Dicalcium phosphate (DP) is a mineral involved in the metabolism and development and is used as a dietary source of phosphorus (PT) for poultry. Our study objective is to design nano-dicalcium phosphate (NDP) by co-precipitation. The methodological procedure was divided into two phases: (1) NDP synthesis, and (2) bird performance, digestibility, and Ca-P in chick’s tissues. The sizes of the NDP were 20–80 nm. NDP had the Ca: P ratio of 1:1.12. The birds were divided into control diet (available P (Pa) = 0.13%) and three supplementary P sources [Commercial (Calcium phosphate), analytical grade (DP) and nanoparticles (NDP)] with three Pa levels (0.24, 0.35, 0.46%). Supplementary P sources compared to the control treatment had the highest body weight gain (698.56 vs. 228; p < 0.05) and feed intake (FI) (965.18 vs. 345.82), respectively. The digestibility of PT (67%) improved with 0.35% NDP. The highest contents of PT -breast were with the levels of 0.35 and 0.46% NDP. The PT, ash, and diameters were higher (p < 0.05) with supplementary P compared to the control treatment. As conclusion, the use of 0.35% NDP was the ideal dose in the chicks for the digestibility, absorption values, and the amount of PT in the breast.

Present study was conducted to evaluate the different levels of energy to protein ratios (EPR) using food waste and black soldier fly larvae meal (FWBSFL) on growth performance and nutrient digestibility of broilers. A total of 160 one-day old broiler chicks were divided randomly to four groups and each group had 8 replicates with 5 chicks per replicate. The control diet was formulated using conventional feed ingredients with EPR of 154 for the starter period and 167 for the finisher period. The other treatments were diets with normal, low, and high EPR (154,143, and 166 for the starter period; 167, 155, and 177 for the finisher period) using FWBSFL. Feed consumption and body weight gain as well as digestibility of crude protein, crude fiber, and fat were decreased due to feeding of FWBSFL diets. Different levels of EPR using FWBSFL decreased growth performance and nutrient digestibility of broilers.

A total of 300 day old broiler chicks (Hubbard) were assigned to 30 floor pens (10 birds per pen) under cyclic heat stress. Three diets including a control, as well as two levels of grape seed powder (GSP) and zinc (OZ) at the rates of 2.5 g/kg GSP + 50 mg/kg OZ and 5 g/kg GSP + 50 mg/kg OZ, were supplied to the broilers for 35 days. According to the results, broiler feed intake improved (p < 0.05) in GSP + OZ groups from 3–5 weeks and on an overall basis compared to the control diet. Body weight increased (p < 0.05) in GSP-5 + OZ-50 during weeks 2–5 and on an overall basis. The findings indicated that feed conversion ratio (FCR) decreased (p < 0.05) during week 5 in broilers supplemented with GSP-5 + OZ-50. The antibody titer (HI) against Newcastle disease (ND) was higher (p < 0.05) in GSP + OZ groups compared to control treatment. The value of malondialdehyde (MDA) decreased (p < 0.05) under GSP + OZ diets compared to control. Moreover, paraoxonase (PON1) was higher (p < 0.05) in GSP + OZ groups compared to untreated broilers. In conclusion, GSP + OZ positively supported growth traits, reduced MDA, and augmented PON1 and HI titer against ND in broilers exposed to heat stress.

The effects of raw and autoclaved Shoti (Curcuma zedoaria) meal on the growth and N utilization of growing broilers were determined. Shoti from Bangladesh Agricultural University campus was collected and sorted on the basis of white color of the rhizome. Then they were chopped into pieces, sun dried and pulverized in a flour mill. Aliquot samples were autoclaved at 1200C under 15 lb of pressure per square inch for 30 min. Autoclaved samples were stored in tightly lid contained for future use. 3 One hundred -day-old Cobb 500 broiler chicks were reared on the floor and a total of 24 growing broilers, 4 birds in each group were weighed on d 15 Two broilers were placed in each cage. There were a total of four experimental and two control (positive and negative Non-protein control) diets. Diets were fed ad libitum from day 15 to 33days. Body weight, feed intake, feed refusal and fecal weights were recorded every day. Cumulative feed efficiency per bird was calculated as the ratio of weight gained to feed consumed. Dry matter of excreta was determined from the last 10 d of feeding trial by drying aliquots of every day’s droppings by drying for 6 h at 1050C. On d 19, birds were bled to death. Immediately after slaughter, the carcasses were examined systematically. The chemical composition of Shoti meal showed that it is low in protein, fat and trace minerals and therefore mainly a source of energy. The bulk of the tuber (75 percent) consists of carbohydrates, made up of 10.6% fiber, and 64.9% nitrogen free extracts (NFE). A peculiarity of Curcuma rhizome meal contains high level of ash (9.9%) on DM basis. The results showed that at day 33, the weight of the broiler chicken fed shoti 100g, 200g, 300 g and 200g (autoclaved shoti meal)/ Kg diet was significantly different from the weight of the chicken fed on a maize-soybean diet. The birds given shoti meal consumed less feed than those provided with a maize diet. Feed efficiency or weight gain to feed ration over 19-d period was the poorest when fed 300 g Shoti/ Kg diet. Intake picked up when the shoti meal was incorporated after having been autoclaved and there was slight improvement in body weight gain as compared to that of other Shoti fed group. However, feed efficiency and body weight gain as % of initial weight remained significantly lower than the maize-soybean control. The inclusion of Shoti meal generally had an adverse effect on the apparent dry matter digestibility compared with the control diets. The group fed autoclaved shoti meal had a similar effect and the true N digestibility was the lowest when compared to those of control fed on maize-soybean meal. Thus, physical treatment like using autoclave, caused further reduction of digestibility of its N. Lipid digestibility was reduced by ingestion of shoti meal. Since the diets were isocaloric, after correction for the apparent endogenous lipid losses, which were obtained from the results of non-protein control feeding, the net faecal losses was around 66.2% of the ingested lipid against control diet fed birds.

The present study aimed to assess the effect of dietary betaine (B) and/or creatine (C) on performance and thermoregulatory responses of broiler chicks. Indian River broiler chicks, fitted with compact thermosensors, were reared to market age (five weeks). The chicks were randomly distributed into four treatment groups, in a 2 × 2 factorial arrangement of treatments—basal control diet (Control group: CONT; B−/C−); 1 g betaine/kg feed (Betaine group: BETA; B+/C−), 1.2 g creatine monohydrate/kg feed (Creatine group: CRET; B−/C+), and combination (Betaine and Creatine group: COMB; B+/C+) of both supplements. At 31 days of age, 20 chicks from each group were exposed to acute heat stress (A-HS) for 3 h (34.45 ± 0.20 °C), and hemogramic profiles were screened before and after. Performance parameters (feed intake, body weight gain, and feed conversion ratio) were reported on a weekly basis, and carcass meat quality was evaluated at the end of experiment. Redness of breast was higher due to B and C treatments separately than the CONT group (B by C interaction; p < 0.05). Compared to the CONT, dietary supplements alleviated hyperthermia responses, with B alone being more efficient than C or COMB treatments. The mitigation of hyperthermia is likely mediated by enhancement of water balance indicators. Although not efficient in improving growth performance, dietary B and/or C are efficient in improving thermophysiological performance and survival of finishing broiler chicks under A-HS.

A nutrient retention and growth performance study were conducted with broiler chicks to evaluate the effect of different duration of fermented baobab seed meal (FBSM). Fermented baobab (Adansonia digitata) seeds were ground and incorporated in the diets at 12% dietary level. Diet 1 (control diet) had no BSM. Diet 2 had unfermented BSM. Diets 3, 4 and 5 had baobab seed meal (BSM) fermented for 48 h, 72 h and 96 h, respectively. Two hundred and forty (240) Arbor Acre chicks at one-week old were weighed and distributed to these dietary treatments. The five (5) treatments were replicated four (4) times in a completely randomized design, with 12 birds per replicate (48 per treatment). The diets did not significantly (p>0.05) influenced Feed intake, final body weight, feed conversion ratio and protein intake across treatments. The body weight gain and protein efficiency ratio of the chicks fed 96 h fermented BSM were not significantly (p>0.05) different with those fed control diet but were significantly (p<0.05) higher than chicks of other treatment groups. Starter broiler chicks fed T4 had significantly (p<0.05) higher nutrient digestibility parameters across treatments, except for EE and CF that were highly digested by chicks fed T3 and T1 respectively. In conclusion the performance of broiler chicks fed 96 h FBSM competed favorably with those fed control diet, whereas, chicks placed on 72 h FBSM recorded better result of nutrient digestibility.

An experiment was conducted for a period of 56 days with 36 healthy New Zealand White (NZW) rabbits aged about one months having weight from 370 to 390g to evaluate the effects of dietary citric acid on growth performance, feed consumption and digestibility of nutrients as well as immune status. The experiment was designed with 6 dietary treatments having 6 rabbits per treatment. Rabbits of control treatment (T1) were given the diet without citric acid (CA) but the dietary treatments T2, T3, T4, T5 and T6 contained 0.5, 1.0, 1.5, 2.0 and 2.5% CA respectively. Green grass was supplied on ad libitum basis. The total body weight gain was Addition of CA at the level of 2% enhanced body weight significantly (P<0.05). (P<0.05)(P<0.05) T 734, 776, 812, 862, 911 and 740g for the rabbits fed 0, 0.5, 1.0, 1.5, 2.0 and 2.5% CA containing diets respectively. Total DM intake also increased with increasing the percentage of CA up to 2% level . Incase of feed conversion ratio, there was no significant difference in addition to different levels of CA. Supplementation of CA improved dry matter, crude protein and ether extract digestibility but incase of crude fiber and nitrogen free extract, there was no significant difference. Non significant difference was also found incase of acidity of feed and feces. The highest lymphocyte (73%) was counted in dietary treatment T6 having 2.5% CA, which was 17% higher than the control diet. From the result of this experiment, it may be concluded that the addition of CA up to 2% level in diet improves performance, digestibility of nutrients and immune status of growing rabbit.

The study was conducted to determine the efficacy of organic Se produced through Saccharomyces cerevisiae from sodium selenite in the diet of Vanaraja and commercial broiler chicken. The trial was conducted in day-old Vanaraja chicks (n=160), which were randomly distributed into 4 dietary groups having 5 chicks in each of 8 replicates. The basal diet (BD) was formulated and supplemented with calculated quantity of organic Se to formulate the different experimental diets and fed up to 5 weeks. The second experiment in day-old commercial broiler chicks (n=350), which were randomly distributed into 7 dietary groups having 5 chicks in each of 10 replicates. The experimental birds were fed BD (diet I) with 0.2 mg/kg organic Se (diet II), 0.4 mg/kg organic Se (diet III) and 0.6 mg/kg organic Se (diet IV), and BD with 0.2 mg/kg inorganic Se (diet V), 0.4 mg/kg inorganic Se (diet VI) and 0.6 mg/kg inorganic Se (diet VII) up to 6 weeks. The body weight gain during 5th week was higher (P Lass Than 0.05) in the birds fed with diet supplemented 0.3 mg/kg of the organic Se compared to the other groups. However, feed intake and feed conversion ratio (FCR) among different groups did not vary (P>0.05) throughout the experiment. The activity of glutathione peroxidase was higher (P Lass Than 0.01) among the groups fed the diets containing organic Se (0.2, 0.3 and 0.4 mg/kg) compared to the control diet in experiment I. In experiment II, body weight gain and FCR at the end of the experiment were improved significantly (P Lass Than 0.01) in the group fed 0.2 mg/kg organic Se compared to control. Alanine transaminase, Aspartate aminotransferase, triglycerides and cholesterol levels were lower in groups fed diets supplemented organic Se compared to control or inorganic Se fed groups. Whereas, glutathione reductase activity was significantly higher among the groups supplemented organic Se compared to other dietary groups. Based on the results it can be concluded that supplementing organic Se up to 0.3 mg/kg enhanced the body weight gain and anti-oxidant enzyme activity in Vanaraja and commercial broiler chicken.

The present study 180, day-old broiler chicks (Vencobb) were randomly distributed into 3 treatment groups with three replicates in each group. The chicks were placed in 9 pens with 20 chicks in each pen and reared in deep litter system under uniform management conditions. Control starter (0-3 wk) and finisher (4-6 wk) diets were formulated to meet the entire nutrients. Subsequently two test diets were prepared by incorporating acid treated fish silage at 5 and 10% level. Each diet was offered ad libium to 3 pens of 20 chicks each throughout the experimental period (0-6 wks). Dietary incorporation of acid treated fish silage up to 10% had no influence on body weight gain and feed consumption of broilers. The feed conversion ratio improved significantly by incorporation of fish silage at both 5 and 10%, during starter phase, but no influence was noticed subsequently. Fish silage up to 10% in the diet did not affect the dressed percentage and relative weight of other carcass parameters such as liver, heart, gizzard, breast and abdominal fat. The albumin to globulin ratio increased significantly (P>0.05) due to incorporation of fish silage at 10% in the diet compared to that of control. The serum triglyceride concentration increased significantly (P>0.05) at 10% level of inclusion of fish silage in diet. Lowest cholesterol concentration was found in the dietary group fed the control diet. The serum cholesterol concentration increased significantly (P>0.05) and linearly by increasing the level of fish silage from 5 to 10%. It is concluded that acid treated fish silage can be incorporated upto 10% in the diet without any adverse effect on performance of broiler chickens.

Conventional feed resources for livestock are increasingly becoming more expensive, due to competition with man; hence nutritionists are searching for cheaper, locally-available alternatives. A total of forty-five (45) mixed sex weaner rabbits, aged 5 – 6 weeks, with average initial weights of between 694.42 and 761.10 g were used to investigate the effect of varying levels of cowpea milling waste (CMW) diets on their growth performance and nutrient digestibility. They were randomly allotted to five dietary treatments with nine rabbits per treatment. The control treatment (T1) contained 0 % CMW while treatments T2, T3, T4 and T5 had 10, 20, 30 and 40 % CMW dietary inclusion levels, respectively. Clean water and feed were offered ad libitum daily to the rabbits, and record of their feed intake and growth performance were taken for 12 weeks. At the end of the 11th week, a nutrient digestibility trial was carried out. Results show that there were no significant (P>0.05) differences in final body weight, body weight gain, total feed intake and mortality among the dietary treatments. Feed conversion ratio (FCR) for diets T4 (6.65) and T5 (6.66) containing 30 and 40 % CMW respectively, were as good as that of the control diet (6.11). Dry matter and crude protein digestibility showed no significant (P>0.05) difference across the treatments. Digestibility of crude fibre (72.64, 80.16, 84.04 and 80.90 % for T2, T3, T4 and T5 respectively), ether extract (95.98, 94.90, 96.04 and 94.38 % for T2, T3, T4 and T5 respectively), nitrogen free extract (94.30, 95.18, 93.58 and 94.90 % for T2, T3, T4 and T5 respectively), as well as total digestible nutrient (83.69, 76.11, 81.67 and 80.02 % for T2, T3, T4 and T5 respectively) of the test diets compared favourably with that of the control diet (72.94, 95.23, 96.04 and 80.47 % for CF, EE, NFE and TDN respectively). Hence, it can be concluded that CMW can be used safely as a protein source and included up to 40 % in weaner rabbit diets with no detrimental effect on their growth performance and nutrient digestibility.
