A simulation study was done to estimate the methane intensity and blue water footprint of a weaner calf production system in South Africa. Nine genotypes, representative of indigenous, British, Zebu, and European breeds, were chosen based on their relative numbers…
This study aimed to determine the effects of the addition of wood vinegar (WV) to drinking water on the production performance, intestinal histomorphology, and immune response of broiler chickens. In total, 432 one-day-old chicks were allocated to six groups (T1–T6),…
Naringin is an important flavonoid found in the fruit or peels of fruit from species of the Rutaceae family, such as grapefruit. The aim of this study was to investigate the effects of in ovo naringin injection on hatchability, hatchling…
This study aims to bridge the gap between the large stock unit method and the grazer and browser unit methods for estimating the stocking densities of wild herbivore ungulates on wildlife ranches and reserves using both extensive and intensive production…
The growing threat of antibiotic resistance necessitates the development of novel methods for addressing health management in animal production and reducing dependency on antibiotics. Biosecurity is a term that describes the various measures taken to reduce the introduction or proliferation…
Ross 308 broiler chickens are raised specifically for meat production, as they are fast growing and can be slaughtered at six weeks of age. This study aimed to use multivariate adaptive regression splines (MARS) and classification and regression tree (CART)…
The morphometric and type traits of 269 Dohne Merino ram lambs were measured and/or assessed at four, eight, and 12 months of age. Body conformation scores were also awarded independently by three judges at each age. Estimated phenotypic correlations between…
Articles (1558 in total) published in the South African Journal of Animal Science (SAJAS) were identified in the Scopus, Scielo, and InCites (Web of Science) databases. The Scimago Journal Rank (SJR) indicator for SAJAS in 2022 was 0.33, with a…
The fleeces of mammals with dense coats, such as the mohair fleeces of Angora goats, usually include medullated fibres. These fibres constitute a problem for the textile industry because of their structural characteristics. Three experiments were conducted in this study,…
This study aimed to evaluate the effects of dietary prickly pear (Opuntia ficus-indica) powder and Lactobacillus supplements on calf growth and faecal pathogen counts. Prickly pear leaves were harvested, sun-dried for 14 days, and oven-dried at 105 °C, before grinding…
This study characterised four naked neck chicken phenotypes (black, white-and-black, light brown, and dark brown) at 20 weeks of age, based on both qualitative and quantitative traits. A total of 320 birds were evaluated, with 40 males and 40 females…
This meta-analysis aimed to identify the optimal inclusion and threshold levels for black wattle, quebracho, and chestnut tannin extracts (TE) in sheep and cattle, in terms of their effects on dry matter intake (DMI), digestibility, weight gain, and nitrogen balance…
This study assessed the effects of supplementing organic chromium (Cr), alone and in combination with propylene glycol (PG), on milk yield and blood chemistry in early lactation dairy cows. Thirty multiparous Holstein cows were randomly assigned to three treatments: control…
The article ‘Effects of rumen undegradable protein source on feed intake and milk yield of Holstein dairy cows’ (SAJAS volume 53, issue 5, DOI: 10.4314/sajas.v53i5.15) was initially published with an incorrect author list. The correct author list is as follows:…
The main objective of this study was to develop and validate a high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) method for the determination and quantification of three metabolites in raw milk samples: creatinine, citrate, and β-hydroxybutyrate (3-BHB). The effect of the…
Routine husbandry procedures for lambs are increasingly scrutinised for their animal welfare implications. One such procedure is tail-docking, which is commonly performed to prevent breech blowfly strike. Although tail-docking is considered painful for lambs, the precise level of pain remains…
This study was conducted to investigate the effects of monochromatic light on the growth performance, muscle development, and blood parameters of goslings from one to 14 days of age. A total of 192 male Sichuan White goslings were randomly assigned…
The article ‘PCV2: The unexpected threat - How fish infection can transform industries and society: A pilot study’ (SAJAS volume 54, issue 1, DOI: 10.4314/sajas.v54i1.11) was initially published with an incorrect author list. The correct author list is as follows: D.F…
There is considerable pressure to eliminate the use of conventional cages in commercial layer hen production systems. However, the assessment of alternative systems that can ensure the hen's ability to perform natural behaviours, while simultaneously enhancing farm productivity and economic…
This study investigated the effects of incremental increases in acid detergent fibre (ADF) content on the nutrient digestibility and performance of South African Mutton Merino wether lambs fed low-fibre finishing diets. Four dietary treatments were formulated with similar nutritional compositions,…
