The Huanjiang mini-pig is a Chinese local breed and, the optimal dietary crude protein (CP) level for this breed is still unknown. Therefore, the present study was conducted to investigate its optimum dietary CP level upon the growth performance, serum biochemical parameters, fecal nitrogen content, and carcass traits. Three independent trials with 360 pigs were included. A total of 220 pigs (5.32 ± 0.46 kg) were fed ad libitum, either a 14, 16, 18, 20, or 22% CP diet from about 5- to 10-kg (trial 1); 84 pigs (11.27 ± 1.43 kg) were fed either a 12, 14, 16, 18, or 20% CP diet from about 10- to 20-kg (trial 2); and 56 pigs (18.80 ± 2.21 kg) were fed either a 10, 12, 14, 16, or 18% CP diet from about 20- to 30-kg (trial 3). In trial 1, as dietary CP levels increased, the feed-to-gain ratio (F/G) quadratically decreased (p < 0.05) and was minimal at the 18.42% CP level. The average daily feed intake (ADFI) and final body weight (BW) were not affected by dietary CP levels while the fat percentage decreased (p < 0.05). Besides, a linear decrease in slaughter rate (p = 0.06) and a linear increase in bone percentage (p < 0.05), serum urea nitrogen (UN) (P < 0.05), and fecal nitrogen content (p = 0.07) of pigs were observed. In trial 2, as dietary CP levels increased, the average daily gain quadratically increased (p < 0.05) and was maximum at the 16.70% CP level. The slaughter rate linearly decreased (p < 0.05) whereas the skin rate, serum UN, and NH3-N increased (p < 0.05) linearly, as well as fecal nitrogen content (p = 0.06). In trial 3, as dietary CP levels increased, the F/G increased (p < 0.05), while the ADFI and ADG quadratically decreased (p < 0.05) and was maximum at nearly 14.00% CP level. The bone percentage and serum UN increased (p < 0.05) linearly but the slaughter rate decreased (P < 0.05) linearly, and the fecal nitrogen content quadratically decreased (p = 0.07) whereas the albumin increased (p < 0.05) quadratically. Taken together, the optimal dietary CP levels for growth performance of Huanjiang mini-pigs from 5- to 10-kg, 10- to 20-kg, and 20- to 30-kg were 18.42, 16.70, and 14.00%, respectively.

Background and Aim: Garcinia kola seed (GKS) is used to prevent and cure a number of gastric-related ailments. GKS contain a copious amount of polyphenols and can be utilized as a natural growth promoter in the nutrition of weaned rabbits. This study aimed to determine the dietary effects of GKS meal (GKSM) on the growth performance, hematology and serum biochemical parameters of weaned rabbits. Materials and Methods: GKS were dried and ground into powder. Thirty-two 8-week-old crossbred rabbits with an average weight of 614 g were randomly divided into four dietary groups. The diets were designated as follows: Control (corn-soybean based diet with 0% GKSM) and the GKSM-supplemented diets with 1.5% GKSM, 3% GKSM, and 4.5% GKSM. On the 56th day of the feeding trial, blood was collected from the marginal ear vein of all rabbits and transferred into two separate labeled tubes. The first set of blood was used to determine the hematological indices. The second set of blood was transferred into plain bottles and allowed to coagulate. The coagulated blood was subjected to standard methods of serum separation, and the sera were harvested and used to evaluate serum biochemical parameters. Results: Although the average final body weight was highest in rabbits fed with 1.5% GKSM; this value was similar to rabbits fed with 0% and 4.5% GKSM. The average daily weight gain was highest in rabbits fed with 1.5% GKSM, while the feed conversion ratio was improved in the 0% and 1.5% GKSM groups. The dietary treatments also had a significant effect on the red blood cell count (RBC) and hemoglobin (Hb) concentration, while other blood parameters did not differ significantly (p>0.05). Higher inclusion levels (3% and 4.5%) of GKSM led to a significant increase in RBC and Hb values (p<0.05). The total protein increased at all levels of GKSM inclusion (p<0.05). Bilirubin, sodium, and potassium levels significantly decreased at 4.5% GKSM inclusion (p<0.05). Urea levels were lowered at 1.5% and 4.5% GKSM inclusion, while cholesterol levels were decreased at 3% and 4.5% dietary levels. Conclusion: From the results of the present study, the supplementation of up to 4.5% GKSM revealed no harmful effect on the hematological and serum biochemical parameters of weaned rabbits, while their growth performance improved at a 1.5% inclusion level of GKSM.

Abstract Background: Cottonseed meal (CSM), a relatively rich source of protein and amino acids, is used as an inexpensive alternative to soybean meal (SBM) in poultry diets. Two experiments were conducted to investigate the effects of CSM on growth performance, liver redox status, and serum biochemical parameters in goslings. In experiment 1, 300 1-d-old male goslings were randomly divided into 5 groups (10 goslings/replicate, 6 replicates/group) and subjected to a 28-d experiment. In experiment 2, 240 28-d-old male goslings were randomly divided into 5 groups (8 goslings/replicate, 6 replicates/group) and subjected to a 35-d experiment. Five isonitrogenous and isoenergetic diets were formulated to produce diets in which 0% (control), 25% (CSM25), 50% (CSM50), 75% (CSM75), and 100% (CSM100) of protein from SBM was replaced by protein from CSM.Results: In experiment 1, dietary CSM was associated with linear decreases in body weight, average daily feed intake and average daily gain and linear increases in the feed-to-gain ratio and mortality from 1 to 28 d of age (P < 0.05). Increased dietary CSM was associated with linear decreases in the hydroxyl radical scavenging ability and superoxide dismutase, catalase and glutathione peroxidase activities in the liver (P < 0.05). Dietary CSM was associated with linear decreases in serum total protein, albumin, and globulin concentrations and linear increases in serum uric acid concentrations (P < 0.05). In experiment 2, the growth performance from 29 to 63 d, redox status indicators (except for malondialdehyde [MDA]) in the liver, and serum biochemical parameters at d 63 were not affected by dietary CSM concentrations (P > 0.05). The MDA content in the liver in the CSM100 group was lower than those in the other four groups (P < 0.05).Conclusion: CSM in gosling diets should not exceed 7.08% in the early growth stage (d 1 to 28), but it can be increased to 22.65% from d 29 to 63. A high concentration of CSM may reduce growth performance in 1- to 28-d-old goslings due to decreases in feed intake, liver metabolism and antioxidant capacity.

This study aimed to investigate the effects of Bacillus amyloliquefaciens LFB112 on the growth performance, carcass traits, immune response, and serum biochemical parameters of broiler chickens. A total of 396 1 day old, mixed-sex commercial Ross 308 broilers with similar body weights were allotted into six treatment groups. The assigned groups were the CON group (basal diet with no supplement), AB (antibiotics) group (basal diet + 150 mg of aureomycin/kg), C+M group (basal diet + 5 × 108 CFU/kg B. amyloliquefaciens LFB112 powder with vegetative cells + metabolites), C group (basal diet + 5 × 108 CFU/kg B. amyloliquefaciens LFB112 vegetative cell powder with removed metabolites), M group (basal diet + 5 × 108 CFU/kg B. amyloliquefaciens LFB112 metabolite powder with removed vegetative cells), and CICC group (basal diet + 5 × 108 CFU/kg Bacillus subtilis CICC 20179). Results indicated that chickens in the C+M, C, and M groups had higher body weight (BW) and average daily gain (ADG) (p < 0.05) and lower feed conversion ratio (FCR) (p = 0.02) compared to the CON group. The C+M group showed the lowest abdominal fat rate compared to those in the CON, AB, and CICC groups (p < 0.05). Compared to the CON group, serum IgA and IgG levels in the C+M, C, and M groups significantly increased while declining in the AB group (p < 0.05). B. amyloliquefaciens LFB112 supplementation significantly reduced the serum triglyceride, cholesterol, urea, and creatinine levels, while increasing the serum glucose and total protein (p < 0.05). In conclusion, B. amyloliquefaciens LFB112 significantly improved the growth performance, carcass traits, immunity, and blood chemical indices of broiler chickens and may be used as an efficient broiler feed supplement.

This study investigated the genetic variation in carcass traits and blood parameters of local naked neck and normal-feathered chickens and their crosses with Marshall broiler chickens. Two hundred and sixty three chickens consisting of 50 purebred Marshalls (M), 38 naked neck (Nk) and 48 normal-feathered (N), 61Marshall x naked neck (MNk) and 66Marshall x normal-feathered(MN) chickens were used for the study. Data were collected on carcass traits, haematology and serum biochemical parameters and were analysed using the General Linear Model procedure of Statistical Analysis System. Carcass traits such as eviscerated weight and weights of thigh, drumstick, breast, wings and organs were significantly (P < 0.0001) affected by genotype. Results showed that the purebred Marshall had the highest values in most of the traits followed by their crossbreds. In organs such as gizzard, liver and heart the local normal feathered ranked equal with its crossbred. Sex significantly (P< 0.05) affected carcass traits. Males consistently had higher values than females in all the parameters measured. Genotype significantly (P
