Special Issue Information

Dear Colleagues,

We are pleased to announce that the Special Issue entitled “New Nutrition Strategies: Prenatal and Postnatal Growth in Livestock Animals” will compile innovative and outstanding research on animal growth processes and the effects of nutrition on it in production animals intended for human consumption.

Human beings have a specific demand for nutrients under essential phases of our lives, which largely come from terrestrial foods of animal origin. According to the FAO (2023), these foods provide 34% of good-quality protein and 17% of calories available for consumption, in addition to various minerals and vitamins, such as iron, zinc, selenium, vitamin B12, choline, and calcium, among others. Likewise, they also provide bioactive factors with functions in human health that are only found in this type of food, such as carnitine, creatine, taurine, hydroxyproline, and anserine. Also, the long-chain fatty acids and proportions of essential fatty acids found in these foods are important for cognitive function at all stages of people's lives.

Therefore, it is essential to develop new strategies based on scientific evidence that improve animal growth processes to supply enough meat for human consumption.

This Special Issue aims to inform the scientific community of recent research on the advances and innovations related to improving the efficiency of growth and nutrient utilization in animals, from the embryonic state to birth and finalization, with the aim of obtaining a greater quantity and quality of products of animal origin.

We invite you to send original manuscripts or reviews in fields related to the main topic of this Special Issue. Research areas may include (but are not limited to) the following:

  • Animal nutrition.
  • Growth physiology.
  • Nutrition and embryonic development.
  • Diets and ruminal microbiology.
  • Diets and nutrient absorption.
  • Growth stimulants.

We look forward to receiving your contributions.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Animals is an international peer-reviewed open access semimonthly journal published by MDPI.

Abstract
This study assessed the effects of different prepartum supplementation plans on Nellore cows’ performance, metabolic responses, and early offspring development. Thirty-nine pregnant Nellore cows (224 ± 2.67 days of pregnancy, 5.3 ± 0.29 years of age, body weight 520 ± 15.2 kg, initial [...] Read more.
This study assessed the effects of different prepartum supplementation plans on Nellore cows’ performance, metabolic responses, and early offspring development. Thirty-nine pregnant Nellore cows (224 ± 2.67 days of pregnancy, 5.3 ± 0.29 years of age, body weight 520 ± 15.2 kg, initial body condition score 6.0 ± 0.07) were assigned to one of four treatments: a control group receiving only mineral mixture ad libitum, and three groups receiving daily protein-energy supplements of 2, 4, or 6 g/kg BW for 60 days prepartum. Weights and body condition scores were evaluated at the start of the experiment, 7 days before calving, and at 45 and 90 days postpartum. Cows supplemented with 4 and 6 g/kg BW showed improved body weight and body condition scores prepartum and postpartum and had a shorter service period (p < 0.05). The highest blood urea nitrogen concentrations were observed in cows receiving 6 g/kg BW (p = 0.0124). There was a reduction in blood urea nitrogen at calving for the 6 g/kg BW group, while the control group showed an increase (p < 0.001). Non-esterified fatty acids concentrations were lower 21 days before calving for the 4 and 6 g/kg BW groups compared to the control (p < 0.05) and decreased postpartum for all treatments (p < 0.001). No significant differences were observed in calf birth weight or performance. Supplementing with 4 g/kg BW of protein-energy is recommended to enhance metabolic health and overall performance.
