportion of flowers at maturity. Rapeseed yield was determined by the site (season and farm) (P < 0.0005) and treatments (WITH or EXCLUDED) (P = 0.0482), with no interaction between them (P = 0.1217). Grain yield in WITH treatments was 14% higher than in EXCLUDED treatments (2089 vs. 1836 kg ha?1). In 12 out of 15 (80%) experimental units, WITH treatment yields were higher than EXCLUDED treatments. Results show that A.mellifera can increase rapeseed yields, despite a high rate of self-fertilization.
