The Impact

In recent decades, pigs and pork have been the central elements of Chinese agricultural systems, food security, and diet. China’s rapid income growth has induced a significant change in food consumption patterns, and hog production has received utmost attention from both, the Chinese government and the public. While the impact of Farmer Field Schools (FFS) on crop cultivation has been widely studied, few studies have examined the impact of FFS on hog production. This study uses data collected from 222 hog farmers in Beijing to examine the impact of FFS on the productivity of hog production, focusing on its three main indicators: feed conversion ratio and the mortality of sows and piglets. We found that farms that participated in FFS programs significantly improved the feed conversion ratio of hog production, particularly in small scale hog farms. On average, FFS reduced the feed conversion ratio for herd sizes of 1000, 500, and 200 by 6.8%, 10.7%, and 14.0%, respectively. We did not find evidence that farms that participated in FFS programs had a significant impact on minimizing the mortality of sows and piglets. This study suggests that the knowledge training model of the FFS program could also work in fields other than crop cultivation. Furthermore, we suggest that more attention could be paid to extension services diffusing knowledge of vaccination and disinfection in hog FFS programs.

The Impact

This study was carried out to evaluate the impact of raw and cooked wild cocoyam (Caladium bicolor) on the performance of broiler chicks. Wild cocoyam corms were divided into two batches. One batch was ground raw and the other batch was cooked before grinding. Wild cocoyam meals so prepared were used to formulate 5 broiler starter diets at dietary inclusion levels of 0, 10 and 20% raw and cooked wild cocoyam respectively. 180 7-day-old Anak broiler chicks were randomly allotted to the five treatment diets in a Completely Randomized Design (CRD) and each group was further subdivided into three replicates of 12 birds. Measurements recorded included weight gain, feed intake, feed conversion and protein efficiency ratios and economics of production. Results shows significant (p<0.05) improvement in feed intake, weight gain, feed conversion ratio and PER of birds fed cooked wild cocoyam meals. Marked (p<0.05) reduction was however, obtained in feed intake and feed conversion ratio of birds fed raw wild cocoyam diets. There was no significant (p>0.05) difference between birds fed maize-based (control) and cooked wild cocoyam diets. Results of this experiment indicated that cooking improved the nutritive value of wild cocoyam since birds fed cooked wild cocoyam diets produced best results than those fed raw wild cocoyam meal and that starter broilers could tolerate up to 20% dietary inclusion level of cooked wild cocoyam without any deleterious effect. Economics of production showed that cooked wild cocoyam diets were more profitable as regards the cost of feed per kg weight gain (N) and thus cost savings (%).

The Impact

An experiment was conducted to determine the impact of Plantain (PL), Bio-Sel-E and commercial broiler diet on the growth performance, feed conversion ratio, performance index and carcass yield of broiler. A total of 160 day old broiler chicks (Cobb-500) were randomly distributed into four groups with four replication in each group and having 10 birds in each replication. Basal diet was used for group 1 (control), Basal diet was supplemented with PL (0.5% of DM basis) and Bio-Sel-E (5g/50 birds in drinking water) for group 2 and 3 respectively and for group 4 used commercial broiler diet (Quality Feed Ltd.). Total feed intake was similar among the groups. Feed conversion ratios of PL diet, Bio-Sel-E diet, and commercial broiler diet were comparable, and were lower (P<0.05) than the control diet. Significantly higher body weight gain and performance index were found in PL, Bio-Sel-E and commercial broiler diet groups than control diet. The dressing yield of PL diet and commercial broiler diet were comparable, and they were higher (P<0.05) than Control diet and Bio-Sel-E diet. It could be concluded that the Supplementation of 0.5% PL in the diet had positive effect on growth, feed intake, feed conversion ratio, performance index and carcass characteristics of broilers almost similar of Bio-Sel-E and commercial broiler diet.

The Impact

SUMMARYLivestock production is increasingly facing consumer concern about the environmental impact of different production systems. In order to provide a detailed insight into the contribution of pork production, a life-cycle assessment (LCA) of average German pork production was performed. In this way, the global warming potential was estimated at 3·22 kg CO2-eq/kg pork, eutrophication at 23·3 g PO4-eq and acidification at 57·1 g SO2-eq. The functional unit was 1 kg pork as a slaughter weight. The analysis aimed at identifying those farm parameters which had most impact on the LCA results. For that purpose, a deterministic pig farm model was developed which reflected all the processes of a pig farm, while focusing on five distinct areas: general farm information, biological performance, basic feed data, manure management and resource use and emissions. In this way, it was possible to vary the level of performance parameters from farrowing (piglet losses and number of piglets born alive per litter) and finishing stage (lean-meat content, daily weight gain, animal losses and feed conversion ratio). The number of piglets born alive, the lean-meat content and the feed conversion ratio were identified as having the greatest influence on the results. In comparison with average pork production, the values of the impact categories increased and decreased by up to 4·7%. The results show that the fertility of sows and the feed management of finishers should be optimized to mitigate environmental impacts at pig farm level.

This study aimed to examine the impact of dietary salt-based mineral and phosphorus supplements on mean body weight, survival rate, and feed conversion ratio of Litopenaeus vannamei (white shrimp) reared in brackish water. The experiment was performed randomized design with three replicates in each treatment used twelve 40 L rectangular polymethyl methacrylate containers reared 45 days. The four treatments in this study were based on the concentration of salt-based mineral and phosphorus supplements (control or 0 ppm, one ppm, two ppm, and three ppm) in dietary of white shrimp. The results showed that using salt-based mineral and phosphorus supplements in dietary of white shrimp positively impacts mean body weight, survival rate, and feed conversion ratio. Increasing the concentration of salt-based mineral and phosphorus supplements increased mean body weight and survival rate and reduced feed conversion ratio of white shrimp. The mean body weight, survival rate, and feed conversion ratio of white shrimp were achieved with three ppm of dietary salt-based mineral, and phosphorus supplements reared 45 days was 5.98 gr, 88.57%, and 1.45, respectively.

The reduction of phosphorous waste from farmed rainbow trout (Oncorhynchus mykiss) was attempted by feeding diets of reduced P content. The protein source was fishmeal in which the bone fraction had been removed. This was achieved either by solubilizing the fish material (press cake) by enzymatic treatment and subsequent filtering, or by removing the fish bones by a skin/bone separator. Two fish species were used, sand eel (Ammodytes marinus) and sprat (Sprattus sprattus). Due to the small size of the fish, only bones were retained in the skin/bone separator. Traditional fishmeal from the same species were used for control experiments. The fishmeal samples were used together with other ingredients in a traditional extruded dry feed formulation (Ecolife 19). The diets were used in full scale experiments in a fresh water fish farm in Denmark, as well as in small scale experiments in aquaria. Direct calculations on the feed conversion ratio and the specific growth rate on both experiments showed that the enzyme treated codes performed less well than the other codes. However, when compensating for the different energy content of the diets, the enzymatic treatment did not give rise to a higher feed conversion ratio, nor did it give rise to a lower average growth rate than the other codes. It was not possible to make any final conclusions with respect to the effect of the enzymatic treated fishmeal on the pollution risk from P. This was due to large variation on the P determinations.

The objective of the study is to compare the practical results with the predicted results by Crossbreeding Effects (CBE) software on pig crossbred based on daily gain, backfat thickness and feed conversion ratio. Another purpose of this study is to predict those three traits among some expected hybridization. This research was conducted on pig farm at Binh Thang Research and Development center from 2013 to 2017. In this study, for each pair of purebred Duroc and Pietrain, Duroc and Landrace, Pietrain and Landrace, twelve hybridizations were analyzed, nine unhybridizations were predicted by CBE software. The results showed that there was no significant difference between the predicted and actual data. With some unhybridization crossbred , the predictions showed high reliability (P<0.05). Based on the predicted data of CBE software , some traits of the crossbred animals would not be improved, therefore, it was not necessary to conduct these hybridizations

Foot Disease

Footpad dermatitis (FPD) is a major foot disease in modern poultry production, and it affects both poultry health and animal welfare. It refers to inflammation and necrotizing lesions on the plantar surface of the footpads and toes. We investigated the effects of providing a swimming pool and different floor types on growth performance and FPD score in indoor-reared White Roman geese. Forty-eight male and 48 female White Roman geese were randomly allocated to pens with or without a swimming pool and with either mud or perforated plastic floor and reared from 15 to 84 days of age. Growth performance measurements included feed intake (FI), weight gain (WG), and feed conversion ratio (FCR). FI, WG, and FCR were significantly decreased at various growth periods in geese provided with a pool. Lower WG and bodyweight for the perforated plastic floor group were found at 15–28 and 28 days of age, respectively. The geese reared on the perforated plastic floors without a pool had higher FPD scores at 70 and 84 days of age than those with other rearing conditions. A higher incidence of FPD score 1 was observed in geese raised without a pool. In conclusion, providing a pool can improve footpad health in indoor-reared White Roman geese but may not benefit growth performance.
