Significant Difference

It was confirmed in metabolic experiments with 4 individuals of roe deer (2 males and 2 females with the live weight of 20.8 and 17.9 kg, respectively) that due to the animals’ selective choice of a part of feeds there was no significant difference in the intake of lucerne hay of different quality and high-quality meadow hay (515.86 ± 66.97 and 597.82 ± 94.87 g, respectively). However, different quality of lucerne hay influenced the animals’ intake of crude protein and crude fibre. When the animals were fed meadow hay, they took in significantly less crude protein and fibre and significantly more nitrogen-free extract, fat and ash. Digestibility of crude protein was observed to be significantly decreased in hay of lower quality (by 10.1%). Digestibility coefficients for crude protein, crude fibre, organic matter and fat were significantly lower in grass hay compared to lucerne hay. Based on the coefficients of nutrient digestibility it can be stated that meadow hay, even if of excellent quality, is not a suitable supplement for the roe deer.

Twelve indigenous growing cattle (live weight 130.00 ± 1.67 kg) were selected and divided into four groups having three animals in each group. Group A, B, C and D supplied 3.0% urea + 2.0% midden soil, 3.0% urea + 3.0% midden soil, 3.0% urea + 4.0% midden soil and 3.0% urea + 5.0% midden soil treated rice straw. In addition to this all the animals were supplied 2 Kg green grass, 450 g concentrate mixture and 40 g salt per 100 kg body weight. Rice straw treated with 3.0% urea+ 2.0% midden soil resulted an improvement in crude protein content of rice straw from 3.30 to 7.08% which was further increased by 7.40, 7.90 and 8.14% treatment with 3.0% urea + 3.0% midden soil, 3.0% urea + 4.0% midden soil and 3.0% urea + 5.0% midden soil respectively. The addition of 5.0% midden soil as a urease source with 3.0% urea (D) treated rice straw not only significantly (P<0.01) increased the coefficient of digestibility of DM, CP, CF, EE and NFE but also significantly (P<0.05) increased the coefficient of digestibility of OM than other treatments. Digestible organic matter (DOM), crude protein (DCP), digestible crude fibre (DCF), digestible nitrogen free extract (DNFE) and total digestible nutrients (TDN) contents were significantly (p<0.01) higher in diet D in comparison to diet A, B and C.

Feeding Diets

We investigated the effects of feeding diets with different starch sources on fermentation in the rumen, duodenal nutrient flow and nutrient digestibility. The basis of the diets was maize silage and alfalfa hay supplemented with wheat meal in diet W, or maize meal in diet M. The experiment was performed on four Black-Spotted bulls with mean live weight of 525 kg, which were fed twice daily at 06.30 and 18.30 h. Experimental animals were fitted with ruminal fistulae and duodenal T-shaped cannulae. Cr2O3 was used as a marker of nutrient flow to the duodenum. Rations were formulated so that the ratio of starch to crude fibre (CF) was 2.1:1 and the percentage of CF was maintained at 17% (DM). Duodenal chymus was collected at 2-h time intervals. Starch origin significantly affected ruminal fermentation. Concentration of propionic, butyric and lactic acid was higher with wheat than with maize meal. When the maize meal was the source of starch there was a significantly higher flow of fat, CF, nitrogen-free extract, and starch into duodenum. Differences in duodenal flow of crude protein were not significant across the starch sources. Intake of wheat meal or maize meal increased duodenal flow relative to intake by 33% or 42 % respectively. The apparent digestibility of dry matter (76 ± 2%), crude protein (67 ± 0.9%), CF (64 ± 1.9%), nitrogen-free extract (82 ± 1.5%) and organic matter (76 ± 1.3%) was significantly higher by offering wheat meal.

SUMMARYSixty-four young male Sudan desert lambs were group-fed for 87 days on four diets, all containing approximately 10% crude protein. The four diets contained 0, 1·3, 1·7 and 2·7% urea, respectively.Average daily gains were 0·15, 0·14, 0·14 and 0·13 kg; feed conversion ratios (kg of feed required to produce 1 kg live-weight gain) were 7·26, 8·14, 8·92 and 7·92; dressing percentages were 43·6, 42·1, 44·1 and 42·3.Digestibility trials with lambs fed on diets with 0 or 2·7% urea gave higher digestibility coefficients for crude fibre and nitrogen-free extract for the urea-supplemented lambs. Crude protein digestibility and nitrogen retention values were lower for urea-supplemented lambs.

Nulliparous crossbred does were used to study the effects of concentrate:lablab ratio (CL) and stage of pregnancy on nutrient intake and digestibility. Treatments consisted of four concentrate and lablab combinations on a gram:gram basis: 20:130, 40: 110, 80:70 and 100:50 and two stages of pregnancy: second and fourth week of pregnancy Concentrate intake increased as level increased up to 80g/day offered while lablab intake increased from 50 to 130g/day offered. Doe weight and metabolic size were similar for all treatments. Total feed intake was not affected by concentrate and lablab levels. Dry matter intake was lower for 100:50 CL than other treatments. Ether extract and crude fibre intakes decreased with increase in concentrate levels. Dry matter and nitrogen free extract digestibility were higher for 80:70 CL than other combinations. Crude fibre digestibility was higher for 80:70 than 40:110 and 100:50 CL Crude protein retention was higher for 80:70 than 20:130 and 100:50 CL. Fetal growth requirement, total protein requirement and balance of protein were high at 80:70 and 100:50 CL. During pregnancy, dry matter and all nutrients intake were higher in the second than fourth week. Ether extract, crude protein and nitrogen free extract digestibilities were lower in the second than fourth week of pregnancy. Fetal growth requirement and balance of protein were higher in the second than fourth week of pregnancy relationship between feed intake (g DM/day) and nutrient digestibility was negative. The relationship between feed intake (g DM/kg body weight/day) and feed intake (g DM/kg LW0.75/day) was however, positive for all the nutrients except crude protein. For the small scale rabbit producer in developing countries, it is feasible to maintain rabbits on combinations of concentrate and lablab during pregnancy

Mixture of bovine blood and rumen digesta (BBRDM) was evaluated for 56 days as a replacement for soybean meal (SBM) and groundnut cake (GNC) at 100% on protein to protein basis in the diets of growing pigs to assess the nutritive value of BBRDM on the growth performance, nutrient digestibility and cost benefits. Hence, a total of 18 growing pigs were allotted on weight equalization basis into three dietary treatments consisting of six pigs per treatment in a completely randomized design. Three diets were formulated such that T : served as the control diet without BBRDM but contained both soybean meal and 1 groundnut cake. T : BBRDM replaced soybean meal and T : BBRDM replaced groundnut 2 3 cake. Result indicated that BBRDM contained 28.65% crude protein, 13.17% ether extract, 5.26% crude fibre, 11.29% ash and 31.65% nitrogen free extract. Dietary treatments did not significantly (P>0.05) influenced the growth parameters observed in this study. Although there were no significant (P>0.05) difference on the nutrient digestibility parameters investigated but birds in T recorded highest numerical values for crude protein (77.23), 3 crude fibre (62.46%), ether extract (92.33%), nitrogen free extract (89.61%), ash (70.28%) and nutrient dry matter (91.67%) while the least values were obtained from birds in T . Cost 1 of feed decreased with the inclusion of BBRDM while the cost per weight gain also improved with the replacement of the conventional feed ingredients. The result also showed that an appreciable amount of money was saved when BBRDM was included in the ration of growing pigs. It is therefore concluded that BBRDM could be used as an animal protein source to compliment plant protein source such as soybean meal and groundnut cake in the diet of growing pigs.

The potential of sugarcane peels as a substitute for maize offal in rabbit diets and its effect on growth, nutrient digestibility, and carcass characteristics were studied. Twenty five growing rabbits of mixed breeds and average body weight of 894±26.14g were used in a 7-week feeding trial. Five experimental diets were formulated in which sugarcane rind (SCR) was included at 0, 10, 20, 30 and 40% level to replace maize offal (weight for weight). The rabbits were balanced for weight and allotted to the treatments (n=5 rabbits/treatment) in a completely randomized design. Results obtained indicated that dry matter, crude protein, ether extract, nitrogen free extract, hemicellulose, acid and neutral detergent fibre intake and digestibility decreased with increasing level of sugarcane rind inclusion. Crude fibre intake (5.59-8.67 g/day) and digestibility (20.60-40.80%) however increased (P<0.05) as level of sugarcane rind increased in the diet. The 30% inclusion of sugarcane rind gave body weight gain (5.35 g/d) comparable to the control (6.41 g/d), 10 (7.78 g/d) and 20% (7.12 g/d) inclusion of sugarcane peels. Feed intake (44.61-40.59 g/d) decreased as the level of sugarcane rind increased in the diets. There was no significant (P>0.05) effect of sugarcane rind on metabolic body weight and feed efficiency. Inclusion of sugarcane rind at 30% level increased (P<0.05) thigh and head percentage but without any adverse effect on chest, loin, shoulder and skin. Based on the results, it is concluded that sugarcane rind is a good fibre source that can be used to replace maize offal up to 30% in rabbit diets.

One of the most important aspects of animal nutrition is digestibility of ingested materials which has a direct relationship with the health status of an animal. The effect of different fish meal alternatives (maggot, termite, grasshopper and lizard meals) on nutrient digestibility and carcass characteristics of broiler chickens was investigated in this 56 days feeding trial. One hundred and fifty broiler chicks (Marshal breed) were used for the study. Birds were assigned into five dietary groups of 30 chicks each and further divided into three replicates of 10 chicks each. Five experimental diets were formulated to contain 5% fish meal, maggot meal, termite meal, grasshopper meal and lizard meal in treatments 1, 2, 3, 4 and 5 (tagged T1 , T2 , T3 , T4 and T5 ) respectively in starter phase, while fish meal was replaced with 2.5% maggot, termite, grasshopper and lizard meals in treatments 2, 3, 4 and 5 respectively in finisher phase. The chicks were allocated into the four diets in a completely randomized design and housed in a deep litter pen with feed and water served without restriction. Results from dry matter, crude protein, crude fibre, ash, ether extract and nitrogen free extract digestibility showed significant (P<0.05) differences in the test ingredients on birds. Dry matter digestibility ranged from 88.35% in birds fed T3 to 91.86% in birds fed T5 . Crude fibre followed the same trend with the lowest (70.80%) in T3 and the highest (84.83%) in T5 , but ether extract digestibility was at the opposite trend where birds fed T3 had the highest (87.14%), and those on T5 gave the lowest (80.86%). Crude protein showed significant decrease across the treatments from 86.10% in T1 to 80.88% in T5 . Ash digestibility ranged from 68.84% in T2 to 77.05% in T1 . Results on cut-up parts showed that there were no significant (P>0.05) influence on all the parameters considered except in live weight, dressed weight and breast muscle weights where there were significant (P<0.05) differences. Internal organ proportions of the broiler birds showed no significant (P>0.05) effect of the test ingredients on all the parameters considered except in abdominal fat. It can be concluded that crude protein digestibility, live weight, dressed weight and breast muscle values in birds fed T2 (maggot meal) were higher than birds fed other test ingredients and as such recommended as an alternative to fish meal.
