Abstract

SUMMARY This experiment was conducted to assess the palatability of the lesser known fodder trees such as calliandra, and albizia which may have potential to be included in farming systems in the tropics the experiment. It was conducted in The University of Queensland, Gatton College in 1996 using six sheep and six goats in a Latin Square design involving pair-wise comparisons of four types of fodder trees, calliandra, albizia, gliricidia and leucaena. Variables measured were intake rates of each of fodder tree examined and differences between means were examined by the general linear model procedure of the Statistical Analysis System. The results showed that the overall intake rate of tree leaves examined was affected by animal species (P<0.0017) and tree types (P< 0.001). Rates of intake of gliricidia were consistently low and those of leucaena were consistently high, by both species of animals. Goats ate more quickly overall than sheep, but both species ate gliricidia much less rapidly than the others. Rates of intake of both calliandra and albizia were altered by the type of leaf fed as the pair. Intakes of calliandra were faster when paired with gliricidia than with albizia, and were reduced further when paired with leucaena. Rates of albizia intake were similarly influenced by the fodder which was paired with it. Fodder trees can be ranked with increasing order of palatability such as gliricidia, calliandra, albizia and leucaena.

Abstract

ABSTRACT This experiment was conducted to assess the intake and digestibility of low quality rhodes grass (Chloris gayana) hay cv. Callide offered to sheep. Four rumen fistulated sheep were assigned to four dietary treatments with 21 days for each period namely, rhodes grass hay was fed alone ad lib. (treatment 1), rhodes grass hay was supplemented with 200 g/d oven-dried leucaena (treatment 2), rhodes grass hay was supplemented with 200 g/d leucaena plus 8 g/d urea (treatment 3) and rhodes grass hay was suplemented with 200 g/d leucaena plus 150 g/d sucrose (treatment 4). This experiment used a latin square design and variables measured were dry matter, organic matter intake and digestibilities of OM, NDF and N by the method of total collection, N balance, ruminal parameters such as rumen pH and ammonia, and rumen microbial protein synthesis. Differences between means were analysed by the General Linear Model procedure of the Statistical Analysis System. The results showed that although leucaena supplementation increased total DM intake total OM and digestible OM intake did not change. Supplementation increased ammonia-N concentration, N balance and efficiency of microbial N synthesis, especially with urea (P<0.05). It can be concluded that leucaena supplementation of 16% of DMI may need additional N source such as urea for better microbial N synthesis, however the need for ruminally fermentable organic matter may not be required unless rumen ammonia-N is not limiting.

Abstract

ABSTRACT Two trials were conducted to assess the effect of post-ingestive feed back of nutrients on intake of gliricidia leaves by sheep. In trial 1, six rumen fistulated sheep were used to compare four dietary treatments in a randomised complete block design. Gliricidia leaves were fed ad lib. with no other additives (treatment 1) or with 15 mg metoclopramide/kg body weight (treatment 2), or 0.5 % body weight of ground barley grain (treatment 3), or 0.5% body weight of cottonseed meal (treatment 4) administered into the rumen within 30 minutes before feeding the leaf. In trial 2, the same sheep as in trial 1 were used to compare four dietary treatments in a randomised complete block design. Gliricidia leaves were fed ad lib. (treatment 1), or with 0.5% body weight of cottonseed meal either administered into the rumen before feeding the leaf (treatment 2), or mixed with the leaf (treatment 3), or fed separately prior to offering the leaf (treatment 4). The results showed that administration of cottonseed meal into the rumen in trial 1 increased significantly daily intake of gliricidia leaves compared to the control treatment, or to administration of metoclopramide into the rumen (285 g vs. 171 g vs. 142 g) dry matter. However, administration of ground barley grain into the rumen did not significantly differ from any other treatment. In addition, none of dietary manipulations in trial 2 increased intake of gliricidia leaves by the sheep.

Abstract

SUMMARY Three trials were conducted to investigate the intake of oven-dried gliricidia by sheep, namely trial 1, addition of polyethylene glycol (PEG), trial 2, pretreatments, and trial 3 addition of additives. In the first trial, six rumen fistulated sheep were used to compare two dietary treatments in a change over design to study whether infusion of polyethelene glycol (PEG) into the rumen might increase intakes of gliricidia leaf as tannin in the leaf was believed to limit its intake. In the second trial, four sheep were used to compare four dietary treatments in a latin square design to study whether reheating or freezing the already oven-dried gliricidia leaf might increase its intake by the animals. On the other hand, the third trial was aimed to supplement the sheep with various supplements which are believed to be able to increase the taste of the leaf by the animals. These supplements were wheat millrun, molases, grass hay, cottonseed meal, palm kernel meal, or barley grain. For this reason, ten sheep were used to compare seven dietary treatments in a randomised complete block design. Differences between means were examined by analysis of variance using the General Linear Model procedure of the Statistical Analysis System. The results showed that neither administration of PEG into the rumen nor pretreatments (reheating or freezing) increased intake of gliricidia leaf by sheep. However, only mixing gliricidia with molasses increased the intake of the leaf by sheep over the control diet (gliricidia alone) over the six hours feeding period (43 vs 74 g DM).
