Phenotypic and genetic relationships for feed intake, feed efficiency, body composition and cow milk yield measured postweaning and in mature beef cows Anim. Prod. Sci. (IF 1.4) Pub Date : 2023-08-22 J. A. Archer, A. Reverter, R. M. Herd, P. F. Arthur
Context: Providing feed is the largest cost in beef production. Genetic variation exists in feed efficiency traits in young cattle but the genetic associations with feed efficiency traits in cows are poorly understood, but if strong and favourable, they might be used to improve feed efficiency of cows. Aim: To examine the phenotypic and genetic relationships among feed intake, feed efficiency, body

Effects of dietary Sanguisorba minor, Plantago lanceolata, and Lotus corniculatus on urinary N excretion of dairy cows Anim. Prod. Sci. (IF 1.4) Pub Date : 2023-08-14 A. N. Kapp-Bitter, J. Berard, S. L. Amelchanka, C. Baki, C. Kunz, A. K. Steiner, M. Kreuzer, F. Leiber
Context: Mitigating urinary nitrogen (N) losses is an important target of sustainable cattle nutrition concepts. One option to achieve this may be dietary inclusion of tanniferous herbs. Aims: Aim of the study was to investigate herbs with different profiles of tannins for their efficiency to abate urinary N losses. Small burnet (Sanguisorba minor) with high concentrations of total tannins, plantain

Estimating potential farm economic benefits of advanced microbiological diagnostics in veterinary medicine Anim. Prod. Sci. (IF 1.4) Pub Date : 2023-08-14 Jørgen Dejgård Jensen, Tove Christensen, Potjamas Pansri, John Elmerdahl Olsen
Context: Intensive livestock production is challenged by frequent occurrence of contagious livestock diseases. Advanced diagnostic tools, such as quantitative polymerase chain reaction (qPCR), have been found to improve the precision and speed of veterinary diagnostics. Aims: This study develops and applies an analytical quantitative framework to investigate the potential farm economic benefits of

A regional-scale assessment of nutritional-system strategies for abatement of enteric methane from grazing livestock Anim. Prod. Sci. (IF 1.4) Pub Date : 2023-08-15 A. K. Almeida, F. C. Cowley, R. S. Hegarty
Progress towards methane (CH4) mitigation for the red meat, milk and wool sectors in Australia and reduced CH4 emissions intensity (g CH4/kg animal product, typically milk or liveweight gain) involves not only reduced net emissions but also improved productive efficiency. Although nutritional additives have potential to reduce CH4 production rate of livestock (g CH4/head.day), systemic improvement

Candidate genes for height measurements in Campolina horses Anim. Prod. Sci. (IF 1.4) Pub Date : 2023-08-10 Lisia Castro Krebs, Marina Monteiro de Moraes Santos, Maria Claudia Siqueira, Brennda Paula Gonçalves de Araujo, Iara Del Pilar Solar Diaz, Raphael Bermal Costa, Chiara Albano de Araújo Oliveira, Marina Mortati Dias Barbero, Gregório Miguel Ferreira de Camargo, Fernanda Nascimento de Godoi
Context: Genomic tools allow for increased efficiency in animal production and, consequently, greater production gains. Morphometric measurements of height can be used for breed characterisation/registration, and sex distinction, in addition to being associated with balance, posture, and the range of motion of the limbs, influencing the dynamics and quality of the gait. Aims: This study was conducted

Body temperature, heart rate, and locomotor activity measured by bio-loggers before and after a progestogen+eCG treatment for artificial insemination in sheep: effect of pregnancy Anim. Prod. Sci. (IF 1.4) Pub Date : 2023-08-07 J. A. Abecia, F. Canto, J. Plaza, C. Palacios
Context: The introduction of bio-sensors for monitoring real-time changes in physiological variables has helped understand how external factors affect an animal’s resiliency to stressors. Aims: To quantify changes in temperature, heart rate, and locomotor activity in ewes during hormonal treatments for artificial insemination (AI) for up to 15 days after insemination. Method: Twelve ewes received a

Effect of coated sodium butyrate in diet on performance, gut microbiota, ileal digestibility, serum nutrient fractions, immune responses and bone mineral variables in broiler chicken fed antibiotic-free diet Anim. Prod. Sci. (IF 1.4) Pub Date : 2023-08-03 Savaram V. Rama Rao, V. L. N. Raju Mantena, Shyam Sunder Paul, Nagalakshmi Devanaboyina, Srilatha Thota, Prakash Bhukya, Santosh Phani Kumar Prakki
Content: Antibiotic growth promoters (AGP) are not recommended in broiler diets due to the possible threat of microbial resistance and residues in meat. Aim: Two experiments were conducted to study the possibility of utilising coated sodium butyrate (CSB) as an alternative to AGP (500 g/t) in broiler (1–42 days) chicken diet. Method: In Experiment 1, a positive control (PC with AGP), a negative control

Energy intake and nutritional balance of roe deer (Capreolus capreolus) in special Bavarian landscapes in southern Germany Anim. Prod. Sci. (IF 1.4) Pub Date : 2023-07-31 Andreas König, Sarah-Alica Dahl, Wilhelm Windisch
Context: Irrespective of the fact that the European roe deer (Capreolus capreolus) occurs from the Mediterranean to north of the Arctic Circle and is one of the most abundant and widespread species, roe deer are fed in winter in Germany and Austria. Hunters justify the supplementary feeding with the argument that roe deer do not find sufficient high-quality food in our landscape and they would have

Effects of the organic selenium sources with/without probiotics on broiler chicken growth, meat quality and meat selenium content Anim. Prod. Sci. (IF 1.4) Pub Date : 2023-07-31 A. Shokrinejad Gerdin, M. Afsharmanesh, M. Salarmoini, M. Khajeh Bami
Context: Selenium is an essential trace micronutrient that plays an important biological role in maintenance of animal health. Aims: The purpose of this study was to compare the effects of dietary supplementation of selenium (Se)-enriched yeast (SeY), Se–chitosan (SeCh), and selenised glucose (SeGlu) as organic forms of Se, as well as the interaction of these compounds with probiotics, on broiler chicken

Relationship between carcase traits of Bos taurus genotypes and ultrasound measurements across six stages of growth from weaning through to long-feedlot finishing Anim. Prod. Sci. (IF 1.4) Pub Date : 2023-07-31 Tharcilla I. R. C. Alvarenga, Amelia K. Almeida, Malcolm McPhee, Jason P. Siddell, Brad Walmsley, Paul L. Greenwood, Matt L. Wolcott
Context: Identification earlier in life of beef cattle with capacity for increased marbling, improved carcase yield and/or reduced subcutaneous fatness can facilitate more rapid genetic improvement and identification of cattle more appropriate for feedlot or pasture finishing. Earlier in life, ultrasound predictions have potential for significant improvements in compliance with market specifications

Malnutrition of pregnant beef cows and the impact on passive immunity transfer to calves Anim. Prod. Sci. (IF 1.4) Pub Date : 2023-07-20 L. F. P. Silva, L. G. S. Coimbra, K. Eyre
Nutritional management in rangeland beef cattle systems prioritises optimal body condition scores at calving for improved fertility and reproductive success. However, this focus often overlooks short-term dietary deficiencies before calving, which can lead to adverse outcomes for neonatal calves. This review explores the effects of beef cow malnutrition during the periparturient period on colostrum
