Abstract:

Growth and metabolic studies were conducted with 32 sheep (16 rams and 16 ewes) to evaluate Ficus leaves (Ficus thonningia) as substitute for Hyparrhenia rufa (Hyparrhenia) in the diets of sheep. Ficus replaced 0, 25, 50 and 75% of grass and was offered at 3% of animal body weight as DM. all the sheep received concentrate at 1% of body weight as supplement. Digestibilities of DM, NDF, ADF and N were similar (P > 0.05)lower. Nitrogen retention was positive and the values increased with dietary level of Ficus up to 50% and then declined.

SUMMARYVarious physiological characteristics of castrate male sheep fed ad libitum were studied between 1986 and 1987 in Australia. The sheep were between 20 and 45 kg live weight (LW) before and during fattening. Sequential data on body composition, estimated from TOH space (starting at 10 kg), established that the weight gain contained 19% fat and 13% protein below c. 26 kg LW and 55% fat and 10% protein above. For a given feed intake, the rate of fat gain was constant but the rate of body protein gain was 45% lower above 26 kg LW. Voluntary feed consumption per unit weight peaked at 26 kg L

Abstract:

The cost of feed is the highest expenditure on animal husbandry management. One solution to reduce the high cost of feed is by utilizing local feed ingredients or abundant horticulture waste. Waste from bananas namely banana peel can be used as small ruminant animal feed so that feed efficiency can be achieved both in terms of cost, nutrition and feed formulation. Abundant banana skin waste that has not been used optimally so that it is feared can cause environmental pollution. To prevent the accumulation of horticultural waste, one of which is by giving cattle as feed used in the dry season.

Abstract Winter feeds costs for small ruminants exceeds 50% of the total cost of most small ruminant production systems in the Southeastern U.S. Keeping these feed costs low is one of the most effective and time-tested ways to improve farm profitability. While maintaining an appropriate stocking rate will be critical for sustaining long-term farm productivity, a suite of other management practices is available to assist in this objective. Installing appropriate fence and watering system infrastructure for managing grazing will be critical for improving harvest efficiency and stockpiling forage

Precision chopped (PC) and round bale (RB) silages were made from wilted forage that had been cut either with a regular mower conditioner (CON) or a mower macerator (MAC). Silages were fed to growing steers in a 10-wk feeding trial using a 2 × 2 factorial design. To determine apparent digestibility, silages were fed to wether sheep and ruminally incubated in nylon bags using two canulated cows. The DM concentration of silages ranged between 273 and 362 g kg−

Abstract United States seedstock sheep producers have selected sheep for higher weaning and post-weaning weights using estimated breeding values for approximately forty years. Despite this, little work has investigated if the increased performance has inadvertently resulted in increased feed intakes, increasing total feed costs for the producer. Eighty range-breed ewe lambs (forty Targhee and forty Rambouillet) were enrolled in a residual feed intake (RFI) trial shortly after weaning at approximately four months of age.

AbstractIncluding feed efficiency as a trait for selection has gained interest in the sheep industry because it can result in reduced feed inputs or improve stocking rates, both of which translate into increased profitability for the producer. It is of interest whether the feed efficiency status of a testing population of sheep could be predicted using rumen microbial profiles associated with divergent feed efficiency status in a training population of sheep. Two populations of ewes were fed the same diet, and each group was evaluated for feed efficiency. A total of 20 animals in the testing p

Under the given economic conditions, a higher processing price of feed may be expected in cattle fattening. Thus, from the economic standpoint farm
