This study assessed the seasonal availability and nutrient profiles of pig feedstuffs present on small-scale farms in the Cape Metropole, South Africa. Eighty-two feedstuffs (54 in winter and 28 in summer) were collected from 50 small-scale urban pig farms in…
This study aimed to evaluate the effect of gonadotropin-releasing hormone (GnRH) administration 48 hours after progesterone-impregnated sponge removal on fertility and prolificacy in lactating Assaf ewes. In this study, 71 ewes were synchronised using intravaginal sponges containing 60 mg medroxyprogesterone…
This study aimed to develop and characterise a fish burger made from mechanically separated tambaqui (Colossoma macropomum) meat and incorporating soy okara as a functional ingredient. Four fish burger formulations were developed and the physicochemical characteristics (moisture, ash, lipid, protein,…
The aim of this research was to investigate the effects of different feeding regimes on the growth performance, nutrient intake, apparent digestibility, and ruminal metabolic and morphological characteristics of Awassi lambs. A total of 96 lambs (initial age: 10 ±…
This study investigated the effects of supplementing vitamins and minerals to sows during early gestation. A total of 36 primiparous sows were randomly assigned one day before mating to four dietary treatments that were applied from mating to day 30…
Free-ranging wild herbivores in Africa comprise 78 species of ruminants and several species of monogastric hindgut fermenters, and are classified as grazers, mixed feeders, and browsers. The objective of this review is to provide guidance to wildlife nutrition advisers by…
With climate change and its associated impacts on weather patterns being an inescapable reality, livestock producers will have to explore management and mitigation strategies to maintain production levels under adverse weather conditions. It is well-documented that ewe age affects reproductive…
South Africa has a long history of studying specific dietary deficiencies in livestock grazing natural pastures (veld), with these pastures generally regarded as deficient in protein and phosphorus. The pioneering work by Sir Arnold Theiler and co-workers focused on addressing…
The article ‘Assessing parallel testing to improve detection of bovine tuberculosis at a slaughterhouse in Lahore, Pakistan’ (SAJAS volume 54, issue 4, DOI: http://dx.doi.org/10.4314/sajas.v54i4.02) was initially published with an error in the second paragraph of page 497. This correction is…
Artificial lighting has enabled improvements in egg production, and different types of light and wavelengths have been tested to achieve better production results in the past. It has been established that red light positively affects the laying performance of hens…
This study investigated the effects of incremental levels of polyethylene glycol (PEG) treatment on the chemical composition and in vitro dry matter degradability (IVDMD) of Searsia lancea leaves. Polyethylene glycol was sprayed onto S. lancea leaves at 0, 5, 10,…
Fertility management of extensively farmed beef cattle in South Africa is essential to ensure the economic viability of such production systems. However, the success of timed artificial insemination (TAI) programmes varies, affecting cattle farmers' adoption of this reproductive technique. This…
The performance and health status of dairy calves may benefit from further transition milk feeding during the early postnatal period. However, transition milk obtained from cows during the first three to seven postpartum milkings is usually commingled with bulk tank…
This study evaluated the effects of oral propolis supplementation on haematological and metabolic indicators and coagulation parameters in neonatal lambs. Forty healthy newborn lambs were randomly assigned to either a control group or a treatment group receiving 1.5 mL of…
Neem products are biologically and pharmacologically active and could therefore serve as alternatives to antibiotics in pig feed. This study evaluated the effects of adding ground neem seeds (GNS) to the diets of fattening pigs on growth performance, carcass characteristics,…
Pigs need a balanced diet for optimum physiology. We therefore investigated the nutritional composition of variably sourced swill fed to free-roaming pigs in Gert Sibande District Municipality, South Africa. Fourteen swill samples, originating from households, schools, restaurants, and wholesalers, were…
This study investigated the effects of grapefruit juice supplementation on the performance, egg quality, and blood biochemistry of late-phase laying hens. A total of 144 Babcock White laying hens, aged 62 weeks and weighing 1603.05 ± 14.33 g, were divided…
The aim of this study was to assess the quality of ground maize grain silage rehydrated with varying proportions of whey, in comparison with silage rehydrated with water, to determine the potential of using whey during silage production as a…
In Limpopo Province, South Africa, livestock commonly graze freely around wastewater treatment plants (WWTPs), raising contamination concerns and prompting the assessment of heavy metal levels in palatable grasses, sludge liquors, and cow faeces. Twenty-one cow faecal samples were collected from…
In order to create a selection programme aimed at improving the production characteristics of rainbow trout, broodstocks from eight fish farms in the Republic of Serbia were collected in 2010. The spawning of broodstocks, hatching of eggs, and rearing of…
