“…The positive correlation of NEFA with GH (0.699; P<0.01) and PRL (r=0.576; P<0.01) was attributed to role of these hormones in mobilization of body reserves. However mean plasma glucose and NEFA concentrations observed in this study corroborates earlier report in Murrah buffaloes (Prasad and Singh, 2010). The changes in the hormones and milk yield in this study indicate that cows with different temperaments vary in their basal physiology as well as their behavioral and physiological responses to milking and stress associated with being milked in a novel environment (Sutherland et.…”

“…Growth hormone has been reported to be the main galactopoietic hormone in cows and buffaloes (Mepham, 1987;Ludri et al, 1989). Recent studies indicate role of prolactin in milk synthesis and an interactive role prolactin and GH in maintaining milk secretion (Knight and Flint, 1995;Prasad and Singh, 2010). Milk in the udder of cow is mainly stored in the alveolar compartment (80 to 100%) which could be harvested by exogenous oxytocin (Ludri and Singh, 1987).…”

The effect of milking temperament on plasma hormones, metabolites, milk yield and composition in lactating Murrah buffaloes was studied. Animals were selected from the institute herd and grouped as docile and nervous buffaloes, based on temperament score before and during milking. Blood sampling times were; before milking (-20 min.), after concentrate intake, after teat massage, during milking and 20 min. post-milking. Plasma prolactin (PRL), growth hormone (GH) and cortisol (CORT) concentrations were measured by enzyme-immunoassay procedures. Milk yields of individual buffaloes were recorded and milk composition (fat, protein, lactose, SNF, SCC) determined. Milk yield was significantly lower (P<0.05) in nervous buffaloes in comparison to docile buffaloes. Mean fat, protein, lactose and SNF varied non-significantly between the groups. Milk SCC and plasma NEFA concentration was more (P<0.05) in nervous buffaloes than in docile buffaloes. Milking temperament significantly influenced plasma PRL (P<0.01) and CORT release (P<0.05) but GH was unaffected. Concentrate feeding prior to milking induced release of plasma PRL and CORT without affecting GH and oxytocin levels. Teat stimulus further enhanced release of PRL, oxytocin and CORT hormone in both the groups. Plasma PRL, cortisol, oxytocin and GH varied significantly (P<0.01) before, during and after milking (P<0.01). Basal PRL, GH and CORT were attained 20 minutes after the completion of milking in both the groups. The results show that the behavior of buffaloes at milking influenced release of galactopoietic hormones (PRL, CORT, GH and oxytocin), milk yield and SCC, while milk fat, protein, lactose and SNF remain unaffected.

“…Plasma GH concentration increased (p<0.05) in PFG cows during mid lactation (Singh et al, 2014) and postpartum. The GH has been found to be galactopoetic in the cows (Yadav, 2014) and buffaloes (Prasad and Singh, 2010).…”

“…Attempts have been made to augment milk production from dairy animals with bovine somatotropin which is galactopoietic in nature (Bachman et al, 1992;Singh and Ludri, 1994). Because of the environmental hazards and secretion of hormone into milk, the application of this technology could not become popular (Prasad and Singh, 2010). Subsequently researchers focused on the use of non-hormonal preparations and herbal medicine to augment lactation because they augment milk yield without affecting the energy balance (Singh et al, 2012).…”

Pregnancy and lactation are the physiological states which modify metabolism in animals and induce stress. The period of transition between late pregnancy (-3 weeks) and early lactation (+3 weeks) presents huge metabolic challenges in terms of energy balance, plasma metabolites and hormonal changes. High rates of Body Condition Score (BCS) losses are associated with a severe negative energy balance conditions immediately after the calving. Energy deficiency due to decreased dry matter intake during the periparturient period results in increased lipolysis of body fat. The release of non-esterified fatty acids and higher β-hydroxybutyrate concentrations are indicative of lipid mobilization and fatty acid oxidation. Animals have to utilize their body reserves to support lactogenesis and milk production resulting in metabolic disorders and sub-optimal milk yield under these conditions. Most of the lactating animals are fed crop residues in the tropical countries, which are generally low in energy, protein and minerals. Increased amount of energy secreted into milk fat and lesser feed intake puts high yielder cows and buffaloes in negative energy balance (NEBAL), metabolic disorders and suboptimal milk production. Maximizing the energy intake by increasing the energy density of diet is a logical feeding strategy during transition period and in early lactating animals. Feeding large amounts of cereal grains decrease ruminal pH, ruminal fiber digestibility, acetate/propionate ratio, milk fat concentration and increase the risk of ruminal acidosis. Scientific interventions have been carried out from time to improve energy balance by supplementing bypass fat and proteins. Bypass fats are commonly referred to as ruminal inert fat, protected fat and escape fat and are more expensive per unit of energy provided compared to commodity fats. Calcium salts of fatty acids increase milk yield and fat contents but partially degrade in the abomassum. Prill fat, a bypass fat is available in different forms and augments productive performance of lactating animals by getting digested in the small intestine. However response varies depending upon the milk production levels and the body condition of animals. The present review discusses the role of bypass fat in enhancing the milk production performance and its effect on hormones, digestibility coefficients and energy balance.

“…Use of recombinant bovine somatotropin (rbST) as a powerful tool to enhance cattle performance in terms of milk production has been extensively reviewed by Peel and Bauman [1], Radcliff et al, [2], Van Baale et al, [3], Prasad and Singh, [4], Abdelrahman et al, [5], Macrina et al, [6] and Mellado et al [7] and in buffaloes by (Helal and Lasheen,[8] and Khaliq and Rehman, [9]. Mean volume injected have varied from 5 to 50 mg/day (Peel and Bauman [1], Radcliff et al, [2], Van Baale et al, [3], Prasad and Singh, [4], Abdelrahman et al, [5], Macrina et al, [6] and Mellado et al [7]). While most studies either pertain to cattle, crossbred animals (Chalupa et al, [10] and Radchiff et al, [2]) and to some extent with sheep (Fernandez et al, [11]) and goats (Disenhaus et al, [12]).…”

This study was performed to investigate the effect of rbST treatment on some biochemical parameters in addition to values of thyroid hormones in Kundhi buffaloes. Sixteen Kundhi buffaloes were divided into two groups. Group-A (N=8) served as control and Group-B (N=8) was treated with 250 mg of rbST fortnightly for 1 st lactation. Blood samples were collected weekly during lactation period from day one to 60 as pre-treatment values and then from day 61 to completion of 1 st lactation in Kundhi buffaloes as post-treatment values. The findings revealed overall non significant variation in the serum biochemical and thyroid hormone values between control and rbST treated buffaloes, whereas, significant differences were observed during various physiological and weather conditions in both groups. Glucose and uric acid values were observed higher during parturition and winter season in Kundhi buffaloes. Protein level was higher in rbST treated buffaloes during open days.
