Recent populations of the red sunflower seed weevil, Smicronyx fulvus LeConte (Coleoptera: Curculionidae), have been inconsistent or declining, particularly in North Dakota. Consequently, research on weevil biology, including development of resistant germplasm, has been limited. To determine whether cold storage of diapausing larvae could be improved, nonconstant temperature treatments (fluctua...

Abstract This experiment evaluated the effects of multiple bovine appeasing substance administration during a 42-day preconditioning program followed by feedlot receiving period on productivity, health, and physiological variables feeder cattle. Ninety recently weaned calves were obtained from Red Bluff Ranch (Norris, MT). All weighed (prior to transport). Calves loaded into livestock trailer, ...

Heat stress (HT) and photoperiod affect milk production and immune status of dairy cows. The objective was to evaluate the effects of HT abatement prepartum under controlled photoperiod on hepatic metabolic gene expression and cellular immune function of periparturient Holstein cows (n=21). Cows were dried off 46 d before expected calving date and assigned to treatments by mature equivalent mil...

1. The effect of fortification of food with iron to provide 10 mg elemental Fe/child per d was studied in preschool children maintained on a cereal diet, over a 5-month period. 2. The absorption of 5 mg Fe as ferrous sulphate mixed in one meal was 3.3% of the test dose and when 3.3 mg was given with each of three meals over a 2 d period the corresponding value was 4.8%. 3. The mean absorption o...

The effect of a Mg-deficient diet (200 mg Mg/kg feed) on the bioavailability of dietary Zn and the concentration of this cation in plasma, whole blood, skeletal muscle, kidney, heart and brain of Wistar rats was studied after 7, 35, 42, 49, 56, 63 and 70 d. Mg deficiency significantly decreased Zn in whole blood on day 42 of the experiment, but there was no significant change in plasma Zn throu...

1. Forty-eight intact male lambs (30 kg) were fed to gain 16 (H), 5 (M) or -6 (L) kg during a 42 d interval (period 1). Lambs from each of the H and M groups were fed to gain either 16 (HH, MH), 5 (HM, MM) or -6 (HL, ML) kg and lambs from the L group were fed to gain 27 (LS), 16 (LH) or 5 (LM) kg during the ensuing 42 d (period 2). 2. Fasting heat production (FHP) of four lambs from each treatm...

Two experiments were conducted to evaluate the effect of testosterone on growth and composition of cattle. In the first experiment, crossbred yearling heifers (n = 48) were assigned to four treatments: 1) control (no implant), 2) Synovex-H implants on d 1 and 84, 3) one testosterone propionate implant administered on d 1 and a second on d 84 and 4) two testosterone propionate implants administe...

Aim: We aimed to evaluate the relationship between subjective and objective refractive error measurement difference myopia progression in this study.
 Material Method: Children 6-18 year-old at beginning of follow-up period having who were followed up regularly every six months for a total least 36 included study. All children underwent detailed ophthalmologic examination. An autorefractor...

Data were obtained from an ongoing experiment involving divergent selection for blood serum IGF-I concentration in purebred Angus cattle. The experiment includes approximately 100 spring-calving (50 high and 50 low line) and 100 fall-calving (50 high and 50 low line) cows. The selection criterion is the mean of IGF-I concentrations measured on each animal at d 28, 42, and 56 of the postweaning ...
