A systematic review of the literature was carried out to perform a meta-analysis to assess effects of age at weaning on the performance of piglets in the range of 14 to 42 days old. This step consisted in defining the…
Emerging bacterial resistance to antibiotics increases the need for effective alternatives to control intestinal inflammation and thus gut disorders in piglets. This study evaluated the effects of including Saccharomyces cerevisiae (strain 1026) and Saccharomyces boulardii (CNCM I-1079) as antibiotic alternatives…
The use of leguminous leaf meal as feed ingredients for pigs needs to be intensified and improved. Leguminous trees and shrubs are valuable sources of protein, amino acids, and dietary fibre for pigs. Leguminous leaf meals are abundant in the…
There are increasing concerns about the impact of agriculture and livestock production on the environment. In this the greenhouse gas emissions (GHG) from South African pigs, ostriches, horses, donkeys, mules and poultry were calculated, using 2010 production data on a…
The objective of the study was to estimate genetic and phenotypic parameters for sow productivity traits of South African Large White pigs, using data from the Integrated Registration and Genetic Information Systems. The analyses were done on 29 719 records…
Records kept over a 4-year period on a 300-sow Natal north coast farm show that reproductive efficiency in pigs is markedly depressed during the hottest months of the year. Under these conditions mean monthly temperatures in excess of 22 C…
A mathematical model together with data analyses were adapted to describe the effect of variation in dietary energy concentration, achieved by the inclusion of different levels of sawdust, on the growing pig. It was found that the autoregression coefficient of…
An experiment was conducted (1) to determine the effect of formaldehyde treatment on the protein digestibility, nitrogen retention and energy digestibility of birdproof grain sorghum, and (2) to evaluate the effect of treated grain, when used as a grain component…
This study was undertaken to investigate the suitability of various dissected carcass joints as predictors of total body fat in the carcass in order to minimize the time, labour and costs involved in carcass evaluation techniques. A total of 22…
This study was undertaken to investigate the suitability of various carcass fat measurements as predictors of total body fat in the pig in order to minimize the time, labour and costs involved in carcass evaluation techniques. A total of 33…
Five diets, containing equal amounts (23 %) of crude protein, and different energy concentrations, ranging from 11,5 to 17,0 MJ ME/kg DM, were fed ad lib to 52 Landrace X LargeWhite barrows. Dietary energy content was manipulated by replacing maize…
The influence of various factors on the occurrence of high ultimate pH values as an indication of dark, firm and dry (DFD) pork at a South African bacon factory. This survey was conducted to determine the occurrence of DFD meat…
Two experiments were conducted, (1) to determine the effect of the polyphenol content of sorghum on nitrogen and energy digestibility and (2)to compare a high polyphenol content class KF sorghum cultivar (BPS)and a low polyphenol content class KM cultivar (NS)…
The partial replacement of full-fat soyabean meal in diets for early-weaned pigs with algae or sunflower oil cake meal. Three starter diets for early-weaned pigs, (weaned at an age of 21 days) were fed ad libitum for 26 days to…
A digestion and a growth trial was conducted, (i) to determine the effect of sodium hydroxide (NaOH) treatment of bird-proof sorghum (BPS) on nitrogen and energy digestibility, and (ii) to compare treated with untreated BPS as grain components in a…
A nitrogen-balance study was carried out to investigate the utilization of various levels of urea (0 - 4%) absorbed by alkali-ionophore-treated whole maize when fed to Angora goats receiving a protein-deficient roughage diet. Nitrogen retention was increased significantly (P<0,05) only…
The evaluation of sewage sludge as protein source for growing pigs. The utilization of sewage sludge (28% CP) as a protein source in pig growth diets was investigated. Fish meal was replaced by sewage sludge at three levels (0%, 25%…
Two experiments were conducted to evaluate L. albus cv. Buttercup as an alternative to heated full-fat soya bean meal for early weaned piglets. In Experiment 1, the performance of piglets, fed diets with 0%, 4%,8% and 12% lupins and formulated…
A group of slow-growing Landrace and a group of fast-growing Large White boars were used to study their patterns of feed intake, growth rate and feed utilization. The pigs were fed ad libitum on a high-energy diet of a high…
