AbstractThe productivity of indigenous goats in Africa is constrained by shortage of protein-rich feed especially in winter. This study investigated the nutritional value of mucuna forage (MF) and seed meal (MSM) as alternative protein sources for indigenous goats. Mucuna was planted in 3 parallel and adjacent fields and its foliage nutritional composition determined at 4, 8, 12 and 16 weeks after planting (WAP). MF was harvested at 14 WAP whilst mucuna pods were harvested at 28 – 30 WAP, shelled and the MSM chemically analysed. In a completely randomised design (CRD), 20 indigenous goats were randomly offered 5 treatment diets with, respectively, 0%, 25%, 50% and 100% MF and 100% MSM replacing broiler litter (BL), each with 4 replicates, for 82 days. Both mucuna foliage DM and CF contents increased (P < 0.001) whilst foliage CP, EE and ash contents decreased (P<0.001) with maturity. On the other hand, MSM contained high DM (90.7%), EE (3.7% DM) and CP (26.0% DM) but low CF (9.7% DM) and ash (5.5% DM) contents. Both body weight gain (BWG) and feed conversion efficiency (FCE) were not influenced by dietary mucuna incorporation (P > 0.05). However, dietary MF, particularly at the 100% level, decreased goat feed intake (FI) (P < 0.001) whilst 100% MSM increased (P < 0.001) this parameter. Mucuna had no effect on all carcass characteristics (P > 0.05) but increased (P < 0.05), particularly at the 100% MSM level, hot carcass weight and dressing percentage. There were no effects of mucuna on all biochemical and haematological indices (P > 0.05), except for the increase in serum glucose (P < 0.05). In conclusion, the optimal stage for harvesting and utilisation of MF is between 12 and 16 WAP and both MF and MSM, particularly the latter, are rich alternative protein sources for indigenous goats.

Background: Producing Thai native chickens through feed commercial is costly. To reduce the cost, native chicken could be fed with local plants or agricultural waste. Hyrrilla verticillate, a dominate macrophyte in Songkhla Lagoon, contain high crude protein and nitrogen free extract. Therefore, this research studied the use of Hydrilla verticillate in Thai native chicken diet on production performance, carcass characteristics and production cost. Methods: The experiment was executed in a completely randomized design (CRD) with 180 one-day-old commercial Thai native chicks. Four dietary treatments supplemented with 0%, 5%, 10% and 15% Hydrilla verticillata were formulated for three different phases of the experimental chickens: starter (1-4 weeks), grower (5-8 weeks) and finisher (9-12 weeks). Two chickens from each replicate were chosen for the carcass characteristics study. Result: During the starter phase, there was no notable effect shown among the chickens fed with the diet containing Hydrilla verticillata in terms of feed intake (FI) and body weight gain (BWG) (P greater than 0.05). The control chickens had best feed conversion ratio (FCR) (P less than 0.05), while the grower and the finisher periods, provided with different levels of Hydrilla verticillata, revealed no apparent differences (P greater than 0.05) concerning FI, BWG and FCR. Considering carcass characteristics, there were significant differences in live weight (LW) (P less than 0.05). But, no significant differences between treatments for hot carcass percentage, pectoralis majors, pectoralis minorstrip, thighs, wings, drumsticks and total edible carcass (P greater than 0.05). There were also statistical divergences regarding gizzard weight (GW) (P less than 0.05).

The purpose of the present study was to assess the effect of diets for market pigs with 20% inclusion of lupine seeds, cv. Amiga, on the performance, health status, carcass characteristics, fatty acids (FA) profile of meat lipids and nutritional and sensory parameters of meat. Another purpose was to increase the nutritional value of a cereal-lupine diet (E1) by supplementation with lysine, methionine, threonine (E2) or fat (E3) and to perform a comparison with control diets containing animal protein (C1) or soy (C2). The experiments were performed on 50 pigs (50% males, 50% females) with initial body weights of 35.6 &plusmn; 2.2 kg, fed isonitrogenic and isoenergetic diets partly <i>ad libitum</i> for 90 days. Feed intake was not adversely affected by lupine inclusion. The daily body weight gain (BWG) was significantly higher (<i>P</i> < 0.05) in group E3 in comparison with the cereal-lupine diet group (E1) and the other groups by 12.6 to 15.9% during the initial 30 days of experiment. The highest BWG (0.88 &plusmn; 0.07 kg/kg) during the entire experimental period was obtained with the fat containing diet (E3); that was non-significantly higher by 2.3 to 10.0% in comparison with the other diets. The feed conversion rate was reduced in groups E3 and E2 (2.55 and 2.58 kg/kg BWG) by 3.1 to 7.6% in comparison with groups C1, C2 and E1. No adverse effect of the lupine containing diet was observed on the carcass characteristics or the nutritional quality of the meat. Optimum content of linolenic acid in lupine seeds had a favourable effect on n-6/n-3 polyunsaturated FA ratio in meat lipids of group E3 in comparison with groups C1 and E1 (<i>P</i> < 0.05). By sensory meat analysis, significantly better characteristics were found for texture, juiciness (<i>P</i> < 0.01, <i>P</i> < 0.05) and taste in E3 in comparison with groups C1, C2 and E1. The obtained results indicate that animal and soy protein may be replaced with lupine, tested in the present study, in case a diet is supplemented with amino acids and fat.

Abstract Background The aim of this study is a comparison between some different protein sources in sheep rations to identify the best protein source that achieves the highest production performance and the lowest economical feed efficiency. Twenty Farafra male lambs weighed on average 41.39 ± 1.66 kg were divided randomly into four similar groups of 5 animals each. All groups were fed on concentrate feed mixture (CFM) at 3% of their body weight, and wheat straw fed ad lib. to replace 100% of the soybean meal (SBM) as a source of protein, black cumin seed meal (BCSM), cottonseed meal (CSM) and sesame seed meal (SSM) were incorporated into the CFM. The feeding trial extended for 66 days followed by digestibility and nitrogen (N) balance trials. Results The results indicated no difference in total feed intake between experimental groups. Digestibility of crude protein, ether extract and crude fiber for animals fed CSM ration was higher (p < 0.05) than those fed the other rations. On the other hand, the CSM ration recorded a higher value of digestible crude protein than SBM and BCSM rations. Lambs gave rations containing CSM was higher (p < 0.05) average daily weight gain compared with those fed the other rations. Lambs that fed CSM ration were better to feed conversion as kg dry matter intake/kg gain than those fed the other rations. Relative economic efficiency was the best for CSM ration as compared to other protein sources. Nitrogen balance value of sheep fed CSM diet had the highest (p < 0.05) value compared with those fed different sources. Rumen fermentation showed that the pH value was the lowest with SSM, NH3-N concentration was higher for BCSM and SSM, and total volatile fatty acids were higher for SBM compared with the other rations. Conclusion It could be concluded that cottonseed meal was the best treatment for digestibility coefficient, average daily gain, highest nitrogen balance, better feed conversion ratio and also the best economic efficiency compared to soybean meal, black cumin seed meal and sesame seed meal treatments. It can replace 100% soybean meal by cottonseed meal in sheep ration when economics is to be considered.

The effect of replacing an antibiotic growth promoter in the diet with a probiotic on growth performance, carcass characteristics and nutrient retention was studied in broilers (Vencobb 430) fed with and without meat cum bone meal (MBM). This experiment which lasted for 42 days consisted of six dietary treatments viz., basal diet (BD), basal diet with MBM (MBM), basal diet with antibiotic (AB), basal diet with probiotic (PB), basal diet with MBM and antibiotic (MBM+AB) and basal diet with MBM and probiotic (MBM+PB). Three-hundred, day-old chicks were randomly allotted in the beginning to these six groups. Body weight gain, feed intake and feed conversion ratio were significantly (P less than 0.05) affected at 4th week of age. Overall, highest body weight gain was recorded in birds fed with AB and PB. Inclusion of probiotic in MBM also showed improved body weight gain when compared to MBM group. Highest feed intake and feed conversion ratio was recorded with AB and PB groups. Birds supplemented with MBM+PB showed improved feed intake and feed efficiency when compared to MBM+AB and MBM diet supplemented groups. Higher dry matter, crude protein, calcium and phosphorus retention (P less than 0.05) was observed in birds supplemented with PB or AB in diet without MBM when compared to their control. In MBM supplemented groups addition of PB or AB improved crude protein retention. Birds supplemented with PB or AB with or without MBM showed a significant (P less than 0.05) increase in thigh yield and a non significant reduction in fat yield when compared to their control groups.

Probiotics are beneficial bacteria that had been used in poultry industry as alternative sources for antibiotic. The aim of this study was to determine the effect of probiotic mixed with cassava leaves (Manihot esculenta) on Cherry Valley Duck (Anas platyrhynchos domesticus) growth performance, carcass characteristics and meat quality. Lactobacillus spp. was used in this experiment to see its effectiveness in enhancing quality of cassava leaves as potential feed towards optimum growth performance of ducks like body weight gain, feed intake and feed conversion ratio, carcass characteristics and meat quality. 34 tails of Cherry Valley ducks aged 14 days with average weight of 500 g were randomly assigned to four treatments in triplicates. Treatments for the 35 days feeding trial were T1 at 0% probiotic + 75% commercial diet + 25% cassava leaves (control), T2 (0.15% probiotic + 75% commercial diet + 25% cassava leaves), T3 (0.30% probiotic + 75% commercial diet + 25% cassava leaves) and T4 (0.45% probiotic + 75% commercial diet + 25% cassava leaves) respectively. Proximate analysis was also conducted to determine nutritional content like protein, lipid, moisture, ash and fiber. Results show that supplementation of probiotic at 0.15% Lactobacillus spp. into 25% of cassava leaves and 75% commercial pellet gave highest body weight gain (BWG), low feed conversion ratio (FCR), highest carcass yield and good meat quality. It can be concluded that inclusion of probiotic at 0.15% in cassava leaves as duck’s diet gives good growth performance and may become an alternative super diet for duck in future.

Abstract. The effects of a probiotic (protexin), a medicinal plant (basil essential oil) and an antibiotic growth promoter (avilamycin) as broiler feed additives on performance, carcass characteristics and some blood parameters of broilers were studied. A total of 600 Arian broilers were divided into six treatments, with four replicates of 25 birds. Treatments were a plant essential oil in three levels (200, 400 and 600 ppm), the probiotic (150 ppm), the antibiotic (150 ppm) and a control group with no additives. Birds in different treatments received the same diets during the experimental period. Growth performance, blood biochemical parameters and carcass traits were measured. There were no effects of dietary treatment on body weight gain, feed intake and feed conversion ratio of the broilers. Internal organ weights and carcass characteristics were not influenced by treatments; however, 200 ppm basil essential oil supplementation decreased abdominal fat (P < 0.05). Biochemical parameters including serum low-density lipoprotein (LDL), high-density lipoprotein (HDL) and total cholesterol were not statistically influenced. However, addition of 400 ppm basil essential oil into diet increased serum triglyceride as compared to the control (P < 0.05). Results of this experiment demonstrated that the herbal natural feed additives such as basil may be used as alternatives to an antibiotic growth promoter without any adverse effects on broiler production.

Feeding Trial

This study was carried out to evaluate the growth performance and carcass characteristics of finisher broiler chickens fed diet containing cooked cocoyam tubermeal as energy source in place of maize. The proximate composition of cooked cocoyam tubermeal showed that it contained 13.11% moisture, 2.60% ash, 3.90% crude protein, 9.45% crude fiber, 1.85% ether extract and 70.13% NFE. In the finisher feeding trial, the cooked cocoyam tubermeal was used to replace maize at levels of 25%, 50%, 75% and 100% respectively in the control diet. Each finisher diet was fed to a group of 30 finisher broiler chicken for 4 weeks using completely randomized design. Each treatment was divided into 3 replicates of 10 broiler chicks each. The birds were kept on deep litter and were given feed and water ad-libitum. Parameters measured include ifinal body weight, body weight gain feed intake, feed conversion ratio, carcass characteristics and economics of production. In the finisher feeding trial, the feed intake of the finisher broilers on diets 2, 3 and 4 were similar and compared favourably with those on the control diet. The finisher group on 100% CCYM (diet 5) recorded the lowest feed intake possibly because of the dustiness of the feed. The body weight gain of the finisher broilers on diet 2 (25%) cooked cocoyam tubermeal compared favourably with the control group and was significantly (P<0.05) higher than those on other diets. It appeared that the finisher broilers could not tolerate high levels of cooked cocoyam meal due to dustiness of the feed and its anti-nutritional factors. The cost of production per kg finisher broilers was cheapest for diet 5(100% CCYM) (N356.72) and the costliest was for diet 3(50% CCYM) (N588.28). The internal organs expressed as percent of the live weight were not affected by the treatments. In terms of carcass characteristics, the finisher broilers on diet 2(25% CCYM) recorded the highest breast muscle which was significantly different (P<0.05) from other groups. There were no significant different (P>0.05) on percent back cut, drumstick, head, shank, thigh, neck and wings of the finisher broilers on all the treatments. There were no significant differences (P > 0.05) in percent dressed weight of the finisher broilers on cooked cocoyam based diets. The results of the trial have shown that cooking cocoyam corms (Xanthosoma sagittifolium) for 30 minutes was effective for reducing the cyanide oxalate, tannin, phytic acid and saponin content and that cooking did not affect the proximate composition of tannia. Cooked cocoyam tubermeal could be used to replace maize up to 25% in the diet of finisher broiler chicken without affecting body weight gain, feed intake and feed conversion ratio as indicated in this study.

A study was conducted to determine the comparative effect of feeding different levels of garlic and black cumin on growth, feed consumption, feed efficiency and carcass characteristics of Hubbard broiler. Two hundred fifty two Hubbard chicks having uniform body weight were randomly allocated into seven dietary treatments with three replications .The isoproteinous and isocaloric formulated standard starter, grower, and finisher diets were supplemented for 6 weeks with different levels of freshly ground dry garlic and black cumin seeds in order of T1-control, T2- 0.25% garlic, T3- 0.5% garlic, T4- 0.75% garlic, T5- 0.25% black cumin, T6- 0.5% black cumin, and T7- 0.75% black cumin, respectively. The results showed significantly higher cumulative weekly live body weight, body weight gain and feed conversion ratio for broiler fed diet supplemented with 0.5% garlic, followed by diet supplemented with 0.5% black cumin. There was no significant effect of different levels of garlic and black cumin supplementation in diet on carcass characteristics. Furthermore, there was minimum gross expenditure in broiler diet supplemented with 0.25% garlic and maximum in broiler diet supplemented with 0.75% black cumin. However, there was highest gross income and net profit in broiler diet supplemented with 0.5% garlic, followed by broiler diet supplemented with 0.5% black cumin. It is therefore, concluded that inclusion of garlic or black cumin in the broiler rations may be used for economical and efficient production of broilers.

The purpose of the present study was to ascertain whether it is possible to substitute animal protein in a pig diet with lupine of Sonet cultivar or amaranth grain or dried surface biomass of amaranth when one type feed ration is used during the entire period of fattening, and to investigate its impact on growth efficiency and health of pigs. Its role in feed conversion, carcass characteristics, meat quality and sensory parameters was analyzed. Four groups of pigs (n = 10, 5 males and 5 females) with the body weight of 24 kg were fed semi-ad libitum for 90 days the following diets: control group (C) - diet containing 3% of fish meal, experimental group (1) - diet containing 5% of non-heat-treated amaranth grain and 5% of dried surface biomass of amaranth, experimental group (2) - diet containing 5% of popped (heattreated) amaranth grain and 5% of dried surface amaranth biomass, experimental group (3) - diet containing 10% of lupine seed meal. Animal protein substitution in diets with amaranth (group 1, 2) or lupine (3) did not result in significant differences (p > 0.05) in average daily body weight gain in comparison with the control group (C - 0.83 and 0.82, 0.80 and 0.79 kg in groups 1, 2 and 3, respectively). The differences in feed conversion were non-significant (2.69 to 2.79 kg/kg of body weight gain). The tested diets did not adversely affect animal metabolism, and significantly lower concentrations (p < 0.05, p < 0.01) of total protein, glucose and triacylglycerol in animals of group C ranged within physiological limits. No significant differences between control and experimental animals were found in carcass characteristics, meat and sensory qualities. Lupine supplementation of the diet positively affected the tenderness and taste of meat.

Dietary Treatments

An experiment was conducted with commercial broilers to investigate the effects of feeding citric acid, acetic acid and their combination on their performance and to determine the economic competence of using citric acid and acetic acid in broiler rations. A total number of 108 one day old straight run broiler chicks were distributed to four dietary treatments i.e. 0 % citric or acetic acid (A), 0.5% citric acid (B), 0.5% acetic acid (C) and their combinations 0.5% citric acid and 0.5% acetic acid (D). The birds were reared in cages. Body weight gains, feed conversion ratio (FCR), mortality, dressing yield and carcass characteristics were recorded. The performance showed significant increase in body weight gain (P<0.05) when compared with the control during 0-5 weeks of age on 0.5% citric acid (B). Feed consumption increased (P<0.05) at 2nd and 3rd weeks of age on 0.5% citric acid (B). Feed conversion was found higher (P<0.05) during 0-5 weeks of age in treatment B when compared to those of the other treatments. Carcass characteristics were not affected by dietary treatments. The highest mortality was found in treatment A and treatment C due to excessive hot. It may be concluded that use of 0.5% citric acid in the diet of broilers may have better performance in respect of live weight gain and feed conversion.
