Hepatic and haemato-biochemical alterations in juvenile Mozambique tilapia (oreochromis mossambicus) on pawpaw (carica papaya) seed meal
(Canadian Center of Science and Education, 2019-06-15)Pawpaw seed meal (PSM) can be used as an antifertility agent in animals, however there is no information on its potential toxicological effect on Mozambique tilapia (O. mossambicus). In this study the effect of PSM on the ... -
Hormonal profile and reproductive parameters of pre-vitellogenic mozambique tilapia (oreochromis mossambicus) on pawpaw (carica papaya) seed meal
(Canadian Center of Science and Education, 2019-06-15)The use of phytochemicals to control precocious maturation and indiscriminate spawning among tilapia species is an important issue in aquaculture. This study investigated the influence of pawpaw (Carica papaya) seed meal ... -
Effect of late prepartum fibre-based diets on the live weight changes and reproduction of Holstein cows in the subsequent lactation period
(South African Society for Animal Science, 2019-03-07)The objective of this study was to evaluate two late prepartum fibre-based diets that differed in nonstructural carbohydrate (NFC) and protein levels on live weight (LW) changes and fertility traits of Holstein cows until ... -
Growth, carcass and meat quality traits of two South African meat rabbit breeds
(South African Society for Animal Science, 2019-10-01)Rabbits could contribute to meat production in South Africa. However, little research has been done on rabbit farming in the country, including on the performance of locally available meat breeds. This study examined the ... -
Carcass and meat quality attributes of Malawi Zebu steers fed Vachellia polyacantha leaves or Adansonia digitata seed as alternative protein sources to Glycine max
(South African Society for Animal Science, 2019-05-09)To enhance smallholder beef farmers' capacity to cope with animal feed shortages, especially dietary protein induced by climate change, it is important to evaluate the feeding value of low-cost protein sources naturally ... -
Effect of varying levels of protein concentration on production traits of ostriches (Struthio camelus var. domesticus)
(South African Society for Animal Science, 2019-07-28)The ostrich industry is poised to recover from the recent lifting of the four-year export ban on fresh meat products to the European Union EU). However, during this period profit margins were severely affected and the need ... -
Effects of varying sweet lupin dietary inclusion levels on feather classes, leather traits and meat composition of feedlot ostriches
(South African Society for Animal Science, 2017-12-01)The main consumer products derived from ostriches are feathers, leather and meat. Despite progress in optimizing production practices, additional information is still necessary about the value of various raw materials as ... -
