Slaughtering of food animals not only provides meat but also provide valuable byproducts to the mankind. By slaughtering and processing of meat animal, only one third portion is meat while the rest of the portion includes byproducts and waste, which need to be adequately processed and efficiently utilized in various ways. Efficient utilization of byproducts has direct impact on the economy as well as environmental pollution. By products include meat and bone trimmings, blood, fat, intestinal content etc., among which fat is an important slaughter house byproduct which is used for edible as well as inedible purposes. Fat is obtained by rendering process, which may be dry, wet and low temperature rendering depending upon the utilization of finished product. Recovered edible and inedible fat may be used for various food and technical purposes which is directly or indirectly improves the economics of slaughter house industry.

A field study was carried out in the Rewa district; Incidence of reproductive disorders studied in seventeen villages of potential dairy pocket of Rewa district includes peri-urban and rural areas. After conducting survey on 409 animals of 193 farmers the total percentage of true anoestrus cows was 35.45 per cent followed by 15.54 per cent sub-oestrus animals, 8.31 per cent repeat breeders, 3.91 per cent retention of placenta (ROP) and 3.17 per cent of prolapse cases.
So the total percentage of reproductive disorders was 66.38 per cent. Reproductive disorders may be due to anoestrus and other problems related to mineral and other deficiencies in feeds and fodders in field conditions.
Keywards: Anoestrus; Incidence; Prolapse; Repeat breeders; Retention of placenta.
 

The present investigation was planned to differentiate various stages of estrus i.e. onset of estrus, standing heat and non-estrus conditions in sahiwal cows by observing various haematological attributes. The experiments were conducted on ten healthy, cyclic Sahiwal cows maintained at Livestock Farm Complex (LFC) of College of Veterinary Science & Animal Husbandry, DUVASU, Mathura.The selected Sahiwalcows were observed for signs and symptoms of heat/estrus.Detection of onset of post-partum estrus was performed by observing the first response of teaser bull and rectal palpation of cow at every 3 hours interval after onset of estrus. Blood sample was collected for haematological changes duringtheir onset of estrus, standing heat and non-estrus stages. The mean values for RBC (6.79±0.10 X106/ mm3), WBC (10.65±0.18 X103/mm3), PCV (33.41±0.54%), and haemoglobin (11.47±0.15 mg/ dl) of experimental cows were found to be significantly (P<0.01) higher during standing heat condition as compared to onset of post-partum estrus and non-estrus stages in Sahiwal cows. On the basis of above factshematological attributes (RBC count, WBC count, blood hemoglobin and PCV) may be used for precise identification of onset of estrus,standing heatand non-estrus stages in Sahiwal cows. Keywords: Cyclic; Estrus; Hematology; PCV; Sahiwalcows.

An experiment was performed to access the comfort level with the help of blood biochemical profile in buffalo’s heifers. Randomly eighteen healthy Murrah buffaloes of almost uniform in age, body weight and health status selected for experiment at Livestock Farm Complex (LFC), College of Veterinary Sciences & Animal Husbandry, DUVASU, Mathura up to three month duration. The selected animals were randomly divided into three groups viz. Concrete flooring (T1), Cow dung bed flooring (T2) and Rubber mat installed flooring. The study revealed that mean of total protein (mg/dl) in buffalo heifers were observed significantly (P>0.05) higher in T2 & T3 group (6.08 and 6.11) than T1 (5.45), while the total globulin (mg/dl) was significantly higher in T3 (2.60) than T1 & T2 (1.24 and 1.74) after 30 days of experimental period. The blood urea nitrogen (mg/dl), plasma creatinine (mg/dl), plasma glucose (mg/dl), plasma cholesterol (mg/dl) and plasma albumen (mg/dl) have on any significant changes during different phases of experimentation.
