ABSTRACT:

A total number of one hundred weanling New Zealand White rabbits aged five weeks were used in this study. Rabbits were randomly distributed into ten experimental treatments; each one contains 5 males and 5 females in individual cages. Five levels (0, 5, 10, 15 and 20 %) of wheat screening by-product (WSP) and each level was fed without or with addition of enzyme preparation in 5×2 factorial design arrangement. Enzyme preparation ( containing β-Xylanase and α-Amylase) was added at 0 and 500 g/ ton of diets, during the experimental period from 5 to 12 weeks of age.

The obtained results could be summarized as follows: The rabbits fed diet containing 5% WSP with enzymes significantly recorded the highest values of body weight, body weight gain and relative growth rate followed by those fed diet containing 10% WSP with enzyme addition. The rabbits fed diet containing 20% WSP without enzymes recorded the lowest significant values in these respects. The rabbits fed diet containing 20% WSP with enzymes consumed the highest amount of feed compared with those for other groups. The best feed conversion ratio was recorded for rabbits fed diet containing 5% WSP with enzymes additions followed by those for control, 10 and 15% WSP with enzymes addition compared with all other dietary treatments. Enzymes supplementation in diets containing WSP significantly improved the digestibility coefficients of nutrients and carcass traits of rabbits compared with other groups. Total protein, cholesterol and urea were significantly decreased by increasing the level of WSP in the experimental diets. However, the differences between rabbits fed diets containing different levels of WSP with or without enzymes addition and the control diet in albumin and globulin was not significant. Rabbits fed diets containing different levels of WSP and provided with enzymes recorded significantly the lowest values of cholesterol compared with those fed the diets containing WSP without enzymes and control diet. The addition of enzymes in diets containing WSP significantly improved the liver functions. Chemical composition of meat did not significantly differ with the WSP and enzymes addition. Results showed an improvement in average values of net revenue, economical efficiency and relative economical efficiency due to feeding growing rabbits on diet containing 5% WSP with enzyme preparation.

 In conclusion, use of the WSP can be successfully fed at level 5 % of growing rabbit diets with enzymes supplementation (β-xylanase; α-amylase) without any adverse effect on growth performance and economical efficiency, under Egyptian conditions.

ABSTRACT

A total number of sixty weanling New Zealand White (NZW) rabbits aged five weeks old was used in this study. Rabbits were randomly distributed into 6 treatments; each one contains 5 males and 5 females. Three levels of corn cobs and two levels of enzymes preparation were used in a 3 x 2 factorial arrangement. Corn cobs were used at levels of 0 (control), 10  and 20 % of the diets. Enzymes preparation (containing cellulase, b-glucanase, a-amylase, protease and lipase) was added at 0 and 500 g/ ton of diet. Water and feed in pelleted form were offered ad-libitum during the experimental period from 5 to 12 weeks of age.

The obtained results showed that rabbits fed the control and 10% corn cobs diets with enzymes recorded the significantly values of body weight, body weight gain and relative growth rate. The rabbits fed the control diet with enzymes consumed the highest amount of feed followed by those fed the control diet without enzymes then the 10% corn cobs with enzymes diet. The best feed conversion ratios were recorded for rabbits fed the diet containing 10% corn cobs with enzymes additions than those fed the control diet with enzymes addition compared with all other dietary treatments. Addition of enzymes in all experimental diets significantly improved digestibility coefficients of nutrients compared with those without enzymes addition.

The interaction between corn cobs levels and enzymes addition had no significant effect on carcass and dressing percentages. Dietary treatments significantly reduced total protein and globulin by increasing the level of corn cobs in the experimental diets. The addition of enzymes in diets containing corn cobs significantly improved the liver functions. Chemical composition of meat did not significantly differ due to the effect of dietary treatments. Rabbits fed 10% corn cobs diet with enzyme additive showed the highest economical efficiency values.

Conclusively, the present results showed that the use of corn cobs can be successfully fed at levels up to 10% of growing NZW rabbits diet supplemented with enzymes without adverse effect on growing rabbits performance.

ABSTRACT:

The present study was carried out to investigate the effect of replacing 25 % of soybean meal protein in diets by each of dried portulaca oleracea leaves, azolla pinnata and berseem seeds by-products (okaba) on productive and reproductive performance of New Zealand White (NZW) does rabbits. A total number of 48 breeding (NZW) rabbit does and 12 bucks (6 month old) with nearly similar weights and divided at random into four groups (12 does and 3 bucks in each). First group was  fed pelleted diet contains soybean as the main source of protein as a control, in the other three diets substituted 25% of soybean meal protein for control diet by dried portulaca oleracea leaves, azolla pinnata and okaba seeds proteins, during the experimental periods. The experimental rations were formulated isonitrogenous and isocaloric. Results of the experiment showed that feeding diets containing different sources of protein had no significantly effect on does weight and weight gain at the end of experimental period. The highest values of conception rate and number of parturition /doe were obtained when does fed on the control ration (79.43 % and 4.03), respectively. The highest means litter size and litter weight at birth and at weaning age were recorded by rabbits fed control diet, followed by those fed portulaca, azolla and okaba diets. The okaba group showed the highest total feed intake value followed by those fed on azolla, while group fed soybean meal consumed the lowest total feed intake amount during the lactation period. The highest milk yield during suckling period was recorded by okaba group as compared to other groups. The best feed conversion value was recorded by rabbits fed diet contains okaba, while the rabbits fed azolla diet had the worst feed conversion for bunny gain. The highest values of bunny weight at birth, weaning and gain were recorded by okaba group as compared to other groups. The percentages of pre-weaning mortality among experimented groups were significantly differ. The lowest percentage of pre-weaning mortality rate (4.35%) was obtained by does fed okaba diet. From economical efficiency point, control group recorded the highest net return and economic efficiency followed by portulaca and azolla treatments, however okaba group had the lowest net return and economic efficiency.

 Abstract : A (3X3) factorial design experiment was conducted to study the effect of three levels of crude protein (16, 18 and 20%) and three levels of copper sulfate (0, 100 and 200 mg/kg diet) as a growth promoter on productive and reproductive performances, egg quality, blood serum constituents and economical efficiency of laying quail hens through 8 weeks. A total number of 270 hens and 135 males of Japanese quail at 8 weeks of age with nearly equal body weight and average rate of laying were randomly divided into 9 groups (30 hens and 15 males each). Each group of birds was sub divided into 3 replicates (10 hens and 5 males) and each replicate was housed in one wire cage. The results showed that the layer body weights at 12 or 16 weeks and weight gain at 12-16 and 8-16 weeks of age were significantly increased with increasing crude protein level from 16-18 or 20%, while there were no significant differences between the groups fed 18 and 20% crude protein throughout the experimental intervals and the whole period. Egg number, rate of laying and egg mass of laying quail hens increased with increasing crude protein at levels 16-18 or 20% (except at 12-16 week of age), while insignificant differences were found between the groups fed 18 and 20% crude protein throughout the experimental intervals and the whole period. Addition of copper sulfate at levels of 100 and 200 mg/kg to laying quail diets significantly improved egg number, rate of laying, egg mass and feed conversion ratio except at 8-12 weeks of age as compared with group non-supplemented with copper sulfate during the experimental period. The highest values of body weight and egg mass were recorded with 20 % protein plus 100 mg copper sulfate/kg diet, while, the best values of feed conversion and The highest values of egg number and rate of laying were recorded with 20 % protein plus 200 mg copper sulfate/kg diet from 8-16 weeks of age for quail layer as compared with other treatments. Laying quails hens fed diet contained copper sulfate levels significantly increased hatchability of fertile eggs percentage (except at 12 wks of age) as compared with those un-supplemented group. Various levels of crude protein or copper sulfate containing diets did not significantly affect on egg quality parameters, while egg yolk cholesterol was significantly decreased with increased copper sulfate levels. The highest values for total serum protein and serum albumin were recorded with experimental groups fed 18 or 20% protein levels compared with those received 16% protein diet, while serum cholesterol values were significantly decreased with increased crude protein. However, dietary copper sulfate supplementation reduced serum tri-glycerides, total cholesterol and low density lipoprotein cholesterol, but increased serum high density lipoprotein cholesterol. The best value of economic efficiency was recorded with laying quail hens fed 18% protein with 100 mg copper sulfate/kg diet compared with other treatment groups.

Abstract : This study was conducted to evaluate the effect adding of Saccharomyces cerevisiae, Bacillus subtilis and Bacillus licheniform, black seed oil versus, virginamycin and zinc bacitracin to growing chick's diets at level of 0.1%, for each. Growth performance, digestibility, carcass treats, meat composition, serum blood constituents and economical efficiency of growing chicks were studied. A total of 180 unsexed one-day old chicks, were divided into 6 treatments of 30 chicks each in three replicates. The experiment was terminated when chicks were 12 weeks of age. The results showed that, addition of black seed oil, Saccharomyces cerevisiae and Bacillus subtilis and Bacillus licheniform in the experimental diets increased body weight, body weight gain. Chicks fed diets supplemented with black seed oil and virginamycin were significantly lower in their feed consumption. While, Chicks fed diet supplemented with saccharomyces cerevisiae consumed the highest amount of feed. The best feed conversion ratio was recorded with chicks fed diets contained black seed oil or virginamycin. All the treatments insignificantly affected dressing, giblets percentages, composition of breast Meats and blood serum constituents as compared with those of the control. Chicks fed diets supplemented with either black seed oil, virginamycin or Bacillus subtilis and Bacillus licheniform had significantly decreased abdominal fat percentages. The Addition of Saccharomyces cerevisiae, black seed oil and Bacillus subtilis and Bacillus licheniform significantly improved digestibility coefficient of dray matter and crude protein. The best relative economical efficiency was recorded by black seed oil flowed by virginamycin addition. It was concluded that black seed oil, Bacillus subtilis and Bacillus licheniform and Saccharomyces cerevisiae, could serve in growing chicks diets. However, further research is required to better understand the role of natural feed additives in poultry nutrition and their implications in human health.

Abstract: The objective of this work was to study the impact of addition of natural feed additives as dinaferm (Saccharomyces Cerevisiae), biotop (Bacillus Subtilis and Bacillus Licheniform) and black seed oil versus, some antibiotics as amoxicillin and zinc bacitracin to laying hen diets on productive performance, serum components, digestibility, semen quality, fertility, hatchability and economical efficiency. A total number of 180 layer hens   and   24 cockerels   of   local   strain "Al - Salam" were fed the experimental diets from 32 to 43 weeks of age. Layer hens and cockerels were divided into 6 treatment groups in individual cages in open system. The first group were used as control (fed without any additives), while the other five groups were fed the same control diet supplemented with dinaferm, biotop, black seed oil, Amoxicillin and Zinc bacitracin at levels of 0.1, 0.1, 0.1, 0.02% and 0.05%, respectively. The results showed that, addition of different feed additives significantly (P <0.05) improved egg number (EN), egg mass (EM) and feed conversion (FC) while, insignificantly affected egg weight ( EW ) as compared to the control group. Addition of dinaferm was increased significantly (P<0.05) EN and EM than control and other treated groups. The highest values of EN and the best FC were recorded by dinaferm addition. Addition of dinaferm increased significantly (P<0.05) feed intake (F1), while, amoxicillin and zinc bacitracin addition decreased significantly (P<0.05) FI as compared to the control group. Addition of different feed additives to laying hen diets insignificantly affected on globulin, globulin / albumin ratio and cholesterol as compared to the control group. Addition of dinaferm, amoxicillin and Zinc bacitracin increased significantly (P<0.05) total protein and albumin while, biotop and black seed oil addition insignificantly affected total protein and albumin as compared to the control group. The Addition of feed additives insignificantly affected most digestibility coefficient parameters while, amoxicillin and Zinc bacitracin addition decreased significantly (P<0.05) digestion coefficients of dry matter (DM), organic matter (OM) and crude protein (CP) as compared to the control group. Addition of different feed additives improved significantly (P<0.05) semen- ejaculate value, sperm - cell concentration (x106/ml.) and sperm motility % while, decreased significantly (P<0.05) dead spermatozoa and sperm abnormalities as compared to the control group. Addition of dinaferm and Zinc bacitracin improved significantly (P<0.05) fertility and hatchability percentage, as compared to control group. The best relative economical efficiency was recorded by dinaferm flowed by black seed oil addition compared to the control and other treated groups. It was concluded that natural feed additives dinaferm, biotop and black seed oil could serve in laying hens diets. However, further research is required to better understand the role of natural feed additives in poultry nutrition and their implications in human health.

 Egypt Poult. Sci. Vol. 26 (1) :(137-158)  March (2006).

Abstract: A total number of 72Matrouh laying hens (local strain) at 32 weeks of age were used to study the effect of using 50% wheat bran in the laying diets and the possibility to improve the feeding value of wheat bran (WB) when supplemented with some feed additives. Hens were housed in individual cages and were randomly divided into six equal treatments (12 birds each) and were approximately similar in their body weight. Treatment 1 birds were received the control diet contained 16% CP and 2703 kcal ME/Kg. Treatment 2 birds were received the basal wheat bran diet (WB-diet) contained 16.01% CP and 1841 Kcal ME/Kg. Birds of Treatments 3,4,5 and 6 were received the WB-diet supplemented with either 1.0% sodium sulphate (SS), 0.1% kemzyme (KE) , 1.0% (SS) plus 0.1% (KE) , or 0.1%(KE) plus 1.0% Radish extract (RE) , respectively. Birds were fed the experimental diets for three months. Results showed that WB-diet significantly reduced feed intake and numerically decreased egg number. Addition of SS or KE+RE increased egg number and egg mass compared to hens fed WB-diet alone. WB-diet increased level of calcium and phosphorus in serum while decreased cholesterol, low density lipoprotein (LDL) and high density lipoprotein (HDL) in yolk compared to hens fed control diet. It could be concluded that the detrimental effect of inclusion of 50% wheat bran in Matrouh laying hen diets can be overcome by addition of SS or KE+RE.

Abstract: A total number of 150 Matrouh laying hens a local strain of 32 weeks old were used to study the effect of using some medicinal plants as feed additives on performance, egg quality, digestibility, blood constituents and economical efficiency of laying hens. Hens had nearly similar initial body weight and were randomly divided into five equal treatment groups (30 hens each) and were housed in individual cages in an open system house.  Treatment 1 received the basal diet (control). Treatments 2, 3 and 4 received the basal diet supplemented with fenugreek ( F.S), chamomile (CH.F) and  radish (R.R) at the levels of 0.5% for each, respectively, while the fifth treatment received kemzyme dry product (K.M) at the level of 0.1%. Hens were fed the experimental diets for three months.

The results obtained could be summarized as follows:

  • 1- Addition of R.R at the level of 0.5% numerically increased egg number and egg mass by 12.42 and 12.43 %, respectively, compared to the control group.
  • 2- Hens fed basal diet supplemented by R.R, K.M, CH.F and F.S numerically increased egg number than those fed basal diet (control) by 12.42, 7.31, 5.42 and 2.23%, respectively.
  • 3- Feed consumption with hens fed control diet had significantly the maximum amounts of diet compared to the other treatments throughout all intervals studied.
  • 4- In addition F.S, CH.F and K.M supplementation decreased significantly feed consumption compared to control and R.R groups.
  • 5- Addition of K.M, CH.F, R.R and F.S improved feed conversion compared to control group during 40- 43 wks. of age.
  • 6- All treatments did not cause significant effect on egg quality traits and digestibility values of laying hens.
  • 7- Addition of K.M supplementation significantly increased plasma total protein and globulin values followed by those fed diets including R.R, while hens fed diets containing CH.F, F.S and control did not statistically differ.
  • 8- Addition of CH.F significantly decreased total cholesterol and GOT values compared with the other groups. The highest values of GPT value recorded by hens fed diet containing R.R..
  • 9- The best relative economical efficiency was recorded with hens fed R.R followed by those fed either K.M, CH.F or F.S, respectively.
  • 10- These results indicated that the diets containing R.R, K.M, CH.F and F.S were more economical than the control diet.
