PROBLEM: Paragraph: Objectives: Cow and calf performance in a semi-confined cow-calf production system was compared with total confinement using summer-born calves. Material and Methods: The experiment was conducted over 3 yr in eastern Nebraska (ENREC) and 2 yr in western Nebraska (PREC) in a randomized complete block design. Lactating, crossbred beef cows (n = 127 at ENREC; n = 56 at PREC) with summer-born calves were used from November to April. Treatments were (1) drylot feeding or (2) cornstalk grazing with supplementation. Dry-lot pairs were limit fed a crop residue and distillersbased diet to meet energy requirements of a lactating cow. A dried distillers grain-based pellet was supplemented to pairs on cornstalks at a rate of 2.4 kg of DM/pair daily. Dry-lot cow-calf pairs were limit fed 12.1 kg of DM/d throughout the trial. Results and Discussion: At ENREC, cows wintered on cornstalks lost BW and had a 0.46-unit decrease in BCS (P < 0.01), whereas cows in the dry-lot gained BW and had a 0.24-unit increase in BCS. At PREC, BCS increased by 0.03 units for cows wintered in the dry-lot and decreased by 0.26 units for cows wintered on cornstalks (P < 0.04). At both locations, calves fed in a dry-lot had greater ADG and BW per day of age compared with calves offered cornstalk grazing with supplementation (P ≤ 0.03). Implications and Applications: A partial budget suggests that lower winter production inputs compensate for reduced performance of calves when cow-calf pairs are wintered on cornstalks, making residue grazing a viable option in partial confinement systems.

SOLUTION: False

PROBLEM: Paragraph: Some stem cell lines may contain an endogenous virus or can be contaminated with exogenous viruses (even of animal origin) and may secrete viral particles or express viral antigens on their surface. Moreover, certain biotechnological products (e.g. bovine fetal serum, murine feeder cells) may contain prion particles. Viral and prion contamination of cell cultures and ''feeder'' cells, which is a common risk in all biotechnological products derived from the cell lines, is the most challenging and potentially serious outcome to address, due to the difficulty involved in virus and prion detection and the potential to cause serious disease in recipients of these cell products. Stem cell banks should introduce adequate quality assurance programs like the microbiological control program and can provide researchers with valuable support in the standardization and safety of procedures and protocols used for the viral and prion testing and in validation programs to assure the quality and safety of the cells.

PROBLEM: Paragraph: The primary objective of this randomized controlled trial was to determine whether anti-IL-10 egg yolk antibodies fed upon arrival to a calf ranch would lower the prevalence of Cryptosporidium parvum shedding in naturally challenged preweaned dairy calves. The secondary objectives included measuring the effect of anti-IL-10 antibodies on calf health, performance, and shedding of less common diarrheal pathogens. A total of 133 calves, enrolled at 24 to 72 h of age, received a daily dose of 0.96 g of egg yolk powder with anti-IL-10 antibodies (MAB, n = 71) or without anti-IL-10 antibodies (MEP, n = 62) split between 2 feedings for the first 11 d on feed at a calf ranch. Daily health evaluations were completed for 15 d after arrival and on d 56. Digital weights were collected at enrollment and d 56, and hipometer weights were collected at enrollment and d 7 and 56. Packed cell volume and serum total protein concentration were measured at enrollment and on d 7 and 14. Fecal pH was measured at enrollment and on d 5 and 14, and fecal pathogen (C. parvum, coronavirus, rotavirus, and Salmonella spp.) shedding was assessed at d 5 and 14. Continuous outcomes were compared between groups using a Student's t-test or Wilcoxon rank sum test. Fecal pathogen shedding at d 14, respiratory disease at d 56, and antibiotic usage were compared using relative risk (RR) and chi-squared test. Fecal pH (median and interquartile range) on d 14 was 6.65 (6.39-6.99) and 6.52 (5.97-6.81) for MAB and MEP, respectively. On d 56, the risk of respiratory disease was lower for MAB compared with MEP (RR = 0.40; confidence interval = 0.16-0.99). The risk for antibiotic treatment was lower for MAB-compared with MEP-treated calves (RR = 0.38; confidence interval = 0.17-0.88). The risk of shedding rotavirus was higher in MAB (RR = 1.38; confidence interval = 1.10-1.81) calves. After multivariable analyses, hipometer weights (least squares means ± standard error) were 1.7 ± 0.8 kg greater on d 56 in MAB compared with MEP; however, ADG was 0.04 ± 0.02 kg/d lower in MAB calves. Total health score, diarrhea days, average respiratory score, packed cell volume, and serum total protein were not affected by feeding anti-IL-10 egg antibodies. In summary, feeding anti-IL-10 antibodies was associated with increased fecal pH, reduced risk of respiratory disease later in the preweaning period, and decreased antibiotic usage despite higher rotavirus infection. These findings might be associated with improved mucosal immunity, enhanced host defenses, or reduced susceptibility and warrant further investigation.
