The therapeutic use of vitamin D3 and strontium has been successful for the treatment of osteoporosis in humans; however, the value of similar strategies in poultry is not clear. Male Ross broiler chicks (n = 216) were used in a 28-day broiler trial to assess effects of vitamin D3 and strontium supplementation on performance, nutrient retention, bone composition, and bone mass. Treatments included an industry-standard control diet and five additional diets where vitamin D3 was added at 5000, 20 000, or 35 000 IU/kg and strontium was added at 0 or 1200 mg/kg in a 3 × 2 factorial design. Broiler chickens supplemented with strontium and additional vitamin D3 did not increase bodyweight; however, there was a significant improvement in feed efficiency at medium levels of vitamin D3, and although not statistically significant, there was also an improvement in feed conversion ratio with strontium supplementation at normal vitamin D3 concentrations. Strontium supplementation at normal levels of vitamin D3 significantly (P < 0.01) increased calcium, phosphorus, sodium, potassium, and magnesium retention. A high concentration of vitamin D3 produced a significant improvement in apparent metabolisable energy, protein, and dry matter utilisation in the broiler chicken. Paradoxically, however, there was a detrimental effect of high vitamin D3 on bodyweight and feed efficiency, which was partially ameliorated by strontium supplementation. Strontium addition did not change bone mass but did change bone composition. High levels of vitamin D3 significantly (P < 0.01) reduced bone ash content and increased strontium content of bone. In conclusion, both vitamin D3 and strontium have the potential to positively influence the performance, mineral retention, and bone characteristics of broiler chicks. However, as with calcium and phosphorus, vitamin D3 and strontium interact and so more research is required with strontium on the optimum dose rate and its relationship with vitamin D3, calcium, phosphorus, and IGF-1 in broiler nutrition.

Background: In Vietnam, animal feed mainly depends on imported raw materials, while available agro-industrial by-products are often released into the environment and only a its unsubstantial portion used as an animal feed. Therefore, efficient use of these by-products as animal feed is essential. This work aimed to evaluate the effect of dietary levels of rice distiller’s dried grain (Rice DDG) on broiler performance, meat yield and meat quality. Methods: The research was conducted at the experimental station, Vietnam National University of Agriculture, Vietnam, from May to September 2020. A total of 240 a day-old broiler chicks were randomly assigned into 4 groups with 3 replications to receive 4 diets with different levels of RDDG at 0, 5, 8 and 10% for 14 weeks. Growth, meat yield and meat quality were estimated. Result: ADG was higher in broiler chickens fed diets with rice DDG compared to that in control diet at 12 and 14 weeks (P less than 0.05) while ADFI and FCR were not affected by the diets. There were significantly no differences in meat yield and quality among the diets. In conclusion, rice DDG could be used to partially replace main ingredients in chicken diets.

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.

Purpose of researches in feed restriction area is improvement of feed efficiency, decrease of carcass fat content and abdominal fat pad size (Plavnik and Hurvitz,1991).Birds after early life feed restriction have less maintenance requirements due to decrease of heat increment and decrease of basal metabolic rate and specific dynamic action of food (Forsum et al.,1981).In many investigations, compensatory growth have not observed (Summers et al.,1990).It seems administration of Thyroid hormone after feed restriction can induce compensatory growth. The objective of the present study was to investigate the effect of early feed restriction and L-Thyroxin administration after early feed restriction on compensatory growth in broiler chickens.

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 influence of feeding with starter diets containing spray-dried bovine colostrum (SBC), spray-dried bovine plasma (SBP), or spray-dried porcine plasma (SPP) on the growth performance and gut morphology of broiler chickens was investigated. The crude protein, lysine, and methionine plus cystine contents (g/kg as received) of SBC, SBP, and SPP were determined to be 766, 736, and 684; 58, 61, and 55; and 27, 28, and 24, respectively. The 3 test proteins were incorporated into a maize–soybean meal diet at a level of 50 g/kg and fed to 6 replicates of 8 male broiler chicks from 1 to 14 days of age. On Day 14, the experimental diets were replaced with a common grower-finisher diet, which was offered until Day 35. Dietary treatments had no effect (P > 0.05) on the weight gain or feed intake of birds during the first 14 days. However, feed/gain of birds fed the SBC diet was lower (P < 0.05) than of those fed the control diet. A trend for a reduction in feed/gain (P = 0.06) was observed in SBP and SPP diets. Dietary treatments had no effect (P > 0.05) on performance during Days 14–35 or Days 1–35. Villus height was increased by 5.7% (P < 0.05) and 4.6% (P = 0.05) in birds fed the SPP and SBP diets, respectively, compared with those fed the control diet. Crypt depth was 6% greater (P < 0.05) in birds fed the SPP diet and tended (P = 0.08) to be greater in birds fed the SBC diet, compared with birds fed the control. The ratio of villus height to crypt depth tended (P = 0.06) to be lower in birds offered the SBC diet compared with the control. Crypt goblet cell density was reduced (P < 0.05) by 13.9% in birds fed the SBC diet, compared with control birds. These results suggest that feeding with diets containing the SBC, SBP, and SPP during 1–14 days of age has some beneficial effects on broiler chickens. Further studies are needed to evaluate these products in less sanitary environments, which may increase the positive responses.

One hundred ninety-two male broiler chicks were dosed with monensin at concentrations of 0, 121, or 242 mg/kg feed throughout the normal growing period (50 days). Body weight gain and feed efficiency were determined weekly, and cardiac muscle was examined grossly and histologically at the end of the experiment. Livers also were weighed and examined grossly. Feed intake was determined daily, allowing continuous monitoring of drug intake. No depressing effects of the drug on growth rate and efficiency were observed until after four weeks, and then were evident only in the chicks receiving the 242 mg/kg diet. Subepicardial hemorrhage and congestion occurred in 40% of the hearts from the chickens fed the high monensin dose and were nonexistent in the other treatments. There appeared to be an inverse relationship between monensin dose and liver weight. The paralytic effects previously reported from acute dosing experiments were not observed. The results show that the heart and probably the liver are sensitive indicators of monensin toxicity and that the subchronic toxic dose is less than 18 mg/kg body weight per day.

Two experiments were conducted to investigate the effects of supplementing broiler diets fed to 6 wk of age, with 0, 10, 20 or 30% of commercially heated unextracted soybeans (T.I.A. 3.9 mg g−1). Birds fed soybeans consumed less feed in the 0- to 21-d starter period and this was associated with reduced weight gain (P < 0.05) and increased feed intake: weight gain (P < 0.05). There was a decrease in calcium, phosphorus, magnesium and fat retention with feeding of soybeans and this effect was most pronounced with the 30% inclusion level. Diet ME was also reduced with increased use of soybeans (P < 0.05). However, there was a decrease in digesta and fecal soap concentration with an increase in dietary levels of heated ground soybeans (P < 0.01). While carcass weight followed a trend similar to that of weight gain (P < 0.01), there was no difference between treatments for percent carcass yield (P < 0.05). Soft fat depot areas were observed when soybean oil was the primary dietary fat. Fatty acid analysis of carcass fat confirms a high degree of unsaturation for birds fed 30% heated soybeans. However, this feature was not unduly objectionable nor did it affect carcass grading (P > 0.05). Key words: Heated soybeans, broiler performance, carcass quality

Feeding trial experiment was carried out to evaluate the haematological and serum biochemical parameters of broiler chickens fed graded levels of Roselle Seed Cake (RSC) as replacement of a conventional protein source. Proximate composition was done to determine the nutrient content of RSC and experimental diets. The experiment contained graded levels of RSC replacing soya bean cake (SBC). One hundred and twenty (120) day old Ross broiler chickens were used in a Completely Randomized Design (CRD). The broiler chicks were assigned to five dietary treatments with three replicates each with 8 birds per replicate and 24 birds per treatment. Five isonitrogenous and isocaloric diets were formulated for the broiler straight diet. Diet 1 served asthe control diet while diets 2, 3, 4 and 5 contained 8%, 16%, 24% and 32% RSC respectively. Data were collected and analyzed using analysis of variance and the mean was separated using Duncan multiple range test. The findings from the study showed that there were no significant (P?0.05) differences in all the parameters measured for haematology across dietary treatment means except for the white blood cell. The blood biochemical composition showed no significant (P?0.05) differences in total protein, high density lipoprotein, low density lipoprotein and creatinine across dietary treatments. RSC as an alternative feedstuff can replace soya bean cake at 24% in the diet of broiler chickens for improved haematological and blood biochemical of broilers. Roselle seed cake can replace SBC at the broiler chicken straight ration at 75% (24% dietary RSC) inclusion for better performance.

An experiment was conducted to compare the haematology and some serum constituents and performance of broilers fed diets containing improved (addition of anti-microbial and anti-oxidant) locally produced natural vitamin premix (LPNVP), LPNVP without improvement and commercial vitamin premix (CVMP). Haematology of the birds was not affected by the dietary treatments. However, red blood cell (RBC) count was significantly high (P<0.05) for the birds fed diet containing improved LPNVP The haemoglobin, PCK, RBC and WBC values observed for birds fed improved LPNVP were 13 gm%, 32%, 246 x 1012/L and 3.1 x 1010/L respectively. Serological parameters observed in the study were not significantly different (P>0,.05) for all the dietary conditions studied. Birds fed diet containing improved LPNVP also recorded comparable serum components to control diet containing the commercial vitamin/’mineral premix. Serum calcium, phosphorus, glucose, ureate, creatinine and total protein observed for birds fed diet containing improved LPNVP were 2.32%, 0.70%, 3.60Mmo/L, 2.9Mmo/L, 0.25Mmol/L, 58Mmol/L and 66g/100ml respectively. Feed intake, weight gain and feed utilization were similar (P>0.05) for the various dietary treatments. Birds fed improved LPNVP based diets tended to record better feed intake than did the control birds on CVMP based diets and unimproved LPNVP. Generally, improvement of LPNVP tended to give better performance of broilers than did other dietary treatments.

The residue originated from antibiotics and hormones had been thought to carry out adverse effects for the human who consume meat processed from the broilers treated by antibiotic feed additive. For this reason, using an alternative additive such as probiotic might produce healthier meat. The objective of the recent study was to evaluate administering different levels of probiotic yakult + tape yeast (YTy) into the mixing of rice bran + corn bran (RCB) to replace 30% of the commercial diet to carcass yield and abdominal fat of broilers. As many as 100 broiler chicks, Cobb strain, were reared up to 5 weeks in this study. The study was designed into a Completely Randomized Design with subsampling consisted of 5 treatments, 4 replications, and 2 sub samples. Broiler commercial diet with the market code of CP 511 Hi-provite manufactured by PT Charoen Pokphand was used for a positive control diet (P0+). The RCB feeds were mixed with 0, 10, 20, and 30 ml/kg of probiotic YTy then being used to replace 30% of the commercial diet to build experimental diets P0-, P1, P2, and P3, respectively. The results of the recent study indicated that administering 10‒30 ml/kg of probiotic YTy highly significantly (P<0.01) increased the weights of the whole carcass and carcass parts. The percentages of whole carcasses among P1, P2, and P3, however, were not statistically different. The percentage of the breast significantly (P<0.05) increased while the percentage of the back significantly (P<0.05) decreased. Although statistically not significant differences, the abdominal fat percentage tended to decline. In conclusion, administering a probiotic YTy in the diet increased the percentage of the whole carcass and tended to reduce the abdominal fat of the broiler.
