The objective of this study was to evaluate the effect of dietary fibre sources on the performance, carcass characteristics, and muscle fatty acid composition of finishing lambs. Fifty-eight Merino ram lambs were randomly allocated to nutritionally similar treatment diets differing…
This study evaluated the ingestive behaviour and performance of feedlot lambs fed saccharine sorghum and corn silages. Ten animals were randomly selected from a group of 32 uncastrated male Suffolk lambs. The four treatments consisted of diets with 50% of…
The objective of this research was to investigate and compare the quality of apple pomace silage ensiled with corn plant, sugar beet pulp, and pumpkin pulp for nutrient compositions. Fresh samples of apple pomace, corn plant, sugar beet pulp, pumpkin…
The influence of lucerne hay quality on the milk production potential and milk composition of Jersey cows was investigated. Three different grades of lucerne hay (Prime, Grade 1, Grade 2; selected according to the New Lucerne Quality Index) were included…
An investigation was conducted into the effects of sodium hydroxide treated maize straw on the water intake of milch goats when fed alone or in a complete mixed diet. Dry matter intake was more closely related to water intake than…
It has been postulated that intake of feed mixtures will increase with increasing levels of concentrate until a peak is reached, whereafter it will decline again due to a lack of roughage to ensure a healthy rumen environment. Thus, it…
Growth of beef bulls has been studied with the aid of the three genotypes, the Afrikaner, Hereford and Simmentaler. The study ranged from birth to about 80 weeks of age. Half of the bull calves were raised on a concentrate…
The effect of roughages on the retention time of concentrates in the rumen was studied in cattle and sheep fed diets with different concentrate:roughage ratios. The organic matter retention times were calculated from the ratio, OM content in the rumen/mean…
Four rumen-cannulated steers were fed a diet consisting of whole maize grain, high protein concentrate and molasses. Two of the four animals received 10% ground Eragrostis curvula hay in addition to the whole maize grain diet. The feeding period was…
The effect of starch fermentation in the rumen on the kinetics of roughage digestion, was studied using 12 sheep fed three roughages, viz. lucerne hay, maize cob leaves and wheat straw. The amount of starch infused per day was increased…
