The objective of this study was to evaluate the performance of calves (Holstein × No Defined Breed Standard) fed powdered cheese whey associated with discarded powdered milk up to 60 days of age. Forty calves (35 kg initial average weight) were used, distributed in a completely randomized design with four treatments and ten repetitions per treatment: whole milk (control), 100% milk powder, 80% milk powder + 20% cheese whey powder, 60% milk powder + 40% cheese whey powder. Consumption, performance, and economic analysis were evaluated. Data were analyzed for variance and comparison of orthogonal contrasts (P < 0.05). No significant differences were observed between the treatments tested regarding the evaluated variables. The animals from all treatments had a final average weight of 50.28 kg as the result of an average weight gain of 0.255 ± 0.03 kg/day and a total dry matter intake of 34.28 ± 1.47 kg/day per calf. The examined diets offered the lowest cost compared to the control treatment, generating an average additional profit of 113.19 R$/animal. Diets containing whey cheese powder are the most economically advantageous options, as replacing 100% of milk with these by-products did not impair animal performance. The use of discarded industrial milk powder combined with whey powder in a ratio of up to 80:20 is a viable option for feeding male calves in dairy farms.

The objective of this study was to evaluate the effect of powdered cheese whey and milk powder as a substitute for whole milk on rumen development in calves up to 60 days of age. Twenty-one-week-old Holstein-Gir crossbred calves were randomized across four treatments and six replicates: LI: whole milk (Control); LP: milk powder; LPS1: 80% milk powder + 20% cheese whey powder; LPS2: 60% Milk Powder + 40% Cheese Whey Powder. The animals were slaughtered at 60 days of age. The consumption, weight of stomach and its compartments, ruminal papilla height, and rumen proliferative activity were measured. Dry matter intake, absolute and relative weights of the gastric compartments were similar. Significant differences were found in the development of rumen papillae and the mean height of the ventral sac was higher in the animals that received whole milk. There were no significant differences for cell proliferation rate in rumen papillae. It is suggested that feeding calves whey with powdered milk may be a viable alternative to the use of whole milk without harming dairy calves.

Abstract A collaborative study involving 19 laboratories was performed to validate motility enrichment on modified semisolid Rappaport-Vassiliadis (MSRV) medium for rapid detection of motile Salmonella in dried milk products. The MSRV method was compared with the AOAC culture method for detection of Salmonella in nonfat milk powder, whole milk powder, whey powder, casein powder, and butter milk powder. Samples were artificially inoculated with Salmonella at 2 levels of contamination. Un-inoculated control samples were included for each type of product. The sensitivity rates were 100% for the MSRV method and 99.0% for the AOAC culture method, while the specificity rate was 100.0% for both methods. Only for the samples of whey powder, which were inoculated with H2S negative S. tennessee, was there a significant difference in the proportion of samples positive by MSRV and the culture procedure. The MSRV method for detection of motileSalmonella in dried milk products has been adopted first action by AOAC INTERNATIONAL.

ABSTRACT: This research was performed to ascertain the most suitable Artificial Neural Network (ANN) model to quantify the degree of fraud in powdered milk through the addition of powdered whey via regular standard physicochemical analyses. In this study, an evaluation was done on 103 samples with different quantities of added whey powder to whole milk powder. Using Fourier Transform Infrared Spectroscopy the fat, cryoscopy, total solids, defatted dry extract, lactose, protein and casein were analyzed. The hyperbolic tangent transformation function was used with 45 topologies, and the Holdback and K-fold validation methods were tested. In the Holdback method, 75% of the database was employed for training, while 25% was used for validation. In the K-fold method, the database was categorized into five equal sized subsets, which alternated between training and validation. Of the two methods, the K-fold method was proven to have superior efficiency. Next, analysis was done on three models of multilayer perceptron networks with feedforward architecture. In Model 1, the input layer contained all the physicochemical analyses conducted, in model 2 the casein analysis was excluded, and in model 3 the routine analyses performed for dairy products was done (fat, defatted dry extract, cryoscopy and total solids). From Model 3 an ANN was derived which could satisfactorily predict fraud calculated from using the routine and standard analyses for dairy products, containing 64 nodes in the hidden layer, with R2 of 0.9935 and RMSE of 0.5779 for training, and R2 of 0.9964 and RMSE of 0.4358 for validation.

This study aims to determine the effect of noni leaf (Morinda citrifolia lignosae) extract as a natural disinfectant on the percentage of hatchability and the hatchability weight of quail (Coturnix-coturnix japonica). This study used 1,500 quail hatch eggs with a male and female parent ratio of 1: 4. This study used a Completely Randomized Design (CRD) method, with five treatments and three replications each repetition consisting of 100 quail eggs with 10-gram weight. The treatments used were: T0 (control treatment), T1 (commercial disinfectant), T2 (noni leaf extract 10%), T3 (noni leaf extract 20%) and T4 (noni leaf extract 30%). The results of variance showed the average percentage of hatchability produced during the study, namely T0 (85%), T1 (83%), T2 (86%), T3 (84%), and T4 (93%). Furthermore, the average weight of hatchability produced, namely T0 (6.67 grams), T1 (6.76 grams, T2 (6.89 grams), T3 (6.84 grams) and T4 (6.89 grams). Overall administration of noni leaf extract had no significant effect (P> 0.05) on the percentage of hatchability and DOQ hatching weight of the quail.

ABSTRACT: This study aimed to evaluate whether cheese whey associated with transitional milk or not, could serve as a suitable alternative to whole milk for calf rearing. For this, twenty-four male calves of crossbred Holstein-Zebu, were distributed in a completely randomized design with three treatments (8 calves per treatment) and fed for 60 days with one of the following liquid diets: i) 100% whole milk, ii) 50% whole milk and 50% cheese whey, and iii) 30% transitional milk and 70% cheese whey. There was no difference in food intake between treatments. The analysis showed that whole milk replacement did not alter the stomach weight or the ruminal cell proliferation when compared to treatment using 100% whole milk; however, the transitional milk/cheese whey group showed larger ruminal papillae. These results suggested that a transitional milk-cheese whey diet associated with solid food and proper nutrient complements might enhance the post-natal development of rumen papillae in calves, which might contribute to prepare them for weaning.

ABSTRACT The attack of Aeromonas hydrophila bacteria can cause mortality in goldfish approximately 100%. The controlling of this bacterial attack can be done through increased fish immunity. Honey is one of the natural ingredients that increases body immune system. This study aimed to determine the effective dose of honey supplemented in feed to increase goldfish fingerling resistance for disease prevention. Fish used in this study were goldfish fingerlings with 3.5 g average weight. This study was done using experimental complete randomized design method with five treatments and three replications. Treatments given were honey supplementation in feed with 0 ml/kg (A) as control treatment, 150 ml/kg (B), 200 ml/kg (C), 250 ml/kg (D), and 300 ml/kg (E). The result showed that honey supplementation in feed was effective to improve goldfish fingerlings resistance against Aeromonas hydrophila bacterial attack. The supplementation of honey in feed with 200 ml/kg was the best treatment for inducing goldfish fingerlings against A. hydrophila. This was proven by the increased white blood cells (leucocytes) (27.84 ± 5.07%) followed with no apparent clinical symptoms after attacked by A.hydrophila, such as hemorrhage, necrosis, exophthalmia or dropsy, besides showing the highest survival rate with 73.33 ± 11.5%. Keywords : Aeromonas hydophila, goldfish, honey, leucocyte, resistance ABSTRAK Serangan bakteri Aeromonas hydrophila dapat menyebabkan kematian ikan mas koki hingga mencapai 100%.

Ammonia results from decomposition of effluents organic matter, e.g. feed wastes and fish faeces. Its un-ionized form can be toxic because diffuses easily through fish respiratory membranes, damaging gill epithelium and impairing gas exchanges. The objective of this work was determining the 96-hour CL50 of un-ionized ammonia for newly hatched pejerrey Odontesthes bonariensis larvae. Trials were set up completely randomized design, with three different concentration of un-ionized ammonia (0.57, 0.94, and 1.45 mg L-1 NH3-N) and a control treatment (n = 3). Experimental units were 20-L, aerated aquaria stocked with 20 larvae (average weight 3.9 mg). Pejerrey larvae exposed to un-ionized ammonia during 96 hours present 50% mortality at 0.71 mg L-1 NH3-N.
