this study was performed to determine the effect of injecting selenium into pregnant heifers at the last stage of gestation on the serum se, cu, zn and fe status of the heifers and their calves. fifty holstein heifers were randomly assigned to one of five treatments. four and two weeks before the expected time of calving, the heifers were injected intramuscularly 10 ml (t1), 20 ml (t2), 30 ml (...

After a milk meal, bucket-fed calves show non-nutritive oral activities, including cross-sucking, and this can discourage producers from rearing them in groups. Sucking is known to induce a quiet state in humans and rats. We examined if nutritive sucking affects non-nutritive oral activities in calves, if it reduces arousal (assessed through behavior and cardiac activity), and if sucking a dry ...

The aim of this work was to study the possibility of using a new commercial polyester/cotton fabric to repair large sized umbilical and abdominal hernias in calves and small ruminants. Twenty-four animals (16 calves, 3 buffalo calves, 4 sheep, 1 goat) with umbilical or abdominal hernia were included in this study. The diameter of hernial ring ranged from (12-25) cm. An underlay technique was us...

Probiotics are a promising alternative to improve food animal productivity and health. However, scientific evidence that specific microbes can be used to benefit animal health and performance is limited. The objective of this study was to evaluate the effects of administering a live culture of Faecalibacterium prausnitzii to newborn dairy calves on subsequent growth, health, and fecal microbiom...

To observe the effects of supplemental dietary d-α-tocopherol in relation to dietary energy on growth and immune status in dairy calves, 32 newborn Holstein bull calves were assigned to 1 of 4 treatments for 5 wk in a 2 × 2 factorial, randomized complete block, split-plot design. Calves received moderate growth (MG) or low growth (LG) all-milk dietary treatments, formulated to support daily gai...

Accepted: 01/05/2015 Abstract Group A rotaviruses play an important role in causing gastroenteritis and mortality in buffalo calves. To investigate the epidemical characteristics and prevalence of bovine rotavirus (Group A rotavirus) in Punjab, 120 fecal samples were collected from buffalo calves (n=93) and cow calves (n=27) up to 3 months age group calves exhibiting diarrhoea during the period...

Two receiving and two finishing trials evaluated energy source and escape protein supplementation for calves. In receiving Trial 1, 398 calves (257 +/- 24 kg BW) were used in a 2 x 2 factorial arrangement of treatments. Energy sources were dry-rolled corn (DRC) and wet corn gluten feed (WCGF); each was fed without or with supplemental escape protein (EP). Calves fed WCGF gained slower (P < .05)...

Beef production is an important development area in animal breeding with meat quality being determined by both paratypic and genetic factors. In this regard evaluating genetic material for the presence of desirable allele combinations of genes associated with growth and development indicators, as well as meat qualities of animals have a certain scientific and practical significance. The aim of ...

Various two-breed cross cow groups were mated to Charolais and Limousin bulls to produce a total of574 three-breed cross calves over a two-year period. Average birth weights were 81.2 Ib and 76.2 Ib for calves produced from Charolais and Limousin sires, respectively. Calving assistance was required for 12.4 percent ofCharolais-sired calves and 4.0 percent of the Limousin-sired calves. Charolais...
