Our objective was to evaluate the efficacy of bovine rotavirus antigen-specific passive antibody for reducing the duration of diarrhea induced by oral challenge with bovine rotavirus in a neonatal calf model. The bovine rotavirus-specific passive antibodies were produced before the study by...

The objective of this randomized clinical trial was to determine if an intervention with colostrum replacer (CR; Premolac Plus, Zinpro; 125 g/d fed for 3 d) or a placebo milk replacer (Cows Match, Land O'Lakes Inc.; 125 g/d for 3 d) following a triggered alarm could ameliorate disease bouts in...

The objective was to determine relationships between protein and energy consumed from milk replacer and starter and calf growth and first-lactation production of Holstein heifer calves. Milk replacer and starter protein intake and metabolizable energy (ME) intake data were collected from 4,534...

The first studies concerning nutrient requirements for preweaned dairy calves were from the 1920s and 1930s; however, few studies were published in the following decades. We aimed to determine energy and protein requirements of preweaning Holstein and Holstein × Gyr dairy calves in a multistudy...

Providing adequate concentrations of AA in the prepartum diet is pivotal for the cow's health and performance. However, less is known about the potential in utero effects of particular AA on early-life performance of calves. This experiment was conducted to determine the effects on dairy calves...

The present study was conducted to find out the nutritional profile of the cow milk in comparison to sow milk for the development of milk replacer to early weaned piglets. Milk samples were collected from sow on 7th, 14th, 21st, 28th and 35th day of lactation and cow milk was collected randomly....

The aim of the study was to determine the effectiveness of the use of Calf Milk Replacers "Groulak" and "Formulak-16" compared to the traditional feeding scheme for youngsters. The research was carried out in the production conditions of LLC "Druzhba", Zheleznogorsk district of the Kursk region....

Objective: Our objective was to determine effects of 3 nutritional programs on growth of Holstein calves from birth to 20 wk of age. Materials and Methods: Calves (30 female, 45 male) were assigned at 3 d of age to 3 treatments in a randomized block design: (1) low (LOW) milk replacer (454 g/d,...

In the market conditions of dairy cattle breeding, the problem of increasing productivity comes to the fore of cost-effective milk production. As best practices and zootechnical studies show, the productivity of cows is already laid at the level of raising calves of the dairy period. The main feed...

Diarrhea is the primary cause of morbidity and mortality in dairy calves. Many cases of diarrhea in calves are treated with antimicrobials, increasing the risk of antimicrobial resistance, therefore, creating a need for alternative therapies. The objective of this study was to evaluate the effects...
