“…The significantly lower intake in the G. sepium supplementation compared to that of M. oleifera could be due to palatability problem encountered by small ruminants when fed with G. sepium (25). The higher VFI in M. oleifera and G. sepium fodder combination supplement than the single supplement of M. oleifera and G. sepium is in line with the reports of other authors who asserted that there were better production outcomes in browse mixtures than single browses (9,26). This could be as a result of improved palatability due to the combination of the two fodders.…”

Moringa oleifera (Mo) and Gliricidia sepium (Gs) fodders and their mixtures were fed as protein supplements to basal diets of Panicum maximum (Pm) and cassava peels. Thirty two (32) yearling West African Dwarf (WAD) rams were divided into four groups of eight animals balanced for body weight and allocated to dietary treatments in a Completely Randomized Design for fifteen (15) weeks. Animals in group 1 consumed the basal diet only while animals from group 2, 3 and 4 were fed basal diets with supplements of Mo, Gs and their mixtures respectively. Voluntary feed intake (VFI), nutrient digestibility and nitrogen utilization of the animals were evaluated. Animals fed basal diet only had reduced VFI (252.36±22.0g day-1) while those on Mo and Gs mixtures had significantly higher (p<0.05) VFI value of 344.96±22.2g day-1. Voluntary feed intake of basal diet was increased significantly (p<0.05) for animals in group 2 and 4 (260.20±30.00 and 270.46±20.6g day-1 respectively). Higher but significantly different (p<0.05) dry matter digestibility values of 63.90±3.06, 62.72±3.02 and 68.50±4.32% were obtained for animals in group 2, 3 and 4 respectively while the animals in group 1 had the least value of 48.39±2.03%. Similar trend exist in crude protein and crude fibre digestibility with animals in group 4 having significantly higher (p<0.05) values of 60.62±5.24 and 68.63±3.22% respectively. The result of nitrogen utilization indicate significantly lowest (p<0.05) value of 3.56±0.16g day-1 of digested nitrogen for animals in group 1. Higher nitrogen retention value (p<0.05) of 65.81±4.20% was obtained in sheep on Mo and Gs fodder combinations. Those on separate Mo and Gs fodders were statistically similar (58.55±3.02% and 58.00±5.30% respectively) but higher (p<0.05) than those on basal diet (43.70±3.02%). Supplementation of Panicum maximum and cassava peels basal diet with Moringa oleifera or Gliricidia sepium fodders improved the intake of basal diet and enhanced better nutrient utilization of WAD sheep. Mixtures of the two fodders in the same ratio were superior to either supplementation.

“…High responses of these mixtures have been reported for small ruminants. For example, Bosman et al fed West African Dwarf (WAD) goats with gliricidia and leucaena as mixture (9). Weight gain with gliricidia alone was 2g/W -0.75 /day and for the mixture a weight gain of 8.2g/W -0.75 /day was obtained.…”

“…In this experiment, the amount of refusal of straw and enset leaf was high almost about 50% at higher offer rate. Bosman et al (1995) suggested that if the feed is heterogeneous and thus offers opportunity for selection, high offer levels and accompanying high refusal rates may have to be accepted if the objective is to maximize animal production per unit of available feed. Wahed et al (1990) demonstrated that increasing the amount of barley straw by allowing higher refusal rates (above 50%) than the conventional 10-20% refusal rate enhanced voluntary intake in sheep and goats.…”

“…Entretanto, seria arriscado descartar técnicas como a amonização, uma vez que o efeito de níveis de oferta não tem sido estudado com palhas tratadas. Outro aspecto importante a ser considerado é que, para caracterizar o valor nutritivo da palha amonizada, necessita-se de informações sobre o consumo potencial máximo, a digestibilidade da matéria seca (MS) e o balanço de nitrogênio em condições nas quais é permitido ao animal ampla oportunidade para selecionar o alimento (BOSMAN et al, 1995). BOSMAN et al (1995) sugerem que uma forma de medir o valor do alimento para produção animal é determinar a quantidade máxima de nutrientes digestíveis acima das exigências de mantença, que o animal ingeriria por unidade de alimento ofertado.…”

RESUMO -Foi realizado um experimento com o objetivo de estudar os efeitos de níveis de oferta de palha de arroz amonizada com uréia no consumo voluntário (CMS) e na digestibilidade da matéria seca (DMS) e no consumo, na excreção, na digestibilidade e no balanço de N. Foram utilizados 15 ovinos adultos, machos, castrados, com peso médio de 63,8 kg, mantidos individualmente em gaiolas metabólicas. Os níveis de oferta de palha utilizados foram: 1,5; 3,0; 4,5; 6,0; e 7,5% do peso vivo (PV). Um suplemento (200 g/animal/ dia de milho) foi utilizado para fornecer energia disponível aos microrganismos do rúmen. Não houve efeito do nível de oferta de palha sobre a DMS, a excreção de N na urina, a digestibilidade do N e o balanço de N, sendo os valores médios de 58,6%, 8,23 g/dia, 44,74% e 0,29 g/dia, respectivamente. Houve efeito linear do nível de oferta no consumo e excreção de N nas fezes. Os consumos de MS e MS digestível (MSD) aumentaram linearmente até os níveis de oferta de 3,0 e 4,3%, respectivamente. Estes níveis de oferta resultaram em 23,9 e 37,4% de sobras, respectivamente. Baseando-se no consumo de MSD acima das exigências de mantença (0,12 energia digestível Mcal/kgPV 0,75 ), para maximizar o desempenho por unidade de palha ofertada, recomenda-se fornecer cerca de 123,05 g/kgPV 0,75 de palha de arroz amonizada. Quando o objetivo for apenas atender a mantença dos animais, níveis inferiores a 123,1 g/kgPV 0,75 são aceitos. Níveis superiores não são recomendados, pois haverá desperdício de palhas, sem haver incremento na resposta animal.Palavras-chave: amonização, balanço de nitrogênio, consumo voluntário, digestibilidade, níveis de oferta, uréia Voluntary Intake, Digestibility and Nitrogen Balance in Sheep Fed Ammoniated RiceStraw in Different Allowance Levels ABSTRACT -An experiment was conducted to study the effects of allowance of ammoniated rice straw on the voluntary intake (VI) and digestibility of dry matter (DMD), and on the intake, excretion, digestibility and N balance. Fifteen adult sheep, males, castrated, with average weight of 63.8 kg, individually kept in metabolic cages, were used. The levels of straw fed to the animals were: 1.5; 3.0; 4.5; 6.0 and 7.5% of live weight. A supplement (200 g/animal/day of corn) was used to supply available energy to the ruminal microorganisms. There was no effect of the level of straw offer on DMD, excretion of N in the urine, digestibility and balance of the N, and the average values were 58.6%, 8.23 g/day, 44.7% and 0.29 g/day, respectively. There was linear effect of the offer level on the intake and excretion of N in the feces. The DM and DMDs intake linearly increased up to 3.0 and 4.3%, respectively. These allowance levels produced 23.9 and 37.4% of orts, respectively. Based on the intake of DMD above the maintenance requirements (0.12 digestible energy Mcal/kgPV 0.75 ), to maximize the animal performance per unit of straw fed is recommended to supply about 123.05 g/kgPV 0.75 of ammoniated rice straw. When the objective is just to meet the maintenance requi...
