Two experiments were conducted to determine the response of Creole male goats treated with long days and melatonin implants, anovulatory does effect using males only artificially days. All animals allocated open sheds. In Exp. 1, one group was under natural photoperiod (CG; n = 7); second submitted 2.5 mo followed by insertion two s.c. implants (LD+MEL; third subjected (LD; 7). Testicular weight measured every 2 wk. Plasma testosterone concentrations determined weekly. A treatment x time...
Two experiments were conducted to determine whether the failure of males induce sexual activity in goats during seasonal anestrus is due unresponsiveness females male stimulus or insufficient stimulation from males. In first study, one group (sexually inactive, SI; n = 4) was kept under natural photoperiod while other active, SA; subjected 2.5 mo long days (16L:8D) and received 2 s.c. implants melatonin. later, different flocks anovulatory previously separated bucks exposed either SI (n 34)...
Water is a vital resource for sustaining life and numerous processes within the transformation industry. It finite resource, albeit one that can be renewed, thus sustainable management imperative. To achieve this objective, it necessary to have appropriate tools assist with planning policies its management. This paper presents time series analysis approach measure predict pattern of water consumption by humans throughout subsectors (domestic, commercial, public sector, education, industry,...
Reproductive seasonality is observed in some breeds originating from or adapted to subtropical latitudes. In 'photoperiodic flexible breeds', such as Australian cashmere goats, the annual breeding season can be manipulated through nutrition, whereas rigid Creole goats Mexico, sexual activity controlled by altering photoperiod. males latter breed, artificial long days, whether not accompanied administration of melatonin, stimulate during non-breeding season. These treated are able induce...

Summary Background: high environmental temperature coupled with humidity can result in reproductive failure dairy cattle, a drastic reduction efficiency of herds. Objective: to study the effect on reproduction performance Holstein cows treated recombinant bovine somatotropin (rbST) throughout lactation an arid environment. Methods: variables (n = 18,037 services) from large herd were evaluated respect maximum temperature-humidity index (THI) prior breeding, breeding day, and after breeding....
The aim of the present study was to use a non-linear regression approach investigate relationship between litter birthweight and size five breeds goat under intensive conditions in hot arid environment. Litter-size litter-weight data on 20 117 kids from 13 685 litters representing breeds, namely Saanen, Toggenburg, French Alpine, Anglo-Nubian Granadina, were compared evaluate this relationship. Regardless breed, for born as twins, triplets quadruplets was, average, 92%, 87% 83%,...
