Live weight prediction of cattle using deep image regression

AbstractThe objective of this work was to evaluate the ultrasound method as a tool forin-vivobreast and abdominal fat prediction on Campero-INTA broilers. Breast length (mm), width (mm), surface (mm2; ultrasound) and depth (mm; ultrasound), and abdominal fat depth (mm; ultrasound) were measured at 65-66 and 72-73 days of age on 96 males. At 79 days of age, the broilers were weighed and slaughtered. Breast and abdominal fat weights (g) were obtained. Multiple regression equations were fitted using live weight (g) andin-vivomeasurements to predict breast and abdominal fat weights and proportions (g/g). The best model for each case was selected by the Stepwise procedure. Equations fitted were verified using another set of data. Breast weight prediction using live weight and breast length in the model was as accurate as using live weight and breast depth. The former is recommended for breeding work. Abdominal fat weight prediction using ultrasound measurements of fat was less accurate than breast weight prediction. Repeatabilities for ultrasound breast measurements were higher (0·72 to 0·73) than those for abdominal fat (0·51 to 0·52). Operator effect may be important when training levels are different.

A method to estimate total dry matter intake (DMI) of individual dairy cows on commercial farms was developed to aid nutritional research on commercial farms (Wicks, 2001). Recently a second validation of the model was carried out using cows from the Agricultural Research Institute of Northern Ireland (ARINI) dairy herd. The results from the validation process at Wye and ARINI are shown and the mean square prediction error (MSPE) of the model for live weight prediction and DMI estimation were calculated.

The objective of this research was to process digital image to investigate the possibility of ducks weight estimation based on the software LabVIEW with the vision builder. In this study the images were record by the top-view camera. An ellipse fitting algorithm was applied to localize ducks within the stall. Estimating duck weight consists of these steps. First, image acquisition. Second, counts pixel of the samples. Third calculate duck weight by using samples pixel as the output. Results from this study showed that, the estimated ducks weight by using digital photos had 3.27% of the error when compare to the measured weight. The correlation coefficient of the body weight prediction equation from a comparison between measured (absolute) and estimated by camera for all duck is clearly high (R2=0.91). It was found that the system able to estimate duck weight with an acceptable error. So we can develop this research processing or build up the automatic sorting duck in the future. This method operated pretty well in prophecy live weight.

The objectives of this study were to evaluate the relationship between live measurements and carcass traits, and develop linear regression models to predict live weight and set of carcass traits in an indigenous guinea fowl. Twenty eight adult indigenous birds of both sexes were used for the study. Live weight and body measurements were obtained before slaughter while carcass traits were taken on hot carcass. Result obtained from descriptive statistics showed that, mean performance were 1208?6.86g, 22.17?0.13 cm, 8.94?0.07cm, 2.96?0.03cm, 34.23?0.19cm, 850.15?7.18g, 267.23?1.69g, 72.39?0.64g and 70.38% for body weight, body length, thigh length, keel length, chest circumference, carcass weight, breast weight, thigh weight and dressing percentage. All the traits except for keel length were positively (P<0.001) correlated to body weight. Chest circumference had the highest predictive power in live weight estimate (R2.558), while body weight stand out as the single most important variable in carcass weight and breast weight prediction (R2.820 and .902) This suggest that carcass weight and breast weight prediction can best be obtained using body weight, providing direction in developing model for selection and improvement of guinea fowl for meat production.

Weight Prediction

Data collected from 900 goats sampled from Borno, Sokoto and Ogun States from three different breeds on the following metric characters: Body Weight (BW), Age, Horn Length (HL), Ear length (EL), Shoulder width (SW), Neck circumference (NC), body length (BL), Withers Height (WH), Heart Girth (HG), Pouch Girth (PG), Tail Length (TL) and Scrotal circumference (SC) were subjected to stepwise multiple linear regression. Results obtained showed Live weight changes with body measurements were poorly to highly predictable with R2 values ranging between 0.000 - 0.031 in animals < 1 year old, 0.000-0.241in animals 1-2 years and 0.000-0.658 in animals 2 years and above. It was thus concluded that the low, moderate and high predictive power obtained from this study might be due to instability of regression coefficient at different ages and points also to decreasing environmental impact on growth with increase in age.

This study was undertaken to develop a year round fodder production model for small scale dairy farmers. Five pregnant dairy cows of Red Chittagong Cattle (RCC) genotype were selected. For rearing five cows, 66 decimal of land was selected from existing fodder plots under Pachutia Research Farm at Bangladesh Livestock Research Institute (BLRI), Savar, Dhaka. The selected land was divided into two parts (33 decimal in each). One part was brought under perennial (Napier-4 and Splendida) and the 2nd part of land for seasonal (Maize & Matikalai) fodder production. Data on live weight and live weight gain of cows, birth weight of calves, feed intake, milk production, actual biomass yield for both perennial and seasonal fodder, yearly manure production were recorded and calculated. Napier-4 grass, splendida, maize, straw, silage were supplied to the experimental cows according to the seasonal availability in different months. Concentrate mixture were also supplied consisting of wheat bran, kheshari (red gram), soybean meal, maize crushed, til oil cake, DCP and common salt. Economics of the model revealed that considering the sale of milk, calves and manure and cost included only feed and land leased, a farm/family rearing 5 indigenous dairy cows with his/her family labours, he/she could earn around BDT 98 thousand in a year (1$ = 85 BDT) and the benefit cost ratio of the model on total variable cost and total cost were 1.86 and 1.66, respectively. Therefore, it may be recommended that a farmer having 5 adult dairy cows with 66 decimal land under fodder cultivation may earn substantial share of his/her family income as small-scale rural dairying.

The article presents the data obtained as a result of carrying by employees of the Research Institute of sheep and goat breeding, a branch of the FSBSI "North Caucasus FARC", the scientific and economic experience to study the efficiency of a new fodder additive "Organic" on the productive and physiological indices of bull-calves during the completion of growing in the conditions of the farm "Pata" agricultural enterprise in the Karachay-Cherkessia Republic. The statement of the experience and all researches were carried out according to generally accepted methods. In the course of the experiment, the following indices were studied: the chemical compound of forages, the dynamics of a live weight gain in the experimental stock, hematological parameters, control slaughter data, economic indices. Completed researches have shown positive result from the use of the fodder additive "Organic" in bull-calves diets: an increase in the average daily gain of live weight by 25%, a slaughter yield by 1% and a high level of profitability – 27%. Thus, the additional introduction of "Organic" in a diet of young horned cattle in the 2nd experimental group promoted more intensive metabolism, stabilization of a physiological state, increase in productivity and, as a consequence, profitability of beef production. Researches in this direction reveal the latent fodder reserves promoting increase in the productivity of agricultural animals.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.
