In Exp. 3, the concentrations of α-Toc in colostrum were greater than those in precolostrum (samples were collected at wk -1 relative to parturition) and mature milk. The expression of TTPA, SEC14L2, and CYP4F2 mRNA in bovine mammary gland tissue was detected. However, TTPA and SEC14L2 mRNA expressio …

The effects of early weaning on innate immune responses of Holstein calves.

The objectives of this study were to compare innate immune responses of calves weaned early (EW; n=23; weaned at 23.7 ± 2.3 d of age) with those of conventionally weaned calves (CW; n=22; weaned at 44.7 ± 2.3 d of age). All calves were fed 3.8L of colostrum within 12h of birth and were subsequently fed milk replacer twice daily. The weaning process began by withdrawal of the afternoon milk-replacer feeding. Milk was fully withdrawn, and the calf was considered completely weaned when it consumed 900 g of calf starter as-fed for 2 consecutive days. Blood samples were collected from all calves at…

Effect of vitamin E sources (RRR- or all-rac-alpha-tocopheryl acetate) and levels on sow reproductive performance, serum, tissue, and milk alpha-tocopherol contents over a five-parity period, and the effects on the progeny.

Sow liver, adipose, lung, and heart alpha-tocopherol contents were also higher (P < .01) when the 60 IU vitamin E level had been fed. Both serum and liver a-tocopherol contents in 21-d- …

Cross-neutralization and antigenic characterization of simian and equine group A rotaviruses.

UNLABELLED: Rotaviral diarrhea in foals is caused by two dominant G3P[12] and G14P[12] genotypes of equine rotavirus A (ERVA). Protection of foals against ERVA infection and disease is achievable by passive antibody transfer through colostrum from mares receiving inactivated monovalent G3P[12] vaccine. Simian rotavirus SA11 G3P[2] is also included in ERVA vaccines to protect foals. Here, we characterized cross-neutralization and protection among three distinctive rotaviruses carrying the same or different G (defined by VP7) or P (defined by VP4) genotype by using a rabbit and equine monospecif…

Ovarian cancer in a former asbestos textile factory worker: a case report.

BACKGROUND: Prelacteal feeding is one of the major harmful newborn feeding practices and is top on the list of global public health concerns. The practice deprives newborns of valuable nutrients and protection of colostrum and exposes them to preventable morbidity and mortality. Studying the prevalence and factors influencing the prelacteal feeding practice of mothers will help program managers and implementers to properly address broad major public health problems. Therefore, this study aims to investigate the prevalence of prelacteal feeding practices and its associated factors among mother-…

Effect of serum calcium status at calving on survival, health, and performance of postpartum Holstein cows and calves under certified organic management.

The study objective was to assess the effect of hypocalcemia (HYPO; ≤2.0 mmol/L) of the dam at calving on survival, health, and performance of lactating dairy cows and their calves under certified organic management. Prepartum dairy cows (primiparous, n = 445; multiparous, n = 328) from 1 dairy herd were monitored (prepartum pen) for imminent signs of parturition (appearance of amniotic sac outside the vulva) until birth. All calves were subject to the same newborn care, colostrum management, and failure of passive transfer assessment (serum total protein ≤5.5 mg/dL). Serum total calcium of co…

Узкие полифенолы в питании свиноматок: обновление.

Окисляющий стресс является потенциально критическим фактором, влияющим на производительность гектарирующих и кормящих свиней. Полифенолы представляют собой большой класс вторичных метаболитов растений, обладающих мощными антиоксидантами. Все полифенолы структурно характеризуются ароматическими кольцами с множеством гидроксилов водорода; они делают полифенолы идеальными атомами водорода и электронными донорами для нейтрализации свободных радикалов и других реактивных видов кислорода. В течение последнего десятилетия все большее внимание уделялось полифенолам в качестве функциональных кормовых д

Engineering the transmissible gastroenteritis virus genome as an expression vector inducing lactogenic immunity.

The genome of the coronavirus transmissible gastroenteritis virus (TGEV) has been engineered as an expression vector with an infectious cDNA. The vector led to the efficient (>40 micro g/10(6) cells) and stable (>20 passages) expression of a heterologous gene (green fluorescent protein [GFP]), driven by the transcription-regulating sequences (TRS) of open reading frame (ORF) 3a inserted in the site previously occupied by the nonessential ORFs 3a and 3b. Expression levels driven by this TRS were higher than those of an expression cassette under the control of regulating sequences engineered wit
