Genetic prediction models and heritability estimates for functional longevity in dairy cattle
(South African Society for Animal Science, 2015)
Longevity is a major component of the breeding objective for dairy cattle in many countries because of its high economic value. The trait has been recommended for inclusion in the breeding objective for dairy cattle in ...
The effect of Moringa oleifera leaf meal supplementation on tibia strength, morphology and inorganic content of broiler chickens
(South African Society for Animal Science, 2014-08-13)
This study was conducted to assess the effects of dietary Moringa oleifera leaf meal (MOLM) supplementation as a possible alternative to antibiotic growth promoters on bone breaking strength (BBS), tibia bone morphology ...
Non-genetic factors affecting fertility traits in South African Holstein cows
(South African Society for Animal Science, 2014-03-08)
Profitable milk production and genetic improvement in dairy herds depend largely on fertile cows calving annually to initiate a new lactation period. Over the last 30 years, several studies have indicated a decline in the ...
Potential of using maize cobs in pig diets : a review
(Asian-Australasian Association of Animal Production Societies, 2015)
The quest to broaden the narrow range of feed ingredients available to pig producers has prompted research on the use of low cost, unconventional feedstuffs, which are typically fibrous and abundant. Maize cobs, a by-product ...
Environmental and genetic factors affecting faecal worm egg counts in Merinos divergently selected for reproduction
(South African Society for Animal Science, 2015-12-09)
Infestation with gastrointestinal nematodes is probably among the most pervasive problems in small-stock production worldwide. Faecal worm egg count (FWEC) has been reported as an indirect measure of parasite resistance ...
Effects of whey, molasses and exogenous enzymes on the ensiling characteristics, nutrient composition and aerobic stability of maize cobs
(South African Society for Animal Science, 2016)
The study was conducted to assess the effects of whey, molasses and exogenous enzymes on fermentation, aerobic stability and nutrient composition of ensiled maize cobs. Five treatments were ensiled in 1.5 L anaerobic glass ...
