Effect of harvesting frequency, variety and leaf maturity on nutrient composition, hydrogen cyanide content and cassava foliage yield.

The experiment studied the effect of harvesting frequencies and varieties on yield, chemical composition and hydrogen cyanide content in cassava foliage. Foliage from three cassava varieties, K94 (very bitter), K98-7 (medium bitter) and a local (sweet), were harvested in three different cutting cycles, at 3, 6 and 9 months; 6 and 9 months and 9 months after planting, in a 2-yr experiment carried out in Hanoi, Vietnam. Increasing the harvesting frequency increased dry matter (DM) and crude protein (CP) production in cassava foliage.

Chemical composition, digestibility, and voluntary feed intake of mango residues by sheep.

The chemical composition, digestibility, and voluntary feed intake by sheep of mango by-products were studied in an experiment with five dietary treatments consisting of mango peels and seed kernels, offered individually or together with urea block and a control. The mango residues were offered with rice straw and the control diet was straw only. Five groups of five male sheep of Djallonké type, 12-18 months old and weighing on average 18.

Effect of feeding different levels of foliage from Erythrina variegata on the performance of growing goats.

The effect of feeding different levels of foliage from Erythrina variegata on the performance of growing goats was studied using a local breed (Ma T'ou) with an average initial body weight of 11.2 kg (SD = 0.9).

Effect of adaptation strategies when feeding fresh cassava foliage on intake and physiological responses of lambs.

The objective of the experiment was to study different adaptation strategies to avoid HCN intoxication when feeding fresh cassava foliage to sheep. Twenty-four Phan Rang lambs (initial weight = 19.6 kg at 5.

Effect of feeding some West African browse foliages on growth and carcass composition in sheep.

The effect of feeding foliage from Afzelia africana, Pterocarpus erinaceus or Khaya senegalensis on growth performance was evaluated using 32 West African Djallonké rams of about 8 months of age and with a mean initial body weight (BW) of 16.1 kg. The animals were randomly assigned to four groups of 8 animals and the experiment lasted for 13 weeks.

Effect of suckling period on calf growth and milk yield of Zebu cows.

Eighteen multiparous Zebu cows in their third lactation and their calves were randomly allocated to three suckling periods, up to 3, 4 or 5 months of age of the calf. The cows were individually fed natural hay, cottonseed cake and molasses. At 2 months of age, all calves were separated from their mothers, and were offered cottonseed cake mixed with molasses and Mucuna hay individually.

Intake and digestibility in sheep and chemical composition during different seasons of some West African browse species.

Foliage of Afzelia africana, Pterocarpus erinaceus and Khaya senegalensis, from 10 trees per species, was collected every two weeks during the late dry, rainy and cool season to determine the seasonal effects on chemical composition. Fifteen rams of the Djallonké breed, weighing on average 20.0 kg, were used to evaluate the voluntary intake and digestibility of hay of A.

The effects of short-term feeding of fresh cassava (Manihot esculenta) foliage on gastrointestinal nematode parasite infections in goats in Cambodia.

The antiparasitic effect of cassava (Manihot esculenta Crantz) was tested in goats artificially infected with gastrointestinal parasitic nematodes. Each experimental group consisted of 6 pen-fed goats kept on a slatted floor. The treatments compared were: 1) controls fed grass only, 2) cassava replaced grass for 3 weeks from the commencement of larval dosing period, and 3) cassava replaced grass for 3 weeks after the worm infection was patent.
