Daniellia Oliveri

The study was carried out to determine the effect of Daniellia oliveri leaf meal (DOLM) in complete diets on feed intake, digestibility, nitrogen utilization and growth of Savannah Brown goats in a 90-day trial using the completely randomized design. Thirty-six does, with an average initial weight of 10.66 kg, were randomly divided into four groups of similar body weight (BW) and allocated to one of the four complete diets with DOLM inclusion levels at 0%, 20%, 30% and 40% respectively. Intakes of dry matter (DM) and organic matter (OM), and cost/kg BW gain were higher (p<0.05) in the control diet than in the treatment diets. Intake of crude protein (CP) was higher (p<0.05) for the control diet compared to the 30 and 40% DOLM diets. Feed conversion ratio and faecal nitrogen excretion of animals on 20% DOLM diet were lower (p<0.05) than other diets. Final body weight, total weight gain and average daily weight gain were not (p>0.05) affected by the diets. Digestibility of DM and CP, and nitrogen balance of animals on 0 and 20% DOLM diets were higher than those on 30 and 40% DOLM. Digestibility of OM and crude fibre was lowest (p<0.05) for the control diet relative to other diets. Nitrogen intakes (NI) of 0 and 40% DOLM diets were lower (p<0.05) compared to those of 20 and 30% DOLM diets. Nitrogen absorbed (NA) and nitrogen retention (as % of NA) were marginal (p<0.05) for 30% DOLM diet relative to other diets Nitrogen retention (as % of NI) was highest and lowest (p<0.05) for 20%DOLM diet, and 30 and 40% DOLM diets respectively. The study shows that Daniellia oliveri leaf meal can be used up to 40% inclusion level to replace 100% of maize offal in the diet of Savannah Brown goats without adversely affecting the performance of the animals.

1. The histidine requirement of growing kittens was determined from an experiment in which forty-eight kittens were randomly allocated to six amino acid-based diets supplying: 1.0, 1.5, 2.0, 2.5, 3.0 or 4.5 g histidine base/kg diet.2. By 48 d it was obvious that 1.0 and 1.5 g histidine/kg diet were grossly inadequate so the kittens receiving these two diets were removed from the experiment. The other four groups of kittens continued to receive their diets for a total of 128 d.3. Mean daily weight gain, nitrogen retention and food intake attained plateau values at 2.1 g histidine/kg diet.4. Blood samples taken at 25 and 48 d after kittens were given the diets showed a significant effect of dietary histidine on haemoglobin (Hb) concentration. Hb and packed cell volume (PCV) attained asymptotic values at 3.0 g histidine/kg diet at 48 d. At 128 d, kittens consuming diets containing 2.0–4.5 g histidine/kg had similar Hb and PCV values.5. Cataracts of both eyes were observed in two of nine female kittens which had received diets containing either 2.0 or 2.5 g histidine/kg.6. A concentration of 3 g histidine/kg diet is recommended as a practical guide for feeding kittens.7. There was a rectilinear relation (r2 0.99) between the logarithm of the histidine concentration of plasma and the concentrationof histidine in the diet over the range 1.5–3.0 g histidine/kg diet.

A feeding trial was conducted to determine the effect of graded levels of dehulled and cooked castor oil bean (Ricinus communis L) meal (CBM) and supplementary DL-methionine on growth performance and certain blood parameters of broiler finishers. One hundred and eighty 6-week old broiler birds (Anak strain) were randomly divided into 12 groups of 15 birds each. The groups were randomly assigned to 12 isocaloric (2.90 Mcal/kgME) and isonitrogenous (21.00%CP) diets in a 4 x 3 factorial arrangement involving a control (0%), three cooked castor oil bean meal levels (10,15 and 20%) and three DL-methionine levels (0,0.25 and 0.5%). Each treaiment was replicated thrice with 5 birds each. Feed and water were supplied ad libitum from 42 to 70d of age. The results showed that above 15% CBM inclusion level, average daily feed intake (ADFI) and average daily weight gain (ADWG) were significantly (P<0.05) decreased. There were also significant reductions (P<0.05) in efficiencies of feed and protein utilization, and in apparent retention of dry matter (DM), nitrogen, ether extract (EE) and nitrogen-free extract (NFE). While packed cell volume was not significantly (P>0.05) affected by CBM or DL-methionine, haemoglobin concentration (Hb) was significantly (P<0.05) increased at 20% CBM level. Supplementation with DL-methionine improved (P<0.05) weight gain at the 15 and 20% levels of CBM inclusion; improved Hb and efficiencies of feed and protein utilization at the 20% level of CBM inclusion, improved nitrogen retention at the 0% level of CBM inclusion; improved EE retention at the O and 20% levels of CBM inclusion, and improved NFE retention at the 15% level of CBM inclusion. The results of this study indicate that processed CBM can be included in broiler finisher diet at 15% level with DL-methionine supplementation to obtain normal growth in broiler birds.

A study was carried out to investigate the effect of feeding two varieties of cowpea haulm on  growth performance, nutrient digestibility and nitrogen balance in Red Sokoto bucks. The  experiment consisted of 15 Red Sokoto bucks of average weight of 10kg, which were balanced  for weight and randomly assigned to three dietary treatments with five bucks per treatment in  a complete randomize design. The three treatment diets consisted of Brachairia decumbens  hay as basal diet and concentrate diets which were supplemented with cowpea haulms at 0%  (Control), 10% (SAMPEA14) and 10% (SAMPEA15). The study lasted for 90 days. Total dry  matter intake (TDMI, g/day), total weight gain (TWG, kg), faecal (unit) and urine (unit)  outputs were recorded. Results indicated that the TDMI were different (P<0.05) with higher  intake (237.64 g/day) in bucks fed control diet, followed by 223.00 g/day 10% SAMPEA 15  and 10% haulm of Sampea 14 (206.49g/day) in the concentrate. The TWG and average daily  weight gain increased by 59.77% and 59.76%, respectively with respect to 10% SAMPEA 14  haulm inclusion compared to the control diet. The digestibilities of dry matter (DM), crude  protein (CP), crude fibre (CF), ether extract (EE) and nitrogen free extract (NFE) were  higher (P<0.05) in bucks fed diet constaining 10% SAMPEA 14 inclusion level compared to  the treatment diets. The quantity of N retained by the bucks was higher (P<0.05) with the  inclusion of 10% of SAMPEA 14 (3.79 g/day) compared to those fed 10% SAMPEA 15 (1.18  g/day) and the control diet (0.68 g/day). It is concluded that farmers should include 10%  SAMPEA 14 in concentrate diet of Red Sokoto bucks for optimum performance under smallholder production system.     Une étude a été menée pour étudier l'effet de l'alimentation de deux variétés des haulms de niébé sur la performance de croissance, la digestibilité des nutriments et l'équilibre azoté chez les mâles Red Sokoto. L'expérience s'est composée de 15 bucks rouges de Sokoto de poids moyen de 10kg, qui ont été équilibrés pour le poids et aléatoirement assignés à trois traitements diététiques avec cinq dollars par traitement dans une conception randomize complète. Les trois régimes de traitement se sont composés deBrachairiadecumbenshay comme régime basal et régimes concentrés qui ont été complétés avec des haulms de niébé à 0% (contrôle), 10% (SAMPEA 14) et 10% (SAMPEA 15). L'étude a duré 90 jours. La consommation totale de matière sèche (TDMI, g/day), le gain de poids total (TWG, kg), les sorties fécales (unitaires) et urinaires (unitaires) ont été enregistrées. Les résultats ont indiqué que le TDMI était différent (P<0.05) avec une consommation plus élevée (237.64 g/jour) dans le régime de contrôle alimenté par les mâles, suivi de 223.00 g/jour10% SAMPEA 15 et 10% de transport de Sampea 14 (206.49 g/jour) dans le concentré. Le TWG et le gain quotidien moyen de poids ont augmenté de 59.77 % et de 59.76 %, respectivement en ce qui concerne l'inclusion de 10 % de SAMPEA 14 haulms par rapport au régime de contrôle. Les digestibilités de la matière sèche (le 'DM'), des protéines brutes (le 'CP'), des fibres brutes (le 'CF'), de l'extrait d'éther (le 'EE') et de l'extrait sans azote (le 'NFE') étaient plus élevées (P<0,05) chez les mâles nourris à l'alimentation constaining 10% SAMPEA 14 niveau d'inclusion par rapport aux régimes de traitement. La quantité de N retenue par les mâles était plus élevée (P<0.05) avec l'inclusion de 10% de SAMPEA 14 (3.79 g/jour) par rapport à celles nourries 10% SAMPEA 15 (1.18 g/jour) et le régime de contrôle (0,68 g/jour). Il est conclu que les agriculteurs devraient inclure 10% SAMPEA 14 dans le régime concentré de bucksRed Sokoto pour une performance optimale dans le cadre du système de production des petits exploitants.

The Impact

The use of alternative feed for Sunda pangolin in captivity is one way to cope with a shortage of feed. The aims of the research was to determine the impact of the use of alternative feed toward feed consumption and daily weight gain of pangolin in captivity. The research was conducted at Research Forest Dramaga, Bogor. The research material used by 4 individual pangolin consists of 2 males and 2 females with an average weight of 4.28 ± 0.22 kg. Research using 4x4 Latin Square Design, with 7 days of preliminary period and 14 days of data collection. The treatment applied were 4 alternative feeding i.e A= 50% kroto + 50% egg; B= 50% kroto + 50% tofu; C= 50% kroto + 20% egg + 30% tofu; D= 50% kroto + 18% egg + 26% tofu + 6% termites. The results showed that the effect of alternative feed not significantly (P<0.05) on feed consumption and body weight gain pangolin. Pangolin with treatment C consumed feed based on dry matter as much as 63.08 grams per day or 10.46% from body weight and the biggest weight gain 35.0 grams per individual per day.

This study was conducted to assess the effect of common salt supplementation on the performance of young sheep fed maize bran and ground nut hay as basal diet. It covered a period of 12 weeks. A 3×3 Latin square design was employed in the experiment. The daily feed intake, body weight gain and feed conversion efficiency were measured during the experimental period. Results showed that the inclusion of common salt at the level of 1.0% of feed had no significant effect on feed intake (p>0.05). There was depressed feed intake as quantity of salt increased from 0.0%, to 0.5% and 1.0%. The best mean average daily weight gain of 43.45%was obtained with the 1.0% treatment. Salt inclusion up to 1.0% level in sheep ration, had no adverse effect on performance, it rather gave a more favorable weight gain and conversion efficiency. These findings are of very practical significance in sheep fattening, especially for farmers in rural setups.

Digestible Crude Protein

SUMMARYEight feeding trials on cattle showed that the response in live-weight gain was curvilinear when protein or energy level was varied independently in rations based on poor quality roughages to which cereals and groundnut were variously added to give a range of protein and energy intakes. Live-weight gain was increased by 0·12 lb/day for each 0·1 lb additional digestible crude protein/day at levels of intake below 0·7 lb/day and by 0·03 lb/day at higher levels. It was increased by 0·4 lb/day for each additional 0·1 lb starch equivalent daily/100 lb live weight at total intakes below 0·9 lb daily/ 100 lb and by 0·2 lb/day at higher levels. Over the range 0·5–2·0 lb digestible crude protein daily and 0·7–1·2 lb starch equivalent daily/100 lb live weight the effects of these nutrients were additive.A Latin square nitrogen balance trial demonstrated that a portion of the nitrogen from a protein supplement was retained in the body despite the excretion of the greater part of it in the urine and a further part in the faeces. Nitrogen retention was increased by a supplement of readily available energy through a decrease in urinary nitrogen loss. Nitrogen balance was not increased by a supplement of a fibrous energy source because this induced an increase in faecal nitrogen loss.In a further feeding trial milk yield was found to be affected in a similar manner to growth. At a yield of 30 lb/day the response per lb starch equivalent added to the diet was 0·5 lb milk including 0·05 lb solids not fat and to an increase of 0·1 lb digestible crude protein daily it was 0·25 lb milk including 0·025 lb solids not fat.

Animal production in tropical regions is commonly limited by the low crude protein content and digestibility of pastures, particularly during the dry season. The objective of the present study was to evaluate the effect of including Enterolobium cyclocarpum leaves (ECL) (0%, 15% and 30%) in diets as a partial replacement for lucerne on dry-matter intake (DMI), weight gain and nitrogen (N) balance in growing Saanen goats (12.6 ± 3.2 kg at 3 months of age) and the digestibility of the diet. Daily weight gain, DMI and digestibility were analysed in a 3 × 3 Latin square design replicated three times. The inclusion of ECL did not affect daily weight gain or DMI (P &gt; 0.05). There were no significant (P &gt; 0.05) differences for N intake among the diets, but the inclusion of 30% ECL significantly (P = 0.01) increased N excreted in faeces. These results suggest that ECL can be used as a partial substitute of lucerne in diets for growing goats, without affecting animal performance.
