Background: Feeding of fermented feed is not popular among the pig farmers inspite of manifold advantages as preparation is laborious, involves technical knowledge requiring considerable time. An attempt was made to standardise a preparation method of FLF and comparative assessment was made with dry and liquid feed in LWY pigs. Methods: Twenty-four weaned LWY piglets (11.45±2.42 to 11.46±2.37 kg) were assigned - dry feed (T1), Liquid feed (T2), liquid feed fermented with Lactobacillus acidophilus (T3) and liquid feed fermented with Enterococcus faecium (T4) in a 180 days feeding trial. Liquid feed was prepared by mixing feed and water at 1:2 (w/w) and the FLFs were prepared by fermenting liquid feed with Lactobacillus acidophilus for T3 and Enterococcus faecium for T4. Pigs were fed individually ad libitum considering each piglet as replicate. Nutrient digestibility was estimated at 18th and 30th week of age conducting two feeding trials. Carcass traits and sensory quality of pork were evaluated by slaughtering 3 pigs from each treatment at the end of trial. Result: No significant effect (P greater than 0.05) of FLFs was observed in feed intake in the growing phase, but it was significantly high in T3 and T4 in the finishing phase. Significantly (P less than 0.05) high body weight gain with improvement of 17.76% in T3 and 17.71% in T4 were recorded. Apparent nutrient digestibility was better in T3 and T4 and crude protein digestibility was significantly (P less than 0.05) high in T3 in finishing phase. Significantly improved feed efficiency was recorded for T3 and T4. The feeding cost/kg body weight gain was Rs. 128.36, 120.43, 112.87 and 115.51, respectively for T1, T2, T3 and T4. Significantly high dressing% and carcass length with positive effect on water holding capacity were observed for feeding FLFs, but without any significant effect on proximate composition and sensory attributes of pork.

Abstract The aim of the study was to evaluate prediction methods, validation approaches and pseudo-phenotypes for the prediction of the genomic breeding values of feed efficiency related traits in Nellore cattle. It used the phenotypic and genotypic information of 4,329 and 3,594 animals, respectively, which were tested for residual feed intake (RFI), dry matter intake (DMI), feed efficiency (FE), feed conversion ratio (FCR), residual body weight gain (RG), and residual intake and body weight gain (RIG). Six prediction methods were used: ssGBLUP, BayesA, BayesB, BayesCπ, BLASSO, and BayesR. Three validation approaches were used: 1) random: where the data was randomly divided into ten subsets and the validation was done in each subset at a time; 2) age: the division into the training (2010 to 2016) and validation population (2017) were based on the year of birth; 3) genetic breeding value (EBV) accuracy: the data was split in the training population being animals with accuracy above 0.45; and validation population those below 0.45. We checked the accuracy and bias of genomic value (GEBV). The results showed that the GEBV accuracy was the highest when the prediction is obtained with ssGBLUP (0.05 to 0.31) (Figure 1). The low heritability obtained, mainly for FE (0.07 ± 0.03) and FCR (0.09 ± 0.03), limited the GEBVs accuracy, which ranged from low to moderate. The regression coefficient estimates were close to 1, and similar between the prediction methods, validation approaches, and pseudo-phenotypes. The cross-validation presented the most accurate predictions ranging from 0.07 to 0.037. The prediction accuracy was higher for phenotype adjusted for fixed effects than for EBV and EBV deregressed (30.0 and 34.3%, respectively). Genomic prediction can provide a reliable estimate of genomic breeding values for RFI, DMI, RG and RGI, as to even say that those traits may have higher genetic gain than FE and FCR.

QUAIL (Coturnix-Coturnix Japonica) GROWER PERFORMANCE SUPPLIED WITH MANURE FLOUR DEGRADED BY BLACK FLY LARVAE (H.ILLUCENS L.) TO REPLACE FISH MEAL. This study aims to determine the manure yield of black fly larvae replacing fish meal in the quail feed of the grower phase. The materials used in this study were 100 unsexed quails, 3 weeks old; the dimension of cage was 40 x 40 x 20 cm. The quails were arranged randomly in each unit. The study was realized by using a completely randomized design (CRD) with 4 treatments and 5 replications. The treatments were R0 = 0% degraded manure flour (MHD); R1 = 4% MHD flour; R2 = 8% MHD flour; R3 = 12% MHD flour. The research variables consisted of ration consumption, body weight gain and feed efficiency. The results obtained showed that treatments provide a very significant influence (P <0.01) on ration consumption. Body weight gain and feed efficiency were not significant different (P> 0.05). The conclusion of this study is that MHD flour up to the 12% level can be used in quail rations replacing fish meal. Keywords: Quail, MHD, Fish meal.

Forty steers were intensively finished in yards on rations of 90 per cent sorghum grain and 10 per cent of either sorghum silage or stubble. There were no significant differences in rate of body weight gain or efficiency of feed conversion of steers fed the two rations. The experiment commenced on July 2, 1965. An abrupt increase at this time in daylength by flood-lighting, for two 2-hour periods daily, had no significant effect on rate of body weight gain, feed efficiency or coat shedding of steers subjected to natural seasonal increases in daylength. The administration of a cobalt pellet to steers fed a low-cobalt sorghum grain had no effect on coat shedding or rate of body weight gain.

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.

Milk Feeding

Thirty-two male Holstein calves, beginning at 1 wk of age, were used to estimate differences in weight gain between two feeding levels and two feeding frequencies over a period of 3 wk. Calves were randomly assigned to one of the following four treatments: whole milk (WM) fed at 10% of body weight (BW) twice a day; WM fed at 10% BW, three times a day; WM fed at 12% of BW, in two feedings per day, or WM fed at 12% of BW, in three feedings per day. Body weight gains and feed conversions were 279 and 437 g per day and 12.02 and 9.51 kg whole milk per kilogram of gain for the 10 and 12% levels of feeding, respectively. There was a trend towards increased rate of gain and improved feed efficiency when calves were fed twice compared to three times a day. Cost of medication was not influenced by level or frequency of feeding. It was concluded from this study that feeding whole milk at 12% of body weight was preferable to feeding at the 10% level of intake. Key words: Milk feeding, level, frequency, dairy calves
